Option 3 is Correct. When natural selection favors two or more extreme phenotypes that each have a distinct advantage, this process is known as 'diversifying' or 'disruptive selection,' which increases genetic diversity.

Natural selection that favors phenotypic extremes is known as disruptive selection. This indicates that intermediates are the target of active selection. In contrast to stabilizing selection, it promotes genetic variety. When conditions favor individuals at both ends of a phenotypic spectrum over those with intermediate traits, this is known as disruptive selection.

The average phenotype of the trait is minimized and the two extreme phenotypes of the trait are favored by disruptive selection (diversifying selection). Disruptive selection is therefore the reverse of stabilizing selection in the result since it leads to a bimodal distribution of a characteristic in the population.

There are several security implementations that use biometrics. Biometrics involves using unique biological characteristics, such as fingerprints, facial recognition, or voice recognition, to identify and authenticate individuals. Two security implementations that use biometrics are:

1. Biometric access control systems - These systems use biometric technology to control access to secure areas or facilities. Instead of relying on traditional methods of identification such as key cards or passwords, biometric access control systems use unique biological traits to verify a person's identity and grant them access. For example, a company may use fingerprint scanners or facial recognition technology to ensure only authorized personnel can access restricted areas.

2. Biometric authentication for mobile devices - Many modern smartphones and tablets are equipped with biometric authentication features such as fingerprint scanners or facial recognition technology. These features allow users to unlock their devices and access sensitive data quickly and easily, without the need for passwords or PINs. Biometric authentication for mobile devices can also be used to authenticate mobile payments or authorize transactions, adding an extra layer of security to mobile banking and e-commerce.

In summary, biometrics is an increasingly popular security implementation that is used in various contexts, including access control and mobile device authentication.

Dextrose and fructose are both types of sugar. the sugar with the best flavor. plenty of whole grains. the starch. called milk sugar.

It is also found naturally in other plant foods such as honey, sugar beets, sugar cane, and vegetables.  Fructose is the  sweetest naturally occurring carbohydrate, 1.2 to 1.8 times more  sweeter than sucrose (table sugar). is the sweetness of Fructose metabolism does not require insulin and has little effect on blood sugar levels.  There are many different types of sugar, some  more common than others. Fructose, like glucose, is a type of sugar known as a simple sugar or "simple sugar". Monosaccharides can be combined to form disaccharides, the most common of which is sucrose, or "sugar." Sucrose is made up of 50% fructose and 50% glucose. Fructose and glucose have the same chemical formula (C6H12O6), but due to their different molecular structures,  fructose is 1.2 to 1.8 times sweeter than sucrose. In fact, fructose is the sweetest natural carbohydrate.

Answer:

Photosynthesis is a chemical reaction where plants take in carbon dioxide (CO2) and water (H2O) through its stomata. With the help of sunlight and chlorophyll, which is found in its chloroplast, it is used to produce glucose (C6H12O6) and oxygen (O2). It converts light energy (sunlight) to chemical energy.

Explanation:

Answer:

please mark me brainlest!!

Explanation:

photosynthesis, plants take in carbon dioxide  and water from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and conversion of CO2 into carbohydrates (carbon fixation).

Answer:

When the birth rate and the death rate remain the same, the population size does not change.

When the death rate exceeds the birth rate, the population shrinks.

Explanation:

essentially, the scenario is saying if the population stays the same (as in, the only things that change the population are death rate and birth rate changing)

these two concept's effects are inverse--the effect of death going up is the same effect as birth going down

so, if the death rate (- population) exceeds birthrate (+ population),

[-] > [+]

the population will logically shrink

when the birth rate (+ population) and the death rate (- population) are the same,

[+] = [-]

the population will logically stay the same

The population size will be significantly impacted by the birth rate and the mortality rate in the absence of immigration or emigration. The population will keep growing if both the birth and death rates stay constant.

This is because more people are added to the population than are eliminated since the birth rate is higher than the mortality rate. On the other hand, if more people die than are born, the population would decrease.

This is because more people are eliminated from the population than are added since the mortality rate is higher than the birth rate. In any case, the population size won't change if the birth and death rates stay the same.change.

This is due to the fact that there is a net change of zero since the number of people who are being added to the population is equal to the number of people who are being withdrawn from it. Accordingly, if both the birth rate and the death rate stay the same, the population size will not change.

Overall, the birth rate and the mortality rate will have a sizable impact on the population size when there is no immigration or emigration. The population will keep growing if both the birth and death rates stay constant. The population will, however, decrease if the death rate is higher than the birth rate. Furthermore, if both the birth and death rates stay the same, the population.

Extracting natural gas from underground is easier compared to coal, because of the following reasons:

1. Natural gas is trapped together with oil under a rock layer, when the drilling is finished, the natural gas comes out easily.

2. Natural gas is extracted from subsurface rock formations via drilling.

Also, natural gas is cleaner than coal because of the following reasons:

1. Natural gas emits almost 50% less CO2 than coal.

2. Natural gas can be released with drilling and fracturing. Vertical and horizontal drilling do not have that big effect on the eco-systems.

3. Coal-fired power plants emit not only carbon dioxide: other toxic gases impact people's health condition, these gases can lead to asthma or even to heart attack. Burning coal also comes with No and SO2 emissions, and these are linked to health problems such as asthma, lung cancer, and heart disease.

Natural gas has been proven to be cleaner than coal based on studies and emissions tests. According to the Worldwatch Institute, natural gas creates 47 percent less greenhouse gas emissions than coal does.

This fact is so significant that in the majority of global businesses, natural gas is now officially employed more frequently than coal. It burns more cleanly than coal and has significantly lessened the greenhouse impact, a problem for the environment.

Most people picture unclean people digging underground in dangerous conditions when the idea of generating and collecting coal is mentioned. This may not always be incorrect. Coal can be obtained by surface- or underground-level mining operations. Although these techniques work, the enormous equipment that is employed in the process adds to the environmental issues.

However, with the extraction of natural gas, production facilities now have access to items like fuel genies and natural gas compressors. Since these devices were made with the environment in mind, they aid workers in making their efforts successful and environmentally beneficial.

The structure of the STN (subthalamic nucleus) suggests that the most likely mechanism for its entry into the cell is through an ion channel.

The STN is a small nucleus located deep within the brain and is involved in several important functions such as motor control and decision-making. Its structure includes several ion channels that allow for the passage of ions such as potassium and sodium across the cell membrane.

Active transport and receptor-mediated endocytosis are less likely mechanisms for STN entry into the cell. Active transport requires the use of energy to move molecules or ions across the cell membrane, which is unlikely to occur with the STN due to its small size. Receptor-mediated endocytosis involves the binding of a ligand to a receptor on the cell membrane, followed by internalization into the cell. However, the STN lacks the necessary receptors for this process to occur.

In contrast, the STN's structure suggests that it is capable of diffusion directly through the membrane via ion channels. This is supported by studies that have shown the presence of several ion channels in the STN, including calcium and potassium channels, which are known to play a critical role in regulating neuronal excitability and synaptic transmission. Therefore, the most likely mechanism for the entry of STN into the cell is through the diffusion of ions via ion channels.
