Answer:
Properties of life include the use of <u><em>energy</em></u> to power an organisms activities.
Explanation:
Energy is the driving force which allows every cell to perform its functions. Organisms like humans tend to gain energy by the process of cellular respiration. Cellular respiration can be described as a process in which organisms make carbon dioxide and water from glucose (from food) and oxygen (from air). Huge amounts of ATP is also released during this process. In plants, the process of photosynthesis and cellular respiration supplies them with the energy sources.
Answer:
The correct answer is - 2 genes.
Explanation:
The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:
suppose there are only two gene - TT dominant over tt and CC dominant over cc
then the cross would be - RRCC - rrcc
gametes - RC and rc
Cross F1: RrCc
Self cross in F2:
offspring by Punnet cross are:
RRCC -->1/16
RRCc, RrCC .---> 4/16
RrCc, RRcc, rrCC--->6/16
rrCc, Rrcc--->4/16
rrcc ----> 1/16
thus, the correct answer is 2 genes
Humans have 22 chromosome pairs and two sex chromosomes. Females have two X chromosomes; males have an X chromosome and a Y chromosome. ... In humans, animals, and plants, most chromosomes are arranged in pairs within the nucleus of a cell. Humans have 22 of these chromosome pairs, called autosomes.
