Answer:
2. meiosis I only
Explanation:
During the zygotene stage of prophase-I of meiosis-I, homologous chromosomes synapse and are paired up. These paired homologous chromosomes are called bivalents. These paired homologous chromosomes align themselves at the equatorial plate of the cell during metaphase-I. Therefore, when observed through a microscope, cells are shown lined up two by two. During meiosis-II and mitosis, individual chromosomes with two sister chromatids are aligned at the cell's equator in metaphase.
Answer:
as I know
Explanation:
<em>Igneous rocks, which form from cooling magma or lava, and metamorphic rocks, which have been altered by heat and pressure, are unlikely to contain fossils. The “soft” tissues of an organism, such as skin, muscles, and internal organs are typically not preserved as fossils.</em>
Answer:
cooperation
Explanation:
Cooperation occurs when living things of different species work together to benefit themselves. The interaction between a bee and a flower is a symbiotic relationship. A symbiotic relationship between two living things is one in which at least one of the parties benefits. The relationship between the bee and the flower is a mutual one because both parties benefit.
While the pollen and nectar serve as food for the bees, the spread of the pollen to other plants assist in the reproduction process.
No. The recorded drop in water in the pipet of the potometer would have been used not only for plant transpiration, but also to return the plant cells to a turgid state. Turgid means to expand<span> due to high fluid content. Plants are required to maintain turgid cells to maintain an upright position as loss of turgidity results in plant wilting.</span>
Trees are a crucial part of the<span> carbon cycle</span>, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through <span>photosynthesis </span>in order to make energy. This carbon is then either transferred into oxygen and released into the air by <span>respiration </span>or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles andpollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.
