How can an organism's environment affect its traits?
First, I read that so incorrectly. Awkward.
An organism's environment affects its physical and self traits by making them adapt. Charles Darwin had discovered this theory with the finches. Places that were harder to get food would make these finches physical change over evolution to help them survive. It changes the animals habits depending on their resources. If a bird eats berries but there is no berries then the bird will have to change its diet or it will die.

Explanation:
It is less than 1.4 million years old
Based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.
What do you mean by Fossils?Fossils may be defined as the dead and organic remains of the past organisms which are preserved deep in the soil over a long period ago.
The fossil found in area A is very recent from the evolution point of view. The deeper the layer, the oldest is the fossil.
Area A of the fossil is synthesized after the time period of 1.4 million years ago, hence the fossil present in that area would be less than 1.4 million years old.
Therefore, based on the absolute dating of the rock layers in this photograph, a scientist could conclude about a fossil found in area A is that it is less than 1.4 million years old.

A geneticist is trying to recreate a strand of DNA from a crime scene investigation. The strand of DNA recovered from the scene was 1800 bases long. The geneticist has determined that the strand contained 425 thymine
nucleotides. Based on this information, identify the number of cytosine nucleotides
Answer:
475
Explanation:
The strand is only made up of Adenine, Thymine, Cytosine and Guanine. There will be the same number of Adenine as there are Thymine and the same number of Cytosine as there are Guanine.
We know there are 425 Thymine. This means there are also 425 Adenine. Therefore, you would subtract 850 (425x2) from 1800 to find the amount of Cytosine and Guanine left, which is 950.
Out of the 950, half will be Cytosine and half Guanine. 950/2 is 475.
The cell cycle is disrupted when there is an abnormal increase in the rate of mitosis. An
abnormal and uncontrolled increase in the rate of mitosis is frequently associated with an
individual developing
A. O a type of cancer.
B.
into two or more organisms.
C.
only one sex cell.
D.
a single set of chromosomes.
Answer:
A
Explanation:
Cancer is the uncontrolled increase of cells, so when the rate of mitosis increases, so does the number of cells. This means A is the answer.
Uncontrolled cell growth is cancer. Gene mutations can increase the pace of cell division or suppress natural mechanisms that keep the body in check, like cell cycle arrest or programmed cell death. Thus, option A is correct.
What results, uncontrolled increase in the rate of mitosis?The cell's size, the presence of neighboring cells, and other chemical stimulators are three of the key elements in mitotic regulation.
Numerous mitogens are involved in regulating mitosis. Therefore, cell size, cell existence, and chemical stimulators are the proper answers.
When cancer cells develop in body tissues, they undergo aberrant cell growth patterns known as hyperplasia and dysplasia.
An increase in the quantity of cells in an organ or tissue that look normal under a microscope is known as hyperplasia.
Therefore, An abnormal and uncontrolled increase in the rate of mitosis is frequently associated with an individual developing cancers.

Which statements are true about this sequence?
Select all that apply.
Protein synthesis cannot start because there is no start codon.
The protein will have only four amino acids.
Two methionine amino acids will be in the protein chain.
The protein will have five amino acids.
Answer:
The correct answer is -
Two methionine amino acids will be in the protein chain.
The protein will have five amino acids.
Explanation:
In protein synthesis, there are mRNA codons made up of the three bases known as triplet codons that form a specific amino acid during translation. There is a specific codon known as the starting codon that is AUG present at the beginning of almost every protein sequence and code for the methionine amino acid. UAG, UGA, and UAA are the stop codons if present at the end of the mRNA sequence and if any of these stop codons are present at the end of the sequence they do not produce any amino acid.
In this case, the mRNA sequence having 6 triplet codons AUG CCC UUU AUG GGG UAA where the first AUG is a start codon and code for the methionine and UAA is a stop codon and do not code for any amino acid therefore, the protein would carry only 5 amino acid and as there are two AUG so it has two methionine.
Answer:
Two methionine amino acids will be in the protein chain.
The protein will have five amino acids.

advantages and dis advantages of asexual reproduction in plants
Explanation:
Advantages Of the asexual reproduction
The organism that reproduces asexually has the ability to take many different extensive forms that allow asexual reproduction to succeed in various environments?
The asexual reproduction is only performed in the organisms that often stay in one place, It does not need mobility, So, most plants have a great ability to create their offspring as this process doesn’t need to move to another place.
Asexual reproduction has a rapid increase of offspring which is very helpful in producing lots of offspring, It lets the plants make lots of offspring effectively which will help them in increasing their genes.
Disadvantages Of Asexual Reproduction
Most organisms that only perform the asexual reproduction process have less chance to adapt to the changes of the environment as they need stable environments.
Only one parent plant is required for the asexual reproduction, the new plants are identical to the parent so that good features will always be passed on, the chromosomes and genes of the parent will be copied, So, there will be genetic defects or the mutation in the offspring with no exception.
The asexual reproduction does not have the genetic diversity, there is less variation produced with the offspring, and the organism becomes less adapted to certain environmental changes, the entire communities will not be adapted to the harsh environment.
The asexual reproduction usually leads to struggle for the existence as well as the overcrowding, and the main distinction of asexual reproduction from the sexual reproduction is that there is no need for two parents as well as special cells to reproduce.

viral diseases only
any infectious disease
Any infectious disease (genetic, bacterial, and viral) can be prevented by vaccinations. Therefore, option D is correct.
Vaccinations are primarily designed to stimulate the immune system and provide protection against specific pathogens that cause diseases. They work by introducing harmless components of the pathogen, such as inactivated or weakened viruses or bacteria, or their components (antigens), into the body.
This exposure allows the immune system to recognize and mount an immune response against the pathogen without causing the actual disease.
