Discuss 3 different types of mutations that can happen
Answer:
Explanation:
Un cambio en la secuencia de bases en el ADN o ARN se conoce como mutación . ¿La palabra mutación te hace pensar en ciencia ficción y monstruos con ojos de insecto? Piensa de nuevo. Todos tienen mutaciones. De hecho, la mayoría de las personas tienen decenas o hasta cientos de mutaciones en su ADN. Las mutaciones son esenciales para que ocurra la evolución. Son la fuente principal de todo el material genético nuevo -nuevos alelos - en una especie. Aunque la mayoría de las mutaciones no tienen efectos en los organismos en que ocurren, algunas mutaciones son beneficiosas. Incluso las mutaciones dañinas rara vez causan cambios drásticos en los organismos.

A.bacteria,archaea,eukaryotic
B.bacteria,archaea,animalia
C.archaea,plantista,animalia
D. Life,animals,plants
Answer:
A. bacteria, archaea, and eukaryotic.
Explanation:
Bacteria, archaea, and eukaryotic are the three domains of life.
The three domains system was globally implied. The three domains were Archae, Bacteria and Eukarya. The correct answer is option A.
The three domains of Carl Woese's categorization system are archaea, bacteria, and eukaryotes. The six kingdoms are archaebacteria (ancient bacteria), eubacteria (actual bacteria), protozoa, fungi, plants, and animals.
This classification system divides life into several groups based on differences in the 16S ribosomal RNA (rRNA) structure, the lipid composition of the cell membrane, and antibiotic sensitivity. The main distinction from earlier classification schemes is the division of Kingdom Monera into Archaea and Bacteria.
Therefore, the names of three domains given by Carl Woese were Archae, Bacteria and Eukarya i.e. option A.

Some kidney diseases cause a change in the permeability of glomerular capillaries making them more permeable to plasma proteins. This changes the colloid osmotic pressure, thus drawing water out of the blood and into tissues. The result is
Answer:
The correct answer is edema.
Explanation:
When the capillaries or the tiny blood vessels within the body leak fluid, the condition known as edema takes place. This fluid accumulates in the tissues surrounding it, resulting in inflammation. Edema generally takes place due to mild conditions like consuming more salt, staying or sitting in one position for a long duration, and others.
However, in some situations, edema can also be a sign of an extreme medical condition like kidney disease. During kidney disease, the sodium and additional fluid within the circulation may result in edema. The edema related to kidney disease generally takes place around the eyes and in the legs.
Explain Newton’s First Law and give an example of it
Answer:
When a person jumps out of a moving vehicle, he falls forward due to inertia of motion. One example of Newton's first law in real life is, when you are walking with a glass filled with water, you will notice that the water spills at certain locations when you walk at faster pace. The water inside the glass will remain at rest until you move.
Explanation:
Answer:Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
An object at rest stays at rest.

What makes a species successful in an ecosystem?
Answer:
Beside the intensive loss of forest cover [2], fragmentation of the pristine remnants further affects species [3] and limits their ability to move into adequate areas. Thus the ability to cope with altered landscapes is crucial for the persistence of a species, especially in the face of climate change.

in VDJ recombination occurs in the Group of answer choices variable region of the heavy chain. constant region of the light chain. variable region of the light chain. Both the light and heavy chain.
Answer:
constant region of the light chain.
Explanation:
The VDJ recombination is defined as the process where the T cells as well as the B cells are randomly assembled from the different gene segments. These are mainly known as the variables (V), the diversity (D) and the gene (G). This is done in order to generate the unique receptors which is also called as the antigen receptors so that they can collectively recognize the different types of the molecules. It mainly occurs in the constant region of the light chain.

12. Which has NOT been linked to acid precipitation?
a. Toxic metal poisoning
b. Lower blood pH
c. Respiratory problems
d. Damaged monuments
Answer:
D
Explanation:
Lower blood pH has not been linked to acid precipitation. So, the correct option is (B).
What is Acid Precipitation?Acid rain is defined as rain or any other form of precipitation that is abnormally acidic, meaning that it contains high levels of hydrogen ions. Most water which include drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and averages between 4–5.
Acid rain can be caused by natural causes, such as volcanic eruptions, while acid rain can also caused by human activities such as the burning of fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles, all of which release sulfur and nitrogen oxides into the atmosphere.
Thus, lower blood pH has not been linked to acid precipitation. So, the correct option is (B).

Explanation:
Answer:
Explanation:
Los cloroplastos son los orgánulos celulares que en los organismos eucariotas fotosintetizadores se van ocupando de la fotosíntesis. Están limitados por una envoltura formada por las dos membranas concéntricas y contienen muchas vesículas, los tilacoides, donde se encuentran organizados los pigmentos y demás moléculas que convierten la energía lumínica en energía química, como la clorofila.
El término cloroplastos sirve alternativamente para designar a cualquier plasto dedicado a la fotosíntesis, o específicamente a los plastos verdes propios de las algas verdes y las plantas. Aunque el reciente descubrimiento adiciona a más individuos en la lista, como lo es en el caso de Elysia chlorotica, que al digerir al alga Vaucheria litorea, adquiere los cloroplastos a sus tejidos, y gracias a esto, puede realizar la fotosíntesis.
