He continued to breed purple-flower producing pea plants together over six generations. The results of Ralph's artificial selection are shown above. What did artificial selection do to the population of pea plants? A. caused a new species of pea plant to form B. increased its genetic diversity C. decreased its genetic diversity D. caused a pea plant to exhibit a new characteristic
Answer:
C
Explanation:
The correct answer would be that artificial selection decreased the genetic diversity of the pea plant.
Genetic diversity is a measure of the number of traits or characters.
Initially, the breeding produced a considerable population of both white and purple flower offspring. But as time goes on, the population of purple flower offspring increased while that of the white flower decreased till it eventually reached zero.
Thus, artificial breeding reduced the number of traits in the population of the offspring from two to one - a case of reduction in genetic diversity.
The correct option is C.

c

A. reproduction
B. oxidation
C. respiration
D. perspiration
Answer:
A. reproduction
Explanation:
X- it's not oxidation because oxidation is just a reaction in which atoms of an element lose electrons
X- it's not respiration because it's literally just taking a breath; breathing
X- it's not perspiration because perspiration is just sweating

Explanation:
I got it right on study island
Jennifer is trying to determine the blood type of her parents for biology class. She knows that her blood type is B. In such case her father may have blood type A,B, AB, and O. Thus, option C is correct.
What is blood group?The three alleles that are A, B, and O are mainly responsible for controlling the major blood groups such as A, B, and AB, respectively. Due to this fact that humans are considered as diploid, each genotype could only include the maximum of two of them. Just to put it another way, just only two of these alleles could coexist in the single cell of the human at given time.
IA, IB, and I are considered as the three distinct alleles that could determine the person's blood type. I has been considered as the most common. These three alleles could be referred to as the A (for IA), B (for IB), and O for the sake of simplicity (for i). Because we receive one blood type allele from our biological mother and one from our biological father, each of us has two ABO blood type alleles.
Therefore, option C is correct.

Between a Black father bear (genotype BB) and a Brown mother bear (genotype bb), they had several baby bears.Black fur allele (B) is dominant overthe brown fur allele (b), what is the probabilityof their offspringhave blackfur?
Answer:
100% or 1
Explanation:
This question involves a gene coding for fur color in bears. According to the question, black fur allele (B) is dominant over the brown fur allele (b). This means that a bear heterozygous for fur color (Bb) will be phenotypically black.
In this question, a black father bear (genotype BB) and a brown mother bear (genotype bb) were crossed, the baby bears will all have a genotype Bb (see punnet square in the attached image). Since all the offsprings of this cross have genotype Bb, this means that 100% will have black fur.

Answer:
B recycyling
Explanation:
The resources which are present in a limited amount and must be used carefully are called nonrenewable resources. For example - petrol, coal, and etc.

The boy asked for the money to buy shoes.
Mrs. Jones taught the boy to have manners.
The answer is the boy asked for money
Answer:
The characters learned to respect each other enough to discuss why the boy tried to grab the purse.
Explanation:
In the short story "Thank You, Ma'am" by Langston Hughes, a young, hungry boy was about to rob a woman of her purse. But as circumstances would turn out, he was unsuccessful in that attempt but then learned a valuable lesson from the very woman he had targeted.
One conflict that was resolved in the resolution was that both of the characters, Mrs. Luella Bates Washington Jones and Roger, learned to respect one another. By her act of inviting him to her home and preparing food for him, Roger also came to respect and trust the woman. It was this faith that helped them discuss the events that led to Roger's failed attempt of robbing Mrs. Jones, and Roger left the house with a sense of appreciation and a change of heart.

Describe how a carbon atom is released from a fossil fuel like coal and travels into the atmosphere as a gas. How does it then end up in living things like plants and animals? Explain how carbon ends up back in the ground. Use the following terms in your typed response: CO2, C6H12O6, atmosphere, lithosphere, hydrosphere, biosphere, carbon sink, carbon source.
Explanation:
Animals and plants need to get rid of carbon dioxide (c02), this process is called respiration. Respiration happens when the plant/animal breaths in air and releases it as carbon, carbon then moves from fossil fuels to the atmosphere where they are burned. When humans burn fossil fuels to power cities, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.
