Answer:
<h2><em><u>Carbohydrates</u></em><em><u> </u></em></h2>
Explanation:
<em><u>Carbohydrates</u></em> are energy-rich compounds <em><u>made from carbon</u></em>, hydrogen, and oxygen.
Plants and animals use carbohydrates. <u><em>Cells use carbohydrates to get and store energy.</em> </u>
Plants contain cellulose, a carbohydrate, which <em><u>gives them a rigid structure</u></em>.
Answer;
Chromosomes
Depending on the organism, the number of chromosomes in a cell may change.
Explanation;
When a cell in the body divides, it will pass on a copy of its DNA to each of its daughter cells. DNA is also passed on at the level of organisms, with the DNA in sperm and egg cells combining to form a new organism that has genetic material from both its parents.
Each species has its own characteristic number of chromosomes.Humans, for instance, have 46 chromosomes in a typical body cell (somatic cell), while dogs have 78. Like many species of animals and plants, humans are diploid (2n), meaning that most of their chromosomes come in matched sets known as homologous pairs.
The answer is; C
Rhizoids are analogous to roots in vascular plants. They anchor the gametophyte of the moss into the substrate. The rhizoid is also significant in absorbing nutrient from the substrate just like roots. While roots of vascular plants are multicellular, rhizoids may be unicellular or multicellular. Unlike in roots where water is absorbed and passes through the roots up the plant, in rhizoids, water is carried by capillary action in between the rhizoid threads.
