Answers

Answer 1
Answer:

Answer:

The main organs of the excretory system are the kidneys and skin

Explanation:

The excretory apparatus is composed of different organs to perform the vital function of excretion. Without the excretory apparatus it would be impossible to live.

Excretion consists in removing waste substances from the body. These substances are the residues or remains of the functioning of the cells. The substances that are excreted are liquid or gaseous. Liquids such as urine or sweat. Sodas such as carbonic anhydride.

The digestive system eliminates the solid remains that occur in the digestion of food, but are not generated by the body s cells because they never passed into the blood.

The skin is an organ of great importance since it covers and protects everything that your body has inside. Without the skin, muscles, bones and organs would not be in their proper place. It is also responsible for protecting the body because it helps maintain an adequate temperature and allows the sense of touch to be had. The skin is the body s largest toxin excretory organ.

The kidneys are a couple of organs whose main function of the excretory system is to work and excrete urine. The kidney acts as a filter on the body. On the one hand, it fulfills a regulatory function, maintaining optimal levels of water, glucose and salts in the blood. And, on the other hand, it performs a purifying function; it is responsible for extracting from the blood the toxins accumulated in it, such as urea or uric acid.

Answer 2
Answer:

Kidneys and skin are part of the excretory system the bladder is part of the urinary system.

What does genetics mean?

The scientific study that genes and heredity, or how particular characteristics or traits were passed through parents to their children as a consequence of alterations in DNA sequence, is known as genetics. A gene is a section of DNA that includes instructions for creating one or even more molecules that support bodily function.

What are some genetic examples?

The study of genetics is known as genetics. Our genes store information that is copied from one generation into the next. For instance, genes are the reason why one kid has blonde highlights like their mother and their sibling gets brown hair unlike their father.

Natural selection produces changes most quickly in 1 species with short reproductive cycles
2 individual pathogens killed by antibiotics
3 complex multicellular organisms
4 individuals that produce a small number of offspring

Answers

I have reason to believe that 2 is the answer, because since all individual pathogens are the same, they will all react in the same way to the antibiotic. thus natural selection will exterminate them the fastest.

Global warming threatens the survival of Arctic foxes. Which of the following factors could be involved? I. Competition with other fox species spreading north
II. Reduction in numbers of prey species of Arctic foxes
III. Decrease in oxygen availability to Arctic foxes
I only I only
B. I and II only
C. II and III only
D. I, II and III

Answers

The correct answer is B.

Global warming encourages other fox species to spread into areas previously unsuited to them.  This increase in fox populations, and also change in environment, will reduce the amount of prey available in the area.

Oxygen availability will not be impacted enough to cause the arctic foxes to suffocate.  If it did, humans would be at risk too!

Based on your knowledge of signal amplification, which type of chemical messenger can have relatively small concentrations within the bloodstream and still get a large compensatory response

Answers

The correct answer is lipophobic signal messenger.

Lipophobic signal molecules cannot enter cells by simple diffusion through the cell membrane and because of that, these signal molecules bind to receptor proteins on the cell membrane. The response time for pathways linked to membrane receptor proteins is very rapid-within milliseconds to minutes.
