A researcher is studying a cornfield that has been recently abandoned by a farmer. By the end of one year, wild grasses begin to grow in the field. Explain whether this is an example of primary succession or secondary succession. Describe how the researcher can identify when a climax community is reached in the area that was a cornfield.

Answers

Answer 1
I believe it is secondary succession
Answer 2

It is an example of secondary succession.

The community is considered a climax community once it has reached equilibrium, and the environmental conditions and species composition do not change very much.

What is succession?Ecological succession is the process by which the mix of species and habitat in an area changes over time. Gradually, these communities replace one another until a climax community is reached.Example -A dirt field is plowed and left over the summer.

                       -Over the summer, weeds start to grow on the field.

                       - After the weeds grow, small shrubs begin to take root.    

                       - After a few years, trees begin to grow in the field.

Hemophilia is a sex-linked, recessive trait. Which of the following describes the probability of hemophilia in the offspring of a man who does not have hemophilia and a woman whose father is a hemophiliac?
Group of answer choices


Each of their sons will have hemophilia
None of their daughters will have hemophilia
Their sons have a 25% chance of having hemophilia
There is a 50% chance that their daughters will have hemophilia

Answers

Either none or 25%,

If the mother and father don’t have hemophilia, but the grandpa does, it’s a slight chance because it’s not the child’s actual bloodline

None of the daughters from the union will have hemophilia.

Inheritance pattern of hemophilia

The woman would be a carrier since she must have inherited the allele from her father. Thus, her genotype will be [tex]X^HX^h[/tex] assuming the H (h) represents the allele.

The genotype of the father will be [tex]X^HY[/tex]

Crossing the two:          [tex]X^HX^h[/tex]   x    [tex]X^HY[/tex]

                              [tex]X^HX^H[/tex]   [tex]X^HY[/tex]    [tex]X^HX^h[/tex]   [tex]X^hY[/tex]

Thus, none of their daughters will have hemophilia.

how does photosynthesis transforms light energy into stored chemical energy​

Answers

Answer:

The process of photosynthesis converts light energy to stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen.

Explanation:

The process of photosynthesis transforms light energy into stored chemical energy with the help of green-colored pigment in the chloroplast which captures this light radiation and allows it to transform into chemical energy.

What is Photosynthesis?

Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.

The complete reaction of photosynthesis is as follows:

[tex]6CO_2_ + 12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]

After capturing the light radiation from the sun, chlorophyll in the chloroplast significantly converts carbon dioxide plus water into sugars plus released oxygen. This sugar can be further utilized as a source mechanism to derive energy for metabolic activities.

Therefore, the process of photosynthesis efficiently transforms light energy into stored chemical energy.
