If we name the gene for pods with A, than the alleles are: A-dominant, a-recessive.
The possible genotypes for the smooth pods are: Aa and AA, while genotype for constricted pods is aa.
If one parent has constricted pods and the other parent is homozygous for smooth pods there are two possible combinations:
P: AA x aa
F1: Aa Aa Aa Aa all of the offspring are constricted
Another combination:
P: Aa x aa
F1: Aa Aa aa aa half of the offspring are with constricted pods and half with smooth pods.
So, the correct answers are:
• all of the offspring will have constricted pods
• 50% of the offspring will have constricted pods and 50% will have smooth pods.
Answer:
trophic level
Explanation:
Each step in the food web is called a trophic level.
Capillaries; veins; arteries
Capillaries allow materials to be exchanged between the blood and tissues, veins carry blood towards the heart, and arteries carry blood away from the heart.
Capillaries are small blood vessels through which molecules such as oxygen and glucose enter the cells.
Veins are tubes or blood vessels that transport blood toward the heart. Veins mostly transport deoxygenated blood towards the heart except the pulmonary and umbilical veins, which transports oxygenated blood toward heart.
Arteries are blood vessels that transport blood away from the heart to other parts of the body. Arteries have elastic walls and they are stronger and thicker than veins.
Answer:
DNA is like a ladder, it's structure is double helix much as the specific sequence on letters on base pairs are like single rung along the genetic ladder and sugar phosphate.
Explanation:
DNA or Deoxyribonucleic acids is a genetic material found in humans and other living organisms. It is located in the nucleus and sometimes it is found in the mitondondrial in small amount.
The information in DNA is stored as a code made up of four chemical bases; Adenine (A), Guanine (G) , thymine (T) and cytosine(C).
DNA replicates and make copies of it self. It is formed by based pairs attached to sugar phosphate.
Answer:
Biodegradable plastics are made from all-natural plant materials. These can include corn oil, orange peels, starch, and plants. Traditional plastic is made with chemical fillers that can be harmful to the environment when released when the plastic is melted down.
