What do food chains demonstrate? What do they tell us about energy?

Answers

Answer 1

Answer:

Explanation:

They demonstrate the flow of energy from one thing to the next. They tell us Energy is a non-stop force.

Answer 2

Answer:

Food chains demonstrate that energy is ever-lasting. It is always transferred from organism to organism, and the cycle just goes on. Everytime an animal eats another, it absorbs that organisms energy and so on.

1Points

B

C

reduced pesticide and herbicide use


D

unplanned ecosystem interactions

Answers

Answer:

D. a red allele present on at least one of two homologous chromosomes;

D. unplanned ecosystem interactions

Explanation:

A dominant allele or trait would always mask the expression of a recessive trait when both are present in a pair. The only way a recessive trait can express itself is when it is in a homozygous state. Since red color is dominant over white color in the beetle species, the genotype of any red color species would have a red alelle present on at least one of two homologous chromosomes. For example, if red allele is represented by R and white allele is r, the genotype of a red nettle species would be RR or Rr.

In the second question concerning the most reason for concern that some scientists recommends caution be taken regarding genetically modified plants is that in the process of introducing new genes into a population, unforseen and unplanned disruption of the ecosystem may occur as a result of interaction with the ecosystem that these process and it's product may present.

What are the functions of tropical rain forests?

Tropical rainforests are rainforests that occur in areas of tropical rainforest climate in which there is no dry season – all months have an average precipitation of at least 60 mm.

Tropical Rain Forests are found in warm and humid areas with annual precipitation of over 200 cm and mean annual temperature above 22 degrees celsius.

Tropical rainforests are forests with tall trees, warm climates, and lots of rain. In some rainforests it rains more than one inch nearly every day of the year.

a mimic octopus has lost some of its arms, and is in the process of regeneration. Describe a scenario where this ability would provide the octopus an advantage in its environment.

Answers

Answer:A shark tries to eat an octopus they fight but the octopus ends up victorious. The shark only got away with one tentacle,

But fortunately for the octopus it will grow back.

The ability of the octopus arm to regenerate is an advantage in the case of

interaction with larger predators.

The octopus is a marine organism which is characterized by the eight arms.

It uses these structures to find food for its survival. The octopus are eaten by

larger predators such as shark, whale etc.

During the interaction with these large predators, there is a possibility of its

arms being eaten alone instead of its whole body which provides it with the

advantage of survival and regeneration of arms for subsequent finding of

food.

The term genetic drift has been defined as the change in the frequency in the gene variant which has been already existed and in the population the change that takes place is random. There are mainly two types of genetic drift and these are population bottlenecks as well as the second one is the founder effect.

The term hormones means that they are the chemical messengers of the body as they use to travel in the bloodstream to the tissue or the organs. The function of hormones is slow just over the time and they have impact on growth as well as development.

The Adrenal glands are also known as suprarenal glands and they are small in size and they have a triangular shape and they has been located just top of the kidneys.

I NEED YOUR HELP!!! Explain the changes that occur as a tadpole becomes an adult frog or toad.

Answers

Answer:

Sample Response: Tadpoles have fins, gills, and a two-chambered heart, similar to fish. As tadpoles grow up, they develop legs, lungs, and a three-chambered heart. The tail is reduced in size and lost completely as they prepare to leave the water.

Explanation:

During metamorphosis, a tadpole's gills and tail disappear, hind legs develop first, followed by front legs, and lungs replace gills, resulting in an adult frog or toad.

What is Metamorphosis?

Metamorphosis is a biological process that describes the transformation of an animal from one developmental stage to another, such as a tadpole becoming a frog or a caterpillar becoming a butterfly. In frogs, metamorphosis involves a series of changes that occur as the tadpole develops into an adult.

During this process, the tadpole's gills and tail disappear, hind legs develop first, followed by front legs, and lungs replace gills. The skin also thickens and changes, and the digestive system adapts to a new diet. Overall, metamorphosis is a critical part of the life cycle of many animals and allows them to adapt to new environments and ecological niches.

How long does adaptation usually take? (Plant)
1.a decade
2.an hour
3.A few days
4.Centuries

Answers

Answer: The answer is (4), centuries

Explanation:

Plant adaptation is a long-term process that occurs over many generations. It is driven by natural selection, which is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. Hence option D is correct.

The rate of plant adaptation can vary depending on the environment and the plant species. However, it is generally a slow process that takes many years or even centuries to complete.

For example, some plants have adapted to the cold temperatures of the Arctic over millions of years. These plants have developed thick, waxy leaves that help to insulate them from the cold, and they have also developed a slower metabolism that allows them to conserve energy.

Other plants, such as weeds, can adapt to new environments more quickly. This is because weeds are often generalists, meaning that they can survive in a wide range of conditions. They can also reproduce rapidly, which allows them to quickly spread to new areas.

Look at the bean from Days 4-6. Use these data to explain how natural selection changed the number of dark red walking beans over time.

Answers

Answer:

When the volcano erupted, the dark red walking beans were easier to see. Thus, more dark red beans were eaten during days four, five, and six. If the pollution continued, there would be fewer and fewer dark red walking beans over time.

Natural selection changed the number of dark red walking beans over time because, after the volcanic eruption, the dark red beans were clearly visible to predator's eyes; hence, they were picked and eaten by them. As a result, their population decreases.

What is natural selection?

Natural selection is applied to nature where the environment selects animals and plants that it wants to keep, and this is the result behind diversity in the different ecosystems. The availability of resources in nature prevents the desert from having the same diversity as the tropical rain forest. Nature selects the organisms that are best suited to the environment and reproduces to produce future generations.

Here, the dark red beans were not initially visible, but they became readily visible after the volcanic eruption, which let the predator see them and eat them. Slowly, due to this, their population declines, and this happens due to natural selection.

Hence, as the dark red beans are clearly visible to predators' eyes, and their population is declining.

What do you think the pH of water is?

Answers

The pH of pure water is considered to be neutral so it has a pH of 7. However, if you have water that falls below this range, the solutions or substances are considered to be be more acidic than than normal water. On the other hand, if you have water above 7, it is considered alkaline or basic.

In the process of distillation, during condesation the temperature of water decreases Hence absorption of CO2 takes place and some H2CO3 is formed. This is an acid (though very weakly) so water turns acidic. Double distillation enhance this so theoritical pH is 7.0 but practically less than 7.0 (6.2 to 6.8)
