Special chemicals that recognize and attach to germs are called what?

A. Antibodies

B. Red blood cells

C. Pathogens

Answers

Special chemicals that recognize and attach to germs are called Antibodies. Thus, the correct option is A.

What is Antibody?

An antibody may be characterized as a protein produced by plasma cells in response to a specific antigen.

The major function of an antibody is to eliminate disease-causing organisms which are known as pathogens or any other external germs and barricade them from contaminating human cells.

Such antibodies after synthesis attach to germs or digested antigenic particles and then mediated the process of eliminating all such foreign particles.

Therefore, special chemicals that recognize and attach to germs are called Antibodies. Thus, the correct option is A.

DNA evidence analysis is an imperfect science. Provide two reasons why this may be the case.

For my Biomedical Science Class

Answers

Answer:

Not all DNA that was found at the scene has to be related to the scene.

Explanation:

Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.

Answer:

Because DNA is more reliable than other forensics, scientists have shrugged off suggestions that it could fall victim to the vagaries of bias. But Dror noted that much DNA analysis involves interpretation. With interpretation comes subjectivity, and with subjectivity can come error. Only one-tenth of 1 percent of human DNA differs from one individual to the next and, although estimates vary, studies suggest that forensic DNA analysis is roughly 95 percent accurate.

Man has a haploid life cycle.

True
False

Answers

Man does not have a haploid life cycle. Haploid life cycle is observed in most of the single-celled organisms. Thus, the given statement is false.

What is haploid life cycle?

The haploid life cycle is the simplest type of life cycle. It is found in most of the single-celled eukaryotic organisms. Organisms with a haploid life cycle spend the majority of their lives in haploid forms as haploid gametes. When these haploid gametes fuse, they form a diploid zygote.

The life cycle of Man is an example of diploid life cycle. The human life cycle involves a mature human cell (2n), eggs are produced by meiosis in the ovary of a woman, and sperms are produced by meiosis in the testis of a man. The eggs and sperm combine in fertilization to form a diploid zygote (2n).

Photosynthesis and cellular respiration differ in which of the following
ways?
O The main source of chemical energy in cellular respiration is water.
The energy conversion in cellular respiration takes place in the chloroplast.
O The main source of energy in cellular respiration is glucose.
The final product of cellular respiration is electromagnetic radiation.

Answers

Answer:

the main source of energy in cellular respiration is glucose.

Explanation:

photosynthesis creates glucose out of co2 h2o and sunlight. while cellular respiration is almost exactly the opposite.

The ways in which photosynthesis and cellular respiration differ is that the main source of energy in the case of cellular respiration is glucose. Hence, Option C is the correct answer.

The photosynthesis and cellular respiration processes are interlinked with a significant relationship. The products of one process act as reactants in the other. Some of the significant differences between both processes are mentioned as follows:

Photosynthesis takes place only in phototrophs such as plants and algae while cellular respiration can take place in all the living forms. Photosynthesis completely takes place in chloroplasts and cellular respiration in Mitochondria. Glucose is made by the process of photosynthesis while glucose is utilized in cellular respiration to make molecules of ATP.

Thus, we can conclude that photosynthesis and cellular respiration differ specifically by the main source of energy. Hence, option C is the correct answer.

Shoot system are defines as the upper part of the plant which means it is the part that lies above the ground or surface. It consists of stem, leaves and flowers. It is responsible for food production and is the production center of a plant.

The root system is the part that is under the soil. It holds the plant in its place and helps to absorb water and mineral from the soil. It helps to store the products of the photosynthesis process from the shoot system.

HOW DOES THE MEIOSIS PROCESS WORK ?

What is different between meiosis and mitosis?

Whats the different between haploid and diploid?

Answers

Answer:

Meiosis is broken down into several stages. Each cell in the process of meiosis involves the cell growing, dividing, splitting, and dividing again in order to produce the four cells at the end of the process. This cellular process is one of the more common processes of biology, but it is also the reason why people have some traits over others.

Explanation:

The difference between mitosis and meiosis is in the process by which each form daughter cells from a parent cell. Mitosis has one round of cellular division and genetic separation whereas meiosis has two rounds.

The key difference between haploid and diploid is that haploid is the state of having half the usual number of chromosomes while diploid is the state of having the usual number of chromosomes in the genome of a cell.

What is terrestrial species?

An animal or plant that lives on land or in the ground, as opposed to the sea, trees, or the air, is said to be terrestrial. There are occasionally aquatic and terrestrial animals seen sleeping next to each other under a loose stone.

These animals can run quickly because the majority of them have legs. They must move quickly to capture their prey or avoid being an animal's next meal (predators). Komodo dragons and red-tailed boas have so many differences, even though they share a common ancestor.

Therefore, Order Urodela has amphibian with aquatic and terrestrial species with very flexible bodies, has a tail, and retains its juvenile features throughout its life.
