Group of answer choices
It helps to control what substances move in and out of the cell.
It makes the cell membrane more rigid.
It helps the cell to keep its shape.
It helps keep proteins out of the cell.
Answer:
It helps to control what substances move in and out of the cell.
Explanation:
Phospholipid bilayers are critical components of cell membranes. The lipid bilayer acts as a barrier to the passage of molecules and ions into and out of the cell. However, an important function of the cell membrane is to allow selective passage of certain substances into and out of cells. This is accomplished by the embedding of various protein molecules in and through the lipid bilayer. These proteins form channels through which certain specific ions and molecules are able to move. Many membrane proteins also contain attached carbohydrates on the outside of the lipid bilayer, allowing it to form hydrogen bonds with water.

Put the steps of transcription in order
The complementary RNA nucleotides are added.
RNA polymerase binds to the promoter.
DNA strands are unwound and separated
Answer:
1. RNA polymerase binds to the promoter.
2. DNA strands are unwound and separated
3. The complementary RNA nucleotides are added.
Take a look at the attached picture. First, the RNA polymerase must bind to the promoter region to initiate the whole process. DNA must be unwound by DNA helicase, then it will make the RNA transcript, which consists of adding the complementary RNA nucleotides to the DNA strand. Then the transcript leaves the nucleus and begins translation.
DNA strands are unwound and separated, RNA polymerase binds to the promoter, and the complementary RNA nucleotides are added. These are the steps of transcription in order.
What is transcription?Transcription is the process by which RNA molecules are synthesized from DNA templates. The first step in transcription is the unwinding and separation of the DNA double helix by an enzyme called RNA polymerase.
The enzyme binds to the DNA template strand separating the two strands and DNA template strand is further used for RNA synthesis, while the other strand is the non-template or coding strand. RNA polymerase then binds to the promoter region of the DNA template strand which is located at the start site of transcription.
After the binding, a complementary RNA starts synthesizing using the DNA template strand by adding complementary RNA nucleotides. As the RNA polymerase moves along the DNA template strand, RNA molecule starts growing which is complementary to the DNA template strand. This step is followed by elongation and termination of growing RNA molecule.
Therefore, transcription steps include DNA strands are unwound and separated, RNA polymerase binds to the promoter, and the complementary RNA nucleotides are added.

A male giraffe has 31 chromosomes in each of its sex cells. How many would be present in its body cells?
Answer:
62 chromosomes.
Explanation:
Sex cells are formed undergoing meiosis, which means that they contain a haploid number of chromosomes. (Half the number that somatic/body cells contain). 31 is half of 62, which means that the diploid number of chromosomes in the body cells of a giraffe would be 62.

Where does the stench come from the is in your arms?
Answer:
The human armpit has a lot to offer bacteria. It's moist, it's warm, and it's usually dark. But when the bacteria show up, they can make a stink. That's because when some kinds of bacteria encounter sweat they produce smelly compounds, transforming the armpit from a neutral oasis to the mothership of body odor.
Explanation:
Body odor is caused by bacteria breaking down sweat and is largely linked to the apocrine glands. ... They are scent glands. The apocrine glands are mainly responsible for body odor because the sweat they produce is high in protein, which bacteria can break down easily.

Answer:
cnidarians
Explanation:
bryozoan - "Bryozoa are a phylum of aquatic invertebrate animals. Typically about 0.5 millimetres long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia." -Wikipedia
rotifers - "The rotifers, commonly called wheel animals or wheel animalcules, make up a phylum of microscopic and near-microscopic pseudocoelomate animals." -Wikipedia
cnidarians - "Cnidaria is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments: they are predominantly marine. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick.
" -Wikipedia
mollusks - "Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda. The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high." -Wikipedia

describe the benefits and drawbacks of experiments in a laboratory compared with experiments in a natural setting
Answer:
Experimental set up in the lab.are under the control of the scientist,therefore they can manoeuvre the the surrounding conditions to suit the experimental set up for best results. In addition the lab.environment does not involve the complex interactions or reaction between the set up and the lab. environments, compare to the natural environment.
Natural experimental set up gives accurate results from the interaction of the organisms(e.g animals) under investigation in the natural environments,thus the results obtained are natural interaction of the organisms based on the environmental factors the organism are exposed to.However, the number of organisms are usually large,and therefore great effort is needed to determine the actual cause and effects of the factors affecting the organisms under investigations in this natural environments.
A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type of
limiting factor causes this?
Odensity dependent
Odensity independent
O population dependent
population independent
Answer:
density independent
Explanation:
In Ecology, a limiting factor refers to an environmental condition that hinders the growth and distribution of organisms in an ECOSYSTEM. A limiting factor hinders or hampers the productivity of an organism in its habitat.
There are two major types of limiting factors that affect organisms in their ecosystem viz: density dependent and density independent limiting factors. Density independent factor limits the size of a population independently of how dense the ecosystem's population is. This means that density independent factor affects a population irrespective of its size. Example of density independent factor are natural disasters e.g earthquake, hurricane, forest fire as mentioned in the question.
In this question, both populations of trees and birds are affected irrespective of the size of the ecosystem's population.

Why is water pollution a concern if water is continuously cycled through Earth’s systems?
Water pollution is still a concern, even though its cycled through the Earth's system continuously, for many reasons. Firstly, people still continue to dump toxic chemicals, and plastic/ garbage into the water. Plastic doesn't decompose, it continues to sit and pollute the ocean unless it is cleaned up. Then there are also the chemicals. Some of these chemicals don't dissipate, or clear out for many years. There is also oil that has been spilt into the ocean. Even though it was many years ago, it still lingers in the ocean, and is very difficult to clean up. Secondly, there are bacteria and algae that lives in the water, which makes it very harmful for us if not cleaned out. The Earth's system is unable to keep these organisms out of the water. Thirdly, there is constantly water, even though water goes through the cycle, there is still unfiltered polluted water that stays, and then pollutes the filtered water.
