Answer:
B. Interneurons
Explanation:
The basic unit of the central nervous system is the neuron or the nerve cells. Billions of neurons allow the different parts of the body to communicate with each other via the brain and the spinal cord. A fatty material called myelin coats nerve cells to insulate them and to allow nerves to communicate quickly.

The non-poisonous ____ butterfly gains protection by looking like the bad-tasting ____ butterfly, which is a protective device known as ____.
The non-poisonous viceroy butterfly gains protection by looking like the bad tasting monarch butterfly, which is a protective device known as Mimicry.
Mimicry is a biological phenomenon that occurs by superficial resemblance of two or more organisms that are not closely related taxonomically. The resemblance gives an advantage such as protection from predation upon one or both organisms by which the organism deceive the animate agents of natural selection.The predator interacts with the similar organisms and gets deceived by their similarity.
The discovery of Mimicry in butterflies was in the mid 19th century by Victorian naturalist H.W.Bates. Mimicry in butterflies are of two types- Batesian mimicry and Mullerian mimicry.
The Batesian mimicry is when a non-poisonous animal mimics the pattern or coloration of a poisonous or unpalatable animal without actually producing any toxins themselves.
The Mullerian mimicry is when two poisonous or unpalatable animals have the same coloration and patterns.

What are qualified medical expenses?
The same categories of services and goods that would normally be deductible as medical costs on your yearly income tax return make up qualified medical expenses. Medicare also covers certain Qualified Medical Expenses, such as doctor visits, lab tests, and hospital stays.
Qualified Medical expenses include all costs required for the diagnosis, mitigation, or treatment of disease or injury. Medical expenses include things like health and dental insurance premiums, doctor and hospital visits, co-pays, prescription and over-the-counter medications, glasses and contacts, crutches, and wheelchairs, to name a few.
Taxpayers may use the Section 80DDB deduction for the cost of treating themselves or dependents for a few specific ailments. Section 80DDB allows residents of India who are individuals or HUFs to deduct certain expenses. Only those with specified ailments or their dependents are eligible to claim this deduction.

Many organisms, such as honeybees and livestock, have been domesticated for economic reasons. Which of the following best describes an unintended consequence of this practice
Domestication of many organisms, such as honeybees and livestock causes a decrease in the genetic diversity of the organisms.
Genetic diversity refers to the range of genetically different individuals that are present in the same species. Domestication is the process by which the wild animals as well as plants are adapted to the human environment.
Domestication of livestock and honeybees is often done for economic reasons. An unintended consequence of the process of domestication is the decrease in the genetic diversity of the species. This decreases leads to a decrease in the variation which reduces the survival advantage of these species.

What are the hereditary diseases?
Sickle cell anemia, cystic fibrosis, and hemophilia are some of the hereditary diseases that occur because of changes in the genetic make of an organism.
Hereditary diseases usually referred to as inherited diseases or genetic disorders, are a group of genetic diseases that are brought on by changes in a person's genetic makeup (DNA). These changes are caused by mutation. This occurs when the normal bases in the DNA is replaced with the faulty base or mismatched base.
Then, these illnesses are passed down from one generation to the next, or in other words, they are inherited from one set of parents to another. For example, sickle cell anemia, cystic fibrosis, and hemophilia are some examples of hereditary diseases.
Because sickle hemoglobin requires two copies of the gene to be present, sickle cell anemia is referred to as a recessive condition. They must get one from each parent, which code for abnormal hemoglobin.

What causes different illnesses and even premature death?
Smoking cigarettes and being exposed to secondhand tobacco smoke are leading causes of premature death.
death that occurs earlier than the typical death age for a population. The average death age is around 75 years old. The biggest causes of early death in the US are smoking cigarettes and being around people who smoke. They can make people more vulnerable to developing cancer, heart disease, stroke, lung disease, and a host of other illnesses. Injuries are another reason for early mortality.
Ischemic heart disease, which accounts for 16% of all fatalities worldwide, is the world's leading cause of mortality. This disease has shown the highest increase in deaths since 2000, with an increase of more than 2 million deaths to 8.9 million deaths in 2019. The second and third most common killers, stroke and chronic obstructive pulmonary disease, respectively account for 11% and 6% of all fatalities.
Lower respiratory infections remained to be the most fatal communicable disease worldwide, ranking as the fourth most common cause of death. However, there have been fewer fatalities; in 2019, it claimed 2.6 million lives, 460 000 fewer than it did in 2000.

Does stomach lining, liver, skin repair itself the fastest
The stomach lining is able to heal itself the fastest, followed by the skin, and then the liver.
What do you mean by the stomach lining?
The stomach lining is the innermost layer of the stomach, made up of cells that produce digestive enzymes and secretions that help break down food. This layer also helps protect the stomach from the acidic environment within the stomach.
The stomach lining is able to heal itself quickly because it contains specialized cells that can quickly make new tissue to replace damaged cells. The skin is also able to heal quickly because it is made up of many layers of cells that can quickly reproduce to form new skin. The liver is able to regenerate itself, but it takes longer than the stomach lining or skin because the liver is made up of fewer cells and the process of regeneration is more complex.

2nd question : homogenous and Dominate
3rd question: heterozygous
4th question : homogenous and Recessive
Explanation:
Explain how the result show that both light and chlorophyll must be present for photosynthesis.
Chlorophyll absorbs energy from blue and red light waves during photosynthesis while reflecting green light waves, giving the appearance of a green plant.
Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue. Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Despite the fact that there are numerous steps involved in photosynthesis, there are primarily two stages: light-dependent reactions and light-independent reactions. The light-dependent reaction, as its name implies, occurs inside the thylakoid membrane and necessitates a constant supply of sunshine. The light waves' energy is captured by the chlorophyll and transformed into chemical energy in the form of the molecules ATP and NADPH.
The Calvin Cycle's light-independent stage, which takes place in the stroma, or region between the chloroplast and thylakoid membranes, does not require light, hence the name light-independent reaction. In this phase, carbon dioxide is converted into carbohydrates like glucose using energy from the ATP and NADPH molecules. However, not all types of photosynthesis are made equal. C3 photosynthesis and C4 photosynthesis are two of the various forms of photosynthesis. The majority of plants engage in C3 photosynthesis. It entails the Calvin Cycle producing 3-phosphoglyceric acid, a three-carbon molecule that later transforms into glucose.

A cell cycle, also known as a cell-division cycle is defined as a series of events which take place in a cell as it is growing and dividing in order to form two daughter cells. A cell cycle has a few different stages namely prophase, metaphase, anaphase and telophase.
