Explanation:

Root hair cells

Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

Which of the following is NOT a source of dissolved oxygen in the water?
lesantik [10]

Answer:

A. humans going underwater and exhaling

Explanation:

The dissolved oxygen in water refers to the amount of oxygen that is found in water. However, there are various ways that oxygen dissolves in a body of water, these includes;

- Photosynthesis of aquatic plants: Oxygen is the waste product of the photosynthetic process carried out by green plants. Hence, when aquatic plants undergo photosynthesis, oxygen from them tend to dissolve into water.

- Diffusion from the atmosphere: Oxygen from air or atmosphere also dissolves in water

- aeration as water moves over rocks and debris, and from wind and waves

However, humans do not exhale oxygen but carbon dioxide, hence, it is not a source of dissolved oxygen

How is solar energy absorbed and admitted by earths surface?
mylen [45]

Answer:

About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Of the 340 watts per square meter of solar energy that falls on the Earth, 29% is reflected back into space, primarily by clouds, but also by other bright surfaces and the atmosphere itself. About 23% of incoming energy is absorbed in the atmosphere by atmospheric gases, dust, and other particles. The remaining 48% is absorbed at the surface

<h3><u>Answer;</u></h3>

<em>Centrioles </em>

<h3><u>Explanation;</u></h3>
  • <em><u>Centrioles</u></em> are organelles that are only found in animal cells.
  • <u><em>Centrioles are important organelles that functions by helping the process of cell division in animal cells.</em></u> This is by helping the formation of spindle fibers whose role is to separate chromosomes during cell division.
  • Additionally, <em><u>centrioles also play a very important role in celiogenesis, the formation of cilia and flagella on the surface of cells.</u></em> The cilia and flagella enhance the movement of cells.

joja [24]

Answer:

Plants exchange two gases in the atmosphere i. e. oxygen and carbondioxide. Carbondioxide is entered into the plant body through small opening called stomata which are present on the surface of leaves. Carbondioxode is used as a raw material in the process of photosynthesis. Oxygen is produced in the end of photosynthesis process and releases in the atmosphere.
