Why is the sky blue

1 answer:

4 0

Answer: <em>Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Closer to the horizon, the sky fades to a lighter blue or white. </em>

Explanation: Hope it help have a great day

For the reaction C6H 1206C02+ H208 428 g of C6 H 1206 is consumed producing a 3.1 M solution of CO2 what is the volume of CO2 pr

timofeeve [1]

I think it’s m(C6H12O6) = 856 g

M(C6H12O6) = 12*6+1*12+16*6 = 180 g/mol

n(C6H12O6) = m/M = 856 g / 180 g/mol = 4.756 mol

n(CO2) = 6*4.756 = 28.536 mol

M(CO2) = 12+16*2 = 44 g/mol

m(CO2) = n*M = 28.536mol*44g/mol = 1255.584 g

Describe the cell membrane, cell wall, nucleus, and cytoplasm. which of these structures are you likely to find in a prokaryotic

Morgarella [4.7K]

Answer:

you can see below

Explanation:

Basic Definitions:

Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.

Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.

Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.

Cytoplasm = The watery, salty, and protein filled 'soup' that fills the cell. All organelles float happily in this.

Now Specific Locations:

Eukaryotic cells

have plasma membranes

please mark me brainliest or mark me thanks at leat

only have cell walls if the cells are plants.

They do have a nucleus.

They have cytoplasm

Prokaryotic cells

have plasma membranes

cell walls are usually chemically complexed.

don't have a nucleus

have cytoplasm

Animal cells

only have the plasma membranes.

No cell wall

have a nucleus

have cytoplasm

Plant cells

have both the cell wall

and have a plasma membrane

have a nucleus

have cytoplasm

The question is the following :
<span>What is the best evidence to prove that Irene was heterozygous for hemophilia?
A) Alice carried the recessive allele.
B) Alexandra carried the recessive allele.
C) Frederick carried the recessive allele.
D) Waldemar carried the recessive allele.

The correct answer is A

In the pedigree, marked with blue are the carriers of the X recessive allele ( they have one X that has the mutation and the other that doesn't).
Alice was Irene's' mother, and since both Alice and iIrene have the allele, it is safe to conclude that Irene inherited the recessive allele from Alice.</span>

Explain how prokaryotic and eukaryotic cells are similar

STatiana [176]

Answer:

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.
