A cell with two pairs of each set of chromosomes is called a diploid cell. These cells are typically found throughout the body tissues and are called [ germ / somatic ] cells.
Answer:
somatic
Explanation:
Explain at least three ways in which a mutation in an individual's DNA could occur, and describe at least 2 effects a mutation could have on an individual's traits
Answer:
Mutations can occur from the following ways:
1. Errors that occur in DNA replication during cell division
2. Exposure to high-energy electromagnetic radiation
3. Exposure to chemicals mutagens
Effects of mutation include:
1. Genetic disorders
2. Cancers
Explanation:
A mutation is a change or alteration that occurs in the DNA sequence of a cell of an organism. These mutations can be passed on to offsprings of that organism. Mutations can occur from the following ways:
1. Errors that occur in DNA replication during cell division: during the process of cell division, the DNA in cell are copied many times. Some errors result when copying DNA, most of which are corrected during proofreading. However, some changes in the DNA sequence may not be corrected, thus resulting in a mutation.
2. Exposure to high-energy electromagnetic radiation: some types of electromagnetic radiation are ionizing, such as UV rays and X-rays. Prolonged exposure to these ionizing radiation may result in permanent damage to parts of the DNA, thereby resulting in a mutation.
3. Exposure to chemicals mutagens: mutagens are substances which are able to cause mutations. Some common chemical mutagens are alkylating agents such as ethylmethane sulfonate and N-methyl-N-nitrosourea.
Effects of mutation include:
1. Genetic disorders: in genetic disorders, certain normal functioning of the body processes are impaired. For example, hemophilia whereby blood lacks the ability to clot normally resulting in excessive bleeding.
2. Cancers: cancers occur when the cell of the body differentiate and grow abnormally. Various types of cancers include breast cancer, prostrate cancer, blood cancer etc.
Which of the following substances is responsible for transporting materials into and out of the cell by active transport? A. Carbohydrates B. Proteins C. Cholesterol D. Lipids
Identify the type of mutation that occurred and explain in what way it affected the protien
Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.

What is Chargaff's Rule?
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

A. competition
B. predation
C. human disturbances
D. immigration
Answer: I think it is d
Among the given options, immigration is considered as the limiting factor to a population. Thus, the correct option is D.
What is Population?A Population may be defined as the number of individuals of the same species living in a particular area at a definite time. It also represents the number of males and females in any population with respect to their characteristics.
Competition, predation, and human disturbances are responsible for the reduction of any population. This is because these factors generally involve the ultimate death of individual and health damage.
While immigration is typically a process through which an individual has come in order to live in that place. This place is not native to the individual. This increases the population of any specific region.
Therefore, among the given options, immigration is considered as the limiting factor to a population. Thus, the correct option is D.

When electrons transfer from one atom to another, both atoms become Choose... and they are held together by a(n) Choose... bond. When electrons are shared between atoms, a(n) Choose... bond forms between the atoms, and the joined atoms become a(n) Choose... .
Answer:
This question is incomplete as it lacks a word bank, the word bank are:
Ions
Electrons
Isotopes
Molecules
Covalent
Negative
Ionic
Molecular
Hydrogen
Point
Element
Ionic compound
The answer is:
1. Ions
2. Ionic
3. Covalent
4. Molecule
Explanation:
An ION is a charged atom i.e. an atom with positive (+) or negative (-) charge, which results when an atom loses or gains electrons respectively. The ions of different elements are held together by bonds called IONIC BONDS, which are bonds that form as a result of the difference in electric charges or electrostatic forces between the atoms involved. For example, an ionic bond forms between NaCl because there is an electrostatic force between the positive Na+ ions and negative Cl- ions.
However, on the contrary, when electrons are shared between atoms, a COVALENT BOND is formed. The atoms share their valence electrons to form a MOLECULE, which comprises of two atoms.
HIV can remain latent for several years and not cause any symptoms in its host. What viral reproduction cycle is occurring during this latency period? What viral reproduction cycle is occurring once a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection?
Answer:
The lytic cycle.
Explanation:
HIV is a retrovirus that has a special enzyme called transcriptase reverse, which can synthesize DNA using RNA as a template. This replication system is particularly useful for the virus because the DNA synthesized from the RNA viral genome can be then integrated into the human chromosomes and stay inactive for years. This is called a lysogenic cycle and is characterized by a latency of the virus and an integration to the host DNA.
When there is a triggering event, this latent virus can be excised from the human chromosome and start producing copies of itself using the host machinery. Then the virions are assembled and after that they lyse the host cell and release new infective units that can then infect neighboring cells. This is called the lytic cycle of the virus and is the reproduction cycle that occurs when a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection.

If researchers use only the number of coral found in dive 1, calculate the predicted population of brain coral in a reef that covers 120m squared. i forgot how to do this :))
Answer:
40
Explanation:
Each quadrant measured = 2m X 2m
Length = (2+2+2) m = 6m
Width = 2m
Total area = area of (quadrant 1 + quadrant 2 + quadrant 3)
Total area = 6 * 2 = 12 m^2
Number of coral found in dive 1 = 4
Population density = 4/12 = 1/3 (0.33)
Now,
=> Population density = (Predicted population)/area
=> 1/3 = PP/120
=> PP = 120/3 = 40
So, the required answer is 40.
The predicted population of brain coral in a reef covering 120m² is ; ≈ 40
First step : Calculate the value of the default population density
Population density = population size (dive 1) / total area
= 4 / 12 = 0.33
Total area ;
∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²
∴ Total area = 4 + 4 + 4 = 12m².
Final step : Determine the value of the predicted population of brain coral
Population density = ( predicted population ) / predicted area
0.33 = ( pp ) / 120m²
∴ Predicted population ( pp ) = 0.33 * 120
= 39.6 ≈ 40 brain corals
Hence we can conclude that the predicted population of brain coral is 40

The top of the saturated zone is known as A. the aquifer B. the water table C. the unsaturated zone D. spring rock
Answer:
B. the water table
Explanation:
The question above is related to the topic on "Groundwater."
Groundwater is considered "fresh." It falls into the soil and gets soaked in it. It can stay stored for many years. It is very beneficial because it serves as a source of water for many residential places.
The storage of groundwater relies on two zones: unsaturated zone and saturated zone. The unsaturated zone is the first layer under the surface area of the land. It is followed by the "water table," which lies a little farther from the land surface. After which is the saturated zone where you can find particles of different rocks.
The top of the saturated zone is known as the water table. Therefore, option (B) is correct.
The water table divides the saturated zone, where water fills the crevices between soil or rock particles, from the unsaturated zone, which is air-filled. Precipitation, groundwater exploitation, and seasonality affect the water table. It controls groundwater supply and flow.
Spring or surface water bodies can form where the water table meets the land. Managing water supplies, analysing groundwater flow patterns, and assessing groundwater contamination require water table monitoring.
