Photosynthesis converts carbon dioxide and water into oxygen and glucose. This occurs in plants. Glucose is used as food by plants and has oxygen as a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

mihalych1998 [28]

Answer:

The correct option is number 3.  A deficit of appositional bone growth would not be life threatening.

Explanation:

Appositional bone growth can be defined as the thickening of the bones due to increase in the number of bone tissues at the surface. In this kind of bone growth, the diameter of the bone increases rather than the length of the bone. This can lead to deformation of the bone but it is not life-threatening.

Rest of the options 1, 2 and 3 are serious disorders and can eventually lead to death.

Describe the chemical components of DNA.
Slav-nsk [51]

DNA is composed of nucleotides, which are composed of three parts:

1. A five carbon carbohydrate (pentose)

Pentose is classified as a monosaccharide (simple carbohydrate), and its molecular formula is represented by (CH_{2} O)n. They are water soluble molecules with sweet taste. Monosaccharides may have from three carbon atoms (trioses) to six (hexoses). In DNA is present pentose (5 carbon atoms)

2. A nitrogenous base

Nitrogenous bases are ring-shaped compounds that contain nitrogen in their molecular structure. They are classified into two groups: purines and pyrimidines

The purine bases are adenine (A) and guanine (G). They are larger and contain more than one ring in their structure,.

The pyrimidines, cytosine (C), uracil (U) and thymine (T), are smaller and composed of a single ring.

3. One or more phosphate groups

A phosphate consists of a trivalent anion that contains one phosphorus atom and four oxygen atoms. Its molecular formula is expressed by (PO_{4} ^{-3}).

If a double foul occurs during a down in which time expires, the period is ended
Zina [86]
This statement is false.

Double fouls are when two players on opposing teams commit a foul, which makes the fouls of the players "cancel out" and ball possession does not change. However, personal fouls are still charged on both of the offending players.
