carbon
hydrogen
Explanation:
From the given choices, carbon and hydrogen are considered to have a relatively weak degree of electronegativity.
Electronegativity of an element is the tendency with which the atoms of the element attracts valence electrons in a chemical bond.
- Oxygen and nitrogen are highly electronegative elements having a strong attraction for electrons in covalent bonds.
- Carbon and hydrogen have considerably low electronegative values.
According to the Pauling's table showing electronegativities of elements,
N - 3.0
O - 3.5
C - 2.5
H - 2.1
therefore the order of increasing electronegativity is:
H < C < N < O

Answer:
False
Explanation:
Since it's a recessive disorder that means the presence of the dominant allele will overshadow the recessive if it's present. Two recessive alleles have to be present in order for the person to have the disorder.
All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space
The answer should be —10 — 5i
<u>Answer:</u>
The Earth has got its tilted axis and this is the reason for different seasons to be formed. Communities are a set of population found in that particular area and are of two types.
A) Terrestrial (Land)
B) Aquatic (Water).
These communities to flourish need a perfect environment with a perfect season. Hence according to the season formed due to the tilted axis influences the terrestrial community which forms in that particular region and have the ability for the region specific community growth.
The terrestrial community of a tundra or desert or rain forest all depends on the particular season that can be formed due to the position of the earth facing the sun.
