Fish lay thousands of eggs in one reproductive cycle. What are some factors that prevent the majority of these eggs from developing into fish that then reproduce on their own?

Answers

Answer 1
Answer: Overproduction obviously benefits the survival of fish species greatly.

Summarize the process of fertilization and implantation.

Answers

The process of fertilization involves the deposition of sperms into the vagina to the egg cell during sexual intercourse. Sperms make their way towards the cervix and uterus, and eventually goes to the fallopian tubes. Only a few hundred will remain as they interact with the egg through the use of their heads and movement patterns.

The process of implantation happens when the embryo, the fertimized eggs develops inside the fallopian tube after three days, and then travels to the uterus.

How does conntinental drift cause climates to change

Answers

Continental drift is the moving of continents, and on different parts of the Earth, there are different climates. Therefore, when continents move, the climate will be constantly changing. 

Biologists once assumed that the phenotype of a dominant allele would always be the most common phenotype in a population. Which finding led biologists to a different conclusion? the discovery that most organisms have pairs of like chromosomes and, therefore, a pair of alleles for many traits

the discovery that dominant traits are adaptive and recessive traits help stabilize the population

the discovery of populations in which the phenotype of the recessive allele help a population survive

the discovery that populations undergo evolution when they are exposed to the process of natural selection

Answers

Scientists concluded that the phenotype of a dominant allele would always be the most common phenotype in a population, and that the discovery of populations in which the recessive allele phenotype helps a population survive, and the discovery that populations evolve when they are exposed to the process of natural selection, to understand more we need to know that....

Phenotype distributions

Stabilizing selection. In stabilizing selection, intermediate phenotypes are more apt than extreme phenotypes. For example, medium-green beetles may be better at camouflaging themselves, thus better at surviving in a forest covered with medium-green plants. Stabilizing selection tends to narrow the curve.

Directional selection. An extreme phenotype is fitter than all other phenotypes. For example, if the beetle populationmigrates to a new environment with dark soil and vegetation, dark green beetles can hide better and survive longer than lighter beetles. Directional selectionshifts the curve towards the most favorable phenotype.

Disruptive selection. The phenotypes of the two extremes are fitter than those in the middle. For example, if the beetles migrate to a new environment with patches of light green moss and dark green bushes, both the light green and dark green beetles will be able to hide better (and survive) than the medium green colored beetles. Diversifying selection produces multiple peaks on the curve.

Based on this information, we can conclude that the following statements:

  • The discovery of populations in which the phenotype of the recessive allele help a population survive
  • The discovery that populations undergo evolution when they are exposed to the process of natural selection

All this information is of great importance to understand the phenotypes of populations of living beings.

What Do You Get When You Multiply An Object's mass times the acceleration?

Answers

Hey There!

When you multiply an objects mass times the acceleration, you get the net force. So, net force is, objects mass times the acceleration.
