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.

1. When a consumer eats a producer, 10 percent of the producer's energy is passed on to the consumer trophic level. What happens to the other 90 percent?
A. It is added back to the soil by decomposers.
B. It is used by the producer to pass on to the next trophic level.
C. It is used for cell processes or released as heat.
D. It is consumed and used by the consumer.
2. Why is there less biomass at the top of the energy pyramid?
A. Secondary and tertiary consumers have to consume a lot more food to support themselves, so there are fewer of them.
B. Secondary and tertiary consumers live longer, so there are fewer of them because they reproduce more slowly.
C. Secondary and tertiary consumers are larger, so there are fewer of them.
D. Secondary and tertiary consumers have bigger ranges, so there are fewer of them because they each need a lot of space.
3. Using the ten percent rule, determine how many kilocalories of energy the tertiary consumer tuna will receive.

Consumers are the organisms that depend on others for food and energy for the metabolic process while the producers produce their food at the trophic levels.
The correct options are 1. C, 2. A, 3. A, 4. A and 5. A.
The trophic levels can be explained as:1. In the trophic levels the energy gets decreased as it passes from one level to another because it is used in the cellular process it is released in the form of heat.
2. Secondary and tertiary consumers have to feed a lot and hence, they are fewer in number compared to the producers. They maintain the population and balance out the producer and consumer ratio.
3. According to the 10 % rule of energy transfer, the Tuna will receive 135 Kcal of energy because the energy decrease by 10% as one moves from the lower trophic to the upper levels.
4. The species that are non-native to a place or region are called invasive species hence, the Kudzu plant is the invasive species as it is introduced from Japan.
5. Given,
Energy of Seal = 2,500 Kcal
The energy of polar bear = 375 Kcal
The 10% of 2500 will be 250 and the 5 % 125 thus, 15% is the efficiency.
Therefore, the correct options are 1. C, 2. A, 3. A, 4. A and 5. A.

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.

6 How can you determine the origin of the oxygen released by photosynthesis?
Answer:
because all green plants release oxygen and non- green plants do not release oxygen.
Explanation: One of the first uses of an isotopic tracer in biology was in the determination of the source of the oxygen produced by photosynthesis. Using a heavy isotope of oxygen, 18O, to label one of the two reactants in the photosynthetic process, Samuel Ruben and collegues at UC Berkeley were able to determine that the oxygen gas came not from carbon dioxide, but water.
