This is the biological determination system for the sex of an offspring.
aivan3 [116]

Answer:

chromosomes, the X and the Y.

Explanation:

Egg cells all contain an X chromosome, while sperm cells contain an X or Y chromosome. This arrangement means that it is the male that determines the sex of the offspring when fertilization occurs.

While frying some eggs on a frying pan, a friend points to the change that happens to the egg white, which contains a protein ca
Masja [62]

Answer:

Yes because when subject to high heat, the proteins change into varying proteins, which is a chemical change. The heat causes denaturation of the albumin, which hardens and causes the change in color. The protein, when heated, untangle and they will mesh. This will trap the surrounding water, and cause the change in color.

I hope this is enough information...

Dr. Coyne describes an experiment in which dark mice have a higher survival rate than light mice on dark soil when owls are pres
SpyIntel [72]

Answer:

According to Hardy Weinberg equilibrium, allele frequencies in a population remain constant given that there is no evolutionary force acting on the population. In the given case the situation is not ideal since the owls are acting like an evolutionary force for the mice population.

Darker mice will be able to camouflage better in dark soil and hence will be less targeted by the owls. As a result lighter coloured mice will decrease in numbers which will eventually increase the frequency of dark allele in the population, violating the Hardy Weinberg equilibrium.

Which of the following terms should not be used to describe a human with three copies of chromosome 12?
wolverine [178]

Polyploid, Triploid and Euploid terms should not be used to describe chromosome 12

What are chromosomes?

  • The thread-like chromosomes that convey the genetic information from cell to cell are formed of protein and a single DNA molecule.
  • Chromosomes are found in the nucleus of cells in both plants and animals, including humans.
  • There are 46 chromosomes in all, including 22 pairs of numbered chromosomes (autosomes) and one pair of sex chromosomes (XX or XY).
  • Children receive half of their chromosomes from their mother and half from their father since each pair comprises two chromosomes, one from each parent.
  • The dissolution of the nucleus during cell division allows for the visualization of chromosomes under a microscope.
  • Living things have different numbers and shapes of chromosomes.
  • One or two circular chromosomes may be found in most bacteria.
  • All animals and plants, including humans, have linear chromosomes.
  • Actually, there are a certain number of chromosomes for each species of plants and animals.
  • For instance, a fruit fly has four pairs of chromosomes whereas a dog has 39 and a rice plant has 12.
  • The first 22 pairs of chromosomes in humans are known as autosomes, whereas the twenty-third pair is known as the sex chromosomes.
  • Typically, people with two X chromosomes (XX) are biologically female, whereas people with one X and one Y chromosome are naturally male (XY).
  • There are, however, several exception to these laws.

Chromosomes 12:

  • Each human cell typically has 23 pairs of the 46 chromosomes that make up the human genome.
  • One of the pairings is made up of two copies of chromosome 12, one from each parent.
  • Between 4% and 4.5 percent of all DNA in cells are found on chromosome 12, which covers almost 134 million DNA base pairs.

Hence, Polyploid, Triploid and Euploid terms should not be used to describe chromosome 12
