VikaD [51]

Answer:

- Organism A is most likely a herbivore

- Organism B is most likey a carnivore

Explanation:

Based on feeding habit, organisms, usually animals, can be classified into three categories namely: herbivores, carnivores and omnivores.

- Herbivores are those organisms that feed on vegetative matter i.e. plants while carnivores are those organisms that feed on flesh of other animals or organisms. Based on what they feed on, herbivores are adapted to possess blunt teeth (for chewing) like Organism A in this question while carnivores are adapted to possess sharp teeth (for tearing flesh) like Organism B.

Based on the above explanation, organism A is most likely a HERBIVORE while organisms B is most likely a CARNIVORE.

- Another notable point of difference between herbivores and carnivores, which is likely to differentiate organism A and B as well, is that herbivores possess digestive enzyme- amylase in their saliva while carnivores do not. Herbivores need AMYLASE to break down complex carbohydrate (starch) in the plants they feed on.

1. Most familiar life forms live in regions of biomes that humans inhabit. (1 point)

Genrish500 [490]

Answer:

1. The first statement is true. A biome is defined as a large set of naturally occurring plants and animals occupying a major habitat. For e.g. forest, dessert, grasslands etc.

2. The given statement is True. Biodiversity is defined as the variety of plants and animals exists or existed in the world or in any specific habitat. The high level of biodiversity is important and beneficial for the environment.

3. This statement is False. Outside force such as earthquake, zone hole etc can certainly cause changes in the organism. For example, UV rays can cause cancer in an organism, dark colorization of peppered moth during industrial revolution.

4. It is True as species is defined as a group of organisms capable of interbreed and share common characteristics. It is the basic unit of biological classification. For example, sapiens is the species of human being.

5. Yes, the given statement is true. Charles Robert Darwin famous naturalist, biologist, and geologist. He was best known for his work in the field of evolution and gave the theory of natural selection. He is also known as the father of evolution.

6. No, all scientists were not agreed with Charles Darwin, for example, Lamarck, Weismann etc. However, Neo-Darwinism was much more accepted that Darwin original theory. Hence, the given statement is false.

7. Natural selection is one of the process of evolution. It sates that organisms better suited and adapted to their environment have better chances of survival. Organisms acquire new characteristics over the generations in order to adapt in a environment. Hence, the given statement is false.

8. The statement is true. However, recently it has been found that there are some bacteria which can inhabit the extreme conditions. They are known as extremophiles, for example, halophiles, thermophiles etc.

9. Yes the statement is true. These organisms are known as extremophiles, for example, halophiles (which live in high saline conditions), thermophiles (can live in high temperatures) etc.

10. This statement is false as there are many species which have not been discovered yet.

Scientists say the planet Venus has a "runaway greenhouse effect." What condition would you expect on Venus as the result of a r

Inessa05 [86]

Answer:

I think the answer is

D. The planet is extremely hot.

Explanation:

It's because there is no water left on the surface, which helps cooling down the planet and the atmosphere contains thick and excessive carbon dioxide which traps the heat, causing the planet to heat up.

How do volcanoes form at A?

zlopas [31]

At the place marked with the letter A we have a divergent plate boundary. On this type of boundary, the plates are moving away from one another. As they move away, they leave a gap behind them, and the crust is becoming thinner and thinner with lots of cracks in it. Because of that, the high pressures from the mantle manage to push upwards the magma with ease. The magma reaches the seafloor and it is pushing the crust upwards until it breaks it. As the magma pushes the crust upwards,underwater volcanoes are formed, and when the crust is broken by the magma, the magma flows get on the seafloor, cool of very quickly in the water, and create new crust.

What allows for some substances to be reabsorbed and others to leak from the tubule in the enthrone?

MAXImum [283]

The right answer is A) semi-permeable membrane

A semi-permeable membrane is a membrane permeable to a liquid (solvent) and impermeable (or poorly permeable) to substances dissolved in the liquid (solute).

The tubule of a kidney consists of a semi-permeable membrane and has also specific transporters which allow absorption and reabsorption. These "tools" allows some substances like ions to be absorbed/reabsorbed (by the transporters), without any changes in the concentration of the other substances (because both the membrane and the transporters stopped them).
