Sexual reproduction is a process involving the fusion of two gametes to
Gametes are special reproductive cells produced by meiosis. It produces genetically dissimilar offspring. Offspring may inherit beneficial qualities from both parents and there is a greater genetic variation in the offspring, leading to species that are better adapted to changes in the environment.
Answer: Option D.
It is an evidence -based report.
Explanation:
An evidence based report is a report that is written based on scientific evidence to draw out conclusion or arguments for guidance and decision making for the people.
The article that was written, was base on some scientific proof that vegetables lack some nutrients. The vegetables have been analyzed and the constituents have been known. Conclusion was arrived at the Americans need to take dietary supplements to meet up with the daily nutrients requirements while taking vegetables.
Answer:
B. Primary spermatocytes
Explanation:
The germ cell line is a group of cells found inside the seminiferous tubules. This germ cells undergo mitosis (creating spermatogonia) to have a steady supply of cells that will divide by meiosis to produce gametes. When spermatogonia divide by meiosis at the end of meiosis I the newly created cells are known as primary spermatocytes.
Answer:
Option B, Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
Explanation:
Options for the question are
A) Apply auxin directly to the shoot tip on the side to which you want the tip to bend.
B) Apply auxin directly to the lower part of the stem opposite from the direction you want the stem to bend.
C) Inject compounds that block auxin receptors into the part of the stem opposite from the direction you want the stem to bend.
D) Plant the roots in two different pots, and apply auxin to the root bucket that is on the same side as the direction you want the plant to bend.
Solution
Auxin is responsible for stem elongation by inhibiting growth of lateral buds. The movement of auxin is opposite to the direction of elongation of cells. Generally, Auxin moves to the dark side which is opposite to the direction i.e the lighter side in which cell elongate . Due to this growth pattern, the stem tip gets curved towards the light.
Hence, option B is correct
Answer: d - water forming on the lid under the container
Explanation:
Condensation is the process that describes the change of state of water from gas to liquid. It happens in the water cycle when water vapor gets to the atmosphere and due to the lower temperatures turns into liquid water that then forms clouds.
In the demonstration, the container is meant to be the clouds so when water forms under the container, that is condensation happening because the water vapor has not turned back to liquid after leaving the aquarium water as water vapor.
