Alternation of generation
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"Alternation of generation"
Alternation of generations is the type of life cycle that occurs in those plant and algae in the archaeologist and the heterokontophyta that have distinct haploid sexual and diploid asexual stages.In these groups a multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes made up of n pairs.A mature sporophyte produces haploid spores by meiosis a process which reduces the number of chromosomes to half from 2n to n.
Two haploid spores germinate and grow into a haploid gametophyte.At maturity ,the gametophyte produces gametes by mitosis which does not alter the number of chromosomes.Two gametes from different organism of the same species fuse to diploid zygote,which develop into a diploid sporophyte . This cycle from gametophyte to sporophyte in the way in which all land plant and many algae undergo sexual reproduction.
What is the importance of the amniotic egg?
Answer:
The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land.
Explanation:
An amniotic egg has a clump of nutrients that is used to sustain the embryo during development. This clump of nutrients is called the yolk, and the yolk sac encloses it.

The function of a virus?
the function of a bacteria?
Answer:
the function of a virus is to deliver its genome into the host cell to allow its expression by the host cell. It will, at least attempt to, take over the body and infect the body with the disease virus on it.
the function of a bacteria can be good or bad. for good purposes for example, would be the digestive bacteria that breaks down the food and uses the energy to give the body energy. the bad version of bacteria is to spread from surface to surface, like the flu for example.

What type of inheritance pattern shows both traits in possible offspring
Answer:
Codominance
Explanation:
Codominance is when two dominant traits are equally dominant, and therefore they both are expressed in the offspring's phenotype. For example, if in a flower, blue (BB) and red (RR) are codominant their offspring would be both red and blue. One of the common examples of codominance in humans is blood type, which is seen in AB blood since A and B are equally dominant.
Which of these statements about enzymes is true? Select
all correct answers.
a. Enzymes can help break chemical bonds.
b. Enzymes always change their shape when they bind
to a molecule.
c. Enzymes can break down a variety of different
substances.
d. An enzyme’s shape is related to the shape of the
substrate it binds to.
Answer:
b. Enzymes always change their shape when they bind to a molecule.
d. An enzyme’s shape is related to the shape of the substrate it binds to.
Explanation:
Enzymes are proteins that are secreted by special cells in living organisms. They are the organic catalysts of biochemical reactions.
The role of the enzyme in the enzyme catalyzed reaction is to bring reactants together on its surface so as to have better interactions.
Enzymes have the capability to fit the substrate into an induced fit position.
The process by which enzymes change shape in a reaction is called the induced fit.
This way an enzyme holds the substrate tightly for the reactions to occur.

In this exercise we have to use the knowledge of immunization, in this way we will be able to answer the questions on this topic. So we find that:
1)The invulnerable system, that happen integrated into all concerning living organisms arrangement, protects the body against contamination and different external and within insults by make use of three distinct tier, contingent upon the nature of the danger.
2)Neonates happen physiologically immunodeficient, signification both their native and adjusting immunological reaction are considerably hold in check. In fact, many of the infections gained without special exertion by neonates exist bring about by low-resentment living thing like staphylococcus and pseudomonas.
3)Clinically, the Systemic Inflammatory Response Syndrome (SIRS) exist label by two or more sign of illness or problem containing state of high temperature or agitation.
4) If human growth search out at any time extend beyond 120 old age, methodical study of part of material world give need to guide physically to discourage organ meat disintegration.
5)Active exemption occurs when our own invulnerable method is responsible for guard from harm us from a bacterium. Passive exemption occurs when we exist protected from a bacterium by exemption gained from other person.
In this way we can answer immunization questions such as:
1)The invulnerable system, that happen integrated into all concerning living organisms arrangement, protects the body against contamination and different external and within insults by make use of three distinct tier, contingent upon the nature of the danger: concerning the body and biochemical hurdle, abundant different invulnerable container, and antibodies.
2)Neonates happen physiologically immunodeficient, signification both their native and adjusting immunological reaction are considerably hold in check. Once innate, a child’s immune scheme responds genially to protein antigens and less so to glycoproteins and polysaccharides.
3) Clinically, the Systemic Inflammatory Response Syndrome (SIRS) exist label by two or more sign of illness or problem containing state of high temperature or agitation or hypothermia, heart attack, tachypnoea and change fashionable red body fluid leucocyte count.
4)One habit the physique protects against pathogens and antigens is through humoral exemption. White blood cells produce antibodies that flow through the material’s red body fluid and lymph, also known as the bulk’s humors.
They follow and devastate the pathogens fashionable the humoral systems. T-smallest living organism enhance supply instructions to label a different type of bacterium or irritant. If the invulnerable system doesn’t test T-smallest living organism to be in a dispute or fight a bacterium or antigen, it will initiate something B-small room. These small room identify the pathogen and demolish it through the creating of goods of an antitoxin. They not only produce one type of microscopic organism, but they bear the skill to produce antibodies that exist required to devastate particular ailment.They use up their data banks try to find the often causing illness that will fit accompanying the trespasser, and if one doesn’t be living, they will produce individual over time.If human growth search out at any time extend beyond 120 old age, methodical study of part of material world give need to guide physically to discourage organ meat disintegration.
5)Active exemption occurs when our own invulnerable method is responsible for guard from harm us from a bacterium. Passive exemption occurs when we exist protected from a bacterium by exemption gained from other person.
