The movement by diffusion of charged ions such as Na+ and Cl- across the plasma membrane is blocked by the lipid bilayer in the middle of the plasma membrane. true of false?
Answer:
True.
Explanation:
As we know, the plasma membrane of the cells is semi-impermeable, that is, it only allows the passage of some molecules in sizes and specific burning nature. Although the Na + and Cl- molecules are very small, they are polar, electrically charged molecules. These molecules are not well seen by the membrane, which does not allow them to pass into the intracellular medium.

Investigator Murray is examining evidence from an old crime scene. She has a blood sample, but she believes that the sample may be too degraded to get DNA from. Investigator Murray decides to try to retrieve mtDNA from the sample and compare it to a sample from her suspect. What information could this sample give her?
A The blood at the crime scene belonged to her suspect.
B The suspect has blond hair and blue eyes.
C There is a maternal relation between the two people.
D The person from the crime scene has been near the suspect.
The answer is C.
Explanation:
They explained that "Investigator Murray decides to try to retrieve mtDNA from the sample and compare it to a sample from her suspect. What information could this sample give her?"
mtDNA: Mitochondrial DNA (mtDNA) can also be useful to investigators and is found in the energy-producing organelles called mitochondria. This type of DNA can sometimes be recovered from evidence that is too degraded or old to yield regular DNA. Although mtDNA can't be linked to one individual, it can show that subjects are maternally related, since it is passed down through the maternal side of the family.
Note to you:I took the test and the definition of mtDNA (also known as Mitochondrial DNA) came from my notes. Have a good one and I hope it helps!! :)
What is an important factor that could make a renewable energy source a realistic alternative to nonrenewable energy sources?
A. Stop the use of low-carbon, low-energy yield brown coal in power plants, and switch over to more efficient high-carbon, high-energy yield hard coal.
B. Continue to mine coal at current rates, but use the coal to create new types of photovoltaic cells for use in solar panels on large solar farms.
C. Decrease the cost of building wind turbines to decrease the initial cost of wind energy so that it is closer to the cost of energy currently produced from burning coal.
D. Increase the volume of natural gas extracted from wells through hydraulic fracturing to decrease the amount of coal that has to be mined for combustion.
Answer:
C.
Explanation:
Renewable energy sources (e.g., solar energy, wind energy, hydrothermal energy) represent the most important alternative to reduce global warming effects due to the use of fossil fuels. However, the use of renewable energy sources is nowadays more expensive than those derived from fossil fuels. For example, it has been calculated that solar energy costs around 20 cents more per KWH than coal or gas. Wind energy is even more expensive than solar energy. In consequence, it is expected that in the near future renewable energy production costs decrease in order to make this type of energy source cheaper than fossil fuels.

PLEASE Answer each question correctly.
Answer:
Explanation:
1 . 3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.
3 .Infiltration is the process by which water on the ground surface enters the soil. Infiltration is governed by two forces, gravity, and capillary action. While smaller pores offer greater resistance to gravity, very small pores pull water through capillary action in addition to and even against the force of gravity.
4.Water is removed from the surface of the Earth to the atmosphere by two distinct mechanisms: evaporation and transpiration. Evaporation can be defined as the process where liquid water is transformed into a gaseous state. Transpiration is the process of water loss from plants through stomata.
5.Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

The answer is below
Explanation:
The possible phenotypes of the mother can be any of the following
AA - A phenotype
AB - AB phenotype (here the mother must have contributed an A gene for it to be possible)
AO - A phenotype (here the mother may have contributed any of the A or O gene.)
BO - B phenotype (here, the mother would only need to contribute O gene for this to be possible)

A.natural selection
B.genetic variation
C.pollution
Answer: Genetic variation
Explanation: It could lead to natural selection, but natural selection isn't the cause. Many years down the road you could see a particular variation having a higher population, which is the result of natural selection/survival of the fittest via better camouflaging from predators.

The gravity of the Sun and Moon pulls earth's surface in opposite directions:
Answer:
The Moon's gravity pulls more on the planet than the water on the opposite side. These two water bulges on opposite sides of the Earth aligned with the Moon are the high tides. Spring tides occur when the Earth, the Sun, and the Moon are aligned, increasing the gravitational pull on the oceans.
The direction of gravitational pull of the sun and Moon on the earth surface occurs in the same and opposite directions depending on the time of the day.
Hello your question its quite vague but a general answer is provided above
The gravity of the Sun pulls the Earth towards itself while the gravity of the moon on the earth is strongest at side facing the moon.
The direction of gravitational pull of the sun and Moon on the earth surface occurs in the same and opposite directions. and this depends on the time of the day. at night when the moon is in-between the earth and the sun the direction of the gravitational pull is strongest on the side of the earth facing the moon which is in the same direction with the gravitational pull of the sun towards the earth.
while during the day the direction of the gravitational pull of the moon on the earth is strongest on the side of the earth facing the moon which is in opposite direction to the gravitational pull of the sun on the earth.
Hence we can conclude that The direction of gravitational pull of the sun and Moon on the earth surface occurs in the same and opposite directions depending on the time of the day.

The wing of a bird and the front limb of a mammal have a similar number and arrangement of bones. Which evolutionary relationship explains these similarities? A. The wing and front limb are homologous structures; each evolved from a common ancestor. B. The wing and front limb are analogous structures; each evolved from a common ancestor. C. The wing and front limb are analogous structures; each evolved independently. D. The wing and front limb are vestigial structures; one evolved from the other.
Answer:
A
Explanation:
The correct answer would be that the wing and front limb are homologous structures; each evolved from a common ancestor.
Homologous structures are organs of different organisms that look similar in structure but perform different functions on their respective owners. They are as opposed to analogous organs which look different on different organisms but perform similar functions on them.
An example of the homologous organ is the wing of birds and the fore-limbs of mammals which are both built on a five-digit plant, also known as pentadactyl plan. While birds use their wings to fly, the fore-limbs of mammals are adapted for grasping or walking. An example of the analogous organ is the wing of birds and the wing of insects. They both look structurally different but are both for flying.
The correct option is A.
This picture below shows the fossil of three species of mosasuar, large marine reptiles that are now extinct what do similarities in these mosasaur indicate
The similarities in the fossil fuels of the given species of the mosasaur indicates a close relationship between the organisms.
The fossil records of the extinct organisms are used for studying the characteristics of their genome and it also helps to understand the similarities and differences between the different species of the same organism which have become extinct.
Several fossil records of thousands of organisms have been recovered and studied by the paleontologists till date. The study of these fossils have suggested that the organisms that have become extinct were very different from the organisms that are found to be present today.
