Blood is actually 55% plasma and 45% solids (blood cells).
Answer:
abscisic acid
Explanation:
Abscisic acid is a plant hormone also known by the acronym ABA, whose function is growth inhibition and stomatal closure. We can also attribute to abscisic acid the function of delaying seed germination in the process known as vegetable dormancy. Usually the accumulation of this hormone happens at the beginning of the development of some seeds and is related to delayed germination.
Abscisic acid induces seed dormancy, but decreasing levels of this hormone release seeds from dormancy.
Alleles are different versions of a gene
Homologous chromosomes are chromosome pairs. They are<span> alike each other in size and centromere position. The position of the genes on each chromosome is the same, but the genes do not necessarily have the same alleles within.

Answer: A cell is defined as the smallest functional units of the body
Explanation:
These cells are grouped together to form tissues, each of which has a specialised function, example blood, muscles, bone. Different tissues are grouped together to form organs with a special function. For example heart is an organ made up of muscles tissue, connective tissue, nervous tissue and vascular tissue. These tissues work in a coordinated manner and enable the heart to carry out the broader function of pumping blood continuously.
While organs are grouped together to form systems, each of which performs a particular function that maintains the body Internal environment and contribute to the health of the individual. For example the digestive system is responsible for taking in, digesting and absorbing food which involves a number of organs, including the stomach and intestines.
Therefore the statement that 'organs are large structures that keeps us alive" is a correct claim.
