Answer:

Dragon fruit, a kind of fruit belonging to Hylocereus spp., has brought about interest in China not only due to its important economic value with high contents of nutrients, but also due to the striking tolerance to drought stress. Fifteen morphological traits and 111 Inter-Simple Sequence Repeat (ISSR) markers generated from 16 primers were firstly employed to discriminate 50 accessions recently selected in China, as well as to evaluate their genetic relatedness. According to univariate statistical analysis of morphological traits, high variations were observed between or/and within the wild and cultivated lines. The dendrogram of 50 accessions was constructed based on morphological traits. Taking 7.50 as a threshold, three major clusters could be observed, i.e. the first included nine genotypes, which mainly belonged to wild accessions; the second clusters standing for the red pulp genotypes; the third consisting of the white pulp accessions. Each ISSR primer generated 4–10 obvious DNA bands ranging from 100 bp to 1500 bp, with the average of 6.9 per primer.

Helppp please Explain your observations in terms of potential and kinetic energy

Kryger [21]

Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts. However, it isn't affected by the environment outside of the object or system, such as air or height. On the other hand, kinetic energy is the energy of an object or a system's particles in motion.

Hope this helps!

What is relationship among the location of volcanues,earthquake epicenter,and mauntain ranges?

Korolek [52]

Volcanoes, earthquakes and mountain ranges are all results of the tectonic movement of the Earth.
When two plates collide and one does not completely give way and go under the other the crust is pushed up forming mountain ranges.
An earthquake is the shaking and vibration of the Earth's crust due to movement of the Earth's plates (plate tectonics).
And volcano is created when plates are pushed together or pulled apart.
So, the relationship between volcanoes, earthquakes and mountain ranges is their connection with the tectonic movement of the Earth.

Achondroplasia is an autosomal dominant genetic disorder in humans. If a man with Achondroplasia ( heterozygous) and a normal wo

tresset_1 [31]

Answer and Explanation:

Achondroplasia is a form of dwarfism that affects the formation of cartilage; early in development, most of the skeleton is comprised of cartilage. Cartilage is a type of flexible, tough tissue; in achondroplasia ossification (conversion of cartilage to bone) is affected. Symptoms include an enlarged head, shorter upper and lower limbs, and limited motion at the elbow.

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding.

For this cross...

Assuming Achondroplasia= dominant

Parent generation or P generation:

gametes: An → Achondroplasia dominant (A), No Achondroplasia recessive (n)

Heterozygousity describes the allelic makeup; these traits comprise two varying forms of a gene. However, homozygous traits comprise identical forms of the gene.

Male: An → with Achondroplasia

Female: nn → without Achondroplasia

genotypes and phenotypes for parent and offspring...

Assuming heterozygousity of the male , for the cross

P generation: An × nn

Achondroplasia × No Achondroplasia

F1 generation:

genotype: An × nn ...(from punnet square)

phenotype: 2 with Achondroplasia ; 2 without

∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with Achondroplasia ; 2 without

Which explains how the greenhouse effect and greenhouse gases can cause problems with earth’s energy budget? A. The more green

dangina [55]

C. The more greenhouse gases that are in the atmosphere, the more heat will be trapped. That means earth’s energy budget could be disturbed because the amount of heat radiating toward the surface is greater than the amount of heat escaping from the earth
