Answer:
One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin. Let (S) represent the dominant allele, and (s) represent the recessive allele. Only (ss) individuals will express a smooth chin. To determine the probability of inheritance of a smooth chin (or any other recessive trait), the genotypes of the parents must be considered. If one parent is heterozygous (Ss) and the other is homozygous recessive (ss), then half of their offspring will have a smooth chin.
Explanation:
Answer:
Option-B
Explanation:
Heredity refers to the passing of the traits from the parents to the offsprings or generation and also known as inheritance and Genetic variation is the difference in the genetic material in population which leads to the formation of a variety of traits.
Since the variation in traits is determined by factors (Gregor Mendel) later called "genes" which are passed on to the offsprings, therefore, the branch of biology which studies the pattern of inheritance and variation is known as "Genetics". Gregor Mendel is known as the Father of Genetics.
Thus, Option-B is the correct answer.
Answer:
The correct answer is - decreases. direct.
Explanation:
Altitude is a distance measurement of distance in a vertical manner or how high something from the sea level. It helps in the height of the mountains and different places.
Air pressure and altitude are the two factors that are in direct relation as the air pressure decreases with the increase in altitude. the gases present in the higher elevations are fewer than the sea level.
The organs represented in the image are the Brain, nerve, and spinal cords that monitor and react to changes in the body and its environment.
<h3>What are Organs?</h3>
Organs may be defined as an assemblage of tissues that structurally construct an operational unit specialized to accomplish a distinct operation and functions in the body of a living organism.
The nerves function in sending and receiving signals to the brain from external stimuli. They give the perception of feeling pain, relaxation, stress, etc to the brain according to the situations.
The complete question is as follows:
The picture shows an organ system in the human body.
Brain, Nerve, and spinal cord.
What do these organs do in the human body?
- They filter pathogens and dead cells out of lymph before it returns to the blood.
- They monitor and react to changes in the body and its environment.
- They release hormones that control the activities of cells and organs.
- They identify and destroy things that are foreign or harmful to the body.
Therefore, the correct option for this question is B, i.e. They monitor and react to changes in the body and its environment.
