Answer:
D
Explanation:
DNA pairs with adenosine, thymine, cytosine, and guanine
RNA pairs with uracil, adenosine, cytosine, and guanine
Hello!
Your answer is A. The daughter cells are genetically identical to both each other and to the parent cell.
The parent cell makes two copies of its chromosomes and separates them, then divides by cytokinesis, creating two genetically identical daughter cells.
The answer to this question would be: <span> C) carbon dioxide and water
In cellular respiration, the glucose will react with oxygen, resulting in ATP, carbon dioxide and water. Adenosine triphosphate or ATP is the main product of this reaction since it can be used to produce energy. So, water and carbon dioxide would be the by-product.</span>
Answer:
The correct answer is explained below:
Explanation:
- According to the question, heterozygous tall, heterozygous axillary plant has the following genotype, TtAa.
- It produces the following gametes: TA, Ta, tA, ta.
- The heterozygous tall, terminal plant has the following genotype: Ttaa
- It produces the following gametes: Ta, ta.
- Crossing them,
TA Ta tA ta
Ta TTAa TTaa TtAa Ttaa
(Tall, Axillary) (Tall, Terminal) (Tall, Axillary) (Tall, Terminal)
ta TtAa Ttaa ttAa ttaa
(Tall, Axillary) (Tall, Terminal) (Short, Axillary) (Short, Terminal)
- The genotypes of the offspring obtained are: TTAa, TTaa, TtAa, Ttaa, ttAa and ttaa respectively.
- The phenotypes obtained are:
- Tall, Axillary = 3.
- Tall, Terminal = 3.
- Short, Axillary = 1.
- Short, Terminal = 1.
Oxygen entered the Earth's atmosphere after the appearance of the Great Oxidation Event (Great Oxygenation Event). The Great Oxidation is the first mass extinction on Earth.
The Great Oxidation lasted 2.4 to 2.0 billion years ago.
Oxygen appeared on Earth thanks to cyanobacteria using photosynthesis.
