Answer:

Proteins are responsible for shaping and growth of an organism.

Explanation:

The differences in proteins lead to different in traits because it is the protein that determines the trait. The gene's sequence is like language that instructs cell to manufacture a particular protein that is necessary for the growth and development of the organism. These proteins shaped the structure of organisms so we can say that difference in traits occur due to difference in their proteins.

Answer:

This question lacks options, the options are:

A) An mRNA molecule is produced in the nucleus of the cell.

B) The ribosome attaches to the DNA to build a polypeptide

C) The resulting RNA molecule is a complement of the gene on the DNA.

D) The RNA molecules contains three nucleotides in a row whose bases form

a codon.

E) A polypeptide is synthesized based on the sequence of nucleotides on the tRNA molecule.

The answers are A, C and D

Explanation:

Transcription is the first process of gene expression whereby a mRNA is synthesized from a DNA template. Transcription, which occurs in the NUCLEUS, takes place in three stages namely: initiation, elongation and termination.

- Initiation involves the attachment of RNA polymerase to the DNA molecule, inducing the unzipping of the double stranded DNA.

- Elongation involves the synthesis of RNA strand by adding complementary nucleotides based on the ones read on the DNA strand.

- Termination signals the end of the transcription process.

Based on this question and the above explanation of the transcription process, the following pertains to transcription in the nucleus:

- mRNA molecule is produced in the nucleus of the cell.

- The resulting RNA molecule is a complement of the gene on the DNA.

- RNA molecules contains three nucleotides in a row whose bases form a codon.

Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.

This story showed an example of convergent evolution. Convergent evolution is the process whereby organisms that are not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

In this story, the two species of birds, the crows and the jays, evolved to look similar as a result of living in the same environment and competing for the same resources.

The two species evolved to look similar in order to blend in with their environment, making it difficult for predators to distinguish them from one another. This allowed them to survive and thrive in the same environment.

Therefore, This example of convergent evolution is a perfect example of how species can evolve to look similar in order to survive in the same environment. It also shows how competition for resources can drive species to evolve similar traits in order to survive.

Answer:

The asteroid crashed into the earth and made some water bodies violent

it is said that the asteroid was super huge and was capable of causing volcanoes, tsunamis, etc which took place all over the earth and extincted dinosours. But it is a little surprising that crocodiles who were also found at that time survived all this

Answer:

Probably the asteroid caused natural calamities

Cells require a structure that regulates the transfer of material in and out of the cell, and this structure is the cell plasma membrane, as substances can go in or out of the cell such as oxygen, water, etc.

The cell plasma membrane's purpose is to protect the cell from outside materials such as matrix proteins, pathogens, and so on, as well as to give the cell the proper shape and size, and at the same time it consists of many channels, pumps, etc. Through the channels, the substance can flow in and out of the cell plasma membrane, and the energy may or may not be needed for the movement.

Hence, cells require a structure that regulates the transfer of material in and out of the cell, and this structure is the cell plasma membrane, as substances can go in or out of the cell such as oxygen, water, etc.

Hello. This question is incomplete. The full question is:

A student prepared two beakers with identical sprigs of a water plant as shown below. She placed Beaker A in the shade and the Beaker B beside a fluorescent lamp. She then systematically changed the distance from the beaker to the lamp. She counted the bubbles given off by the plants in each beaker.  

If the student later tested the bubbles collected in the test tube, What would she find they are made of?

Answer:

oxygen

Explanation:

The bubbles are oxygen and we can say that because this is the gas that plants release through photosynthesis. In this case, we can also confirm that the plant that was exposed to fluorescent light, showed more bubbles than the other plant, since the light allowed the photosynthetic rate of this plant to be higher, releasing more oxygen to the environment.

Answer: Plant cells only have chloroplast and a cell wall. Which is A and E.

Answer:

Dominant: the genes that are expressed/ shown

Recessive: the "hidden" genes

Explanation:

If one parent has a dominant gene for brown eyes and the other has a recessive gene for blue eyes, then the offspring will have brown eyes.

Hope this helps!

You can message me if you are still confused.

Explanation:

dominant genes will always appear before recessive ones, in order for recessive genes to appear, both copies of the gene have to be the recessive one tldr for this paragraph, think of dominant genes like jackets, and recessive ones like t shirts

an example

B=brown hair gene (dominant)

b=blond hair gene (recessive)

this is an example of 2 parents, with offspring

Bb Bb <-- both parents have a copy of brown and blond hair gene, but since dominant genes appear before recessive ones, they both have brown hair

now, lets look at their possible offspring genes

BB Bb Bb bb

in order, their hair color will be

brown, brown, brown, blond

see the last one? the only reason why that child is blond is because they don't have a brown hair gene tldr of this paragraph, recessive genes will only be present if both copies of the gene is the same

with the first example, lets say its a cold day. what would you wear, a jacket or a t shirt? a jacket, obviously

but what if you only had t shirts? then you would be forced to wear that and think about your poor freezing self...

pretend the T shirt is blond hair gene, and jacket is brown hair

and the closet only holds 2 clothes

2 domiant genes will do the same thing, brown hair

1 domiant gene and 1 recessive will use the domiant gene, since domiant genes get used first, like brown hair will show even though you have a copy of blond hair gene

2 recessive genes, and only then will the recessive show, like blond hair

Well for the onion peel, since its a plant cell...it shall gain water from the solution as it has a lower water potentail,and hence increase in size, becoming turgid and tight, with the cell wall exerting pressure to stop it from bursting.

For the RBC, its an animal cell, and shall also gain water, but since there is no cell wall to support it, it shall soon gain so much water that it shall burst becuase of the pressure, through lysis, and shall die.

Note, the plant cell does not die.

DNA is approximately six times longer than it is wide after measurements.

DNA is a 2-nanometer-diameter double-stranded molecule. Rise per base pair is 0.34 nanometers. Divide length by width to calculate length-to-width ratio. The length-to-width ratio is 6:1 due to DNA's stable diameter and base pair distance. DNA is six times longer than broad.

DNA stores and encodes genetic information efficiently in this elongated shape. DNA molecules can range from a few hundred base pairs in bacterial genomes to millions or billions in sophisticated animals. DNA stores and transmits life's genetic blueprints because it's longer than it is wide.

Answer:

Explanation:

By maintaining amount of ions in the blood.

Countercurrent flow met the goals due to difference in concentration gradient.

Explanation:

Diffusion restored homeostasis during the dialysis treatment because during dialysis, the concentration of ion in the blood is maintained that leads to homeostasis.

Countercurrent flow met the goals because it flows in opposite direction while on the other hand, parallel flow did not meet the goals because it flows in the same direction. For example. the blood flows in one direction and the dialysate flows in the opposite direction. The countercurrent flow of the blood and dialysate increases the concentration gradient between the blood and dialysate. The increased gradient helps to remove more potassium, phosphorus and urea from the blood. If we used parallel flow so less  concentration gradient of solutes is present and hence, less potassium, phosphorus and urea are removed from the blood

Hope it helps you!!!

Answer:

See the answer below

Explanation:

Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways

Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat

Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.
