Answer:

Antigens

Explanation:

Antigens can be defined as molecules that can bind to antibodies. Many authors prefer to define it as any substance capable of eliciting a response from the immune system, however there are antigenic substances that react with the antibody but are not able to stimulate its production.

Antigens are usually unknown molecules in the body. Molecules that detach from foreign cells such as bacteria, fungi, protozoa or even viruses can be considered antigens. Toxins released by bacteria are also examples of substances that can bind to antibodies.

When an individual's blood-type alleles have instructions that direct the construction of a specific set of chemicals that protrude from all red blood cells, these chemicals are the antigens.

The enzyme amylase can break glycosidic linkages between glucose monomers only if the monomers are in the alpha form. Which of t
Leto [7]

Answer:

The correct option is: a. glycogen, starch, and amylopectin

Explanation:

Glycogen, amylopectin and starch are the polysaccharides of glucose. These polymers are composed of monomeric α-glucose units, which are joined by α(1→4) glycosidic bonds.

Since, the amylase enzyme can act only on the glycosidic bonds formed between α-glucose monomers. Therefore, amylase can break down glycogen, starch, and amylopectin.

An organism has two types of cells: diploid somatic cells and haploid gametes. How does this organism reproduce? A. Sexually B.
kenny6666 [7]

Answer:

A. sexually

Explanation:

The organism has haploid gametes. Human sex cells (egg and sperm cells) contain a single set of each chromosome, making them haploid. During fertilization, the organism acquires a set of chromosomes from each parent, making it a diploid (two sets of each chromosome) zygote.

Hope this helps.

- Start with the P generation with the following genotypes (AA x aa). Based on classical Mendelian inheritance, how will a cross
nexus9112 [7]

Answer:

<em>The correct option is Although the F1 generation will all show the dominant trait, the offspring  will all be heterozygous and increase chances of future variation.</em>

Explanation:

The cross for the offsrings that will be produced by F1 generation is shown below:

         a          a

A      Aa       Aa

A      Aa        Aa

As we can see that all the offsprings in the F1 generation will have heterozygous genes but only the dominant trait will be seen in the phenotype of the F1 generation.

A cross between the F1 generation will give the following results:

         A          a

A      AA      Aa

a       Aa      aa

This cross shows that there will be increases genetic and phenotype variations in offsprings that will be produced by the F1 plants.

Deine kinetic energy and thermal energy. Describe what
Nikitich [7]

Answer:

Explanation:

Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object. As thermal energy comes from moving particles, it is a form of kinetic energy.
