The answer is pronuclei. A pronuclei is the state of the nucleus of either the sperm or the ovum after the sperm has entered the ovum but the two nuclei have not yet fused. When the sperm enters the ovum, the membrane of the sperm pronuclei dissolves hence leaving no barrier for the two genetic materials to combine.

For each of the following, circle the word that does not belong belong with the rest and then in ONE complete sentence, explain
Vika [28.1K]

Answer: the words that doesn't belong include:

1.) Power

2.) Deforestation

Explanation:

1.) Coal, Oil, Solar and Natural Gas are considered to be sources of energy while POWER is not considered among the rest this is because it's energy in action and not a source of energy.

Coal, oil and natural gas are known as fossil fuels which are the most common sources of energy in industries and homes. These fossil fuels are destroyed by use, that is, they cannot be recovered. Alternative sources of energy is the solar which is gotten from the sun energy. Although not considered a very efficient energy producer, there are already discovered schemes that would provide us with an inexhaustible supply of energy which would also not cause any pollution problems.

2.) Biodegradable, Recycling and Sustainability are means by which pollution is being avoided in the environment. While DEFORESTATION is a process that can cause pollution of an environment, therefore it doesn't fit into the rest of other words.

Biodegradable materials can be broken down by microorganism. Examples include human and animal excreta. Recycling is the reprocessing of waste materials in order to be re-used. This reduces the amount of waste that are sent to incinerators. While sustainability is the maintenance of the ecosystem to remain diverse and productive over time. This could be seen in the preferred use of renewable energy over non renewable energy. But deforestation is the massive cutting down of trees which can cause soil erosion and climate changes leading to the pollution of the environment.
