olya-2409 [2.1K]

Answer:

The correct answer is option a-"oceanic lowstand".

Explanation:

An oceanic lowstand is defined as a geological phenomenon at which the sea level is at a low point and the continents are mostly emergent. The Earth has been on onceanic lowstands historically. This has been identified by different evidence, including the Gulf Coast rivers formation of braided channels.

<h3>C.Green only</h3>

At low light levels, green leaves are most efficient at photosynthesis. But well yeah, in sunny days, red light will work the same as green light

A student does an experiment for a science fair to study whether temperature affects the timing of a cricketâ€™s chirps. The stu

nexus9112 [7]

The frequency of chirps increases as the temperature increases. The correct option is B. The chirps occur closer together as the temperature increases.

-------------------------------

<h2>Available data:</h2>

<h3>Data recorded by the student </h3>

Day Temperature Average time between chirps (sec)

1 21 2. 5

2 22 2. 6

3 23 2. 2

4 24 2. 3

5 25 2. 0

6 26 1. 8

7 27 1. 9

8 28 1. 8

9 29 1. 4

10 30 1. 2

11 31 1. 5

12 32 1. 1

In this experiment the student recorded the time in seconds between chirps.

We can see that as the temperature increases, in general, the time between chirps decreases.

At 21ºC the time between chirps is 2.5 seconds

At 26ºC the time between chirps is 1.8 seconds

At 32ºC the time between chirps is 1.1 seconds

According to this information, if the average time between chirps decreases with the temperature increase, we can assume that the frequency of chirps increases as the temperature gets higher.

<h3>Options,</h3>

A) The higher the temperature, the fewer chirps there will be in 10 seconds.

Wrong. The number of chirps in 10 seconds will depend, not only on the frequency but also on how long the chirps last. Since the student did not record the time of chirps, we can not make this conclusion.

B) The chirps occur closer together as the temperature increases.

True. The chirps increase in frequency as the temperature increases, so they occur closer together.

C) The chirps become farther apart as the temperature increases.

Wrong. We can see how the time between chirps decreases as temperature increases, meaning that they are closer not farther.

D) There is no relationship between temperature and the time between chirps.

Wrong. If we make a graph we will see the tendency and the relationship between chirps and temperature.

Graphs usually explain the relationship between variables. In this example, the relationship would be inverse.

Answer:

Pancreas secrets two hormones called insulin and glucagon which helps in maintaining the glucose level in the blood.

Explanation:

Pancreas secrets a hormone called as insulin, which helps the cell in absorbing the glucose by reducing the blood sugar and providing glucose for energy. On falling of the sugar level pancreas releases a hormone called glucagon. This glucagon informs the pancreas about the presence of low sugar in blood, after which it releases the stored glucose, and helps in raising the blood sugar level. Alpha cell of pancreas produces glucagon.
