The cell membrane contains channels and pumps that help move materials from one side to the other. What are these channels and pumps made of?

Group of answer choices


carbohydrates


proteins


lipids


nucleic acid

Answers

Answer:

The correct answer is ''proteins.''

Explanation:

Transport phenomena are essential in living beings, either to carry a hydrophobic molecule through an aqueous medium (transport of oxygen or lipids through the blood) or to transport polar molecules through hydrophobic barriers (transport through the cell membrane). Biological transporters are always proteins. Proteins are capable of carrying out specific functions such as the selective transport of molecules, or certain enzymatic reactions, among others. Membrane proteins can be peripheral or partially or totally integrated into the membrane, being, generally, globular or fibrous. Its activity is essential for the maintenance of transmembrane gradients. Thanks to membrane proteins, the exchange of molecules such as nutrients or waste products takes place, as well as the reception of external signals. Among its functions are channel-forming: Integral proteins arranged in the membrane in such a way that they give rise to the formation of a pore or channel, usually hydrophilic. These pores or channels allow the entry and exit of certain substances from the cell.

Since its inception, the theory of evolution has been the subject of frequent debate. Those who oppose evolutionary theory often point to gaps in the
fossil record in an attempt to discredit the theory. Which statement would be the best counterargument as to why the fossil record can be relied upon to
support evolution?
The fossil record provides evidence that extinct species only fossilized during certain geologic eras.
The fossil record provides evidence that extinct species are genetically identical to current species.
The fossil record provides evidence of many different types of organisms, since most species fossilize well.
The fossil record provides evidence of many transitional organisms that show relationships between species

Answers

Answer:

There are lots of transitional organisms in the fossil record though it does take very specific and precise conditions for a fossil to be preserved, a deer that dies in a field will not end up in the fossil record so we are looking at a small sampling of the evidence (and a good thing too or there wouldn't be anywhere to walk with all the bones laying around)

Select all that are true regarding ATP cycling


A. ATP is formed from ADP and phosphate

B. Energy for ATP synthesis comes from the oxidation of glucose and other fuel molecules

C. ATP hydrolysis is an endergonic reaction

D. Oxidation of ATP can be used for performing endergonic reactions in the cell

Answers

Answer:

A, B and D are correct

Explanation:

Adenosine diphosphate (ADP) can form a bond with a phosphate group to form Adenosine triphosphate (ATP), which is the most abundant energy carrier molecule in cells. An endergonic reaction is a chemical reaction where there is a net input of energy, while an exergonic reaction generates energy. ATP hydrolysis releases energy (conversely to ATP synthesis that requires an input of free energy), and therefore ATP hydrolysis is an exergonic reaction. ATP hydrolysis releases around 7.3 kilocalories per mole. In a coupled reaction, the energy released by ATP hydrolysis is used by the cell to carry out endergonic reactions in an exergonic manner (e.g., glucose phosphorylation, which is an energetically unfavorable reaction).

in fossils we see homologous structures that suggest a common ancestor.

By looking at the bones of the arms and comparative anatomy we see the similar structure and function that is retained.

When looking at other animals like birds we see Analogous structures that look similar but have a different function (flying).

Finally we see Vestigial structures which are structure that no longer function as they once were used for. An example of this is the coccyx (tail bone in humans) compared to tails in dogs, cats, monkeys, etc.

Crickets "chirp" by rubbing their wings or legs over each other. This phenomenon is known as stridulation. It is a means by which male crickets "call" to females to communicate their interest in mating. Frequency refers to the number of chirps that crickets produce during a period of time. Some have suggested that you can tell the temperature and the humidity based on how fast crickets chirp.

Required:
a. What is the effect of temperature on the frequency of cricket chirping? As the temperature rises, the cricket chirp occurs more rapidly therefore increasing.
b. What is the effect of humidity on the frequency of cricket chirping? As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing.

Answers

Answer:

a. As the temperature rises, the cricket chirp occurs more rapidly therefore increasing. It is correct.

b. As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing. It is incorrect. The increase in humidity does not affect the chirp frequency in crickets.

Explanation:

As temperature increases, the frequency of cricket chirp increases too. After listening to the audios, we can see that in the first audio, where the temperature is 14° Celcius, the frequency is 24 chirps in 15 seconds. In the second audio, with 19° Celcius, the frequency is 28 chirps in 15 seconds. In the last audio, where the temperature is 24° Celcius, the chirp's frequency is 34 chirps in 15 seconds. In conclusion, if the temperature increases, the chirps' frequency increases too.

As humidity increases, the frequency of the chirp does not. In the three audios, the number of chirps in 15 seconds was 20. We can conclude that humidity does not affect the frequency of chirps frequency.

Drosophila geneticists have isolated many mutations that modify position-effect variegation. Dominant suppressors of variegation [Su(var)s] cause less fre- quent inactivation of genes brought near heterochro- matin by chromosome rearrangements, while dominant enhancers of variegation [E(var)s] cause more frequent inactivation of such genes.
A. What effects would each of these two kinds of mutations have on position-effect variegation of the white gene in Drosophila (that is, would the eyes be more red or more white)?
B. Assuming that these Su(var) and E(var) mutations are loss-of-function (null) alleles in the corresponding genes, what kinds of proteins do you think these genes encode?

Answers

Answer:

A. As it is given that Su(var) dominant suppressors of variegation mutant allele causes lesser white patches and more red patches in eyes as it is an inhibits or inactivates of PEV. If the Drosophila were heterozygous for the dominant enhancers of variegation E(var) mutation, there would be less red patches and more white patches.

b. Su(var) 1 gene encodes for the proteins that assist in the spreading of heterochromatin by inhibits the PEV which will be lost by null mutations while E(var)1 gene encodes for the proteins that restrict the spreading of heterochromatin by loss of function mutation

Hello all. I really need help immediately with this question. Here is the question! Explain how these terms work together IN TRANSLATION: mRNA, tRNA, codon, amino acid, protein
Thank you sm for the help :)

Answers

Answer:

Translation takes place in 3 main steps: initiation, elongation and termination.

In initiation, the ribosome binds with the mRNA strand and a initiation complex forms. An initiator tRNA molecule brings the first amino acid, methionine. It binds with the start codon using its anticodon, UAC. The large ribosomal subunit then binds to the small ribosomal subunit.

In elongation, more charged tRNAs bring the amino acids to be added on the growing polypeptide chain. Elongation continues until the ribosome encounters the stop codon.

In termination, a release factor binds to the stop codon, causing the polypeptide to be released from the ribosome. The ribosomal subunits separate from the mRNA and from each other. The polypeptide undergoes folding to form secondary and tertiary structures to become a fully-functional protein.

Notes:

• Translation is the process by which a protein is synthesized from mRNA.

• mRNA: messenger RNA

• tRNA: transfer RNA

• codon: A 3-nucleotide sequence that codes for a specific amino acid. For example, AUG codes for methionine.
