Answer:
Punnet squares for maximum white mice are above, but H e t e r ozygous white mice aren't possible if black is dominant. Because black will be expressed, rather than white.
If white can be dominant and black can be recessive then h e t e r ozygous white mice are possible. (Punnet squares for this situation are also attached)
They are a flat worm
they reproduce sexually
they have eyespots
Answer:
The frozen ground does not allow roots for large trees to grow
Explanation: characteristic of *severe cold climate regions* *especially treeless artic regions* and high mountain tops. Plant life must adapt itself to a *short growing season(e.g,shrubs and low lying plants adapt themselves to short growing season)* of about 60 days and to a soil that remain frozen for most of the year. Most tundra regions are covered with bogs, marshes, ponds and a spongy mat of decayed vegetation, although high tundras may be covered with only lichens and grasses. Vegetation of dwarf woody plants, grasses, sedges and lichens may be quite profuse in tundra despite the thin soil and short growing season.
Therefore, large trees cannot allow roots for large trees to grow in frozen ground but short shrubs and low lying plants can,to an extent .
Answer: When an organism is covered by sediment, it begins to decay. When decaying, the organisms release a gas. This process in turns leaves a thin film of carbon that preserves parts of the organisms.
Explanation:
Answer:
This is because must of the cell must be in INTERPHASE.
Explanation:
The onion root tip is the growing part of the onion and many cells in it undergo mitosis. In the lab, it is prepared in a way that the cells become flat on the microscope slide so that you can observed them well.
In the cell cycle, most of the onions root tip cells are in interphase, they spend most of their life in interphase. In interphase, there is no observable changes in the celks, the cells keep on growing and the nucleus is been duplicated. This is because most of the onion root cells spend most of their time reproducing and growing in the interphase stage. During the interphase, the cells can still be seen in dark spots because the nucleus is still present and prophase has not started yet.
