Which of the statements best describes the process of crossing over during meiosis? Haploid daughter cells trade chromosomes in
Maslowich

Homologous chromosomes pair up and exchange segments of DNA.

Option A

<h3><u>Explanation:</u></h3>

Crossing over is an event of Prophase 1 of meiosis 1. It occurs in the zygotene phase of prophase 1. Here the homologous chromosome pairs get very close together and gets packed within protein coat. The enzymes randomly cut the DNA segments from both chromosomes at same loci and exchange them with each other. This results in the exchange of genes between the two chromosomes. This is how the variation comes to place between offsprings of the same individuals. The crossing over results to form X shaped intersections between homologous pair of chromosomes which is called as chaismata. This phase occurs in pachytene phase and is visible in diplotene phase when the protein coat dissolves.

sergey [27]

Answer:

exposed ovules

Explanation:

Gymnosperms are a type of flowerless plant that tend to produce cones and seeds. This is why the name refers to "naked seed", seeing since the gymnosperm seeds are not positioned within an ovary. Therefore the presence of exposed ovules or the structure that contains the seeds in a place would immediately indicate that this is, in fact, a gymnosperm.

muminat

Complete Question:

The carrying capacity of the environment for a species is determined by:

options:

(a) the reproductive rate of the organism.

(b) the number of organisms of that species.

(c) the state and national wildlife laws pertaining to that species.

(d) the age distribution of that species.

(e) the limited availability of renewable resources in the environment and the environmental resistance to the biotic potential of the organism.

Answer: (e) the limited availability of renewable resources in the environment and the environmental resistance to the biotic potential of the organism.

Explanation: The carrying capacity refers to the highest number of the species that the environment can cater for, in terms of food, space and other necessities that supports life.

Thus, the available of renewable resources (i.e resources that can be reused after consumption e.g water) in the environment, plays as a determinant of the highest number of individuals an environment can support (carrying capacity).

Furthermore, environmental resistance to the biotic potential of the organism, is also a determinant of the carrying capacity of organisms inhabiting that particular environment.
