<span>During the peak of industrialization, there was a drastic change in the environment in Europe. Due to increased use of fossil fuels to run machines, the environment in urban centers was black due to soot produced by industries and settled on buildings and the environment. Therefore black moths were able to camouflage in this environment hence evade predators. White moths were, conversely, more conspicuous in this environment hence predated on more. The black moths were, therefore, more likely to pass their genes to the next generation compared to white moths</span>
For a recessive trait to be expressed in a generation of offspring, an individual must be Homozygous for the allele

Answer:
Atmospheric carbon dioxide is the raw material for photosynthesis, which plants rely on for producing sugars and other organic compounds.
Explanation:
The most accurate statement that supports the researcher's claim is that atmospheric carbon dioxide is the raw material for photosynthesis.
Photosynthesis is the process by which green plants manufactures their food in the presence of carbon dioxide and water using sunlight.
The product is usually glucose and oxygen.
The chemical equation is shown below;
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This raw material is a by-product of cellular respiration in human beings. Other process also releases carbon dioxide. Green plants uses this organic material to manufacture its food through photosynthesis.
We can attribute the increased growth rate in plants to the proliferation of the gases in the atmosphere.
Answer:
STRESS TEST
SYSTOLE
DIASTOLE
Explanation:
A standard exercise stress test employs an EKG (electrocardiogram) to watch closely any variation in the heart's electrical activity, the heart valves, the activities of the heart muscle, if the heart does not have shortage of blood flow during exercise and to study how heart functions when undergoing physical activity.
Diastole and systole are two levels of the cardiac cycle. They are seen during heart beats function as it pumps blood using a collection of blood vessels that transports blood to each and every singular part of the body. Systole is produced during contraction of the heart to pump blood out, and diastole is produced during relaxation of the heart when it contracts.
Let's consider, 120/80 mm Hg. The up figure stands for the level of pressure in the arteries when the heart muscle contracts --- systolic pressure. The below figure stands for blood pressure as seen when the heart muscle is between beats--- diastolic pressure.
