Answer:
C. Meiosis since it produces haploid cellsneeded for reproduction.
Meiosis since it produces haploid cells needed for reproduction justifies the process the cells went through after the hormone injections.
What is Meiosis?This is the type of cell division in which the parent cells produces four unique daughter cells and is involved in reproduction and gamete formation.
The hormone given to the mice to produce more gamete through the process of meiosis will produce haploid cells needed for reproduction.

Briefly describe why plants produce flowers.
Answer:
The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

is the point at which environmental resources limit
population growth.
O A. exponential growth
O B. carrying capacity
O C. population crisis
O D. logistic growth
Answer:
Carrying Capacity
Explanation:
The limits due to environmental resources such as food and mates.
The point at which environmental resources limit population growth is known as the carrying capacity. Therefore, the correct answer is B. carrying capacity.
What is Carrying capacity?Carrying capacity refers to the maximum number of individuals of a given species that a particular environment can support sustainably over time, taking into account the available resources, such as food, water, shelter, and space.
When a population exceeds its carrying capacity, it can lead to resource depletion, environmental degradation, and ultimately, a decline in population size.
Logistic growth is a type of population growth that takes into account the carrying capacity of an environment. It starts with exponential growth and then levels off as the population approaches the carrying capacity.
Population crisis is a term that generally refers to a situation in which a population faces significant challenges, such as food scarcity, disease, or conflict, that threaten its survival.

what are the two product of the krebs cycle
Answer:
Explanation:
For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced. Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles.
Answer:
[tex]\boxed {\boxed {\sf 2 \ ATP, 10 \ NADH, \ 2 \ FADH_2, \ 4/6\ CO_2 }}[/tex]
Explanation:
The Krebs Cycle is one part of cellular respiration, the process that makes energy/ATP for an organism.
In glycolysis, pyruvic acid is made. After, the molecules are changed to acetyl-CoA.
In the Krebs Cycle, oxaloacetic acid combined with acetyl-CoA form citric acid. Enzymes cause reactions, the NAD molecule gains a hydrogen ion (becomes NADH), and FAD also gains hydrogen ions (becomes FADH₂).
Energy is released, so some ATP can be made. Carbon atoms are released as carbon dioxide (exhaled as a waste product).
So, the Krebs Cycle actually has more than 2 products.
For every 2 pyruvic acid:
2 ATP: energy10 NADH: electron carriers in the electron transport chain2 FADH₂: also electron carrier4 CO₂ (Krebs Cycle) + 2CO₂ (converting pyruvic acid): waste gasHurry!

How do researchers hope to understand healthy aging by the study of proteins?
Answer:
Of course, you could scan their driver’s license or look for signs of facial wrinkles and gray hair. But, as researchers just found in a new study, you also could get pretty close to the answer by doing a blood test.
Woman looking at herself in mirror That may seem surprising. But in a recent study in Nature Medicine, an NIH-funded research team was able to gauge a person’s age quite reliably by analyzing a blood sample for levels of a few hundred proteins. The results offer important new insights into what happens as we age.
Explanation:
For example, the team suggests that the biological aging process isn’t steady and appears to accelerate periodically — with the greatest bursts coming, on average, around ages 34, 60, and 78

Organ system
Tissue
Organ

Answer:
The correct answer is - tissue.
Explanation:
In an unfavorable condition like scarcity of food, individual unicellular organism amoeba makes a formation a multicellular mass by aggregation of the cells that reproduce when conditions become favorable. These aggregation of cells known as slime molds.
These molds are more similar to the tissue structure in the hierarchy of organization of a multicellular organism. The tissue is the organization level that is similar to this mass as it is also formedby the cells joined together to perform a particular function.

What is the correct term for microbial action that converts inorganic phosphorous back into organic phosphorus?
The process of _______ refers to the conversion of inorganic phosphorus to organic phosphorus.
Answer:
Mineralization
Explanation:
In biology, mineralization refers to a process where an inorganic substance precipitates in an organic matrix. This may be due to normal biological processes that take place during the life of an organism such as the formation of bones, egg shells, teeth, coral, and other exoskeletons
The process of mineralization is referred to the conversion of inorganic phosphorus to organic phosphorus.
Mineralization is the procedures by which chemicals found in organic matter are decayed or oxidized into forms that plants can use.
The transformation of organic molecules in the soil is driven mainly by its microbiota, which includes fungi and bacteria as well as earthworms.
Mineralization tends to increase the nutrient bioavailability found in decaying organic compounds, most notably nitrogen, phosphorus, and sulfur because they are plentiful.
Carbon mineralization is the transformation of carbon dioxide into a solid mineral, such as carbonate. Whenever these rocks are exposed to carbon dioxide, a chemical reaction occurs.
Thus, the answer is mineralization.

7) Water evaporating from the surface of a lake moves from the?
The water cycle or the hydrological cycle is the motion of water from the surface of the earth into the atmosphere and is cycled into the ecosystem.
Most of the water on the surface of the earth is recycled by the cyclic mechanism of the sun. The processes of evaporation, condensation, and precipitation are responsible for the cyclic motion of the water on earth. The escaping of water molecules due to the wind and or due to rise in temperatures in the lake move above from the surface after attaining low pressure.Thus the vaporized form of water moves away from the lake.
