Marina86 [1]

Answer:

The correct answers are:

1. stratospheric ozone depletion

2. climate change

3. desertification/land degradation

4. freshwater decline

5. biodiversity loss.

Explanation:

1) Stratospheric ozone depletion- ozone layer is the protective layer around the earth that protects us from harmful rays such as UV rays coming from the sun. There are depletions or holes in the ozone layer in some parts of Australia and therefore, therefore leading to skin cancer.

2) climatic change - The change in the average temperature or precipitation of an area that takes place due to global warming that changes the earth's climate is changing rapidly.

3) desertification or land degradation - It occurs due to past overuse of fertilizer or barren land that has zero crop yield.

4 )freshwater decline - freshwater is an essential part of the irrigation of crops in agriculture and due to the downfall of groundwater its decline the freshwater produce in these parts.

5) biodiversity loss - Coral reefs are habitats for many aquatic organisms and used as various ways of biodiversity. If there is a loss or decrease in their numbers it will affect and decline the biodiversity of the area.

Explain incomplete dominance, using snapdragon<br> flowers as an example.
oee [108]

Answer:

Dominant allele does not completely conceal recessive allele.

Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.

Explanation:

Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.

For example, in snapdragons:

The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.

However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.

Hope this helped!

In which molecule is most of the energy of glucose stored at the end Of glycosis
fredd [130]
<span>The answer is adenosine triphosphate (ATP). Glycolysis is the metabolic pathway of glucose degradation which products are 2 molecules of pyruvate, 2 molecules of NADH, 2 molecules of ATP, hydrogen ions, and water. The free energy that is released in this process is stored in the form of ATP and NADH. However, the energy stored in ATP is greater than the energy stored in NADH. So, at the end of glycolysis, the most of the energy of glucose is stored in ATP.</span>
