What is the result when a single cell reproduces by mitosis?
two cells with genetic material identical to the parent cell
two cells with half the genetic material of the parent cell
four cells with half the genetic material of the parent cell
four cells with genetic material identical to the parent cell
Answer: The answer is two cells with genetic material identical to the parent cell.
Explanation: I am also studying this in class and we went over many instances where this question was brought up and the correct answer is four cells with genetic material identical to the parent cell because besides the fact that when you reproduce one cell you get two cells, (which makes logical sense from both a science and a math standpoint) you always have identical DNA to the parent cell and you never get half of it or else it would mess up the whole reproductive process.
The result when a single cell reproduces by mitosis is TWO cells with genetic material IDENTICAL to the parent cell.
Mitosis is a type of cell division by which a parent cell divides to produce two genetically identical daughter cells.
Conversely, meiosis is a type of reductional cell division that produces four daughter cells (gametes) from one parent cell. These cells have half of the genetic material as the original parent cell.
Mitosis divides into four stages: prophase, metaphase, anaphase and telophase.
In conclusion, the result when a single cell reproduces by mitosis is TWO cells with genetic material IDENTICAL to the parent cell.

What is the best way to sample sessile organism with quadrats?
a) Cover the entire area with quadrats
b) Place one quadrat in the center of the area
c) Place quadrats in locations with the most interesting organisms
d) Randomly place quadrats in many locations as possible
Answer:d
Explanation: if you’re doing an experiment you Need multiple trials
The best way to sample sessile organism through the use of quadrats is to: d) Randomly place quadrats in many locations as possible.
Sampling can be defined as a statistical process that is typically used for collecting or selecting data (objects, observations, or living organisms) from a larger statistical population by using a specific procedure.
A quadrat can be defined as a rectangular or square plot that is used to randomly mark off (enclose) an area within a habitat, so as to isolate a sample and determine the percentage of species.
Basically, a quadrat is made of wire and it is usually used for:
Sampling sessile organisms (plants).Sampling slow moving animals such as snails, slugs, etc.In conclusion, the best way to sample sessile organism through the use of quadrats is by randomly placing quadrats in many locations as possible within a habitat.

What is the source of the carbon dioxide that is used in photosynthesis?
sunlight
the soil
the atmosphere
the plant
Answer:
THE ATMOSPHERE
Explanation:
The atmosphere is the source of the carbon dioxide that is used in photosynthesis. Hence option c is correct.
What is photosynthesis?Photosynthesis is defined as the process through which green plants use energy from sunlight to transform carbon dioxide and water into food. It is a process that only happens in plants that contain the chlorophyll, a green pigment used in food preparation. Photosynthesis takes place in the chloroplast, a specialized intracellular organelle found in plants and algae, which emerged considerably later.
During photosynthesis, plants take up carbon dioxide (CO2) and water (H2O) from the soil and atmosphere. Plants take in carbon dioxide from the atmosphere as they photosynthesize. Plants can absorb the gas carbon dioxide from the air by way of microscopic holes in their leaves. Once they have carbon dioxide and water, they can use solar energy to create food.
Thus, the atmosphere is the source of the carbon dioxide that is used in photosynthesis. Hence option c is correct.

How do the Earth, the Sun, and the moon interact to influence the time patters of tides?
Answer:
Explanation:
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides, both commonly called spring tides. A similar situation occurs between the Earth and the sun.

Which organelle is used as temporary storage for water, waste products, food, and other cellular material?
mitochondrion
lysosome
centriole
vacuole
Answer:
d. vacuole
Explanation:
the vacuole stores water, waste, food, etc. and then releases it from the cell.
Organelles are present inside the cells of eukaryotic organisms. The vacuoles of the cells temporarily store water, wastes, food, and other material. Thus, option D is correct.
What is a vacuole?A vacuole is an organelle present in an animal and plant eukaryotic cell. Though they differ in size and number in both cells but have various functions important for the survival of the cell.
The vacuole of plant cells is large than the animal cell and stores the cellular substances, cell waste, and synthesized food particles. In plants, they maintain the water and osmotic balance.
They regulate the storage and transport of cellular materials, maintain turgor pressure, and control the localization of the proteins synthesized by translation.
Therefore, option D. vacuoles stores waste and food.
