List and define the four main elements of the water cycle.
(SCIENCE)
Answers
Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection
Explanation:
Evaporation- Is the the process in which water changes from a liquid to a gas or vapor.
Condensation- Is the process in which water vapor or gas in the air is changed into a liquid. Is the opposite of evaporation.
Precipitation- Precipitation is water from clouds in the form of rain, freezing rain, sleet, snow, or hail.
Collection- This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Also some will soak into the ground and will collect as ground water.

Red blood cells transport oxygen to every cell in the body. This oxygen is needed to release energy stored in glucose molecules. Red blood cells also transport carbon dioxide, a waste product produced by cells, back to the lungs where it is exhaled. When a person exercises, his or her muscle cells consume more oxygen and produce more carbon dioxide. The body responds by increasing its breathing rate and heart rate to supply more oxygen-rich blood to the muscles and carry away more wastes. Explain how this is an example of maintaining homeostasis.

What is the classification of virus
Answers
Answer:
Viruses are classified into 4 groups based on their shape: filamentous, isometric , enveloped, and head and tail.
Many viruses attach to host cells to facilitate penetration of the cell membrane, allowing their replication inside the cell.
The virus core contains the small single- or double-stranded genome that encodes the proteins that the virus cannot get from a host cell.
Explanation:

According to the Baltimore classification system, Viruses are classified into seven classes on the basis of their morphology and function.
What is Virus?A Virus may be defined as a type of microorganism that consists of a nucleic acid molecule in a protein coat and infects cells and may cause disease.
Viruses are classified into seven classes, each of which has its own families of viruses and has differing replication strategies.
Class 1: Double-stranded DNA viruses.
This type of virus usually must enter the host nucleus before it is able to replicate. An Example is Adenoviridae.
Class 2: Single-stranded DNA viruses.
Such types of viruses replicate within the nucleus and pertain highly in vertebrates. An example is Circoviridae.
Class 3: Double-stranded RNA viruses.
Such types of viruses do not depend on host polymerases for replication. An example is Birnaviridae.
Class 4: Single-stranded RNA viruses (positive sense).
Such types of viruses have polycistronic mRNA which is translated into a polyprotein. An example is Flaviviridae.
Class 5: Single-stranded RNA viruses (negative sense).
Such types of viruses must be transcribed by viral polymerases into complementary forms. An example is Filoviridae.
Class 6: Single-stranded RNA viruses (positive sense) that replicate through DNA intermediate.
Such types of viruses use the enzyme reverse transcriptase to convert the positive sense RNA into DNA. An example is Retroviruses.
Class 7: Double-stranded DNA viruses that replicate through a single-stranded RNA intermediate.
Such types of viruses have a double-stranded gapped genome that is subsequently filled into a covalently closed circle that serves as the template for the production of viral mRNA. An example is the Hepatitis B virus.
Therefore, it is well described above.

Explain how mitosis
maintains the chromosome number of the
original cells when forming new cells.
Answers
Mitosis is a type of cell division that helps to maintain the chromosome number of the original cells by dividing cells that previously duplicate their genetic material (DNA) during the interphase (S phase).
The cell cycle is divided into the interphase and the mitotic (M) phase.The interphase of the cell cycle is in turn divided into three different phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.During the S phase, the chromosomes (i.e., the genetic material) of a cell are duplicated.Mitosis is a type of cell division that follows the interphase of the cell cycle by which a somatic (body) cell divides to produce two genetically identical daughter cells.In conclusion, Mitosis is a type of cell division that helps to maintain the chromosome number of the original cells by dividing cells that previously duplicate their genetic material (DNA) during the interphase (S phase).

Calcium, IP3, and cyclic AMP are all small molecules that can be found inside most cells, yet they are known to be important second messengers that can increase or decrease in response to a wide variety of signals. However, each signal often produces completely different responses. Give an example of this phenomenon, and explain how such responses occur.
Answers
Answer:
they are second messenger molecules capable of triggering different signaling pathways
Explanation:
Second messenger molecules are intracellular signaling molecules that trigger different cellular responses. Examples of second messengers include Calcium ions (Ca2+), Inositol trisphosphate (IP3), and cyclic AMP (cAMP). Secondary messengers may be activated by different cellular responses, for example, cyclases that synthesize cAMP or by opening calcium ion (Ca2+) channels. For example, cAMP signaling is able to activate kinase enzymes that perform phosphorylation and interact with other effector molecules to mediate different biological functions (for example, regulation of glycogen and sugar metabolism). On the other hand, Ca2+ signaling is required for muscle contraction, neurotransmitter release, etc. Ca2+ signaling is known to exert allosteric control over enzymes and other types of proteins.

C. It will decrease the percentages of almond and apple crops because lesser numbers of honey bees are available for pollination.
Explanation:
The decrease in honey bees population will affect the ecosystem by decreasing the percentages of almond and apple crops which will lead to lesser numbers of honey bees available for pollination. Almonds and apple crops rely on honey bee colonies for pollination. So, a decrease in the population of honey bees will have an adverse effect on the availability of the crops and food supply. For most variety of almonds, they do not wind pollinate but require cross-pollination in order to produce nut. Other crops that rely on honey bees are watermelon, cucumbers and cherries.
