The correct answer is A. Phenotypes

Explanation:

In genetics, the observable traits of an organism that includes behavior, physical traits, biochemical properties, etc. are known as phenotypes. These traits depend on both the genes of the organism (genotype) and the influence of the environment. Due to this, organisms of the same species with a similar genotype can display different phenotypes. This occurs in the case of Patrick and Michael as their observable traits or phenotype is different despite they are brothers. Thus, the observable characteristics are the phenotypes of an organism.

Complete Question:

1. Organisms don’t all reproduce the same way. However, by comparing the ____ of these organisms, many similarities between them are ____

2. of these organisms, many similarities between them are revealed. These similarities suggest that they’re ___ linked. This type of study is called developmental biology.

Group of answer choices.

A) Cells B) Embryos C) Mode of reproduction D) Evolutionarily. E). Revealed.

Answer:

embryo; revealed; evolutionarily.

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

It's a fact that all living organisms do not reproduce the same way.

However, by comparing the embryo of these organisms, many similarities between them are revealed. These similarities suggest that they’re evolutionarily linked.

Hence, we refer to this type of study as developmental biology

Answer:

The Moon, otherwise known as Luna, is the only natural satellite of Earth. It was created 4.6 billion years ago, and it is widely accepted that it was created when Earth collided with a planet-sized object called Theia. It’s the fifth-largest moon in our solar system and is the second brightest object in the sky (after the Sun).

Explanation:

History of The Moon

Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies.

The Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon’s phases. The time between successive new moons is 29.5 days (709 hours), slightly different from the Moon’s orbital period (measured against the stars) since the Earth moves a significant distance in its orbit around the Sun in that time.
