Answer:

If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol does, and water moves out of the cell until both solutions are isotonic.

Answer:

Homologous chromosomes separate from each other during anaphase I of meiosis.

Explanation:

Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It involves two rounds of cell division, known as meiosis I and meiosis II, which result in the formation of haploid gametes (sperm or eggs) with half the number of chromosomes as the parent cell.

During meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. Then, during anaphase I, the homologous chromosomes separate from each other and migrate to opposite poles of the cell. This is followed by telophase I, cytokinesis, and the formation of two new cells, each with a haploid set of chromosomes.

In contrast, during meiosis II, the sister chromatids of each chromosome separate from each other and migrate to opposite poles of the cell, resulting in the formation of four haploid daughter cells.

The cell density (cells/mL) = 15× 10^6 cells per mL.

The doubling time of culture = 2 hours

The cell density after 2 hours = 3 x 10^6 cells per mL

Since the dilution did not affect the lag phase and exponential growth rate, the cell density after 10 hours is calculated below:

2 hour = 3 x 10^6 cells per mL

10 hours = X

Cross multiply,

\(x = \frac{10 \times 3 \times10 {}^{6} }{2} \)

\(x = \frac{30 \times 10 {}^{6} }{2} \)

X= 15× 10^6 cells per mL

Therefore, the cell density in (cells/mL) after 10 hours = 15× 10^6 cells per mL.

ATP and NADPH serve as key molecules that connect the light-dependent and light-independent reactions in photosynthesis. They play crucial roles in transferring energy and reducing power between the two processes, ensuring the overall efficiency of photosynthesis.

1. Light-Dependent Reactions: These reactions occur in the thylakoid membranes of the chloroplasts and convert light energy into chemical energy. During this process, light energy is absorbed by chlorophyll and other pigments, leading to the generation of ATP and NADPH.

2. ATP Generation: The absorbed light energy is used to power the electron transport chain, which pumps protons across the thylakoid membrane, creating a proton gradient. The flow of protons back across the membrane through ATP synthase generates ATP from ADP and inorganic phosphate.

3. NADPH Generation: Simultaneously, the energized electrons from the electron transport chain are transferred to NADP+, reducing it to NADPH. This process requires the input of high-energy electrons and protons.

4. Light-Independent Reactions (Calvin Cycle): ATP and NADPH generated during the light-dependent reactions are utilized in the stroma of the chloroplasts to fuel the Calvin cycle. Here, carbon dioxide is fixed and converted into glucose through a series of enzymatic reactions.

5. ATP Utilization: ATP provides the necessary energy to power the various enzyme-catalyzed reactions in the Calvin cycle. It is used to drive the carboxylation of ribulose bisphosphate (RuBP), the regeneration of RuBP, and other key steps in the cycle.

6. NADPH Utilization: NADPH functions as a reducing agent in the Calvin cycle, providing the necessary high-energy electrons to convert carbon dioxide into glucose. It acts as a source of electrons in the reduction of 3-phosphoglycerate to glyceraldehyde 3-phosphate (G3P).

7. Recycling of ADP, NADP+, and Pi: As ATP is hydrolyzed to ADP and inorganic phosphate (Pi) during the Calvin cycle, ADP and Pi are regenerated in the light-dependent reactions. Similarly, NADP+ is regenerated from NADPH.

8. Continuous Cycle: The production of ATP and NADPH in the light-dependent reactions and their utilization in the light-independent reactions create a continuous cycle, ensuring the flow of energy and reducing power required for photosynthesis.

In summary, ATP and NADPH act as energy and reducing power carriers, respectively, connecting the light-dependent reactions that capture light energy with the light-independent reactions that utilize this energy to produce glucose. Their continuous generation and utilization ensure the efficiency and functionality of photosynthesis.

Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.

In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.

Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.

Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms,  annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

Coal is obtained by the process of mining. This process produces acid mine drainage that can seep into watercourses and aquifers, with negative consequences on ecological and human health. Also, if the underground mine tunnels collapse, they cause the land above to subside. This can disrupt the flow of streams and rivers by interfering with natural drainage.

On the other hand, the soil after the creation of a mine is very different from the soil before, being less fertile, which affects not only the flora but also the fauna and the overall biodiverisy of the place, being able to cause even the extinction of some species in that particular place.

Let's denote the width of the park as "w" miles. According to the given information, the length of the park is 1/2 miles and the area of the park is 6/8 square miles.

The area of a rectangle is given by the formula: Area = Length × Width

Given that the length of the park is 1/2 miles and the area of the park is 6/8 square miles, we can set up the following equation:

1/2 * w = 6/8

To solve for "w", we can multiply both sides of the equation by 2 (to eliminate the fraction):

2 * (1/2 * w) = 2 * (6/8)

w = 12/8

Now, we can simplify the fraction w = 12/8:

w = (12 ÷ 4) / (8 ÷ 4)

w = 3/2

So, the width of the park is 3/2 miles.
