Answer:

The Product

Explanation:

In a chemical reaction the enzyme plays an important role in catalyzing the reaction.

The enzyme has an active site on its structure to which a substrate can come and bind. The active site has a specific shape to which the substrate of complementary shape can come and bind. once the substrate is bound to the active site of the enzyme the reaction takes place and a product is formed. Once the product is formed, product is released from the active site and enzyme remains unchanged at the end of the reaction.

therefore answer is product that is released from the active site

Answer:100% black with rough for both phenotype and genotype;4/4,1

Explanation:

so if a black coat and rough coat are dominant and a guinea pig that is a purebred(homozygous)black coat with rough coat and a homozygous white coat with smooth coat breed the dominant allele will show up for both so as a result since the black coat and rough coat are dominant the result will be 100% black with rough coat.

Answer:

Low calcium levels in the blood

Explanation:

In primary hyperparathyroidism, one or more of the parathyroid glands is overactive. As a result, the gland makes too much parathyroid hormone (PTH). Too much PTH causes calcium levels in your blood to rise too high, which can lead to health problems such as bone thinning and kidney stones. this will happen if parathyroid hormones got high in human body..

Answer:

Low blood calcium

Explanation:

The fact that Thapsigargin is a potent calcium atpase pump inhibitor means that the phase that will see immediate effects is the Relaxation period.

Calcium ATPase pumps help the muscles to relax after contraction which means that Thapsigargin prevents this from happening.

It's effect will therefore be immediately felt in the relaxation period as muscles will be unable to relax.

Options for this question are:

a. Latent period

b. Contraction period

c. Relaxation period

d. All myogram stages are affected

The stem cells are so controversial because it involves the destruction of the human embryo as well as its life for just research purposes only.

Stem cells may be defined as cells that are totipotent and pluripotent in nature and have the prospect to mature into many diverse types of cells in the body.

Embryonic stem cells are the type that is considered most unethical and controversial. The stem cell debate is the contemplation of the moralities of research involving the maturation and use of human embryos for only research methodologies.

Destruction of such important life for our own benefit or research purposes makes the podium controversial.

Answer:

It can Change their Lifespan if it's an insect

Explanation:

When you are exposed to bright light, cells in the retina detect the stimulus and send it to the brain for processing. The brain commands the iris to constrict and decrease pupil size.

The structure that serves as a receptor in this system is Retina

Organisms adapted and evolved the eyes to see the surrounding environment. This ability to see begins when the visible wavelength of light enters the eye through a transparent covering called Cornea. The light enters the cornea and enters the inner of the eye through a round hole known as the pupil.

The light rays then enter the convex-shaped lens in the eye which focuses the beam of light on the back of the eye in the region of the tissue called the retina. The retina contains the photoreceptor cells-rods and cones in which the cone cells have the ability to detect three wavelengths of light especially blue, green and red which help us see various versions of the colour.

These cells convert light energy to chemical energy in the form of the action potential which gets transmitted to the part of the brain associated with the vision. This completes the pathway of the vision.

Thus, Retina is the answer.

Cladistics reconstructs phylogenies by considering shared derived characters between taxonomic groups and the maximum parsimony criterium.

Cladistics evaluate the relationship between different taxa according to shared characters.

The cladistic analysis follows the maximum parsimony criterium.

Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes.

It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.

The sequencing term refers to lists of groups according to their relationship and their shared traits. One group is the sister group of the following one.

Cladistics uses cladograms to represent the common ancestral relationships and the emergence of different characters among the involved groups.

So the cladogram represents the relationship between taxonomic groups according to a derived character.

The derived character is any new trait that a group transmits to its descendants.

Through evolution, the characters change, and new changes are added. When referring to a derived character, we mean that all the subsequent groups in the cladogram carry and share the trait.

According to this framework, cladistics reconstructs phylogenies by considering shared derived characters and the maximum parsimony criterium.
