Answers
During bronchoconstriction, the smooth muscle that lines the bronchial passages contracts, resulting in a decrease of the internal diameter of the airway and an increase of____resistance to airflow ____
What is bronchoconstriction ?When the smooth muscle around the bronchi and bronchioles constricts, wheezing and shortness of breath result.
When the muscles lining the airways become tense, the process of bronchoconstriction begins. Your airway narrows as a result of the bronchi and bronchioles being squeezed. Numerous airway stimuli can constrict the airway in sensitive patients.Bronchodilators are typically the first step in bronchospasm treatment. There are several ways to get this drug, including pills, nebulizer solutions, and inhalers. In more serious situations, your doctor could advise taking steroids to lessen airway inflammation.Learn more about Bronchi here:

Based on similarities among forelimbs, what bones did the common ancestor of tetrapods probably possess? in your answer, refer to the bones and how they are connected to each other.
Answers
The bones possessed by the common ancestor of tetrapods in forelimbs were the humerus, radius, ulna, carpals, metacarpals, and phalanges.
When we compare anatomy and morphology, we find certain similarities and differences between the organisms that exist today and the organisms that existed several years ago.
Humans, bats, cheetahs, and whales all have the same origin as well as same basic structure of the skeleton but those structures have been modified due to the adaptation to the environment in which they live.
The forelimbs of whales are modified into flippers for swimming while the forelimbs of bats are modified into wings to facilitate their flight.
In the above case, the forelimbs are homologous organs.
Homologous organs are those organs that have a common origin but different functions.
They represent common ancestry.
Thus, the bones possessed by the common ancestor of tetrapods in forelimbs were humerus, radius, ulna, carpals, metacarpals, and phalanges.

In which stage of Meiosis is the amount of DNA reduced? Be very specific.
Answers
During prophase I and metaphase I of meiosis, a chromosome consists of a tetrad (4 chromatids or 4 DNA molecules) and is reduced to two chromatids (2 DNA molecules) by the time metaphase II occurs.
What is meiosis?Meiosis, which generates gametes like sperm or egg cells in sexually reproducing creatures, is a unique sort of cell division since it is a reductional division. It comprises two rounds of division, producing four cells with only one copy of each chromosome as a final product (haploid). Additionally, each chromosome undergoes genetic material cross-pollination between the paternal and maternal copies before division, resulting in novel combinations of the genetic code on each chromosome. Later, during fertilization, the male and female haploid cells created by meiosis will merge to form a cell with two copies of each chromosome once more, the zygote.
Meiosis is characterized by DNA replication, two rounds of cell division, and the production of four daughter cells, each of which has half as many chromosomes as the parent cell. Meiosis I and Meiosis II are the names of the two meiotic divisions. Each chromosome's DNA is duplicated during the S phase of the cell cycle, resulting in two identical sister chromatids that are held together by sister chromatid cohesion until the start of meiosis. The terms "premeiotic S-phase" and "meiotic S-phase" might be used to describe this S-phase. Meiotic cells go through a prolonged G2-like stage known as meiotic prophase just after DNA replication. Homologous chromosomes hook together at this moment and go through genetic recombination, a predetermined process in which DNA may be cut and recombined and then repaired, which allows them to exchange some of their genetic information.

For a fictional neuron, the nernst potential of the mg2 ion is 30 mv. Given this information, where is the ion more highly concentrated?
Answers
If the fictional neuron has a resting membrane potential of -70mV then Mg2+ concentration should be higher outside the cell so that it can contribute positive charge outside the cell. Therefore the correct option is (2) Mg2+ is at a higher concentration outside the cell.
The resting membrane potential (RMP) of the hypothetical neuron must be taken into consideration in order to establish whether the concentration of magnesium is higher within or outside the cell.

As a broad rule, human fingernails grow between 0.5 inches (1 cm) and 4 inches (10 cm) per year, and several items can affect this growth rate.
Where do fingernails originate?Under the cuticle, at the nail root, nails are formed. The old nail cells are pushed out as the fresh nail cells at the nail's root grow. In order to flatten and harden, these aged cells produce keratin, a protein. After that, the freshly produced nail moves along the nail bed, the smooth area under your nails. Human fingernails typically develop at a pace of about 0. Toenails typically grow at a rate of 1.6 mm (0.063 in) each month, which is about half as fast as fingernails at 3.5 mm (0.14 in) per month.

Answers
coenzyme
A co-enzyme such as NADH carries electrons needed for both the Krebs cycle and Electron transport chain. Thus, the correct option is C.
What is Co-enzyme?Coenzymes are the organic compounds which are required by many of the enzymes for their effective catalytic activity. Coenzymes are often vitamins, or their derivatives. Sometimes they can also act as catalysts in the absence of enzymes required for the chemical reaction, but these are not so effective as when used in conjunction with an enzyme.
While enzymes are proteins in nature, coenzymes are small, nonprotein molecules which bind to the proteins and enhance their activity. Coenzymes hold an atom or group of atoms together, allowing the enzyme to work effectively. Examples of coenzymes include vitamin B complex and S-adenosyl methionine.
Therefore, the correct option is C.

What is the conductance of a 1.0-mm-diameter, 10-cm-long blood vessel filled with blood?
Answers
The conductance of the blood vessel is 4.91× 10-6 ohm⁻
Given, here the length of blood vessel, L = 10cm.and the diameter, D = 1mm or 0.1 cm
Then, radius is equals to 0.1/2 = 0.05cm
Now, we calculate cross sectional area, which equals to πr2
A=πr² = π(0.05)²
We know that , the resistivity of blood ties between 80 ohm cm to 240ohm cm.
Therefore, The average resistivity, ρ= 80+240/2ohm cm = 160ohm cm.
Now, we calculate the resistance of the blood by the formula,
R= ρ l/A
R= 160ohm cm × 10cm/ π × (0.05) 2
R= 1600/ 7.854× 103cm2
R= 203.72× 103 ohm.
Now, we caclulate conductance and we know that it is reciprocal of resistance.
So, The conductance is, G= 1/R
G= 1/203.72× 103 ohm.
G= 4.91× 10-6 ohm⁻
Any conductor, including a lightbulb, will block the flow of an electric current; this obstruction is known as electrical resistance and is represented by the letter R. Conductors emit heat when current flows through them because all materials have an electrical resistance.
Conductance is defines as the reciprocal of the electrical resistance . It is denoted by G and it’s unit is ohm- (ohm minus).

During strenuous exercise, anaerobic conditions can result if the cardiovascular system cannot supply oxygen fast enough to meet the demands of muscle cells. Assume that a muscle cell’s demand for atp under anaerobic conditions remains the same as it was under aerobic conditions. What would happen to the cell’s rate of glucose utilization?.
Answers
During strenuous exercise, anaerobic conditions can result if the cardiovascular system cannot supply oxygen fast enough to meet the demands of muscle cells. Assume that a muscle cell’s demand for ATP under anaerobic conditions remains the same as it was under aerobic conditions. Under such circumstances, the cell's rate of glucose utilization would increase a lot.
In the field of science, aerobic respiration is a kind of respiration in which glucose is broken down to release energy in the presence of oxygen. However, if oxygen is not present, then the breakdown of glucose during such circumstances is referred to as anaerobic respiration.
There are 38 molecules of ATP that are formed as a result of aerobic respiration. As a result of anaerobic respiration, only 2 ATP molecules are formed. Hence, if a muscle cell's demand for ATP remains the same in aerobic and anaerobic respiration, then an excessive amount of glucose will be used to meet the requirement in anaerobic conditions.
