Answer:
Stabilizing selection is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value.
directional selection is a mode of natural selection is an extreme phenotype is favored over other phenotypes.
Disruptive selection describes changes in population genetics in which extreme values for a trait are favored over intermediate values.

Identify and describe the two main parts of a chloroplast where photosynthesis occurs.
The two main parts of a chloroplast where the process of photosynthesis takes place are stroma and granum. The sunlight is trapped in the chlorophyll molecules which results in photosynthesis.
What is Photosynthesis?Photosynthesis is the process of formation of carbohydrates (sugars) in the chloroplast of the plant. Oxygen gas is also evolved in the process of photosynthesis. The sunlight is responsible for the conversion of carbon dioxide and water into carbohydrates and oxygen molecules.
Sunlight is trapped into the chlorophyll molecules present in the cells of leaf in plants. The photosynthesis process is divided into two phases- light reaction and dark reaction. These reactions takes place in the granum and stroma of chloroplast. The light reaction takes place in the stroma while the dark reaction takes place in the granum of chloroplast.

A spaceship to the moon covered the 386,400 km in 72 hours. What was the average speed?
Answer:
1.49 m/s; 5.367 × 10⁶ m/hr
Explanation:
Calculations: (This was my thought process, sorry)
386400 km ÷ 72 hr ≈ 5367
5367 × 1000 = 5.367 × 10⁶
5.367 × 10⁶ ÷ 3600 ≈ 1.49 m/s
About 5367 km/hr or 5.367 × 10⁶ m/hr or 2.592 × 10⁵ m/s

Why would combining cells that result from Mitosis not work for fertilization?
Pls pls answer I need help!
Answer:
Because cells that result from mitosis are diploid i.e. contain two sets of chromosomes.
Explanation:
Mitosis is a type of cell division that produces daughter cells that are genetically identical to the parent cell. The chromosomal number of cells formed from mitosis remains the same as the parent cell. This means that if a parent is diploid (2n), the daughter cells from mitotic division will be diploid (2n).
However, for fertilization during sexual reproduction to occur, two haploid or half of the chromosome number of the parental organism must unite to form a whole diploid organism. In other words, two haploid cells (n + n) must come together in fertilization to give a diploid cell (2n). Hence, combining cells that result from mitosis would not work for fertilization because cells that result from mitosis are already diploid i.e. contain two sets of chromosomes.

the energy required to lift an object is supplied by ATP, which is made by breaking down molecules of
a. carbon dioxide
b. oxygen
c. glycolysis
d. glucose
The energy provided by ATP is driven by the breakdown of glucose molecules. Thus, option D is correct.
ATP or Adenosine triphosphate is the energy molecule that is able to provide energy to the body. Varying pathways and cycles in the cell produce ATP.
Which molecules produce ATP?ATP production is carried out in the degradation of the complex molecules by the cell. The cycle is operated primarily in the cell for the production of ATP in glycolysis.
The ATP is produced in the glycolysis cycle with the breakdown of glucose molecules. Thus, option D is correct.

Construct a food chain. Place the organism in order from producer, primary consumer to secondary consumer to tertiary consumer. (An owl eats a snake, the snake eats a squirrel, the squirrel ate a nut.)
Answer:
nut is the producer the squirell the primary cosumer a snake is the secondary consumer the owl is a terriary consumer
In the given scenario, nut is producer, squirrel is primary consumer, snake is secondary consumer and owl is tertiary consumer.
What is a food chain?The food chain depicts how living things obtain food. Some animals only eat plants, while others eat other animals. The food chain is made up of four types of organisms: producers, consumers, prey, and predators.
Food chains are significant because they reveal the intricate relationships that exist in ecosystems.
They can reveal how each organism is dependent on another for survival. Food chains also show what happens when there is a problem and a producer or consumer is lost. Entire communities can be destroyed.
The nut is the producer, the squirrel is the primary consumer, the snake is the secondary consumer, and the owl is the tertiary consumer as per the given situation.
Thus, the food chain here is nut--->squirrel--->snake--->owl.

Each cube represents a cell. Which cell would probably have the easier time moving materials into and out of itself quickly enough to survive?
Hello. You did not present the cubes to which the question refers, which makes it impossible for me to be able to answer your question exactly, but I will try to help you in the best possible way.
The cell that will have the easiest movement of materials in and out of itself is the cell with the smallest size. This is because, smaller cells have a proportional surface area and volume. This helps in absorbing everything the cell needs, with impressive speed, as well as facilitating the removal of substances harmful to the cell.
