Which pairings match protozoa with the structures they use to move? amoeba: flagellum; euglena: cilia; paramecium: pseudopod amoeba: pseudopod; euglena: flagellum; paramecium: cilia amoeba: flagellum; euglena: pseudopod; paramecium: cilia amoeba: pseudopod; euglena: cilia; paramecium: flagellum

Answers

Answer 1
Answer:

Answer:

The correct answer is -  amoeba: pseudopod; euglena: flagellum; paramecium: cilia

Explanation:

Protists use different type of structures for their movement known as pseudopods, flagella, and cillia.

Pseudopods are the structures found in amoeba in which flowing of protoplasm moves the amoeba forward.

A euglena moves by strikes or whip its flagellum, that is a long appendages, like propeller of a helicopter.

Cilia are thin, very small tail-like structure that stretched outward from the of body of paramecium.

Thus, the correct answer is -  amoeba: pseudopod; euglena: flagellum; paramecium: cilia

What factor determines when a species is considered invasive?a. It has positive environmental impacts.
b. It is environmentally damaging.
c. It spreads outside its native range.
d. It spreads within its natural range.

Answers

Answer: b. It is environmentally damaging.

An invasive species is a kind of living organism such as amphibian, insect, bacteria, fungus, plant or even the seeds or eggs of the organism that is not native to a region or ecosystem but introduced either accidentally or by the migration of the species in search of food, shelter, habitat and mates. The invasive species has the potential to compete with the native species, can harm the environment, and health of the human or other living species.

The invasive species spread rapidly after starving the population of native species for food, shelter and for other needs. The invasive species can affect the availability of water and can damage the quality of soil nutrients. Once it is introduced into a habitat it changes the environmental condition of that habitat adversely.

Why is it that two species cannot occupy the same niche for an extended period of time?

Answers

A niche is a specie's function in its habitat or its level on the food chain, so two species competing at the same level for the same food and habitat eventually one species will have to migrate or starve due to lack of food.

Answer:

In terms of ecology a niche can be defined as role or function an organisms play within the ecosystem. A niche represent the interaction of an organism with the living and non living components of the ecosystem. It is represented by predator-prey relationships, parasitic and mutualistic properties and other functions. The two species cannot occupy the same niche for an extended period of time, this can be explained by competitive exclusion principle. According to this principle, no two species can have the same ecological niche. The two or more species competing for the same resource in an ecosystem the one species having more favorable adaptations will be able to thrive resources better than others. Therefore, this  will result in the decrease in abundance, migration and extinction of weak and less competitive species.


Which of the following is an unsegmented animal with a free-swimming larval stage? A. flatworm. B. annelid. C. mollusk. D. echinoderm

Answers

The answer is C. mollusk.

Among the all choices, echinoderm and annelid are segmented animals. So, it leaves flatworm and mollusk as possible answer. However, flatworms have no a free-swimming larval stage. Mollusk is an 
unsegmented animal with a free-swimming larval stage we were looking for. After eggs production, from them trochophore larvae can emerge. This trochophore larvae is planctonic which means it is a free-swimming.

Of glucose produces glycogen, the storage form of sugar, found in the liver and muscles

Answers

Glycogen is a homopolysaccharide formed by units of glucose and is sometimes referred  to as animal starch. It can reach up to a molecular weight of 10 to the power 8  DA which corresponds to about 600,000 glucose molecules.

 The function of glycogen is that it is the principal form in which glucose is stored in animals and is present in the liver, muscle (skeletal and heart muscle) and in lower amounts in nearly all the other tissues and organs.

Glycogen makes up about 10% of liver weight and 1% of muscle weight. Although it is present in higher a concentration in the liver, the total amount stored in muscles is much higher due the greater mass of the muscles as compared to the liver. 

 

the answer to the question is polymerization

Drinking too much water during exercise can cause a condition in which the concentration of sodium in the blood is lower than normal. What response do you expect to happen as the body tries to restore homeostasis?

Answers

Extensive drinking of water during exercise leads to a condition called as hyponatremia. In this, water causes dilution of the blood and sodium levels drops too low. To maintain homeostasis in such situation, water intake shoud be reduced, sodium containing fluids should be taken, extra salt may also be added to the food, to maintain normal sodium levels in the blood.

Answer: Cells shrivel as water moves out of them.
