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
Answers
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.

Answers
Answer:
Genetic disorder.
Abnormal cell division.
Explanation:
Down's syndrome is a genetic disorder condition which is caused by the abnormal cell division during the development of the sperm cell or the egg cell. Due to abnormal cell division, the patient receives and extra copy of chromosome which is the cause of Down's syndrome. This is a genetic disorder which means that this disease occur during the formation of baby when the sperm and egg cells fuse together so this abnormal cell division occur in the sperm or egg cell of the patient's parent.

how is sound recorded
Answers
Answer:
Sound is made up of waves in the form of vibrations in the air. Or you can use the signal to record the sound on magnetic tape. This works by a similar process of moving a magnet, but that magnet causes a magnetic tape to gain magnetization in patterns that represent the sound.
In a digital recording system, sound is stored and manipulated as a stream of discrete numbers, each number representing the air pressure at a particular time. The numbers are generated by a microphone connected to a circuit called an ANALOG TO DIGITAL CONVERTER, or ADC.

Answers
A major drawback of using fossil fuels is that they release large amounts of carbon dioxide and other greenhouse gases when burned, which contributes to climate change and global warming. Fossil fuel extraction, transportation, and combustion can also cause environmental pollution and harm to human health. Additionally, fossil fuels are finite resources, and their availability is becoming increasingly limited, leading to geopolitical tensions and conflicts.
Answer: They are harmful
Explanation:
A doctor prescribed Patient X the antibiotic tetracycline to treat an infection involving the bacteria Streptococcus agalactiae. The antibiotic worked, and Patient X regained his health. Several weeks later, Patient K, a family member of Patient X, took tetracycline to treat an infection involving the same bacteria. This time the antibiotic did not work, and Patient K had to seek out another treatment.What statement best explains why tetracycline did not effectively treat Patient K's S. agalactiae infection?A. The generation of S. agalactiae responsible for the first infection were smaller in number and comprised of older and weaker bacteria.B. The generation of S. agalactiae responsible for the second infection descended from bacteria that were selected for their resistance to tetracycline.C. Patient K waited too long to begin treatment, so the bacterial infection had progressed to the point that it was untreatable with an antibiotic.D. Patient K had a rare genetic condition, which causes tetracycline to be ineffective in treating bacterial infections.
Answers
Even if the generation of bacteria was smaller, older or if the infection was going on for a long time, the antibiotics should be able to treat both infections, as its action does not depend on the amount or age of the bacteria. Therefore, A and C are both incorrect.
Rare genetic conditions usually appears in other members of the family as well. And there is no indication of the genetic condition. So D is wrong too.
The most reasonable explanation would be that the bacteria developed the ability to kill the drugs designed to kill them. As they are from the same family, it is possible that K was infected with the offspring of the bacterias in X. Therefore, the correct answer is B. The generation of S. agalactiae responsible for the second infection descended from bacteria that were selected for their resistance to tetracycline.

Information Support Specialistthe three laws of motion
Answers
Answer:
The Newton's three laws of motion are Law of Inertia, Law of Mass and Acceleration, and the Third Law of Motion.
Explanation:
Answer: Hope This Helps!
Explanation:
Newton's First Law of Motion:
Newton's First Law of Motion states that an object in motion tends to stay in motion unless an external force acts upon it. Similarly, if the object is at rest, it will remain at rest unless an unbalanced force acts upon it. Newton's First Law of Motion is also known as the Law of Inertia.
Basically, what Newton's First Law is saying is that objects behave predictably. If a ball is sitting on your table, it isn't going to start rolling or fall off the table unless a force acts upon it to cause it to do so. Moving objects don't change their direction unless a force causes them to move from their path.
As you know, if you slide a block across a table, it eventually stops rather than continuing on forever. This is because the frictional force opposes the continued movement. If you threw a ball out in space, there is much less resistance, so the ball would continue onward for a much greater distance.
Newton's Second Law of Motion:
Newton's Second Law of Motion states that when a force acts on an object, it will cause the object to accelerate. The larger the mass of the object, the greater the force will need to be to cause it to accelerate. This Law may be written as force = mass x acceleration or:
F = m * a
Another way to state the Second Law is to say it takes more force to move a heavy object than it does to move a light object. Simple, right? The law also explains deceleration or slowing down. You can think of deceleration as acceleration with a negative sign on it. For example, a ball rolling down a hill moves faster or accelerates as gravity acts on it in the same direction as the motion (acceleration is positive). If a ball is rolled up a hill, the force of gravity acts on it in the opposite direction of the motion (acceleration is negative or the ball decelerates).
Newton's Third Law of Motion:
Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction.
What this means is that pushing on an object causes that object to push back against you, the exact same amount, but in the opposite direction. For example, when you are standing on the ground, you are pushing down on the Earth with the same magnitude of force that it is pushing back up at you.

What type of succession is this depicting?
Answers
Secondary succession is the kind of succession that might develop in a neighborhood park after the Zombie Apocalypse if the grass wasn't cut anymore and pioneer species would first colonize the bare soil.
Thus, pioneer species like weeds and grasses would colonize the bare soil and disturbed regions in the initial stage of secondary succession. These species can swiftly adapt to a new habitat since they are frequently resilient and rapidly developing.
In secondary succession, the pioneer species are the early settlers multiply and spread, the soil conditions become more stable and draw in additional species like shrubs and tiny trees. These animals are modifying the environment in a way that makes it possible for bigger and more diversified populations of creatures to live in more complicated settings.

4. The endocrine functions is stimulated by this hormone in the anterior pituitary _____ and produces this in the male_____
Answers
1. The exocrine function is stimulated by this hormone produced in the anterior pituitary: follicle-stimulating hormone (FSH), and produces ova (eggs) in the female.
2. The endocrine function is stimulated by this hormone in the anterior pituitary: luteinizing hormone (LH), and produces estrogen and progesterone in the female.
3. The exocrine function is stimulated by this hormone produced in the anterior pituitary: luteinizing hormone (LH), and produces sperm in the male.
4. The endocrine function is stimulated by this hormone in the anterior pituitary: follicle-stimulating hormone (FSH), and produces testosterone in the male.
1. The exocrine function of the reproductive system in females is stimulated by the hormone produced in the anterior pituitary called follicle-stimulating hormone (FSH), which promotes the production of ovarian follicles. The exocrine product in females refers to the release of eggs or oocytes from the ovaries during ovulation.
2. The endocrine function of the reproductive system in females is stimulated by the hormone luteinizing hormone (LH) produced in the anterior pituitary. LH triggers the release of estrogen and progesterone from the ovaries, which regulate the menstrual cycle, promote the development of the uterine lining, and prepare the body for pregnancy.
3. The exocrine function of the reproductive system in males is stimulated by the hormone produced in the anterior pituitary called luteinizing hormone (LH), which stimulates the production of testosterone in the testes. Testosterone is the primary male sex hormone and is responsible for the development of male reproductive organs and secondary sexual characteristics.
4. The endocrine function of the reproductive system in males is stimulated by the hormone follicle-stimulating hormone (FSH) produced in the anterior pituitary. FSH promotes the production of sperm cells (spermatogenesis) in the testes.
Overall, the reproductive system has both endocrine and exocrine functions, with the anterior pituitary gland playing a crucial role in regulating these functions through the production of specific hormones.
