If element X has 15 protons, how many electrons does it have?

Answers

Answer 1
Answer: If element X has 15 protons, it would also have 15 electrons.
Answer 2
Answer: If the element has 55 protons it is celcium and it also has 55 electrons. It has an atomic mass of 133 (132.9) so to get the number of neutrons you subtract the atomic mass and the number of protons.

Answer:

Lipids!

Explanation:

Lipids are made up of Oils that, when mixed in water or other chemicals, will separate. Since Oils do not mix and float to the top, and since Oils are a type of lipid, the answer is Lipids!

What do plants do with the molecules made
during photosynthesis?

Answers

Answer:

Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2). The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development

Explanation:

The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower formation, and fruit development.

Which theory suggests that cells are the basic building blocks of life but don't constitute life itself?Cell theory or organismal theory?

Answers

Answer:

The correct answer would be the organismal theory.

The three main principles of the cell theory are:

  • All the living organisms are formed by one or more types of cells.
  • Cell forms the basic structural and functional unit of all living organisms.
  • Cell arises from the pre-existing cell.

The organismal theory was developed as a counter argument towards the cell theory.

One of the principles of this theory states that "cells are the basic building blocks of life but don't constitute life itself". For example, cells removed from a multicellular organism require specific life support systems in order to keep them alive.

This is the organismal theory: the theory that the basic unit of life is the organism, but which can be divided into cells.

Cell theory says that the basic unit of life is the cell.

Which of the following statements best describes the structure and function of a carbohydrate?A. Carbohydrates are made up of starchy monomers and are used for structure, protection, and reproduction.
B. Carbohydrates are made up of sucrose molecules that are important for transportation and protein synthesis.
C. carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.
D. Carbohydrates are long, winding molecules made up of amino acids and are important in the synthesis of fats and hormones.

Answers

Answer: The correct answer is C. Carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.

Carbohydrates are the large group of organic compounds, which are comprised of Carbon, hydrogen, and Oxygen. They mainly include simple sugar (like glucose, fructose) and starch ( present in food like potato, grains).

They are the most essential and readily available source of energy for all life forms.

Complex carbohydrates ( polysaccharides) like starch are made up of simple sugar called monosaccharide ( like glucose).

Thus, option C) is the right answer.


Final answer:

Carbohydrates are large molecules made up of monosaccharides and are used by organisms primarily for energy storage.

Explanation:

The statement that most accurately describes the structure and function of a carbohydrate is 'Carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.' Carbohydrates are indeed large, complex molecules that are composed of smaller subunits known as monosaccharides.

They serve several essential functions in organisms, one of the most critical one being the storage and provision of energy. When organisms ingest carbohydrates, these molecules are broken down and converted into glucose, which is then used to fuel various cellular activities.
