How would life on Earth be affected if water was less dense than ice?

Answers

Answer 1

Answer:

freeze and sink over and over until the entire lake was frozen.

Explanation:

This would eliminate many aquatic organisms and produce a system with far fewer life forms in lakes which freeze periodically.

which type of microscopy allows us to clearly view the internal contents of cell structures smaller than 200 nm?

Answers

Answer:  Electron Microscopy

Explanation:

Because the cell structures are so small, to clearly view them, requires a microscope that has a higher power of magnification than light microscopes can prove. This is usually an Electron Microscope.

Electron microscopy (EM) is a technique used to obtain high-resolution images of biological and non-biological specimens. It is often used to investigate the detailed structure of tissues, cells, organelles, and macromolecular complexes. (UMass Chan Med School Website)

how can different amino acids affect secondary structure

Answers

Answer:

Exposure to positively charged amino acids (arginine and lysine) is found to clearly stabilize the secondary structure. Kinetically, each amino acid promotes folding by generating a large increase in the folding rate with little change in the unfolding rate.

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

Answers

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.

Linnaeus' classification of life only included two categories: animals and plants. Which three kingdoms did he leave out? ( point)
O Insecta, Fungi, and Monera
O Monera, Bacteria, and Protista
O Fungi, Monera, and Protista
O Bacteria, Insecta, and Protista

Answers

Answer:

C

Explanation:

These are the three missing kingdoms

Fungi, Monera, and Protista are the three kingdoms he neglected to mention.

What Linnaeus classification?The Linnaean system is based on similarities in apparent physical qualities. This system is a hierarchy of taxa, from the kingdom to the species. Each species is given a unique two-word Latin name. The domain, which was just added and is a larger taxon, is smaller than the kingdom. Seven levels make up Linnaeus' hierarchical classification scheme. They are kingdom, phylum, class, order, family, genus, and species, in order of largest to smallest. Linnaeus created a hierarchy for nature in Systema Naturae. He suggested that the entirety of nature may be divided into three big categories known as kingdoms. Animals, plants, and minerals made up these three kingdoms. He categorizes each of these kingdoms.
