Answer:

I think its vacuoles

Explanation:

The reason for keeping a chloroplast in darkness for some time prior to fixation for electron microscopy is to deplete the starch content within the chloroplast.

Starch is a storage carbohydrate that accumulates in chloroplasts during the light period through photosynthesis.

By keeping the chloroplast in darkness, the plant is not actively performing photosynthesis, and therefore, the starch reserves are gradually depleted.

When preparing samples for electron microscopy, it is important to fix the chloroplasts.

If the chloroplast contains starch, it can be affected during the fixation process, leading to distortions in the final electron micrographs.

Thus, by depleting starch the chloroplast is closer to its natural state, allowing for more accurate observations and analysis under the electron microscope.

The process of evolution that involves a change in the DNA sequence that leads to evolutionary change is called a mutation.

A mutation is a sudden and lasting alteration in the DNA sequence that can influence genetic variation. Changes in the DNA sequence can influence phenotype, which may or may not have an effect on an organism's fitness. Mutations occur spontaneously, either from errors in DNA replication or from exposure to mutagenic agents. Mutations may happen in either coding or non-coding regions of the DNA, and they can be either silent or expressed.

Evolution is a natural process that results in the gradual change of inherited characteristics in populations over generations. It is the process of alteration in the inherited characteristics of species over successive generations. In other words, it is the process of gradual changes that happen to species over time as they adapt to their environments. It can be defined as a change in the gene frequency in a population over time.

Types of Evolution 1. Natural Selection 2. Genetic Drift 3. Gene Flow 4. Mutation 5. Non-Random Mating 6. Admixture 7. Mutation Pressure 8. Genetic Draft 9. Bottleneck and Founder Effect 10.

However, when Psyche has always been helped make immortal, the power of prayer overcomes everything so that the two main characters can indeed be formed forever.

Resource partitioning is a situation where several different species occupying the same ecosystem share resources. In resource partitioning, competition for resources is reduced by using the resources at different times or in different ways.

A good example of resource partitioning is the case of a small rodent species, Peromyscus maniculatus, that arrives on an island with a wide diversity of seed-producing species and high insect diversity. The small rodent can adjust its diet by consuming different food sources, including seeds and insects. For instance, Peromyscus maniculatus can feed on various plant seeds during the day when other insect predators are active.

 Alternatively, the rodent can feed on insects at night when the other animals are sleeping. By doing so, the small rodent avoids direct competition with other seed-eating animals and insect predators. The adaptation of Peromyscus maniculatus to eating different food sources at different times is a good example of how resource partitioning helps reduce competition among different species.

As the cardiac cycle begins, the semilunar valves are closed because the pressure exerted by the blood in the ventricles is higher pressure lower than the pressure the blood exerts int he great arteries.

A series of changes in pressure within the heart occur during the cardiac cycle. Blood flows through the various cardiac chambers and throughout the body as a result of these pressure changes.

Atrial and Ventricular diastole, Atrial systole, and Ventricular systole are the phases during which the heart's chambers rest and fill with blood (ventricles contract and push blood out through aorta and pulmonary artery).

A light year unit is very large and distances in space are very large. So, the correct option is D.

A light year is defined as the larger unit of length which is used to express astronomical distances and is approximately equal to 9.46 trillion kilometers or 5.88 trillion miles.

A light-year is expressed as the distance that light travels in a vacuum in one Julian year, which is 365.25 days because it includes the term "year", the term light-year is sometimes misunderstood as a unit of time.

1 light-year   = 9460730472580800 metres

Light year is used as a unit to express distances to celestial objects, for example, if a star is 4 ly away from earth, it means that light from the star will take 4 earth years to reach us.

Therefore, a light year unit is very large and distances in space are very large. So, the correct option is D.

Mechanoreceptors are sensory receptors responsible for sensing distortion in body tissues and are located in muscles, tendons, ligaments, and joint capsules of the human body.

Mechanoreceptors detect changes in mechanical pressure or tension, such as stretching, compression, or vibration. They play a crucial role in proprioception, which is the awareness of the body's position and movement in space. This awareness allows us to maintain balance, coordinate movements, and respond to external stimuli.

There are various types of mechanoreceptors, including muscle spindles, Golgi tendon organs, Ruffini endings, and Pacinian corpuscles. Each of these receptors has unique properties and functions that contribute to our overall sensory experience and enable us to perform complex motor tasks.

The hereditary deafness in dogs caused by the recessive gene "d" is inherited in a simple Mendelian fashion. The gene has two alleles: "d" for the deafness allele and "D" for the normal hearing allele.

The "d" allele is recessive, which means that an individual must have two copies of the "d" allele in order for the deafness to be expressed. An individual with one copy of the "d" allele and one copy of the "D" allele is known as a carrier of the deafness gene and will not be deaf.

Given that Gilbert is a male dog and can hear, we know that he does not have two copies of the "d" allele and therefore must have at least one "D" allele. There are two possible genotypes (genetic makeup) for Gilbert:

DD - this genotype means that Gilbert has two normal hearing alleles, and will not be deaf, and also will not pass the deafness gene to his offspring.

Dd - this genotype means that Gilbert has one normal hearing allele and one deafness allele, meaning he is a carrier of the deafness gene but not affected by it, He will not be deaf but can pass the deafness allele to his offspring.

It's worth noting that it's impossible for Gilbert to have the genotype dd as he is able to hear.
