Answer:

False. The purpose of the Darwin Finch lab was to establish that the relationship between food sources and beak shape was food availability.

Explanation:

Finches speciation was due to geographical isolation on islands and the differences in their picks were an evolutive adaptation that reflected feeding habits. Their speciation depended on or was the result of their adaptation to the island and its characteristics. The finches´ beaks evolved according to food availability. Large beaks are better for islands with larger seeds, while pointed beaks are better for getting insects out of trees.

Suppose a large pizza is placed on earth, the moon, and Jupiter. In each location, the pizza weighs 2 N Which pizza would have t
Maurinko [17]

The correct answer is option A

The pizza on the Jupiter has the least mass as the weight of the pizza is  same,it will have the least mass in the planet with the highest gravity and Jupiter has the highest gravity.

Explanation:

The Moon's gravity is much less than the Earth's gravity. It is approximately one-sixth of the Earth's. The Jupiter gravity is much more intense than Earth's. It is approx 2.528 times more.

Hence, it is the Jupiter where the pizza will have least mass.

How the needs of a group of people may affect what scientists choose to study.
nignag [31]

Explanation:

It’s an important question because the road to a successful career in science – as with technology, engineering and mathematics, the other STEM fields – can be challenging, often requiring a Ph.D. or other postgraduate training. And once in their fields, there can be political and economic pressures with which to contend. The Bureau of Labor Statistics projects workforce shortfalls for many science fields, though the projected needs differ across the life, physical and natural sciences.

The energy acquired in photosynthesis is used to make glucose. Where is the glucose made in plants?
klio [65]

Explanation:

<u>in the stroma</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
  • This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
  • Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules in the stroma. These store energy in their bonds, which can be released in respiration in the mitochondria.
