If the area had experienced a wet season two years after the drought instead of a dry season,
what kind of evolution would you expect? Explain your answer.
Answers
The organisms will start adaptation to that environment in order to survive.
If the area had experienced a wet season for two years after the drought instead of a dry season then we expect that the organisms that lives in that environment will start adaptation to that humid environment in order to survive.
What is adaptation?Adaptation occurs when an organism adapts certain actions to a certain environment in order to live more comfortable. If the organism do not adopt certain features then it will be extinct from that environment while on the other hand, those organism which adopt certain features will be able to survive so we can conclude that the organisms will start adaptation to that environment in order to survive.

a bacterium is infected with an experimentally constructed bacteriophage
Answers
The complete question is:
a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have
A) T2 protein and T4 DNA
B) T2 protein and T2 DNA
C) a mixture of DNA and proteins of both phages.
D) T4 protein and T4 DNA
E) T4 protein and T2 DNA
A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.
A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.
The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria. Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.
In conclusion, The new phages produced would have D) T4 protein and T4 DNA.

What happens when an action potential is produced with a signal that is stronger than threshold?
A)
weaker action potential generated
B)
no action potential generated
C)
action potential has same strength as threshold
D)
stronger action potential generated
Answers
Answer:
C) action potential has same strength as threshold
Explanation:
What happens when an action potential is produced with a signal that is stronger than threshold action potential has same strength as threshold
When an action potential is produced with a signal that is stronger than the threshold, the resulting action potential is typically stronger or more intense compared to a standard action potential. The answer is D) Stronger action potential generated.
The threshold is the minimum level of depolarization required to initiate an action potential in a neuron. If the signal surpasses the threshold, it means that the depolarization is greater than what is necessary to trigger the action potential.
When a stronger signal is received by the neuron, it results in a larger influx of ions (such as sodium) into the neuron, leading to a more pronounced depolarization of the cell membrane.
As a result, the action potential generated will have a higher amplitude or voltage compared to a regular action potential. Therefore, the answer is D) Stronger action potential generated.

what molecule makes instructions for proteins and is located inside a eukaryotic nucleus
Answers
Answer:
DNA stores that info
Explanation:
In eukaryotic cells (ex. plants and animals) the DNA is found in the nucleus of the cell. Structures called ribosomes build proteins (this process is called translation).
The molecule that is responsible for carrying the instructions for the formation of protein is mRNA, which is formed inside the nucleus.
The mRNA is known as the messenger RNA because it acts as a messenger, to carry the instructions required to create a polypeptide chain.
The mRNA is formed during the process known as transcription. The mRNA is formed by the molecule known as RNA polymerase.
During the process of transcription, the genetic information gets copied as a strand of nucleotides containing adenine, uracil, guanine, and cytosine, known as mRNA, which is formed inside the nucleus.
The molecule which act as a carrier of the genetic information for the formation of proteins is known as mRNA.

Answers
The homologous structure to the forearm of humans is the leg of the horse.
What are homologous organs?Homologous organs are organs that share similar structural organization. They are similar structurally but are different in functions. They share common ancestors. These organs are anatomically similar. As there are common ancestors, this type of evolution is known as divergent evolution.
The reason behind the divergent evolution is environmental changes, and food requirements which force them to evolve according to the requirements. The wings of bats, the forearms of humans, and the front legs of the horse are a few examples of homologous organs which underwent divergent evolution.

regulation of the cell cycle is dependent on cyclins and cyclin-dependent kinases. the key that allows a cell to progress beyond the restriction point is
Answers
The key that allows a cell to progress beyond the restriction point is the phosphorylation of specific proteins (for example RB) by Cdk. The cyclin-dependent kinases (CDKs) are able to phosphorylate different substrates.
Cyclins regulate the progression of the cell cycle by their interaction with cyclin-dependent kinases (Cdks).
This binding activates the Cdks, thereby converting them into functional enzymes that phosphorylate target proteins and thus regulate cell cycle progression by bypassing restriction points of the cell cycle.
CDKs can phosphorylate different substrates by transferring phosphate groups from adenosine triphosphate (ATP) to specific amino acidic residues in these substrates.
For example, CDKs phosphorylate Rb proteins and thus regulate their activity during the cell cycle.
