Summarize photosynthesis and describe how it is part of the carbon cycle

Answers

Photosynthesis is when plants take in carbon dioxide and create glucose and oxygen. It is apart of the carbon cycle because it removes carbon from the air and turns it into oxygen.
Photosynthesis is the action of plants taking in sunlight to make their food. Just like us humanos make our own food they do the same thing when they get sunlight. This is part of the carbon cycle because during photosynthesis plants absorb sunlight and Carbon dioxide and in the end and let out oxygen.

you discover that an atom of an unknown element had 54 protons. identify the element and explain how you know the identity is correct. explain whether the unknown element is more or less reactive than an atom of an element that has 30 protons. identify an element that would have very similar chemical properties (as element 54) to the unknown element and explain why its chemical properties would be similar.

Answers

Answer: Xenon

Explanation:

if you look on the periodic table of elements, youll notice that the only element with 54 protons is Xenon. Hope this helps!!

Protons are the positive charged subatomic particle that lies with the neutron in the nucleus of the atom.

The unknown element with 54 protons will be Xenon.

It is because Xenon is the only element in the periodic table having 54 protons. Element has the same number of protons and electrons therefore Xenon is the element that will have 54 protons.

It belongs to the noble gas group because the outer shell is a filled valence shell that is stable and less reactive compared to other elements.

Therefore it will be less reactive compared to the element having 30 protons.

The elements having similar properties as Xenon will be helium, neon, argon etc because they have the same group in the periodic table.

how are plant cells and human cells the same?
a. they can produce their own oxygen.
b. they make their own food from sunlight.
c. they can receive nutrients through the cell wall.
d. they use mitochondria to release energy from sugars.

Answers

A. They can produce their own oxygen

Plant cells and human cells are similar in the sense that they both use mitochondria to release energy from sugars.

Plant cells and human cells are two distinct kind of cells. Plant cells are autotrophic meaning that they can synthesize their own food using energy from sunlight but human cells are heterotrophic meaning that they depend on other organisms for food.

Despite this huge difference between plant and human cells, they still possess some similarities. One major similarity between plant and animal cells is that they both possess MITOCHONDRIA and use it to undergo cellular respiration.

Cellular respiration is a process that breaks down organic substances like sugars to synthesize ENERGY (ATP). This process occurs in the MITOCHONDRIA of both plant and animal cells.

Therefore, the fact that both plant and human cells use mitochondria to obtain energy is a similarity between them.

Which feature forms as a result of conduction between magma and water?

Answers

Answer:

hot spring

Explanation:

im not entirely sure tbh

Hot springs are formed as a results of conduction of heat between the magma and water. Thus, the correct option is B.


What is Heat conduction?

Heat conduction is the transfer of the internal thermal energy of a system by the collisions of microscopic particles and movement of electrons within a body. The microscopic particles of the body in this heat conduction can be molecules, atoms, and even electrons. Internal energy includes the kinematic and potential energy of the microscopic particles of an object.

Hot springs are formed when the rainwater or the groundwater heats upon by coming in contact with the rocks which have been heated up by the magma, deep beneath the Earth's surface, Hot Spring is formed. This form of geothermal spring generally occurs in the areas near volcanic activities on the planet.

Therefore, the correct option is B.
