What do cells want to being in and what do cells want to keep out

Answers

Answer 1

Answer:

Cell membranes serve as barriers and gatekeepers. ... Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.

How does latitude affect a climate zone?

A. Climate zones at high latitudes are cooler because they are closer to the equator.
B. Climate zones at high latitudes receive a lot of precipitation because they are farther C. from the equator.
D. Climate zones at low latitudes receive little precipitation because they are closer to the ocean.

Answers

None of the options is entirely correct about latitude and climate zone.

Latitude and climate zone

Latitude is one of the main factors that affect climate, along with elevation, ocean currents, and prevailing winds.

Generally, the farther away from the equator a location is, the colder its climate is. This is because the angle of the sun's rays hitting the Earth's surface is more oblique at higher latitudes, resulting in less heat being delivered per unit of surface area.

However, precipitation patterns are not solely determined by latitude. They are also affected by other factors such as prevailing winds, ocean currents, and topography. For example, areas located on the windward side of a mountain range tend to receive more precipitation than those on the leeward side, regardless of their latitude.

Therefore, while latitude is an important factor in determining climate zones, it does not fully determine precipitation patterns or temperature.

Answers

Answer:

churning of the stomach contents.

Explanation:

When food is moved to the back of the mouth by the tongue (deglutition), it does not cause the churning of the stomach contents.

The churning of stomach contents occurs when the bolus from the mouth has entered through the lower esophageal sphincter into the stomach. Churning is the mixing of the bolus with digestive juices containing acids and enzymes secreted from the stomach lining.

Which of the following functions do Golgi bodies provide for the cell?


Help maintain cellular shape

Direct all cellular activities and act as the brain of the cell


Assist in the early stages of protein and lipid production

Answers

The Golgi body assist in the early stages of protein and lipid production

The function that the Golgi bodies provide for the cell is that they assist in the early stages of protein and lipid production. The correct option is D.

What are Golgi bodies?

The Golgi apparatus is basically an organelle encountered in most eukaryotic cells. It is also referred to as the Golgi complex, Golgi body, or simply the Golgi.

It is a component of the cytoplasmic endomembrane system that packages proteins into membrane-bound vesicles before they are transported to their destination.

Proteins produced by ribosomes in the ER are packed in the Golgi apparatus, where lipids wrap them in a membrane that is then exported from cells.

Molecules entering the Golgi are charged, stored, and then released back into the cytoplasm (secretory vesicles).

The Golgi bodies function in the cell by assisting in the early stages of protein and lipid production.

Thus, the correct option is D.

"What if speciation occurred in humans?" Your essay should give a clear and precise example of speciation.
A student is asked to write an essay over the hypothetic prompt above. While brainstorming, the student came up with
four different ideas for their essay. Which idea is BEST aligned with the writing prompt and instructions?

Answers

The term speciation refers to the process by which two or more different species are produced from a single original population by different speciation mechanisms. Speciation occurs in three main steps: separation of the original population, divergence (trophic divergence, reproductive divergence, genetic divergence, etcetera), and isolation.

The most related option to speciation is  B. Two populations of humans living on separate sides of the ocean. After a catastrophic event, travel across the ocean is not possible. After millions of years of separation, the two groups are no longer able to produce viable offspring together, but can still produce within their isolated groups.

Speciation occurs when the original population is divided into two groups.  They inhabit different places and are exposed to varying environmental conditions. With time, each group experience many genetic changes. These mutations depend on each group´s environment and its ecological pressures, and they accumulate in time. Pressures act on individuals and make them adapt to the new environmental conditions. Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce. Fixation of mutations will increase the difference between the two groups, up to the diverging point into two new species. Even is they get together again, these species will not be able to mate and produce offspring, and if they do, the new generations will not be viable or fertile.

The exposed case of two human population living on different sides of the ocean, is an example of allopatric speciation.

Allopatric speciation refers to the geographic separation of a continuous genetic background, originating two or more new geographically isolated groups. During these events of speciation, emerging new barriers impede genetic flow between groups, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.  

Different stages are involved in the allopatric speciation process:

• The emergence of the barrier.  

Interruption in the genetic flow

Slow and gradual differentiation due to the occurrence of mutations in each population and their accumulation in time.  

Genetic divergence by natural selection and reproductive isolation,  impeding the two groups to mate even if the barrier disappears.  

Prezigotic isolation mechanisms favored by selection a secondary contact between the new species occurs.
