What are the outcomes for hares being introduced into the grassland ecosystem
Answer: The correct answers should be the hares will multiply indiscriminately and destroy the ecosystem and the native herbivores will experience increased competition for resources.
Since the hares wouldn't have predators, and they are famous for rapid breeding, they would overpopulate the ecosystem. On the other hand, the native animals would have to compete with this population of hares for food and would have less for for themselves.

Describe where hormones are produced and how they are transported from endocrine glands to their target organs, including the pituitary gland, thyroid gland, pancreas, adrenal glands, ovaries and testes.
Answer:
Hormones are transported through the bloodstream or through fluid around cells.
Explanation:
Once they find a target, they bind with proteins in the cells located in the glands you specified, causing the cells to change activities.
Hormones are the chemicals that are produced by endocrine glands.

Answer:
C.) 2
Explanation:
Just a side note, I just assigned a random letter to work through this problem. It does not matter what you choose.
The carrier genotypes are Aa while any non carriers are AA, and any affected would be aa.
You would go through each of the pairs and do a pedegree to find out the genotypes of the offspring they produce. For 1 it would be a pedegree for Aa from the mom and AA from the dad. There offspring would be 1/2 Aa and 1/2 AA.
For number 2 it would be Aa for the mom and Aa for the dad. There offspring would be 1/4 AA, 1/2 Aa, and 1/4 aa.
For number 3 the mom would have AA and the dad would be aa. There offspring would be 4/4 Aa
For number 4 the mom would be Aa and the dad would be AA. There offspring would be 1/2 AA and 1/2 Aa.
Group #2 are the only set of parents that would produce a offspring that would be affected by the genetic condition, so the answer is C

We have to finish dividing the cytoplasm and then back to work. Can’t wait to get back to normal
The cell cycle is a process characterized by finishing when dividing the cytoplasm and then the daughter cells back to work.
What is the cell cycle?The cell cycle is a series of cellular events that undergo a cell from its formation to its division.
The cell cycle can be divided into an interphase and a mitotic (M) phase, which ends with a process called cytokinesis.
The cytokinesis refers to the division of the cytoplasm, which is required to form two daughter cells.

What are the different systems of classification of organisms
Answer:
kingdom, phylum, class, order, family, genus, and species.
Explanation:
kingdom, phylum, class, order, family, genus, and species.
Classification is a grouping of individuals according to their similarities and differences. It is used to group organisms according to ranks of similar characteristics and evolutionary basis.
What are the levels of classification?Classification system is divided into various levels in order to rank the organisms.
It has following levels:
Kingdom: It is the highest level of classification. There are a total of five kingdoms.Phylum: It is classified on the basis of phenetics and phylogenetics.Class: each phylum can contain multiple class.Family: it is group of genera having similar traits.Genus: it helps to determine species of the organisms.Species: it is the lowest rank in this category. It is group of organisms having similar characteristics.Thus, kingdom, phylum, class, family, genus, species are the classification system of organisms.

Obliquity or tilt is the inclination angle of the Earth's axis. It is responsible for seasonal changes. The correct option is A) The tilt of the Earth is responsible for the seasons.
What is the Earth's obliquity -tilt-?The term obliquity or tilt refers to the inclination of the axis of the Earth. The plane in which the Earth orbits around the sun is not orthogonal to the Earth’s axis of rotation. The axis has an inclination angle called ecliptic obliquity.
Obliquity is a determinant of seasons' existence. Thanks to this inclination in the axis of the Earth there are seasons. If tilt would equal cero, there would not be any season or temperature change in different regions of the Earth. So tilt becomes a significant factor, especially for high latitude areas.
Obliquity is one of the three Milankovitch cycles, together with precession and eccentricity. These are used to explain natural climatic changes through the history of the Earth.
The correct option is A). The tilt of the Earth is responsible for the seasons.

One autumn in the late 1990s, a number of people became ill after working at a single building at an industrial plant in a neighborhood of Baltimore, Maryland. Their symptoms ranged from simple coughing and other respiratory symptoms to pneumonia. At least one of the 70 people reporting symptoms died. He was 78 years old. The company voluntarily closed the building upon the recommendation of the Maryland Department of Health and Mental Hygiene. After all of the water systems at the plant were evaluated and disinfected, it re-opened and no new cases were reported.
1. Health departments often have less information than this when they start hypothesizing about the causative organism and its source. What is your first guess?
2. Describe the transmission characteristics of the suspected bacteria.
3. Is there a risk for a continuing community outbreak from these initial infections? Why or why not?
This disease is likely caused by a bacterium that was transported through the water. If water was infected only locally, likely, there are no outbreaks.
What can be guessed about the causative organism?The causative organism seems to be a type of bacteria in water. This is because disinfecting the water systems seemed to be the problem, which shows the source was there.
How are these bacteria transmitted?The suspected bacteria is transmitted through water. This seems to be the main transmission route because it seems workers experienced symptoms after drinking water.
Is there a risk for more outbreaks?If only the water of the plant was contaminated with this bacteria, it is likely there are no outbreaks. However, if contamination was general, outbreaks might appear.

Explanation: You can tell this because when you look at the diagram it shows B and C facing the sun so that means it's summer.
Answer
D.) C and D
Explanation:
It may look like B and C, but the sun hardly reaches up in the north, plus its axis is shifted so it's not technically summer for them yet, this leaves the bottom, which will rotate and give both sides the taste of summer glory.

how is dna copied in your own words?
Answer:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
Answer:

Will earth run out of water?
While our globe may never run out of water as a whole, it's crucial to realize that pure freshwater isn't always available where and when humans require it. In fact, only six countries contain half of the world's freshwater. Over a billion people do not have access to adequate safe, clean water. Water scarcity will afflict the entire planet by 2040 unless water use is significantly decreased. "If we keep doing what we're doing now, there will be no water by 2040."
