The correct answer is to Represent the locations of subatomic particles in different atomic theories.

Explanation:

Atoms, which are the basic unit of matter in the universe are composed of subatomic particles (protons, neutrons, electrons). Moreover, during history atoms have been represented through different models that differ in their general structure as well as the location of sub particles.

This can be seen in the image presented because Thompson's model purposes electrons, which are represented by circles with the negative sign, are distributed inside a positively charged substance. On the other hand, Bohr's model proposes protons are in the center and electrons orbit around it, which shows different locations of sub-particles.

sweet [91]

Answer:

The correct answer is : Hormones in the plant help fruits develop and ripen.

Explanation:

Development of fruits and its ripening is brought about by a number of plant hormones :

Auxin - It promotes the cellular growth, both with respect to cell-division and cell elongation. It promotes the cells in the fruit to expand isodiametrically.
Gibberellic Acid - This hormone delays the ripening of fruits and also prevents senescence. It helps the fruits to acquire enhanced characteristics.
Cytokinin - Promotes cell division during the development of fruit.
Ehylene - Promotes the ripening of fruits.

Answer:

The correct answer is - natural selection process does not move simply to an optimized endpoint.

Explanation:

Natural selection is a process of evolution that helps in evolving populations that are adapted to successfully reproduce and survive according to the environment.

Natural selection does not march simply to an optimized endpoint. Natural selection works upon individual organisms that have advantageous characteristics in specific environments. If the environment changes the advantages can become disadvantageous.

Thus, the correct answer is - natural selection process does not move simply to an optimized endpoint.

dimulka [17.4K]

Answer:

C. mineral

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;

1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

Mineral is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.

Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.
