What will happen to leave when it lose water?

Answers

Answer 1
Answer: I think you are referring to leaves of plants? If so, the leaf will wither in case it loses water and it will not get to nourish and retain hydration in its leaf body. Also, the water is a very vital element when it comes to producing food for the plant itself.

Answers

People who believe man developed from a lower form of life are called evolutionists. The correct option among all the options that are given in the question is the first option. Evolutionism is a belief that has commonly emerged during the 19th century. I hope the answer comes to your help.

Answer:

Evolutionists.

Explanation:

Charles Darwin is known as the father of evolution. Evolution may be defined as the change in the organisms over generation with time. The natural selection acts as he main driving force in evolution.

The scientists that work to explain the evolution are known as evolutionists. They work on the evolution of life on earth and how the man has evolved first in the life. Evolutionists are the one who believe that  man developed from a lower form of life.

Thus, the correct answer is option (1).

When adult amphibian skin harbors populations of the bacterium, Janthinobacterium lividum (Jl), chytrid infection seems to be inhibited. Which of the following represents the best experimental design to test whether this inhibition is real?A) Inoculate uninfected amphibians with Jl, and determine whether the amphibians continue to remain uninfected by chytrids.
B) Inoculate infected amphibians with Jl, and determine whether the amphibians recover from infection by chytrids.
C) Take infected amphibians and assign them to two populations. Leave one population alone; inoculate the other with Jl. Measure the rate at which infection proceeds in both populations.
D) Take infected amphibians and assign them to two populations. Inoculate one population with a high dose of Jl; inoculate the other with a low dose of Jl. Measure the survival frequency in both populations.

Answers

Answer:

C: Take infected amphibians and assign them to two populations. Leave one population alone; inoculate the other with Jl. Measure the rate at which infection proceeds in both populations.

Explanation:

In scientific investigations, the best way to determine the effect of certain experimental factor on the population of study is to have a baseline for comparison. This is usually referred to as controlled experiment.

In the case of the observation that chytrid infection in amphibians seems to be inhibited by Janthinobacterium lividum, the best way experimental design is to get a population of amphibians suffering from the disease, divide them into two groups and subject them to the same conditions except the introduction of Janthinobacterium lividum to the skin of one of the groups.

A suitable method can thereafter be employed to measure the rate at which infection proceeds in both population. If indeed, the bacterium has the capacity to inhibit the infection, the rate of infection in the group with the bacterium will be significantly less than that of the group without the bacterium.

The correct option is C.
