Answer:

calender of earth history

Explanation:

The geologic time scale is the “calendar” for events in Earth history. It subdivides all time into named units of abstract time called—in descending order of duration—eons, eras, periods, epochs, and ages.

Answer:The first two kingdoms to be classified were Regnum Vegetabile which were plants and Regnum Animale which were animals.

Earthworms and fish are similar because neither can live in saltwater environments.

Both earthworms and fish are different types of animals, but they do share some characteristics. While both options "Both have a closed circulatory system" and "Both breathe through their skin" are true for earthworms and fish, these characteristics are not unique to them.

Many other animals also have closed circulatory systems or respiration through their skin. However, the option "Neither can live in saltwater environments" is the most accurate and distinguishing characteristic between earthworms and fish.

Earthworms are terrestrial animals that require a moist environment to survive.

They lack adaptations to live in saltwater and are unable to tolerate the high salt concentration found in such environments. On the other hand, fish are adapted to live in aquatic environments, including both freshwater and saltwater habitats.

They possess specific physiological adaptations to regulate salt and water balance in their bodies, allowing them to survive in saltwater environments.

Therefore, the similarity between earthworms and fish is that neither can live in saltwater environments.

Plants cannot move, so they rely on pollinators to help transmit pollen (also known as plant sperm) through one plant to the next in order to produce genetically varied progeny.

Flowers are a plant's means of sexual reproduction, and how well a plant gets along with its pollinators determines how they look.

Thus, plants cannot move, so they rely on pollinators to help transmit pollen (also known as plant sperm) through one plant to the next in order to produce genetically varied progeny.

Answer:

Explanation:

The oldest oceanic crust is about 250 to 260 million years old. This sounds old but is actually very young compared to the oldest continental rocks, which are 4 billion years old. Why is the seafloor so young? It is due to the process of subduction; oceanic crust tends to get colder and denser with age as it spreads off the mid-ocean ridges. It gets so dense, that it sinks in the upper mantle (subduction). This is like a giant recycling system for the oceanic lithosphere. As the continental crust is lighter than the oceanic crust, the continental crust cannot subduct. We therefore still have some very old continental rocks at the surface of the Earth.

The oldest oceanic crust is approximately 250 million. The correct option is c.

The oldest oceanic crust dates back between 250 and 260 million years. This appears to be old, yet it is actually quite young in comparison to the oldest continental rocks, which are 4 billion years old.

It is due to the process of subduction; as it extends off the mid-ocean ridges, the oceanic crust becomes colder and denser with age. It becomes so dense that it settles in the upper mantle (subduction).

This is similar to a massive recycling mechanism for the marine lithosphere. Because the continental crust is lighter than the oceanic crust, it cannot subduct. As a result, we still have some very old continental rocks on the Earth's surface.

Therefore, the correct option is c, 250 million.

We can say that :

a.) The Sun has a stronger gravitational pull on Venus than it does on Earth. Venus has a shorter period of revolution around the Sun when compared to Earth's period of revolution around the Sun.

b) Jupiter has a longer period of revolution around the Sun than Earth.

Gravitational pull refers to the force of attraction that exists between any two objects with mass. The force of gravity is proportional to the masses of the objects and the distance between them. The greater the mass of an object, the stronger its gravitational pull, and the closer two objects are to each other, the stronger their gravitational pull is.

The gravitational pull of very massive objects, such as planets or stars, can be strong enough to affect the motions of other objects in their vicinity. For example, the gravitational pull of the Sun is what keeps the planets in our solar system in their orbits.

The correct answer is the frogs in the solitary contact area made an unmistakably distinctive call.

Hoskin and colleagues came to the conclusion that this new species was created through female choice since they were effectively cut off from neighbouring populations due to mating preference.

What is natural selection?

Darwin employed natural selection for the first time. He discussed the parallels and differences between the various creatures. These differences are sometimes referred to as variety. The process by which nature chooses the most adaptable and compatible organisms for evolution is known as natural selection. The organisms in nature face some difficulties. Climate change, food insecurity, and natural disasters including earthquakes, floods, and lightning are a few examples of these difficulties.

Most articles pass right through the atom, this means that most of the atom is an empty space.

An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.

Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.

As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

Light microscopy with the help of microscope will be used to view cells. It will not look the same as another animal from the ocean due to Bioluminescence.

What is the purpose of light microscopy?

By presenting a magnified image of how minute structures and samples interact with visible light, such as their absorption, reflection, and scattering, light microscopy is used to make them visible.

Light microscopes are employed for routine use when low magnification and resolution are sufficient as well as for the study of living cells. Higher magnifications and higher quality images are available with electron microscopes, but they cannot be utilized to see living cells.

Mutations are rare and can occur in body cells.

Mutations are changes in the DNA sequence of an organism.

They can occur in both body cells and reproductive cells, meaning they can be passed down from generation to generation.

Mutations can be beneficial, harmful, or have no effect on an organism's fitness.

While some mutations can lead to diseases, others can help an organism adapt to its environment or improve its chances of survival.

However, most mutations are rare and do not have a significant impact on the organism.

Therefore, it is not accurate to say that mutations are always harmful.

Germline mutations specifically occur in reproductive cells and can be passed down to offspring.

The cell membrane allows gases and nutrients in and out of the cell.

The correct answer is option D, the cell membrane. The cell membrane, also known as the plasma membrane, is a vital component of all cells. It serves as a selectively permeable barrier that separates the internal environment of the cell from its external surroundings. One of its crucial functions is to regulate the movement of substances in and out of the cell, including gases and nutrients.

The cell membrane is made up of a phospholipid bilayer embedded with various proteins. These proteins play a role in facilitating the transport of molecules across the membrane. There are two main types of transport across the cell membrane:

Passive Transport: This includes processes like diffusion and facilitated diffusion, where substances move from an area of higher concentration to an area of lower concentration. Small gases like oxygen and carbon dioxide can passively diffuse through the lipid bilayer of the membrane.

Active Transport: This involves the use of energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. Nutrients and other molecules can be actively transported using protein pumps.

In both cases, the cell membrane is responsible for controlling what enters and exits the cell, maintaining an appropriate internal environment for cellular functions. This selective permeability ensures that essential gases like oxygen and nutrients can enter the cell while waste products can exit. Thus, the cell membrane is a crucial structure that enables the exchange of gases and nutrients required for cellular metabolism and survival.
