The graph shows the results of a famous biological experiment. In the experiment, Kettlewell believed that the peppered moth demonstrated how environmental pressures influence evolution. He studied two areas. Birmingham was a rural wood, with natural conditions. Dorset was an urban, industrial area. The moths use tree trunks to camouflage themselves against birds, which are their major predators. Natural gene variations produce a light form of the peppered moth, and a dark form, meaning that they are not equally visible.
All BUT ONE statement is supported by Kettlewell's data. That is
Question options:
Dark moths had a survival disadvantage in industrial Dorset.
Light moths had a survival disadvantage in industrial Dorset.
Dark moths had a survival disadvantage in forested Birmingham.
Light moths had a survival advantage in forested Birmingham.
The statement not supported by Kettlewell's data is "Light moths had a survival disadvantage in industrial Dorset," while the other statements are supported by the experiment's results.
What statement is not supported by Kettlewell's data regarding the survival of peppered moths?The statement that Kettlewell's statistics does not support is: "Light moths had a survival disadvantage in industrial Dorset."Kettlewell's data showed that dark moths had a survival advantage in forested Birmingham, where the tree trunks were darkened by pollution, making the dark moths harder to spot by predators. In contrast, light moths had a survival advantage in forested Birmingham before industrialization when tree trunks were lighter in color.
In industrial Dorset, where pollution had darkened the tree trunks, Kettlewell found that dark moths had a survival advantage, as they were better camouflaged against the darker tree trunks. Light moths, on the other hand, had a survival disadvantage in industrial Dorset, as they were more visible to predators against the darkened tree trunks.
Therefore, all the statements except "Light moths had a survival disadvantage in industrial Dorset" are supported by Kettlewell's data.

Suppose in humans an autosomal gene, , causes dwarfism in one homozygous state (++) , normal height in the heterozygous state (+−) , and is embryonic lethal in the other homozygous state (−−) . A separate gene, , found on another chromsoome causes albinism, an autosomal recessive disorder. Albino individuals have the −− genotype. Rick and Lori, who are both heterozygous for both genes (+−+−) , just had a son, Carl. What is the probability that Carl is a dwarf with albinism?
Each chromosome in the undivided state is homozygous for any recessive allele, which equals 1 (3/4)3. = 37/64.
What is the likelihood that you are an albino carrier?This means that in order to be born with albinism, a kid must inherit two copies of the gene—one from each parent—from both parents. If both parents have the gene, their child has an odds of one in four of having colorblindness and a one in two probability of having the gene.
What is the likelihood that both kids are albinos?Everything depends on whether both you and your wife are albino. If neither of you have children, there is a one in four probability that one of them will be albino.

Energy flows in food webs according to the 10% rule, which states that only 10% of the energy stored as biomass in one level is transmitted to the following level.
How is energy transferred between organisms in a food web?
Food webs are interactions between different organisms involving transference of energy when some of them feed on the other ones. The ones placed at lower levels pass energy to the ones at the higher levels.
Energy flow occurs according to the 10% rule, which refers to the energy flow along the trophic chains from autotrophs to heterotrophs and detritivorous organisms.
Only 1% of the solar energy that reaches the Earth's surface is absorbed by autotroph organisms. From there, each trophic level transmits 10% of its energy to the following trophic level. The remaining 90% is lost to the environment as heat.
The 10% rule states that only about 10% of the energy stored as biomass at one trophic level per unit of time ends up as biomass at the next trophic level, in the same unit of time.

The biggest contributor to global warming is burning fossil fuels.
What is global warming ?Global warming is an increase in the average temperature of the Earth's atmosphere and oceans, caused by the emission of greenhouse gases such as carbon dioxide, methane, and water vapor. These gases trap heat in the atmosphere and cause the planet to become warmer. This process is known as the "greenhouse effect." Long-term climate change due to global warming is expected to cause changes in weather patterns, rising sea levels, changes in the amount and pattern of precipitation, and an expansion of deserts in the subtropics. It is also expected to cause increases in extreme weather events, such as heat waves, droughts, floods, and hurricanes.

The biggest contributor to global warming is burning fossil fuels.
Why burning fossil fuels is the biggest contributor to global warming?Burning fossil fuels is the biggest contributor to global warming because when we burn these fuels, we release large amounts of carbon dioxide and other greenhouse gases into the atmosphere. These gases trap heat from the sun and cause the Earth's temperature to increase, leading to global warming and climate change.
Fossil fuels are also the primary source of energy for transportation, industry, and electricity generation around the world. As the global population continues to grow and economies continue to develop, the demand for energy increases, leading to more burning of fossil fuels and more greenhouse gas emissions.
While deforestation, natural cycles, and increased solar radiation can also contribute to global warming, the burning of fossil fuels is the largest and most significant human-caused contributor.

Ventricular Systole
Diastole
Early Diastole
Ventricular Systole stage of contraction is this. Option C is correct answer.
Early ventricular diastole: What is it?Early ventricular diastole is characterised by the filling of the ventricles with blood from the atria, which begin to weakly contract (atrial systole) in late ventricular diastole and force additional blood flow. The left atrium is coloured pink, and the right atrium is coloured blue.
What are systole and early diastole?The cardiac cycle contains two phases: diastole and systole. As the heart beats, they take place as blood is pumped via a network of blood vessels to reach every region of the body. Diastole happens when the heart relaxes after contracting during systole, which happens when the heart contracts to push blood out.
