Explanation:
Wolves that live in snowy climates often prey on rabbits. Some rabbits can move quickly across deep snow because they have large feet that don’t sink into the snow. Rabbits without this adaptation move more slowly across the snow. Which statement best justifies how the rabbit population changes over time?
A. Sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.
B. The ocean water would change its current so that the acidic water is relocated to another area and allow sea coral to survive.
C. The ocean water would change its composition to reduce the amount of carbon dioxide contained and allow sea coral to survive.
D. Sea coral would become extinct because of its inability to make adaptations fast enough to adjust to the changes in the environment
Answer:
It's A
Explanation:
Just like the corals have genetic mutations to adapt to their environment so do the rabbits change their genetic characteristics to make sure the species continue it's lineage by evolving and growing their feet so they can be faster and not sink in the snow, becoming harder preys to catch, otherwise, if their paws were smaller, they would be slower and, therefor, an easy catch for the wolves, probably becoming extinct after awhile.
The statement that justifies how the rabbit population changes over time is sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment. So, the correct option is A.
What is Adaptation?Adaptation is the process by which a species becomes fitted to its environment; it is the result of natural selection's acting upon heritable changes.
Rabbits have to change their genetic characteristics same as the coral have genetic mutations to adapt to their environment and to make sure the species continue its downstream by evolving and growing their feet, so they can run faster in the snow and successfully escape from predators. If rabbits are not evolved with an environment that does not favor them, they are surely eliminated from nature.
Therefore, the statement that justifies how the rabbit population changes over time are sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.

O A. Snow melts on the surface of Earth, causing rivers to form.
B. Magma rises from the surface of Earth, causing lava beds to form.
O C. Wind blows across the surface of Earth, causing sand dunes to form.
O D. Pressure builds under the surface of Earth, causing mountains to form.
Answer/ Explanation:
B. Magma rises from the surface of Earth, causing lava beds to form.
From below or decreasing downward force weigh from above. During uplift, land, as well as the sea floor, rises. All this movement can cause rocks that were once underground to be brought up to the Earth's surface. This process is called uplift.

5. A student is studying how sound travels
through a solid medium by timing
the movement of sound through a
boulder when the boulder is at different
temperatures. Using the information above,
how fast will sound move through the
boulder when it reaches 20°C?
Answer:
570 m/s
Explanation:
The speed of sound is a measure of how fast sound travels through a medium. The speed of sound through various media varies. Sound travels fastest through solids and slowest through gases for example air.
The temperature of a medium affects the speed of sound through that medium. The higher the temperature, the faster sound travels through the medium. This is because, as the temperature of the medium increases, the particles of the medium vibrates faster and faster, thus sound waves are able to be propagated faster through that medium.
From the information provided in the attachment, the speed of sound through the boulder increase by 2 m/s for every 5°C rise in temperature. Therefore, the speed of sound through the boulder when it reaches 20°C will be 570 m/s

Answer:
A. soreness indicates the muscles are growing
D. micro tears signal the muscles to grow
Explanation:
Muscle soreness is one of the indication of muscles are growing as while doing exercise, some inflammation takes place to get bigger and stronger muscles. Some pain signals are sent by the body to make it feel soreness after intense exercise.
Micro tears signal also indicates muscles growth as after intense workout, a certain amount of soreness is felt by our body and these micro tear signals to repair and replenish the muscle tissue that eventually accumulate to form muscle mass.

What would you look for under a microscope on a slide with meiotic cells if you wanted to identify metaphase I
Answer:
This question lacks options, options are: A) A visible nuclear envelope B) Separated sister chromatids at each pole of the cell C) Tetrads lined up at the center of the cell D) A synaptonemal complex E) A cleavage furrow. The correct answer is C.
Explanation:
During Metaphase I, the chromosomes line up at the midpoint or equator between the poles of the cell and are found at their thickest and shortest structure, that is, the tetrads line up at the equator of the cell. They are identified as two double longitudinal sister chromatids. In animals and plants, the chromatids are connected (at their centromeres) to the fusiform apparatus, which has formed between the two centrioles located at the poles of the cell. In many plants, the centrioles are absent. However, the spindle is still present and the plant chromosomes are attached similarly to the microtubule fibers of the spindle.

2. Name a microbe that lacks a cell wall and would find hypotonic environments detrimental.
Answer:
I so I am also a bit confused, but I hope this could answer your question!
Explanation:
The bacteria possess a cell wall composed of peptidoglycan molecule formed by the amino acids called murine. The bacterial cell wall helps in the survival of the bacteria in some extreme condition like when placed in a hypotonic solution.
The hypotonic solution is formed when it has low solute concentration and high water amount when compared. When the bacterial cell will be placed in hypotonic solution then the water will move inside the cell down the concentration gradient as a result of which the bacterial cell will swell but will not burst.
This happens as the cell wall contains expansin protein which allows the cell wall to expand and provides rigidity to the cell.

Introduction
Cellular respiration is one of the most elegant, majestic, and fascinating metabolic pathways on earth. At the same time, it’s also one of the most complicated. When I learned about it for the first time, I felt like I had tripped and fallen into a can of organic-chemistry-flavored alphabet soup!
Luckily, cellular respiration is not so scary once you get to know it. Let's start by looking at cellular respiration at a high level, walking through the four major stages and tracing how they connect up to one another.
Steps of cellular respiration
Overview of the steps of cellular respiration.
1. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made. These reactions take place in the cytosol.
2. Pyruvate oxidation. Pyruvate travels into the mitochondrial matrix and is converted to a two-carbon molecule bound to coenzyme A, called acetyl CoA. Carbon dioxide is released and NADH is made.
3. Citric acid cycle. The acetyl CoA combines with a four-carbon molecule and goes through a cycle of reactions, ultimately regenerating the four-carbon starting molecule. ATP (or, in some cases, GTP), NADH, and FADH_2 are made, and carbon dioxide is released. These reactions take place in the mitochondrial matrix.
4. Oxidative phosphorylation. The NADH and FADH_2 produced in other steps deposit their electrons in the electron transport chain in the inner mitochondrial membrane. As electrons move down the chain, energy is released and used to pump protons out of the matrix and into the intermembrane space, forming a gradient. The protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
These electrons come originally from glucose and are shuttled to the electron transport chain by electron carriers \text{NAD}^+NAD

John Terborgh, tropical ecologist at Duke University, asserts that in order to save tropical forests, citizens of industrial nations are going to have to pay developing countries. Do you agree
Answer:
I do agree
Explanation:
As a personal opinion, I do agree with this statement. Citizens of developing countries use these rain forests for many reasons. One of which is for survival they cut down and use what they need in order to gather the resources that they need and build their habitats. This goes slowly destroying the rainforests. The other reason is that these citizens many times sell the rights to the rainforest land to mining companies that ultimately destroy the rainforest for its resources. The only way to prevent both of these from happening is by paying these developing countries to protect the rainforest instead of profiting from it.

The formation and action of angiotensin II can be summarized as follows: It is synthesized either when blood pressure is ____________ or the ____________ division is activated. It causes a(n) ____________ in resistance, ____________ in fluid output (which helps to maintain blood volume and blood pressure), and an increase in blood ____________ (if fluid intake occurs
Answer:
low, sympathetic, an increase, decrease, pressure
Explanation:
Angiotensin II is a peptide hormone whose primary function is to increase blood pressure by different mechanisms of action including vasoconstriction and sympathetic nervous stimulation. This hormone is produced by the action of the enzyme angiotensin-converting enzyme (ACE). Angiotensin II may act on the central nervous system (CNS) to increase antidiuretic hormone (ADH) levels, and on the arterial smooth muscle cells to trigger vasoconstriction. Angiotensin II induces the release of ADH and aldosterone hormones in order to increase blood pressure. When blood pressure returns to normal values, circulating Angiotensin II levels are decreased by negative feedback.
