A scientist wants to increase the chance of pregnancy in mice. He gives the mice a hormone that causes them to produce more gametes. Which of the following statements justifies which process the cells went through after the hormone injections?
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.

When food becomes scarce, hundreds to thousands of independently living
single-celled amoebas join to form a multicellular mass that will later reproduce.
Which level of the hierarchy of organization does this mass most
closely represent?
Organ system
Tissue
Organ
Molecule
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.
The
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.

1. Imagine that the class had 25% of students with free earlobes and 75% with attached earlobes. What would this suggest about the frequency of the dominant (F) and recessive (f) alleles for these traits in the class population? Explain your reasoning.
Answer:
People with free earlobes carry one or two dominant alleles which means that the free earlobe is a dominant trait over attached earlobes that carries two recessive alleles. The recessive allele is represented by f and the dominant allele is represented by F.
It is given that in a class 25% of students in the class had free earlobes which means either 25% of total alleles are FF or Ff and the rest 75% have ff. It suggests that recessive alleles have more frequency than dominant alleles.
The optimal temperature for the human body is around 98.6’ F. If a young child was running a temperature of 102’ F predict what affect this change in environment would have on the enzymes present in the child’s body. Explain your reasoning.

The first creatures that evolved the first are fish. The first creatures they were evolved before amphibians,reptiles and mammals were fish.
What is the king organism of reptiles ?The king organism of reptiles category is crocodile.
Amphibians, reptiles, mammals and birds evolved after fish where the first amphibians that evolved from a lobe-finned fish ancestor about 365 million years ago. Fishes were the most earliest vertebrates to live on land but they had to return to water in order to reproduce.

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.

Use the diagram below to help you to choose ALLL the CORRECT answers for the question: What are the differences between Meiosis i and Meiosis II?
(MULTIPLE CHOICE)
A In Metaphase I and Metaphase II the chromosomes line up differently because there are a different number of copies
B Telophase and cytokinesis do NOT happen in Meiosis II
C After Meiosis II the 4 daughter cells undergo cell specialization to become eggs or sperm, which does not happen after Meiosis I
D In Prophase I the chromosomes crossover, in Prophase II they do not crossover
Answer:
D In Prophase I the chromosomes crossover, in Prophase II they do not crossover
Explanation:
Meiosis is a type of cell division in which four daughter cells, which are genetically different from one another, are produced. The daughter cells have their chromosomal number reduced by half. Since, the meiotic process aims at producing haploid gametes, it occurs in a series of two-division steps viz: meiosis I and meiosis II.
Meiosis I involves the separation of homologous chromosomes into two daughter cells while the meiosis II involves separation of chromatids to make four daughter cells. One major difference between meiosis I and meiosis II is that in the PROPHASE of meiosis I, a unique process called CROSSING OVER occurs but does not occur in meiosis II (as seen in the attached image).

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.

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.
