How can plants contribute to chemical and mechanical weathering

Biology
1 answer:
aliya0001 [1]3 years ago
4 0

Answer:

The seed of a tree may sprout in soil that hasa collected in a cracked root. As the roots grow, they widen the crakcs, eventually breaking the rock into pieces. - mechanical weathering

Answer:

Gametes that will be produced are:

YST, YSt, YsT, Yst, yST, ySt, ysT, yst

Explanation:

From YySsTt, it is obvious that as there 3 type of genes.

The number of gametes = 2^{3} = 8

5 genes = 2^{5} = 32 genotypes

10 genes = 2^{10} = 1024 genotypes

20 genes = 2^{20} = 1048576 genotypes

Which words from the article help the reader to understand the importance of a special habitat?
Sliva [168]

Answer:

A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce. For a plant, a good habitat must provide the right combination of light, air, water, and soil.Jan 21, 2011

How can you test the idea that solar energy is required for the reduction of NADP+ to NADPH?
AysviL [449]

Answer:

In addition to biology, evidence drawn from many different disciplines, including chemistry, geology, and mathematics, supports models of the origin of life on Earth. In order to determine when the first forms of life likely formed, the rate of radioactive decay can be used to determine the age of the oldest rocks (see optional problems C and D, below) exposed on Earth’s surface. These are found to be approximately 3.5 billion years old. The age of rocks can be correlated to fossils of the earliest forms of life. A. The graph compares times of divergence from the last common ancestor based on the fossil record with a "molecular time" constructed by comparing sequences of conserved proteins to determine a mutation rate (after Hedges and Kumar, Trends in Genetics, 2003). Explain how such a molecular clock could be refined to infer time or the evolution of prokaryotes. B. Using a molecular clock constructed from 32 conserved proteins, Hedges and colleagues (Battistuzzi et al., BMC Evol. Biol. 2004) estimated the times during which key biological processes evolved. A diagram based on their work is shown. Connect the time of the origin of life inferred from this diagram with the age of the oldest fossil stromatolites and the age of the oldest exposed rock to show how evidence from different scientific disciplines provides support for the concept of evolution. Evaluate the legitimacy of claims drawn from these different disciplines (biology, geology, and mathematics) regarding the origin of life on Earth. The oldest known rocks are exposed at three locations: Greenland, Australia, and Swaziland. The following application of mathematical methods provides essential evidence of the minimum age of Earth.

Most cells fall within the range of 5-20 microns. What factors keep the size of the cell within these boundaries?
Tema [17]

Answer: Cytoplasm and organelles

Explanation:

Normally, a cell cannot attain a size greater than 20 microns due to the limits imposed by the size inter-relationships of its components. For example, there is a relationship between the amount of nuclear material and the size of a cell; this limits cells to a size where there is an optimal proportion of nuclear material to the rest of the cell.

Hope this helps :) and can I please get a brainly
