Heart disease is the leading cause of death among both men and women in the United States.
It is usually caused when a sticky substance called plaque builds up in the arteries. Often, the
only symptoms of heart disease are chest pain or discomfort.
Why do you think heart disease is so prevalent in the United States? How could heart
disease affect other
organ systems?
Heart Diseases prevalent in the United States due to the leading causes of High blood pressure, a High Cholesterol level, diabetes, Overweight and obese, Alcohol overuse are the key factors.
Heart disease could affect other organs as if the heart is weak, blood could not be circulated and pumped properly thus fluid will start filling in kidneys, lungs, stomach, etc. cause swelling in ankles in feet or legs.
Coronary heart disease is most common cause of death, data suggests that over 20.1 million adults age 20 and older have CAD. CAD can occur when arteries that supply blood and oxygen to heart becomes clogged due to fatty materials called plague. Such factors results sudden Cardiac arrest.

choose all that are effects of insulin. multiple select question. stimulates glucose oxidation decrease cellular uptake of glucose inhibits gluconeogenesis stimulates glycogenesis inhibits lipogenesis
Insulin's effects include inhibiting gluconeogenesis, stimulating glycogenesis, and stimulating glucose oxidation.
The main effect of insulin is to lower blood sugar, but it also affects muscle and fat cells, causing those cells to store additional glucose that can't be used by cells.
Insulin resistance is a hallmark of type 2 diabetes, and insulin is a key hormone that inhibits gluconeogenesis.
Insulin helps to increase PPI substrate-specific activity on glycogen particles, which in turn stimulates the liver's synthesis of glycogen from glucose. PPI, on the other hand, accelerates glycogenesis by activating glycogen synthase B.
The primary activities that insulin has are to permit glucose to enter cells to be utilized as energy and to keep up with how much glucose is tracked down in the circulation system inside typical levels. The arrival of insulin is firmly controlled in solid individuals to adjust food consumption and the metabolic requirements of the body.

In a flock of sheep there are animals with brown fleece and brown eyes and others with white fleece and blue eyes. There are no animals with white fleece and brown eyes or with brown fleece and blue eyes. What can you conclude about the genes for fleece color and eye color
Answer:
In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby's eye color is determined by the parents' eye color and whether the parents' genes are dominant genes or recessive genes.
A lamb inherits 2 genes for color, one from each parent. This color gene causes the pigment named eumelanin to be produced in the cells of the wool follicles. This pigment produces the basic black or brown color of the Icelandic sheep.

How would the contractile vacuole of a freshwater amoeba respond if the organism was placed in seawater?a. with more contractionsb. with fewer contractionsc. the contractions would suddenly ceased. with the same frequency of contractions
If a freshwater amoeba is placed in seawater, the contractile vacuole would respond with more contractions. This is because seawater is more saline than freshwater and contains a higher concentration of ions. As a result, water would flow into the amoeba through osmosis, causing an increase in its internal volume. The contractile vacuole would then need to work harder to pump out the excess water and maintain the appropriate internal environment of the amoeba.
The contractile vacuole is an organelle that helps in regulating the water content and salt concentration of the cell. It works by collecting excess water from the cytoplasm and expelling it out of the cell through a pore. The frequency of contractions of the contractile vacuole depends on the concentration of water and salt in the surrounding environment. In freshwater, the contractile vacuole contracts less frequently as the concentration of water outside the cell is higher than inside the cell. However, in seawater, the concentration of salt outside the cell is higher than inside, and this would lead to an increased frequency of contractions of the contractile vacuole to remove excess water from the amoeba.

How did snakes initially lose their limbs (hint: this has to do with a mutation)?
First, we must understand that before limbless snakes, there was an ancestor that possessed limbs. In the population of this ancestor, a mutation occurred in one of the individuals that caused it not to develop limbs.
Currently, the data suggest that the loss of limbs was due to the Sonic hedgehog gene and the regulatory region of this gene, the ZRS region.
The mutation (a deletion or loss of nucleotides) in the regulatory region (ZRS) meant that the sonic hedgehog gene could not be expressed correctly and therefore the gene could not drive limb development.
We already know how the loss of limbs occurred, now the question is, how was this feature maintained over time?
Today, snakes do not have limbs because the limbless ancestor was able to reproduce in a great way and therefore its descendants have lasted until today. This was probably because the lack of limbs gave it an advantage and a greater survival compared to the other animals in the population that did have limbs.
Organisms without exonuclease activity would replicate somewhat faster than other organisms, since time would not be spent checking newly synthesized DNA and excising mismatched bases. The mutation rate would also be higher true or false
This is true that The mutation rate would also be higher.
What is mutation?A mutation is a change in the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA's genome. DNA or RNA can be found in the viral genome.
