Explanation:

The salivary amylase does not function once it reaches the stomach after the good from mouth is passed to it.

Salivary amylase is an enzyme that breaks down carbohydrates right in the mouth. When it is passed to the stomach, the acidic ph of stomach denatures this enzymes and causes it to change it's shape. Consequently, the enzyme stops functioning.

Like most other enzymes, salivary amylase is a protein. At a pH between 6.5 and 7.0, it operates most effectively. More acidic or basic environments result in altered protein folding, which reduces the enzyme activity of the molecule.

The stomach's pH is typically between 1.0 and 2.0, which is very acidic. Salivary amylase's protein structure denatures and changes form at this pH level. As a result, when salivary amylase reaches the stomach, it is inactive.

Explanation:

We would expect 20 square meters of crystal coral coverage for an area of reef totaling 100 square meters, assuming that the percent of crystal coral coverage in 2007 remained constant for the entire reef.

Assuming that the percent of crystal coral coverage in 2007 remained constant for the entire reef, we can use the given percentage to calculate the expected coverage in square meters for an area of reef totaling 100 square meters. Let's say that the percent of crystal coral coverage in 2007 was 20%.

To calculate the expected crystal coral coverage, we first convert the percentage to a decimal:

20% = 0.20.

Then, we multiply this decimal by the total area of the reef (100 square meters):

Expected crystal coral coverage = 0.20 x 100 square meters

= 20 square meters.

Answer:

Dr. Gey's use of Henrietta Lack's cells after 24 years was not unethical due to his effort to figure out what was wrong with cells and why it happened to Henrietta.

Even if he did his intentions were to figure out how to treat cancer and help many people from the lethal condition. His effort made it possible to grown immortal human cells in culture. That help in developing the polio vaccine, and many other milestones.

For sperm produced by mosses and ferns to reach a(n) _archegonium_ they must swim through a film of water.

The female reproductive system of ferns and mosses is the archegonium. Some gymnosperms, like cycads and conifers, also have archegoniums. It is a flask-shaped structure made up of an egg-containing venter and a neck with one or more layers of cells.

As the archegonium develops, the neck-canal cells, which are positioned above the egg, vanish, creating a space for the sperm to enter. The antheridium, the analogous male reproductive organ, produces the sperm.

The female egg is contained in the archegonium, which also acts as the location where the egg and sperm are fertilized.

In Exercise 11.10, the expected value of the number of butterflies found by Alice, Bob, and Charlotte is obtained by finding the expected value of the sum of three indicator random variables.

In Exercise 11.16, the expected value of the number of flips needed to get the second head in a coin flipping experiment is determined. These exercises involve different scenarios of sampling with and without replacement.

In Exercise 11.10, the expected value of X, the total number of butterflies found, is found by calculating the expected value of each indicator random variable (X1, X2, X3) representing whether Alice, Bob, and Charlotte found a butterfly, respectively.

The expected value of each indicator variable can be obtained by multiplying the probability of success (finding a butterfly) by 1 and the probability of failure (not finding a butterfly) by 0. Then, the expected value of X is calculated as the sum of the expected values of the indicator variables.

In Exercise 11.16, the expected value of X, the number of flips needed to get the second head, is determined. To find this value, we first need to find the expected value of getting the first head. This scenario is similar to Example 11.11, which involves sampling with replacement.

Each coin flip is an independent event, and the probability of getting a head is constant at 0.5.

Therefore, the expected value of getting the first head is 1/p, where p is the probability of success (0.5 in this case).

In Exercise 11.17 (a), the scenario of waiting for a favorite song in Michael's iTunes playlist involves sampling without replacement. Each song played is not replayed, and there is only one favorite song among the total number of songs.

Therefore, this scenario is similar to Example 11.10, sampling without replacement.

To find the expected number of songs Michael needs to listen to until his favorite song comes up, the formula for sampling without replacement is used, which is the reciprocal of the probability of selecting the favorite song at each step.

Answer:

Cardiac, smooth, and skeletal muscle tissues.

Explanation:

Muscle tissue is classified into three types: cardiac, smooth, and skeletal. Cardiac muscle cells are found in the heart's walls, are striped (striated), and are under involuntary control. Except for the heart, smooth muscle fibers are found in the walls of hollow visceral organs (such as the liver, pancreas, and intestines), are spindle-shaped, and are similarly under involuntary control. Skeletal muscle fibers are found in muscles that are connected to the bones. They have a striated look and are controlled voluntarily.

Pasteur's swan-neck flask experiment proved that spontaneous generation was false.

An experiment is a technique used to verify or disprove a theory, as well as assess the likelihood or effectiveness of something that has never been tried before. By showing what happens when a certain element is modified, experiments shed light on cause-and-effect relationships. The purpose and scope of experiments vary widely, but they all rely on a repeatable process and logical analysis of the outcomes. Additionally, there are research conducted through natural experimentation.

While teams of professionals may spend years conducting methodical research to increase their grasp of a phenomenon, a toddler may conduct simple experiments to discover how objects fall to the ground.

When an animal's diet offers enough food to avoid malnutrition as well as an energy intake of around 70% of normal, the life-extending effects of energy restriction becomes apparent.

A dietary plan known as calorie restriction (also known as energy restriction or calorie restriction) lowers the amount of energy that is consumed from caloric foods and beverages without causing malnutrition. In addition to increased weight loss, severe calorie restriction also caused more bone loss. Although severe caloric restriction (800 kcal/day) is helpful for weight loss, its usage has been restricted because to documented adverse effects (such as hair loss and exhaustion). A unique kind of diet known as intermittent energy restrictions (IER) involves taking periodic breaks from eating food. Alternate-day fasting (ADF) & time-restricted eating are two examples of the various types of IER diets (TRF). The IER diet is regarded as an efficient way to lose weight in the literature.

Important characteristics of antimicrobic drugs include d. All of these choices are correct.

Antimicrobic are drugs used to kill or inhibit the growth of microbes or microorganisms such as bacteria, fungi, viruses or parasites. Antimicrobial drugs work by inhibiting the synthesis of the microbial cell wall.

Types of antimicrobials are antibiotics, antivirals, antifungals, or antiparasitics.

An important characteristic of antimicrobic drugs is that they are easily delivered to sites of infection to inhibit microbial growth, and will remain active in tissues and body fluids. However, antimicrobial drugs have relatively little toxicity to humans or do not cause side effects and have high toxicity to microbial cells. So this drug effectively kills microbes and is safe for humans.
