2
/
R
, so if you increase V and R at the same rate then power will increase. Note that with real incandescent light bulbs the resistance of the filament increases a lot from the bulb's "off" state to its "on" stage due to the fact that the resistance depends on temperature.

Which of the following best describes evidence from comparative biochemistry that supports the theory of evolution? (4 points)
Different mechanisms of reproduction exist within the same species.
Different metabolic pathways exist within the same species.
Different species have the same genetic code.
Different species have the same number of chromosomes.

Answers

Answer:

1. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.

2. Anabolism  & Catabolism

3. Nearly everybody has the same genetic code. Although the sequences of bases in their DNA (and thus in the messenger RNA that is made from their DNA) vary between species and even between individuals within a species, almost all of them use the same code.

4.Yes, two or more species can have the same number of chromosomes. ... There's much more to differentiating between species than number of chromosomes. For one example, there are proteins present on eggs which 'match up' with proteins on sperm, and these are very specific.

How does RNA polymerase determine which strand is the template/antisense strand?

Answers

Answer:

Although RNA polymerase must recognize sequences on the template strand, by convention we draw the DNA sequence and regulatory signals on the "mRNA-like" strand. (This makes it simpler to directly determine the sequence of the resulting RNA.) The upper strand of DNA is the "mRNA-like" strand.

how does energy cause global warming

Answers

Answer:

Global warming is caused primarily from putting too much carbon into the atmosphere when coal gas and oil are burned to generate electricity or to run our cars. These gases spread around the planet very fast, keeping the solar heat that would otherwise be radiated out into space!

Hope this helped

Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation and farming.

The environmental problems directly related to energy production and consumption include air pollution, climate change, water pollution, thermal pollution, and solid waste disposal. ... The emission of air pollutants from fossil fuel combustion is the major cause of urban air pollution

The Top 8 Causes of Global Warming

- Power Plants. Forty percent of U.S. carbon dioxide emissions stem from electricity production. ...

- Transportation. EPA reports state that thirty-three percent of U.S. emissions come from the transportation of people and goods.
