DNA is composed of smaller subunits know as Nucleotides. The three parts of a nucleotide are Sugar, phosphate, and a nitrogen base. The four nitrogen bases that are found in DNA are Adenine, cytosine, guanine, and thymine.
If it goes in the nostrils the air is warmed and humidified. The tiny hairs) protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air.
<u>Examples of places where Hummingbirds live:</u>
- Alaska all the way to Chiles
<u>Traits of Environment</u>:
- forested and wooded
- lots of flowers
- has grasslands and meadows
- marshes and Riparian corridors
- Desert scrublands
- Canyon
- Gardens and backyards
*hummingbirds really do live in diverse areasso that's why can live in so many different areas
Hope that helps!
Probably C. Neutral pH doesn't affect anything, and water is polar so D isn't correct. I don't know what liquid form is, and water does form intermolecular hydrogen bonds, which creates surface tension and makes water form globules. That's how water striders can walk on water because they use the bonds and surface pressure to support them
<h3>Answer</h3>
29.2°
<h3>Explanation</h3>
Given in the question,
radius of circle = 4 m
area of sector = 5π m²
The area of a sector of a circle is
<h3>½ r² ∅</h3>
<em>where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle.</em>
<em />
<h3>area of a sector = ½ r² ∅</h3>
5π = ½ r² ∅
5π * 2 = r² ∅
10π = r² ∅
10π = 4² ∅
10π = 16∅
∅ = 16 / 10π
∅ = 8/5π in radians
<h3>Converting rad to degree</h3>
π = 180°
1rad = 180/π
8/5π rad = 8/5π * 180/π
= 8/5π × 180/π
= 29.2°
