Genetic variation increases in a population of predators after natural

Genetic variation exists in a population leading to individuals with
adaptations with different survival frequencies.
D)
E)
Indiana is home to fossilized
The correct answers are:
-Genetic variation decreases in a population of prey after natural selection acts on it.
-Genetic variation exists in a population leading to individuals with adaptations with different survival frequencies.
Genetic variation creates new variants of a gene; such a variant is called an allele. These variations occur as a result of the interaction between individuals with their environment, where it affects them in a way that determines their survival or not, as a consequence of their adaptability to the surrounding context. Thus, natural selection occurs, which establishes which individuals survive and which individuals do not. Thus, individuals characterized as prey who develop defense elements against hunters will be the ones who survive, while those who do not will be the ones who will perish.

Which step in cellular respiration produces the most ATP?(1 point)
Krebs cycle
glycolysis
electron transport chain
lactic acid fermentation
Answer:
it's Kerbs cycle which produces most ATP in cellular respiration
Answer:
The answer is electron transport chain
Explanation:
The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria.
The formation of ATP occurs by oxidative phosphorylation. Theoretically, 34 ATPs are produced in the ETS by the complete oxidation of a glucose molecule. Electrons are transferred from NADH or FADH2 to O2 by a series of carriers and are coupled to ATP synthase for the formation of ATP.

Pump jacks use upward force and pressure to slowly move oil up a drill shaft. Which statement best describes an environmental consequence of this process?
O Soil is removed by the force and pressure of the drilling process.
High salinity of wastewater reduces soil fertility and growth of vegetation.
Wastewater is contaminated with oil and becomes sludge in landfills.
O Heavy metals are released into surrounding soil, poisoning local vegetation.
The main consequence of this process is that the soil is removed by the force and pressure of the drilling.
For the extraction of oil from the land, the vegetation is removed that destroys the habitat of many organisms as well as the degradation of soil occurs due to the force and pressure of the drilling machines.
In water, the aquatic organisms including plants and animals are adversely affected due to this process of extraction so we can learn that there are many consequences of extracting oil from the soil to the surrounding environment..

On a graph, the vertical axis is
the y-axis and the horizontal
axis is the x-axis. Onəwhat axis
should the INDEPENDENT
VARIABLE be placed?
A
on the vertical or y-axis
B
on the horizontal or x-axis
Answer:
x-axis
Explanation:
you control those values/variables
On a cartesian plane, the independent variable belongs on the x-axis.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
The independent variable is the variable that is being manipulated or controlled in an experiment, and its values are typically plotted along the horizontal or x-axis.
The dependent variable, which is the variable being measured or observed in response to changes in the independent variable, is usually plotted on the vertical or y-axis.
This convention allows us to easily visualize and analyze the relationship between the two variables.
therefore, The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).

A barrier enclosing the cell, the cell wall is located outside the plasma membrane. The plasma membrane can be up to 100 times thinner than a cell wall, hence option D is correct.
What is a cell wall?Cellulose, a polysaccharide sugar that gives the cell wall strength, makes up the majority of its composition.
The leaf blades of L. perenne and T. repens and the stems of Z had the thinnest cell walls (0–9 m) and the thickest (2–0–3 m) among the cells classified as thick-walled.
Compared to gram-negative cells, gram-positive cells have substantially thicker cell walls. The typical thickness of the gram-positive cell wall is 20–80 nm, whereas the typical thickness of the gram-negative cell wall is 5–10 nm.
Therefore, the cell wall is up to 100 times thicker compared to a cell
membrane, hence option D is correct.

reaction to the cut.
Answer:
A.
Explanation:
These systems will be involved!
Hope this helps, have a great day.
The nervous system, circulatory system, and integumentary system are body systems involved immediately when you cut a finger.
The integumentary system is the system that groups the natural covering of an organism, for example:
SkinBarkShellThe nervous system is in charge of electrical signals. These signals are those produced by the senses such as taste, smell, sight. Also, they are responsible for sending signals of pain, satisfaction, pleasure, and others to the brain.
The circulatory system is the system in which blood is transported throughout the body for oxygenating and energizing the entire body.
When someone cuts themselves they feel pain (nervous system), blood comes out (circulatory system) and their skin opens and some of its lower layers (integumentary system) can be seen. Therefore, the correct answer is A.
