Image result for Explain how cells are related to living things.

Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function. Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions.

Explanation:

Unlike flukes and tapeworms, which are parasitic and must locate and attach to a host in order to survive, planarians are free-living, non-parasitic flatworms.

The parasitic flatworms adhere to their hosts using  and hooks. A scolex is the term for the tapeworm's ring-shaped hooks.

The initial symptoms of an infection are frequently itching and a localised rash. As the larvae pierce the skin, these symptoms appear.

A person with a minor illness could not exhibit any symptoms.

Abdominal discomfort, diarrhoea, appetite loss, weight loss, exhaustion, and anaemia may be experienced by someone who has a severe infection.

The equation of the reaction of photosynthesis is:

Light energy + chloroplast + water+ carbon dioxide ---> chemical energy (ATP) + glucose + oxygen

Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.

Light energy is gathered and utilized during photosynthesis in green plants to transform water, carbon dioxide, and minerals.

The equation of the reaction of photosynthesis can be written below as follows:

Answer:

Intrauterine insemination IU

Explanation:

In  this scenario the required numbers of sperm are not released in the semen of the Hans needed to fertilize Sharon ovum..Therefore,a technique is needed to directly inject  an healthy sperm, into her uterus to fertilised  her ovum directly,the technique is IU.

It is a process which involve the selection of healthy sperm.and injected this during ovulation in the female.With this procedure,the likelihood of fertilization  and pregnancy occurring is high,as the distance,time  and competition with other sperm cells is reduced.This makes the procedure reliable.

It is simple technique which involves the sperm washing to get the best concentration of sperm to use, monitoring of the ovulation and  optimal timing; which targets best time of ovulation,usually day 1 or day 2 after ovulation.

it is relatively less expensive.

Answer:

C

Explanation:

Fertilizers and pesticides can pollute groundwater even far away from lakes and oceans. This is incorrect about Jason's statement. Therefore, option C is correct.

The discharge of pollutants into water bodies that render the water unfit for human use and disturb aquatic ecosystems is referred to as water pollution. Several diverse contaminants, such as petroleum, toxic waste, and disease-causing bacteria, can lead to water pollution.

The ecology might suffer greatly as a result of water pollution. Moreover, harmful substances can enter our bodies through the food chain and cause disease and even death.

Thus, fertilizers and pesticides can pollute groundwater even far away from lakes and oceans. This is incorrect about Jason's statement. Therefore, option C is correct.

The mutation that occurred in the mouse is a silent mutation since it does not affect the amino acid sequence in the protein.

A mutation is a change that occurs in the sequence of nucleotides in the DNA of organisms.

A mutation can either have deleterious effect on the organism or have no effect at all. Mutations that do not have any effect on the organism are known as silent mutations.

Silent mutations do not affect the sequence of amino acids that make up a protein.

Therefore, the mutation that occurred in the mouse is a silent mutation since it does not affect the amino acid sequence in the protein.

Answer:

Question 13:

B. False

The most abundant photoreceptors that detect dim light are Rods, not Cones. Rods are highly sensitive to low light conditions and are responsible for vision in dim light and peripheral vision. Cones, on the other hand, are responsible for color vision and high visual acuity but are less sensitive to low light conditions.

Question 14:

A. True

The iris is the muscular tissue in the eye that adjusts the size of the pupil, controlling the amount of light entering the eye. It contracts or expands to regulate the size of the pupil in response to changing light conditions.

Question 15:

B. False

Opsins are visual pigments found in photoreceptor cells, specifically in the retina of the eye. They are responsible for capturing light and initiating the process of vision. Opsins are not derived from Vitamin D. Vitamin D is a separate compound involved in various physiological processes in the body, including calcium absorption and bone health.

When comparing bacterial and eukaryotic genomes, the bacterial genome is generally smaller and, therefore, contains less DNA and fewer genes.

Bacterial genomes are typically circular and lack the complex organization and compartmentalization found in eukaryotic genomes. Bacterial genomes encode the essential genetic information required for the organism's survival and reproduction, including genes involved in DNA replication, transcription, translation, and metabolism.

However, they lack many of the non-essential genes found in eukaryotic genomes, such as those involved in development, cell signaling, and immune function. As a result, bacterial genomes are more compact and streamlined, allowing for rapid adaptation to changing environments and efficient use of resources.

Answer:

Due to the deposition of silt.

Explanation:

The Floodplain is a generally flat area of land next to a river or stream. When the river floods, water containing sediments and particles from the upper course and middle course of the river gets washed onto the Floodplain. The nutrients front these sediments and the water is absorbed into the soil for it's enrichment and fertilisation.

Plants have evolved various mechanisms to prevent self-fertilization and to promote outcrossing, which can increase genetic diversity and increase the fitness of the offspring. One mechanism is the prevention of germination of genetically similar pollen.

Plants' ability to avoid self-fertilization has been linked to the pollen coat's S-protein content. These proteins adhere to the female stigma, where the plant's self-incompatibility mechanism detects them. The self-incompatibility system will block pollen germination if it determines that the pollen and the female plant are too genetically similar.

However, the plant's self-incompatibility system might not be able to identify a pollen spore as being too genetically similar if it is unable to contain S-proteins in its pollen coat. In this situation, it's possible that the pollen will grow, fertilize the ovules, and cause self-fertilization.
