Answer:
1-Meiosis:
- Independent assortment: Anaphase I
- Segregation: Anaphase II
2-Mitosis
- Segregation: Anaphase
Explanation:
The Principle of Independent Assortment described by Mendel indicates the mechanism by which different genes get sorted into gametes (i.e., eggs and sperms in mammals) independently of one another, while the Principle of Segregation indicates the mechanism by which gene variants (i.e., alleles) segregate (separate) into gamete cells. In eukaryotic organisms, independent assortment occurs during anaphase I of meiosis, when each pair of homologous chromosomes separate. The assortment of homologous chromosomes during anaphase I explain how genes on different chromosome pairs will segregate independently of one another. On the other hand, the separation (segregation) of sister chromatids occurs in Anaphase II, where gametes carrying single gene variants (i.e., alleles) for each locus are generated.

Answer:
CENTROMERE
Explanation:
The CENTROMERE is the primary constriction region where the identical DNA molecules are most tightly bonded to each other during mitosis and meiosis.
The typical chromosome in metaphase is composed of two sister chromatids joined by the centromere.
Surrounding the centromere, we can find the kinetochores. These are laminar proteinic structures forming a plate where the spindle and kinetochore fibers will join during chromatids separation.
The position of the centromere defines the chromosomes as acrocentric, metacentric, or submetacentric.

Dr. Nachman and his colleagues collected rock pocket mice across 35 kilometers of the Arizona Sonoran Desert, which included both dark, rocky lava outcrops and light, rocky, granite areas. They recorded substrate color, and coat-color frequencies for each location. Each site was separated from any of the others by at least eight kilometers. The researchers trapped a total of 275 mice. Their data are summarized below:

5. Which fur color seems to have the greatest overall selective advantage? Use data collected from both dark-colored and light- colored substrates to support your answer.
6.What environmental change gave a selective advantage for one coat color over another?
7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?
8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.
Answer:
1)
frequencies of light-colored mice ≅ 0.74 frequencies of dark-colored mice ≅ 0.262)
frequencies of light-colored mice ≅ 0.13 frequencies of dark-colored mice ≅ 0.873)
p² ≅ 0.02 q² ≅ 0.74 2pq ≅ 0.244)
q² = 0.13 p² = 0.4 2pq = 0.465) The dark-colored fur seems to have the greatest overall selective advantage
6) Dark lava changed the color of the substrate, from light to dark.
7) Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color.
8) To see if the mice population is evolving. If it is, there will be a change in the allelic and genotypic frequencies over the years. If it is not evolving, the frequencies will keep equal through the years.

atmosphere is a present around the surface of the earth but it is not present around the surface of the Moon why
Answer:
tmosphere is a present around the surface of the earth but it is not present around the surface of the Moon because
This reduces the amount of gravity on the moon. Strong gravity is needed to hold an atmosphere into place. With weak gravity, gases that are emitted from the surface quickly are lost to outer space. Another reason is because the moon does not currently experience plate tectonics and geologic upwelling. Plate tectonics allows for a recycling of crust and convergence and divergence of plates occurs and this leads to volcanoes and gases escaping at the boundaries. The moon is said to be geologically dead.

When one glucose molecule travels through the glycolysis processes, four molecules of ATP are generated. Is it accurate to suggest that glycolysis produces two ATP molecules?
Answer:
No
Explanation:
Technically, this is inaccurate. To say that glycolysis produces two ATP molecules strays from the input of ATP needed. Overall, 4 ATP molecules are produced during glycolysis. However, there is an input of 2 ATP molecules at the beginning. Therefore, the correct statement would be that glycolysis produces 2 net ATP molecules, not that glycolysis produces 2 ATP molecules. (The word net makes a big difference!!).

Explanation:
Have a great summer.
Herding is refer to as the act of bringing individual animals together into a group, maintaining the group, and moving the group from place to place or any combination of those. The description belongs in the area marked "Z" is foraging. Thus, the correct option is C.
What is flocking?A flocking is refer to as the large number of birds, especially those gathered together for the purpose of migration. For example, a large number of animals, especially sheep or goats kept together and migrate.
Foraging behavior includes all the methods by which an animal acquires and utilizes sources of energy and nutrients. This also includes the location and resources consumption, as well as their recapture and storage, within the context of the larger community.
