One line with red flowers and the other line with violet flowers. You carry out a monohybrid cross and find that all of the F1 offspring have violet flowers, while 97 of 400 F2 offspring have red flowers.
Explain the inheritance of flower colour in this plant species.
Answers
Answer:
See the answer below
Explanation:
The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.
Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r. The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:
RR x rr
F1 Rr Rr Rr Rr
phenotype ratio = all violet flower color
Rr x Rr
F2 RR Rr Rr rr
phenotype ratio = 3/4 violet flower color and 1/4 red flower color
97 red flower offspring out of 400 is approximately 1/4.
Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.

a. It inhibits guanylyl cyclase in smooth muscle cells.
b. It prevents acetylcholine from binding to its receptors.
c. It stimulates guanylyl cyclase in smooth muscle cells.
d. It blocks the enzyme that degrades cyclic GMP.
e. It binds to acetylcholine receptors on endothelial cells.
Answers
Answer:
The correct answer is option d, that is, it prevents the enzyme, which degrades cyclic GMP.
Explanation:
Oral therapy for erectile dysfunction is Viagra, which is the citrate salt of sildenafil, it works by preventing a specific phosphodiesterase type 5 or PDE5, which is the inhibitor of cGMP. During sexual stimulation, nitrous oxide is released in the corpus cavernosum causing the erection of the penis in males. The nitrous oxide then stimulates the enzyme guanylate cyclase that further makes the concentration of cGMP to elevate, this generates smooth muscle relaxation in the corpus cavernosum and permitting blood the inward flow of blood.
Viagra works by increasing the influence of nitric acid by preventing PDE5, which is accountable for the deprivation of cGMP in the corpus cavernosum. At the time of sexual stimulation, the discharging of nitrous oxide takes place, the viagra inhibits PDE5 causing the levels of cGMP to elevate in the corpus cavernosum leading to smooth muscle relaxation and continuous flow of blood to the corpus cavernosum.

What is the probability of short beaks in the offspring of the cross show above
Answers
Answer:
8/16 or 1/2
Explanation:
This question is a dihybrid cross involving two genes, one coding for feather color and the other for beak length. The alleles for green feathers (G) and long beak (L) are dominant over the alleles for yellow feathers (g) and short beak (l).
According to this question, a male with genotype GGLl was crossed with a female with genotype Ggll. The following combination of gametes is produced by each parent:
GGLl - GL, Gl, GL, and Gl
Ggll - Gl, Gl, gl and gl
Using these gametes in a punnet square (see attached image), the following offsprings in the following proportions will be produced.
Green feathers, long beak (GGLl, GgLl) = 8/16 or 1/2
Green feathers, short beak (GGll, Ggll) = 8/16 or 1/2
Hence, the probability of short beaks (ll) in the offspring of the cross is 1/2.

The soil particle size has the greatest effect on soil's capacity to retain water.
Soil particle size and organic matter (the soil's composition) are main determinants of water-holding capacity of a soil. Smaller particles (silt and clay) have a bigger surface area than larger sand particles, allowing the soil to hold more water.Learn more about the water holding capacity of soil: https://brainly.com/question/8464940

Which two terms describe this type of bone fracture?
simple, incomplete
compound, complete
simple, complete
compound, incomplete
Answers
The correct answer is Compound, complete
Explanation:
Bone fractures occur as bones (hard tissue that is part of the skeleton) break, which can be caused by traumatic incidents, certain diseases, among others. Moreover, fractures are classified into different categories such as compound/simple, complete/ incomplete depending on the characteristics of the bone fracture.
In the case of compound fracture, this occurs if the bone is exposed. This means the bone breaks and then displaces causing an open wound. This occurs in the bone fracture from the image because the bone has moved to the left and break the skin, muscle, and other tissue of the area. On the other hand, a fracture is complete is the fragments of the bone are completely separated, which occurs in the image because the bone has been completely divided into two sections.
