Photic zone up to 200 meter depth and includes photosynthetic plants, sea anemones, sponges, crabs, and clams. The correct option is B.

The photic zone, also known as the euphotic zone, epipelagic zone, or sunlight zone, is the uppermost layer of a body of water where phytoplankton can perform photosynthesis.

It goes through a number of physical, chemical, and biological processes that allow nutrients to enter the upper water column.

The photic zone is the top layer of the ocean, closest to the surface, and is also known as the sunlight layer. Enough light penetrates the water in this zone to allow photosynthesis.

Thus, the correct option is B.

O a spore

Hope it helped you buddy brainiest plz and thank you!!!!!

A spore is the cell which is produced on the underside of a fern that can grow into a new fern. These are a mode of asexual reproduction. Thus, the correct option is C.

A fern is a member of a group of vascular plants which reproduces by the formation of spores and neither by seeds nor by flowers. Fern plants belong to the clade Tracheophytes and division Polypodiophyta.

Ferns are the plants which reproduce from spores that are gathered in the form of clusters called sori, which are usually present on the underside of the fronds of fern. The spores can be yellow, green, brown, or black in color. The sori are sometimes covered with a membrane known as the indusium, which lifts up when the spores are ripe and drop off from the plant.

Therefore, the correct option is C.

Oral enclomiphene citrate has been found to stimulate the production of testosterone and increase sperm counts in men with low testosterone levels. This effect has been compared to the use of testosterone gel as a treatment for low testosterone.

Enclomiphene citrate is a selective estrogen receptor modulator (SERM) that is commonly used in the treatment of female infertility. However, research has shown that enclomiphene citrate can also be effective in treating low testosterone levels in men. It works by acting on the hypothalamus and pituitary glands to increase the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn stimulates the production of testosterone in the testes.

In a comparison study with testosterone gel, oral enclomiphene citrate has shown similar efficacy in increasing testosterone levels and improving sperm counts in men with low testosterone. This offers an alternative treatment option for individuals who may prefer an oral medication over a topical gel. However, it is important to note that the use of enclomiphene citrate should be monitored and prescribed by a healthcare professional, as it may have potential side effects and requires careful consideration of individual circumstances and medical history.

Explanation:

Answer:

Numerous types of transportation are available to living things, including:

1. Circulation: The movement of oxygen, nutrients, hormones, and waste materials throughout the body is referred to as circulation. The heart, blood arteries, and blood make up an animal's circulatory system.

2. Respiration: This is the process through which an organism and its surroundings exchange gases like oxygen and carbon dioxide. Animals and plants both use their lungs or gills for respiration, while plants use small openings called stomata.

3. Lymphatic system: This system of tissues and blood arteries aids in the removal of extra fluid from the body and the movement of immune cells to the areas of infection.

4. Transport in plants: Through specialised tubes known as xylem and phloem, water and nutrients are transferred from the roots to the rest of the plant in plants. Translocation is a procedure that is crucial for the development and survival of plants.

The mode of transmission in this scenario is indirect contact, also known as indirect contact transmission.

The mode of transmission that has happened here is indirect contact transmission. Indirect contact transmission occurs when an individual comes into contact with a contaminated surface, and then transfers the infectious agent to themselves through contact with their eyes, nose, or mouth.

In this case, the contaminated surface was the ATM buttons that the infected person touched before you, and you came into contact with them, transferring the virus to your eyes and ultimately into your nasal cavity. This is a common way that influenza and other respiratory viruses are transmitted, and is why it is important to wash your hands regularly and avoid touching your face.

In this population of 500 jackrabbits, the observed genotype frequencies can be calculated based on the given phenotype frequencies.

The phenotype frequency of black rabbits is 0.5, gray rabbits is 0.3, and white rabbits is 0.2. Using the Hardy-Weinberg principle, we can determine the expected genotype frequencies. Assuming that the population is in Hardy-Weinberg equilibrium, the expected genotype frequencies are 0.25 for fbfwfbfw (black), 0.2 for fbfwfwfw (gray), and 0.04 for fwfwfwfw (white).

By dividing the expected genotype frequencies by the sum of all three expected frequencies, which is 0.49, we can calculate the observed genotype frequencies. Thus, the observed genotype frequencies in this population are approximately 51% for fbfwfbfw (black), 41% for fbfwfwfw (gray), and 8% for fwfwfwfw (white).

Explanation:

Answer:

C. Respiration can happen without sunlight, but photosynthesis

cannot.

Explanation:

Respiration is the metabolic process by which the cells of living organisms, plants inclusive, obtain energy. Photosynthesis, on the other hand, is the process whereby plant cells synthesize their food in form of sugars (glucose).

Photosynthesis takes place in two stages namely: light dependent stage and light independent stage. The light dependent stage occurs strictly in the presence of sunlight, where oxygen gas is released as a product. Hence, it can only occurs during the day. Respiration, which breaks down the sugar product of photosynthesis to produce energy, occurs at anytime (day or night). Carbon dioxide (CO2) gas is released as a product.

Since the light dependent stage of photosynthesis cannot occur without sunlight, it cannot occur at night. this means that oxygen gas will not be released at night. However, respiration which occurs during daytime and nighttime continually releases carbon dioxide gas. This accounts for the reason CO2 gas is produced more by plants than oxygen at night.

Answer:

c

Explanation:

Remember, put this into your own words. Your education system will detect you copied/paraphrased from an online source.

Photosynthesis uses certain things to produce sugars, oxygen, etc.

It uses these things: Sunlight, water, carbon dioxide.

Therefore it uses the energy from the sun.

This supports the law of conservation which states energy cannot be created, nor destroyed. It re-uses energy, like the sun's light.

Second class levers have load closer to the fulcrum , so they will always allow a smaller effort to move a larger load, giving a mechanical advantage.

In second class lever the load is in the middle between the fulcrum and effort . this kind of lever is found in ankles area. In a second class lever the effort moves over a large distance to raise the load a small distance. As the ratio of effort (force) arm length to load arm length increases, the mechanical advantage of a second class lever increases.

when the digestive system requires lactase, it manufactures the protein based on information stored in DNA molecule.

The DNA follows up on this information to create a particular sort of protein for the orderly digestion of milk. As a result, when the digestive system needs lactase, it produces the protein using data stored in the DNA molecule. A sort of bodily system known as the digestive system is responsible for breaking down the food and liquids that we intake via our mouths into simpler compounds that the body may use for energy, growth, and tissue repair.

In order to digest milk, a person's body must produce a protein known as lactose. This protein creates the lactase enzyme, which breaks down milk into its glucose and galactose components. These components are easily absorbed and utilised by the body as needed.
