2. A volcano erupts 40 miles from an owl’s ecosystem. Ash from the eruption blocks sunlight over your ecosystem for several (7-10) months.
a. Explain what happens within the food web in the weeks that follow the eruption.
b. The ash clears and several more months go by. What do you think will happen to your ecosystem?

Answers

Answer:

a. Sunlight cannot penetrate through the ash clouds. thus photosynthesize won't occur. so the food chain will begin to collapse from the producer and primary consumer. owls will be out thinking that it's night. they will catch fish resulting in an imbalanced ecosystem. the aquatic population will decrease. then it's the doom days for owls. they will emigrate or will die.

b. the ecosystem will restore. that's how nature works.

The volcanic eruption destroyed the owl ecosystem because it prevented the sun's light from entering, so the food web of the ecosystem was destroyed because there was no food, and a new ecosystem will grow after many months.

What is the ecosystem?

The ecosystem has both biotic and abiotic components, and there are many food chains and food webs present in the ecosystem, so the volcanic eruption harmed the ecosystem and killed the populations present, but after many months, when the ashes from the volcanic eruption are cleared, a new population will grow and a new community will be seen.

Hence, the volcanic eruption destroyed the owl ecosystem because it prevented the sun's light from entering, so the food web of the ecosystem was destroyed because there was no food, and a new community will grow after many months.

Answer:

phosophlipids containing a phosophate and 2 fatty acid chains connected by a glycerol molecule.

Explanation:

Phosophlipids containing the phosophate and two fatty acid chains connected by a glycerol molecule.

What is lipid?

Lipid has been defined as an organic compound which has been unable to dissolve in the water. The example of lipids are oils, waxes, hormones, and fats. The main function of the lipid is to just maintain the structure as well as components of cell membranes, storage of site of energy, and important molecule of signaling that utilised in the process of signalling.

Full form of the RNA could be ribonucleic acid and it is a nucleic acid which has been found in almost all cells that are said to be living and RNA is mostly similar to the DNA but there is a difference between RNA as well as  DNA and the difference is that the RNA is single stranded but DNA is double stranded or its structure.

The RNA's backbone has been made up of phosphate group that is arranged in alternating form and the sugar known as ribose other than the deoxyribose which is  present in DNA. There are four bases found  in the RNA and these are adenine, uracil, guanine, and cytosine.

B. What structures are missing from the root hair cells?

Answers

Answer:

The function of root hairs is to collect water and mineral nutrients that are present in the soil and take this solution up through the roots to the rest of the plant. As root hair cells do not carry out photosynthesis, they do not contain chloroplasts.

Explanation:

Mitochondria are missing from root hair cells.

Root hair cells are specialized plant cells found in the roots of plants. Their primary function is to absorb water and minerals from the soil. To achieve efficient absorption, root hair cells have evolved specific structural adaptations.

Root hair cells are elongated and have a large surface area due to their elongated projections called root hairs. This increased surface area enhances their ability to come into contact with the soil, maximizing water and nutrient absorption. However, due to their focus on absorption and their short lifespan, root hair cells exhibit some structural simplifications, such as the absence of certain organelles.

One notable organelle missing from root hair cells is the mitochondria. Mitochondria are the "powerhouses" of cells, responsible for generating energy in the form of ATP through cellular respiration. Since root hair cells are mainly involved in absorption rather than energy production, they have a reduced need for extensive energy generation. As a result, they don't require as many mitochondria as other cells that are highly metabolically active.
