Why is the rate of movement of the air bubble not exactly the same as the rate of water loss from the plant?

Answers

Answer:

Both depends on different factors.

Explanation:

The rate of movement of the air bubble is not exactly the same as the rate of water loss from the plant because both depends on different environmental factors. The higher rate of movement of the air bubble occurs due to removal of pressure while on the other hand, the rate of water loss from the plant occurs due to temperature. So both air bubble and transpiration process depends on different environmental factors.

The change in Earth’s elliptical orbit around the Sun causes climate change.
The increase of sunspots increases Earth’s temperature.

Answers

Answer: The movement of continents changes wind patterns and ocean currents.

hope this helps!

Explanation:

The best statement that describe the effect of tectonic activity on climate change is that the movement of continents changes wind patterns and ocean currents.

What are tectonic activities?

Tectonic activities includes volcanoes, mountain building, earthquakes and many more.

Tectonic activities are common in plate boundaries where plates converge, diverge or transform.

As a result of the movement of these continental plate, tectonic activities occurs causing earth climate change

Therefore, the movement of this oceanic or continental plates changes the wind pattern and ocean current.

Which of the following are all internal sources of Earth's energy that help drive convection currents below the crust?


A. Kinetic energy from the earth's rotation
B. thermal energy produced by gravity
C. thermal energy from decaying atoms
D. light energy produced in earth's geosphere
E. light energy produced in earth's crust​

Answers

Answer:

D. light energy produced in earth's geosphere

Explanation:

Earth's internal heat budget is very important to Earth's thermal history. The heat flow from the earth's interior to the surface is estimated to be 47 ± 2 terawatts (TW) and originates from two main sources

The internal source of Earth's energy that helps drive convection currents below the crust is D. light energy produced in the earth's geosphere.

Convection current refers to the current that is formed as a result of differential heating. It should be noted that lighter warm material rises while the heavier cool material sinks.

The light energy that is produced in the earth's geosphere is necessary for driving convection currents below the crust. Energy is transferred through the oceans and the geosphere by convection.

If the amount of food or resources available increases, the carrying capacity for an animal would?


Answers

Answer:

Increase

Explanation:

Edpuzzle 2021

The carrying capacity for an animal would increase.

Availability of food resources

Animals are often used by travellers or farmers to carry different types of loads. Such animals include the donkey, buffalo, oxen, elephant, horse, camel and yak.

Such animals derive energy from already produced foods which is required by their body to support the heavy loads carried by them.

When the food or resources available increases the carrying capacity of these animals are expected to increase because more energy is being made available.

5c. Two parents, a heterozygous normal female and a male who is
colorblind, want to know HELP PLSSS!!! the percentage of their MALE offspring that could
be colorblind. What is the expected percentage? *
0%
25%
50%
75%
100%

Answers

Answer and Explanation:

We can assume that being colorblind is a recessive trait.

That means the father has a genotype of both lowercase letters, denoted as bb.

Let's make a chart.

- The Father's Genotype is bb

- The Mother's Genotype is Bb (Because she is heterozygous, which means she has one Dominant trait (B) and one recessive trait (r))

     b               b  

B|   Bb   |   Bb     |

b|   bb    |   bb     |

We get 50% of the offspring to be colorblind, and 50% of the offspring to have normal color vision.

That means the expected percentage is 50%.

Answers

The average mass is 70 kg.

To find the average you need to add up all of the masses and divide by the total number of masses (7).

(55 + 60 + 60 + 65 + 70 + 85 + 95) / 7 =
490 / 7 = 70kg.
