Answer: There re two different types of phenotypes in the offsprings that is Round yellow and Round green.
Explanation-
As per the Mendelian inheritance, Round shape and yellow color of pea are dominant over wrinkled shape and green color of pea.
According to the question, genotypes of parents are- RrYy ( heterzygous for round and yellow) and RRYy ( homozygous for round and heterozygous for yellow).
The first parent can produce four different gametes that is RY, Ry, rY, ry whereas the second parent will produce only two types of gametes that is RY and Ry.
When they are crossed, they will produce two different phenotypes in the offsprings.

Answer:
The answer is Angiosperms and gymnosperms
Wine, beer, and bread with alcohol fermentation. (not meant to be inappropriate.)
The answer is resting. At respiting potential, the inside of a neuron
is slightly negative compared to the outside. The potential difference is usually
about -70 mV. This is due to
accumulation of Na+ ions K+ ions on the outside and Cl- ions on the inside of the axon.
Answer:
B. only chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors
Explanation:
Receptors are chemical structures, that receive and transduce signals that may be integrated into biological systems.
Receptors that can be found in the mouth include: chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors.
<u>Chemoreceptors</u>
These are receptors that detects chemical stimuli, either molecules or ions dissolved in liquids. An example would be our taste buds in the mouth, because they respond to specific molecules or ions in our ingested food.
<u>Thermoreceptors</u> responds to changes in temperature. These receptors are present in the oral cavity, skin and hypothalamus.
Mechanoreceptors are receptors that respond to distortion of the plasma membrane that occurs due to touch, pressure, vibration, stretch, stress or strain
. They can be found in the mucosae of ginviva (gum), cheek, tongue and soft and hard palate.
<u>Nociceptors</u> are receptor responds to painful stimuli. The purpose of nociceptors is to inform the body of injury, damage or threat of damage to body tissues so that a response may be made. They can be found in the tooth pulp and within dentine cavity.
