Can you tell me about cellular respiration and photosynthesis? I do not understand.
Answer:
Photosynthesis is the process in which plants make their on food; Cellular respiration is the process through which cells convert sugars into energy.
Explanation:
Answer:
the job of photosynthesis is to turn energy from the sun into chemical energy that can be used for food. Cellular respiration is the cycle that occurs in the mitochondria of organisms to break down sugar in the presence of oxygen to release energy
Explanation:
proteins regulate cell process, transport substances into or out of cells, and help
a. regulate blood pressure
b. form bones and muscles
c. control body temperature
d. regulate pH in various parts of the body
Answer:
B
Explanation:
I think it's B since proteins don't control blood pressure or temperature. Also I'm pretty sure they don't regulate the body's PH

natural selection is an example of a mechanism of evolution. does this mechanism produce a change in individuals or population? explain
Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.

A hurricane passes through the Gulf of Mexico and destroys many of the coastal regions of Northwest Florida,
Which of the following is a likely impact of this catastrophic event on biodiversity?
Species brought in by the storm surge will displace species native to the coastal wetlands.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity
will increase in these areas.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the
local species, causing a decrease in biodiversity
Answer:
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.

Explain how different forms of a gene are distributed to
offspring.
Answer: During gamete formation, the alleles for each gene segregate from each other, so that each gamete carries only one allele for each gene. an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles.
What are genes?
Genes are an basic physical and functional unit of heredity.Genes are what make our DNA.

all living things are classified into kingdoms based on specific characteristics. which of the following are only characteristics to the bacteria domain
Answer:
Eukaryotic cell, cell wall made of cellulose present
Explanation:
took the test
The main characteristics of the bacteria domain is that they lack a well-defined nucleus and are known as prokaryotes.
What is the main characteristic of the bacteria domain?All living things are classified into kingdoms based on specific characteristics found in organisms in that kingdom.
For the bacteria kingdom, the main characteristic present is that they lack a well defined nucleus as well as nuclear membrane.
Organisms without a well-defined nucleus are known as prokaryoytes.
Thus, the main characteristics of the bacteria domain is that they lack a well-defined nucleus and are known as prokaryotes.

Explanation:
A man with blood group B marries with a woman with blood group AB and the daughter has blood group AB. Is this information enough to tell you which of the traits – blood group B or AB is dominant? Why or why not?
Answer:
YES. This information is enough to assume that neither of the blood groups dominates over the other one.
Explanation:
Available data:
A man with blood group B ----> Genotype IBIB or IBiA woman with blood group AB ---> Genotype IAIBTheir daughter has blood group AB --> Genotype IAIBThe fact that the daughter´s genotype is IAIB tells us that she got the IA allele from the mother, who is IAIB, and the IB allele from his father, who is IB-.
If blood type B was dominant over A or AB, then the daughter should have Blood type B. If blood type A was dominant over B or AB, then the daughter should have Blood type A. Blood type AB tells us that both types are being expressed, A and B.The fact that the daughter inherited one type of allele from each parent, but she is expressing the blood type AB, suggests that neither of the alleles dominates the other one. This is an example of co-dominance, where the heterozygote phenotype is an additive expression of both of the parents' genes.
This is enough information to assume that neither of the blood groups dominates over the other one.

EXPLAIN HOW A DEER TICK COULD INFECT YOU WITHOUT YOU REALIZING IT
Answer:
Because ticks stay attached to hosts, blood feeding for several days, they secrete novel pain killers, called kininases, in their saliva which help them go unnoticed. If you have been bitten previously, you may notice a small red bite mark, which can be itchy.
Explanation:
Answer:
The deer tick is tiny, no larger than a pencil point.
Explanation:
Most tick bites are harmless and don't need medical treatment. But some ticks (like the deer tick, wood tick, and others) can carry harmful germs that cause diseases like Rocky Mountain spotted fever and Lyme disease. The deer tick is tiny, no larger than a pencil point. Which mean it could bite you without you realizing it.

A kid on a trampoline has 1,000 J of potential energy when they are at the top of a jump. How much kinetic energy will the kid have when they come halfway down?
A. 100 J
B. 250 J
C. 500 J
D. 1000 J
Answer:
C. 500 J
Explanation:
Given;
potential energy of the kids at the top of the trampoline, P.E = 1,000 J
⇒At the top of the trampoline, the kids have only potential energy.
⇒On half way down, the kids have both kinetic energy and potential energy.
⇒At the bottom of the trampoline, the kids have only kinetic energy.
Based on the statements above, the kinetic energy of the kids half way down is calculate as;
P.E + K.E = 1000 J
Base on law of conservation of energy, P.E = K.E
2 K.E = 1000 J
K.E = ¹/₂ x 1000 J
K.E = 500 J.
