when people have a bacterial infection, pyrogens are often released to maintain elevated body temperature, which helps kill the bacteria causing the infection. which answer option is the most likely action of pyrogens on thermoregulation?

Answer:

true

Explanation:

Meiosis halves the number of chromosomes, so out gametes are haploid. During fertilization, the zygote ends up with the "original" number od chromosomes.

The correct option is plasma membrane allows some substances to enter or leave a cell more easily than others.

The cell membrane's selective permeability is its capacity to distinguish between various types of molecules, permitting some to pass while preventing others. This selective quality is somewhat influenced by the inherent membrane diffusion rates of certain compounds.

Orbital period is actually the time a certain astronomical object such as planets takes to complete one orbit (360° revolution) around the another object such as sun or stars. Orbital period is expressed in many units of time, usually in years, days or hours.

The gravitational force is that which attracts any two objects with mass. We basically call this force attractive because it always tries to pull  masses together, but it never pushes them apart from each other. In fact, every object, including we, is pulling on every other object in this entire universe! This is simply nothing but known as Newton's Universal Law of Gravitation.

The frequency of the heterozygous genotype Aa to the relevant part of the Hardy-Weinberg equilibrium equation is 2pq.

If there is a population of 100 individuals and we have a cross between two heterozygous individuals i.e. Aa × Aa A aA AA Aaa Aa

aawe, we see that the proportion of offspring is: AA = 1/4

which corresponds to 25% of Aa = 2/4

which corresponds to 50% of aa = 1/4

which equals 25% Now,

in solving the Hardy Weinberg equilibrium There are two equations.

p + q = 1p² + 2pq + q² = 1

where: p² exists as the frequency of an individual with a homozygous dominant genotype (AA) = 25%2 pq as the frequency of an individual with a heterozygous genotype

(Aa) = 50%q² exists as the frequency of an individual with a homozygous recessive genotype(aa) = 25%So the frequency of the heterozygous genotype Aa to the relevant part of the Hardy-Weinberg equilibrium equation is 2pq.

The correct answer is anaerobic glycolysis.

Anaerobic glycolysis is the process by which glucose is converted to lactate when oxygen is limited.

Anaerobic glycolysis is only an effective energy generation method during brief, intensive activity, producing energy for 10 seconds to 2 minutes. Cells that are unable to generate enough energy through oxidative phosphorylation use anaerobic glycolysis as a substitute. Glycolysis generates 2 ATP in tissues with low oxygen levels by diverting pyruvate away from mitochondria and using the lactate dehydrogenase process.  Anaerobic glycolysis provides for the more rapid synthesis of ATP in rapidly contracting skeletal muscle cells, where energy demand exceeds that which can be provided by oxidative phosphorylation alone.  (Oxidative phosphorylation is around 100 times slower than glycolysis.) Pyruvate cannot undergo oxidative phosphorylation, regardless of oxygen levels, in cells that have no mitochondria at all.
