HURRY please!!

Biology
1 answer:
GREYUIT [131]2 years ago
4 0

Answer:

Before the industrial revolution, there wasn't much pollution/soot, and the moths were mostly light colored. When humans started using machines for everything, soot coated the trees and the light colored moths were easier for birds (predators) to see. The moths became mostly dark colored, because it was better camoflauge.

Now that we have environmental restrictions, there isn't as much soot everywhere. Now moths are mostly light colored again, because the dark moths are easier to see.

Xavier drew a diagram to compare the roles of oxygen and hydrogen in photosynthesis.
Elan Coil [88]

Answer:

Is released into the air through stomata

Explanation:

Oxygen and hydrogen both exists as gaseous molecules in the atmosphere. However, one of them (oxygen) is a product of photosynthesis while the other (hydrogen) is one of the constituents of the molecule that starts the process of photosynthesis.

According to this question, the X used in the attached diagram is the role of oxygen in photosynthesis. Oxygen is released as a product of photosynthesis and goes out of the plant into the air via the STOMATA. Hence, the gas released into the air via stomata is OXYGEN.

3) The oceans and the atmosphere work together through global currents that do what?
belka [17]

Answer:

The correct answer is D)

Cycle energy and matter to support the biosphere as a closed energy system

Explanation:  

The earth as we know it is a closed energy system that is, matter cannot be introduced or removed from it. Sometimes, rare meterites enter into the system with minimal or no disruption.

Also, energy can enter and leave. The energy mostly referenced here is the sun.

Within the earths system, the lithosphere, hydrosphere, and biosphere materials and energy go through a cycle which helps to support life.

For example, water when heated up by the sun rises as vapour from the earth and oceans into the atmosphere where it cools and condenses. When it cools and condenses, it , in the form of rain, comes down on the earth and oceans. As rain falls down to the earth and runs off the rocks, rocks are broken down into smaller fragments and soils.  The hydrosphere comprises of all water bodies on earth. Besides the vapours which are evaporated from the same into the atmosphere, when volcanoes erupt they also send vapourised water into the atmosphere.

So because the earth is a closed system, a change in one sphere effects a change in others. An example is a change in the water cycle.

Cheers

In what location would primary succession most likely occur? An area that was covered by a glacier An area that was in a long dr
Virty [35]
An area that was covered by a glacier

Primary succession is a method of bringing about fertility in infertile land that can not be cultivated. This method usually involves plant species known as "pioneer species", that do not rely heavily on soil nutrients but add nutrients to the soil. The land under the glacier is likely to be void of nutrients and infertile, so primary succession will be needed there the most.
