Two students studying physiology taste a known "bitter" substance, and both report sensing bitterness. They then sample another
Mama L [17]

Answer:

Student A has a protein receptor capable of detecting a bitter molecule found in that substance, whereas student B lacks that particles protein receptor

Explanation:

The sensory organs helps to respond to the change in the external and internal environment. The five main types of sense organs are eyes, ears, nose, skin and tongue.

Tongue contains different types of taste buds and taste receptors that helps to distinguish between the different types of food. The receptors are mainly responsible for the taste detection. The student B is unable to taste the bitter molecule because they lacks the receptor.

Thus, the correct answer is option (c)

Why do animals in the alpine generally have higher levels of hemoglobin?
deff fn [24]
High-altitude environments present a number of physiological challenges for endothermic animals, as they are characterized by a lower partial pressure of oxygen (<span>) and lower ambient temperatures compared to low-altitude environments at similar latitudes. The reduced </span><span> at high altitude results in reduced oxygen loading in the lungs such that the blood may not carry a sufficient supply of oxygen to the cells of respiring tissues (</span>Bencowitz et al. 1982<span>; </span>Bouverot 1985<span>; </span>Turek et al. 1973<span>). This reduced level of tissue oxygenation can impose severe constraints on aerobic metabolism and may therefore influence an animal's food requirements, water requirements, the capacity for sustained locomotor activity, and the capacity for internal heat production.

Many biological structures are composed of smaller units assembled into more complex structures having functions based on their
oksian1 [2.3K]

The inner membrane of mitochondria contains many proteins, has no pores and is very selective; It contains many enzyme complexes and transmembrane transport systems, which are involved in translocation of molecules. This membrane forms invaginations or folds called mitochondrial ridges, which considerably enlarge the surface for affixing these enzymes. In most eukaryotes, the folds form flattened partitions perpendicular to the mitochondrial axis, but some protists have a tubular or discoid shape. In the composition of the inner membrane there is a great abundance of proteins (80%), which are, moreover, exclusive of this organ, namely:

1. The electron transport chain, consisting of four fixed enzyme complexes and two mobile electron transporters:

  • Complex I or NADH dehydrogenase containing flavon mononucleotide (FMN).
  • Complex II or succinate dehydrogenase. Complexes I and II give electrons to coenzyme Q or ubiquinone.
  • Complex III or cytochrome bc1 that yields electrons to cytochrome c.
  • Complex IV or cytochrome c oxidase that gives off electrons to O2 to produce two water molecules.

2- An enzymatic complex, the H + ATP synthetase channel that catalyzes the synthesis of ATP (oxidative phosphorylation).

3- Carrier proteins that allow ions and other molecules to pass through the membrane, such as fatty acids, pyruvic acid, ADP, ATP, O2 and water. The following mitochondrial transporters may be highlighted:

  • Adenine translocase nucleotide. It is responsible for transporting to the mitochondrial matrix the cytosolic ADP formed during the energy consuming reactions and, in parallel, translocates to the cytosol the newly synthesized ATP during oxidative phosphorylation.
  • Phosphate translocase. Cytosolic phosphate translocation together with the proton to the matrix; Phosphate is essential for phosphorizing ADP during oxidative phosphorization.

What is a cloning vector? a. the laboratory apparatus used to clone genes b. the sticky end of a DNA fragment c. an enzyme that
Sidana [21]

Answer:

e) An agent, such as a plasmid, used to transfer DNA from an in vitro solution into a living cell.

Explanation:

A cloning vector is a naked DNA that can be maintained and into which a foreign DNA can be inserted. A vector needs to be small in size, have restriction sites for endonuclease enzymes and the ability to multiply and express itself at a high rate, without disrupting the host cells machinery. Perfect cloning vectors are DNA molecules from viruses, plasmids and bacterial species such as E.Coli.
