Answer:
Positive and negative feedback differs in that positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal (option d).
Explanation:
Feedback is a process that, applied to biological systems, allows for the changes needed to maintain homeostasis.
Negative feedback loop occurs when a stimulus is presented, producing a change in the body, so the response is to stop the change that is occurring. It is the most frequent type of feedback and has the greatest impact on homeostasis. An example of negative feedback is a decrease in body temperature through sweating. Positive feedback loop occurs when the stimulus produces a change and promotes a response that reinforces that change. The classic example of positive feedback is the secretion of oxytocin, promoted by uterine contractions, whose effect is to increase those contractions, allowing labor.In summary, positive feedback loop acts by increasing an action or signal in the body, while the negative feedback loop reduces or stops the action or signal that occurs.
Answer:
D is correct
Positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal.

Answer:
The heart consists of four chambers organized into two pumps (right and left) for the purpose of providing blood flow to the systemic and pulmonary circulations. The right atrium receives deoxygenated blood from the entire body except for the lungs via the superior and inferior vena cavae!
The heart has four chambers: two atria and two ventricles.
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
The right ventricle pumps the oxygen-poor blood to the lungs.
The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
The left ventricle pumps the oxygen-rich blood to the body.

What exactly is premenstrual dysphoric disorder (PMDD)?
Premenstrual dysphoric disorder (PMDD) is a more serious version of premenstrual syndrome (PMS). PMDD causes severe irritability, depression, or anxiety a week or two before your period begins.
What is Medication-induced depressive disorder?Medications that cause mania or depression appear to alter brain chemicals in some way. Even if the drugs are required to treat the condition, the side effects are unacceptably severe. Accutane, a medication used to treat acne, has been linked to depression.

If a red fur male is crossed with a brown fur female, what percent of the offspring would have the genotype
Answer:
If the brown male had been BB, then all offspring would have been Bb and all brown. However, if the male is Bb as above and you perform a testcross, 50% of all offspring should have the bb genotype and a white phenotype. A testcross to a heterozygous individual should always yield about a 1:1 ratio of the dominant to recessive phenotype. So, both the genotypic and phenotypic ratios

systematically assessing natural compounds’ wound healing potential with spheroid and scratch assays
Systematically assessing wound healing assay is a laboratory technique that is used to study the cell migration and the cell to cell interaction.
This wound healing assay is also known as scratch assay because it is done by the doing a scratch on a cell monolayer and by capturing a image on regular intervals by time to time.
This wound healing is of 4 stages and that are homeostasis, inflammation, proliferation and remodeling.
Homeostasis is the self regulating process in which the organisms try to maintain stability.

Pick only ONE sentence Which sentence from the section shows why the right temperature is important for plants? (A) Temperature can also affect a plant (B) As with any living thing, a plant has an optimal temperature range at which it grows and preforms best (C) It may not be able to take in enough water and nutrients through it's roots (D) Too much heat can cause plant cells to break down, a process called denaturation.
Answer:
The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.
Explanation:
Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.
Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.

Why is photosynthesis so important to living organisms?
Most consumers can convert energy into food, but they can’t make enough of it, so they need producers, too.
Consumers do not usually live in areas where they can get energy, so they have to eat producers to get enough energy.
All living organisms need energy to stay alive, but only producers can directly convert energy into food.
Decomposers take so long to recycle dead and decaying matter that producers have to make up the difference.
Answer:
All living organisms need energy to stay alive, but only producers can directly convert energy into food.
Explanation:
The process of photosynthesis is very important because all living organisms need energy to stay alive, but only producers can directly convert energy into food.
Photosynthesis is the process whereby green plants manufacture their food in the presence of carbon dioxide and water.
They take light energy from the sun and produce food materials. The light energy is converted to chemical energy which are stored in carbon chains as glucose. The chemical energy is then used by other living organisms for their own nourishment.- What is the role of mRNA in expressing specialized structures?

What is mRNA?Messenger ribonucleic acid is a single-stranded RNA molecule that equates to a gene's nucleotide makeup and is read by a ribosome during the protein polymerization reaction.
The function of mRNA is to transport protein details from the nucleus of a cell to the cytoplasm.
Here the protein-making equipment likes to read the mRNA sequence as well as translates each three-base codon into the corresponding amino acid in a burgeoning protein chain.
Messenger RNAs are single-stranded molecules that move genetic information from the nucleus to the cytoplasm, in which proteins are sequenced.
Thus, the correct option is J.

The lumbar and sacral nerves extend inferiorly beyond the end of the spinal cord, they form the Cauda Equina.
What is Cauda Equina?
The cauda equina, a group of nerves near the end of the spinal cord, is so named because it resembles a horse's tail. The top part of the lumbar (lower back) spine is where the spinal cord terminates.
The separate nerve roots that provide the legs and bladder with motor and sensory function continue along the spinal canal at the spinal cord's extremity. These nerve roots continue in the lumbar and sacral region as the cauda equina. These nerves carry signals to and from the pelvic organs and lower limbs.
Cauda equina syndrome (CES) occurs when there is dysfunction of multiple lumbar and sacral nerve roots of the cauda equina.
