Scientists often use the analogy of a tree to describe the history of life on Earth. All organisms alive today, including archaea, bacteria, and eukaryotes, can trace their development to the same common ancestor or set of ancestors, which forms the base of the tree. Which statement provides the strongest evidence for the conclusion that all living things share common ancestry?

a. All living things perform either cellular respiration or photosynthesis

b. All living things use DNA as a genetic code to transmit information

c. All living things have vestigial structures that are remnants of structures found in ancestral species.

d. All living things are made of cells with approximately the same composition, size, shape, and function

Answers

Answer 1

Answer:

B

Explanation:

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to discover history of a living organism and to produce proteins, which are the complex molecules that do most of the work in our bodies

Benefits of Biotech in NC
North Carolina is an attractive terrain for biotechnology firms—from 2001 to 2010, the state experienced the highest job growth rate (23.5%) of any of the top biotechnology states in the country. Since 2001, the popularity of NC as a biotech destination has resulted in the creation of more than 12,000 jobs in pharmaceuticals, research, testing and medical labs, agricultural feedstock and chemical industries. All have shown robust growth. Related image
Students in NC have more opportunities to enter the field of biotechnology after graduation than in most states thanks to two very important research centers. The North Carolina Research Center located in Kannapolis and Research Triangle Park near Raleigh, are very important to the NC economy. Both of these facilities bring in tax revenue to our state and offer job opportunities in many science-based fields of study. Image result for research triangle
More than 250 companies and 50,000 people with expertise in fields such as micro-electronics, telecommunications, biotechnology, chemicals, pharmaceuticals, and environmental sciences are located here in NC. Industries invest more than $300 million in Research & Development at the region’s universities each year – double the average R&D investment for innovation clusters elsewhere in the nation. Because of these centers, NC is a leader in biotechnology advances in agriculture, energy and medicine. Our state is home to some of the leading physicians, research scientists, biotechnologists, and agricultural scientists in the US.
Some of the key factors that make North Carolina attractive for the biotechnology industry include:
the presence of the pioneering North Carolina Biotechnology Center and Research Triangle Park have lead to financial incentives the state government has provided to companies such as Merck and Quintiles; and the educational programs developed at both the community college and university level to help firms fill openings with qualified local employees with knowledge and training in biotechnology.
Tax revenues increase because of the large number of developing careers in the field of biotechnology in North Carolina.
Biotechnology affects us in every area of our lives, our food, water, medicine and shelter, improving quality of life. When it comes to Biotechnology, nothing could be finer than to live in North Carolina!

Answers

Answer:

look at Explanation

Explanation:

North Carolina’s biotech industry is quickly expanding.

Within the state, there are more than 600 life science companies employing 61,000 people at an average salary exceeding $81,000 a year – which is nearly twice the state’s overall private sector wage, according to the North Carolina Biotechnology Center.

In total, life science companies and institutions in North Carolina generate $73 billion in economic activity, which is an increase of 23 percent in two years, and account for 228,259 direct and indirect jobs, says North Carolina Biotechnology Center.

Furthermore, while employment in the nation’s life science industry rose by 7.4 percent from 2001 to 2012, North Carolina’s grew at a surprising 31 percent, even with setbacks from the Great Recession of 2008.

Following closely behind California, North Carolina outpaced life science industry growth in other states, including Texas, New York, Massachusetts and Florida, between 2009-2012, according to the U.S. Bureau of Labor Statistics. In the chart below, North Carolina's life science industry grew 5.2% from 2009 to 2012. While California's life sciences industry increased even more at 5.5% during the same time period, other states such as Pennsylvania and New Jersey actually saw their life sciences sectors shrink by 7% and 7.3%, respectively.

15. Explain how each of the following creates electrical energy:
a.
Solar
Hydro
Tidal
Wind
OTEC
Biomass
Geothermal

Answers

Solar- technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.

Hydro- a hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity

Tidal- energy is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows, and turns into unusable electricity

Wind- turns the propeller like blades of a turbine around a rotor, which spins a generator, which creates electricity

OTEC- plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity

Biomass- is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity

Geothermal- power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity

A. oil spills from ocean drill sites
B. human cities and houses being built in their habitats
C. Global warming
D. introduced can toads which are out competing polar bears for food

Answers

What is standard deviation?

The standard deviation in statistics is a measurement of how much a group of data may vary or be dispersed. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean.

An average is one number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group. The average of the integers 2, 3, 4, 7, and 9 is, for instance, 5.

9. If the concentration of water inside a cell is lower then outside the cell, what will be the net
movement of water molecules be? *
(1 Point)
a) Into the cell.
b) Out of the cell.

Answers

Answer:

a) Into the cell.

Explanation:

The water molecules outside the cell would move into the cell until there is no net movement of water molecules. This process is known as osmosis.

Osmosis is the movement of molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane until the concentrations across the membrane are equal. That is, there is no net movement of molecules across the membrane.

A. There would be more solar energy reaching Earth.
B. There would be more ice on Earth's surface.
C. The oceans would contain more carbonic acid.
D. The atmosphere would contain more methane.

Answers

B more ice on the earths surface. Greenhouse gases don’t tend to block the solar energy, but trap the energy that radiates from the earths surface. Dissolved CO2 becomes carbonic acid. More CO2 results in more carbonic acid. Methane is one of the greenhouse gases.
