Humanity faces a great number of environmental challenges, including: resource depletion, ecosystem service deterioration, pollution, biodiversity loss and climate change. Technology and research have both had positive and negative effects on the environment. Evaluate the impact of scientific research and technology on the environment. What are some ways that scientific research has harmed the environment. Choose ALL that apply. A) Research has led to the depletion of natural resources. Eliminate B) Air, water, heat and noise pollution can all be caused by producing and using technology. C) Scientific research has led to widespread increases in carbon emissions which has led to global climate change. D) Scientific research has caused widespread habitat disturbance and destruction as scientists have invaded ecosystems. E) Manufacturing technology creates large amounts of waste, and used computers and electronics get thrown out when they break or become outdated.

Answers

Answer:

Option B and E and D

Explanation:

Technological advancement has led to growth of industries and manufacturing units and hence the net production of goods. This has led to the use of natural resources and release of pollution of all forms. Environmental research leads to intrusion into niche habitats and hence causes its destruction.

Option B, D and E are correct

Scientists are studying the mating habits of a population of butterfly fish on a Caribbean coral reef. They discover that both the largest and smallest males get the most mates and pass on the largest number of genes to the population's offspring. The largest males get a large number of mates because they can guard the females, preventing most of the smaller males from mating. However, the very smallest males also get a large number of mates because they escape the notice of the larger males and are able to mate with the females quickly. Based on these observations, which selective force appears to be acting on male body size in this population?

Answers

Answer:

The correct answer is - Disruptive selection.

Explanation:

Disruptive selection is a mode of natural selection that exhibits that two extreme values of phenotypic traits of the population are favored by this population than the population with their intermediate values. Disruptive selection occurs when there is a fitness advantage of extreme values of phenotypic traits over more intermediate phenotypes.

In this case, the largest males mates more, due to fact that they can guard the females, than smaller males. The smallest fishes also get a high number of mates as are able to mate with the females quickly without coming to the notice of larger males.

how is classification of animal related to its adaptational features​

Answers

Answer:

it is important because it helps us identify and name all the animals on earth

Answer:

We can classify organisms on the basis of its physical features.

Explanation:

Classification of animal is related to its adaptational features​ because adaptational features​ of an organism provides information about the organism to which specific kingdom or phylum the organism belongs. These adaptational features​ are gained by the organisms due to different environmental as well as climatic conditions the organism have which make changes in the body features of an organism. So we can classify organisms on the basis of its physical features.

A construction company wants to trap pollutants in runoff at its sites. What should the company do?
O A.
Practice conservation tillage at the sites.
O B. Release beneficial insects,
such as spiders and ladybugs, at the sites.
O C. Plant grass and
lay straw at the sites.
O D. Plant trees at the sites.

Answers

Answer:

O C. Plant grass and  lay straw at the sites.

Explanation:

Plant grass and  lay straw at the sites are used by the company to trap pollutants at its sites because these plants reduce the runoff by absorbing most of the water and by absorbing water we can trap the pollutants present in that water. By trapping this industrial water, we can reduce water pollution that occurs due to this industrial waste and pollutants so planting grass and lay straw is the best way to trap pollutant.

Answers

Answer:

yea

Explanation:

cause our climate conditions changes everyday depends on the atmosphere at that time so if there fire in a forest all the animals there have to adapt to the smoke.

Yes, if the environmental conditions in an area changes that the plants and animals that inhabit that region will change their features to adapt to the changing conditions.

Why plants and animals will change their features?

Plants and animals are fundamentally different in many ways, but one of the most obvious is in how they deal with temperature.The climatic niche of a species reflects where it can live.A species with a wide climatic niche can range widely across many different conditions and may be especially resilient to climate change.Different sets of plant and animal species tend to occur at different elevations, which differ in temperature and precipitation.

Onion root tips are often used to study mitosis because they grow very rapidly, which means that many cells are dividing. The very tip of the onion root ends in a structure called the root cap. The other end of the root attaches to the onion. A scientist is interested in determining whether an onion root tip grows from the base of the root or from the tip near the root cap. She counts the number of cells that are in one of the phases of mitosis at different distances from the root cap. What is the dependent variable in her experiment

Answers

Answer:

- Dependent variable: number of cells that are in one of the phases of mitosis

Explanation:

In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.
