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.

Which of the following epochs was the warmest?

vlabodo [156]

This question is incomplete. The options are:
a. Oligocene b. Eocenec. Miocened. Pleistocene

Option b is correct. This relates to the Paleocene-Eocene Thermal Maximum (PETM) which occured around 56 million years ago and was similar to modern-day climate change. Warming of more than 5 degrees Celcius occured over 15-20 thousand years because of input of more than 2000 gigatons of carbon into the atmosphere. The PETM resulted in mass deep ocean extinctions and mass terrestrial and shallow ocean diversification.
