Answer:

The correct answer will be-pachytene, prophase I,

Explanation:

Tetrad is the structure formed during the meiotic type of cell division which produces four daughter cells.

The tetrad structure is seen under the microscope during the pachytene substage of prophase I.

The tetrad structure is formed when four sister chromatids are aligned together in a cell before the crossing over event or recombination has to take place. The tetrad formation allows the crossing over to take place in pachytene.

Thus, pachytene, prophase I is the correct answer.

Una parte de la radiación
diamong [38]

La troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.

En la capa de la troposfera, que es la capa más baja de la atmósfera, hay vapor de agua, dióxido de carbono, metano y algunos otros gases que son responsables de la absorción de la radiación infrarroja. Parte de la radiación infrarroja se escapa al espacio, pero una parte es detenida y absorbida por los gases de efecto invernadero presentes en la atmósfera.

Esta absorción de radiación infrarroja por los gases de efecto invernadero contribuye a un aumento de la temperatura de la superficie de la tierra y de la atmósfera. Entonces, podemos concluir que la troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.

In order to improve fat digestion, large fat globules must first be dispersed into smaller droplets in a process called ________
Ludmilka [50]

In order to improve fat digestion, large fat globules must first be dispersed into smaller droplets in a process called <u>emulsification.</u>

<h3 /><h3>What is emulsification in the digestive system?</h3>

Fat emulsification is the process of increasing the surface area of fats in the small intestine by grouping them into small clusters. Large lipid globules are split up into a number of smaller lipid globules. In the chyme, these tiny globules are widely dispersed rather than aggregating into larger groups. Hydrophobic compounds include lipids. Bile salts, are present in bile and have both hydrophilic and hydrophobic sides.

Due to the fact that lipases can only effectively act on lipids when they are broken down into small aggregates, emulsification is crucial for the digestion of lipids. The lipids are converted into fatty acids and glycerides by lipases.

The fossil of a plant reveals that it produced spores that were used for reproduction. Which type of plant was it
natali 33 [55]

Answer;

Seedless plant.


The fossil of a plant reveals that it produced spores that were used for reproduction. It was a seedless plant.


Explanation;

-Seedless vascular plants are plants such as fern and horsetails, liverworts, mosses; which contain vascular tissues, but do not produce flowers or seed.

-These plants reproduce using haploid , unicellular spores instead of seeds.

-These plants have life cycles with two distinct stages; one in which spores are produced and one in which sex cells are produced.

What characteristic would adapt a fruit for wind dispersal?
Marta_Voda [28]
The fruit should have a seed that's light enough to be carried by the wind. Plants like orchids, dandelions, and cottonwood are plants that have seeds that seem like they have "wings" because of the feathery bristles that they have on top of them. These seeds are lightweight and are more often carried out by the wind for pollination.
