If E(X) = p, where E(X) is the expected value of X, then the estimator is impartial.
It's important to keep in mind that the expected value of X is determined by multiplying each potential outcome by the likelihood that it will occur, then adding up all of those values.
What we have here is that:
E(X1) = n1p1 (since we have n1 male smokers with each of them with probability p1 of smoking) (since we have n1 male smokers with each of them with probability p1 of smoking)
E(X2) = n2p2 (because we have n2 female smokers with each of them with probability p2 of smoking) (since we have n2 female smokers with each of them with probability p2 of smoking)
Therefore, we must demonstrate that (X1/n1)-(X2/n2) is an impartial estimator for p1-p2.
As a result, we must demonstrate (by definition) that
E(x1/n1)- E(x2/n2) = p1-p2
E(x) = E(x1/n1) - E(x2/n2)
E(x) = 1/n1 E(x1) - 1/n2 E(x2)
But we know that E(X1) = n1p1 and E(X2)=n2p2
=1/n1 E(x1) - 1/n2 E(x2)
= 1/n1 (n1)(p1) - 1/n2 (n2)(p2)
= p1 - p2
As a result, p1 - p2 = E(x1/n1)- E(x2/n2) and an unbiased estimator for p1 and p2 is (X1/n1) (X2/n2).

explain how climate change is impacting biodiversity in ecosystems. provide two examples
Climate change is causing alterations in temperatures, precipitation patterns and sea levels, which are negatively affecting biodiversity in ecosystems. For example, it is causing the loss of habitats for polar bears in the Arctic and coral reefs in tropical oceans.
Climate change refers to the long-term changes in the average weather patterns that have come to define Earth's local and regional climates.
These changes are primarily caused by increased levels of greenhouse gases in the atmosphere, which trap more heat from the sun and warm the planet. As a result, temperatures are rising, precipitation patterns are changing, and sea levels are rising.
All of these impacts are having a negative effect on biodiversity, or the variety of life, in ecosystems.
For example, the loss of sea ice in the Arctic due to warming temperatures is causing the loss of habitat for polar bears, which rely on the ice to hunt and breed. As sea ice disappears, so do the polar bears' food sources, making it more difficult for the population to survive.
Another example is the decline of coral reefs in tropical oceans. Coral reefs are some of the most biodiverse ecosystems on the planet, providing habitat for thousands of species of fish, crustaceans, and other marine life.
However, warming oceans and ocean acidification, caused by increased levels of carbon dioxide in the atmosphere, are causing coral reefs to bleach and die. This loss of coral reefs is having devastating effects on the species that depend on them for survival, leading to a decline in overall biodiversity in these ecosystems.

The events of thyroid hormone (TH) synthesis in the correct order are: 3,1,2,4.
The events of thyroid hormone (TH) synthesis in the correct order are: Iodine combines with thyroglobulin (TGB) to produce thyroid hormone precursors , Thyroid hormone precursors are internalized into follicular cells and stored in the colloid as TGB ,Follicular cells secrete TGB into a lysosome , Thyroid hormone precursors travel to a lysosome where they are cleaved from TGB and released into circulation as active thyroid hormone. Thyroid hormone is a hormone produced and secreted by the thyroid gland. It regulates many important functions in the body, including metabolism, growth and development, and body temperature. There are two main types of thyroid hormones: triiodothyronine (T3) and thyroxine (T4). These hormones play a critical role in maintaining overall health and well-being and are regulated by the hypothalamus and pituitary gland through a feedback system known as the hypothalamic-pituitary-thyroid (HPT) axis. Abnormal levels of thyroid hormone can lead to conditions such as hypothyroidism (low thyroid hormone levels) or hyperthyroidism (high thyroid hormone levels), which can cause a variety of symptoms and require medical treatment.

what are the first two fuel sources that the body uses during fasting?
The human body uses different sources of energy to function, and the primary source of energy during fasting is stored glucose and fat. Here is a detailed explanation of the first two fuel sources the body uses during fasting:
Glucose: Glucose is the primary source of energy for the body, especially the brain. It is stored in the liver and muscles as glycogen and can be rapidly converted to glucose as needed. During fasting, the body will first use up stored glucose as its primary energy source. This glucose is released into the bloodstream, where it can be used by the cells to produce energy.
Fat: Once the stored glucose has been depleted, the body will start to break down stored fat as its primary source of energy. Fat is stored in adipose tissue throughout the body and can be broken down into fatty acids and glycerol, which can be used as fuel for the cells. The breakdown of fat is a slower process than the breakdown of glucose, but it provides a more sustained source of energy.
In summary, during fasting, the body first uses up stored glucose as its primary energy source and then switches to breaking down stored fat as its primary source of energy.

The effect is zero water flow between the two solutions, even though the water is moving in both directions. In biology, some cells must be maintained in an isotonic solution to support cellular functions. Examples of isotonic solutions are blood cells, osmoconformers, and osmoregulation.
While a hypotonic solution is a solution that has a lower osmotic pressure than other solutions. This is because a hypotonic solution has a lower concentration of solutes than the concentration of solutes in other solutions, for example, saline solutions and intravenous fluids.

Caitlin's blue eye color indicates that she has two copies of the recessive allele for eye color, one from each parent.
Eye color is determined by multiple genes, and the brown eye color allele is dominant over the blue eye color allele.
If Caitlin's father has blue eyes, it means that he also has two copies of the recessive allele for blue eye color. This means that Caitlin's father must have received one blue allele from each parent.
If Caitlin's mother has brown eyes, it means that she has at least one dominant brown allele and one recessive blue allele. She could have two brown alleles, or one brown and one blue allele.

why don’t people with dmd make dystrophin?
Mutation of the DMD gene will result in absence of the dystrophin protein, leading to degeneration of muscle fibers. The body can replace (regenerate) some muscle fibers, but over time more and more muscle fiber is lost. Such degeneration leads to the symptoms and findings associated with DMD.
DMD occurs because the mutated DMD gene fails to produce virtually any functional dystrophin. Individuals with BMD genetic mutations make dystrophin that is partially functional, which protects their muscles from degenerating as badly or as quickly as in DMD.
Dystrophin is made by an X-chromosome gene, DMD is caused by mutations in the dystrophin gene. These mutations can cause dystrophin production to cease entirely or to produce a truncated, non-functional form of the protein.
It is a hereditary condition that inhibits dystrophin synthesis, a protein that is essential for muscle function. Dystrophin deficiency causes gradual muscle deterioration and weakening in people with DMD.
Muscles are vulnerable to injury and damage when dystrophin levels are low. This causes muscle weakness and atrophy over time, which can eventually impair the heart and breathing muscles. Dystrophin deficiency also impairs the proper functioning of the muscle cell membrane, making muscle cells more vulnerable to harm and increasing the chance of muscle degeneration.
In short, persons with DMD are unable to make dystrophin due to dystrophin gene mutations. This lack of dystrophin causes gradual muscle degeneration and weakening, making daily activities difficult for people with DMD and potentially leading to life-threatening problems.
