Answer:

Dramatic evolution within human genome may have been caused by malaria parasite. A genetic mutation that protects people from a common form of malaria spread like wildfire in sub-Saharan Africa about 42,000 years ago, according to a new study.

People develop sickle-cell disease, a condition in which the red blood cells are abnormally shaped, if they inherit two faulty copies of the gene for the oxygen-carrying protein haemoglobin. The faulty gene persists because even carrying one copy of it confers some resistance to malaria.05-May-2011

Explanation:

An evolutionary force, called balancing selection, appears to be responsible for maintaining defects in our DNA associated with diseases, such as sickle cell anemia, because the mutation's damaging effects might be offset — in a biological way of thinking — by its potential benefits.

If the consumption of carbohydrates lowers, then ATP production will likely remain the same as the cell can use other compounds that feed into the glycolysis and citric acid cycles. Option 4 is the correct answer.

The dietary carbohydrates, protein, and fat are broken down to produce energy. The body generally uses glucose, as it is the simplest source of energy. Less energy is used to break down the glucose for energy.

From lipids and proteins, energy can be derived too. Lipids such as saturated lipids need more energy to break down the covalent bond. To generate energy from the lipid, the body must expend more energy. A lipid molecule generally produces 9 kcal of energy, while a carbohydrate molecule produces 6 kcal.

If the carbohydrate level decreases, the body will use the lipids to produce ATP. ATP production will not stop in the absence of carbohydrate until the body has lipid as a reserve material.

Hence, Option 4 is the correct answer as ATP will produce from other source.

Statement(1) : The cells in the heart have specific receptors that allow for the intake of hormones.

Statement(4) : Thyroid hormones show their effect on the heart by means of specialized cells.

Hormones are chemicals that coordinate many bodily processes by sending information to your organs, skin, muscles, and other tissues through your blood. Your body receives these messages that instruct it when and what to do. Your life and health depend on hormones.

Your endocrine system is composed primarily of the glands and tissues that produce and secrete hormones. Numerous physiological functions are regulated by hormones.

The key hormone in charge of regulating how quickly your body's metabolism works is the thyroid hormone. Thyroid hormone is essential for baby brain development. Thyroid hormone is produced and released by your thyroid, a little gland in the shape of a butterfly that is tucked under the skin at the front of your neck. Your endocrine system contains it.

The network of glands in your body known as the endocrine system produces the hormones needed for cells to communicate with one another. They are in charge of practically every cell, organ, and bodily process. The endocrine system is made up of several glands.

The new land acquired in the exchange will have a different holding period than the stock because the holding period of an asset is generally determined by the original acquisition date of that specific asset. In the exchange, Edith is essentially swapping one asset (building and land) for another (land and stock). Therefore, the holding period of the new land will be based on the original acquisition date of the building and land, while the stock will retain its original holding period.

In general, the holding period of an asset is determined by the original acquisition date of that specific asset. When Edith exchanges her building and land for land and stock, the holding period of the new land will be based on the original acquisition date of the building and land she exchanged. This means that the new land will inherit the holding period from the building and land.

On the other hand, the stock acquired in the exchange will retain its original holding period. This is because the stock is considered a separate asset from the land and building. The stock's holding period will be calculated based on the original acquisition date of the stock, which is not affected by the exchange.

The difference in holding periods between the new land and the stock is due to the fact that they are separate assets with their own acquisition dates. The land's holding period is tied to the original acquisition of the building and land, while the stock's holding period remains unchanged.

In an exchange where Edith swaps her building and land for land and stock, the new land will have a different holding period than the stock. The land will assume the original acquisition date of the building and land, while the stock will retain its original acquisition date. Understanding the implications of holding periods is important for tax purposes and determining the applicable tax treatment when assets are exchanged or sold

The correct order of the steps involved in preparing a smear slide is:

b. Air Dry, Fix, Stain.

A smear slide is a method used to prepare cells for microscopic examination. The main goal of this technique is to spread cells evenly over a slide and preserve their morphology, so they can be easily visualized under a microscope. The steps involved in preparing a smear slide are as follows:

Step 1: Air Dry - The first step in preparing a smear slide is to air dry the cells. The sample is spread onto a clean and dry slide, which is then left to air dry for several minutes. This helps to preserve the shape of the cells and reduces the risk of them becoming distorted during the next steps.

Step 2: Fix - Once the cells have been air dried, they are fixed to the slide. Fixation is a process that preserves the cells and helps to stabilize their structure. Fixation is typically done using a solution of formalin or ethanol, which crosslinks the proteins in the cells, preventing them from breaking down.

Step 3: Stain - The final step in preparing a smear slide is to stain the cells. Staining helps to distinguish different structures within the cells and makes them easier to visualize under a microscope. There are many different staining methods that can be used, such as gram staining, differential staining, or fluorescence staining.

The process of evolution that involves a change in the DNA sequence that leads to evolutionary change is called a mutation.

A mutation is a sudden and lasting alteration in the DNA sequence that can influence genetic variation. Changes in the DNA sequence can influence phenotype, which may or may not have an effect on an organism's fitness. Mutations occur spontaneously, either from errors in DNA replication or from exposure to mutagenic agents. Mutations may happen in either coding or non-coding regions of the DNA, and they can be either silent or expressed.

Evolution is a natural process that results in the gradual change of inherited characteristics in populations over generations. It is the process of alteration in the inherited characteristics of species over successive generations. In other words, it is the process of gradual changes that happen to species over time as they adapt to their environments. It can be defined as a change in the gene frequency in a population over time.

The projected 2020 population of Cuda is approximately 11,304,508.

To calculate the projected 2020 population of Cuda, we need to take into account the birth rate, death rate, and net emigration rate.

Birth rate = 9.962/1000 people

Death rate = 9.146/1000 people

Net emigration rate = 1.212/1000 people

2019 population = 11.3 million

To calculate the population change due to births and deaths, we can use the following formula. Population change = (birth rate - death rate) × population

Population change = (9.962/1000 - 9.146/1000) × 11.3 million

Population change = 0.816/1000 × 11.3 million

Population change = 9,208 people

To calculate the net population change (including emigration), we need to subtract the emigration rate from the previous calculation. Net population change = Population change - (emigration rate × population)

Net population change = 9,208 - (1.212/1000 × 11.3 million)

Net population change = 9,208 - 13,716

Net population change = -4,508

Since the net population change is negative, this means that the population has decreased from 2019 to 2020. To calculate the projected 2020 population, we need to subtract the net population change from the 2019 population.

Projected 2020 population = 2019 population - net population change

Projected 2020 population = 11.3 million - (-4,508)

Projected 2020 population = 11.3 million + 4,508

The fractional saturation for hemoglobin is 0.8290 when the partial pressure of oxygen is 44 mm hg.

The fractional saturation for hemoglobin can be described as the ratio of the total hemoglobin which is oxygenated.

The fractional saturation for hemoglobin can be calculated by using the following formula;

FS = (partial pressure of oxygen)^n ÷ (partial pressure of oxygen at which hemoglobin is 50% saturated)^n + (partial pressure of oxygen)^n

Here n represents the hill coefficient

Substituting the values in this formula to determine the fractional saturation;

Fractional saturation = (44)³ / (26)³ + (44)³

Fractional saturation = 85,184 / 17,576 + 85,184

Fractional saturation = 85,184 / 102,760

Fractional saturation = 0.8290
