Answer:

B. the nervous system

Explanation:

The nervous system is one of the body systems that has to do with the passing signal information to and fro the BRAIN and other sensory organs e.g eyes, nose, ears etc. The nervous system is what causes an individual organism to sense and respond to environmental stimuli by passing chemical signals to the brain and back to the site of effect.

According to this question, a frog is able to leap away from a snake because danger is sensed and responded to by the NERVOUS SYSTEM. Information in form of chemical signals (impulses) are passed across the brain of the animal of a possible threat, which then sends back information for the frog to react to such danger by leaping away.

2. If you break down each of the following, how many different atoms would you be able to recover? a) water​
zlopas [31]

Hydrogen and oxygen atoms are produced when we break water molecule because it is made from these two atoms.

<h3>What we gain by breaking water molecules?</h3>

When we break down water molecules, it splits into oxygen and hydrogen molecules. This can only be done throught the process of electrolysis. By passing an electric current, water can be converted into two atoms i.e. hydrogen and oxygen.

So we can conclude that hydrogen and oxygen atoms are produced when we break water molecule.

Functions of the kidney include: 1. removing waste products from the blood. 2. maintaining fluid and electrolyte balance. 3. sec
Pavlova-9 [17]

Answer: 1,2,3

Explanation:

1. One of the major function of the kidney is to excrete metabolic waste. When the blood is perfused through the Bowman's capsule, an ultrafiltrate of the blood is produced in the glomerulus, the filtrate in Bowman's capsule contains salt, glucose, amino acids, nitrogenous waste, etc while the cells and proteins are retained in the blood. The waste are excreted as urine or uric acid.

2. One of the function of the renal tubule is to maintain fluid and electrolytes balance. When the glomerulus filtrate is formed, it contains almost all the crystalloids of plasma which includes water, Na+, Cl-, glucose, amino acid and K+. The renal tubule reabsorb water and solute to the blood to maintain water and electrolytes balance.

3. The kidney secrete a hormone Renin, which control other hormones angiotensin and aldosterone that helps to control blood pressure.

The Hershey and Chase experiments involved the preparation of two different types of radioactively labeled phage. Which of the f
Tems11 [23]

Answer:

The correct answer is B.It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment

Explanation:

Hershey and chase in his experiment lebelled the T₂ bacteriophage with radioactive sulfur and radioactive phosphorus separately. Then they infect E.coli with T₂phage and separated phage from bacteria by centrifugation.

Because DNA contains phosphorus not protein, cells infected with phage containing radioactive phosphorous showed radioactivity bacause DNA enters the cell not protein confirming DNA is the genetic material and radioactive sulfur was found in supernatant.

Compared with pure cultures grown in the lab, microbes in nature usually experience a wider range of environmental conditions, m
Lorico [155]

Answer:

The correct answer is B-typically grow slower than in pure culture

Explanation:

In nature, microbes experience lots of challenges like challenges to get space, to live, to get food, to adapt to the changing environment, to get protection from their pathogens and predators, etc. So these all challenges affects the growth rate of microbes.

In pure culture only one type of bacteria is grown on a nutrient-rich media and a steady environment is given to them to grow. In pure culture, there are no predators and competitors for microbes.  

So all this provide favorable condition for a microbe to flourish in a pure culture so the growth of an organism in pure culture is higher than in nature. So the correct answer is B.
