Phenotypically and genotypically there are only two different ratios. If you think of a Punett square...
<span>You could say that a pea plant with the trait for the dominant color green (G) could also carry the recessive trait for yellow (g). So let's say you mate a dominant green, (Gg) with another dominant green, (Gg). You would get 1 (GG), 2 (Gg) and 2 (gg). </span>
<span>Phenotypically (as in physical traitwise), the ratio is 3:1 because you have 3 green colored peas and one yellow. </span>
<span>Genotypically (as in traitwise), the ratio is 1:2:1, because you have 1 (GG), 2 (Gg) and 1 (gg). </span>
<span>So although it's random, for any specific trait there are only 4 different outcomes.</span>
Answer:
Unlike most nonmammalian animals, scorpions are viviparous, giving birth to live young instead of laying eggs. Once fertilized, the eggs are retained in the female's body, where the embryos are nourished in utero for periods varying from several months to a year.
Explanation:
Answer:
The statement that best describes the benefit of studying biology is the ability to intelligently debate issues such as cloning.
Explanation:
Biology encompasses the study of all known forms of life, including their anatomy, organization, functioning and interactions.
One of the advantages of the knowledge acquired through biology is to be able to participate in works and discussions involving subjects related to living beings, including cloning.
The other options are not correct because:
<em> a and c. The </em><u><em>ability to experiment on animals or preserve animals that are extinct</em></u><em> is reserved for scientists with a deep knowledge of biology and its fields.
</em>
<em> d. Understanding the </em><u><em>causes of wheather change</em></u><em> does not correspond to knowledge in biology</em>
Answer:
The study of living things.
Explanation:
Biology is known as natural science which helps to study the life of living things along with some characters such as development in characters, evolution in species, chemical processes inside the body, physical body structure, and molecular interaction between the ions.
Living species such as animals, plants are known as an open system that has the ability to survive by lowering entropy and transforming the energy to sustain stable homeostasis. Biology helps us to identify the basic unit of life which is known as cell and for creation and extinction of living organisms.
The term microevolution represents a predictive theory of how species might change with time.
The term macroevolution assumes that nature can create whole new structures and organisms simply be the environmental constraint.
Evolutionary biology, genetics, aetiology, genetics they overlap with the closely related sciences of ecology.
Ecology seeks to explain the movement of materials and energy through living communities, successional development of ecosystem and processes, adaptation and interactions.
