Answer:
16/64 = 1/4
Explanation:
This is a typical trihybrid cross involving three genes T, P and Y. A plant with genotype TTPpYy is crossed with a plant recessive for all traits (ttppyy).
According to Mendel's law of independent assortment, each allele for each gene will get sorted into the following 8 gametes with only 4 different: TPY, TPy, TpY, Tpy, TPY, TPy, TpY and Tpy.
The recessive parent, ttppyy will produce tpy, tpy, tpy, tpy, tpy, tpy, tpy and tpy.
Hence, using a punnet square, 64 offsprings will be produced with only 16 of them heterozygous dominant for the three traits with genotype (TtPpYy). Hence, proportion is 16/64 equivalent to 1/4.
Answer:
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. Antibiotics DO NOT work on viruses, such as those that cause: Colds and runny noses, even if the mucus is thick, yellow, or green. Most sore throats (except strep throat) Flu.
Answer:
B replication
Explanation:
the teacher demonstrated, so the students were told to CARRY OUT THE *same* experiment, AKA REPLICATION >:3
The human gene for insulin production is identified and removed using enzymes called restriction enzymes. The same restriction enzymes are used to cut open a plasmid (a small, circular section of DNA).
Answer:
Cellular respiration
Explanation:
This is because cellular respiration is an aerobic process where the chemical bonds in food are broken down to release energy. This process produce energy which are useful for the body cells. Cellular respiration help to break down glucose. Glucose and oxygen are converted to carbondioxide and water and energy is released which form ATP.
