Answer:
True
Explanation:
The calcitonin/calcitonin gene-related peptide (CALCA) gene is used to encode different peptide sequences (i.e., calcitonin hormone, calcitonin-related peptides and katacalcin) through alternative RNA splicing. These peptides have different functions. Calcitonin is a hormone mainly produced by cells of the thyroid gland, which is involved in the control of levels of calcium and phosphate in the blood. Moreover, katacalcin is a peptide synthesized from the same precursor of calcitonin (and therefore also mainly produced by cells of the thyroid gland), which is implicated in both calcium regulation and skeletal maintenance. Finally, the calcitonin gene-related peptide (CGRP) is a peptide mainly produced by sensory nerves (type Aδ fibers ), which is involved in pain pathways. The CALCA gene has attracted considerable attention from geneticists because it is specifically expressed in neuroendocrine tissues in normal conditions and abnormally induced in septic conditions (i.e., during the body's extreme response to an infection).

what is ATP ?Adenosine Triphosphate (ATP) is the energy carrier in every living organisms on earth which capture and store energy metabolized from food and light sources in the form of ATP.
ATP is broken down through hydrolysis during energy required by a cell, The high energy bond is broken and removal of a phosphoryl group occurred.
The energy released from this process is used to drive various cellular processes.
ATP is constantly participates in biological reactions and central to the health and growth of all life, transfer energy from one location to another,.

Fluorescent FM dyes partition reversibly into biological membranes without penetrating through them. Suppose that you have neurons cultured in a dish, and you incubate them with an FM dye for a period of time before washing the cells with excess medium to remove the dye.a)You find that if you stimulate the neurons to trigger action potentials during incubation with the dye, the synaptic regions of the neurons remain fluorescent after the wash. Propose an explanation for this effect.b)After you have generated fluorescent synaptic regions by this procedure, suppose that you trigger further action potentials while continuing to wash with excess medium. Would you expect the synaptic regions to lose fluorescence
Answer:
a) Emission observed is due to emission of synaptic vessels
b) Yes
Explanation:
a) Proposing an explanation
The emission observed ( the synaptic regions of the neurons remaining fluorescent ) is due to the emission on the synaptic vessels given that FM dyes have lipid-sensitive emission which can be loaded into a recycled synaptic vesicle
b)
The synaptic regions will lose fluorescence when you continue to wash with excess medium, also the more action potentials triggered the more observed emission. hence the increase in the loss of fluorescence is due to the fact that the emissions are not permanent

The science behind climate change states that human processes may be overwhelming nature's ability to balance and redistribute which element? A. sulfur B. carbon C. uranium 65 D. ammonia
Answer:
B- carbon
Explanation:
carbon is what we break out and yeh
The human processes may be overwhelming the nature's ability to balance and redistribute carbon element in the environment. Thus, the correct option is B.
What are Climate changes?Climate change are the long-term shifts in the temperature and weather patterns in an ecosystem. These shifts in the weather conditions may be natural or artificial, but since the 1800s, many human activities have been found to be the main driving force of the climate change, primarily due to the burning of fossil fuels such as coal, oil, and gas, which produces heat-trapping gases such as carbon dioxide, chlorofluoro carbons, etc.
Most of the human processes are found to be overwhelming the nature's ability to balance and redistribute carbon element in nature.
Therefore, the correct option is B.

how do allosteric enzymes activate and inhibit chemical reactions in a living organism?
Answer:
Allosteric activators bind to locations on an enzyme away from the active site, inducing a conformational change that increases the affinity of the enzyme's active site(s) for its substrate(s). Allosteric inhibitors modify the enzyme's active site so that substrate binding is reduced or prevented.

What structures in the Ammocoetes (lamprey larvae) and adult lamprey are homologous to the gill bars and jaws of the shark (dogfish
Answer: The homologous structure between shark and lamprey is that:
--> Both are fishes and
--> possess skeletons that are at least partially made of cartilage.
Explanation:
The class PISCES belongs one of the five classes of vertebrate with the following features:
--> it is cold- blooded animal.
--> it's body is covered with scales and a layer of slime.
--> it had fins
--> it carries out gaseous exchange by hills.
--> it has a well developed sense of smell
--> it had a two - chambered heart.
The HOMOLOGOUS structures are those features that are present in the lamprey that are also seen in the shark. This can simply be referred to as the similarities between the lamprey and the shark. These similarities include:
--> Both are fishes and
--> both possess skeletons that are at least partially made of cartilage. This is a feature that is lacking in bony fishes such as Tilapia and carp.

There was a study made in a UK forest in where it was calculated the population of red squirrels and grey squirrels. There was a clear competition and by the end of the study, there were only grey squirrels. How the decline of the red squirrel population might affect its native ecosystem??
Answer:
Predators might die out
Explanation:
Since grey squirrels can Camouflage... predators may not eat because the red squirrels die out. And grey squirrels may reproduce more because there is no competition anymore.

A child is born with hemophilia (inherited as an X-linked recessive) and Klinefelter's syndrome to parents who both have normal blood clotting. In which parent (mother or father) and during which round of meiosis (I or II) did the nondisjunction event occur
Answer:
mother
Explanation:
Hemophilia is a sex-linked recessive disorder caused by a mutation in one of the genes responsible for encoding the clotting factor proteins (factor VIII or factor IX), which are located on the X chromosome. Moreover, the Klinefelter syndrome is caused by men having an additional X chromosome. In this case, the nondisjunction occurred from the mother because her gamete included an extra X, it is for that reason that all genes localized on the X chromosome, including the defective gene involved in hemophilia, can cause all of her sons to be affected by the disease in some generation. Thus, sister chromatids did not separate during meiosis (Anaphase II) and caused two copies of the defective allele for the hemophilia trait.
. Luraine, who has blood type o, has a child with blood type B. She claims Will is the
child's father, but he denies this. Will's blood type is AB. How could blood typing
explain that will could, or could not be the father of this child?
If the mother's blood group is O and the father's blood group is AB, then the child's blood group could be A or B. Hence, Will could be his father.
What is blood group?Blood types are based on the presence or absence of specific antigens, which are chemicals that, if they are foreign to the body, may cause an immunological reaction.
Safe blood transfusions depend on proper blood typing and cross-matching since some antigens can cause a patient's immune system to attack the transfused blood.
In case of an emergency, it is crucial to know your blood type. You'll need compatible blood if you ever find yourself in a position where you need a blood transfusion. Blood cells can cluster together due to an incompatible blood group, which can be lethal.
