What happens to the energy that is passed to the primary consumer
Answer:Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. ... At each level, called a trophic level, about 90% of the energy is lost.

Name two possible causes of the largest mass extinction in Earth’s history and explain how this both helped and hurt different species.
Answer:
Explanation:
Two possible causes for the biggest mass extinction event in the history of our planet would be an asteroid impacting the planet and the massive volcanic activity. This mass extinction event is called the Permian-Triassic extinction. This helped many species emerge as survivors and thrive without the oppressive bigger species that died out. It hurt many species that were unable to survive the harsh conditions that resulted from everything that was happening to their habitats and food sources.

Which organelle plays an important role during mitosis, helping to move chromosomes around the cell
a
Oь
Ос
Od
vacuoles
Golgi bodies
chloroplasts
centrioles
Answer:
Explanation:
Duplicated centrioles are responsible for moving chromosomes during mitosis.
They are involved in the formation and organization of spindle during cell division (mitotic phase) and also in the process of cytokinesis.
It is composed of nine triplets of microtubules that are the proteins of cytoskeleton.
Spindle fibres contain multiple proteins that help in the binding with centromere during cell cycle.
They originate from the poles of the cell by the organelle called centriole, and attached to the kinetochore of the chromatid.
Many spindle fibres are just connected between two poles, as they are not attached to the chromatids.
These fibres orient the chromosomes into pairs, to the metaphase plate into a line during metaphase.
During anaphase they are shortened, which pulls the chromosomes to the opposite poles separated from the pairs.
At the end in telophase, where nuclear membrane becomes visible it disappears.
In this way the spindle fibers help in the separation of chromosomes into two new daughter cells. This process is also known as the distribution of heredity or genetic information between new cells.
If transpiration didn't take place, would water be able to enter the roots of the plant? Explain your reasoning
Answer:
Yes
Explanation:
If transpiration do not occur water will enter the roots of the plants because water enter through the roots by osmosis and move to the xylem vessels after which it get to the leaves and it is lost by evaporation and transpiration. Transpiration is the process why by water is loss through the stomata opening of the leaves and this help in exchange of gases, reduction of excess water and help in plant growth.

Explanation:
When an organism can tolerate specific chemicals meant to kill it, it is said that the organism has developed a(n) ______________________ to the chemical.
Answer:
Immunity.
Explanation:
The organism has developed an immunity to the chemicals meant to kill it. An immunity allows the organism to not be effected anymore by it and survive.
Hope this is correct, have a great day!
When an organism can tolerate specific chemicals meant to kill it, it is said that the organism has developed an Immunity to the chemical.
What is meant by the term Immunity ?Immunity pertains to an individual body’s ability to restrict the incursion of pathogens. Pathogens are foreign disease-generating substances, which includes bacteria and viruses, and humans are susceptible to them on a daily basis.
Antigens are attached to the surface of pathogens which further arouses an immune response in the body of an individual. Immune response or immunity refers to the body’s capability to defend and to fight against antigens and protect the body.
There are various types of immunity, which consists of innate immunity, passive immunity, and acquired/active immunity.\
1) Innate immunity refers to standard protection that a person is born with already acquired since birth, consisting physical barriers (skin, body hair), defense mechanisms (saliva, gastric acid), and generic immune reactions (inflammation).
2) Passive immunity refers to an individual body’s ability to resist pathogens by “borrowing” antibodies. For illustration, antibodies could be transmitted to a baby from a mother’s breast milk, or via blood products consisting antibodies like immunoglobulin that can be diffused from one person to another.
Thus, when an organism can tolerate specific chemicals meant to kill it, it is said that the organism has developed an Immunity to the chemical.
