Kingdom phylum, there are insects like butterflies
Answer:
In a redox reaction, a reducing agent will donate electrons to another chemical species and then it becomes oxidized.
Explanation:
A redox or oxidation-reduction reaction is a chemical reaction where exchange of electron(s) happen between two chemical species (molecule, atom or ion). In this reaction, one chemical species act as an oxidizing agent while another will be a reducing agent.
An example of redox reaction is given in the attachment.
In a redox reaction, the oxidation number of a reducing agent will be increased, whereas oxidizing agent will be reduced.
Red platelets are too vast to leave any capillaries. As capillaries are just a single cell thick and have thin porous dividers this implies substances can diffuse out of them effortlessly. Helpful substances, for example, oxygen and sustenance diffuse out of the blood in the vessels into the tissue liquid where it is then taken to the cells.
Answer: The correct answer is black because the product of its side and mass is lower.
Explanation: Density of a substance is defined as the mount of matter that can be stored in a given volume.
Mathematically,

As, density is inversely proportional to the volume of the substance.
The substance will be more denser if it has less volume and it will be less denser if the volume is more.
We are given two cubes having different sides.
Volume of the cube is calculated by using the formula:

where, a = side of the cube.
Black: The side of this cube is 2 and volume will be =
Yellow: The side of this cube is 3 and volume will be =
As, the volume of black cube is less. So, this cube will be more denser.
Density of black cube: 
Density of Yellow Cube: 
Hence, black cube will be more denser because the product of its side and mass is lower.
Peat moss allows a soil a greater ability to not just hold water, but to hold it in a way that it's available to plant roots. If a soil is too clay, it will hold water but not give it up. If a soil is too sandy, water drains away too quickly.
