Answer:
Negative Feedback
Explanation:
Negative feedback is a stimulus that cause the system to move in the opposite direction of what has happening. For example if your are cold, you will shiver in order to create heat that will cause your body temperature to increase. But if you are hot you will sweat which will cause your body temperature to decrease.

One trait a plant can have is either red leaves (R) or brown leaves (r). Another
trait is tall stems (T) or short stems (t). A plant used in a dihybrid cross has
the genotype RrTt. What is the phenotype of this plant?
Answer:
its phenotype will be such that:
·It will have red leaves
·and tall stem.
Explanation:
As red leaves R is dominent allele and tall stem T is also.So the red colour of leaves and tallness of stem will be the dominent traits.

How do objects get energy
Answer:
An object can convert it's potential energy into kinetic energy. For example see the below figure, where potential energy of water has been converted into kinetic energy. A moving body can transfer some of its energy to set another body into motion. ... So, object what you are speaking about is nothing but energy (mass).

Explanation:
There are almost 500 naturally occurring variants of hemoglobin. Most are the result of a single amino acid substitution in a globin polypeptide chain. Some variants produce clinical illness, though not all variants have deleterious effects. Identify the variant or variants that can be described by each of the three statements by placing the letter corresponding to the statement next to the variant. Statement B may describe more than one variant, and a variant may be described by more than one statement. At least one variant will not match any description. A. The Hb variant least likely to cause pathological symptoms. B. The variants most likely to show pI values different from that of HbA on an isoelectric focusing gel. C. The variant most likely to show a decrease in BPG binding and an increase in overall affinity for oxygen.
Hello. This question is incomplete. You forgot the following answer options:
HbS (sikle-cell HB): substitutes a Val for Glu on the surface.
Hb Memphis:Substitutes onde unchanged polar residue for another of similar size on the surface.
HbMilwaukee: Substitutes a Glu for a Val.
HbPhilly: substitutes a Phe for a Tyr, disrupting hydrogen bondingat the α1β1 interface.
Hb Providence: substitutes an Asn for a Lys that normally decrease in BPG binding and an increase in overall affinity for oxygen B C projects into the central cavity of the tetramer
Answer:
HbS (sikle-cell HB): substitutes a Val for Glu on the surface. (B)
Hb Memphis:Substitutes onde unchanged polar residue for another of similar size on the surface. (A)
HbMilwaukee: Substitutes a Glu for a Val. (B)
HbPhilly: substitutes a Phe for a Tyr, disrupting hydrogen bondingat the α1β1 interface. (B)
Hb Providence: substitutes an Asn for a Lys that normally decrease in BPG binding and an increase in overall affinity for oxygen B C projects into the central cavity of the tetramer (BC)
Explanation:
The above phrases reveal information about some of the natural variants of hemoglobin, which as the question above informs, can have more than 500 variants.
Most of these variants occur due to structural changes that were caused by amino acid substitutions within the nucleotide sequences, which ends up modifying the entire protein, often interfering with its functions, depending on the extent of the mutation and where it happened.

Put the following carbohydrates in order from smallest to largest: cellulose, fructose, sucrose.
Answer:
fructose∠sucrose∠cellolose.
Explanation:
Fructose is monosacharaide composed of 12 carbon atoms.
sucrose is disacharaide composed of a glucose and a fructose .
while celolose is a poly sacharide made of milions of glucose molecules.
The order of the following carbohydrates from smallest to largest is as follows:
Fructose < Sucrose < Cellulose. What are Carbohydrates?Carbohydrates may be defined as the type of large organic biomolecules that primarily consists of carbon, hydrogen, and oxygen atoms.
These molecules are energy-deriving molecules that deliver energy to living organisms through the process of breakdown. Carbohydrates are one of three essential and main nutrients found in foods and drinks along with protein and fat.
Fructose is a type of sugar known as a monosaccharide which is significantly composed of 12 carbon atoms. While sucrose is an example of disaccharides. It is also a type of sugar that is generally composed of glucose and fructose subunits.
At last, there is cellulose. It is a type of storage sugar that is of polysaccharide nature. Cellulose is an extremely large form of carbohydrate that consists of a number of glucose molecules.
Therefore, Fructose < Sucrose < Cellulose, is the correct order of carbohydrates from smallest to largest units.

You are studying a variety of pea plant that has either red flowers or white flowers. When you cross true-breeding red-flowering plants with true-breeding white-flowering plants, you get all red-flowering plants in the F1 generation. If you then allow the F1 plants to self-ferilize, you observe that 75% of the F2 plants are red-flowering plants, while 25% of the F2 plants are white-flowering plants. Next you make 640 different monohybrid crosses and decide to analyze only the first 8 plants produced from each of these crosses (i.e. a total of 5120 progeny plants total). How many of these crosses would be expected to produce 6 red plants and 2 white plants?
Answer:
199 or 200
Explanation:
The computation of the number of these crosses is shown below:
P (red) = 75% = a
P (white) = 25% = b
Now determine the probability of 6 red + 2 white and then multiplied it by 640
Now use the binomial theorem
now the required probability is
= 28 × (0.75)^6 × (0.25)^2 × 640
= 199.25
= 199 or 200
hence, the number of corsses is 200
The pH of a solution determines the charge of certain R groups. The pH of pineapple fruit ranges from 3.5 to 5.2. Predict the effect on the activity of bromelain if it is used in a product with a pH of 11. Provide reasoning for the prediction
Answer:
Such change in pH will ultimately change its function.
Explanation:
Hello,
In this case, it is widely known that slight or noticeable changes in pH will affect the present interactions among amino acids in the bromelain (protein-digesting enzyme compound derived from pineapple's stem, fruit, and juice), which are able to change the way it folds and therefore its shape and its function since it will start catalyzing different process due to the different pH.

Answer:From early unicellular organisms that formed in salty water environments to complex organisms that live on land away from water, cells have had to protect a homeostatic internal environment favorable to the biochemical reactions necessary for life. In this chapter, we will outline what steps were necessary to conserve the water within our cells and how mechanisms have evolved to maintain and regulate our cellular and organismal volume. We will first examine whole body water homeostasis and the relationship between kidney function, regulation of blood pressure, and blood filtration in the process of producing
