Choose 1 answer:

(Choice A)
A
Random alignment results in the formation of gametes that contain different numbers of chromosomes.

(Choice B)
B
Random alignment results in the formation of some diploid and some haploid gametes.

(Choice C)
C
Random alignment increases the number of possible chromosome combinations in the gametes.

(Choice D)
D
Random alignment increases the likelihood of crossing over between non-sister chromatids.

Answers

Answer 1

Answer: Choice C seems like the most logical answer.

Answer 2

The statement that best explains how the random alignment of homologous chromosomes during meiosis helps generate varied offspring is "random alignment increases the number of possible chromosome combinations in the gametes"

MEIOSIS:

Meiosis is the process by which a single cell produces four daughter cells that are genetically different from one another.

In the meiotic process, pairs of homologous chromosomes align randomly along the metaphase plate in a stage called METAPHASE.

The random alignment is a unique process of meiosis because it helps generate genetic variation in the offspring of sexual reproduction.

This random alignment increases the number of possible chromosome combinations in the gametes.

what determines the physical change form of a substance​

Answers

Answer:

color, shape size  etc

Explanation:

You are a researcher interested in a rare, highly endangered bird species that lives in a very remote area of the Amazonian rainforest. Almost nothing is currently known about this species’ diet, behavior, life-span, breeding system, or its interactions with other species. Use your knowledge of the definition of ecology, the scales at which ecological research is conducted, and experimental design.
1. Which ecological level (or levels) would you focus on in your research? Justify why you would choose this level (or levels), and explain why you would not choose the others.
2. Would you use an observational, experimental, or modeling approach to study this rare bird species? Why would the approach you chose be a better choice than the others for your study?

Answers

Answer:

- Ecological levels to consider in this study: organism, population and community

- Approach: I would use an observational approach to study this bird species

Explanation:

The levels of the ecological organization include the organism, population, community, ecosystem, and biosphere (from simplest to most complex). In this exploratory study, it is imperative to consider: 1-morphological, physiological and behavioral adaptations of the bird species (i.e., organismal-level), 2- size/density/structure of the bird population (i.e., population-level), and 3-interactions between bird population and other populations (i.e., community-level). The higher ecological levels, i.e., ecosystem-level (relationships between the community and abiotic factors ) and biosphere-level (biosphere =  planet Earth), can be in this case disregarded because this study is centered on a focus bird species. Moreover, it is expected to apply an observational strategy because nothing is currently known about the focus bird species. The experimental and modeling approaches seem more suitable to test a particular hypothesis being discussed (it is not the case for this study).

Answers

Answer:

density-dependent, top-down factor

Explanation:

In biology, limiting factors are resources and other conditions in the environment whose presence/availability limit the population growth rate. Density-dependent factors refer to the conditions whose effects on the size/growth of the population vary depending on the population density. Some examples of density-dependent factors include diseases, competition, and predation, etc. These factors can exhibit a positive or negative correlation with the population size. Moreover, bottom-up population control (species limitation by resources) refers to limitations placed by resources allowing growth (e.g.,  food source or habitat), while top-down population control (limitation by enemies), refers to limitations placed by factors that control the death rate in the population (e.g., predation or diseases).

the fertilization of ovules from plant Q by pollen from plant R results in the productions of seeds. What percent of the genes in each offspring's chloroplasts wioll have been inherited from plant R

Answers

Answer:

The correct answer is - zero or 0%.

Explanation:

The fertilization in flowering plants takes place by fusing the pollen of one plant or flower with the ovum of another plant or flower of the same species normally and form a zygote. The zygote gets an equal amount of genetic material from both parent plants by the process f exchange of the genetic material.

The ovum or the egg cell of the plant is considered as the mother and the mother is responsible for the chloroplast And mitochondria of the progeny so in this case, the ovum and egg cell comes from the only plant Q thus, the percentage of chloroplast genes provided via Plant R is 0%.
