A sperm cell moves its flagella back and forth in order to move through its environment. Which statement describes how this euka

ryotic cell transfers energy to the flagellum in order to allow it to move?
A The cell uses photosynthesis to make the glucose needed to create ATP.
B The cell uses the mitochondria to generate high energy proteins that move the flagella.
C The cell produces ATP in the mitochondria and the high energy bonds are used to move the flagella.

How is a forest ecosystem more stable than a cornfield?
kobusy [5.1K]
A forest typically has a water source, with other natural occurring things where as a corn field doesn't have a lot of protective things. Like a forest has a bigger food chain where a cornfield mostly has mice and snakes and that's it. A forest just has more things to help it thrive

describe the goals of maximum sustainable yield management, ecosystem based management, and adaptive management. list a drawback
Crank

In this question we will describe the management goals of maximum sustainable yield, ecosystem-based management and adaptive management.

<h3>What is a sustainable management plan?</h3>

A sustainable management plan aims to maximize forest production and minimize damage to the remnant responsible for the productive, structural, functional and genetic support of the exploited forest.

<h3>What is ecosystem-based adaptation?</h3>

Ecosystem-based adaptation protects vulnerable communities from extreme weather while providing a variety of crucial benefits for human well-being, such as clean water and food.

<h3>What is Adaptive Management?</h3>

Adaptive Management is a management approach developed to provide organizational systems with a greater degree of adaptability, seeking to provide means to increase the speed of response to environmental pressures and improve the quality of this response.

With this information, we can conclude that the disadvantages of these methods are that they will bring harm to the affected ecosystem.

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.

Blood plasma is filtered in the __________.
ziro4ka [17]

The Kidneys.

The plasma passes through the kidney where it is filtered, a special filtration unit called "glomeruli" and then excreted as a low molecular weighted product into the urine. The purpose of our urine is to secrete waste products from the body. So you can see how the glomerular filtration mechanism of the kidneys plays a major role in the function of our bodies. The primary function of our kidneys is to filter out all the "bad stuff" in lamest terms.

What does a S-shaped curve demonstrate for population growth?
11111nata11111 [884]

A design of growth in which (occurs only in a different situation), the population frequency of an organism rises gradually originally, in a good acceleration time, later progresses swiftly nearing an exponential growth pace just like the J-shaped curve, however, it later declines (meaning rejects) in a bad acceleration time till at zero growth rate the population maintains. For example, yeast is a tiny fungus, so tiny, a microscope is required to view it, furthermore, it is used to produce bread and alcoholic drinks, displays the traditional S-shaped curve if raised in a test tube. Its maturity levels off as the population deplete the nutrients that are essential for its growth.
