Answer:
The answer is C. DNA from the S bacteria is necessary for bacterial transformation to occur.
Explanation:
When heat-killed nonvirulent S bacteria will be treated with enzymes that degraded DNA it will destroy the genetic information required for cell survival. DNA is very essential for an organism and is called the molecule of life. DNA degradation is also a part of cell death called apoptosis. That's why all the samples grew except the one where DNA was enzymatically degraded.
The limitations in designing and building an eco-friendly home in Illinois will be climate constraints and social limitations.
<h3>What are eco-friendly homes?</h3>
Eco-friendly homes are homes which are designed such that they do not pose any danger to the envrionment.
Eco-friendly homes are compatible with the environment and make use of available environmental resources to design an environmental-friendly home.
The limitations in designing an eco-friendly home in Illinois will be:
- Climate constraints - due to hot climatic conditions
- Social constraints - due to its dense population
Therefore, the limitations in designing an eco-friendly home in Illinois will be climate constraints and social limitations.

Answer: These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.

Answer:
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive.
Stars start their lives as clouds of dust and gas. Gravity draws these clouds together. A small protostar forms, powered by the collapsing material. Protostars often form in densely packed clouds of gas and can be challenging to detect.
"Nature doesn't form stars in isolation," Mark Morris, of the University of California at Los Angeles (UCLS), said in a statement. "It forms them in clusters, out of natal clouds that collapse under their own gravity."
Smaller bodies — with less than 0.08 the sun's mass — cannot reach the stage of nuclear fusion at their core. Instead, they become brown dwarfs, stars that never ignite. But if the body has sufficient mass, the collapsing gas and dust burns hotter, eventually reaching temperatures sufficient to fuse hydrogen into helium. The star turns on and becomes a main sequence star, powered by hydrogen fusion. Fusion produces an outward pressure that balances with the inward pressure caused by gravity, stabilizing the star.
How long a main sequence star lives depends on how massive it is. A higher-mass star may have more material, but it burns through it faster due to higher core temperatures caused by greater gravitational forces. While the sun will spend about 10 billion years on the main sequence, a star 10 times as massive will stick around for only 20 million years. A red dwarf, which is half as massive as the sun, can last 80 to 100 billion years, which is far longer than the universe's age of 13.8 billion years. (This long lifetime is one reason red dwarfs are considered to be good sources for planets hosting life, because they are stable for such a long time.)

Answer:
1/1024 is the proportion of the F2 genotypes will be recessive for all five loci
Explanation:
When crossing between both parents, all genotypes will give us 100% AaBcCcDdEe. When a self-fertilization is performed this means that it can have a cross for example of two flowers of the same plant with the genotype AaBcCcDdEe In this way, given the law of independent segregation which states that the alleles of two or more different genes are distributed in the gametes independently of each other. The proportion that at this junction the alleles are aa (1/4) bb (1/4) cc (1/4) dd (1/4) and ee (1/4). The proportions (1/4)* (1/4)*(1/4)*(1/4)*(1/4) are multiplied, obtaining a value of 1/1024
