c. Genetic mutations
b. Enhanced physical ability

The distance traveled by an object divided by the time it takes to travel that distance is called
a. average velocity.
c. average acceleration.
b. average speed.
d. activity.
B)Seeds are protected and nourished by a fruit
C)The zygote is the first cell of the gametophyte phase
D) Fertilization produces a diploid cell.
Fertilization produces a diploid cell is the common phase that occurs in the life cycle of both the moss and fern. Hence, the correct option is D.
Fertilization refers to the fusion of haploid gametes of the male and female to produce a diploid cell, which is called zygote.
Mosses belong to bryophytes and ferns belong to class pteridophytes. Both undergo sexual and asexual reproduction. They undergo asexual reproduction by the production of spores, while sexual reproduction with the formation of gametes.
Both undergo oogamous mode of sexual reproduction with the formation of zygote that is diploid in nature. It is facilitated by the fusion of non-motile female gamete with the motile male gamete, which is termed as sperm.
Therefore, the correct option is D.

Answer;
D) Fertilization produces a diploid cell.
Explanation;
In mosses; A single spore germinates to form a branched, filamentous protonema, from which a leafy gametophyte develops. The gametophyte bears organs for sexual reproduction. Sperm, which are released by the mature antheridium (the male reproductive organ), are attracted into the neck of an archegonium (the female reproductive organ). Here, one sperm fuses with the egg (fertilization) to produce the diploid zygote.
The life cycle of a fern is very different from the life cycle of many other plants. Ferns have an intermediate stage, called a gametophyte, which then grows into a mature fern. During Gametophyte stge, the spores are produced on the underside of mature plants. These will germinate and grow into small, heart-shaped plants called gametophytes. The gametophytes produce both sperm and egg cells, and will fertilize itself, or others to yield a diploid cell.

Answer:
nervous
Explanation:
The nervous tissue is one of the four basic tissues of the organism, it is formed by two types of cellular elements, it represents the fundamental component of the structures and organs that make up the nervous system. The main function of the nervous tissue is to capture internal and external stimuli and transform them into nerve impulses. All modifications of the external or internal environment and sensory stimuli such as temperature, pressure, light, sounds and taste, among others, are detected, examined and transmitted by nerve cells. On the other hand, the nervous tissue is in charge of coordinating the motor, glandular, and visceral functions of the individual.
Answer;
-The electron transport chain takes place in and across the inner membrane of the mitochondrion.
Explanation;
-The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.
-It functions to make energy in the form of ATP, it is the third phase of cellular respiration.
The electron transport chain for cellular respiration is located in the inner mitochondrial membrane of eukaryotic cells.
Within the mitochondria, which are the "powerhouses" of the cell responsible for generating energy in the form of ATP, the electron transport chain is situated in the inner membrane.
The inner mitochondrial membrane is highly folded into structures called cristae, which provide a large surface area for the electron transport chain components. This arrangement allows for efficient electron transfer and energy production during cellular respiration.
