The plants in this ecosystem are dark in color to absorb sunlight, covered in hair and grow in clumps. What type of ecosystem co
Rufina [12.5K]

Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time. So it could be tundra ecosystem according to the given scenario.

<h3 /><h3>What is tundra ecosystem?</h3>

Tundra ecosystems are treeless areas found in the Arctic and on mountain peaks where the climate is cold and windy and rainfall is scarce.

Much of the year, tundra lands are covered in snow, but summer brings bursts of wildflowers.

Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time.

Thus, the correct ecosystem for the given condition is tundra.

Ribosomes are frequently found on the rough ER just outside of the nucleus. Suggest two reasons that the ribosomes may be found
ollegr [7]

Answer:

Ribosomes are present attached to the rough ER:

1. To easily make proteins that are required inside and outside of a cell.

2. To take up amino acids easily.

3. To make it easier for the mRNA to travel from the nucleus to the ribosomes.

Explanation:

Ribosomes are involved in the synthesis of proteins. The rough endoplasmic reticulum is attached to the nuclear envelope. Hence, this provides an easy pathway for molecules to travel between the nucleus, rough ER and endoplasmic reticulum.

During the formation of a protein, mRNA is formed and the mRNA travels to the ribosomes through the rough ER. The location of the ribosomes makes it easy to take mRNA from the nucleus and amino acids from the cytoplasm and make proteins. When a protein is made, it can be used inside the cell or can be transported to the Golgi apparatus etc.
