1 answer:

8 0

Photosynthesis takes place<span> inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make </span>photosynthesis happen<span>.</span>

"The ____ is the division of the autonomic nervous system that coordinates arousal and involves the expenditure of energy."

finlep [7]

Answer:

Sympathetic nervous system

Explanation:

The sympathetic nervous system is the part of the autonomic system of neurons which gets activated in the condition of stress.

The stress conditions activate the sympathetic nervous system which prepares the human body for the stress condition by either fight or flight mode.

The fight or flight responses requires a large amount of energy which are produced by the activation of the parasympathetic energy therefore the sympathetic system involves the expenditure of the energy. The system is also involved in sexual arousal.

Thus, the Sympathetic nervous system is the correct answer.

Calculate the number of cells in a hummingbird, assuming it has a mass of 10-2 kg.

Nikitich [7]

The number of cells in a hummingbird, given the data is 10¹² cells

<h3>How to determine the mass of one cell</h3>

We'll begin by obtained the mass of a cell. This can be obtained as illustrated below:

Mass of 1 cell = 10 × mass of bacterium

But

Mass of bacterium = 10⁻¹⁵ Kg

Thus,

Mass of 1 cell = 10 × 10⁻¹⁵ Kg

Mass of 1 cell = 10⁻¹⁴ Kg

<h3>How to determine the number of cells in the hummingbird</h3>

The number of cells in the hummingbird can be obtain as follow:

Mass of 1 cell = 10⁻¹⁴ Kg
Mass of hummingbird = 10⁻² Kg
Number of cells =?

Number of cells = Mass of hummingbird / mass of 1 cell

Number of cells = 10⁻² / 10⁻¹⁴

Number of cells = 10¹² cells

Thus, the number of cells in the hummingbird is 10¹² cells

The carbon that plants need for photosynthesis comes from

Anvisha [2.4K]

Answer: The carbon that plants need for photosynthesis comes from carbon dioxide, or CO2 that's present in our atmosphere.

Explanation: Carbon dioxide is released into the air by organisms, such as animals that undergo cellular respiration. In other words, we breathe out CO2 as a waste product.
