Explanation:
An organelle is a specific structure within a cell, and there are many different types of organelles. Organelles are also called vesicles within a cell. ... So really, organelles are all membrane-bound. And they separate one function from another function.
Organelles is also known as any of a number of organized or specialized structures within a living cell. Three organelles contain DNA: the nucleus, chloroplasts, and mitochondria.
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.

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.

Many pine trees grow in the taiga, the largest habitat in the world. Using credible sources, such as NASA, research the typical climate conditions in the taiga. Explain why the structure of pinecones helps ensure successful reproduction in the taiga.
Answer:
Explanation:
Taigas have few native plants besides conifers. The soil of the taiga has few nutrients. It can also freeze, making it difficult for many plants to take root. The larch is one of the only deciduous trees able to survive in the freezing northern taiga.

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.
