Answer:
A. Two different forms a plant can have
Explanation:
Higher plants, lower plants (mosses) and ferns undergo a life cycle called ALTERNATION OF GENERATIONS. In this life cycle, they switch between a haplontic and diplontic forms of life.
The haplontic (haploid) life form which produces haploid (n) gametes is called GAMETOPHYTE while the diplontic (diploid) life form which produces the spores that germinates is called SPOROPHYTE. Hence, sporophyte and gametophyte are two different forms a plant can have.
Answer:
A protein's primary structure is defined solely by its amino acid sequence, and is constructred by peptide bonds between adjacent amino acid residues. Secondary structure results from hydrogen bonding along the polypeptide backbone, resulting in alpha-helices and beta-pleated sheets.
The correct answer for the question that is being presented above is this one: "(3) all cells in his body." A man is exposed to large amounts of ultraviolet radiation while sunbathing on the beach. This exposure causes genetic change in the DNA of a skin cell. In the future, this change can be passed on to (3) all cells in his body.
Here are the following choices:
(1) his male and female children
(2) his male children, only
(3) all cells in his body
(4) his skin cells, only
Answer:
The bee travelled a total distance of 11.7 metres, in order to collect pollen from a flower and then back to its hive.
Note: The question is not clearly stated. A similar but clearly stated question is given below:
A bee flew 840 cm and landed on a flower to collect some pollen. Then the bee flew another 330 cm to get back to her hive. How many meters did the bee travel?
Explanation:
Th distance travelled by the bee is the sum total of all the ground covered by the bee.
The initial distance travelled by the bee to get to the flower = 840 cm
After collecting pollen from the flower, the distance travelled by the bee to get to its hive = 330 cm
The total distance travelled by the bee = 840 cm + 330 cm = 1170 cm
The distance covered in centimetres is then covered to metres
100 centimetres = 1 metre
Therefore, 1170 cm = 1170 cm × 1 m /100 cm = 11.7 m
Therefore, the bee travelled a total distance of 11.7 metres, in order to collect pollen from a flower and then back to its hive.
