Answer:

These cells are usually found in all plant roots and mainly involved in providing support to the plants.

Explanation:

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

SKELETAL MUSCELES CARDIAC MUSCLES SMOOTH MUSCLES

Explanation:

SKELETAL MUSCLES -: There are long, cylindrical, and striated skeletal muscle cells. They are multi-nucleated, which means they have more than one nucleus. This is because from the fusion of embryonic myoblasts, they are created. Each nucleus controls the sarcoplasm's metabolic demands around it. There are high energy requirements for skeletal muscle cells, because they contain several mitochondria in order to generate adequate ATP. Examples of skeletal muscles: arms and legs- The muscles that belong to the arms and legs feature in pairs. Abdomen and Back- These muscles are connected to the various sets of skeletal muscles that run across the torso.CARDIAC MUSCLES -: Cardiomyocytes have a short and narrow outline and are fairly rectangular. They are about 0.02 mm wide and 0.1 mm (millimetres) long, respectively. There are many sarcosomes in cardiomyocytes, which provide the required energy for contraction. Cardiomyocytes usually contain a single nucleus, unlike skeletal muscle cells. Cardiomyocytes, although they contain more sarcosomes, normally contain the same cell organelles as skeletal muscle cells. example - cardiac muscle is present in heart. SMOOTH MUSCLES -: Smooth muscle cells have a single central nucleus and are spindle-shaped. They range in length from 10 to 600 μm (micrometers), and are the tiniest type of muscle cell. In the expansion of organs like the kidneys , lungs, and vagina, they are elastic and therefore essential. As in cardiac and skeletal muscle, the myofibrils of smooth muscle cells are not aligned, meaning they are not striated, hence the term smooth. example of smooth muscles -: Walls of blood vessels ,  Walls of stomach , Ureters ,  Intestines ,  In the aorta (tunica media layer),  Iris of the eye. ,Prostate  and  Gastrointestinal Tract.

The interaction between the root and shoot systems during nutrient transport can be described as a coordinated effort to absorb, transport, and distribute water and nutrients throughout the plant.

Roots are a fundamental part of the vascular plants, which are plants with a system of specialized tissues for transporting water, nutrients, and organic compounds throughout the plant. Roots anchor the plant to the ground and absorb water and minerals from the soil. They also store food and nutrients for the plant to use during times of stress.

The shoot system refers to the above-ground parts of the plant, including the stem, leaves, and reproductive structures (such as flowers and fruits). The stem provides structural support for the plant and serves as a conduit for transporting water, nutrients, and organic compounds between the roots and the leaves.

Answer:

How do the nutrients found in plants function in plant DNA?

Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.

Is the function of plant DNA similar to human DNA?

How much DNA do plants share with humans? Over 99%? ALL animals and plants share the same DNA which is basically a code of only 4 'letters' which code for the same amino acids from which all proteins are made.

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

Editing the CFTR gene can potentially impact gene expression in several ways, depending on the type of editing and the specific mutation being targeted, and one approach to editing the CFTR gene is through the use of gene therapy.

Gene therapy and gene editing are two potential approaches for treating CF by correcting the genetic defect responsible for the disease. Gene therapy involves introducing a functional copy of the CFTR gene into cells, while gene editing involves correcting the specific mutation in the CFTR gene responsible for CF. In gene therapy, a functional copy of the CFTR gene is introduced into cells using various methods, such as viral vectors, lipid nanoparticles, or gene editing technologies such as CRISPR-Cas9. Once the functional copy of the gene is successfully delivered into the cells, it can lead to increased expression of the CFTR protein, which can potentially improve the regulation of salt and water movement in and out of cells and reduce the severity of CF symptoms.

Hence, editing the CFTR gene can potentially impact gene expression in several ways, depending on the type of editing and the specific mutation being targeted, such as through gene editing.

High mass and low temperature

Explanation:

Nerve impulses are conducted fast in myelinated axons and slow on nonmyelinated axons. With the peripheral nervous system (PNS), myelin plays a role in regeneration.

Formed around nerves, particularly those in the brain and spinal cord, myelin serves as an insulating coating or sheath. Protein and fatty materials are the components that make up most of its composition. Electrical impulses may travel along nerve cells swiftly and effectively thanks to the myelin coating. These impulses or signals weaken if myelin is destroyed.

The spiral-shaped myelin sheath is a significantly lengthened and modified plasma membrane that surrounds the nerve axon. The Schwann cells in the peripheral nervous system (PNS) and the oligodendroglial cells in the central nervous system are where the myelin membranes originate from and are a component of (CNS).

Answer:

1) Weathering, Erosion, Disposition

2) Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.

3) The four forces of erosion are water, wind, gravity, and glaciers.

4) Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.

--------------------------------------------------------------------------------------------------------

Abrasion: Abrasion is the breaking down and wearing away of rock material by the mechanical action of another rock. Three agents of physical weathering that cause abrasion are moving water, wind, and gravity. Also, rocks suspended in thence of a glacier can cause abrasion of other rocks on Earth's surface. This would be a prime example of physical weathering, or mechanical weathering.

----------------------------------------------------------------------------------------------------------

Acid Precipitation: Acid rain causes less erosion than normal rainwater does. Rainwater can break down rocks by dissolving minerals in the rocks. Acid rain is rainwater that is more acidic than normal rainwater. Acid rain can also dissolve the minerals in rocks faster than normal rainwater can. This is chemical weathering.

--------------------------------------------------------------------------------------------------------

Animal actions: Animal and plant mobility is a factor in biological weathering. For instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand. A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock. This is an example of physical weathering.

---------------------------------------------------------------------------------------------------------

Ice wedging: Ice wedging ,sometimes known as frost wedging ,can also cause rocks to break apart. Ice wedging causes cracks in rocks to expand as water seeps in and the water freezes and expands opening the crack further. Rocks formed under pressure deep within earth can become exposed at the surface. This is physical weathering

----------------------------------------------------------------------------------------------------------

Oxidation: Oxidation is another kind of chemical weathering. It occurs when oxygen from air dissolves in water and combines with chemicals in the rocks to form oxides. if the rock contains a lot of iron, then oxidation produces a brown material called iron oxide. This looks like rust on the rock.

Weathering is the chemical and mechanical breakdown of exposed rock. The chemical changes alter the minerals and make them softer, and mechanical weathering physically breaks rock into smaller and smaller pieces.

Erosion is the REMOVAL of those chemically and mechanically softer and broken pieces of rock from their original locations, by gravity, water, ice or wind. Erosion is transport (and as a result, fresh unaltered rock is exposed to wind, water and weather, and THAT becomes weathered in turn). The material being transported is ‘sediment’: sand, silt, mud and gravel.

Deposition is when the weathered and eroded (transported) material is dropped and settles down elsewhere, forming a ‘deposit’ of transported rock material.

If this deposit remains undisturbed long enough, and is buried by enough arriving material, it will eventually go through compaction and chemical reactions forming cement between the grains - thus resulting in a brand new, sedimentary rock.

Weathering, erosion, transport, deposition, compaction and cementation are part of the ‘rock cycle’.

Let’s start with basalt that form at mid ocean spreading centers. At mid ocean spreading centers rock material from the earth’s mantle continuously melts due to continuous decreasing in pressure from the oceanic crust spreading at this point. The molten rock quickly cools at the earth’s surface and forms rock known as basalt that makes up the oceanic crust all over the world. The newly produced oceanic crust rock slowly moves towards a boundary with a continental crust where the oceanic crust subducts beneath the continental crust due to the oceanic crust having a higher density than the continental crust. This is where things get a bit more interesting.

Ribosomes do not directly create mutations, but cellular mechanisms such as DNA repair and checkpoints help control and minimize the occurrence of mutations.

Ribosomes themselves do not directly create mutations. Mutations, which are changes in DNA sequence, can occur due to errors during DNA replication or from external factors like radiation or certain chemicals. However, the cellular machinery, including ribosomes, plays a role in the control of mutations through various mechanisms. DNA repair mechanisms help identify and correct errors or damage in the DNA sequence, reducing the likelihood of mutations. Additionally, cellular checkpoints and regulatory processes monitor and control cell division, ensuring that accurate DNA replication and distribution occur, minimizing the inheritance of mutations to daughter cells.
