Answer:
How energy is produced and managed from solar cells?
Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun's core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy
Explanation:
All based on research.
Answer:
The average density of deer in 1923 was 1 deer per 8 acres
Explanation:
Given -
In 1923, the population of deer rose to 
The density of any species is equal to total population divided by total area of the land in which this population is residing.
Where d represents the density
P represents the population and
A represents the area of land
Substituting the given values in above equation, we get -
Thus, the average density of deer in 1923 was 1 deer per 8 acres
Answer:
10 chromosomes
Explanation:
<u>Ten (10) chromosomes</u> would be found in each cell of Arabidopsis thaliana during prophase.
The prophase stage represents the first stage of the mitotic division immediately after the interphase. A diploid cell has 2n number of chromosomes and the ploidy level of a cell remains intact throughout the interphase to the prophase stage of mitosis.
<u>At the prophase, the chromosomes of a cell only condense and become visible under the microscope. Each chromosome is seen as being consisting of two sister chromatids joined together by a structure known as the centromere. </u>
<em>Hence, the number of chromosomes in the cells of Arabidopsis thaliana would remain the same even at the prophase stage of mitosis.</em>
