Answer:
The surface area to volume ratio (SA:V) limits cell size because the bigger the cell gets, the less surface area it has for its size.
Explanation:
This is important if you are a cell that depends on diffusion through your cell wall to obtain oxygen, water, and food and get rid of carbon dioxide and waste materials.

Which of the following is the major concern with utilizing forensic DNA testing?
O keeping Innocent people out of all
treating genetic diseases as early as possible
a violation of privacy
a violation of the law
Answer: a violation of privacy
Explanation:
A person's DNA cannot be changed as it is their genetic information. It is therefore their most private information and when it is utilized in forensic DNA testing, it runs the risk of invading a person's privacy.
Forensic DNA testing works by comparing the subject DNA with a DNA database. Using this database means going through the DNA of millions of people without their consent.
This is their most private information and it is being stored and accessed without permission. Critics say that this is a violation of privacy and many studies have showed that this is a major concern

important?
Because it increases the genetic variability, offering more combinations of genotypes.
what conditions can cause a population to decrease?
Answer:
if the population is too high and food is scarce.
high population attract predators.
high competition for food.
mutations.
Answer:
A reduction over time in a region's population can be caused by sudden adverse events such as outbursts of infectious disease, famine, and war or by long-term trends, for example sub-replacement fertility, persistently low birth rates, high mortality rates, and continued emigration.
Monitoring levels of which two gases would help determine the human
impact on air quality?
A. Methane
B. Water vapor
C. Carbon dioxide
D. Oxygen
Answer:
A. Methane
C. Carbon dioxide
Explanation:
Methane and carbondioxide are the two gases that determine the human impact on air quality because these gases are produced due to human activities. Methane gas is used in homes for cooking and heating purpose while on the other hand, carbondioxide gas is released from burning of fossil fuels in the engine of vehicles and industries for making different products. These two gases greatly affect air quality.

How does the mitotic spindle ensure that each daughter cell receives a full complement of the genetic material in the cell nucleus
Answer:
The mitotic spindle attaches to the kinetochores at the centromeres of the chromosomes and then it moves toward the poles of the cell. Thus, sister chromatids are separated simultaneously at their centromeres so that each daughter cell will have the same genetic material as the parent cell (i.e., daughter cells will be genetically identical to the parent cell).
Explanation:
The mitotic spindle is a structure composed of microtubule proteins whose function is to ensure the correct segregation of the chromosomes during mitosis. During metaphase, microtubules from the mitotic spindle bind to the kinetochore (a protein complex assembled on the centromeric region) in order to align sister chromatids on the metaphase plate. Subsequently, during anaphase, the mitotic spindle moves toward the poles of the cell, thereby sister chromatids are separated from each other. In consequence, each daughter cell will have the same amount of genetic material (i.e., the same number of chromosomes) as the parent cell.
What is the after effect of increased temperature in the atmosphere?
Answer:
global warming
Explanation:
The body layers that can be dissected in the dissection study area are arranged from superficial to deep.
True or False
Answer:
True
Explanation:
The correct option about the arrangement of the body layers to be dissected in a dissection study from superficial to deep is ; TRUE
During dissection study there only one way in which structures can be viewed also when the body layers are to be dissected are arranged in only one way as well ( from superficial to deep ) because the superficial layers lie just under the skin while deep layers lies deep inside the skin surrounding each muscle.
therefore arranging the body layers from superficial to deep is the best arrangement when dissecting.

Citrus trees create their seed by a method of asexual reproduction by a process called
Answer:
Some plants can produce seeds without fertilization. Either the ovule or part of the ovary, which is diploid in nature, gives rise to a new seed. This method of reproduction is known as apomixis. An advantage of asexual reproduction is that the resulting plant will reach maturity faster.
Explanation:
Answer:
Apomixis
Explanation:
Apomixis is the method of asexual reproduction.

Which of the following are pyrimidine?
A. Guanine and cytosine
B. Thymine and Guanine
C. Cytosine and uracil
D. Guanine and adenine
E. Adenine and thymine
Answer:
c.Cytosine and uracil
Explanation:
Two types of Nitrogenous bases(heterocyclic aromatic molecules) are found in DNA and RNA: 1.Pyrimidines and 2.Purines
Pyrimidines:Thymine(5-methyl-2,4-dioxypyrimidine) and Cytosine(2-oxy-4-aminopyrimidine) are found in DNA . Uracil (2,4-dioxypyrimidine) and Cytosine (2-oxy-4-aminopyrimidine) are found in RNA.
Purines:Adenine (6-aminopurine) and Guanine(6-oxy-2-aminopurine) are the two purine bases that are found in both DNA and RNA.
When shorthorn red cattle are bred to shorthorn white cattle, they produce roan (red and white hairs interspersed) offspring. What type of inheritance is this
Answer:
Co-dominance.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.
This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.
In this scenario, when shorthorn red cattle are bred to shorthorn white cattle, they produce roan (red and white hairs interspersed) offspring. Therefore, this type of inheritance is known as co-dominance because the two (2) alleles (shorthorn red and shorthorn white) are expressed equally or simultaneously in their offspring i.e a roan.

ecosystem?
O Organisms that depend on insects may not survive, eventually harming all the organisms that are interconnected.
O The biodiversity of the ecosystem cannot be protected by laws unless there are a certain number of insect
species.
O There will likely be fewer insects that harm plants, causing an increase in plant diversity.
O Having fewer insects allows other organisms to use the resources that the insects were using.

2. Based on your results, can any conclusions be draw as to the types of habitats likely to contain the most microbes?
Answer:
Yes.
Explanation:
Yes, conclusions can be drawn from the types of habitats the most microbes likely to present because different microbes needs different types of environmental conditions. Some microbes needs moist and cool environment and can't survive in warm and dry environment while some microbes survive in dry and warm environment and die in moist and cool environment so we can draw conclusion from their habitat types.
