What is pollination? Identify three ways pollen can be transferred. How is cross-pollination different
Stells [14]

Answer:

The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization. It can be transferred by things that feed from what has pollen. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cell
Marrrta [24]

Answer:

M phase: 4.8 hr

Prophase: 2.4 hr

Prometaphase: 0.72 hr

Metaphase: 0.24 hr

Anaphase: 0.84 hr

Telophase: 0.6 hr

Explanation:

Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase,  Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:

M phase: 40/200 = 0.2 x 24 hr = 4.8 hr

Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr

Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr

Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr

Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr

Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr

Explain why some scientific theories are changed over time​
cluponka [151]

Answer:

A common misconception is that scientific theories are rudimentary ideas that will eventually graduate into scientific laws when enough data and evidence have been accumulated. A theory does not change into a scientific law with the accumulation of new or better evidence.
