The percentage of offspring of homozygous dominant will be 50%.

Gregor Mendel, the Father of Genetics, utilised pea plants as a model to study inheritance for a variety homozygous of reasons, the most important of which is that they have a wide range of phenotypic features, such as diverse colours and shapes.

Mendel studied the inheritance patterns of parental genes in terms of how these genetic qualities homozygous manifested in the phenotype of the children, and he classified these traits as dominant (two capital letters; AA) or recessive (one capital letter; AA). He used yellow and green pea plants to test this in the trials. When he crossed yellow and green pea plants, he discovered that the first generation was yellow. This meant that the colour yellow (YY) was dominant, while the colour green (YY) was recessive.

Therefore, the percentage of offspring of homozygous dominant will be 50%.

Although the details of postsynaptic action can be complex, there are simple rules that distinguish between postsynaptic excitation and inhibition.

EPSPs have reversal potentials more positive than the action potential threshold and IPSPs have reversal potentials more negative than the threshold.Excitatory postsynaptic potentials (EPSPs) bring the potential of a neuron close to its firing threshold. Inhibitory postsynaptic potentials (IPSPs) shift the charge across the membrane away from the firing threshold. Postsynaptic potentials undergo spatial and temporal addition. Neurons communicate via electrical currents called action potentials that are either excitatory or inhibitory. Currents responsible for sharing information about one action potential with the next neuron, inhibitory currents reduce the likelihood of such transmission occurring.

Transpiration is affected by several factors. In the above question, the factor which affects transpiration negatively is Humidity, i.e. Option 1.

The process by which the plant body releases water vapors through its aerial portions is known as transpiration. The evaporation of water from a plant component is also referred to as transpiration. It is a key mechanism in plants that helps other processes and maintains water and nutrient balance.

The rate of transpiration is inversely related to the humidity of the atmosphere.

Stomata only open when there is light. As a result, transpiration is greatest during the day and lowest at night.

When soil moisture is less, roots absorb less water from the earth. As a result, the stomata close and the plant wilts. As a result, the rate of transpiration is reduced.

Therefore, humidity is the factor which affects transpiration negatively. The correct answer is option 1.

In four neurotransmitter molecules the catecholamine is bound to each molecule of ATP because the synaptic vesicles and synaptic granules on the neurotransmitter contain adenosine triphosphate with a molar ratio of catecholamine to ATP of approximately 4:1.

Hormones that play a role in the nervous system are catecholamines in the form of epinephrine (adrenaline) and norepinephrine (noradrenaline). The adrenal medulla contains chromaffin granules (organelles in cells) which function for the biosynthesis, absorption, storage, and secretion of catecholamines.

Other compounds contained in these granules are ATPMg2+, Ca2+, Dopamine-β-hydroxylase (DBH), and the protein chromogranin. Catecholamines enter the granules by a transport mechanism with an ATP-dependent ratio of catecholamines : ATP = 4 : 1. Norepinephrine is stored in the granules, can leave and undergo methylation of the N-terminal end of the protein to form norepinephrine and then enter new granules.

The process is called reflex action when your nervous system does you to pull your finger away before you even think about it.

A sudden, reflexive response to stimuli is known as a reflex action. It aids organisms in making a fast adjustment to a bad situation that could otherwise result in physical injury or even death.

A typical reflex action is pulling our hands away right away after touching something that is hot or cold. Your brain receives an immediate signal from your pain receptors telling it to stay away from the painful area.

These acts are performed by motor neurons, which move your hand or activate the heart muscles. The peripheral nervous system is in charge of carrying out these tasks.

Answer: 25%

Explanation: Heterozygous means that an individual has two different versions, or alleles, of a gene. In this case, one plant has an allele for round seeds and an allele for wrinkled seeds, while the other plant also has an allele for round seeds and an allele for wrinkled seeds. When these two plants are crossed, each offspring will inherit one allele for seed shape from each parent.

The probability that an offspring will have wrinkled seeds is determined by the proportion of offspring that inherit the allele for wrinkled seeds from both parents. If both parents are heterozygous, this means that each parent has a 50% chance of passing on their allele for wrinkled seeds to their offspring. Therefore, the probability that an offspring will inherit the allele for wrinkled seeds from both parents is (0.5)(0.5) = 0.25, or 25%. This means that the probability that an offspring will have wrinkled seeds is 25%.
