How has the concept of a "planet" changed since the 16th century? Do you think this shows scientific accuracy or disproves future facts, as one assumes that they will be discredited in time too?

Answers

Science keeps "improving", so the scientific theories and ideas from the past are either expanded on or proved to be false. The concept of planets has definitely seen changes, with Pluto peven being considered not a planet. In the 20 century we believed there were 9 planets but now there is considered to be 8. Science exists as it is but as humans we are constantly discovering more of it because of improvement in the times and technology. Science that proves to be accurate will never be discredited though it will be improved upon .

Answer:

 l

\/

Explanation:

In the 16th century everyone thought everything revolved around the Earth. It wasn’t till the 17th century that everyone got it right that everything revolved around the Sun. I think both as we get better at understanding things our world becomes bigger and everything could change. One day we could find something different and the next day it will be totally different.

In angiosperms, what is the name of the outer epidermal layer that protects the plant body?A. Vascular tissue / B. Dermal tissue/ C. Ground tissue

Answers

The Dermal Tissue (B) is the outer part of the plant that covers the surface of the plant. This epidermal layer protects the soft tissues of plants, protects the plant from injury and water loss and controls interactions with the plants' surroundings.

The correct answer is

B. dermal tissue

Sodium has one electron in its outer energy level. According to the octet rule, _____.

Answers

A sodium atom has a single electron in its outermost electron shell, the first and second shells again being full with two and eight electrons respectively. To remove this outer electron requires only the first ionization energy, which is +495.8 kJ per mole of sodium atoms, a small amount of energy. By contrast, the second electron resides in the deeper second electron shell, and the second ionization energy required for its removal is much larger: +4562.4 kJ per mole. Thus sodium will, in most cases, form a compound in which it has lost a single electron and have a full outer shell of eight electrons, or octet.


Answer : According to the octet rule, sodium wants to lose an electron.

Explanation :

The given element is sodium with atomic number 11 that means it has 11 electrons.

The electronic configuration of sodium will be,

1s^22s^22p^63s^1

From the electronic configuration, we see that one electron of sodium present in its outer energy level. Sodium can be lose one electron easily for the stable electronic configuration.

According to the octet rule, sodium has the tendency to lose one electron and form positive ion with the charge (+1).

Hence, according to the octet rule, sodium wants to lose an electron.

The function of glycogen phosphorylase is: question options: a. the conversion of glucose-1-phosphate to glucose-6-phosphate.
b. inhibit the production of glucose-1-phosphate.
c. to breakdown atp.
d. stimulate the buildup of glycogen.
e. catalyze the phosphorolysis of glucose-1-phosphate from glycogen molecules.

Answers

Answer:
             The correct option is e (catalyze the phosphorolysis of glucose-1-phosphate from glycogen molecules).

Reason:
              It is that type of enzyme which is responsible for the conversion of glycogen into glucose through a series of reactions. First of all glycogen is converted to glucose 1-phosphate catalysed by glycogen phosphorylase. It is then converted into glucose 6-phosphate with the help of phosphoglucomutase. In liver it is then converted into glucose which enter into blood stream.
I hope it will help you. If not then look at diagram you will easily understand the phenomenon. 

Final answer:

Glycogen phosphorylase catalyzes the phosphorolysis of glucose-1-phosphate from glycogen molecules, playing a critical role in the process of glycogenolysis. It helps in the conversion of stored glycogen into glucose for use as energy by the body.

Explanation:

The function of glycogen phosphorylase is to catalyze the phosphorolysis of glucose-1-phosphate from glycogen molecules. What this means is that it helps to break down glycogen, a form of energy storage in animals, into glucose-1-phosphate. In other words, glycogen phosphorylase plays a critical role in the process of glycogenolysis, which is the process of converting stored glycogen into glucose for use as energy by the body. It does this by adding a phosphate group to the glycogen molecule, creating glucose-1-phosphate, which can then be converted into glucose-6-phosphate and ultimately used to generate ATP, the cell's primary energy currency.
