a human cell contains a very limited number of genes?
Answer:
False
Explanation:
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.
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.

does addiction contribute to martial problems?
Yes or No? and why?
Answer:
Yes. It contributes to marital problems because for example lets say you have a husband that is addicted to alcohol he is going to spend hundreds of dollars on alcohol every month and you are eventually going to get tired of not having enough money to pay the bills and get groceries. If your husband doesn't get rehab if will eventually get worse & rehab also costs money. Nobody will want to put up with that. Another example is if your husband is addicted to gambling your money is going to go down the drain very quickly leaving you bankrupt and most of the times people that get very involved with gambling gets mixed in with the wrong people.
Explanation:
These are examples of how addictions can contribute to problems in a marriage.

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.

.
Answer:
Stem cells have the ability to divide through mitosis and produce unspecified cells. Stem cells can be developed into a required tissue because of their ability of differentiation.
Explanation:
A stem cell is a cell that is in an undifferentiated state. This means that it has not specialized in a specific type that carries out a specific function of that tissue, which does not imply that stem cells do not have their own function. The concept of stem cell is due to the ability to originate specialized cells from one or more tissues, depending on the degree of potency or plasticity it has. They are found in all multicellular living organisms. Their main characteristic is that by reproducing through the process of mitosis (they divide into two cells) they can form more stem cells or differentiate, that is, they become specialized cells, in such a way that they are essential for the renewal of cells in different tissues. and to repair them.
Stem cells have the ability to divide through mitosis and produce unspecified cells. They can be developed into a required tissue because of their ability of differentiation.
Stem cells are a special type of cell that may develop into a variety of specialized cells inside the body. They have the ability to differentiate into more specialized cells through the process of mitotic activity (mitosis) and perform restorative and regenerative roles.
Stem cells have significant and potential treatment for a variety of diseases due to their capacity to repair, regenerate, and grow into certain specialized cell types.
For example, bone marrow transplantation for people suffering with sickle cell disease.

there are more hydrogen atoms in living organisms than any other atom, but oxygen is more abundant in terms of mass.
why is this statement true?
Answer:
They are compounds made of the same two elements, but each contain different numbers of atoms. ... There are more hydrogen atoms in living organisms than any other atom, but oxygen is more abundant in terms of mass. Why is this statement true? Hydrogen atoms have a lower mass than oxygen atoms.
Answer:
The statement is true because there is more of the actual atom hydrogen in living organisms, as oxygen is more abundant in the world, but not in every living organism.
Explanation:
For example, there is more hydrogen in living organisms added up, but there is more oxygen in the world. If you add them all up, the mass of oxygen would be more then hydrgen, but more hydrogen in actual living organisms.
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.

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.
how does the brightness/luminosity change throughout the cycle of a massive star?
Answer:As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.
Explanation:

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.
Explanation:
Other organisms were another factor. What kinds of changes in other populations of organisms could be affecting the moths?
The presence of the industrial revolution caused moths to evolve, as different colored moths became dominant in certain phases of climatic changes, such as the black moth, which gained advantage during the industrial revolution.
What is the significance of the evolution of moths?In moths, evolution occurred as a result of changes in climatic conditions, such as before the Industrial Revolution, when the environment was clean, giving light-colored moths an advantage over the predator-favored black moth. The environment became darker after the industrial revolution as a result of smoke, which favored dark moths.
Hence, the presence of the industrial revolution caused moths to evolve, as different colored moths became dominant in certain phases of climatic changes, such as the black moth, which gained advantage during the industrial revolution.
