Answer:

Explanation:

Part A: identify organelle X. state the process that this organelle performs

- Mitochondria

- Mitochondria is the powerhouse of the cell. It converts energy from food source into usable chemical energy of the cell, in order to power the cell.

Part B: Identify two materials that are needed for this process to occur, and then identify one molecule produced by this organelle and explain why it’s important to the organism

- Mitochondria need an energy source (like sugar or fat) and oxygen to produce ATP (adenosine triphosphate).

- ATP is the energy currency in a cell. Cells need ATP to power various biochemical reactions in the cell.

Depending on what you have learned about the mitochondria, the following might be included as well.

- Oxidative phosphorylation is a process that happens in the cell to convert chemical energy from food into ATP.

- But I mean A LOT more processes occur in the mitochondria, so much so that university students still learn about it, so I am not exactly sure how in depth your teacher wants.

The given statement is true, the tissue of the capsule in a moss is diploid.

Funaria is moss and it belongs to the dominion Bryophyta. Funaria continues switching among the gametophytic department and sporophytic department phase. The pill and seta belong to the sporophyte which undergoes meiosis to provide spores. In mosses, the dominant level is the haploid generation (the gametophyte). This way that the green, leafy gametophytic tissue is haploid (has handiest one set of chromosomes). Each sporophyte plant consists of a pill, that's the middle of spore formation; a stalk; and a foot that attaches the sporophyte frame to the end of the gametophyte. Eventually, the diploid spores are launched and, upon a hit germination, develop into some other moss plant.

Thus, the given statement is true.

Answer:

Damage to the front association area will likely result in a personality change or disorder.

It depends on the side of the brain that was engaged and the dominant side of the individual. Having said that, the majority of frontal lobe injuries are caused by traumatic brain injury, with vehicle accidents being the main culprit. Traumatic brain injury often causes trauma to the entire brain, on both sides. If you want to witness a "pure" frontal lobe trauma, you should look at persons who have had a tumor in the frontal lobe or a stroke in the area (which is less common than in other places). Since the frontal lobe is often in charge of the brain's "executive" or higher processes, organizing, planning, making decisions, and impulse control would all be impaired.

A likely ecological impact of crop rotation is that it ensures the presence of a single type of nutrient in the soil. (option D)

Answer: Therefore, there will be 15,625 bacteria after 72 hours.

Explanation:

Let N(t) be the number of bacteria at time t. The rate of change of bacteria is proportional to the number of bacteria present, so we have:

dN/dt = kN

where k is the constant of proportionality.

Using the initial condition N(0) = 20, we can solve for k:

N(0) = 20

N(t) = N(0)e^(kt)

50 = 20e^(8k)

ln(50/20) = 8k

k = ln(5/2)/8

Now, we can find N(72):

N(72) = 20e^(72k)

N(72) = 20e^(9ln(5/2))

N(72) = 20(5/2)^9

N(72) = 15625

Therefore, there will be 15,625 bacteria after 72 hours.

The average diffusion distance is 2.1 mm

Explanation:

Given

Diffusion distance of the four potato squares are;

\(Potato 1: 2.1 mm\\Potato 2: 1.8 mm\\Potato 3: 2.3 mm\\Potato 4: 2.2 mm\)

Required

Average Diffusion Distance

To calculate the average diffusion distance; we simply calculate the mean of the student recordings

Mean is calculated as thus;

\(Mean = \frac{\sum x}{n}\)

Where x is the individual distance of the potato squares

\(\sum x = 2.1 mm + 1.8 mm + 2.3 mm + 2,2 mm\)

\(\sum x = 8.4mm\)

n is the number of potato squares

n = 4

\(Mean = \frac{\sum x}{n}\)

\(Mean = \frac{8.4 mm}{4}\)

\(Mean = 2.1 mm\)

Hence, the average diffusion distance is 2.1mm
