Answer:

"Because there is strong evidence to support it"

Explanation:

Theories are generated with lists of tests and comparison, as hypothesis are only generated by observation. In fact, hypothesis are part of the process to generate theory.

Answer:

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle.

The human body does not constantly lose water through _______.
S_A_V [24]

The human body does not constantly lose water through hydration and circulation. When someone is hydrated, he is drinking an enough amount of water to sustain the needs of his body. Circulation then helps this in distributing the water in different parts of the body.

This primate lives in the grassy highlands of Eastern Africa. It has arms and legs that are relatively equal in length and a sho
Serga [27]

Answer:

On the basis of the given information, that is, the ape exhibiting small incisors and biphodant molars, shows that they generally consume fruits and seeds as the prime part of their diet. Thus, mainly the apes feed on fruits, leaves, and seeds, thus it makes them vegetarian.  

However, it has also been observed that canine teeth are found in both males and females, though they are larger in males. This shows that apes can consume meat from small birds and animals occasionally.

Alex is participating in a 50 meter dash. Predict the most important chemical process his muscles will rely on during this race.
natta225 [31]

Answer: The correct answer to the question is option E

BOTH ANAEROBIC RESPIRATION AND CREATININE PHOSPHATE BREAKDOWN.

Explanation: 50 meter dash is a race,a form of exercise, energy is required as well as muscle contraction and chemical processes.

Alex muscles will rely on the following chemical processes during the race;anaerobic respiration and creatine phosphate breakdown.

These chemical processes are explained below;

Aerobic respiration uses oxygen to generate energy but unlike aerobic respiration, anaerobic respiration breaks down glucose to provide energy and create adenosine triphosphate(ATP), lactic acid and ethanol.

Muscle contraction cannot take place without the supply of energy by ATP, molecules can store energy in it's phosphate form, this molecule is known as creatine phosphate,when this happens,ATP that is in excess will then transfer it's energy to creatine,this action will produce creatinine phosphate and adenosine diphosphate (ADP) and they will now be stored as reserve of energy that can be used to produce more ATP and thus energy is produced.

What is the Molecular mechanism of DNA replication?
kolezko [41]

Answer:

DNA replication a process of copying of a cell's DNA.  DNA replication is semiconservative process which means that each strand in the double helix helps in the synthesis of new, complementary strand and conserve the parent template.

The Molecular mechanism of DNA replication is as following:

  1. The double starnded DN in binded with hydrogen bond, the enzyme helicase opens up the DNA at the replication fork.
  2. A single stranded binding protein prevent the rewinding of DNA and so binds to the DNA around the replication fork
  3. Topoisomerase prevent supercoiling at replication fork.
  4. The ezymes primase come in action and produces RNA primers which are complementary to the DNA strand.
  5. DNA polymerase III help to extends the primers and allow them to add  to the 3' end, to make new DNA.
  6. DNA Polymerase then remove RNA primers and replace with DNA.
  7. DNA ligase blocks the the gaps between DNA fragments.

So, this is the molecuar mechanism of DNA replication.
