When excess fertilizer is placed around the root of a tomato plant, the tonicity of the solution that the plant cells are bathed in is affected. If the fertilizer solution is hypertonic, the plant cells will lose water through osmosis, causing the leaves to shrivel and turn brown. If the fertilizer solution is hypotonic, water enters the plant cells, causing them to become stiff and turgid.

When excess fertilizer is placed around the root of a tomato plant, the tonicity of the solution that the plant cells are bathed in is affected. If the fertilizer solution is hypertonic, the plant cells will lose water through osmosis, causing the leaves to shrivel and turn brown. This is because the water leaves the plant cells, leading to a loss of turgor pressure needed to keep the leaves and stems upright. On the other hand, if the fertilizer solution is hypotonic, water enters the plant cells, resulting in higher osmotic pressure and turgor pressure, causing the cells to become stiff and turgid.

The Mitochondria gets it energy from food. While the chloroplast get there food from the suns energy through the process of photosynthesis. Chloroplast are also what make the plant leaves green.

Answer: The correct answer is -

Mitochondria produce energy from food, while chloroplasts produce food from the Sun’s energy.

Mitochondria is a specialised membrane bound organelle that is present in the eukaryotes (such as plant and animals) and it is considered as the power house of the cells. It helps in the generation of large amount of energy in the form of ATP (adenosine triphosphate) through cellular respiration (that depicts complete oxidation of food, such as glucose).

Chloroplast is a membrane bound organelle, which is present in the photosynthetic organsisms such as green plants and algae. It is the site for photosynthesis, which is a process of formation of food using sunlight in the presence of carbon dioxide and water.

Thus, second option is the right answer.

The population of predators will increase first and then decrease slowly.

Answer:

The answer is Osmosis is specific to molecule movement and does not require energy.

Explanation:

Osmosis a type of passive diffusion wherein substances pass through the semi-permeable cell bilayer and relies on the concentration gradient of a specific molecule. This usually involves water, carbon dioxide, and oxygen and they move from high to low concentrations or electrochemical gradient.

To demonstrate, a glass with water plus sugar is placed inside with a semi-permeable membrane in between. The solute (sugar) will not pass through as it's too big for the membrane so the solvent (water) will be the one that will cross the membrane, from high to low concentrations.

The correct statement is that osmosis is a type of diffusion and is specific to water. While both osmosis and diffusion are passive processes that do not require energy, diffusion is not limited to water molecules and osmosis is a method of water molecules' movement.

The correct statement is that osmosis is a type of diffusion and is specific to water. Osmosis is the passive movement of water molecules, across a semi-permeable membrane, from an area of lower solute concentration to an area of higher solute concentration. Diffusion, on the other hand, is the movement of molecules from an area of higher concentration to an area of lower concentration, until the concentrations are equal in all areas, and it doesn't necessarily require energy.

While both osmosis and diffusion are passive processes that do not require energy, they are not limited to specific types of molecules. Diffusion can occur with any molecules, including solids, liquids, and gases, as long as there's a concentration gradient. Osmosis, while it is a type of diffusion, is specific to the movement of water molecules.

Ans. 'The chemical energy stored in the glucose molecule is available to do work.'

Glucose molecule is considered as primary fuel of the body as it provides energy for all cellular activities.

All organisms generate energy by breakdown of glucose molecules through the process of cellular respiration, in which chemical energy of glucose is converted ATP molecules. The ATP molecules release energy during hydrolysis and provide energy to do work. Hence, glucose can be used as an example of potential energy.

The liver is primarily located in the right upper quadrant of the abdominopelvic cavity, mainly within the right hypochondriac region and extending into the epigastric region.

The liver is a vital organ located in the upper right part of the abdomen, primarily falling within the right upper quadrant of the abdominopelvic quadrants. It is situated just below the diaphragm, to the right of the stomach, and is protected by the surrounding ribs.

When considering the nine abdominopelvic regions, the liver is primarily in the right hypochondriac region, but it also extends into the epigastric region due to its size and the presence of multiple lobes. The location of the liver is significant for healthcare providers to communicate clearly about abdominal issues, such as the location of pain or the presence of masses.

The correct answer is (d) A large central vacuole.

Plant cell has very large central vacuole that helps in maintaining the turgor pressure of the cell and it also helps in maintaining the stability of plant cell. The maximum amount of water is absorbed in the vacuole and helps to keep the cell erect. In mature plants the vacuole tend to very large and provides mechanical support to the cell. It also helps in waste disposal, protection, growth and storage of plant materials.

Mendel's contribution to genetics was the discovery of alleles which are the different forms of a gene present in an organism and how these genes are transferred from parents to offspring. Thus, the given statement is false.

Mendel did his experimental work on the garden pea plants (Pisum sativum). He discovered the laws of inheritance. He observed that genes are present in pairs and are inherited as distinct units and one gene is transferred from each parent. He called alleles as dominant and recessive. Dominant alleles show their presence in each generation whereas recessive traits are found to skip generations.

Mendel observed the segregation of genes in a monohybrid cross and the appearance in the offspring as dominant or recessive traits in different generations. He also gave the law of independent assortment of characters where he told that characters are inherited independent of each other in all the generations.

The environment plays a pivotal role in evolution by natural selection by determining which traits are advantageous and promoting survival and reproduction of organisms with these traits, thus leading to a diversity of species.

The environment has a crucial role in the theory of evolution by natural selection. Firstly, the environment poses challenges and pressures, such as availability of resources and changing conditions, leading to a struggle for survival known as the 'survival of the fittest'. Organisms with advantageous traits or characteristics, better suited to their environment, have a better chance of surviving and reproducing, passing on these advantageous genes to their offspring.

On the other hand, the environment can also vary and change, meaning what were once considered unfavorable traits can become favorable in the new environment. As such, organisms' genotype and phenotype interact with their environment, and those with the most favorable traits will survive and reproduce more.

Therefore, the environment plays an influential role in the entire process, determining which traits are advantageous and leading to a biodiversity of species through the mechanism of natural selection.

Explanation why dipping a cleaning brush into the cleaning solution container when cleaning a firearm should be avoided.

When cleaning your firearm, you should avoid dipping a cleaning brush directly into the cleaning solution container because it can contaminate the entire solution with residue from the firearm.

This contamination can potentially affect the cleaning efficiency and even damage the firearm during the cleaning process.

The human body is composed of eukaryotic cells, which have a membrane-bound nucleus and differ from the prokaryotic cells of single-celled organisms like bacteria and archaea.

The human body is composed of eukaryotic cells. This places us in the company of animals, plants, fungi, and protists—all of which are also composed of eukaryotic cells. Eukaryotic cells are characterized by having a nucleus that is bound by a membrane, as well as other membrane-bound organelles. In contrast to eukaryotic cells, prokaryotic cells—such as those belonging to the domains Bacteria and Archaea—are generally single-celled organisms without a nucleus.

Biologists differentiate cells into these two categories based on structural and genetic differences. This distinction is important for understanding the complexity of multicellular organisms like ourselves, and also helps in studying the diverse forms of life on Earth. The discovery of the three domains of life (Bacteria, Archaea, and Eukarya) was a significant development in the field of biology, revealing that prokaryotes are more nuanced and diverse than previously thought.

Explanation:

The nurse must familiarize the client with risk of mastitis development after childbirth. The education should involve possible situations such as the use of only one nipple for breastfeeding, use of tight-fitting bra, and extreme fatigue and tiredness which must be avoided during postpartum.

Further explanation:

The condition is seen in women during which the breast becomes inflamed and swollen is called mastitis. It occurs in those women who have recently given birth and breastfeed. During this condition, the breast ducts are infected. The further progression of mastitis results in breast abscess which causes formation of pus in the breast tissue.  

The occurrence of mastitis can be seen both in the presence or absence of an infection. When the milk accumulates inside the tissues of the breast it is called milk stasis. This occurs without any infection but the progression of inflammation is followed by infection as stagnant milk is prone to bacterial growth. When mastitis occurs in the presence of infection, it usually occurs due to the broken nipple. The broken area provides a passage for the bacteria to enter and infect the tissues and result in inflammation.

The symptoms of mastitis include enlarged or swollen breast, itching, redness, or warmth sensation on the breast, cut or break in the skin or nipple of the breast. Mastitis can be treated by providing antibiotics against bacterial infection or drug-like ibuprofen can be used to reduce the pain, swelling, and fever.

A postpartum client is more liable to get mastitis and therefore a nurse must educate her about the preventive measure. The measures include breastfeeding frequently, take care of the nipple to prevent any breaks, the use of proper feeding techniques, equal use of both the breasts for feeding and stopping breastfeeding gradually over several weeks while accustoming the infant to other food simultaneously.
