Which diagram best represents the cycling of respiratory and photosynthetic gases in green
Sedbober [7]

Answer:

The correct answer is - option D.

Explanation:

In algae or any other photosynthetic organism, there is the internalization of carbon dioxide gas in the reaction with water in the presence of sunlight to produce sugar molecules and oxygen gas in the atmosphere. So, photosynthesis is the process that releases or produces oxygen gas.

In cellular respiration (aerobic) the product of photosynthesis, glucose molecules, and oxygen react to produce the energy and releases carbon dioxide and water as byproducts.

So, the correct answer is - option D.

Predict the outcomes of a plant with 6 diploid chromosomes that fertilized a similar plant in which the egg failed to undergo me
Evgen [1.6K]

Answer:

The correct answer would be - triploid plant.

Explanation:

Triploidy is a condition which can be defined as the 3 set of chromosome in an organism, the extra set of chromosome may be come from the maternal organism or the paternal derived. Maternal derived triploidy known as the digynic while in in the case of the paternal derived called diandric.

In this case the sperm goes under the meiosis so the each gamete will have one chromosome of each set (I I I) while the egg failed to undergo meiosis so the gamete carry complete set of chromosome ( II II II ) after fertilization the outcome will be Digynic triploidy (III III III).

Thus, the correct answer would be - triploid plant.
