Answer:
A
Explanation:
In ecology, we define producers as organisms that are able to make their own food through photosynthesis or chemosynthesis. ... An organism that cannot make its own food cannot be a producer in ecology by definition.
Explain why enzymes are essential or important to maintaining
homeostasis in living things.
Answer:
Enzymes are proteins that catalyse (speed up) vital chemical reactions inside the body. Enzymes will only function properly under a small range of certain conditions, such as preferred pH and temperature. If any conditions are outside their specific range then the enzymes cannot function. This could cause the organism to die. Homeostasis relies on automatic control systems that include nervous responses (nervous system) or chemical responses (endocrine system). Receptors and effectors are also needed

What is the relationship between the biodiversity of an ecosystem and its
ability to rebound from disturbance?
A. A biodiverse ecosystem is not affected in any way by disturbance.
B. A biodiverse ecosystem harbors many interactions, thus a
disturbance may impair some interactions, but not all.
C. The relationship between the biodiversity of an ecosystem and its
ability to rebound from disturbance is unknown.
D. A biodiverse ecosystem has so many interactions that the
slightest disturbance will destroy it.
Answer:
B. A biodiverse ecosystem harbors many interactions, thus a disturbance may impair some interactions, but not all.
Explanation:
Biodiversity is the variation of life forms in an environment. This is as a result of available nutrient and energy to support the various life forms.
The relationship between biodiversity and rebound from disturbance is such that a biodiverse ecosystem is able to resist any change. The disturbance might affect proportion of the populace. But on the long organisms can survived and be propagated again.Answer:

Answer: in 1925, people were sick and planes couldn’t land in nome, Alaska. Teams of dogs delivered the medicine
Explanation: I got it right on a quiz
In 1925, people were sick and planes couldn’t land in Nome, Alaska. Teams of dogs delivered the medicine has the most objective tone. Thus, the correct option is D.
What is the objective tone?Objective tone is an impartial tone. This tone does not show any kind of feelings for or against a topic which therefore, is an unbiased or neutral feeling. The objective tone often uses higher level words and avoids pronouns such as I and you in the sentences, creating a type of formal tone. Subjective tone is a personal, biased, emotional, and often informal kind of tone.
Objective tone refers to an impersonal style of writing, which gives us the information about something however it does not include any information about the writer. So, a sentence like this: "In 1925, people were sick and planes couldn't land in Nome, Alaska. Teams of dogs delivered the medicine" is of the objective tone, Because it just tells us a fact.
Therefore, the correct option is D.

How are the functions of a cell similar to the functions of an organ system?
Answer:
Organelles in a cell are essentially the same as organs in an organism. The mitochondria is the powerhouse of the cell, as we all know. It creates ATP, which is what gives the cell energy. This is similar to how we consume food and create energy from it. Cell membranes are similar to skin, as they keep needed things in, and unwanted things out. Our cells need water too, as it helps create the cytoplasm. We need water to keep us alive and well, as it helps to create many of our needed bodily fluids, and rid us of toxins.
If the pituitary is so important and Eric is not getting replacements of hormones the pituitary makes (except for ADH), why isn’t he dead? To answer this question, think through the cascade of events from hypothalamus to effect.
Answer:
The absence of ADH is not too dangerous.
Explanation:
If there is no place for the storage of ADH hormone in the pituitary hormones, no death occur of the individual because ADH is related to the conserve of fluid in the blood. If this hormone fails to perform its function properly, it causes the body to retain too much water. This more water retention may cause you to feel heavier than normal, and less active so the person did not die due to the deficiency of this disease.

A sports medicine major wants to conduct a experiment to determine if there there's a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:
Every day for a week, he counts how many times each player can leg press 350 pounds. The following week, he has each player sprint 40 yards every day. The table shows the average number of leg-press repetitions and the average 40-yard dash time (in seconds) for seven randomly selected players. What is the equation of the line best fit? How many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions? Round any values to the nearest tenth, if necessary.
leg press (reps) 12 | 32 | 7 | 11 | 23 | 28 | 15 |
40-yard dash (s) 8.6 | 14.6 | 7.1 | 8.3 | 11.9 | 13.4 | 9.5 |
Answer:
The correct answer is the equation of the line of best fit is y=0.11x+4.54, and it would take the player 6.96 seconds to run.
Explanation:
Using technology, we calculate the line of best fit; we first enter the data points as a scatter plot, then run the regression tool, which gives us y=ax+b, where a=0.11 and b=4.54.
We now use this equation, y=0.11x+4.54, to calculate the amount of time it would take a player to run 40 yards if the player can do 22 leg-press reps:
y=0.11(22)+4.54=6.96.
Messenger RNA (mRNA) contains the instructions for —
A. building mitochondria
B. protein assembly
C. DNA replication
D. RNA synthesis
Each group of three mRNA bases specifies a particular
A.nucleic acid.
B. protein.
C.amino acid.
D.gene.
Answer: C its Amino Acid
Explanation:
Answer:
Amino acids
Explanation:
Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein. Figure 2: The amino acids specified by each mRNA codon.
b) Identify a dependent variable in the experiments. Identify the reasoning of the scientists when they tested the number of colonies produced by strains C3-PBB and C6-PBB . The scientists also analyzed the number of colonies produced from each of the environmental and clinical isolate strains when the strains were plated on a growth medium lacking the toxic chemical. Justify this analysis.
A dependent variable is the number of colonies produced. The experiment gives a useful insight into the toxicity of the chemicals.
A scientific experiment must always have a dependent and an independent variable. A dependent variable is the variable whose outcome is being determined by manipulating the independent variable which in this case is the presence or absence of the chemicals.
Toxicity of chemical substances is a very important information to scientists as such this experiment is very important because it highlights the toxicity of the chemicals to living things.
