Answer: Sexual reproduction: rabbits and dolphins.
Asexual reproduction: Strawberry and potato.
Explanation:
- Sexual reproduction is carried out with the participation of germ cells from two stem organisms - female and male, which transfer the properties of the inherited material to the new plant. The main characteristic of sexual reproduction is the division of the relative fusion of male and female sex cells. The end product of this relationship is the creation of an organism that contains the genetic information of both parents.
- Asexual reproduction is a habit that produces an organism identical to the parent organism, and we call this product clones. This form of reproduction does not involve the germ cells and may occur by division or budding. Many types of plants reproduce in this way. So the strawberries are propagated by boils, and the potatoes are buds from the tub
Cell membranes are not solid structures.
Answer:
A single nucleotide changes in CCG which will result in missense mutation can be many possibilities.
Explanation:
Missense mutations
CCG codes for Proline amino acid
• Mutation in first nucleotide codes for
UCG specifically encodes Serine
ACG specifically encodes Threonine
GCG specifically encodes Alanine
Missense mutation
• Mutation in second nucleotide specify for coding
CUG specifically encodes Leucine
CAG specifically encodes Glutamine
CGG specifically encodes Arginine
• Mutation in Third Nucleotide will not result in missense mutation because any point mutation in third nucleotide of codon will encode same amino acid i.e Proline.
Answer:
Older rock layers are found under younger rock layers
Explanation:
It directly states in the sentence above the diagram that the bottom layer of rock is the oldest.
