both ethanol and glycine are small molecules of approximately equal molecular weight. However, ethanol is much more membrane permeable than glycine. What accounts for the large difference in membrane permeability between ethanol and glycine

Answers

Answer:

Ethanol is a non polar molecule.Therefore it passes through the cells membrane easily by diffusion like other non polar like CO2 and water.However, glycine is an amino acid ( the simplest amino acid) a charged molecule /polar molecule/.it can not therefore pass through the bilayer by simple diffusion because of the phospholipid bi-layers. Therefore special transport proteins are needed for its passage across the cell membrane.

Example-GLYT 1 and 2 are the carrier proteins  specific for glycine transport across the membrane.

Which eras ended with a mass extinction?
O A. Paleozoic and Precambrian
O B. Mesozoic and Paleozoic
OC. Mesozoic and Cenozoic
O D. Cenozoic and Paleozoic

Answers

B. Mesozoic and Paleozoic eras ended with mass extinctions.

What is Mass extinctions?

Mass extinctions are periods in Earth's history when a significant proportion of the planet's biodiversity is wiped out in a relatively short period of time.

These events have occurred several times throughout Earth's history, and they are typically associated with major geological and environmental changes.

The Mesozoic era, which lasted from about 252 to 66 million years ago, ended with the Cretaceous-Paleogene extinction event. This event was likely caused by the impact of a large asteroid or comet, which triggered a range of environmental changes, including wildfires, acid rain, and a nuclear winter-like effect.

The event is most famous for wiping out the dinosaurs, but it also resulted in the extinction of many other species, both on land and in the oceans.

The Mesozoic era ended with the Cretaceous-Paleogene extinction event, which wiped out the dinosaurs and many other species.

The Paleozoic era ended with the Permian-Triassic extinction event, which was the largest mass extinction in Earth's history, and resulted in the loss of approximately 96% of all marine species and 70% of land species.

Answers

Answer:demand for resources such as fossil fuels

Explanation:

Building large manufacturing facilities can affect ecosystems by increasing the demand for resources such as fossil fuels.

Thus, The breakdown of buried, carbon-based organisms that perished millions of years ago produces fossil fuels. They produce deposits rich in carbon, which are taken out and burned to provide energy.

They presently provide about 80% of the world's energy and are non-renewable. A vast array of items, including plastic and steel, are also produced using them. Coal, oil, and gas are the three forms of fossil fuels.

Global warming is mostly caused by emissions from fossil fuels, according to the Intergovernmental Panel on Climate Change (IPCC). 89% of the world's CO2 emissions in 2018 came from industry and fossil fuels.

Thus, Building large manufacturing facilities can affect ecosystems by increasing the demand for resources such as fossil fuels.

The diffusion spot diameter with one crystal at 15 min ( mm) is 59 . The rate of diffusion with one crystal So how would I convert this 59 to ( mm/h)?

Answers

Answer:

This is straight forward.If  there are 60 minutes in one hour, then to convert minutes to hours as requested, simply divide the number of minutes given by  60.Thus if you divided the 59 by 60 it gives you what?round the answer to whole number.

When there is a moment of any solute present in the solution from high concentration to low concentration area is called diffusion.

It will take 0.25 hours to diffuse one crystal.

This can be calculated by:

Given,

Time for one crystal diffusion = 15 min

Diameter for one crystal diffusion  = 59 mm

In 1 hour there are 60 minutes.

60 minutes = 1 hour.

Then 15 minutes = ? hours

[tex]\dfrac{15 \; \text{minutes}}{60 \; \text{minutes}} = 0.25[/tex]

Suppose Stephen breeds snakes and wants to optimize production of offspring with both black bodies and brown eyes, which are coded for by two genes with the recessive alleles b and e, respectively. In snakes, B codes for brown bodies and E codes for red eyes. Stephen crosses two heterozygotes that produce 544 offspring. How many of these 544 offspring are predicted to have both black bodies and brown eyes?

Answers

Answer:

34

Explanation:

B codes for brown bodies.

E codes of red eyes.

b and e together code for black bodies and brown eyes.

Heterozygous brown body snake would have the genotype Bb.

Heterozygous red eyes would have the genotype Ee.

Individuals that are heteozygous for both trait would have the genotype BbEe.

Crossing two heterozygous individuals:

BbEe   x   BbEe

Progeny:

9 BBEE

3 B_ee

3 bbE_

1 bbee

Recall that black bodies and brown eyes requires be, hence the ratio of the progeny with black bodies and brown eyes is 1/16.

If the total number of offspring produced is 544, the number predicted to have black bodes and brown eyes would be:

    1/16 x 544 = 34

Answers

Answer:

The correct answer is option A, that is, light intensity and direction.

Explanation:

A photoreceptive organelle witnessed in the motile or flagellated cells of unicellular photosynthetic species like euglenoids and green algae is known as the stigma or the eyespot apparatus. It permits the cells of the organism to detect the intensity and direction of the light and react towards it.  

This assists the organisms to either swim away from the light known as negative phototaxis, or to swim towards it known as positive phototaxis. The eyespots are the basic and the most typical eyes witnessed in nature. The eyespots comprise bright areas or orange and red granules of pigment and photoreceptors.
