Answer:
The correct option is Number 1. AaBb x AaBb
Explanation:
Genes can be described as basic hereditary units. The genes are made up of DNA.
A gene carries two alleles for a particular trait. These alleles are present at the same loci in the homologous chromosomes. If the two alleles are similar then they are termed as homozygous e.g AA, BB. If the alleles for a trait are different then they are termed as heterozygous e.g Aa and Bb.
I think the answer is D. A good indicator is the resting heart rate. Exercise strengthen your heart and it makes it more efficient. The resting heart rate shows of the heart is pumping blood normally each time it contracts. Having a normal resting heart rate would mean a healthy heart.
There are three types of energy involved in a muscle's contraction. There is metabolism, catabolism, and anabolism. Metabolism is the events that are carried out in the human body to create energy and other things needed for activity. Catabolism is the process during the organic matter is broken down and the energy is released, it takes place during increased movement. Anabolism is the energy-consuming process that substances are created, it takes place when there is little movement. All three of these work to gather in muscle contraction.
Prokaryotic cells lack a defined nucleus, but have a region in the cell, termed the nucleoid, in which a single chromosomal, circular, double-stranded DNA molecule is located.
