John and Joshua used a light microscope to observe a plant cell. They indicated the magnification as x1000. Given the eye piece lens magnification x10. Work out the objective lens magnification.

Answers

Answer:

Objective Lens Magnification = ×100

Explanation:

In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.

In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.

Total Magnification = (eyepiece lens magnification) × (objective lens magnification)

1000 = 10 × obejcetive lens magnification

Dividing both sides by 10

Objective lens magnification = 1000 ÷ 10 = 10

∴ Objective lens magnification = ×100

ANP is a hormone that causes:_________ a. constriction of the afferent arterioles and inhibition of renin release. b. dilation of the afferent arterioles and inhibition of renin release. c. dilation of the afferent arterioles and release of renin. d. constriction of the afferent arterioles and release of renin.

Answers

Answer:

b. dilation of the afferent arterioles and inhibition of renin release.

Explanation:

Atrial Natiuretic Peptide is a hormone which is mainly made and secreted in the atria. It helps in the regulation of blood pressure levels with the use of the kidney through an increase in water and sodium excretion.

The hormone helps in the regulation of blood pressure by ensuring there are dilation of the afferent arterioles to give room for increased flow of blood due to the increased pressure. Study also shows that the enzyme inhibits the release of renin.

TROPHIC CASCADE.

Trophic Cascade occurs when there is a series of significant difference/changes in the population size of organisms in the tropic level of an ecosystem.this change in trophic level occurs in a food chain and as a result of predators being in high trophic levels, they use the opportunity to indirectly promote the population of the organisms in the low trophic levels,they do so by ensuring that species that are at intermediate trophic levels are are in close watch or check.

Answers

Answer:

New leaves appear on a tree in spring. - NO

An amoeba divides in half. - YES

A bean plant produces seeds in long pods. - YES

Pollen grains are released from a flower. - YES

A sea star produces a new arm after losing one to a predator.​ - NO

Explanation:

The appearance of new leaves has nothing to do with reproduction but rather regeneration.

An amoeba dividing in half is a form of reproduction known as asexual. Binary fission is a reproductive process in which an organism divides into two and each half develops into new independent organisms.

A bean plant producing seed is part of the reproductive process. After fertilization, the ovule of a flower becomes the seed. A seed in itself is a ripened fertilized ovule.

The release of pollen grains from the anther of a flower to the stigma of a compatible flower in the same or different individuals plants is known as pollination. Pollination is a reproductive process similar to fertilization.

A sea star producing a new arm after losing one to a predator is a regeneration process rather than a reproductive process.

O mRNA is made in large quantities in infrequent batches.
O mRNA is made in small quantities in frequent batches.

Answers

Answer:

O mRNA is made in small quantities in infrequent batches.

Explanation:

mRNA is made in small quantities in infrequent batches because the affinity of positive transcription is lower and affinity of negative transcription is higher which is responsible for production of mRNA from DNA molecule. Transcription is a process in which the information that is present in DNA molecule is copied to new mRNA molecule. Positive transcription factor is a promoter which promotes the initiation of transcription in order to enable RNA polymerase while negative transcription  factor is a repressor protein.

Over the next century, how do you think the effects of global climate change will compare for species adapted to extreme heat (tropical and hot desert species) versus those adapted to extreme cold (polar species)

Answers

Answer:

If we do not reduce our carbon emissions and instead allow global temperatures to rise by 4.5˚C, up to half the animals and plants in some of the world’s most biodiverse areas could go extinct by 2100, according to a new study. In fact, even if we are able to limit global warming to the Paris climate agreement goal of 2˚ C, areas such as the Amazon and the Galapagos could still lose one quarter of their species, say the researchers, who studied the effects of climate change on 80,000 plants and animals in 35 areas. Another study found that local extinctions (when a species goes extinct in a particular area, but still exists elsewhere) are already occurring in 47 percent of the 976 species studied, in every kind of habitat and climatic zone.

With temperatures rising, precipitation patterns changing, and the weather getting less predictable and more extreme, a 2016 study determined that climate change is already significantly disrupting organisms and ecosystems on land and in water. Animals are not only shifting their range and altering the timing of key life stages— they are also exhibiting differences in their sex ratios, tolerance to heat, and in their bodies. Some of these changes may help a species adapt, while others could speed its demise.

Move, Adapt or Die

Animals can react to climate change in only three ways: They can move, adapt or die.

According to climate change If carbon emission can't reduced and instead allow global temperatures to rise by 4.5˚C, up to half the animals and plants in some of the world’s most biodiverse areas could go extinct by 2100.

What are the effects of climate change?

Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels (like coal, oil, and gas) which produces heat-trapping gases.

More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.

The potential future effects of global climate change include more frequent wildfires, longer periods of drought in some regions, and an increase in the duration and intensity of tropical storms.

What is the impact of climate change?

Climate change is the pattern of the disturbance in the weather and the temperature condition of the earth and its various places. It is a result of increased global warming caused by pollution.

Climate change affects the oceans and sea by raising their temperature leading to the melting of the ice caps and glaciers. This results in habitat destruction and decreases the population of arctic animals like polar bears.

To increase the population of polar bears, humans can breed them in an artificial environment and then can release them into their natural habitat like the colder places.

The scientists' work would still be considered a success because new ideas often develop from unsuccessful experimentation. Many of today's famous inventions and celebrities failed at the start of their career. However, because they did not give up on their goal, they eventually succeeded. A few examples of those people are Bill Gates, Albert Einstein, and Michael Jordan.

Here is an influential quote, said by Michael Jordan, that I think accurately supports this topic of discussion:

"I've missed more than 9,000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game-winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed."
