Do you think partial melting will occur if there is direct contact of hot molten rock in the Earth’s crust?
Answer:
As it moves toward the surface, and especially when it moves from the mantle into the lower crust, the hot magma interacts with the surrounding rock. This typically leads to partial melting of the surrounding rock because most such magmas are hotter than the melting temperature of crustal rock.
What do you think the similarities are Between baking a cake and rocks
Answer:
When the baking temperature reaches 300 degrees Fahrenheit, sugar undergoes what is known as a Maillard reaction, a chemical reaction between amino acids, proteins and reducing sugars. The result is browning, which forms the crust of many baked goods, such as bread and baking a rock will just heat it up

9. The gap 1, gap 2, and synthesis stages of the cell cycle make up...
a. interphase
b. telophase
c. cytokinesis
d. mitosis
Answer:
a. interphase
Explanation:
The gap 1, gap 2, and synthesis stages of the cell cycle make up the interphase. Thus, the correct option is A.
What is the cell cycle?The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. The cell cycle can be divided into two phases. They are:
The Interphase.The M-phase (division phase).Interphase comprises the G1 phase, S-phase, and G2 phase. The G1 phase is the resting phase. DNA synthesis does not take place. It is involved in the synthesis of RNA and protein. S-phase deals with the synthesis of DNA and histone proteins.
While the G2 phase is the continuous synthesis of RNA and proteins. After this phase, a cell enters the M phase.
Therefore, the gap 1, gap 2, and synthesis stages of the cell cycle make up the interphase. Thus, the correct option is A.

Can a purine pair with a purine?
Answer:
A always pairs with T and C always pairs with G. A and G are purines, meaning that they have two rings, while T and C are pyrimidines, meaning they have one ring. Due to the Watson and Crick model, the width of DNA is constant, meaning that there must be a consistant width in each base pairing. As a result, only a purine can pair with a pyrimidine, giving each base pairing a total of 3 rings.

What is a Nucleotide?Nucleotides are the organic molecules which consist of a nucleoside molecule and a phosphate moiety. Nucleotide molecules serve as monomeric units of the nucleic acid polymers such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all the life-forms which are found on the Earth.
A nucleotide molecule consists of a nitrogen-containing base such as adenine, guanine, thymine, or cytosine in DNA and adenine, guanine, uracil, or cytosine in case of RNA molecule, a phosphate group, and a pentose sugar such as deoxyribose in DNA and ribose in RNA.
Therefore, the correct option is A.

The formula for density is mass + volume O mass - volume O mass x volume O mass : volume
Answer:
mass : volume
Explanation:
Density is a physical quantity. An intensive property which can be used to determine any substance in nature.
Density is a unique quantity because it highlights the mass per unit volume of a substance.
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
Mass is the amount of matter contained in any substance
Volume is the space they occupy
We clearly see that the ratio of mass to volume gives the value of density.

Vernon is studying the population of deer in a tract of forest. He gathers the following data.
Birth rate: ~50 deer/year
Death rate: ~70 deer/year
Which additional observation would support the conclusion that the deer population is NOT changing size from year to year, meaning that the net population change is 0?
Answer: About 20 deer per year immigrate to the tract of forest.
Explanation:If 50 deers are born every year and 70 deers die every year but the population doesn't change it means deers immigrate to the tract of forest.
The deer population is not changing size from year to year, meaning that the net population change is 0 that is about 20 deer per year immigrate to the tract of forest.
What are the different types of population ?Population refers to a discrete groups of individuals with their basic characteristics, It consists of a same group of species present in a particular geographical location and interbreed with each other.
In a population all individuals are not able to survive and reproduce due to presence of genetic variations, some population are Finite or countable.
Infinite Population is uncountable population in which the counting due to the impossible population and Existent Population of the individuals, whose unit is available in solid form.
Hypothetical Population is another type of population and its unit is not available and Most of the populations are unstable due to the presence of various physical factors.

What is parasitic mode of nutrition? Explain with examples.
Answer:
Explanation:
ANSWER 1) Parasitic nutrition is a mode of heterotrophic nutrition where a parasitic organism lives on the body surface or inside the body of another type of organism (a host)
Examples of parasitic mode of nutrition are mosquito, ticks, lice, bedbugs , tapeworm
because lives on the body surface or inside the body of other organism called host.
ANSWER 2 ) Organisms that live in or on other organisms and acquire food at the expense of its host are called parasites. Most parasites are harmful to the hosts’ health; sometimes, they even kill the host. Both animals and plants may serve as a host. Unlike commensalism, the parasite causes some harm to its host. A few examples of parasites are louse on a human head, Cuscuta plant and tapeworms.
Cymothoa exigua is an unusual parasite. It is also known as the tongue-eating louse and is aptly named so as it is found in the mouth of the marine fish Lithognathus. It essentially severs the fish’s tongue, cutting off the blood supply and causing the tongue to fall off. The louse then attaches itself to the remains of the tongue and essentially acts as the fish’s new tongue.

When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?
Energy cell harvesting is impotant. Cells need energy so they can move from one place to another and ATP helps that. ATP is consiered "energy currency" of the cell and it's useful for storing egery and helping molecules/cells move around.
Protein to move against concentration gradient requires energy. Protons go trhough a protein channel called ATP synthase which helps them move out of the mitrochonrial matrix.
The phosphorylation of another molecule can assist a protein to transport molecules against their concentration gradient by energizing them.
PHOSPHORYLATION:
Phosphorylation is the process by which a phosphate group is added to another molecule. Adenosine triphosphate (ATP) loses a phosphate group to another molecule in the process of phosphorylation to energize the molecule. This is the process by which energy is released for use. Moving molecules against a concentration gradient requires energy input in form of ATP, hence, phosphorylation can assist a protein to transport molecules against their concentration gradient by energizing them.Learn more at: https://brainly.com/question/15967997?referrer=searchResults
