Answer:
The correct answers are:
1. A. eukaryote 2. B prokaryote 3. A. animals 4. B bacteria
Explanation:
The cell illustrated in A is a eukaryotic cell as it has a membrane-bound nucleus and organelles. The nucleus contains chromatin in the denser area in the center of the nucleus called the nucleolus. An example of this type of cell is animals or plants.
The other cell is a prokaryotic cell as it has no cell organelle or true nucleus. It has a denser area in cell plasm called nucleoid that has chromosome present. The example of these cells are bacteria or archeae.
The michochrindria is the power house of the cell
Answer:
genotype is responsible for establishing phenotype
Explanation:
When Mendel experimented with pea plants, concept of genes and alleles had not come up yet. Through his experiments Mendel first proved that some type of combination in cells leads to a particular phenotype.
He coined the term "factors" which are today known as alleles. These factors paired up and displayed a particular phenotype. Today we know that the alleles are responsible for a genotype which ultimately results in a phenotype. Hence, he established that genotype is responsible for establishing phenotype even before the term genotype was coined.
Answer: Limit the size of fishing fleets and catch size.
Explanation: Cod are nearly extinct therefore we either need to stop catching them or limit the amount you catch
A new DNA strand elongate only in the 5' to 3' direction during DNA replication because the "polarity of the DNA molecule prevents addition of nucleotides at the 3' end" .
DNA replication occurs in the 5' to 3' direction. DNA polymerase can only add nucleotides to the 3' OH group of the growing DNA strand, this is why DNA replication occurs only in the 5' to 3' direction.
DNA polymerase can only add to the 3' end, so the 5' end of the primer remains unaltered. Consequently, synthesis proceeds immediately only along the so-called leading strand.
Hence, the correct answer will be option (B)
