How is temperature regulated in the testes for maximal spermatozoa production?

Biology

Normal development in tests requires a temperature. cremaster muscle contract or relax to move testes toward or away from the body or to maintain the acceptable temperature for testicular.
The body temperature regulation is controlled by the autonomic nervous system under the guidance of medulla oblongata which is in the brain system.

Answer:

The temperature in testicles is controlled by their location and scrotum (its muscle layers)

Explanation:

The testicles in male body is located outside their body. This is so because it regulates the temperature requirement  of testicles to produce spermatozoa and male hormone testosterone is sufficient amount. Since testicle is located outside the body, its normal temperature is 4 to 5 degree lesser than the normal body temperature. Also the scrotum covering the testicles also regulate the temperature for optimum spermatozoa development. There are three layers in a scrotum that helps controlling the temperature –  

a) Tunica dartos (located inside the scrotum) – This layer is temperature sensitive. It relaxes when hot and contracts when cold

b) Cremaster muscle in the spermatic cord – Based on environmental temperature it regulates proximity of testicle to the body

c) Pampiniform plexus – It is the coil of testicular veins that cools the arterial blood entering the testicle

Fisher was found lying on his back. Is it likely that his body was moved after death? Why or why not?
Tpy6a [65]

Answer:

Is it likely that his body was moved after death? The answer is NO

Why or why not?

This is due to postmortem staining seen on his back which would have been observed on other parts of the body if the body was moved after death

Explanation:

Livor mortis: is the stage where the heart stops pumping blood through the circulatory system causing blood accumulation at the lowest point of the body. It's also called postmortem stain.

It helps in judging the time of death for a body, the location and position of the body if it's at the spot.

which of the macromolecules tested in this exercise (proteins, lipids, nucleic acids) were formed by dehydration reactions? expl
aalyn [17]

Large polymers are created during dehydration synthesis, which are typically referred to as biological macromolecules. These compounds include proteins, lipids, carbohydrates, and nucleic acids.

As a result, the dehydration reaction is responsible for the formation of protein, lipid, and nucleic acids.

1. Protein structure

  • Amino acid polymers form proteins. There are four different types of proteins, based on structure.
  • The amino acid sequence of a protein is represented by its primary structure, which is a linear chain.
  • The backbone (main chain) atoms of a polypeptide are arranged locally in space to form the protein's secondary structure.
  • A polypeptide chain's whole three-dimensional structure is referred to as a protein's tertiary structure.
  • The protein's quaternary structure, which is a three-dimensional arrangement of the subunits of a multi-subunit protein.

2. Lipid structure is a crucial element of the cell membrane. The structure is mostly composed of a glycerol backbone, two hydrophobic fatty acid tails, and a hydrophilic phosphate group.

3. Nucleic acids' structure: Nucleotide polymers make up nucleic acids. Each nucleotide is made up of an aromatic base with a N-atom connected to a pentose sugar with five carbons, which is then joined to a phosphate group.

Did the Florida Panther become endangered because of natural selection, genetic drift, or gene flow?
Natalija [7]

Answer:

ALL OF THE ABOVE

Explanation:

Genetic Drift are the changes in allele frequency of a population that result from RANDOM survival or reproduction of individuals with certain characteristics.  Survival or reproduction of those individuals in the face of some environmental change is a matter of LUCK or CHANCE, not because of their phenotype or genotype.

While in Natural selection, the environmental events that affect a population are likely random, but the survival or reproduction of the individuals depends on their phenotypes and genotypes.

Meanwhile, Gene flow is the movement of genes into or out of a population. Low gen flow can lead to low genetic diversity.

Low population which can cause low genetic diversity, poor habitat conditions and habitat loss, road deaths, and commercial development in panther range are constant threats to the Florida Panther's survival.

All these causes are related and therefore affects the Florida Panther.
