I would say either A or B
D. . They have contributed the same type of allele <span>for this gene.</span>
During mitosis, the <em />nuclear membrane breaks down and the duplicated chromosomes are separated and evenly distributed to opposite sides of the cell. Cytokinesis involves the division of the cytoplasm and the organelles that are contained within.
This describes the process of cell division. All of these events happen in the M phase of mitosis. The breaking down and fragmentation of the nuclear membrane to expose the genetic material is in the prophase. The next phase is the metaphase when the duplicated chromosomes align in a straight line (metaphase plate). Anaphase involves the separation of chromatids and by the time the chromatids reach the opposite side then the cell enters telophase. Lastly, cytokinesis involves restoration of the nuclear membrane, division of the cytoplasm, and production of two daughter cells.
<h2>The answer is:</h2>
Expansion and cracking
<h2>Explanation:</h2>
Whenever water freezes, it is expanded about 9 percent. Since the water in moist concrete freezes it producing pressure in the pores of the concrete. The collective effect of freeze-thaw cycles and disruption of aggregate can eventually cause expansion and cracking, scaling, and crumbling of the concrete that is formed from moist.
Answer:
Hi dude
This means farming that not only produces food, jobs and economic well-being, but also creates cultural, social and environmental benefits. Agroecology also protects and provides ecosystem services like pollination, natural pest control, nutrient and water cycling and erosion control.
Agro ecology is the future of farming
Farming for the Future is a holistic farming approach that starts with building and maintaining the soil, because healthy soil is better able to retain water, reducing irrigation and water usage, and soil erosion and loss of top soil are reduced.
Agroecological methods can also help farmers cope with climate change by enhancing resilience. Agroecology has the explicit goal of strengthening the sustainability of all parts of the food system, from the seed and the soil, to the table, including ecological knowledge, economic viability, and social justice.
