Answer:

The formation of a micelle is a response to the amphipathic nature of fatty acids, meaning that they contain both hydrophilic and hydrophobic regions.

Explanation:

Biological membranes remain fluid because of the unsaturated hydrophobic tails, which prevent phospholipid molecules from packing together and forming a solid.

Answer: When two air masses meet together, the boundary between the two is called a weather front. At a front, the two air masses have different densities, based on temperature, and do not easily mix. ... Winds are common at a front. The greater the temperature difference between the two air masses, the stronger the winds will be.

Answer:

B

Explanation:

I believe it is #B because light and energy are what's needed for plants to begin the photosynthesis cycle, which then produces chemical energy which in turn contributes to cellular respiration ect.

I hope this helped :)

The graphic organizer best compares the energy inputs and outputs of cellular respiration and photosynthesis - B. Light energy → photosynthesis → chemical energy → cellular respiration → chemical energy.

Energy transfers from one cellular reaction to another, it changes its form from one type of energy to another. In photosynthesis and cellular respiration energy converts as follows:

Explanation:

Answer:

Explanation:

As you know that the earth has two types of motions,

namely rotation and revolution. Rotation is the

movement of the earth on its axis. The movement of

the earth around the sun in a fixed path or orbit is

called Revolution.

The axis of the earth which is an imaginary line,

makes an angle of 66½° with its orbital plane. The

plane formed by the orbit is known as the orbital plane.

The earth receives light from the sun. Due to the

spherical shape of the earth, only half of it gets light

from the sun at a time (Figure 3.2). The portion facing

the sun experiences day while the other half away from

the sun experiences night. The circle that divides the

day from night on the globe is called the circle of

illumination. This circle does not coincide with the

axis as you see in the Figure 3.2. The earth takes about

24 hours to complete one rotation around its axis.

The period of rotation is known as the earthday. This is

the daily motion of the earth.

Figure 3.3 : Revolution of the Earth and Seasons

What would happen if the earth did not rotate? The

portion of the earth facing the sun would always

experience day, thus bringing continuous warmth to

the region. The other half would remain in darkness

and be freezing cold all the time. Life would not have

been possible in such extreme conditions.

Answer:

greater tubercle

Explanation:

Answer:

Animals are totally dependent on plants. First of all plants produce oxygen which is vital for life on earth. Then, for many animals plants are their basic food, or if plants don’t make up 100 % of their diet, plants are nevertheless essential in their food supply. Plants are also used by animals (and men) as material for building nests (and or homes). Carnivorous animals eat animals which are herbivorous, and without plants they wouldn’t survive, so the carnivors would quickly disappear. Plants are also vital in the maintaining of the climate and without plants the earth’s surface would be subject to erosion. So, to resume, life on earth wouldn’t be possible without plants.

Answer: Passive transport

Explanation: Passive transport does not require energy to move substances across a membrane.

Calcium is very important to the organism, and different factors influence its absorption. Pregnancy, Infancy, Vitamine D increase calcium absorption. Oxalic acid, phytic acids, and being over 70 years old decreases absorption

------------------------------------------

Calcium is a highly significant mineral for the appropriate development and functioning of the organism.

Different factors influence the mineral absorption, favoring it or limiting it.

Among the factors that might favor calcium absorption, we can mention

In the second and third trimesters of pregnancy, calcium absorption is the greatest. The intestinal absorption of calcium in women during this period increases to meet different demands. Calciotropic hormones are involved in the process.

Vitamine D is one of the principal factors involved in calcium regulation. Vitamine D helps to double calcium absorption through the thin intestine.

During infancy, the body is growing, bones are developing, and the body needs to consume a high amount of calcium to accomplish these functions.

Calcium is a baseline mineral to provide children while growing, especially in their first periods of life.

Among the factors that limit calcium absorption, we can mention

Elder people consume less food, and together with food consumption decrease, a less amount of necessary mineral is consumed.

With aging, calcium absorption decreases approximately 20% in the intestine.

Many substances, together with ingested calcium, form compounds that impede mineral absorption through the small intestine.  

So in the presence of substances such as oxalic acid and phytic acid, calcium absorption is limited.

It is recommended not to consume food rich in calcium and food rich in these other substances simultaneously.

Louisiana is losing about 16 square miles/year as a result of coastal erosion. This estimation is a variable as the rate of coastal erosion varies from time to time.

Coastal erosion is the process through which local sea-level rise as a result of intense wave action in coastal sea levels which deteriorate over time along the shore.

In Louisiana, coastal erosion results in the depletion of wetlands via the routes of coastal lines in swamps and marshes. Storms and other natural occurrences that induce erosion impact all coasts. The combination of storm surge at high tidal waves with additional effects from large waves, as well as circumstances often associated with landfalling tropical severe storms, provides the most devastating conditions in landfilled regions.

Therefore, the amount of landmass lost by Louisiana is estimated to be 16 square miles/year as a result of coastal erosion.
