Answer:

mosquito's offspring have resistance to the chemical due to mutation in the GSTe2 gene which is passed down to the offspring, which makes insects break down chemical so it’s no longer toxic. It has also shown that this gene makes insects resistant to pyrethroids raising the concern that GSTe2 gene could protect mosquitoes against the major insecticides used in public health making this mutation beneficial to the mosquitoes.This means that the mosquito can survive by breaking down the poison into non-toxic substances.

Explanation:

A mutation is a change in DNA, the hereditary material of life.

Harmful mutations may cause genetic disorders or can be cancerous, while neutral mutations are changes in DNA sequence that are neither beneficial nor detrimental to the ability of an organism to survive and reproduce.

calledbeneficial mutations. Beneficial mutation in the other hand, lead to new versions of proteins that help organisms adapt to changes in their environment. This is the case of the mosquito offspring and there resistance to chemicals.

Answer:

When a species of mosquito or insect is resistant to any chemical, it is good for the species of the mosquito because it does not kill it, but if it seeks to combat it in crops or in human environments it is dangerous.

Explanation:

Whenever a mosquito or a species is resistant to a chemical, it means that it has an adaptation mechanism so as not to die, as it did before, against that chemical.

What evidence did Galileo provide to support Copernicus's heliocentric model? Check all that apply.
Law Incorporation [45]

Answer:

<em>- Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all things.</em>

<em>-Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.</em>

Explanation:

Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Beginning on January 7, 1610, he mapped nightly the position of the 4 “Medicean stars” (later renamed the Galilean moons). Over time Galileo deduced that the “stars” were in fact moons in orbit around Jupiter.

At about the same time, German mathematician Johannes Kepler was publishing a series of laws that describe the orbits of the planets around the Sun. Still in use today, the mathematical equations provided accurate predictions of the planets’ movement under Copernican theory. In 1687, Isaac Newton put the final nail in the coffin for the Aristotelian, geocentric view of the Universe. Building on Kepler’s laws, Newton explained why the planets moved as they did around the Sun and he gave the force that kept them in check a name: gravity.

Answer:

(c) 16-24 calories

Explanation:

In the  question it is provided that 4 - 6g of  highly concentrated glucose product helps to get on the feet within 20 to 30 minutes.

Also we know that 1 gram of glucose contains 4 calories.

Therefore,

4g of glucose = 4 × 4 calorie

                       = 16 calories

6g of glucose = 6 × 4 calorie

                       = 24 calories

Thus, we can say that the minimum number of calories needed to bounce back after the workout is 16 - 24 calories

Hence, the correct answer is option (c) 16-24 calories
