Answer:

Environmental law, also considered as the environmental and natural resources law, is a collective solution to environmental pollution. An associated but different array of regulatory regimes, now strongly affected by the environmental legal values, aims at the administration of the particular natural resources like minerals, fisheries, or forests.  

The environmental laws safeguard the safety and health of the environments and humans. For example, the Marine Research, Protection, and Sanctuaries Act prevent discarding of waste in the United States ocean waters without authorization, and the Clean Air Act restricts the emissions of pollutants.

The net energy yield from this pathway, where glucose is broken down through several steps forming pyruvate, is ________ molecul
stepan [7]

Answer:

2 molecules of ATP and 2 molecules of NADH

Explanation:

Glycolysis is the first step of cellular respiration (break down of glucose to extract energy) which occurs in the cytoplasm. Glycolysis is a pathway common to all living organisms- prokaryotes and eukaryotes, as it does not require oxygen to occur.

Glycolysis occurs in two major phases (ten steps) requiring 10 enzymes catalyzing each step; the energy-requiring phase and the energy-requiring phase.

In the energy-requiring phase, the starting molecule (glucose) gets rearranged in a series of chemical reactions, and two phosphate groups gets attached to it producing fructose-1,6-bisphosphate which is unstable, This modified sugar then splits in half due to its instability to form two different but inter-convertible phosphate-bearing three-carbon sugars (Dihydroxyacetonephosphate, DHAP and Glyceraldehyde-3-phosphate, G3P). Because the phosphates used in these steps come from 2 ATP molecules, 2 ATP molecules get used up in this phase

All the DHAP molecules get converted to G-3-P in order to enter the next phase.

In the energy-recovering phase, the 3-carbon sugar (G3P) is converted into another three-carbon molecule called pyruvate, through a series of reactions. In these reactions, two ATP and 1 NADH molecules are made. This recovery phase occurs twice (one for each of the two isomeric three-carbon sugars, DHAP and G3P). Hence, a total of 4 ATP and 2 NADH molecules are produced in this phase.

Overall, Glycolysis converts one glucose (six-carbon) molecule to two pyruvate (three-carbon) molecules and a net release of 2 ATP molecules (4 overall - 2 used) and 2 NADH molecules.

Bengal Tigers (Panthera tigris tigris) have coat colors that are either golden (the dominant trait) or white. In examining a pop
Hoochie [10]

Answer:

5%

Explanation:

Frequency of white tigers = 4%

population of tigers = 200

number of heterozygotes = 10

<u>Determine the actual genotype frequency of Heterozygotes </u>

frequency of heterozygotes = Number of heterozygotes / population

= ( 10 / 200 ) * 100

= 0.05 * 100 = 5%

Analyze and evaluate the formation of organic carbon molecules in c4 plants.
Setler [38]

In C4 plants, photosynthesis is compartmentalized into two; light-dependent stage and  light independent stage. The light-dependent stage occurs in the mesophyll cells of the leaf. Here, CO2 is fixed into oxaloacetate by PEP carboxylase enzyme. The oxaloacetate is then converted to malate that is then transported to bundle-sheath cells (around the leaf veins). The CO2 is then released from the malate and the gas molecule is subsequently fixed by RuBiSCO like in C3 plants. The biggest advantage of C4 photosytheis is that the wasteful process of photorespiration is greatly reduced.

Setler [38]

An experiment to test the best conditions for bacteria to grow is the material that the bacteria feed upon. <u>Option D.</u>

<u />

Antibacterial hand soap with different concentrations. Dependent variable bacterial growth as measured by the diameter of the zone of inhibition. Exposing Petri dishes to different temperatures can skew the level of bacterial growth they inhabit. Plant height is the dependent variable that responds to changes in the independent variable.

Sunlight is the controlling variable because each plant is exposed to the same amount of sunlight. It is the dependent variable because it measures the amount of plant growth. The dependent variable depends on the independent variable. How much plants grow depends on how much sun they receive. A continuous increase in temperature from a minimum value increases the rate of bacterial growth because the rate of metabolic reactions increases with increasing temperature.
