Sheryl is observing ovarian slides taken from a female ape. All the cells show crossover chromosomes. What is this stage?

1 answer:

5 0

The stage at which all the cells show crossover chromosomes is meiotic prophase I. The crossover is the exchange of genetic material between homologous chromosomes. Homologous chromosomes are present in the meiosis I. Regarding the phase of meiosis I, it is expected that the crossover takes place in meiotic prophase I since homologous chromosomes pair up in the prophase.

A man pushes a lawn mower with a force of 200N across 50N meters of his lawn. How much work did the man perform?

krok68 [10]

Work is equal to force times distance or W = Fn x d

In this situation, you would use the following equation:
W= 200N x 50N

W= 10,000N

The man performed 10,000N of work.

The sporophyte of an unknown plant species grows as a separate plant than the gametophyte. The plant produces both female and fl

N76 [4]

Answer:

The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".

Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.

They show alternation of generation in which sporophyte is the dominant stage.

The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.

The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.

The gametes fertilize to produce a diploid zygote.

The zygote divides mitotically and matures into the diploid sporophyte.

astra-53 [7]

Answer:

Different type of the same procedure that takes the place of the kidneys and cleans the blood are mutually all known as osmoregulation.

Explanation:

Along with kidney there are other organs which helps the body to purify blood. These organs are lungs which exchanges carbon dioxide with oxygen and skin which helps in excreting the extra salt concentration from the body. In invertebrate animals the kidney is not present but osmoregulation takes place with the help of organelles and organs like vacuoles, nephridia, antennal glands, salt glands and malpighian tubules.
