Write some differences between unisexual and bisexual organisms ​
Reika [66]

Answer:

Unisexual and bisexual organisms are differentiated based on the reproductive systems they posses. Unisexual organisms have separate sexes male or female. Male and female reproductive systems are present in different individuals hence unisexual organisms produce male or female gametes but never both. Bisexual organisms have both male and female reproductive systems within the same individual. Hence, they are capable of producing both types of gametes. Some flowers are unisexual, and they possess only pistils or stamens. Some flowers are bisexual, and they possess both stamens and pistils together. This is the difference between unisexual and bisexual organisms.

Earth's early atmosphere was primarily composed of
Paul [167]

Answer:

The correct answer is ''carbon dioxide, water vapor and nitrogen.''

Explanation:

About 4.5 billion years ago, Earth was a very geologically active planet. So many volcanic fumes formed the primitive atmosphere, which was mostly made up of water vapor, carbon dioxide, sulfur, and nitrogen. At this point, oxygen was barely present and the oceans did not yet exist. The primitive atmosphere is the one before the Precambrian, it was reductive, that is, it lacked free oxygen, and only had ammonia, methane and hydrogen, the high temperature of the atmosphere in its early stages facilitated the reaction of these gases to form organic compounds from which life may have emerged. UV rays passed, because ozone did not exist.

What is the relationship among energy, photosynthesis,and respiration? *
Delicious77 [7]

Answer:

Photosynthesis stores energy, and respiration releases energy.

Explanation:

When plants doing photosynthesis, they will catch the energy from sunlight. The reaction then will store the energy by making glucose. Glucose has high energy that can be released by doing respiration.

Respiration will break down glucose using oxygen and the energy stored inside glucose is released. The energy will be used to synthesize ATP and ATP will be used as main energy.
