Internal and external fertilization both _____. _____ Select one: a. produce single-celled zygotes b. occur only among invertebr
Natali [406]

Answer:

Option-A

Explanation:

Fertilization refers to the fusion of the male and female gamete to form the zygote.

When the fertilization occurs inside the organism through insemination then it is known as the internal fertilization and when it occurs outside the organism like observed in the amphibians when male and female gametes fuse in the water is known as external fertilization.

Both are different type of fertilization but share a similarity that is the formation of a single cell called the zygote which grows into the embryo by the mitotic division. The embryo later develops into the organism.

Thus, Option-A is correct.

Compare carbon cycled in the hydrosphere with carbon cycled in the geosphere
Natali [406]

Answer:

C Volcanic activity releasing carbon into the atmosphere.

Explanation:

The statement that best describes the cycling of carbon between the atmosphere and geosphere among the options is volcanic activity that leads to releasing carbon into the atmosphere.

Volcanic activities has to do with the activity of the geological layer of the earth that leads to the emission of gases, eruption of lava or the combination of the two.

When a volcanic activity leads to the release of carbon related gases such as carbon dioxide into the atmosphere, carbon is being circulated between the geosphere (the earth) and the atmosphere (the air).

Hence, the correct option is C.
