1) Reflection is when a ray hits something reflective then bounces back. For example, light reflects off a mirror, which is why you can see yourself in a mirror.

2) Wavelength measures the size of a wave. It is measured from the crest or trough of one wave to the crest or trough of another.

3) Refraction occurs when waves go through different mediums at different speeds. This is why a straw looks bent when in water.

4) Frequency is a way of measuring the speed of a wave. It shows how many waves pass every unit of time.

5) Absorption means that all of the waves were absorbed into the medium and none of them passed through.

Explanation:

Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar

If the system noise temperature is reduced, then the SNR increases. The amount of increase depends on the reduction in the noise temperature.  Therefore, the SNR increases.

The signal-to-noise ratio (SNR) is a measure of the signal strength to noise power ratio. It represents the ratio of the power of a signal compared to the power of background noise.

When it comes to how the SNR changes in different scenarios, we can answer the following:

If the range is decreased by a factor of 10, then the SNR decreases by 20 dB.

This is because the power of the signal decreases with the square of the range, whereas the noise remains constant. So, decreasing the range by a factor of 10 decreases the power of the signal by 100 times, or 20 dB.

If the transmit power is doubled, then the SNR increases by 3 dB.

This is because the power of the signal increases by 2 times, whereas the noise remains constant. So, doubling the transmit power increases the power of the signal by 2 times, or 3 dB.If the receive antenna diameter is halved, then the SNR decreases by 6 dB.

This is because the gain of an antenna is proportional to the area of the antenna, so halving the diameter reduces the gain by a factor of 4, or 6 dB.

If the system noise temperature is reduced, then the SNR increases. The amount of increase depends on the reduction in the noise temperature.

For example, if the noise temperature is reduced by 10 times, then the SNR increases by 10 dB.

This is because the noise power is proportional to the noise temperature, so reducing the noise temperature reduces the noise power. Therefore, the SNR increases.

If enough water pressure builds under the surface of the ground, the water can burst through cracks in the surface, forming an is geyser. Hence the correct option is C.

A geyser is a natural hydrothermal feature characterized by intermittent eruptions of hot water and steam. It occurs when groundwater becomes heated by geothermal energy and builds up pressure underground. The pressure eventually becomes strong enough to cause the water to burst through fractures or channels in the Earth's surface, resulting in the explosive release of water and steam into the air.

Geysers are typically found in geologically active regions with volcanic activity or hot springs. The pressure buildup occurs due to the combination of heat and the confinement of water within the subsurface. As the water reaches its boiling point and turns into steam, the expanding steam forces the water above it to erupt explosively, creating the characteristic geyser eruption.

Hence the correct option is C.

Autonomic fibers are nerve fibers that make up the autonomic nervous system (ANS), which controls the involuntary actions of organs and tissues throughout the body. These fibers are classified into two types: long autonomic fibers and short autonomic fibers.

Long autonomic fibers originate from the thoracic and lumbar regions of the spinal cord and synapse with ganglia located closer to the target organs. This is known as the sympathetic division of the ANS. An example of long autonomic fibers is the preganglionic neuron that releases acetylcholine and synapses with postganglionic neurons in the adrenal medulla. The adrenal medulla then releases epinephrine and norepinephrine, which affect a variety of organs and tissues, including the heart, lungs, liver, and adipose tissue.

The flow chart can be represented as follows:

Exocytosis of vesicles that contain CRH --> Anterior pituitary gland releases ACTH --> ACTH enters the bloodstream and binds with receptors present over the adrenal gland --> Adrenal cortex releases cortisol into the bloodstream, increasing blood pressure, blood glucose levels, etc. --> Promotes synthesis of cortisol

Exocytosis of vesicles that contain CRH: The release of cortisol begins with the secretion of corticotropin-releasing hormone (CRH) from the hypothalamus. CRH is stored in vesicles and is released by exocytosis into the bloodstream.

Anterior pituitary gland releases ACTH: CRH stimulates the anterior pituitary gland to release adrenocorticotropic hormone (ACTH). ACTH is released into the bloodstream.

ACTH enters the bloodstream and binds with receptors present over the adrenal gland: ACTH travels through the bloodstream and reaches the adrenal glands.

Adrenal cortex releases cortisol into the bloodstream, increasing blood pressure, blood glucose levels, etc: When ACTH binds to the receptors on the adrenal cortex, it stimulates the release of cortisol.

Promotes synthesis of cortisol: Cortisol synthesis is stimulated by ACTH. When ACTH binds to the receptors on the adrenal cortex, it initiates a series of biochemical reactions that promote the synthesis and release of cortisol.

This flow chart outlines the sequential steps that lead to an increase in plasma cortisol levels, starting from the release of CRH from the hypothalamus to the synthesis and release of cortisol from the adrenal glands.

The nonselective passive process performed by the glomeruli that forms blood plasma without blood proteins is called ultrafiltration.

In the process of ultrafiltration, blood flows through the glomerular capillaries, which are surrounded by a network of specialized cells known as podocytes. The podocytes form small openings called filtration slits, which allow water and small solutes to pass through while blocking the passage of larger molecules like blood proteins.

As a result, a filtrate is formed that contains water, ions, glucose, amino acids, urea, and other small solutes that are normally present in blood plasma, but it lacks larger proteins like albumin and globulin. This filtrate is then further processed by the renal tubules to produce urine, which is eventually eliminated from the body.

Ultrafiltration is an important process in the kidney that helps to regulate the composition of blood and maintain the balance of fluids and solutes in the body. It is one of the first steps in the formation of urine and is essential for maintaining proper kidney function.

During DNA replication in E. coli, the cell prevents the DNA strands from reannealing and seeking maximum stability through the action of single-stranded binding proteins (SSBs) and DNA helicase.

DNA replication in E. coli requires the separation of the DNA double helix to expose the template strands for replication. However, the DNA strands have a natural tendency to reanneal and seek maximum stability, which would hinder the replication process. To prevent this, the cell employs several mechanisms.

Firstly, single-stranded binding proteins (SSBs) play a crucial role in preventing reannealing. SSBs bind to the single-stranded DNA regions exposed during replication and stabilize them. By binding tightly to the single-stranded DNA, SSBs prevent the strands from forming hydrogen bonds with complementary sequences and reannealing.

Secondly, DNA helicase is another key player in preventing reannealing. Helicase is an enzyme that unwinds the DNA double helix by breaking hydrogen bonds between the base pairs. As the helicase moves along the DNA molecule, it continuously separates the strands, preventing them from reannealing.

Together, SSBs and DNA helicase work synergistically to maintain the separation of the DNA strands during replication. The SSBs stabilize the single-stranded DNA regions, while the helicase unwinds the double helix, ensuring that the replication machinery can access the template strands and synthesize new DNA strands without interference from reannealing. This coordination is essential for accurate and efficient DNA replication in E. coli.

Protozoa are classified as Protista. The correct option is C.

Protozoa are single-celled eukaryotes that are neither plants nor animals. They are a diverse group of organisms that can be found in all types of environments, including water, soil, and air.

Protozoa are heterotrophic, meaning that they get their energy from consuming other organisms. They can be free-living or parasitic. Some protozoa are important in the food chain, while others can cause disease in humans and animals.

The kingdom Protista is a catch-all category for eukaryotes that do not fit neatly into other kingdoms. It includes protozoa, algae, fungi, and slime molds. Protozoa are classified into different groups based on their mode of locomotion, feeding habits, and other characteristics. Some common groups of protozoa include:

Flagellates: Protozoa that move using flagella, which are long, whip-like structures.

Ciliates: Protozoa that move using cilia, which are short, hair-like structures.

Amoebas: Protozoa that move by extending pseudopodia, which are temporary extensions of the cytoplasm.

Sporozoa: Protozoa that are parasitic and do not have any means of locomotion.

Protozoa play an important role in the environment. They are a food source for other organisms and they help to break down organic matter. Protozoa can also be harmful to humans and animals, causing diseases such as malaria, sleeping sickness, and giardiasis.

What is Vitamin D?

Vitamin D is a fat-soluble vitamin that is added to some foods, found naturally in a few, and sold as a dietary supplement. When ultraviolet (UV) rays from sunshine strike the skin and start the synthesis of vitamin D, it is also created endogenously.The body needs to go through two hydroxylations in order to activate vitamin D that is consumed through diet, supplements, and sun exposure. During the first hydroxylation, which takes place in the liver, vitamin D is changed into 25-hydroxyvitamin D, sometimes referred to as "calcidiol." The second hydroxylation, commonly known as "calcitriol," is predominantly carried out in the kidney and results in the physiologically active 1,25-dihydroxyvitamin D.
