Genetically engineered pork has a higher flesh-to-bone ratio. Which of the following sentences explains how pork is genetically
Oksanka [162]
The answer is A)<span> the desired gene is inserted into the genomes of the pork.

</span>

The techniques of genetic engineering are used to introduce hybrid genes for some desired substance or protein or trait into other organisms. Here, the desired gene is inserted into pork's genome and as a result, it has a <span>higher flesh-to-bone ratio</span><span>.</span>

<span>- B) is not the right answer because it is not necessary to change all the genes in the pork genome or it will be transformed into totally different organism.</span>

<span>- C) is not the right answer because the pork does not have plasmids.</span>

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2​
marissa [1.9K]

Answer:

A 0.015M

Explanation:

Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:

Molarity (M) = mole (n) / volume (L)

Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.

We can calculate the number of moles of KCl in the solution by using the formula:

Mole = mass ÷ molar mass

Where atomic mass of; K = 39, Cl = 35.5

Molar Mass of KCl = 39 + 35.5

= 74.5g/mol.

Mole = 0.83g/74.5g/mol.

mole = 0.01114

Approximately, n = 0.011mol

Hence, molarity = 0.011mol/0.75L

Molarity = 0.0146

Molarity = 0.015M

Astrocytes A. all of these B. induce the formation of the blood-brain barrier C. physically support neurons D. are important in
Keith_Richards [23]

Astrocytes perform the function of all of the given options i.e., induce the formation of the blood-brain barrier, physically support neurons, are important in the repair of brain injuries and in neural formation, take up excess K from the brain ECF.

  • Both invertebrates and vertebrates have Astrocytes, a star-shaped cell kind of neuroglia, in their nervous systems.
  • Astrocytes can be separated into protoplasmic and fibrous kinds. In the central nervous system's white matter, myelinated nerve fibers are frequently surrounded by fibrous astrocytes.
  • Numerous cytoplasmic processes on astrocytes end on axons, neuronal cell bodies, blood vessels, and synaptic terminals.

b) The development of the blood-brain barrier is aided by the Astrocytes

c) Astrocytes support neurons physically and metabolically.

d) Astrocytes help in transfer of blood-borne materials to the neuron, and injury response of the brain and repair of brain injuries.

e) They also help with detoxification, migratory guidance, energy metabolism regulation and removal of excess K from brain ECF.
