Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
Answer:
Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. ... But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.
Answer:
The genes that the child inherited from the parents is the SS gene
Explanation:
The genetic composition of the haemoglobin genotype is given by two gene variants; A which is dominant and S which is recessive. As such, an individual can be AA, AS or SS. Individuals that are AA and AS do not show traits of the disease, but SS individuals have sickle cell anaemia.
From this example, since both parents have no symptoms and their child have sickle cell, their genotypes most likely were AS and AS. Let me show you how:
A S
A AA AS
S AS SS
From the cross above, there is a 1 in 4 chance that if both parents were AS, their child will be SS. Any other composition from the parents will not produce an SS offspring. Hence the genes that the child inherited from the parents is the SS gene.
Answer:
The correct answer would be -
1. the ocean have
2. water
3. acidic.
Explanation:
Carbon dioxide fro the atmosphere dissolves in the seawater naturally. This process can be understood by the following process:
Water and carbon dioxide reacts to form carbonic acid that can dissociate into either carbonate ion or bicarbonate ion:
1. CO2 + H2O ====> H2CO3⁻ (carbonic acid)
2. H2CO3⁻ ======> H⁺ + HCO3⁻ (bicarbonate ion)
3. H2CO3⁻ ======> 2H⁺ + CO3⁻ (carbonate ion)
Due to the presence of proton ions in seawater, seawater becomes more acidic. As hydrogen ions bind to the carbonate ions to make bicarbonate ions, the carbonate ion reduced which is required to form the
Answer:
Plasma
Explanation:
We don't have the figure, but I think the answer is probably plasma.
Blood plasma is the fluid that blood cells are suspended in. When blood is spun at high speed, the cells separate away from the plasma into different layers because of their different weights and shapes.
Plasma is liquid portion of blood. It transports nutrients and wastes and maintains homeostasis.
