Can you please help me I am super stuck

Biology
1 answer:
Reika [66]3 years ago
3 0

Answer:

a.) 12 Newtons

b.) Same Direction

c.) Unbalanced

Explanation:

The system shows 2 individual forces:

A force of 5 N pulling the box LEFT

A force of 7N pushing the box LEFT

Both forces are LEFT, so they have the same direction.

Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:

Resultant force's magnitude is then: 5N + 7N = 12N

Resultant force's direction: unchanged = LEFT

Since the resultant force's magnitude is not 0, the system is unbalanced.

7. Which molecule is light energy temporarily stored in before being used to make glucose?
BlackZzzverrR [31]

Answer:

The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light

Leno4ka [110]

Answer:

1. b. Crista is s constituent part of mitochondrion.

2. c. Gobi complex and nucleus are separate structures with no particular relationship to each other.

Explanation:

The crista is an integral part of the mitochondria. As you already know, mitochondria is a cytoplasmic organelle. it has two members that delimit it, the outer membrane is completely smooth, however the inner membrane is composed of numerous folds, that are called crista, and that spread through the interior of the mitochondria. These crista have as main function to increase the surface of the inner membrane.

The Golgi complex is a cytoplasmic organelle, as is mitochondria. The nucleus, however, is a cell structure, it is totally separated from the golgi complex and there is no particular relationship between these two structures.

The golgi complex participates in the storage and distribution of substances in the cell, while the nucleus is responsible for housing and protecting genetic information.
