The correct option is B. It regulates body temperature.

<h3>What is homeostasis?</h3>

In biology, homeostasis is the condition of steady internal, physical, and chemical requirements maintained by living systems.

  • This is the requirement of optimal functioning for the organism and contains many variables, such as body temperature and fluid balance, being kept within certain pre-set limitations (homeostatic range).
  • Other variables include the pH of extracellular fluid, the engagements of sodium, potassium, and calcium ions, as competently as the blood sugar level, and these need to be regulated despite changes in the atmosphere, diet, or level of activity. Each of these variables is controlled by one or better controllers or homeostatic mechanisms, which together maintain life.
  • Homeostasis exist obtained about by a natural resistance to switch when already in the optimal conditions, and balance is maintained by many regulatory mechanisms.
  • All homeostatic control mechanisms include at least three interdependent elements for the variable being regulated: a receptor, a control center, and an effector.

imagine a cell-surface receptor protein is being newly synthesized. How can it get into the membrane that it will ultimately be
motikmotik

Answer:

the steps for a new receptor synthesis:

Explanation:

Do not forget the steps vary from an eukarityc cell to prokarityc one.  

IN AN EUKARYOTIC CELL:

1- Transcription: in the nucleus, mRNA is synthesized from the DNA sequence that codifies the protein. Exons are spliced if needed by spliceosomes.  

2- From nucleus into cytoplasm: mRNA goes through nuclear membrane into the cytoplasm were ribosomes, substrates for protein synthesis and other organelles are.

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)  

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- (The mRNA has a signal that is recognized by the rough endoplasmic reticulum) The peptide goes into this reticulum (RER) and then into Golgi apparatus. (more chemical modifications are made if needed). By this moment the protein has an inserted portion in a lipid membrane.

6- The protein is transported in a vessel that finally fusions with cytoplasmic membrane and the receptor is in destiny. Hydrophobic aminoacid sequences are inserted in membrane.

IN A PROKARYTIC CELL:

1- Transcription (no splicing is needed, there are not exons)

2- There are not nucleus and cytoplasm divided (no transport)

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- The mRNA has a signal that is guides the growing protein to cellular membrane. Hydrophobic aminoacid sequences are inserted in membrane.

Which step in the PCR program would you have to change if your fragment would have been 10 times longer and how?
bekas [8.4K]

Answer:

increasing extension time

Explanation:

The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.

Cilia:
Alexxx [7]

Answer:

E. All the answer options are correct.

Explanation:

Cilia are very small hair-like, membrane-bound cell structures. They are present on the surface of many eukaryotic cells. They are made of microtubules and are continuous with the plasma membrane of a cell. On a single cell, they are present in large numbers as compared to flagella. The major function of cilia is to move the cell or to move substances such as mucous, fluid over or around the cell.

What is the effect of soil salinization on crops?
matrenka [14]

Answer:

Salinity affects production in crops, pastures and trees by interfering with nitrogen uptake, reducing growth and stopping plant reproduction. Some ions (particularly chloride) are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies.

Describe the factors that influence the development and type of soil in a certain area.
arsen [322]

Soil research has shown that soil profiles are influenced by five separate, yet interacting, factors: parent material, climate, topography, organisms, and time. Soil scientists call these the factors of soil formation
