Answer: D. traits
Explanation: Every trait is controlled by at least a pair of gene, one inherited from the mother while the other inherited from the father . An allele is a variant form of a gene that controls a trait. Every gene that controls a trait is made up of at least two alleles. An allele can be dominant or recessive for example, T is a dominant allele for tall height while t is a recessive allele for short height. If a woman with a genotype of Tt crosses with a man with a genotype of Tt, a child that inherited a (T) allele from the mother and a (T) allele from the father and have a genotype (TT) will have a different trait from his sibling that inherited a (t) allele from the mother and a (t) allele from the father and have a genotype of (tt). The child who has a genotype of TT will be tall while his sibling with genotype of tt will be short. This is because each of them inherited different set of allele from the same parents.
Answer: . all of the above
Explanation:
Science has benefited the society by contributing to wide areas of scientific fields like their contribution in medical science, invention of alternative sources of energy, and technological advances.
Medical science: Scientists have conducted many research in order to determine the cause of diseases and their possible diagnostic treatments.
New energy: Scientists have found out energy harnessing technology from renewable resources like water, sunlight and biomass which can meet the energy requirement of human society when conventional resources will not be available.
Technological advances: Scientists have contributed to the development of diversity of machinery which can reduce the human labor.
My best educated guess would be more of earth's freshwater is found underground (aquifers) than in lakes
Answer:
<u>lysosomes</u>
Explanation:
They are spherical sac-like organelles that contain lytic enzymes that destroy aged and unwanted cells. They contain hydrolytic enzymes that destroy GM2, gangliosides a class of glycosphingolipid that are produced by the nerve cells. Mutations in the HEXA gene that leads to the translation of hexosaminidase A causes the genetic abnormality, Tay-Sachs.
