The word photosynthesis can be broken down into the words photo and synthesis. What do both words mean by themselves, and how ca

NeTakaya

Plants absorb sunlight and turn that energy into food; the process is known as photosynthesis. This is a compound word made up of photo (which means "light") and synthesis (which means "to put together").

Select all that apply. Which vertebrates are endothermic?

ololo11 [35]

Vertebrates that are endothermic are birds and mammals. Endothermic organisms are able to regulate their own body temperature while ectothermic organisms depend on the temperature of the environment. Birds and mammals are endothermic organisms. Fish, amphibians, and reptiles are ectothermic organisms.

Brut [27]

Answer:

The generation of nitric oxide is done by almost every kind of cell present in the human body, it is one of the essential constituents that plays an important function in maintaining proper health of blood vessels. The nitric oxide acts as a vasodilator, that is, it relaxes the blood vessels' inner muscles, thus making the blood vessels to broaden.

Therefore it can be concluded that nitric oxide enhances the flow of blood and thus reduces the blood pressure. In this manner, nitric oxide helps in tackling the symptoms of conditions like angina.

At the molecular level. the activation of guanylyl cyclase is done by nitric oxide, which further catalyzes the production of cGMP. This cGMP further functions as an intracellular messenger in a pathway that results in the relaxation of the smooth muscles.

How do you do dihybrid genetic problems

svet-max [94.6K]

Dihybrid CrossProblem 3: A genetic cross yielding a 9:3:3:1 ratio of offspring.Tutorial to help answer the questionWhich of the following genetic crosses would be predicted to give a phenotypic ratio of 9:3:3:1?TutorialPredicting the genotype of offspringDetermine all possible combinations of alleles in the gametes for each parent.Half of the gametes get a dominant S and a dominant Y allele; the other half of the gametes get a recessive s and a recessive y allele.Both parents produce 25% each of SY, Sy, sY, and sy.(Review the tutorials for problems #1 and problem #4 if necessary).Punnett square.

Since each Parent produces 4 different combinations of alleles in the gametes, draw a 4 square by 4 square punnett square.

Gametes from Parent 1

List the gametes for Parent 1 along one edge of the punnett square.

Gametes from Parent 2

List the gametes for Parent 2 along one edge of the punnett square.

Alleles from Parent 1

Fill out the squares with the alleles of Parent 1.

Alleles from Parent 2Fill out the squares with the alleles from Parent 2.The result is the prediction of all possible combinations of genotypes for the offspring of the dihybrid cross, SsYy x SsYy.

Predicting the phenotype of offspring
Spherical, yellow phenotypeThere are 9 genotypes for spherical, yellow seeded plants. They are:SSYY (1/16)
SSYy (2/16)
SsYY (2/16)
SsYy (4/16)Spherical, green phenotypeTwo recessive alleles result in green seeded plants.There are 2 genotypes for spherical, green seeded plants. They are:SSyy (1/16)
Ssyy (2/16)Dented, yellow phenotypeTwo recessive s alleles result in dented seeded plants.There are 2 genotypes for dented, yellow seeded plants. They are:ssYY (1/16)
ssYy (2/16)Dented, green phenotypeA ssyy plant would be recessive for both traits.There is only 1 genotypes for dented, green seeded plants. It is:ssyy (1/16)A phenotypic ratio of 9:3:3:1A phenotypic ratio of 9:3:3:1 is predicted for the offspring of a SsYy x SsYy dihybrid cross.
9 spherical, yellow
3 spherical, green
3 dented, yellow
1 dented, green
