Answer:
Mitosis & sexual reproduction
Explanation:
Multicellular organisms depend on mitosis for growth and repair. When an animal, plant or other multicellular organism grows, it makes more cells through mitosis. Organisms can repair some of their tissues, using mitosis to regenerate new cells.

Speculate whether Type I or III survivorship is more typical of early or late succession in ecosystems and which population age-structure (rapid growth or zero/negative growth) is more typical of early or late succession.
Answer:
On the basis of the given information:
Type I survivorship curves - high survival rate through most of life, large organism, long life span, slow development, and few protected progeny. Slower growing organisms are present and typically of late succession
Type III survivorship curves - juvenile mortality, but live for a long time, less parental care, smaller animal, early reproduction smaller body structure. In the early succession, this type of survivorship is more common.

The graph shows the effect of pH on the rate of reaction to three different enzymes. What does the graph show?
Answer:
Regarding the effect of pH on the reaction rate of three different enzymes, what the graph shows is that each enzyme works better at different pH (option A).
Explanation:
Enzymes are specialized protein molecules whose function is to contribute to faster reactions with lower activation energy. To fulfill this function, enzymes must be in an optimal range of temperature and pH.
The graph shows three enzymes, one in an acidic medium, one in a neutral medium and one in a basic medium. The reaction rate of each enzyme is similar, indicating that each is working at an optimum pH. The best interpretation that can be drawn from the graph is that each enzyme works best at a different pH.
The other options are not correct because:
B. The variable "temperature" is not included in the graph.
C and D. Since the comparison of the reaction rate of a single enzyme at different pH is not being made, the graph is not useful to indicate whether an enzyme works better in acidic or basic conditions.

8. Hermaphroditic animals—mostly invertebrates such as worms, bryozoans (moss animals), trematodes (flukes), snails, slugs, and barnacles—are usually parasitic, slow-moving, or permanently attached to another animal or plant.
9. A bacteriophage is a type of virus that infects bacteria. In fact, the word "bacteriophage" literally means "bacteria eater," because bacteriophages destroy their host cells. All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure. A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces the cell to produce viral components. Eventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis. Bacteriophages occasionally remove a portion of their host cells' bacterial DNA during the infection process and then transfer this DNA into the genome of new host cells. This process is known as transduction.

OK, crack you knuckles and wipe the spittle from your mouth. Please summarize transcription using the following terms which you will underline as an extra added benefit:
RNA Polymerase
Nucleus
DNA
mRNA
Uracil
…and Yoda.
Answer:
This question is asking to describe the process of transcription. Please find the description below.
Note: the terms will be in BOLD
Explanation:
Transcription is the first stage of gene expression which involves the synthesis of mRNA from a DNA template. Transcription, which occurs in the NUCLEUS where the DNA is located, occurs in three stages namely: initiation, elongation and termination.
- In the initiation stage, an enzyme called RNA POLYMERASE binds to a region on the DNA molecule called PROMOTER. This causes the double strand of the DNA to unwind (separate).
- In the elongation stage, RNA polymerase begins to add nucleotides that are COMPLEMENTARY to those on the strand it reads. This follows the complementary base pairing rule i.e. Adenine-Thymine, Guanine-Cytosine. Note that, URACIL base replaces thymine in the RNA molecule.
- In the termination stage, the RNA polymerase detaches from the strand when it encounters a termination signal, thereby, releasing the single stranded mRNA molecule.

Which structures of the digestive system, aside from the small intestine, release substances that help break down food in the small intestine?
stomach and liver
liver and large intestine
pancreas and liver
large intestine and pancreas
Answer:
Explanation:The pancreas makes enzymes that help digest proteins, fats, and carbs. It also makes a substance that neutralizes stomach acid. These enzymes and bile travel through special pathways (called ducts) into the small intestine, where they help to break down food. The liver also helps process nutrients in the bloodstream

Which of the following best describes osmosis?
Select one:
a.
Osmosis is the active transport of water across a membrane toward an area with a higher concentration of larger molecules.
b.
Osmosis is the spontaneous movement of water across a membrane toward an area with a lower concentration of larger molecules.
c.
Osmosis is the spontaneous movement of water across a membrane toward an area with a higher concentration of larger molecules.
d.
Osmosis is the active transport of water across a membrane toward an area with a lower concentration of larger molecules.
Osmosis is the type of passive diffusion in which, solvent molecules move from, a lower concentration of solute particles to a higher concentration of solute particles through a semipermeable membrane, hence option C is correct.
What is osmosis?It is the kind of passive transport that allows the transport of only solvent particles through the semipermeable membrane, on each side of the membrane concentration of solvent and solute particles having different concentrations.
It is not an active transport and does not require energy, the process is running till the equilibrium is reached at both sides of the membrane. it defines as the spontaneous movement of water.
Therefore, osmosis is the spontaneous movement of water from toward an area with a higher concentration of larger molecules through the membrane.

Describe what happened to the deer and wolf populations between 1971 and 1980. How did the number of wolves affect the number of deer?
Answer:
as the deer pop. increased, the low pop. of starving wolves increased since there are more preys, but the wolves pop. marginally declined as the deer pop. went down.
The changes in the deer and wolf populations between 1971 and 1980 were that the deer population decreased due to an increase in the number of wolves.
What is population?The term population is commonly used to refer to the number of individuals in a given area.
It should be noted that wolves are deer predators, so the wolves kill and eat the deers. In this case, as the wolf population grows, they will hunt and kill deer. This will result in a decrease in the deer population.
In this case, an increase in the wolf population will result in a decrease in the deer population.
On the other hand, assuming the wolf population was reduced, this would have resulted in an increase in the deer population.
Thus, this can be concluded regarding the given scenario.
