Natural selection is a type of evolution that allows organisms to adapt into the environment they're in for survival.
<u>Answer</u>:
- The possible genotypes of the children are Hh and hh.
- The probability of genotype Hh = 1/2
- The probability of genotype hh = 1/2
<u>Explanation</u>:
- <em>Autosomal genes</em> are the genes present on any of the chromosomes except the sex chromosomes.
- An autosomal recessive mutation is the mutation in an autosomal gene which only expresses itself in the phenotype in homozygous condition and affects both males and female equally.
- For the given question, let the autosomal gene be represented by H (dominant) and h (recessive)
- According to the question,
Since the <em>mother</em> is homozygous her genotype would be hh and the <em>father</em> is heterozygous so his genotype would be Hh.
The following cross is made to know the genotypes of the children :
hh X Hh--------> Hh Hh hh hh
So the <em>possible genotypes of the children are Hh and hh as shown in the cross. </em>
Note : An image is attached representing the cross in a Punnett square.
- The probability of an event = No. of favourable outcomes/total no. of outcomes
The probability of occurrence of genotype Hh would be = 2/4 = 1/2
Similarly, the probability of occurrence of genotype hh would be 2/4 = 1/2
The complete question is :
Algae are plantlike organisms that live in the water. These algae have been in sunlight for several hours now. What can the algae do because they are in sunlight? What does this mean for the number of energy storage molecules in the algae?The algae can . . .
take in carbon from the air. The carbon is used to make energy storage molecules.
take in carbon from the air. The carbon is used to break down energy storage molecules.
give off carbon to the air. Giving off carbon allows them to make energy storage molecules.
give off carbon to the air. Giving off carbon uses up energy storage molecules.
Answer: Option A
Explanation:
Algae are plant like organism found in water, they are capable of performing photosynthesis.
Th algae in water trap carbon dioxide from the atmosphere( water) in order to convert into energy molecules known as glucose in the presence of sunlight.
This means the number of energy storage molecules in the algae increases after photosynthesis.
This is how the algae uses sunlight in order to prepare glucose from them.
Answer:
The plants root soak up nutritions and soak up water.

Answer:
The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called ____
The answer is "dorsal root ganglia"
Explanation:
Explanations of some terms
Sensory neurons:
Sensory neurons, also known as afferent neurons, have cell bodies that are located in the dorsal ganglia (also known as spinal ganglia) of the spinal cord. Most sensory neurons have one axon which is split into two branches, they transmit impulses toward the spinal cord.
Spinal cord:
The spinal cord is a tubular structure composed of nervous tissue housed within the vertebral column, runs from the base of the brain to the lower spine. Spinal cord is a component of the Central Nervous System that serves as information highway the between brain and the body which Integrates and processes information. It can function with the brain and can also function independently of the brain.
Dorsal root ganglia:
Dorsal root ganglia also known as dorsal ganglia originated as bipolar cells. They exists within the peripheral nervous system and they have special nerve cell clusters that aid in transmitting the sensory messages of pain and touch. The dorsal root ganglia receive information from sensory receptor organs and transmitting the information to the central nervous system.
