Plants require pH to thrive which in turn gives us food.
Answer: beta, gamma, alpha
Explanation: Beta is weakest gamma is middle alpha is strongest
Answer:
closer to F because fluorine has a higher electronegativity than carbon
Explanation:
Electronegativity refers to the ability of an atom in a bonding situation to draw the shared electrons of the bond closer to itself.
Electronegativity increases across the period and decreases down the group. A highly electronegative atom draws the shared electron pair of a bond towards itself.
When two atoms are bonded together, the electron pair is always drawn closer to the atom that has a higher electronegativity.
Hence, the electron pair in a C-F bond could be considered closer to F because fluorine has a higher electronegativity than carbon.
Selective breeding
The Alleles
DNA
X and Y chromosome from mother and father
Nucleus
Gene
<u>Explanation:</u>
- In selective breeding, a specific trait of the animal is considered and the gene coding for that trait is used to create new breeds. Example - cow producing lot of milk.
- Genotypes are always expressed by the alleles.
- Example - Genotype of Tall plants would be TT or Tt
- Information is passed from parents to offsprings from the information stored in DNA.
- A gender of an individual is determined by the x chromosomes of mother and X and Y chromosome of father.
- X chromosome from mother and X chromosome from father would form a female and X chromosome from mother and Y chromosome from father would form a male.
- DNA is located inside the nucleus of the cell
- Gene is the segment of chromosome that codes for a specific protein. The non coding segment of chromososme is heterochromatin.
