What is the primary function of DNA replication in adult human somatic cells?
A to allow the cells to adapt to changes in the environment by generating new alleles of genes
B to generate multiple copies of genes the cell can use to increase protein production
c to prepare to create a new cell that contains the same genetic information
d to prepare the cell for meiosis to generate gametes
Answer:
B to generate multiple copies of genes the cell can use to increase protein production
Explanation:
Terms in this set (44) - Replication means that the DNA, with all its genes, must be copied every time a cell divides so that during growth and repair the newly formed cells have the correct genetic material.
Suggest what might happen if cells grow and reproduce in an environment where no cholesterol is available.
Cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis
Explanation:
If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.
What is plasma membrane?Cell membrane has been defined as a wall that differentiate and protect the inner structure of the cell from the outer environment. The main function of the cell membrane has to keep away the toxic material out of the cell. The cell membrane contain the channels as well as receptors that gives permission to only selective permeable membrane to enter into the cell.
Cells must maintain homeostasis to survive. To do this cells use various processes. One process keeps the right amount of water inside the cell. A cell takes in the same amount of water as it looses describe that it is maintaining homeostasis by keeping it's water concentration level.
Therefore, If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.

Determine the temperature of the bar on the fahrenheit scale.
Answer:
Determining bar temperature on Fahrenheit scale -
The temperature of the bar is given as 50 degrees Celsius.
If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.
We know
C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.
Now,
50/5 = (F-32) / 9
Or, (F-32) / 9 = 10
Or, F-32 = 90
Or, F = 90 + 32
Or, F = 112 degrees Fahrenheit.
That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit

What are the components of a multicellular organism?
Answer:
Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells.
Answer:
Because the first multicellular organisms were simple, soft organisms lacking bone, shell or other hard body parts.
What is gained from each part of aerobic respiration?
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. ... This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

How is it possible that the reactants and products for both chemical equations have the same quantity of carbon, hydrogen, and oxygen atoms, yet the reactants and products are different molecules?
Answer:
Yes, this may be a little confusing when taking a first glance at the chemical equation.
Explanation:
You see, the whole process of balancing an equation is to make sure the reactants and products have the same amount of mass/atoms.
With that being said, the products to appear to be different after going through the chemical change. this is because of what was happening through that process. But, all of these atoms are still within the final product.
For example, if you take water in a container, one with a lid and one without a lid, then you heat up both containers of water, the container that has the lid open will seem like the water is gone, that the atoms are not the same. Actually, if we take a look at the closed container, all of that gas that was formed from the water still has the same amount of atoms contained in it. As for the open lid container, the atoms are all there, but some of them was just released into the air outside of the jar, making it seem like there is less.

The study of chemicals is called chemistry.
It is possible to have different chemical properties but the same number of elements present in the reactant and the product.
According to the law of mass of conservation of the mass. it states that the number of elements present in the reactant and the product will always remain the same.
Hence, according to this law, the mass and the quantity of the element are the same but the bonds and the arrangement of the elements are different which causes different chemical behavior.
Hence, it is possible.

Explanation:
a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages
Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years

Sickle cell anemia is carried on the recessive allele. Normal is dominant. Mary is a carrier for sickle cell and Mike is normal (but not a carrier).
A. What are the chances of Mary and Mike having a sickle cell child?
B. What are the chances of them having a child who is a carrier?
Answer:
A. 0
B. 1/2 or 50%
Explanation:
Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.
Mary, a carrier would have the genotype Ss.
Mike, a perfectly normal person would have the genotype SS.
If both Mary and Mike marry:
Ss x SS
offspring: SS SS Ss Ss
(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.
(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.

An egg, a model of a cell, is placed in a concentrated sugar solution (hypertonic) for 24 hours.
What will happen to the egg? The egg will
1. lose mass and shrink in size
2. gain mass and increase in size.
3. stay the same mass and size.
Answer:
gain mass and increase in size
Answer:
1. lose mass and shrink in size
Explanation
the egg is a more dilute solution that the one it is placed in. Through osmosis it will lose water until both solution(the inside and outside of the egg) have roughly the same concentrations. Losing water will cause it to shrink.
