How I would say an object would be called a planet is if #1, if it orbits a star, #2 if it has gravity of any kind, and #3 ( This one doesn't apply to all ) but if it has an atmosphere ( Like Venus or Jupiter )

I haven't got to astronomy yet but from what I know so far is stated. Hope this helped! :D

Answer:

For an object to be considered as a planet, it must satisfy minimum three conditions:

1. The object must be round in shape.

2. The object must orbit the sun in a clear orbit.

3. The object must be biggest in its neighborhood that is it should clear its neighborhood.

For example, Pluto was once considered as planet but it was demoted to a dwarf planet when more similar objects were discovered in its neighborhood.

Some organisms undergo asexual reproduction through mitosis, while others reproduce sexually, and their cells undergo meiosis to

Sav [38]

The answer is A. Meiosis: It increases genetic variation, which helps ensure the species will survive.

Meiosis increases genetic variation. This means there is a great variety of genotypes among the population. Hence, there are organisms able to survive in a wider range of temperature. If there were drastic changes in temperature in an ecosystem, some of the organisms will survive because their genotype allows them to live in such conditions. If there were no variety thanks to meiosis, all of the organisms would die. And that is not beneficial to a species.
Imagine on the other hand that mitosis occurred. Mitosis does not provide a variety of genotypes and all of the organism will be the same. If there were drastic changes in temperature in an ecosystem, all of the organisms would die because all of them could respond to the change in the same way.

Congo red is called a “pH indicator”. What does this mean?

Ivahew [28]

Answer:

A pH indicator is able to tell what level of pH the substance is at. It can tell how acidic a substance is. If a substance has more hydrogen ions than hydroxide ions then it is acidic. If it has more hydroxide ions that hydrogen ions it is an akaline. the acidic scale is from 0 to 14. lower numbers means more acidic and higher numbers means it is an alkaline.

Explanation:

pH stands for potential Hydrogen.

What would be the complementary strand of mRNA

EastWind [94]

Answer:

the complementary nucleotide to adenine.

Explanation:

mRNA is formed as a complementary strand to one of the two strands of the DNA. Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as
