kaheart [24]
The inferior most, or the lowest, sinus cavity is called the maxillary sinus. It is also the largest sinus cavity and it drains into the middle of the nose. The maxillary sinus is located above the upper jaw and is easily visible on x-rays above the premolar and the molar teeth. 
The symptoms of sinusitis include headaches near the sinus and discharge of foul-smelling mucus.

If the nucleotide sequence on one side of a DNA molecule is CCTAGCT, then the sequence on the complementary strand of DNA will b
valentinak56 [21]

Answer:GGATCGA

Explanation:

The complementary double helix of the DNA are antipararell to each other.

Chargaff's rule state that Adenine always pairs with thymine (double bond) and Cytosine always pairs with guanine (triple bond).

Therefore if a DNA molecule is CCTAGCT, then the sequence on the complementary strand of DNA will be GGATCGA as written below

5' CCTAGCT 3'

3' GGATCGA 5'

Why does darkness affect the light-independent reactions of photosynthesis?
notsponge [240]

Answer:

The correct answer would be Light independent reactions require the energy gathered in the thylakoids.

Photosynthesis can divided into two sub-processes or reactions:

Light-dependent reaction: It converts solar energy into chemical energy that is, ATP (adenosine triphosphate) and NADPH with the help of photolysisis of water. It takes place in thyllakoid membrane of the chloroplast.

Light-independent reaction: It fixes carbon obtained from carbon dioxide into the food or glucose with the help of enzyme RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase).

It takes place in the stroma of the chloroplast and does not require the involvement of light however, it requires the products (ATP and NADPH) of the light reaction.

Fixation of 1 molecule of glucose requires 6 molecules of carbon dioxide, 9 molecules of ATP and 6 molecules of NADPH.

So, darkness indirectly affects the light-independent reaction.

HELP I NEED A SCIENTIFIC MODEL AND PARAGHRAPH ABOUT ATOMIC THEROY WILL GIVE BRANLIEST AND POINTS
saveliy_v [14]

<h2>Atomic Theory:</h2><h2>Introduction</h2>

The atomic theory of Atoms Summed up is the idea that all matter is made of tiny particles that are imperceptible to the mortal eye; these particles are named Atoms

<h2>Paragraph 1:</h2>

John Dalton was the first to consider that all matter was made of tiny particles known as atoms. He invented the idea that matter is formed of atoms varying in weight.

<h2>Paragraph 2:</h2>

I created this model of the dissimilarities between three kinds of matter-- solids, liquids, and gases. The distance between atoms in each state tells us what type of matter we observe.

The Drawing is on the file

The End.

I hope you found this helpful
