Correct Answer: a DNA strand with the base sequence TTCGACCCT
Correct Answer: Store and transmit Heredity
Explanation:
Protiens can help fight specific diseases, always there to regulate cell processes and build muscle/tissues.
Structural proteins also known as Fibrous proteins, are necessary components of your body. They include collagen, keratin and elastin. Collagen forms the connective framework of your muscles, bones, tendons, skin and cartilage. Keratin is the main structural component in hair, nails, teeth and skin.
Correct Answer: All the above
Explanation:
Asbestos can cause
Benzene can cause
Cadmium can cause
Correct Answer: transfer of pollen from anther to stigma
Explanation:
Pollination is when pollen grains from an anther, the male portion of a flower, are transferred to a female part of the flower, known as the stigma. In order for pollination to be successful, the pollen grains transferred must be from a flower of the same species.
After the pollen grains land on the stigma, they create a pollen tube through the length of the style or stalk connecting the stigma and ovary. Once the pollen tube is complete, the pollen grain will send sperm cells from the grain down to the ovary. When the sperm cells reach the ovary and the egg cells, fertilization will occur, which will result in the formation of the seed. The seed will then be released from the parent plant and will be able to grow into a plant and continue the reproductive cycle using the method of pollination.
Correct Answer: Dodo
Correct Answer: FALSE
Explanation:
Angioplasty, also known as balloon angioplasty or PTA, is a minimally invasive, endovascular procedure to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis.
Hence, the given statement that Angioplasty is the most typical treatment for arteriosclerosis is FALSE.
Correct Answer: both a & b
Correct Answer: Ribosomes
Correct Answer: Pulmonary Veins
Explanation:
The oxygenated blood flows through pulmonary veins then leaves the lungs, which return it to the left heart, completing the pulmonary cycle.
Correct Answer: k
