If an enzyme in solution is saturated with substrate, the most effective way to obtain a faster yield of products is to:a. add m
Simora [160]

Answer:

a. add more of the enzyme

Explanation:

Enzymes have specific sites to which their substrates bind during the reaction. These sites are called active sites. When all the active sites of all the enzyme molecules present in a solution are bound to the substrate molecules, the enzyme is said to be saturated with the substrate. Under these conditions, more enzyme molecules are to be added to the solution to increase the reaction rate and to obtain the product at a fast rate. The addition of more enzymes will allow more substrate molecules to occupy the active sites and to be converted into the product/s.

Answer:

The circulatory system transports blood throughout the body through the veins. The circulatory system works with the respiratory system because it transports oxygen through the body as well. It works with the digestive system because it transports waste so it can be disposed.

A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cell
Marrrta [24]

Answer:

M phase: 4.8 hr

Prophase: 2.4 hr

Prometaphase: 0.72 hr

Metaphase: 0.24 hr

Anaphase: 0.84 hr

Telophase: 0.6 hr

Explanation:

Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase,  Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:

M phase: 40/200 = 0.2 x 24 hr = 4.8 hr

Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr

Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr

Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr

Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr

Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr

A scientist is observing onion cells and human cheek cells under a microscope. Which observation does she most likely make?
saw5 [17]

The main difference between a plant cell and the animal cell is the presence of cell wall.

In the plant cell, the cell wall is present, but in the animal cell, the cell wall is absent.

Hence, in the onion cells, the cell wall around the cell would be clearly visible, whereas in the case of cheek cell, the cell would only be lined by a cell membrane, a cell wall would not be present.

Further, the plant cell would have the chloroplast, as they perform photosynthesis, but the animal cell would not have chloroplast. Unlike animal cell, the central vacuole in the plant cell is bigger and clearly visible.
