If the individuals in a population mate at random, and if allele h1 is at frequency 0. 60, what is the frequency of h1h1 offspring?.
Answer: Frequencies of two alleles in a gene pool before and after many random matings
Explanation:
Frequencies of two alleles in a gene pool before and after many random matings
The allele frequency of h1h1 in offspring is 0.36 if individuals in the population mate at random, the allele of interest is divided by the total number of copies of all the alleles.
What is the frequency of the allele?The number of times the allele of interest is detected in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to compute the allele frequency.
In a population, if individuals mate at random sampling if h1 has a frequency of 0.60, the frequency of h1h1 offspring is 0.36, in the population.
The frequency of alleles can be expressed as a decimal, a percentage, or a fraction. Allele frequencies vary from 0 (present in no people) to 1 (present in all individuals); in a population, all allele frequencies for a particular gene add up to 100%.
Therefore 0.36 is the frequency of h1h1 in the population for individuals at random mates for h1 frequency of 0.60 in the population.

Explanation:
Nitrites are added to foods to: a. prevent formation of carcinogens. b. change their color. c. improve their nutritive value. d. inhibit rancidity. e. improve their texture.
Nitrites are added to foods to inhibit rancidity. These compounds are used in the food, chemical and pharmaceutical industries.
Nitrites are conservant that prevent the growth of Clostridium botulinum and Listeria bacteria.
These bacteria (Clostridium botulinum and Listeria) are harmful to human health, thereby nitrites must be added to foods.
In meats, nitrites also exhibit some other beneficial properties which include the pink color, antioxidant properties, and savory flavor.

a cockroach is a fast-moving insect. how can an animal with an open circulatory system be so speedy?
Cockroaches have 6 legs and each leg has 3 knees, 18 knees in total. Since the cockroach has so many joints in its legs its can accurately pick up speed when running away from something
An animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.
What is an Open circulatory system?An open circulatory system may be characterized as a type of circulatory system in which blood vessels are completely absent and blood generally flows freely through the cavities of the body. This type of circulatory system is present in arthropods.
Due to the absence of blood vessels, the flow of blood is extremely high in animals that have an open circulatory system. Apart from this, in cockroaches, oxygen is carried out through the tracheal system because of the absence of the lungs. So, it makes the process so speedy.
Therefore, an animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

19. Dax just completed a report on car transportation. He concluded that gasoline
prices will likely rise significantly in the years to come and recommends lower-
cost car transportation for the future. Dax's younger sister, Ava, just completed a
report on air pollution. Ava concluded that gasoline-powered cars cause too
much pollution and recommends that they should not be used in the future.
Which of the following is a solution for the future that would follow both Dax's

A solution for the future that would follow both Dax's and Ava's
recommendations will be to develop cars that run on fuels that pollute less
and cost less than gasoline.
The use of other fuels such as electricity is cheaper than gasoline and will
help tackle the problem of the rising cost of gasoline.
The use of alternative sources doesn't involve the release of gases such as
carbon monoxide etc which pollutes the environment as carbon isn't burned
when electricity is used.

how do you propagate trees
Answer:
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.
Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.
the type of voltage-gated channel that possesses an inactivation gate that temporarily closes after the channel is active is the
The sodium channel possesses an inactivation gate that temporarily closes after the channel is active.
In neurons, sodium channels are responsible for the ascending phase of the action potential (depolarization).
Characteristically, this channel has two transmembrane voltage-dependent gates.When the membrane is depolarized to the threshold, both gates are activated, but since one of them opens rapidly while the other closes slowly, the channel remains open for less than 2-5 milliseconds.Therefore, we can conclude that the sodium channel is responsible for the depolarization and possesses two gates which one temporarily closes after the channel is active.
