2 or more different atoms are combined in definite proportions in any compound.
An extra chromosome will produce an aneuploidy. It may have severe consequences on the resulting zygote.
<h3>Aneuploidies and chromosome abnormalities</h3>
The term 'chromosome abnormalities' refers to different types of problems that occur in meiosis which are associated with the disjunction of chromosomes.
The most common chromosomal abnormality is called aneuploidy, which means an abnormal number of chromosomes.
Aneuploidy is caused by the presence of an extra or due to the lack (missing) of a chromosome during meiosis.
For example, a trisomy is an aneuploidy due to the presence of an extra chromosome (three copies of the same chromosome instead of two).

Answer:
A) cyclic and predictable
Explanation:
The graph shows changes in the water levels (in feet, ft). The water cycle consists of water that evaporates from the surface (land and sea) and subsequently returns in form of rain and/or snow. In general, water levels may be unpredictable in short term but predictable in the long term. The graph shows that this process is cyclic because it is regularly patterned and also occurs in regular intervals (therefore being predictable).
Answer: protein structure
Explanation:
In Sickle-cell anemia, the gene sequence of hemoglobin is changed in its sixth position due to the substitution of glutamate with valine.
So, since glutamate, an amino acid soluble in water due to its hydrophilic side chain is substituted with valine, an amino acid that has a hydrophobic side chain insoluble in water or bloodstream; the resulting hemoglobin protein is altered in structure (sickle shaped) and unable to bind and transport oxygen efficiently to the various body parts.
Answer:
Photosynthesis-
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities. Photosynthesis occurs in the chloroplast of a plant, which contains chlorophyll. In order for photosynthesis to take place, it needs to have water and carbon dioxide, the two very important raw materials necessary for this process. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as this energy-rich molecule known as glucose. Oxygen the by product of photosynthesis is inhaled by heterotrophs which aids in cellular respiration and other internal processes and then exhales carbon dioxide. ... In like manner, carbon dioxide passes from blood to the alveoli and exhaled after
