(2 points) The photograph below shows a pill bug. Pill bugs are small animals frequently found in wooded areas near decomposing organic material.

How do autotrophs and heterotrophs benefit one another within an ecosystem?
A. Autotrophs produce oxygen and carbon dioxide for heterotrophs, which produce chemical energy for autotrophs.
B. Autotrophs synthesize ATP and other nutrients for heterotrophs, which produce oxygen for autotrophs.
C. Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.
D. Autotrophs transform chemical energy into radiant energy for heterotrophs, which fix carbon for autotrophs.
Answer: The answer is A,
Explanation:
Answer:
C. Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.
Explanation:
Autotrophs are organisms that conduct photosynthesis. One of the products of photosynthesis is oxygen, which is released into the air. Heterotrophs then take in this oxygen and give out carbon, which then the plants take in and use. This cycle goes endlessly on and on.

Which term refers to one species eating another, such as the red-tailed hawk
eating the prairie dogs?
A. Prey evasion
B. Interspecific competition
C. Predation
D. Herbivory
Answer:
Predation
Explanation:
Predation is the interaction where one organism, the predator (red-tailed hawk), kills and eats another organism, its prey (praire dog).
It is not the other three because:
Prey evasion is when the prey attempts to avoid its predator; however, in this case, the prairie dog is being eaten by the red-tailed hawk.
Interspecific competition is when individuals of different species compete for the same resources in an ecosystem.
Herbivory is the consumption of plant material by animals, and herbivores are animals adapted to eat plants. There are no plants being involved in this scenario.
Why is it advantageous for plants to respond to environmental stresses by going dormant and dropping leaves?
When they lose their leaves they need much less resources to survive (because they don’t need nutrients to support the leaves). For example trees lose their leaves in the winter because the ground freezes up and it’s harder to suck up nutrients.

If there are 600 atoms of Hydrogen in a glass of water, how many atoms of Oxygen
are in that water?
Answer:
300 oxygen atoms
Explanation:
Water = H2O ... this means 2 hydrogen atoms and one oxygen atom
2 hydrogen atoms = 1 oxygen atom
600 hydrogen atoms = ? oxygen atom
600 / 2 = 300
300 oxygen atom

Suppose you have the same mass of water and air. If you want to raise the temperature of water and air from 20°C to 30°C, which substance will require more energy, Q, to do so?
Answer:
Water has a higher specific heat than air. So, it will require more energy to raise the temperature of water from 20°C to 30°C compared to what is needed to raise the temperature of the same mass of air.

The central nervous system (CNS) is composed of the spinal cord and brain. ALL BUT ONE of the choices below describe
function of the spinal cord.
A)
serves as a minor reflex center
B)
conducts motor information from the brain to various
effectors
C)
processes sensory inputs and initiates appropriate motor outputs
D)
conducts sensory information from the peripheral nervous system to the
brain
Answer:
c)
Explanation:
The central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.
What is the central nervous system?The brain and spinal cord make up the central nervous system. The brain directs our thoughts, memories, movements, and emotions. Between the brain and the nerves that run throughout the body, the spinal cord relays messages.
It regulates cognition, personality, memory, emotion, speech, and the capacity to feel and move. The corpus callosum, a band of nerve fibers in the middle of the brain, connects the left and right hemispheres of the brain.
Thus, the central nervous system (CNS) processes sensory inputs and initiates appropriate motor outputs. Therefore, option C is correct.

If a couple had a baby who died and could not have any more babies, but had the opportunity to clone their baby, should they be allowed to clone it?
Well, you can’t clone a baby but, not exactly should you be allowed to do it. Could you clone an alive baby? Yes. There's two specific skills that infertility doctors have that are necessary for cloning. One is micro-manipulation of embryos. In this case, to take a human egg, to remove the nucleus, and then to replace that nucleus with a nucleus from a somatic cell, a body cell of the person who is going to be cloned.
if a couple clone a baby , There's two specific skills are taken by infertility doctors have that are necessary for cloning. One is micro-manipulation of embryos.
what is cloning ?cloning can be defined as the process of producing genetically and phenotypically same organism or cells from a single organism/cell,
the process can be occurred either naturally or artificially. The genotypically and phenotypically similar copies of the original organism are called clones.
Artificial cloning's can be up different types such as Reproductive cloning
Gene cloning, Therapeutic cloning
Reproductive cloning produce genetically identical organisms from a particular organism whereas gene cloning involves producing exact copies of a gene or segments of DNA.
Therapeutic cloning involves the production of embryonic stem cells and create tissues that would replace similar but damaged or worn-out tissues in living organisms.

what are 5 functions of carbohydrates
☁️ Answer ☁️
PROVIDES INSTANT ENERGY TO THE BODY:
This appears to be the primary function of carbohydrates in the body.
Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.
RESERVE FOOD:
Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.
CARBOHYDRATES FORM OTHER BIOMOLECULES:
Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.
DETOXIFICATION OF THE BODY BY METABOLISM:
Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.
SPARING PROTEIN
In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.
Hope it helps.

Use the drop-down menus to complete the statements. In the first step of meiosis I, DNA condenses to form chromosomes . In the second step, ✔ Each pair of chromosomes lines up in the center of the cell . In the third step, . In the final step of meiosis I, .
Answer:
Prophase I, metaphase I, anaphase I and telophase I.
Explanation:
Prophase I is the phase of meiosis I in which DNA condenses to form chromosomes whereas in metaphase I, each pair of chromosomes lines up in the center of the cell. In anaphase I, each pair of chromosomes is separated from one another which is pulled by the spindle to opposite poles of the cell. In telophase I, the duplicated genetic material is separated that leads to two identical daughter cells.

What makes a variation different from an adaptation? Use an example to explain.
Here's an example of what your answer should look like. A bird has red feathers. That’s a variation. That same bird also has hollow bones. That’s an adaptation. The reason that the feathers are a variation but the hollow bones are an adaptation is because...
You come up with an example and figure out the "because" part of the answer on your own.
Answer:
A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.
