differentiate between wing and feather
Answer:
In most bird species, there are 10 primary feathers on each wing. If these flight feathers are damaged or lost, a bird cannot fly. Secondary feathers: These run along the 'arm' of the wing and sustain the bird in the air, giving it lift. The number of secondary feathers varies with different species.

Hi Tony :D
Stars are hot objects and give off heat and light. Scientist can collect this energy and tell what two things about stars (even though we cannot observe or measure the star directly).
a.composition
b.temperature
c.exact mass
d.shape
Answer: A or c
Explanation:
Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.
What is Stars?A star is the most well-known celestial object and the main building block of galaxies. The age, distribution, and composition of a galaxy's stars can be used to determine the galaxy's history, dynamics, and evolution.
In addition, stars generate and disperse heavy elements like carbon, nitrogen, and oxygen, and their characteristics are strongly tied to those of any planetary systems that may develop around them.
The study of the origin, development, and death of stars is thus at the heart of astronomy.
Therefore, Stars are hot objects and give off heat and light. Composition and exact mass are the things about stars.

Which detail from the excerpt develops the idea that scholars faced many challenges in deciphering the meaning of the
decree on the Rosetta Stone?
more complete copy of the same decree
found on a slab at Philae in 1848
O A Latin version came out in 1851
O many of the hieroglyphs on this slab were missing
Read the excerpt from The Riddle of the Rosetta Stone, by James Cross Giblin.
Another, more complete copy of the same decree that appeared on the Stone was found on a slab at Philae in 1848. Fuller translations of the hieroglyphic text soon followed. A Latin version came out in 1851, a French one in 1867, and an English one in 1871. But many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone.
Which detail from the excerpt develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone?
Answer:
many of the hieroglyphs on this slab were missing
Explanation:
The detail from the excerpt that develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone is "many of the hieroglyphs on this slab were missing."
From the available excerpt, it was written that despite many translations of the original text, including the fuller version, the French translation, the Latin version, and the English version, "many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone."
Answer:
(D) Many of the hieroglyphs on this slab were missing
Explanation:
Think of it like this,
Let's say you were a scholar. If you had all of the hieroglyphs on this slab, the work would be much easier.
However, if you didn't have all the hieroglyphs, you would have to go through the trouble to find the missing hieroglyphs.

Would it be justified to call Kreb's Cycle the central wheel of metabolism? Why? Provide two specific pieces of evidence to support your answer.
Answer:
Yes.
Explanation:
Kreb's Cycle is considered as the central wheel of metabolism because the fuel molecules are oxidized ultimately within the Krebs Cycle and its intermediates are used for various biosynthetic pathways. The main function of the Kreb's cycle is to produce electron carriers that can be used in the cellular respiration for producing energy molecules in the form of ATP. without Krebs's cycle, the cell produces only two ATP molecules which very low.
