Answer:
The answers are DNA contains genetic material and X-ray diffraction.
Explanation:
For question 3 the answer is DNA contains genetic material!!
Hershey and Chase used radioactive isotopes to label a bacteriophage. ... After allowing the bacteriophage to infect the bacteria, the presence of radioactive phosphorus in the bacteria confirmed that DNA was the genetic material found in genes!!
For question number 4 the answer is X-ray diffraction!!
X-ray crystallography
Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule.

which is a biotic limiting factor that would influence the growth of a deer population?
A. amount of plant growth
B. high temperatures
C. amount of monthly rainfall
D. a Forest fire
Answer:
The answer would be "A"
Explanation:
A biotic limiting factor includes things like food, availability of mates, disease, and predators. Deer being herbivores, their food supply would be determined by plant growth.
Have a blessed day! Please mark brainliest if correct! :D
Number of plants is a biotic limiting factor that would influence the growth of a deer population. Temperature, rainfall, and forest fire are the abiotic factors which influence the population growth. Thus, the correct option is A.
What is Population growth?
Population growth is the increase in the number of organisms on Earth. For most of the organisms, population size was relatively stable. But with the change in the factors such as biotic factors and abiotic factors such as energy, food, water became more available and reliable.
The change in population size depends upon four main factors which are fertility rates, mortality rates, the initial age profile of the population and migration.
Therefore, the correct option is A.

What part of the rotifer is responsible for crushing food?
I said foot but I might be wrong. Help, anyone?
Answer:
Rotifers are specialists at living in habitats where water dries up regularly.
The Monogononta, which have males, produce fertilised 'resting eggs' which can resist desiccation (drought) for long periods.[11]
The Bdelloids, who have no males, contract into an inert form and lose almost all body water, a process known as cryptobiosis. Bdelloids can also survive the dry state for long periods: the longest well-documented dormancy is nine years. After they have dried, they may be revived by adding water. In this, and several other ways, they are a unique group of animals.[12]
Explanation:
The front has a ring of cilia circling the mouth. This gave the rotifers their old name of "wheel animalules". There is a protective lorica round its body, and a foot. Inside the lorica are the usual organs in miniturised form: a brain, an eye-spot, jaws, stomach, kidneys, urinary bladder.
Rotifers have a number of unusual features. Biologists suppose that these peculiarities are adaptations to their small size and the transient (fast changing) nature of its habitats.
Answer:
Trophi (got it right on my quiz)
Explanation:
The trophi located behind the rotifer's mouth are responsible for crushing food.

Why do you think mapping the bedbug genome may help scientists control pests?
Explanation:
When mapping the genome, it shows where other pests are more likely to appear. This means more control over the rate of pest growth, and they can stop reproduction from increasing.
Understanding the genome will enable scientists to know what traits the bug has and whether they have any resistance to insecticides. The bugs may have natural resistance to certain insecticides, but not to others. This research may help scientists develop effective insecticides.

what will happen to us if our body temperature fluctuate
Answer:
If the body temperature is too low, the enzymes in the body become inactive so many metabolic reactions cannot happen effectively, our metabolic rate will be affected, we may suffer from hypothermia.
If the temperature is higher than 37degree celsius, we will have a fever. But this actually allows enzymes to work at their optimum temperature, which speeds up the metabolic reactions in the body and is good for us.

Explanation:
ATP and ADP both play a role in cellular reactions involving energy. How are these two molecules related
Explanation:
If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. ... When it's run down, it's ADP.
ATP is converted into ADP and ADP can be changed back to ATP by the addition of a phosphate group.

You identify two different fish that you suspect are two different species. Design an experiment to test whether or not these fish are two different species AND how they became two different species. Be sure to explain how the results of your experiment would support your conclusion.
Answer: First, I would lay Out Both Fish, Identify ALL Differences - And Similarities Between Both Fish, Colors... Skin Material. Then Do as Much Re-Search Online. Find all Details About the Fish, Including They're Environments. (This came From My Mind... Hope its Right)
Explanation: Mark Brainlist Pleasee
Answer: I would first take samples of each fish to visually compare physical traits. Assuming this could be a type of speciation, I would research the differences within their shared environment such as food sources, habitat locations, mating rituals, and foraging preferences. Online I would research histories for reproductive isolation, monophyletic groupings, and the absence of allopatric divergence. To prove my theories, I would take several local random samples of the same two species and collect all types of shared trait data. Based on the data gathered, I would determine whether it was likely that they are related.

HELP ASAPPP Why can insertions and deletions affect more than just the codon(s) that they directly change? Hint: Why are they called frame-shift mutations?
Answer:
Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions, and deletions are usually more harmful than a substitution in which only a single amino acid is altered.

How many membranes cover the Golgi apparatus?
Answer:
The Golgi apparatus (GA), also called Golgi body or Golgi complex and found universally in both plant and animal cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons.
Explanation:
The Golgi apparatus is a series of membranes shaped like pancakes. The single membrane is similar to the cell membrane in that it has two layers. The membrane surrounds an area of fluid where the complex molecules (proteins, sugars, enzymes) are stored and changed.
Answer:
3 to 8 membranes called cisternae
