Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.
What is Punnett Square?The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.
Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

Suppose you were interested in the effect of breastfeeding versus formula feeding on the composition of gut flora in newborns. As part of your experiment, stool samples from healthy babies in the study get plated on various agar media. You notice that greater numbers of colonies are recovered when samples are plated on blood agar compared to nutrient agar (NA). After some diligent subculturing, you isolate several bacterial species capable of slow growth on the blood but not on the NA. You correctly surmise that these organisms: ______________
a. are opportunistic blood pathogens.
b. have extensive and complex nutritional requirements not met by NA are inhibited by the ingredients in NA.
c. should be classified as beta-hemolytic.
d. grow because the blood agar suppresses the growth of faster-growing bacteria.

According to the trichromatic theory of color vision, the eye has cones sensitive to colors associated with ___________. A. Red, green, and yellow B. Green, purple, and red C. Red, green, and blue D. Black, brown, and white Please select the best answer from the choices provided A B C D.
The eye has cones sensitive to colors associated with Red, green, and blue
according to the trichromatic theory of color vision.
The trichromatic theory of color vision states that the eyes can view only
three colors which are red, green and blue. This is made through the cones
which are light sensitive pigments in the eyes. The combination of their
wavelengths can be used to create other colors in the visible light spectrum.
The stated facts is the reason why Red, green, and blue is the most
appropriate choice in the list of options.

What are the 3 parts of the digestive system? What does each one do?
Answer:
The Esophagus, Gastric Chamber and Intestines
Explanation:
esophagus pushes chewed food to stomach by peristalsis. The gastric chamber(stomach) works on digesting the food. The digestion completes in the small intestine and goes through the large intestine which absorbs water and minerals. Then it passes through the Anus and get pooped out.
What type of energy is used? Photosynthesis transforms ___________ energy into ___________ energy in ___________ molecules.
Answer:
Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.
Explanation:
During photosynthesis, solar energy is converted into chemical energy in the form of ATP molecules.
----------------------------------------------------------------------------------------------
During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.
ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.
ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.
The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.
These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).
ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.
Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.
Chlorophyll molecules entrap solar energy . There are 2 types of photo systems in chlorophyll. These are photo-system -I and photo-system-II .
The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.
During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.
Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.
The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.
Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.
