Answer: C) ciliates.

Explanation: Ciliates possess two different nuclei a diploid micronucleus which carry the germline of the cell. It also has a large, polyploid macronucleus which can be termed the vegetative nucleus, it takes care of general cell regulation, it expresses the phenotype of the organism. The macronucleus is generated from the micronucleus. The micronucleus passes the genetic material to offspring, but it does not express its genes. The macronucleus provides the small nuclear RNA for vegetative growth.

Answer:

C-Ciliates

Explanation:

These are motile protozoan, with short, large number of  organs of locomotion called  Cilia. These cilia move up and down in various pattern in their  aquatic in habitat.

The two nuclei  are  the generative nucleus which is concerned with the  transmission of hereditary materials, and the larger Vegetative nucleus  that  coordinate    expression of the phenotype  traits and regulation of cell activities.

<u>The 9+2 filament pattern of the cilia  refers to the arrangement of the microtubules that  made up the cilia. Figure 9 refer to the cylindrical arrangement   of  9 fused miroctubles found at  the outer layer of Cilia, while the other 2 microtubules which are not fused ,  occupy  the center of the fused mircrotubules </u>. This represent fig 2. Therefore  outer 9 plus inner 2, gives 9+2 filament pattern. This arrangement makes cilia  to have different undulation.

Compare and contrast Darwin’s theory of evolution to the ideas of Lamarck.
Nitella [24]

Answer:

Darwin and Lamarck were both scientists who tried to understand evolution. ... Darwin's theory became accepted because it had more evidence that supported it. Lamarck's theory suggest that all organisms become more complicated over time, and therefore doesn't account for simple organisms, such as single-cell organisms.

What is the purpose of atp in both cellular respiration and photosynthesis?
Stells [14]

Answer:

Aids energy transfer from a molecule to another

Explanation:

ATP aids energy coupling, combining exergonic reactions to endergonic reactions. In PHOTOSYNTHESIS, ATP is produced in the light reactions for Calvin cycle to produce sugar. In CELLULAR RESPIRATION, sugar undergoes oxidized to produce ATP needed to energize cellular metabolism (ATP is the energy currency of the cell).

ATP is a major source of energy for each and every biological process. In PHOTOSYNTHESIS energy is changed to ATP in the light-dependent phase which is used for synthesis in the dark phase.

ATP is a needed in RESPIRATION. ATP is the energy currency of the cells, sometimes called the “molecular currency” of energy distribution.

what is the name for a system formed by the interaction of living organisms with the nonliving physical environment?
iogann1982 [59]

Answer:

Ecosystem is the the name of the natural or artificial system in which living organisms interacts with the non-living physical environment. The living components are called as biotic factors which includes plants, animals, birds and human beings. The non-living components includes sunlight, temperature, weather conditions, water and soil. The living components of the ecosystem are dependent on non-living components for performing their biological functions like respiration, photosynthesis and others.

Helga [31]

Answer:

Conduct an experiment.

Explanation:

Any scientific hypothesis or theory requires the proper step and the procedure to explain the particular points about the theory. Any statement made in the science needs the experimental proof.

The scientific experiments includes the different steps used for the validation of any hypothesis. The experiments can explain the main cause of any phenomena and the factors that might affect the experiments. The experimental studies are performed by the scientists.

Thus, the correct answer is option (e).
