Answer:
Kinetic Energy
Explanation:
Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
Answer:
b. making an observation and asking a question
Explanation:
In scientific method there need to be a situation to be study. In this description, the scientist first observed that in a certain region there is some kind of trees and the other variable is the great amount of deer.
After making different observations, and some research of other areas similar to the one that is study, she is asking what is the relation among the animals and the trees.
The next step will be to formulate a hypothesis using all the data and the two variables that she observed.
The correct answer is that "the T cell enters a state of anergy".
The activation of T cells requires two signals: (1) antigen specific signal presented by an antigen presenting cell (either a macrophage or a dendritic cell) that activates t cell receptors and (2) co-stimulatory signals that is not antigen specific but rather found in the plasma membrane of the antigen presenting cell (i.e. CD28). In the absence of a co-stimulatory signal, the t cell will enter a state of anergy or the inability to produce an immune response toward an offending antigen.
Correct answer: A). Move away from one another
The divergent boundaries are formed when the tectonic plate move away from each other. It forms volcanic islands that occur when the plates move away in order to produce gaps that are filled by molten lava.
The divergent boundary contributes to the formation of seafloor spreading. When the plates that are made up of oceanic crust move away from each other, a crack in the ocean floor appears. Then the magma oozes out from the mantle to fill that crack that results in ocean ridges.
Hence, the correct answer would be option A.
<h2>DNA Mutations</h2>
Explanation:
<em> (A) A base-pair deletion</em>
- <em>Insertion or deletion brings about a frame shift that changes the perusing of consequent codons</em> and, hence, adjusts the whole amino acid arrangement that follows the transformation, additions and cancellations are normally more harmful than a substitution in which just <em>a solitary amino corrosive is modified </em>
- DNA changes brought about by mutagens may hurt cells and cause certain illnesses,<em> for example, malignancy</em>
- <em>Instances of mutagens incorporate radioactive substances, x-beams, bright radiation, and certain synthetic compounds</em>
