Answer:
The two genes are linked together
Explanation:
<em>The conclusion that can be drawn about the arrangement of the genes on the chromosome in the Aa Bb parent is that the two genes are linked together. That is, they do not assort independently.</em>
When two genes are linked together, the number of recombinant offspring would be more than the number of offspring with parental traits. The frequency of recombination would also not exceed 50%.
<em>Recombination frequency = number of recombinant offspring/total number of offspring x 100%</em>
Number of recombinant offspring = 45 + 45 = 90
Total number of offspring = 45 + 45 + 5 + 5 = 100
Recombination frequency = 90/100 x 100% = 10%
Hence, the two genes Aa and Bb are said to be linked together.
Answer: D
Explanation: the continents wee once connected. It was known as Pangea
Produces a replication bubble with a replication fork on each side.
Answer:
D
Explanation:
Absolute age is defined as the numeric age of fossils.
To identify the absolute age of a fossil, the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.
Hence, the correct answer is "D".
Red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.
<h3>
What are proteins?</h3>
The term "protein" refers to a macro- and large-scale biomolecule that has one or more lengthy chains of amino acid residues. An amino acid chain makes up the basic building block of proteins.
When oxygen binds to the heme portion of the hemoglobin molecule in red blood cells during physiological respiration, oxyhemoglobin is created. This procedure takes place in the pulmonary capillaries close to the lung's alveoli.
Thus, red blood cells contain a protein called hemoglobin. An illustration of red blood cells showing the hemoglobin protein. This protein serves as a transporter of oxygen from the lungs to tissues.
