Atom is the basic element of all living things because it's small. It is the smallest constituent unit of matter which has the properties of a chemical element. They are very small. Sizes are about 100 or 100, 000 fm. They are unstable. They are composed of a nucleus and electrons.

Some have cell walls with lipopolysaccharide.
Ksivusya [100]

Answer:

b. Bacteria

Explanation:

Cell walls with lipopolysaccharide are present in gram Negative bacteria. Gram-negative bacteria have an outer membrane in their cell wall which is composed of lipopolysaccharides.

The lipopolysaccharides are the molecules that have both lipids and proteins. The lipopolysaccharide layer that forms the outer membrane of Gram-negative bacteria is present outside to their thin peptidoglycan layer.

Which of the following statements is true regarding both theories and laws? Change over time
Gemiola [76]
I think the answer is D. ( or supported by observations ). Because theories change over time, they both NEED to be proven, they do NOT go off of consensus, but they do NEED to be supported by observations. 
I hope this helps.

Which law might require you to do some math calculations?
Vadim26 [7]

Answer:

Law 2

Explanation:

Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.

Mathematically, it is given by the formula;

Force = mass * acceleration

Hence, Law 2 might require you to do some math calculations.

For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.

Given the following data;

Mass = 20kg

Acceleration = 0.5m/s²

To find the force;

Force = mass * acceleration

Substituting into the equation, we have;

Force = 20 * 0.5

Force = 10 Newton.

Living things come from other living things through either sexual or asexual reproduction.
Iteru [2.4K]

Explanation:

Organisms don’t have to only reproduce sexually or only reproduce asexually - some animals do both!

When conditions are good, such organisms will reproduce asexually because it is easier. For example, starfish (by fragmentation), slime molds, and water fleas/daphnia (by parthenogenesis) all reproduce asexually when there is plenty of food, minimal predators, and not too much crowding of individuals of the same species.

When conditions worsen (less food, too many individuals, etc), they may switch to sexual reproduction in order to add genetic variation to their population and ensure survival through difficult times.
