true
false
The answer for this question is True.
plants conduct photosynthesis,
plants are multicellular
Answer: plants have roots, stems, or leaves
Algae and plants are similar organisms because both are autotrophic organisms which are able to produce their own food by the process of photosynthesis. The main difference between the two is the level of complexity. Algae are comparatively simple organisms, their structure ranges from single celled to multi-cellular organisms. They do not exhibit true roots, stems and leaves like plants. The plants exhibit complex specialized structure for transport of water, nutrients and to perform reproduction. The smallest to largest plant will exhibit roots, stems and leaves.
True statements: A (Water is made up of atoms bonded to form molecules) and D (The chemical formula for water is H₂O).
False statements: B (Water contains half as many hydrogen atoms as oxygen atoms) and C (Water molecules tend to push away from each other)
Let's examine each statement to determine its accuracy:
A) Water is made up of atoms bonded to form molecules.
True: Water is indeed composed of molecules. Each water molecule consists of two hydrogen atoms covalently bonded to one oxygen atom, forming the H₂O molecule.
B) Water contains half as many hydrogen atoms as oxygen atoms.
False: The chemical formula for water, H₂O, indicates that there are two hydrogen atoms for every one oxygen atom in a water molecule. Therefore, water contains twice as many hydrogen atoms as oxygen atoms.
C) Water molecules tend to push away from each other.
False: Water molecules exhibit a property called cohesion, where they are attracted to each other due to hydrogen bonding. This attraction causes water molecules to "stick" together rather than push away from each other. It's why water forms droplets and has a relatively high surface tension.
D) The chemical formula for water is H₂O.
True: The chemical formula H₂O accurately represents the composition of water, indicating that each water molecule consists of two hydrogen atoms and one oxygen atom.
The structure of water involves H₂O molecules, with each molecule consisting of two hydrogen atoms and one oxygen atom, and water molecules exhibit cohesion due to hydrogen bonding, causing them to attract and stick together.

The question probable may be:

D) The chemical formula for water is H₂O.
The skin is the answer. It is an organ of protection.
The skin is made up of two layers namely the epidermis and the dermis. Under the dermis is found hypodermis which is subcutaneous fatty tissue.
The skin has three major functions namely protection, regulation and sensation. When the skin is broken, i.e. wounded, all these functions are affected.
The skin acts as a barrier, providing protection from radiation from the sun, mechanical impacts, pressure and changes in temperature, as well as from microorganisms and chemicals.
integumentary that's the answer
A person should eat energy bars and they should eat energy drinks because it supplies a good amount of carbohydrates (sugar) that can quickly convert inside your body to energy.
(Some good examples of energy drinks would be the brand 'Gatorade')
I am not so sure what exact brand of energy bars to eat, but I know for a fact that each energy bar contains carbohydrates, so probably any energy bar would work. :)

to be honest im not for sure because you don't have any answer choices
