4. Why does cell division take place in single celled organisms?
A In order for organisms to grow
B.te reproduce and pass along genetic information
C.to enable the organisms to heal injured tissues
D.to make specialized cells for different functions
Answer:
A) In order for organisms to grow.
Explanation:
Tell me if I am wrong. I hope this helps :)
Cell division in a cell takes place in the single-celled organisms to reproduce and pass along the genetic information of the cell. Thus, the correct option is B.
What is Cell division?Cell division is the process of division of cell through which a parent cell divides into two daughter cells with equal genetic content which are similar to the parent cell. Cell division generally occurs as a part of a larger cell cycle in which the cell grows in size and the cell replicates the chromosomal material before it is undergoing cell division.
In the unicellular organisms, cellular division is a significant process through which a unicellular organism undergoes development and result into the formation of a new organism with genetic material which is similar to the parent cell. In the multicellular organisms, process of cellular division helps in maintaining a balance between the genetic material such as the DNA and the RNA contents as well as the nuclear and cytoplasmic contents of the cell.
Therefore, the correct option is B.

One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don't soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.

1. Consider the following food chain.
grass
deer
wolf
If the deer population increases, explain what could happen to the grass population
Most likely the grass population will decrease and the wolf population will increase.
Eventually it should level out again though.
If the population of deer will increase will result in the decrease in grass quantity.
What is a food chain?A food chain is a linear network of links in a food web that begins with producer organisms and ends with an predator, detritivores, or decomposer species.
A food chain also shows how organisms are related to one another through the food they consume. Each extent of a food chain represents a distinct trophic level.
Overgrazing occurs when there are too many deer in a given area, resulting in the loss of brush and shrubs in forested areas. The absence of undergrowth means that small animals and birds have no place to shelter and nest.
As a result, many native species are becoming extinct because they no longer have access to the habitat they require.
Thus, the grass population will decrease as a result of increase in deer population.

Describe the ways mutations can affect DNA and chromosomes.
The mutation affects DNA and chromosomes by changes in the sequence of DNA or changes in the gene present on the chromosome.
What is mutation?The mutation is a sudden change in the structure of chromosomes or DNA. The smaller mutation affects the nucleotide base in DNA, while the larger mutation affects the genes present on the chromosomes.
The substance which causes mutation is known as mutagens. Mutation can cause problems in growth and development and affects the functioning of the body. When changes occur in chromosomes or DNA, they cause changes in the protein. Due to this, a different kind of protein is produced.
The mutation is caused by the insertion, duplication, deletion, and substitutions of a DNA sequence. Thus, mutation can affect DNA and chromosome in many ways.

A student performed an experiment by placing the de shelled egg in a concentrated salt solution for 5 minutes.What changes did he observe in the egg?Name the process
Answer:
the egg begins to shrink
Explanation:
During the 5 minutes that the egg is in the concentrated salt solution he would notice that the egg begins to shrink. This occurs due to the process known as osmosis which happens when a solvent passes a semipermeable membrane towards where there is a higher concentration which in this case would be within the egg. Since the egg would contain more water than the salt solution causing it to shrivel and shrink.

Suppose you are determining the growth rate of two species of plants. Species A is 25 cm tall and grows 3 cm per month. Species B is 10 cm tall and grows 8 cm per month. Which system of equations models the height of each species H(d) as a function of days d. H(d) = 25 + 3d H(d) = 10 + 8d H(d) = 3 + 25d H(d) = 8 + 10d H(d) = 25 + 3d H(d) = 8 + 10d H(d) = 2 + 8d H(d) = 25 + 10d
Answer:
H(A) = 25 + 3m and H(B) = 10 + 8m
Explanation:
Let H(A) is the height of species A as a function of months m while H(B) is height of species B as a function of months m.
For Species A,
H(A) = 25 + 3m
For species B,
H(B) = 10 + 8m
Hence, this is the required solution.
Which goes where ? Mitosis Vs. Meiosis
Answer:
Mitosis, Meiosis, and both are written below
Explanation:
Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas
This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages
This is because meiosis occurs in gametes and is used in reproduction.Both: Chromosomes need to replicate before the whole process begins, a form of reproduction
This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.If a female fruit fly heterozygous for red eyes (X RX r) crossed with a white-eyed male (X rY), what percent of their offspring would have white eyes? (Draw a Punnett Square.)
Answer:
6.25%
Explanation:
Given that:
The trait of a female fruit fly that is heterozygous for red eyes = XRXr; &
The trait of a white-eyed male is XrY_ ;
since Y is dominant y; the male trait can either be XrYR or XrYr
So, let assume that it is XrYr
Then; if each trait self crossed; we have:
XRXr = XX Xr XR Rr
XrYr = XY Xr rY rr
Thus, the punnet Square can be computed as:
XX Xr XR Rr
XY XXXY XXYr XXYR XRYr
Xr XXXr XXrr XXRr XRrr
rY XrYX XxYr XrYR RrYr
rr XrXr Xrrr XrRr Rrrr
∴
the percentage of offspring that would have white eyes XrY_ is:
1/16 = 0.0625
= 6.25%
Regulation of body temperature in humans is most closely associated with the
A) production of gametes
B) evaporation of sweat
C) absorption of carbon dioxide
D) production of hydrolytic enzymes
Answer:
b
Explanation:
Regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.
What is the need for homeostasis in the body?The body maintains a particular internal temperature irrespective of changes in the external environment, and this is possible because of the homeostasis in the body, which is important because many of the body's processes are temperature and pH sensitive, such as the enzymatic function, the alkalinity of blood, etc.
Hence, regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.

11. How has our misguided, or inappropriate, use of antibiotics led to the development of organisms like
MRSA and VRSA?
Answer:
1. use of the wrong antibiotic
2. use of insufficient concentration of the right antibiotic
Explanation:
MRSA means Methicillin-resistant staphylococcus aureus
VRSA means Vancomycin-resistant Staphylococcus aureus
These are resistant forms of the bacteria Staphylococcus aureus to the antibiotics mentioned.
Bacterial resistance to antibiotics occurs when bacteria develop mechanisms that protect them against the effects of previously effective antibiotics.
Misguided and inappropriate use of antibiotics results in resistance, and they mainly occur as a result of two activities:
1. Use of wrong antibiotics: antibiotics are chosen using a microbiological technique called 'sensitivity testing', to determine which antibiotic is effective against a bacterium. However, when antibiotics are taken without proper sensitivity testing, the bacteria develop resistance against such antibiotics.
2. Use of inadequate concentration of the right antibiotic: This involves using less than the minimum inhibitory of minimum bactericidal concentration of an antibiotic against a bacteria. In this case, the organism has ample time to evolve in the presence of the antibiotic, hence the occurrence of resistance.
