find cos A if sin A=3/5​

Answers

Answer 1

Explanation:

for sin we divide the opposite by the hypotenuse

and for cos we require the adjacent divided by hypotenuse

we can get it through

a²+ b²=c²

ur unknown in this case is the adjustment which you can either substitute with a or b

a² + 3²=5²

a²=5²-3²

a²= 25-9

a²= 16

[tex] \sqrt{a ^{2} } = \sqrt{16} [/tex]

a=4

so that now we have found that I just sent we can find the cos of A

cos A= ⅘

how are proteins made in animals and humans

Answers

Answer:

Through protein synthesis of course...

Explanation:

DNA and RNA do many steps such as translation, transcription, and more to form protein codons and code them into amino acids. Then, thousands of amino acids are oined together to make proteins, which regulate body function and catalyze chemical reactions (enzymes). Ribosomes are also involved in this action. To make proteins, nitrogen is needed for the plant to use, and that comes mainly from nitrate ions in the soil, and gets into the plant by active transport.

How many electrons must get passed down the Electron Transport Chain before energy is generated?

Answers

Answer:

4 electrons

Explanation:

Electron transport chain is defined as the series of process in which electron transfer takes place across a membrane. It is consists of enzymes, peptides, and other molecules.

There are 4 electrons that passed down the Electron Transport Chain before energy is generated. These Four electrons further reduce each molecule of oxygen. Oxygen binds with free proton and form water and move across the membrane to form ATP.

Hence, the correct answer is "4 electrons".

Using the law of conservation of mass, what is the mass, in grams, of the product in the given reaction?

Reactant 1 (35 grams)+ Reactant 2 (115 grams) →Product (? grams)

A. 80

B. 140

C. 150

D. 75

Answers

Answer:

The correct option is;

C. 150

Explanation:

By the law of conservation of mass we have that in a closed system, the mass of the items in the system can not be destroyed or created by a physical process or chemical reaction

In the given chemical reaction process we have;

Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product = ((35 + 115) grams)

∴ Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product (150 grams)

The mass of the product = 150 grams.

Do you have more cells now than you did when you were five?

Answers

Answer:

No After your cell dies of another one come. Your cells are still the same

Explanation:

When you age, cells do divide and reproduce more cells. However when you age the reproduction process of cells gets slower and they can die off before they can reproduce. There can be many problems with your cells that can make cell count lower such as Atrophy, and Dysplasia. When you age, cells are a contributing factor of making you age. They can change your skin, face, etc.. So the answer would be no, you would not have more than you did when you were five.

Why does evolutionary theory absolutely require the earth to be very
old?

Answers

Answer:

Because it takes time for the animals to adapt to their environment, and change their DNA

Answer:

Because evolutions don't happen overnight, it takes years and years for an organism to develop an evolution. So, the earth has to be old, because if we look at the earth when it was young, then we don't really see any evolutions. However, if we look at it when it's old, we can see that there were many evolutions. I hope this helps!

Explanation:

An organism was found. It is unicellular, but its one cell does contain a nucleus and the cell is autotrophic. What type of organism is this?
A
animalia
B
protista
C
bacteria
D
fungi

Answers

Answer:

B protista

Explanation:

The cell is unicellular, so it can not be an animal, which are all multicellular.

It contains a nucleus, which means it cannot be prokaryotic (it cannot be bacteria)

The cell is autotrophic, which means it cannot be a fungus, which are heterotrophs

Therefore, the organism must be a protist, so the answer is B, protista.
