Positive feedback is most like _____.

Answers

Answer 1

Answer:

Positive feedback is most like adding wood to a burning fire to increase the heat.

Positive feedback is a regenerative feedback process in which a segment of the output is combined with the input for the output to increase more. Components of a positive feedback loop include a stimulus or change, a sensor, a control center and an effector. Examples of positive feedback include the process of labor and childbirth and blood clotting.

Answer 2

Answer: Positive feedback is most like adding wood to a burning fire to increase the heat.

In which phase will crossing-over occur? A. Meiosis II
B. Metaphase II
C. Mitosis
D. Prophase I

Answers

The correct answer is option D. Prophase I

The crossing over is a phenomena, which occur in the cells undergoing meiosis. In the process of crossing over, the exchange of the genetic material takes place between the sister chromatids. This process takes place in the prophase 1 stage of meiosis 1 in the gametes. The exchange of genetic material between chromatids cause recombination, and hence, genetic variation.

Crossing over occurs in the first stage of meiosis which would be Prophase I.

During which phase of meiosis does crossing over chromosomes occur

Answers

Answer:

Pachytene of prophase I of meiosis I

Explanation:

Crossing over is the process of exchange of genetic material between non-sister chromatids of homologous chromosomes. It occurs during the pachytene stage of prophase I of meiosis I. During pachytene, the paired homologous chromosomes exchange genetic material between themselves and add new gene combinations to the daughter cells.

phase where crossing over chromosomes occur is prophase 1

A student placed a disk of filter paper in each of the following solutions: disinfectant 1, disinfectant 2, disinfectant 3, and distilled water. While the four disks were soaking in their respective solutions, she streaked a sterile nutrient agar dish with a culture of E. coli bacteria. Then, she placed each disk carefully onto the nutrient agar dish, placed the lid on the dish, taped it shut, and incubated the dish at 37°C for several days. The diagram shows how the nutrient agar dish looked on Day 1 and Day 4. The shaded portion of the plate on day 4 indicates the bacterial growth. What is the control in the experiment?a. Disk soaked in disinfectant 1
b. Disk soaked in disinfectant 3
c. Disk soaked in disinfectant 2
d. Disk soaked in distilled water

Answers

d. Disk soaked in distilled water
