Answer: Food and space
Explanation:
Think of the squirrels and birds. They both reside on trees and they compete for the resources like space and food available on the trees.
The fruits that is available on the tress has competition between the birds and squirrels.
Both of the organism also have competition for the space to live. Though birds are not available at the day time but they come to stay on trees at evening and night.
The squirrels have a better grip to fruits in their hands so that the birds cannot get it from them.
Squirrels also move on the land for the food so that they have less competition on trees for food.
Answer:
D) the frequency of rainfall needed for the germination of desert plant seeds
Explanation:
When we talk about abiotic factors, we refer to the non-living factors. The abiotic components of an ecosystem include: Water, air, temperature, light, and the like.
So if we consider it as a limiting factor to population size, this should be the cause of the limitation.
Among all the choices, only D, shows an abiotic factor being the cause of population limiting. Rainfall is an abiotic factor (water), which influences the germination of desert plant seeds, specifically, it depends on the frequency of rainfall.
An enzyme that makes covalent bonds between the sugar of one nucleotide and the phosphate groups in another nucleotide in DNA is ligase.
Enzymes are proteins that accelerate metabolism and chemical reactions in the body. They build some substances and break down others. All living things have enzymes. Our bodies naturally produce enzymes. However, enzymes are also found in finished products and foods.
Amylases: In saliva, amylases help convert starches to sugars. Maltase: Also found in saliva, it breaks down the sugar maltose into glucose. Trypsin: These enzymes break down proteins into amino acids in the small intestine. Your stomach, small intestine, and pancreas make all digestive enzymes.The pancreas is actually the enzyme "powerhouse" of digestion. Produces important digestive enzymes that break down carbohydrates, proteins and fats.

The plasma membrane of the sea urchin egg has receptor molecules that are specific for binding acrosomal proteins .
<h3>What is plasma membrane ?</h3>
Plasma membrane is the outermost covering of the body which selectively permits the entry and exit of different type of materials .
Thus ,it is also called as selectively permeable membrane.it also separates the inner and outer environment of the cell .
It also helps in the diffusion process .
