Which tiny, round “factory” puts together protein and is often found in the endoplasmic reticulum?A.
chromosome


B.
chloroplast


C.
Golgi body


D.
ribosome

Answers

In the cytoplasm, ribsomal RNA (rRNA), a type of RNA, andprotein combine to form a nucleoprotein called a ribosome. The ribosomeserves as the site and carries the enzymes necessary for proteinsynthesis. They are often takes the shape of small round particlesattached in the endoplasmic reticulum. The ribosome attaches itself to m-RNAand provides the stabilizing structure to hold all substances in position asthe protein is synthesized. Several ribosomes may be attached to a single RNAat any time.   
i believe that the answer is B , chloroplast. you can work out the problem any other wat too.

i hope this helps

How does a scientific theory compare to a scientific law?​

Answers

Answer:

Explanation:

Scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept.

a gas has a volume of 590 mL at a temperature of 590 mL at a temperature of -55.0 degrees Celsius. What volume will the gas occupy at 30.0 degrees Celsius?

Answers

Answer: The volume that gas occupy will be 820.04mL.

Explanation:

To calculate the volume of the gas at different temperature, we will use the equation given by Charles' Law.

This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

V\propto T

or,

(V_1)/(T_1)=(V_2)/(T_2)

where,

V_1\text{ and }T_1 are the initial volume and initial temperature of the gas.

V_2\text{ and }T_2 are the final volume and final temperature of the gas.

We are given:

T(K)=273+T(^oC)

V_1=590mL\nT_1=-55^oC=218K\nV_2=?mL\nT_2=30^oC=303K

Putting values in above equation:

(590)/(218)=(V_2)/(303)\n\nV_2=820.04mL

Hence, the volume that gas occupy will be 820.04mL.

The blue color of the sky results from the scattering of sunlight by molecules in the air. The blue light has a frequency of about 7.03 × 1014 Hz. Calculate the wavelength (in nm) associated with this radiation, and calculate the energy (in joules) of a single photon associated with this frequency. Enter your answers in scientific notation.

Answers

Answer:

λ = 426.7 nm

E = 4.66 x 10⁻¹⁹ J

Explanation:

The equation of frequency is:

f = v / λ

v: velocity

λ: wavelength

λ = v / f

λ = 3 x 10⁸ m.s⁻¹ / 7.03 x 10¹⁴ Hz

λ = 426.7 nm

The energy of a single photon is

E = hf

h: Plank's constant = 6.63 x 10⁻³⁴ m²kgs⁻¹

E =  6.63 x 10⁻³⁴ m²kgs⁻¹ x 7.03 x 10¹⁴ Hz

E = 4.66 x 10⁻¹⁹ J
