Answer: Two Labrador retrievers with black fur can reproduce puppies with yellow fur only when their genotypes are heterozygous dominant for black fur that is- Bb and Bb.
Exaplanation-
As per the given information in the question, black fur is dominant (B) to yellow fur (b). A dominant trait ( depicted by capital letter) masks the expression of recessive trait.
There can be two possible genotypes for black fur that is BB ( homozygous dominant) and Bb ( heterozygous dominant) whereas yellow fur ( which is a recessive trait) can only have one genotype that bb ( homozygous recessive).
When 2 Labrador retrievers with heterozygous dominant genotype ( Bb) are crossed, they is 25% chance of producing a puppy with yellow fur ( bb).
Refer punnett square.
True.
Explanation:
Cardiac muscle and some types of smooth muscle have the ability to contract without any external stimuli.
These muscles are called involuntary muscles.
Involuntary muscle are named so because,these muscles are independent of voluntary control and are controlled by our autonomic nervous system.
These are also known as white or smooth muscle.
Examples, muscles of heart, muscles of alimentary canal etc.
Answer: Option C
Explanation:
The process of photosynthesis can be defined as the process by which the plants and blue green algae make food by the use of water and carbon dioxide are used in the presence of sunlight to get converted into glucose.
The leaves of the plant is the main site for this process and the conversion of light energy into chemical energy takes place here only.
Carbon dioxide that is used in this process is removed from atmosphere which is a greenhouse gas.
Answer:When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.
