Below is the response:
<h3>What does seed germination mean?</h3>
Germination is the first stage of a seed's development into a seedling. To germinate, seeds require the appropriate combination of temperature, oxygen, and water. In a state of suspended animation known as dormancy, seeds wait to germinate until the environment is favorable for their survival and growth.
The option missing in the query is:
Dry cotton wool
wet cotton wool
covered with water
The initial conditions needed for a seed to germinate are as follows:
warm temperatures are needed for effective enzyme operation.
water, where chemical reactions can occur.
oxygen, for breathing.
Observations:
Seeds planted here won't sprout because of the dry cotton wool. Since some of the prerequisites are not met, they won't exhibit any modifications. (Water isn't present.)
Seeds placed on wet cotton wool will germinate since all the circumstances are there for germinations to occur.

The gases present at the origin of the earth were believed to be nitrogen (N2), Carbon dioxide (CO2), water vapor (H20), and maybe some carbon monoxide (CO).
<h3>Origin of the earth</h3>
The earth is believed to have originated in what scientists have referred to as the big bang in which several gases were formed.
The gases present at the origin of the earth were believed to be nitrogen (N2), Carbon dioxide (CO2), water vapor (H20), and maybe some carbon monoxide (CO). The gases aggregated to form amino acids hence the origin of the initial life forms.

Answer:
1.capsule
2.membrane composed mostly of lipopolysaccharide
3.membrane composed mostly of phospholipids
4.peptidoglycan
Explanation:
The cell wall of gram-negative bacteria is located outside the cell membrane and is composed of a single layer of peptidoglycan, followed by a second membrane composed of phospholipids (often called outer membrane) and finally a lipopolysaccharide layer, these three elements constitute the gram-negative envelope. Also, some bacteria produce a viscous secretion that spreads in the surrounding environment, forming a slime layer known as a capsule.
The moon has less gravity because it is smaller than the Earth.
I think B is the correct answer. Answer choices C & D are about dolphins, but they do not have anything related to negative effects surrounding human and dolphin interaction. A, on the other hand, may seem like a good choice, but then again, the answer is too vague.
