Explanation:

he was able to find chromosomes in plants

Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the conclusion that genes are inherited as distinct, paired units from each parent.

What is Non-Mendelian Inheritance?

Inheritance of features with a more complicated genetic base than one gene with two alleles and total dominance is referred to as non-Mendelian inheritance.

One allele may not always be dominant over another, resulting in a phenotype that falls between the two parents in certain people.

Incomplete dominance is the name given to this inheritance pattern. Snapdragon flowers, for instance, exhibit partial dominance.

When both alleles are present at the same time, this pattern of inheritance is referred to as partial dominance, since neither allele is totally dominant over the other.

Therefore, red and white snapdragons cross to produce exclusively pink progeny.

Two species are capable of mating and producing fertile offspring, because they have no choice, so they would have to produce leading in speciation.

Consistent with the organic species idea, organisms belong to the equal species if they are able to interbreed to provide viable, fertile offspring. Species are separated from one another by way of prezygotic and postzygotic limitations, which prevent mating or the production of possible, fertile offspring.

Organisms from two exceptional species mix, or breed collectively, miles known as hybridization. The offspring which are comprised of those mixes are known as hybrids. Hybrids arise within the natural global and are a powerful evolutionary force.

The answer is C) Return a small portion of the mined material to the earth.

Reclamation is the process of restoring land that has been mined or disturbed back to its natural state or a useful purpose. The steps in the reclamation process include removing equipment and buildings, stabilizing the soil, restoring the topography, replanting native plants, and filling in holes. Monitoring the area for years after the mine is closed is also essential to ensure that the reclamation is successful. However, returning a small portion of the mined material to the earth is not a step in the reclamation process.

Therefore, the correct answer is C) Return a small portion of the mined material to the earth.

Based on the classification system, we can say that plants and animals are more alike than plants and bacteria. This is because plants and animals belong to the same kingdom, the Kingdom Plantae and Kingdom Animalia respectively, whereas bacteria belong to a separate kingdom, the Kingdom Monera.

Plants and animals share similar characteristics such as multicellularity, the presence of organelles, and the ability to produce and store energy. They also have a similar mode of reproduction, through sexual or asexual means. On the other hand, bacteria are single-celled organisms that lack a nucleus and other organelles, and their mode of reproduction is asexual.

Although plants and bacteria share certain characteristics such as the ability to produce their own food through photosynthesis, the differences between them are more significant than their similarities.

Asthmatics tend to have their airways narrowed by smooth muscle constriction, thickening of the walls, and mucus secretion. This condition can affect vital capacity, FEV1, and MVV. Let's discuss how these factors are affected.

Vital capacity: Vital capacity is the maximum amount of air that a person can breathe out after taking the deepest breath possible. Vital capacity decreases in asthma due to bronchoconstriction, which narrows the airways and makes it more difficult for air to enter and exit the lungs.FEV1: FEV1 (forced expiratory volume in one second) is the amount of air that a person can forcefully exhale in one second.

FEV1 is reduced in asthma due to bronchoconstriction, which reduces the amount of air that can be exhaled in one second. MVV: Maximum voluntary ventilation (MVV) is the maximum amount of air that a person can breathe in and out in one minute. It's a measure of lung function. Asthma can reduce the MVV due to bronchoconstriction, which can make it difficult to breathe in and out at a normal rate. Bronchoconstriction, mucus secretion, and thickening of the airway walls can reduce the efficiency of gas exchange, reduce lung capacity, and make it more difficult to breathe.

Answer:

The organism is physically stronger than competing organisms.

Explanation:

DNA replication is the process through which DNA duplicates. It occurs in the interphase and involves different enzymes, DNA molecules, and free nucleotides. Terms and definitions in the attached files.

DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.

DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.

The origin of the replication requires helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated. Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter into the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs timine, and cytosine pairs guanine.

DNA strands are antiparallel, and replication occurs only in 5'-3' direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.

Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.

The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.

Thus, It happens in a variety of media, including gases, liquids, and solids. The inherent propensity of particles to travel down their concentration gradient in search of equilibrium is the driving force underlying diffusion.

On the other hand, osmosis is a particular kind of diffusion that entails the passage of water molecules over a membrane that is only permeable in certain places. It happens when the solute concentrations on opposite side of the membrane differ.

Thus, The movement of particles (such molecules or ions) from a region of higher concentration to a region of lower concentration is known as diffusion.

The process that is opposite to photosynthesis is cellular respiration. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose (sugar) and oxygen. During photosynthesis, carbon dioxide and water are used as raw materials, and the process produces oxygen and glucose.

In contrast, cellular respiration is the process by which organisms, including plants and animals, break down glucose and other organic molecules to release the energy stored within them. During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate). The released energy is used by the cell to carry out various metabolic activities. So while photosynthesis produces oxygen and glucose and uses carbon dioxide, water, and light energy, cellular respiration uses oxygen and glucose to produce carbon dioxide, water, and energy. The two processes are interdependent and together form the basis of the carbon cycle and energy flow in the biosphere.
