Which of the following contributes to Mars’ cool temperatures? this is for astronomy.

pochemuha

The answer that contributes to Mars's cool temperatures is the third choice - Its thin atmosphere and distance from the Sun.
Mars is relatively distant from the Sun - it is the fourth planet away from the Sun which means that it can be quite cold there given that its atmosphere is quite thin which means that the cold is quite present there.

How much fossil fuel is used in your home? Also, make recommendations about how to reduce your usage.

nikdorinn [45]

Answer:

To reduce the amout you can go all solar powered to power your house. Fossil fuel is used to make heat. But now days most homes in the United States Of America use solar power or get electricity from wind mills.

Explain the role of lipids, carbohydrates, and proteins in the cell membrane.

koban [17]

Lipids provide structure - allow the selective diffusion. Proteins provide structure - involved transport - involved in cell adhesion. Carbohydrates are involved in cell recognition - receptor complexes.

<h3>What is the function of lipids, carbohydrates, and proteins in the cell membrane?</h3>

The cell membrane is composed of a lipidic bilayer, cholesterol, proteins, and glucans incrusted in between.

⇒ Lipids

Phospholipids are amphipathic molecules.

They have hydrophilic heads facing the exterior and the interior of the cells and hydrophobic tails that arrange against each other in the interlayer space.

Lipids can easily change places with other lipids by lateral diffusion and transversal diffusion.

Their function is to provide structure to the membrane and allow the diffusion of some selected small molecules.

⇒ Cholesterol

These lipidic molecules play a significant role in membrane formation and structure. They are embedded in the membrane in between phospholipidic tails.

⇒ Carbohydrates

Carbohydrates are significant energy store molecules.

Carbohydrates get attached to lipids and proteins on the outer side of the membrane (glycolipids and glycoproteins).

Complexes protein-carbohydrate are used to identify and differentiate the cell and work as receptors.

Carbohydrates are also involved in cell adhesion.

⇒ Proteins

Among the proteins, we can find integral proteins and peripheric proteins.

Integral proteins are permanently associated with the membrane. They accomplish many different functions such as substances transport, cellular receptors, and cellular adhesion, among others.

According to how they are incrusted in the lipidic bilayer, integral proteins might be,

→ Transmembrane proteins ⇒ they cross the two lipid layers of the cell membrane.

→ Monotypic integral proteins ⇒ they can be found tied to one of the lipidic layers.

Integral proteins provide structure to the plasmatic membrane.

Periferic proteins are in the internal or external surface but not incrusted in the membrane.

In conlusion,

Phospholipids are the basic elements of the cell membrane. They are arranged in two layers, and thanks to their motion properties, they allow passive transport (diffusion) of some substances.

Proteins provide structure, are involved in facilitated and active transport, and are involved in cell adhesion.

Carbohydrates are involved in cell recognition and in receptor complexes.

Select the two correct statements. Select the two correct statements. All proteins will show different degrees of divergence bec

nalin [4]

Complete question:

Comparisons of amino acid sequences can shed light on the evolutionary divergence of related species. If you were comparing two living species, would you expect all proteins to show the same degree of divergence? Select the two correct statements.

All proteins will show the same degree of divergence because they are modified with the same rate of evolution.
All proteins will show the same degree of divergence because different species experience the same selection pressure.
All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.
All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.
All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.
All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism.

Answer:

3) All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.

4) All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.

Explanation:

All proteins will show the same degree of divergence because they are modified with the same rate of evolution. FALSE.
All proteins will show the same degree of divergence because different species experience the same selection pressure. FALSE
All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure. TRUE
All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. TRUE
All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism. FALSE
All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism. FALSE.

In this example, we are comparing different species, although we do not know how different they are. Changes in the proteins reflect the divergence between groups during evolution. Among different animals and plants, changes in proteins and their following maintenance can be associated with a group divergence and evolution.

The same proteins amino acid sequences in different species provide information about the divergence point between both species. Probably, the origin of genes and protein changes and the subsequent fixation of those changes by natural selection is the cause of most of the phenotypic variation observed between species. So, genes and proteins are subdued to selective pressures that vary according to the environment and the species.

In populations of the same species inhabiting different places with different environmental characteristics suffer changes that respond to their life habits. Proteins evolve in different degrees and take different routes, influenced by the selective pressures of the environment surrounding them. Ecological, behavioral, reproductive pressures, among others, vary between populations according to their own needs and produce changes that "model" the organisms when fixating. These changes are inherited generation after generation, leading to a divergence in the species.

How does the hydrosphere affect the atmosphere?

horrorfan [7]

Answer:

so when pure water vapor from the water bodies get absorbed into polluted gases in the atmosphere, acid rain is caused and when this happens in a place where an element of the hydrosphere is located, it is polluted.
