Answer:

Chlorophyll

Explanation:

because they lack roots, stems, and leaves.

The component that can be found in non-vascular plants is chlorophyll. The correct option is C.

Chlorophyll is a pigment that gives plants their distinctive green colour and aids in photosynthesis, which enables plants to produce their own food.

Plants (including algae) can photosynthesize, or use sunshine to change simple molecules into organic compounds.

Chlorophyll makes this possible. The most common kind of chlorophyll found in algae and green plants is chlorophyll a.

Plants lacking a circulatory system made up of xylem and phloem are referred to as non-vascular plants. They may instead have more basic tissues with tailored capabilities for the internal transfer of water.

Mosses, hornworts, and liverworts are examples of nonvascular plants. They don't have leaves, stems, or roots.

Nonvascular plants require a damp environment, are low-growing, and reproduce using spores.

Thus, the correct option is C.

Answer:

S- phase replication.

Explanation:

Genetic material present within DNA molecules regulates cell growth, proliferation, and cell repair. The long-chain helical macromolecules of these deoxyribonucleic acids are formed from complex sequences called nucleotides; these four monomers are joined by strong covalent bonds (adenine, cytosine, guanine, thymine).

DNA coding regions are called genes-they hold the cell's basic instructions. Multiple nucleotides and even several chromosomes may contain genes. Typically, gene expression entails transcription into RNA, and translation into amino acids/ proteins. In the S phase of the cell cycle, DNA is copied by polymerases. Here, the chromosomes are unwound and DNA is copied during replication to produce identical strands.

a. Tan seed is dominant with an allele TT. It effect dominate that of red seed indicating it is a dominant traits while red seed is a recessive traits.

A dominant trait is a traits that is expressed in the phenotype of an organism the F1 generation are all Tan seeds this shows that the trait is dominant.

The genotype of the F1 melon is Tt in a dominant form

The F2 result follows the mendelian principle where segregation occur leading to a phenotypic ratio of 3:1

The particles of the substance initially had high Kinetic Energy.​

Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.

In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

The time taken by the sound waves traveling through the air will be 2.87 seconds.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The air that is 68°F to travel 1,372 meters.

68°F = 293.15 K

The velocity of air is given as,

v = 331.3 × √[1 + (T / 273.15)]

v = 331.3 × √[1 + (293.15 / 273.15)]

v = 477.028 m/s

Then the time taken is given as,

t = d/v

t = 1372 / 477.028

t = 2.87 seconds

Enzymes are a type of catalyst.

Animals and other organisms obtain the energy available in carbohydrates through the process of cellular respiration.

When we say cellular respiration it is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.

The relationship between these two is that cells take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrates and release the energy (cellular energy).
