list two functional difference between plant and animal
Answer:
A plant cell is larger than an animal cell. The shape of a plant cell is a fixed rectangular shape, whereas an animal cell is mostly round and irregular in shape. Plant cells store energy in the form of scratch while animal cells store energy in the form of complex carbohydrates and glycogen.

How does antibody specificity arise
Answer:
The specificity of the immune system arises from its antigenic receptors such as antibodies present on the B-cells. ... It was earlier perceived that each antibody is capable of binding specifically with one unique epitope through the antigen-binding site present on the variable region of the antibody

What items are used to identify the genetic makeup of an unknown organism?
Answer:
Polymerase chain reaction machine
Primers
Petri dishes
Test tubes
Pipettes
DNA Polymerase
Free nucleotides
The organism to be identified
Explanation:
To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.
To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.

QUESTION 2 (ENZYME ACTIVITY]
The investigation was carried out to determine the effect of a detergent containing fat-
digesting enzymes on a fat stain.
The procedure was as follows:
Two identical cloths were used
Cloths A and B had identical fat stains.
Cloth A was washed using a detergent not containing fat-digesting enzymes for five
minutes at 37°C.
Cloth B was washed using a detergent containing fat-digesting enzymes for five minutes
at 37°C.
Answer:
Explanation:
Why are enzymes added to washing powder, and how do they work? Carry out some simple experiments to investigate this further. ... pepsin, a digestive enzyme in the stomach, works best at pH 2. ... People have been experimenting with ways to use the power of enzymes to clean clothing for a long time
As mentioned in the video, Dr. Nachman and his colleagues have collected dark and light colored mice from dark and light colored rocks in other areas of the American Southwest and found similar patterns (i.e., dark colored mice were more likely to be found on dark rocks; light colored mice were more likely to be found on light rocks). However, genetic analysis showed that the dark fur color in other rock pocket mouse populations was caused by mutations in different genes. This means that there is more than one way (genetically speaking) to make a mouse dark. It also means that adaptive mouse coloration has occurred more than once in similar environments across the southwestern US. How does this information support the concept that natural selection is not a random process
Complete question:
In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.
How does this study support the concept that natural selection is not random?
Answer:
The study supports the concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.
Explanation:
All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. They can do it by having a similar fur color that the color of the rocks they live on. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.

Can genetic engineering cause harm to humans?
Answer:
There are many risks involved in genetic engineering. The release of genetically altered organisms in the environment can increase human suffering, decrease animal welfare, and lead to ecological disasters. The containment of biotechnological material in laboratories and industrial plants contributes to the risk of accidental release, especially if the handling and storage are inadequate.

How does natural selection lead to changes in organisms?
Answer:
it is every organisms goal to "survive and repopulate" therefore, with natural selection the weaker organisms die because they did not possess the traits necessary to survive, and the strong survive and repopulate
Explanation:
list two functional difference between plant and animal
Plants:-
# They are autotrophs (prepare their own food)
# They won't have locomotion for walk.
Animals:-
# They are heterotrophs (depends upon others for food).
# They have locomotion for walking purpose.
Why is genetic variation among individuals beneficial?(1 point)
A) More genetic variation means higher rate of survival versus species that have less genetic variation.
B) Genetic variation staves off extinction because it creates a fit population.
C) Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.
D) Genetic variation leads to more new traits in the population which means evolution can occur faster.
Answer:
Some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.
Explanation:
it was the correct answer from the test
Genetic variations may lead to the diversity in the phenotypes of surviving individuals. It reduces the chances of extinction.
What do you mean by Genetic variations?Genetic variations may be defined as the presence of differences in sequences of genes between individual organisms of a species.
Genetic variation among individuals is beneficial because some individuals will have inherited traits that give them a competitive advantage that make them more likely to survive and reproduce.
Therefore, it is discussed above that genetic variation among individuals is beneficial.

Mr. Yien reports to the clinic after having passed reddish- colored urine this morning. He reports that he has been feeling very fatigued for several weeks and hasn't been urinating as much as usual. He also tells you that three years ago he had a kidney transplant. You order a urinalysis, which is positive for large amounts of blood and protein. What is potentially causing Mr. Yien's problems, given his medical history? Explain.
Answer:
Kidneys typically don't permit giant proteins to go through them. however thanks to harm to the units of excretory organ (nephrons), these proteins go through kidneys and ar suffered excretory product. This sickness is named symptom.

discuss the importance of Animal behavior?
Answer:
Animal behavior is the bridge between the molecular and physiological aspects of biology and the ecological. Behavior is the link between organisms and environment and between the nervous system, and the ecosystem. Behavior is one of the most important properties of animal life. Behavior plays a critical role in biological adaptations.
