The Comprehensive Environmental Response, Compensation, and Liability Act is primarily put into action by C. Cleaning up massive environmental contamination

Cleaning up severe environmental contamination is the main way to implement Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). It is a federal statute that was implemented to clean up hazardous waste-contaminated areas in the United States and stop further discharges of dangerous substances.

The legislation gives necessary authorities and resources to clean up these hazardous areas, and it holds accountable those who are to blame for the cleaning costs. While these activities may be connected to the cleanup of contaminated sites, CERCLA's principal objectives are not to prevent hazardous material from going into landfills or to evaluate soil and water conservation on private property.

Explanation:

Answer:

The correct answer is - chicks will not be able to survive in water.

Explanation:

Penguins spend the majority of their life in the water and for mating and moult they move to land and also lay their eggs on land. The wings or flippers of the chicks of these penguins are not as efficient as the wings of the adult penguins.

This makes it tough to survive on the waters for the chicks of penguins. Therefore they move to land even they are very clumsy on the land. The mating, molt and raising the chicks to few weeks are the prime reason.

Explanation:

The effect of different coloured light waves on the growth of pea plants was to be observed by a botanist. The same number of seeds were put in three plants with the same type of pots and the same type of soil and every day, they were given the same amount of water. If one pot is placed in a dark windowless closet, the second is placed on the windowsill and the third is placed under a lamp with a green bulb. The variable factor, in this case, will be the colour of light.

Plants require light for the process of photosynthesis. In the process of photosynthesis, the light is trapped by the chlorophyll pigment present in the mesophyll cells of the leaves of the plants.

The light energy is trapped and converted into chemical energy. This is then used for the hydrolysis of water and the reduction of carbon dioxide. These processes then result in the formation of glucose.

Therefore, the plant that gets abundant sunlight on the windowsill will grow better than the plant placed under a lamp and the plant placed under the lamp will grow better than the pot placed in a dark closet.

Answer: chromatophores

Explanation:

The coloration of fishes is due to special cells called chromatophores. Chromatophores are referred to as the cells which produces color. They are seen in animals such as reptiles, fish,amphibians, and crustaceans.

On the other hand, mammals and birds, have a class of cells that is refered to as melanocytes for coloration. The main function of chromatophores is simply for camouflage.

The current composition of the Earth's atmosphere has been around for a relatively short period of time compared to the age of the Earth. The Earth is estimated to be about 4.5 billion years old, and the current composition of the atmosphere is thought to have developed around 2.4 billion years ago.

This means that the current composition of the Earth's atmosphere has been in place for about 53% of the Earth's history. However, it's important to note that the atmosphere has been changing and evolving throughout the Earth's history. The composition of the atmosphere has changed due to various processes such as volcanic eruptions, meteor impacts, and biogenic activity. Also, the atmosphere has been in a state of constant change due to natural processes and human activities. The current composition of the atmosphere is the result of these processes, and it is expected to change in the future as well.

Answer:

B) presence of a nucleus

Presence of a nucleus will be most helpful in classifying a cell as either prokaryotic or eukaryotic. So, the correct option is B.

Prokaryotes are defined as those organisms which possess cells that lack membrane bound organelles. These are usually single cell organisms. Some examples of prokaryotes include bacteria, archaea, and cyanobacteria (blue-green algae).

Eukaryote are defined as those organisms which possess membrane bound organelles. These contain a central nucleus which is surrounded (bound) by a membrane called nuclear envelope. Some examples of eukaryotes include animals, plants, fungi, and protists.

Thus, the presence of a nucleus will be most helpful in classifying a cell as either prokaryotic or eukaryotic. So, the correct option is B.

Hemophilia is a genetic disorder caused by a mutation in the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome.

Females who carry a mutated X chromosome have a 50% chance of passing it on to their offspring. Males who inherit the mutated X chromosome from their mother will have hemophilia, while females who inherit the mutated X chromosome will be carriers of the disorder.

In the case of the Romanov family, it is possible that the female members who carried the mutated X chromosome did not pass it on to their offspring. It is also possible that some of the male members who inherited the mutated X chromosome died before having children, or their children died before being diagnosed with hemophilia. Additionally, it is possible that some of the members of the family were misdiagnosed, or that there were other genetic factors that influenced whether or not someone developed hemophilia.

To determine the efficacy of a treatment targeting acid phosphate, experimental trials assessing its impact on acid phosphate activity or its downstream physiological results would be required.

Maintenance of acid–base balance is fundamental for the normal functioning of biological processes, mainly due to the pH dependence of enzyme function. This article reviews definitions of acid–base balance and describes normal physiology of acid–base metabolism in the extracellular fluid and blood. The individual roles of the kidney, liver, bone, and lungs in maintenance of acid–base balance are outlined in detail in both health and disease. The pathogenesis of common conditions (diabetes, renal failure, drug intoxication) affecting acid–base balance are assessed as well as potential treatment strategies.

Cats have evolved certain behaviors that are influenced by their natural instincts and experiences.

When a cat sees milk, it may be attracted to it because it contains nutrients that are important for its survival, and the cat may associate the presence of milk with positive experiences. This can include nursing from its mother as a kitten or catching and consuming prey that contains milk or milk products.

On the other hand, when a cat sees a stick, it may perceive it as a threat or danger, and may associate it with negative experiences, such as being hit or attacked by a predator. This can trigger the cat's natural instinct to flee or hide from potential danger, as a survival mechanism.

Overall, a cat's behavior is influenced by its instincts, past experiences, and environmental cues. It may approach things that it perceives as positive or beneficial, and avoid or flee from things that it perceives as dangerous or threatening.
