Come up with a way to remember the difference between B cells and T cells.

Answers

Answer: B cells produce and secrete antibodies, activating the immune system to destroy the pathogens. The main difference between T cells and B cells is that T cells can only recognize viral antigens outside the infected cells whereas B cells can recognize the surface antigens of bacteria and viruses.

Answers

Answer:

óxido ácido y óxido básico

Explanation:

Los óxidos son compuestos químicos formados por la combinación de un elemento químico con el oxígeno (O). Si el elemento que se combina es un metal, el óxido formado se denomina óxido básico. Por el contrario, si el elemento que se combina es un no metal, el óxido resultante es un óxido ácido.

Se (Selenio) es un elemento no metálico, por lo que su óxido (SeO) es un óxido ácido.

Hg (Mercurio) es un elemento metálico, por lo que su óxido (HgO) es un óxido básico.

how would you compare the magnetic field generated by a simple length of wire to a magnetic field generated by a coil length of wire?

Answers

Answer:

The coil generates a stronger magnetic field. The coil generates a weaker magnetic field. The field generated by the coil has a different polarity than the field generated by the length of wire.

Explanation: Good Luck!!

Answer:

The amount of magnetic field generated by the wire can be calculated if you know the length of wire and current. ... You can add more coils on top of the first row, and this just adds more field strength. In technical terms, every coil of wire increases the "magnetic flux density" (strength) of your magnet.

The coil generates a stronger magnetic field. The coil generates a weaker magnetic field. The field generated by the coil has a different polarity than the field generated by the length of wire.

Explain why finding the average energy of the system would be a smarter way to record the temperature than giving the energy of each individual particle

Answers

Answer:

See Explanation

Explanation:

Temperature is defined as the average kinetic energy of the particles of a system.

In a system, there are several particles moving at various velocities and having various values of kinetic energy. It is very difficult to determine the individual kinetic energies of each individual particle.

Hence, we only need to obtain the average kinetic energy of the particles of the system in order to record the temperature.

Thinking about the process of meiosis, how do you think it is possible for gametes to end up with too many or too few chromosomes?

Answers

But an egg or sperm only has one. That one is chosen at random, through a process called meiosis. When meiosis messes up, you can end up with to many or too few chromosomes. One extra chromosome in a egg or sperm means three in the fertilized egg and so trisomy.

Through the process of meiosis, it is possible for gametes to end up with too many or too few if they fail to separate properly.

What is Meiosis?

Meiosis is defined as the specialized type of cell division of germ cells in sexually-reproducing organisms that produces gametes such as sperm or egg cells. This involves two rounds of division which eventually result in four cells with only one copy of each chromosome.

This is called reduction division because the number of chromosomes in the daughter cells becomes half that of the parent cell. For example, a human cell has 46 chromosomes, but the egg and sperm cells produced as a result of meiosis have 23 chromosomes.

If chromosomes split unequally, an egg or sperm may end up with too many or too few chromosomes; when one of these participates in fertilization, the embryo may end up with too many or too few chromosomes.

Thus, through the process of meiosis, it is possible for gametes to end up with too many or too few if they fail to separate properly.

Toxic substances are also classified by how people are exposed to them. By definition, people may be exposed intentionally, accidentally, or deliberately.
True or False

Answers

Answer:

The statement is true.

Explanation:

When a chemical substance is dangerous for people's health, we speak of a toxic risk. This risk can materialize if exposure to the chemical agent is not controlled. Toxic substances are those substances capable of causing harmful effects in a living organism when they come into contact with it or when ingested,  intentionally, accidentally, or deliberately. The toxic risk of a chemical product depends on two factors: the toxicity and the absorbed dose, where a series of factors influence: composition, properties, concentration, duration of exposure, route of entry into the organism and workload.

What part of Henry's cochlea may have functional hair cells?

Answers

The inner role is the actual receptor that consist of up to 95% fibers of the auditory nerve. These cells are found in an organ of Corti in the inner region of the ear. The hair cells are responsible for the responsive mechanism of the ear. They respond to various sounds, that is, mechanical stimulation.

The organ of Corti of Henry's cochlea may have functional hair cells, it is the structure that makes the hearing organs.

What is cochlea?

Sound waves enter the ear from the outside environment and pass through the external auditory canal before they hit the eardrum and cause it to vibrate.

The incus collects sound vibrations from the malleus, also known as the "hammer," which connects to the eardrum, and sends them on to the stapes.

The stapes are a network that moves the oval window in and out. This motion is collected by the cochlea, a fluid-filled snail-like structure that houses the organ of Corti, the hearing organ, and small hair cells that make up the lining of the cochlea.

Therefore, the organ of the Corti part of Henry's cochlea may have functional hair cells.

What is the difference between a guard cell and a white blood cell?​

Answers

Guard cells exist in plants while white blood cells exist in animals’ body.
Blood cells can guard body btw.

Guard cells are found in plants and white blood cells are found in animals.

What are guard cells?Guard cells are specialised plant cells that regulate gas exchange in the epidermis of leaves, stems, and other organs. They are created in pairs, with a stomatal orifice separating them.

What are white blood cells?The immune system's white blood cells, also known as leukocytes or leucocytes, are responsible for defending the body against both infectious diseases and foreign invaders. All white blood cells are created and developed from hematopoietic stem cells, which are multipotent cells found in the bone marrow. All parts of the body, including the blood and lymphatic system, include leukocytes.

Guard cells function to allow gaseous exchange and white blood cells are responsible for the functioning of the immune system.

Answer: C. To prevent self-fertilization of the pea plants.

Mendel removed the stamens of some pea plants during his first experiment to prevent self-fertilization of the pea plants (Option C).

Who was Mendel?

Mendel was a Hungarian botanist who is considered the father of genetics as a discipline.

Mendel's experiments consisted of crossing pea plants, which exhibit auto fertilization.

Mendel observed how phenotypic characters are inherited by crossing different pea plants.

In conclusion, Mendel removed the stamens of some pea plants during his first experiment to prevent self-fertilization of the pea plants (Option C).

Plants take energy
from the sun
and make food, which for plants is

Answers

Answer:

Photosynthesis

Explanation:

Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Answer:

[tex]\boxed {\boxed {\sf Glucose}}[/tex]

Explanation:

Plants (plus some bacteria and algae) are autotrophs and undergo a process called photosynthesis.

They obtain light energy from the sun and capture it using a green pigment called chlorophyll, water from the soil is drawn up through the roots with capillary action, and carbon dioxide diffuses into stoma on leaves.

Then, in the chloroplast, these substances are turned into oxygen and glucose. Both of these are used in cellular respiration, which creates energy for the plant to grow and carry out cellular and biological functions. Therefore, glucose is often called "food" for the plant.
