Assuming these are carbon dioxide molecules, which way do you think the molecules will move and why?

ANTONII [103]

Answer:

A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)

Explanation:

Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata (Figure 3b).

Amy is riding on a train. She wants to sit at the front of the train for a better view, so she gets up to change her seat. Just

Alexus [3.1K]

Answer:

Have you ever been in a bus, a train, or a car ?

What happens to you when it stops suddenly ?

A body in motion continues in motion unless

an external force acts on it and makes it stop.

Amy's body keeps moving forward when the train stops.

She pitches forward, and if she doesn't reach out and grab

a seat or a seated person, she may lose her footing and fall

on her face.

Choice - 'A' is a very good explanation.

The other choices aren't.

'C' is a good hunch, but it only applies to her feet.

The rest of her keeps going.

'D' is nonsense. There are no mysterious forces of

'repulsion' or 'attraction' on the train.

Why do we compare the dermal tissue of plants to human skin? Explain your answer.

Over [174]

Answer:

They are like each other

Explanation:

Your skin covers your body, protecting it from abrasion, water loss, and infection and secreting conditioning substances. The epidermis of a plant serves similar functions. Usually a single layer of closely-packed cells, epidermal tissue covers leaves and young stems and roots of vascular plants. Most epidermal cells secrete waxy substances which form a cuticle, or waterproof covering, over the aerial surfaces of the plant, such as the stems and leaves. The cuticle also resists viral, bacterial, and fungal invasion.

Given that the commercial strawberry is an octoploid organism (8n), how many copies of each gene is present in one of the somati

DanielleElmas [232]

Answer:

1. 8 copies of each gene in somatic cells

2. 4 copies of each gene in gametes

Explanation:

According to the question, strawberry is an octoploid organism (8n). This means that it contains 8 sets of chromosomes in its genome. If it contains 8 copies of each chromosome, then it also contains 8 copies of each gene in its body or somatic cell (4 copies from each parent).

However, it will produce gametes or reproductive cells via meiosis. Meiosis is a kind of cell division that reduces the chromosomal number by half. Hence, an octoploid strawberry (8n) with 8 copies of genes will undergo meiosis to produce gametes that have 4 copies of each chromosome and hence, four copies of each gene i.e. 4n (tetraploid).
