BIG BRAIN ANSWER:
Before Darwin, a naturalist named Jean-Babtiste Lamarck believed that the environment altered the shape of individuals and that these acquired changes were then inherited. Meanwhile, Charles Darwin was a naturalist on a ship called the HMS Beagle, and he discovered that the beak shape varies among finch species in the Galapagos Islands. He found that the beak of an ancestral species of finch had somehow been transported to these islands, and adapted over time to acquire different food sources that were available, causing variation, and that nature just selected for the most suitable beak shape and against less useful ones.

What is the direction of the 4 typhoon?
4 typhoon means a wind threat that has the high speed of wind can attack 118-184 km/h.
What is a typhoon and what is the direction of the typhoon?Typhoon is defined as a tropical cyclone with a maximum wind of 34 knots or higher. A tropical cyclone with a maximum wind of fewer than 34 knots is called a tropical depression. The difference between the two types of tropical cyclones is just if the maximum wind is less than or above the threshold of 34 knots.
Tropical cyclones (Typhoon ) form between 5 and 30 degrees North latitude that move toward the west. Sometimes the winds in the middle and upper levels of the atmosphere change and move the cyclone toward the north and northwest direction.
So we can conclude that a typhoon is a tropical cyclone that includes a maximum wind of 34 knots or maybe higher.

what happens to excess fatty acid and glycerol in the body
The liver prepares for storage in the subcutaneous tissue and other storage depots when excess fatty acid and glycerol are in the body.
Lipogenesis is the metabolic process of converting and storing fatty acid and glycerol are converted and stored in depots. When the energy level decreases they are converted back into fats and this process is called lipolysis.
The liver is responsible for fat metabolism and the amalgam of lipoproteins. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids, and glycerol. This process takes place in the cytoplasm.
Triglycerides are a type of lipid found in the blood. When you consume food the unused fatty acid or calories are stored in the form of triglycerides stored in fat cells. Excess of triglycerides can lead to hypertriglyceridemia.

People with antisocial personality disorder are often more difficult to treat than people with other types of personality disorders. Why do you think this is so?
Answer:
I think that the difficulty in dealing with a person suffering from antisocial personality disorder is due to their lack of remorse towards the bad things they can do, things that possibly exceed the ethics or judgment of the person who is going to treat them. In addition, their lack of discernment towards what is really right or wrong can cause serious confrontations or discord between the person who suffers from the disorder and others.
Explanation:
The antisocial personality disorder consists of the lack of understanding of good and evil, with which, the person can come to commit bad things without any remorse and even seeming something normal, which is why their dealings with a person who has an ethic Iron could be very complicated, unlike other disorders where the person may do bad things, but they are aware of the bad things they do and, therefore, they regret it and they could try a change in their behavior.

Two factors that could affect whether the fly population on the island is in Hardy-Weinberg equilibrium are mutation and selection.
The way in which these two factors would affect, if the population of flies on the island is in Hardy-Weinberg equilibrium would be:
Mutation is a process by which new alleles are introduced into a population, which can alter the distribution of alleles in the population. If a new allele is introduced that provides a fitness advantage, then it could cause the allele frequencies in the population to move away from the Hardy-Weinberg equilibrium.Selection is the process by which certain alleles become more or less common in a population due to their relative fitness advantages or disadvantages. If a particular allele provides a fitness advantage, then the frequency of that allele will increase in the population, causing the population to move away from the Hardy-Weinberg equilibrium. On the other hand, if a particular allele provides a fitness disadvantage, then its frequency will decrease, again causing the population to move away from the Hardy-Weinberg equilibrium.Learn more about Hardy Weinberg equilibrium:

Notch is a receptor protein displayed on the surface of certain cells in developing fruit fly embryos. Notch’s ligand is a membrane-bound protein called Delta that is displayed on the surface of adjacent cells. When Notch is activated by its ligand, the intracellular tail of the Notch protein becomes separated from the rest of the protein. This allows the intracellular tail to move to the cell’s nucleus and alter the expression of specific genes.
Which of the following statements best explains Delta’s role in regulating cell communication through the Notch signaling pathway?
A. Delta transmits a chemical signal to all the cells of a developing embryo.
B. Delta allows the cells of a developing embryo to communicate without making direct contact.
C. Delta restricts cell communication to short distances within a developing embryo.
D. Delta determines which cells in a developing embryo express the gene that encodes the Notch protein.
If Delta is displayed on the surface of adjacent cells, and when Notch is activated by its ligand, the intracellular tail of the Notch protein becomes separated from the rest of the protein and allows the intracellular tail to move to the cell’s nucleus and alter the expression of specific genes, then C. Delta restricts cell communication to short distances within a developing embryo best explains Delta’s role in regulating cell communication through the Notch signaling pathway.
