Answer:

C. It prevents water loss

A. It carries out photosynthesis

Explanation:

Cactus is a xerophytic plant i.e. it can survive in an environment with no or little amount of water. To do this, cactus plant possess certain adaptational features that allow it to be successful in a xerophytic environment.

One of these features is its reduction of leaves to spines in order to reduce the loss of water via transpiration. In respect to this, the swollen stem of the cactus plant called CLADODE performs the process of PHOTOSYNTHESIS in lieu of its absent leaves.

Also, the stem has a thick waxy coat as stated in this question in order to prevent the loss of water.

It can be inferred that pulmonary surfactant is important for maintaining the compliance of alveolar tissue in the lungs.

Compliance refers to the ability of a tissue to stretch or deform in response to pressure changes, and it is a key factor in determining lung function. In infants with Irrespective Respiratory Distress Syndrome (IRDS), there is an underproduction of pulmonary surfactant.

This leads to decreased compliance of the alveolar tissue, which makes it more difficult for the lungs to expand and contract properly during breathing. This can result in decreased oxygenation and increased work of breathing, leading to respiratory distress.

Pulmonary surfactant is a mixture of lipids and proteins that is produced by specialized cells in the lungs. It helps to reduce the surface tension of the alveoli, which allows them to expand more easily and reduces the risk of collapse between breaths.

A primary consumer obtains its energy by consuming producers, which is the third option, as producers are organisms such as plants and algae that can convert sunlight into energy through the process of photosynthesis.

When a primary consumer eats a producer, it breaks down the organic matter in the plant or algae and uses the energy stored within it to fuel its own cellular processes. This energy is transferred from the producer to the primary consumer, allowing the primary consumer to grow, reproduce, and perform other life functions. It is important to note that primary consumers are themselves consumed by other organisms, which are known as secondary consumers. This forms the basis of the food chain or food web in an ecosystem, where energy is transferred from producers to primary consumers to secondary consumers, and so on.

Information present in DNA indicates the sites where the RNA polimerase has to start tran

The genetic code of DNA influences protein synthesis and, ultimately, cell specialization within multicellular organisms by regulating the transcription and translation of the gene.

The DNA has the genes within it that later undergo the transcription process to form the mRNA and then undergo the translation process to form the polypeptide chain, or the protein. All the cells in an animal's body have the same genes, but they show differences in function and structure due to the cell's specification.

Some chromosomal genes are converted into heterochromatin during cell specification, and as a result, the gene never expresses and gets converted to that type of cell depending upon the stimulus that they get. Then, through transcription and translation, the rest of the genes present in the euchromatin regions are expressed.

Hence, the genetic code of DNA influences protein synthesis and, ultimately, cell specialization within multicellular organisms by regulating the transcription and translation of the gene.

1. fossils show our past ancestors and what we would have looked like before

2. you can use trace fossils (fossils left by an organism) to see how they lived and you can track how they lived their daily life

3.Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

Answer:

The observed image will not be sharp

Explanation:

When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to  to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).

Explanation:

When allele frequency and genotype frequency stay constant in a randomly mated population, the population is said to obey Hardy Weinberg equilibrium.

By using Hardy Weinberg Equilibrium for the given information; we have the following equations:

p + q = 1;  &

\(\mathbf{p^2+2pq+q^2 =1 }\)

Here; allele a = p

allele b = q

the heterozygous allele ab = 2pq

Since; a = 70%, then the percentage of allele a  = 0.70

Now;

p + q = 1

0.7 + q = 1

q = 1 - 0.7

q = 0.3

So, allele b = 0.3

Finally, to determine the percentage of the heterozygous population:

2pq = (2 × 0.7 × 0.3)

= 0.42

= 42%

Answer:

There are several ways in which negative human impact on the pH of Earth's oceans can be reduced. Here are two possible approaches:

Reducing carbon dioxide (CO2) emissions: The primary cause of ocean acidification, which lowers the pH of the oceans, is the increased absorption of CO2 from the atmosphere. To address this, it is crucial to reduce carbon dioxide emissions at their source. This can be achieved by transitioning to cleaner and renewable energy sources, promoting energy efficiency, and implementing policies to limit greenhouse gas emissions from industries, transportation, and power generation. By reducing CO2 emissions, we can slow down the rate of ocean acidification.

Promoting sustainable fishing and aquaculture practices: Overfishing and destructive fishing practices can disrupt marine ecosystems and contribute to the decline in ocean health. By promoting sustainable fishing practices, such as implementing fishing quotas, protecting marine reserves, and avoiding the capture of non-target species (bycatch), we can maintain the ecological balance of marine ecosystems. Additionally, supporting responsible and sustainable aquaculture practices that minimize environmental impacts and avoid the use of harmful chemicals can help reduce the negative human impact on ocean pH.

It's important to note that these are just two examples, and addressing ocean acidification requires a multi-faceted approach involving various stakeholders, including governments, industries, scientists, and individuals. Other measures, such as protecting coastal habitats, reducing pollution runoff, and raising awareness about the importance of ocean conservation, can also contribute to mitigating the negative human impact on ocean pH.

Greenhouse effect

Explanation:

Carbon-dioxide, methane and water vapor are green house gases, these gases absorb a large proportion of sunlight been reflected by the surface of the Earth. These absorption of sunlight leads to gradual increase in the annual temperature of the Earth. This phenomenon is known as greenhouse effect.

Greenhouse gases include carbon dioxide, methane, and water vapor. These gases absorb a significant amount of the sunlight that is reflected off the Earth's surface.

The progressive rise in the Earth's yearly temperature is caused by this absorption of sunlight. The term “greenhouse effect” refers to these phenomena.

Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3), and fluorinated gases are examples of greenhouse gases.

The warming effect of other greenhouse gases is amplified by an increase in atmospheric water vapor.

Earth's temperature rises in reaction to an increase in greenhouse gases like carbon dioxide and methane. This causes more evaporation from land and water surfaces.

Therefore, Greenhouse gases effect of Sunlight, carbon dioxide,

Rain Drop or Splash Erosion

The erosion due to the impact of falling raindrops on the soil surface leading to the destruction of the crumb structure is known as raindrop or splash erosion.

Sheet Erosion

It is the uniform removal of soil in thin layers from the land surface caused by the wind. Land areas with loose, shallow topsoil overlying compact soil are most prone to sheet erosion.

Rill Erosion

Rill erosion is a form of water erosion in which the erosion takes place through numerous narrow and more or not so straight channels called streamlets or head cuts. Rill is the most common form of erosion, which you can also observe during heavy rain.

Gully Erosion

Gully erosion occurs due to the runoff of surface water, causing the removal of soil with drainage lines. Gullies when started once, will move by headward erosion or even by slumping of side walls unless and un-till proper steps will be taken in order to stabilize the disturbance.

Stream Bank Erosion

Bank erosion is nothing but washing up away from banks of a stream or a river. It is different from the erosion of the bed of a watercourse, that is referred to as scouring. This type of erosion is also termed as Stream Bank Erosion.
