Answer:

Brain, heart, lungs, liver, kidney

Explanation:

Caffeine does not bioaccumulate in our body but heavy metals like mercury and lead can accumulate because caffeine are fat-soluble and broken down into simpler substances and used by the body whereas heavy metals are not fat-soluble and also essential for our body to function normally but when these heavy metals are very in concentration it accumulated in our body and causes several problems in our body organs. These heavy metals accumulation occurs in the organs such as brain, heart, lungs, liver and kidney where it cause problems.

Caffeine is in organic molecules that are metabolized by the liver. Heavy metals are atoms that cannot be broken down. They can be sequestered in the bones or in fatty tissue (with methylmercury) and have a long residence time in the body.

These toxins are stored in the human brain, heart, lungs, liver, and kidney.

The word-heavy metal directs to any metallic chemical element that has a relatively high density and is toxic at low concentrations.

Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), etc.

Thus, Heavy metals are atoms that cannot be broken down.

The reasonable conclusion to draw from the results of the experiment is that DNA is the genetic material.

The experiment conducted by Avery, MacLeod, and McCarty involved transforming nonencapsulated bacteria into encapsulated forms by using extracts from dead encapsulated cells. The results of the three procedures provided important insights.

In Procedure I, both nonencapsulated and encapsulated bacteria grew when the extract made from dead encapsulated cells was added to the culture medium. This indicated that something in the extract was capable of transforming the nonencapsulated bacteria.

In Procedure II, when the extract was treated with protein-degrading enzymes before adding it to the culture medium, both nonencapsulated and encapsulated bacteria still grew. This suggested that proteins were not responsible for the transformation.

However, in Procedure III, when the extract was treated with DNAse before adding it to the culture medium, only nonencapsulated bacteria grew. This result strongly suggested that DNA was the genetic material responsible for the transformation of nonencapsulated bacteria into encapsulated forms.

Based on these results, the reasonable conclusion is that DNA is the genetic material involved in the transformation process. This experiment played a significant role in establishing DNA as the hereditary material, contributing to our understanding of genetics and molecular biology.

The extinction of molluscs or any other invertebrates can represent an irreversible loss of biological diversity due to several reasons, as supported by the reading done for this unit's topic.

Ecological Interactions: Invertebrates play critical roles in various ecological interactions, such as pollination, decomposition, nutrient cycling, and as food sources for other organisms. For example, molluscs such as snails and bivalves play important roles in aquatic ecosystems by filtering water, recycling nutrients, and providing food for other organisms. The loss of these invertebrates can disrupt these ecological interactions, leading to cascading effects on other species and ecosystems.

Genetic Diversity: Invertebrates, including molluscs, exhibit a wide range of genetic diversity within their populations. This genetic diversity provides the raw material for evolutionary processes such as adaptation and speciation, and contributes to the overall resilience and adaptive capacity of ecosystems. The extinction of invertebrate species can result in the loss of unique genetic traits and reduce the genetic diversity of ecosystems, which may have long-term consequences for their ability to adapt to changing environmental conditions.

Ecosystem Services: Invertebrates, including molluscs, provide numerous ecosystem services that are essential for human well-being, such as water purification, pest control, and pollination of crops. The loss of these services due to the extinction of invertebrates can have direct and indirect impacts on human societies, including food production, health, and economic livelihoods.

Conservation Value: Invertebrates, including molluscs, have intrinsic value and contribute to the overall biodiversity of our planet. Each species represents a unique evolutionary history and ecological niche, and their loss can result in a reduction in overall biodiversity. Biodiversity is important for maintaining ecosystem stability, resilience, and functionality, and has aesthetic, cultural, recreational, and educational values.

In conclusion, the extinction of molluscs or any other invertebrates can represent an irreversible loss of biological diversity due to their ecological interactions, genetic diversity, ecosystem services, and conservation value. Protecting and conserving invertebrate species is crucial for maintaining the health and functioning of ecosystems, and for preserving the overall biodiversity of our planet.

Amphibians are more closely related to ray-finned fish than to primates. Image of phylogenetic tree.

Amphibians are ectothermic vertebrates consisting of four members of the class Amphibia. The group Lissamphibia includes all living amphibians. They live in a wide range of habitats, with the majority being terrestrial, burrowing, arboreal or freshwater ecosystems.

Larvae with gills often metamorphose into an adult form that breathes air through the lungs. Amphibians use their skin as a secondary respiratory surface, and some small salamanders and land frogs lack lungs and rely solely on their skin for breathing. They may seem similar to reptiles like lizards, but reptiles, like mammals and birds, are amniotes and do not require water to reproduce.

The speed at which a variable changes over a predetermined amount of time is known as the rate of change.

Your function is changing at the same rate as the change. If your function is a function of position, then the velocity, which denotes how quickly your location is changing, will be the rate of change.

By dividing the difference between two points by the difference between the independent variable, you may calculate the average rate of change without using mathematics. You can use the derivative in calculus to get the current rate of change at any given moment.

Given,

rate = 180 + 6t+0.6t

dp/dt =180+6t+0.6t²

=(300 +61 +0.6t^2)dt

=p(3)-p(0)=180+3t^2+0.6*t^3/3

A person can catch a cold several times in a year because the common cold is caused by a group of viruses known as rhinoviruses.

The person catches measles once in his or her lifetime​ because the person develops resistance to measles virus.

Rhinoviruses mutate rapidly, leading to the development of new strains that can evade the immune system's defenses. As a result, a person can catch a cold from a new strain of the virus, even if they had previously been exposed to another strain.

In contrast, measles is caused by the measles virus, which does not mutate as rapidly as the rhinovirus. Once a person is infected with the measles virus and recovers, their immune system develops immunity to the virus, which provides long-term protection against future infections.
