If thats the question, Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
Answer:
If the covalent is polar its means that pair of electrons are unequally shared between both atoms.
Through electronegativity difference.
Explanation:
Covalent bond:
It is the bond which is formed by the sharing of electrons between the atoms.
It is weaker than the ionic bond. The both bonded atoms do not completely transfer the electrons but can only shares.
For example:
The bond between the both chlorine atoms Cl₂ is coavlent. Cl:Cl
The bond between the H₂ atoms is covalent. H:H
The covalent bond can be polar or non polar. When it is formed between the atoms of two different elements then electronegativity difference is created. The atom atoms with high electronegativity values attract more strongly the shared pair of electron towards it self and become partial negative while the other became partial positive. Thus bond become polar.
But this is only in case when the electronegativity difference between both atoms is 0.4 are greater. If the difference is less than 0.4 than bond is non polar.
For example:
HCl, H₂O
The polar covalent bond is present in HCl and water because of greater electronegativity difference between hydrogen and chlorine , oxygen and hydrogen.
Answer:
They do have protein in the meat and pork but also a lot of corbohydrate, Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P). So it could Be (C) or D

Photosynthesis provides the ingredients for the mitochondria to perform cellular respiration. Cellular respiration then provides the ingredients needed to perform photosynthesis. And it goes on and on in a cycle
There are a lot of factors that can increase serotonin in the brain. For example increasing exercise, sunlight or vitamin B6 could all create a natural increase of serotonin. serotonin is also greatly affected by stress levels so one could say that increased relaxation would increase serotonin.
