Answer:

1. Flower-The biological function of a flower is to affect reproduction, usually by providing a mechanism for the union of sperm with eggs.

2. leave-Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food

3. Stem-The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots

4. Roots-Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels ( xylem )

How many grams of the compound in the figure above are required to make 1 liter of a 0.5 M solution? (Note: The atomic masses, i

Dafna1 [17]

Answer:

This question is incomplete as there is no figure in the question but the compound in the figure is Ethanoic acid (CH3COOH). Hence, we can calculate the mass.

The answer is: 30grams

Explanation:

According to the question, the volume of the compound (CH3COOH) is 1litre while the molar concentration is 0.5M

Molarity or Molar concentration is calculated using the formula:

M= n/V

Where; M= Molarity (M) = 0.5M

n= number of moles (mol)

V= Volume (V) = 1L

Hence, number of moles (n) = M × V

n = 0.5 × 1

n = 0.5 moles.

To calculate the mass in grams of CH3COOH, we say;

Number of moles (n) × molar mass (MM)

Since atomic mass for (C= 12, H= 1 and O=16)

Molar mass of CH3COOH:

= 12 + 1(3) + 12 + 16 + 16 + 1

Molar mass of CH3COOH = 60g/mol

Mass (in grams) of CH3COOH = 0.5 moles × 60g/mol

Mass = 30grams.

Therefore, 30grams of CH3COOH compound are required to make 1 liter of a 0.5 M solution.

In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.

<h3>How does mitosis occur in plant cells?</h3>

In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.

With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.

katrin2010 [14]

Answer:

The correct answer will be option-D.

Explanation:

In the given question doctor used the scientific method to understand and explain the natural phenomenon.

The scientific method involves various steps like making an observation followed by background research, predicting a hypothesis and performing tests to test the hypothesis. These steps have been performed by the doctor.

After these steps the doctor will analyse the result and reach to the conclusion. This would be followed by publishing the results in a scientific journal where it would be reviewed by the fellow scientists.

Therefore, the next step will be publishing the result and thus option-D is the correct answer.

LuckyWell [14K]

Answer:

Change in chromatin structure-------Acetylation of histones facilitates transcription

Activity of transcription apparatus------Transcriptional activators increase promoter activity by interacting with the RNAPII holoenzyme

RNA processing---------Alternative splicing produces different transcripts from the same gene.

RNA interference-------A siRNA and the transcript it targets is transcribed from the same gene.

Initiation of translation-------Limited availability of initiation factors prevents translation of mRNA.
