From the options given above, the correct option is D. A haploid cell is a cell that contains a single set of chromosomes only. A haploid cell can only undergo asexual reproduction. Asexual reproduction involves only one parent and the cell division usually occurs by mitosis. An organism that is reproducing asexually will transmit 50% of its gene to its offspring[s]. Thus, haploid cells reproduce asexually through mitosis only.
The image given is incomplete. The complete image is attached below.
Answer:
A. A Squirrel, robin, and field mouse
Explanation:
Food web is defined as the interconnection between different food chains which shows how organisms from different food chains are connected with each other for food in the ecological community.
In the attached image, there are three consumers which depend on the same producer for food. Those three consumer are squirrel, robin, and field mouse feeding over plant seeds (producer) for survival.
Hence, the correct option is A.
Answer:
could be either or, but the name of the shape is a double helix.
Explanation:
Answer:
B) expression of inappropriate gene products
Explanation:
Most of the cancers are caused when a normal gene that code for one or other proteins involved in the regulation of the cell cycle is mutated. The mutated gene may cause the production of the faulty gene products. For example, the overproduction of products of the protooncogene that push cells through the cell cycle leads to tumor formation. Likewise, when the tumor suppressor genes are not able to produce enough product to prevent progression through the cell cycle, cancer may develop.
Answer:
Accumulation flooding occurs because the ground is completely filled with water and there is no longer a zone of dry land.
Explanation:
Flood is the overflow of water on the land which is usually dry throughout the year. It occurs when more water comes in the river due to rainfall or breaking of dam. But mostly flood occurs, due to melting of ice on the poles because of global warming. Global warming refers to the increase in average temperature due to presence of greenhouse gases such as carbondioxode, methane and water vapors etc in the atmosphere.
