(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).

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

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.

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.

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.

c. Both the Porifera and the Cnidaria are asymmetrical.
d. Both the Porifera and the Cnidaria are radially symmetrical.
Answer:
The correct answer is - a. The Porifera are asymmetrical, while the Cnidaria are radially symmetrical.
Explanation:
In biology, symmetry f the body is meant the presence of a pair of organs in an orderly manner that if divide the body each part is a mirror of the other. In the phylum Porifera have asymmetric body plane.
Some animals develop into adults with radial symmetry. Cnidaria adults have radial symmetry type of body plans that eans if they are cut from the middle they divide in the two equal organs into both sides.

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

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.
