Ahat [919]3 years ago
6 0

Answer:

a. Exothermic.

Explanation:

We know that there are several types of chemical reactions. In some reactions, the energy which is absorbed to break down the bonds of the reactants becomes less than the energy which is released at the time of forming new bonds of the products.

This means that in the whole reaction, energy is released as either light or light. This type of reaction is called an exothermic reaction.

An organism is heterozygous for a gene that follows Mendels law of dominance which allele will be expressed as its phenotype
stellarik [79]

Answer:

The dominant allele

Explanation:

The dominant allele will be expressed because in a heterozygous genotype, the phenotype will always show the dominant gene (in Mendelian genetics)

This is because the dominant allele will dominate the recessive one and it will "mask" the recessive allele.

Nucleic acids, proteins, and other large biological molecules are known as polymers because
mart [117]

Answer:

Please read the explanation section.

Explanation:

They are called polymers because they contain many small, repeating sub-units bonded together.

In the chemical and biological science, some small molecules make a polymer, which is a molecule. A polymer is that kind of molecule, which is the result of binding up between smaller molecules called monomers.

A monomer is a type of polymer that is resulting from the assembly of many small units that are similar in nature. A monomer has a chemical compound with repetitive structural units. A polymer is a molecule made up of a chain of similar molecules, called

E.g., DNA, glycogen, amino acid, and proteins are polymers

What is one way the gas giants differ from the terrestrial planets
Vesna [10]
<h3><u>Question</u></h3>

what is one way the gas giants differ from the terrestrial planets?

<h3><u>ANSWER</u></h3>

Planets that are largely comprised of rock, such as rocky or terrestrial planets, are not like gas giants. Unlike rocky planets, gas giants lack a clearly defined surface there is no obvious line separating the atmosphere from the surface. The atmospheres of the gas giants are primarily hydrogen and helium.

The total DNA content of each daughter cell is reduced during meiosis because
Tanya [424]

Answer:

E) sister chromatids separate during anaphase of meiosis I.

Explanation:

Chromosomes are composed of two chromatids which are joined together through centromere. Chromosomes get doubled its chromatids during its S phase of Interphase. Although chromosomes number remains the same as after S phase but number of chromatids becomes double.

For Example:

In humans 46 chromosomes are present before S phase and 46 chromosomes after S phase. only difference is that chromatids before S phase is 46 in number while after S phase it becomes double i.e becomes 92.

During Prophase 1 of Meiosis 1 these 46 chromosomes with 92 chromatids get arranged in  manner that homologous chromosome pair comes close together and form 23 pairs.

During Metaphase 1: These 23 pairs get arranged in center and attached with spindle fiber present inside cells. Each spindle fiber attach to one member of the pair in a manner that 23 spindle fibers from one side of pole attached to one member of homologous chromosome pairs and 23 spindle fibers from other side of pole attached to other member of homologous chromosome pairs.

In Anaphase 1 of Meiosis 1 these spindle fibers get contracted and pulled attached chromosome along with them towards opposite poles. In this manner chromosome numbers in Meiosis become half as compared to the Mitosis

So Correct Answer of the question is

E. sister chromatids separate during anaphase of meiosis I.

HURRYYYYYYYY !!!!!!!!!! Heat flows from BLANK substances.
horsena [70]

Explanation:

When a substance is hot then its molecules will have high kinetic energy. As a result, there will be more number of collisions between its particles.

Therefore, the substance will have more energy and this energy is given out in the form of heat.  

Therefore, we can conclude that heat flows from warmer substances.
