9:1:3:3
Answers
Answer:1339
Explanation:
9:3:3:1 is the phenotypic ratio, a phenotypic ratio is a numerical comparison of two phenotypes that demonstrates how frequently the occurrence of one trait corresponds with another.
What is phenotypic ratio?The phenotypic ratio produced from a test cross is used by researchers to determine the gene expression for generations of an organism.
Researchers use the phenotypic ratio obtained from a test cross to determine gene expression for subsequent generations of an organism. A test cross is a genetics method for determining the genotypes and traits of an organism's offspring.
9/16 G-T- --> Green-colored and two-leaved plant
3/16 G-tt ----> Green-colores and three-leaved plant
3/16 ggT---> yellow color and two-leaved plant
1/16 ggtt ---> yellow color and three-leaved plant
Therefore, 9:3:3:1 is the phenotypic ratio, hence option A is correct.

Describe the sun’s role in the sustainability of the Earth’s environment.
Answers
Without the sun, most/all life would cease to exist, especially once depending on light energy from the sun like plants, forming the bases of life.
Explanation:
Plant (producers) use light energy to photosynthesis, producing the energy or food other herbivores (plus, our primary&secondary consumers) dependant upon, to survive; then, they get preyed upon (by our tertiary consumers) - structuring the food chain as we all know of. Hence, sustaining life/ living organisms on earth, for generations to come.
Thus, all life on earth as we know it, basically, won't exist. Abiotic factors are the one's to live a happy ever after. There are non-living, once that don't undergo cellular respiration like us humans, e.g., rocks don't respire.
Anyways the sun is a star, one day (millions to billions years onwards) it's predicted to engulf our earth, when transitioning to become a red giant. So, it might not sustain earth forever.
Don't panic, you won't live to experience this! How fantastic does this sounds?

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
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 hemophiliaThe 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]

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.
