The correct answers are: the insertion of a DNA sequence into the targeted gene and deletions of the targeted gene

Cas9 is an enzyme endonuclease (which means it cuts nucleotides) that is part of the CRISPR-Cas9 complex- genome editing tool that can remove, add or alter sections of the DNA sequence.

Cas9 recognize the sequence that is going to be cut thanks to guide RNA- pre-designed RNA sequence complementary to sequence of interest. DNA repair machinery will try to fix the “damage” but it can add (insert) or delete some nucleotides.

Based on the phylogenetic tree below, which groups of plants evolved most recently?
xeze [42]

Answer: The correct answer is- gymnosperms and angiosperms.

Phylogenetic tree is a diagrammatic representation that depicts the evolutionary relationship among different group of species. In other words, it is used to interpret the relatedness among different species and how they have descended from a common ancestor.

The tips in the phylogenetic tree represents the taxon ( or particular group of species) that are descended.

In the given tree, gymnosperms and angiosperms have evolved most recently because they correspond to the most recent branches having the immediate common ancestor at the topmost level as compared to the immediate common ancestor of other taxon.

Thus, gymnosperms and angiosperms is the right answer.

The meningeal branch of a spinal nerve actually reenters the vertebral canal to innervate the meninges and blood vessels. The me
Shalnov [3]

Answer:

True

Explanation:

Spinal nerve divides into several branches after passing through its intervertebral foramen. These branches are called rami. A spinal nerve gives off several branches such as anterior ramus, posterior ramus, rami communicantes, and a meningeal branch. The meningeal branch reenters the vertebral cavity through the intervertebral foramen. It serves to supply the vertebrae, vertebral ligaments as well as the blood vessels of the spinal cord, and meninges.

How does the circulatory system interact with the digestive system ?
Alexandra [31]

The digestive system breaks down food molecules into their component parts, which are then absorbed by the circulatory system in the small intestine and circulated throughout the body. The digestive system diffuses nutrients into the capillaries and then through the circulatory system. The small intestine has folds called villi, and the villi contain tiny projections called microvilli. The microvilli absorb nutrients from digested food and transport it directly into the bloodstream where it can be used. Without the circulatory system, the body would not be able to absorb nutrients from the food we eat.

The circulatory system supplies the organs with blood and oxygen to keep them alive. Oxygen travels throughout the body including the digestive system. Like any organ, the digestive system requires more oxygen when metabolically active, for example after a meal. In addition, the digestive system plays a role in the acid-base balance in the body. Since H+ + HC03- exchanges with H20 and C02 within the intestine there is a production of carbon dioxide from the gut to the lungs.

The bloodstream carries nutrients that are broken by the digestive system from the food you eat. The circulatory system provides nutrients and oxygen to the organs of the digestive system.
