DNA controls what you look like and you get this from your parents. Heredity is a trait that you get from your parents that is in your DNA

ex. My dad and myself have brown eyes. That would be both in my DNA and Heredity

ex. My mom had blue eyes. That is just in my DNA because I do not have blue eyes

DNA is the genetic information used to make proteins, and it contains the hereditary traits of organisms. Incase you didn’t know , the two types of DNA are mitochondrial DNA, which you can only get from your mother, and nuclear DNA, which is a combination of both your ancestors DNA.

State the five requirements for a population to be in Hardy-Weinberg equilibrium.
mihalych1998 [28]

When it comes to population evolution and genetics, we cannot fail to cite the Hardy-Weinberg principle which emphasizes that if evolutionary factors such as natural selection, mutation, migration and genetic oscillation do not act on a particular population, the frequencies genotypic proportions will remain constant.

The five requirements for a population to be in Hardy-Weinberg equilibrium are:

  • Large-scale breeding population: For a population to be in Hardy-Weinberg equilibrium, it is important that this population is large, as small populations favor genetic drift (unanticipated fluctuations in allele frequencies from one generation to another).
  • Random mating: In order for the Hardy-Weinberg equilibrium to occur, it is necessary that the mating occur at random, with no preference for certain groups within the population. In this case, we say that the population is in panmixia, that is, they all mate at random.
  • No mutations: Mutations alter the total alleles present in a population (gene pool). Therefore, in a Hardy-Weinberg equilibrium population, no mutations should occur.
  • No gene flow: When there is gene flow due to migration or immigration of individuals, some genes may be included or excluded from the population. Thus, in an equilibrium situation, no gene flow occurs.
  • Lack of natural selection: For a population to be in Hardy-Weinberg equilibrium, natural selection must not be acting on it. If natural selection acts, some genotypes will be selected, modifying the allelic frequencies of the population.

The decision to visit planets other than Earth is not supported by everyone. What would be a good argument against sending human
Ann [662]

Answer:

Sending humans to other planets may cause danger. We dont fully know what these planets are capable of doing. If there is such a thing as life on other planets then we still dont know weather or not life there is friendly or not. They could be harmful, because just as we dont know know exactly who or what they are, they dont know who or what they are either, so its a high chance they may want to defend themselves.

Which structure best makes Bermudagrass successful in preventing soil erosion
valentina_108 [34]

Bermuda grass is successful in preventing soil erosion because the roots of the Bermuda grass can grow deep and it can reach 6 feet deep more on its surface. Also when the Bermuda grass is damaged it can grow back quickly.

Which statement about Earth's rotation and its revolution is correct?
Allisa [31]

Answer:

It takes Earth longer to revolve around the sun than to rotate on its axis.

Explanation:

The vocabulary can be tricky in this question. It is important to remember that the term revolution refers to something moving around a fixed point. In this case, the earth is the object revolving around sun which is the fixed point in the frame of reference.

Now, the earth rotates at a constant speed around its axis. This is what causes the day/night cycle. The earth itself is spinning, therefore we use the term rotate.
