Answer:
Human and Social Biology is concerned with the study of the structure and functioning of the human body. It also involves the application of biological principles, knowledge and skills, and technological advances, to the maintenance of health and to solve the problems of living together.
Answer:
<u>B) the branching pattern of the roots</u>
Explanation:
Plant roots function as anchors, food storage and aid in the uptake of water and minerals- other modifications include gas exchange and chemical signaling.
Root systems are mainly classified as taproots, usually found in dicots or fibrous roots found in monocots - some plants are a varying combination of the two systems. While tap roots consist of a larger, vertical main root surrounded by smaller lateral roots, fibrous roots are typically a dense network of roots that grow near the surface of the soil.
Taproots are thought to be more common in plants inhabiting regions experiencing water scarcity, while fibrous roots are thought to grow in more lush, water-abundant regions.
Examples of these roots systems include...
- taproots: dandelions, carrots, turnips
- fibrous roots: grasses, corn
Answer:
#Genetic variations
#If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation
Explanation:
#That is due to natural selection.
They are said to be <span>Homozygous
reason: </span>Organisms that have two identical alleles for a particular trait are said to be homozygous<span> (AA) or (aa). 6. Organisms that have two different alleles for the same trait are </span>heterozygous<span> (Aa).</span>
