Answer

Potable water is available in almost all populated areas of the Earth, although it may be expensive and the supply may not always be sustainable. Sources where water may be obtained include: Ground sources such as groundwater, springs, hyporheic zones and aquifers.

Our drinking water comes from lakes, rivers and groundwater. For most Americans, the water then flows from intake points to a treatment plant, a storage tank, and then to our houses through various pipe systems. A typical water treatment process. Coagulation and flocculation - Chemicals are added to the water.
hope this helped i didnt know the exact answer but have a wonderful day :)

If you walk through a busy crowd and feel a few different people bump and push past you as they walk by, which skin receptors wo
Likurg_2 [28]

Answer:

Mechanoreceptors would be activated

Explanation:

The skin is a complex organ that is found covering the entire surface of the human body. The mechanoreceptors are responsible for the sense of touch, that is, the capture of pressure on the skin. They are the Meissner corpuscles and the Vater-Pacini corpuscles, which are made up of nerve endings and connective tissue, in other words, they are receptors that are stimulated by muscle contraction and pressure on the joint elements. It allows to know the position of the body and the degree of contraction of the muscles.

Compared the Mendelian Dominance, how to incomplete dominance and codominance increase the number of phenotypes? Provide an exam
REY [17]

Answer/Explanation:

<h3>Incomplete dominance</h3>

In incomplete dominance, one allele is not entirely dominant over the other, so heterozygotes (organisms with two different alleles for the gene) show an intermediate or blended phenotype.

For example, consider flower colour.

  • If the allele for red flowers (R) was dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, and rr) and two possible phenotypes. (Red (RR and Rr) and white (rr)).
  • However, if the allele for red flowers (R) was incompletely dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, rr), and three possible phenotypes (red (RR), white (rr), and pink (Rr))
<h3>Co-dominance</h3>

In incomplete dominance, two alleles are both expressed, one is not dominant over the other. Therefore, heterozygotes (organisms with two different alleles for the gene) express both traits.

For example, consider flower patterns.

  • If the allele for spots (F) was dominant over the allele for stripes (f), then there are three possible genotypes (FF, Ff, and ff) and two possible phenotypes. (Spots (Ff and ff) and stripes (ff)).
  • However, if the allele for spots (F) was co-dominant to the allele for stripes (f), then there are three possible genotypes (FF, Ff, ff), and three possible phenotypes (spots (FF), stripes (ff), and spots and stripes (Ff))

The effects of deforestation include: increased soil fertility, as without trees to absorb them, the essential mineral nutrients
Nitella [24]

Answer:

Harm to downstream fisheries, due to sedimentation of waterways from increased soil erosion.

Explanation:

Deforestation is the reduction of forest area in a given territory, both because of nature or man-made causes.  It results in the loss of habitats for many animal and plant species, the destruction of natural peoples' habitats and livelihoods, and increases soil erosion and large floods in valleys. Often, a previously forested area becomes waste land.

the graph shows how the rate of photosynthesis of a plant varies with light intensity. interpret the graph and justify statement
dezoksy [38]

The graph shows that the rate of photosynthesis increases with increased light intensity, other conditions being constant.

<h3>Photosynthesis and light intensity</h3>

From the graph, the rate of photosynthesis increases with an increase in light intensity.

At low light intensity, the photosynthesis rate increases with an increase in the concentration of carbon dioxide and level off at some point.

With medium light intensity, the rate of photosynthesis is about twice that of low light intensity under the same concentration of carbon dioxide. It also gradually levels off when the concentration of carbon dioxide reached a particular point.

The same trend applies to high light intensity. The rate of photosynthesis increased accordingly, much more than low and medium-intensity light.

Both light and carbon dioxide concentration can limit the rate of photosynthesis. When both factors are abundant, photosynthesis can be limited by other factors such as water, nutrient, etc.

10. The evolution of Darwin's finches is an example of a. equilibrium. c. stabilizing selection. b. speciation. d. artificial se
lesantik [10]

Answer:

B) speciation.

Explanation:

The Galapagos island is known for the different varieties of finches (species of birds) which could be distinguished on the basis of different beak shapes and size.

This is the result of the selection pressure which led to the divergence of the species on the island through a mechanism called adaptive radiation.

Since the adaptive radiation leads to the formation of different species on the same island, the process of formation species is known as the speciation.

Thus, speciation is the correct answer.
