IN YOUR OWN WORDS
DONT COPY FROM THE INTERNET

Answers

Answer:

sugar

Explanation:

sugar is the required macromolecule

In the lactic acid formation, pyruvate changes to the lactose which is the anaerobic form of respiration. Pyruvate changes to alcohol and carbon dioxide.

What is the main ingredient for lactic acid fermentation ?

It is the sugar molecule that is needed for the lactic acid fermentation.

Both the  types of  the fermentation requires two primary components which are a sugar supply and  bacterial culture where alcohol fermentation uses the  forms of  the yeast where the lactic acid fermentation usually depends on  the lactic acid bacteria.

Lactic acid fermentation takes place in some of the  strains of  the bacteria and in  the even skeletal muscle and even  produces lactic acid . Alcoholic fermentation takes place in the  yeast and just  produces ethanol with carbon dioxide.

Lactic acid bacteria is a type of gram-+ve bacteria which use carbohydrates as only and main carbon source. Later on lactic acid bacteria is generally cocci or rods usually have the  strong tolerance to low pH.

[tex]\Large\textbf{ACTIVE AND PASSIVE IMMUNITY}[/tex]

Active Immunity, Immunity which is acquired by the own immune response of the body.

Passive Immunity, Immunity which is acquired and dependent upon the antibodies transported from another person or even an animal. A person's immune system does not acquire or make the antibodies itself. A newborn baby acquires passive immunity from its mother through the placenta.

                            x---------------------------------------------------x

[tex]\Huge\text{Vaccination:}[/tex]

Vaccination is a artificial active immunity. Artificial because the antibodies are not acquired by any natural infection but it is injected into the healthy body of the person. It is Active immunity because the body does not get already made (from other animal) antibodies but it acts on the small amount of the pathogen which is injected in the body and acquires the antibodies itself. So the person acquires antibodies naturally acting on the antigen. Antigen is any foreign agent which triggers the immune system to produce antibodies against it. Vaccines contains antigen which is a harmless form of the bacteria or a virus that causes the disease you are being immunised against. The bacteria or virus are in small proportion and greatly weakened in the vaccine so they just trigger an immune response without causing any real damage. When Vaccine is injected in the body, the immune system starts to make antibodies of different forms against the antigen(Virus or bacteria in the vaccine). When the appropriate shape antibody reacts with the antigen and forms antibody-antigen complex which destroys the antigen. This means that type and shape of antibody is perfect to work against that antigen, then the immune system start forming only those kind of antibodies in great proportion and the Person gets immunised by the vaccine in a natural way.

Answers

Answer:

predators

Explanation:

The correct answer is predators. An alien species that finds plenty of food and suitable habitat in its new home is usually able to find mates and reproduce well. But the competing species may become endangered or even extinct, because the alien (now invasive) species has no natural predators in the new environment, and its population can therefore grow without limits.

You learned in the reading that some symbiotic relationships are helpful and some are harmful. Look at the symbiotic relationships listed below and select all where at least one organism is harmed (the reading calls these harmful relationships). Group of answer choices Commensalism Parasitism Mutualism Predator-Prey Competition

Answers

Answer: Parasitism, Predator-Prey, Competition

Explanation:

The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.

The ability to curl the tongue in dominant to the inability to do so. If Eric (heterozygous tongue curler) marries Brandy (also heterozygous) what are the predicted GTs and PTs of the offspring?

Answers

Answer:

Genotype = 1CC: 2Cc: 1cc

Phenotype = 3 tongue curler : 1 non-tongue curler

Explanation:

This question involves a single gene that codes for the ability or not to curl the tongue. The ability to curl the tongue (C) is dominant to the inability to do so (c). This means that a heterozygote will be able to curl his/her tongue.

According to this question, If Eric, who is a heterozygous tongue curler (Cc) marries Brandy who is also heterozygous (Cc) i.e. Cc × Cc, the following gametes will be produced by each parent: C and c.

Using these gametes in a punnet square (see attached image), the predicted genotype of the offspring is 1CC: 2Cc: 1cc while the predicted phenotype is 3 tongue curler : 1 non-tongue curler.
