During the Mesozoic, gymnosperms and dinosaurs coexisted as the dominant species.

"The Age of Reptiles" was the Mesozoic Era, which lasted from 251.9 to 66 million years ago. The present Rocky Mountains rose as Pangaea started to split into the continents we know today. The dominant land and air animals were pterosaurs, crocodiles, and dinosaurs.

The Mesozoic era, sometimes known as the "Middle Life," saw a fast diversification of life on Earth, including the appearance of dinosaurs, enormous reptiles, and other terrifying creatures. The time range, which roughly corresponds to 252 million years ago to 66 million years ago, is sometimes referred to as the age of reptiles or the era of dinosaurs.

When a part of a whole population is not able to breed and give rise to fertile offspring with the remaining population, then a gametic isolation is present which checks the sharing of genes among the two populations.

A gametic isolation is a kind of a pre-zygotic barrier. Such type of a reproductive isolating mechanism ensures that fertilization does not occur following speciation. This biological mechanism prevents the sharing of genes among two populations when a part of a whole population is unable to breed successfully with the remaining population. The formation of a zygote is inhibited in a pre-zygotic barrier.

The process of introducing a dead pathogen or nontoxic part of a pathogen into the body to provoke an immune response that prevents a certain disease is called Vaccination .

Vaccination is the process of administering a vaccine to aid the immune system in developing immunity to a disease. Vaccines contain a weakened, live, or killed microorganism or virus, as well as proteins or toxins from the organism.

Vaccination is a simple, secure, and effective way to safeguard yourself against potentially fatal diseases before being exposed to them. It strengthens your immune system by utilizing your body's own natural defenses to build resistance to specific infections.

Vaccines assist your body to produce protective antibodies, which are proteins that help your body fight infections. By getting vaccinated, you can protect yourself while also preventing the spread of preventable diseases to others in your community.

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%.

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.

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%.

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.

Answer:

Genetic variation is necessary for evolution by natural selection because it (A) results in different traits which can be selected for or against.

Explanation:

Natural selection is a process in which organisms with certain traits are more likely to survive and reproduce, while those with less advantageous traits are less likely to survive and reproduce. This results in the survival of the fittest and the evolution of new species over time. Without genetic variation, there would be no differences in traits and therefore no way for natural selection to occur.
