Rutherford did not use aluminum metal in his atomic model experiment.

Atomic model is an explanation of the structure of an atom. It consists of a nucleus, which is made of protons and neutrons, and electrons orbiting the nucleus. The electrons are held in place by electrostatic forces between the nucleus and the electrons. The current accepted atomic model is the quantum mechanical model, which includes the wave-particle duality of matter. The quantum mechanical model provides an accurate description of the behavior of electrons and other subatomic particles.

Instead, he used gold foil in his famous gold foil experiment. This experiment was conducted to study the structure of atoms. He fired alpha particles at the gold foil and observed the scattering of the particles. This experiment allowed him to discover the nucleus of the atom, which was the central part of his atomic model. He also discovered that the atom was mostly empty space. His model was a major breakthrough in the field of atomic physics. It helped scientists to better understand the structure and behavior of atoms.

I know that Diuron caused the coral to bleach​​​ because the coral expelled the algae that are living in their tissues.

This is referred to as a herbicide which is made up of substituted urea and it is used for the control of  crop and noncrop areas. Its mechanism of function is that it is able to inhibit photosynthesis which prevents plant growth.

In a situation where corals bleach, they turn white which is as a result of them expelling algae in their tissues due to different types of stressful conditions. An exposure to chemicals or a high pH may result in this condition also.

In this scenario we were told that the coral bleached however diuron inhibits photosynthesis which could have caused the expulsion of the algae which is why it was chosen.

The hormone responsible for the development of breasts and the accumulation of fat in the hips and thighs during puberty is estrogen.

Estrogen is a group of hormones primarily produced by the ovaries in females. During puberty, the level of estrogen increases, triggering the development of secondary sexual characteristics in girls. One of the primary effects of estrogen is the development of breasts. It stimulates the growth of breast tissue, leading to the formation of mammary glands and the enlargement of the breasts. Estrogen also plays a role in the redistribution of fat in the body. It promotes the accumulation of fat in certain areas, particularly the hips and thighs, which contributes to the development of a more feminine body shape.

As Rachel enters puberty, her body undergoes hormonal changes, and the increase in estrogen levels stimulates breast development and the deposition of fat in her hips and thighs. These changes are part of the normal physiological process of sexual maturation in females. It is important to note that the timing and pace of these developments can vary among individuals, as each person's puberty progresses at a different rate.

Answer: A vacuole undergoes a change in the plant causing wilting and droping.

Explanation:

The vacuole is an organelle, which is a store house of excess water and stored materials. During dehydration, the plant uses water from vacuole. Thus water and stored materials reservoirs get consumed up in this process, the plant experiences scarcity of water. This causes wilting and droping of plant.

The cell membrane is an envelop outside the cells, which causes plants to maintain their structure during stress for example, plant exposed to hypertonic solution. This prevents the cells to burst.

The true statement is: An ecosystem includes both organisms and the physical environment.

This statement accurately describes an ecosystem. An ecosystem refers to a complex network of living organisms (biotic factors) and their physical surroundings (abiotic factors). It encompasses all the interactions between organisms and their environment, including the flow of energy, cycling of nutrients, and various ecological processes.

The other statements are not accurate:

An ecosystem is not usually composed of many biomes identified by dominant vegetation. Instead, ecosystems can exist within a single biome or span across multiple biomes.

A biome is not defined as a transitional boundary between adjacent ecotones. A biome refers to a large-scale community of plants and animals that are adapted to a specific climate and characterized by distinctive vegetation types.

The boundaries between biomes are not always conspicuous. In reality, the transition zones between different biomes can be gradual, with overlapping characteristics and vegetation types, rather than having clear-cut boundaries.

In the Hershey-Chase experiment, the isotope 35S was used to label protein, and the isotope 32P was used to label DNA.The Hershey-Chase experiment was a series of experiments carried out in 1952 by Alfred Hershey and Martha Chase.
These experiments were carried out to determine the nature of the genetic material. In this experiment, the researchers used bacteriophages (viruses that infect bacteria) to investigate whether DNA or protein is the genetic material.Hershey and Chase used radioactive isotopes to label either the protein coat of the virus or the DNA inside it. The bacteriophages were then allowed to infect bacteria, and the researchers observed what happened. They found that when the virus's DNA was labeled with the radioactive isotope 32P, the radioactivity entered the bacteria. On the other hand, when the protein coat was labeled with the radioactive isotope 35S, no radioactivity was detected in the bacteria. This led to the conclusion that DNA is the genetic material that controls the characteristics of an organism.

Answer:

i) Rusting occurs the least in tubes 2 and 3 because either of air and water which are necessary for rusting is absent in the two tubes respectively.

ii) Rusting occurs most in tube 1 because both air and water which are necessary for rusting are present.

Explanation:

Rusting is a chemical change which involves a redox reaction. During the process of rusting, metallic iron is oxidized to hydrated iron (iii) oxide by oxygen present in air.

For rusting to take place effectively, each of these three factors mist be available: metallic iron, oxygen and water.

In the figure above, the iron nails in the three tester tubes will rust to different extents based on the availability of the three factors.

In test tube 1, the iron nails will rust the most because all the three factors: metallic iron, oxygen present in air, and water are abundantly present.

In test tube 2, the iron nails will rust the least or not at all because boiling of water removes dissolved oxygen from water and the oil layer above the boiled water prevents entry of oxygen from air. Thus, the nail do not rust because one of the three factors for rusting to take place, in this instance, oxygen is absent.

In test tube 3, the iron nails rusts the least or not at all as well because moisture or water is absent. Calcium chloride, a drying agent removes all the moisture from inside the tube. Hence, even though air is present, rusting do not occur as there is no moisture or water present.
