Biologists from all around the world will be employed in a range of contexts in the future, including university labs, research facilities, the pharmaceutical and food industries, agriculture, hospitals, and other areas.

Because biology is so essential to our own existence, there will also be jobs for those who are interested in influencing the direction of science in the future.

We'll develop vaccines to stop the spread of diseases, extending the average human lifespan. We will be able to stop global warming and save the planet's future.

Exciting medical developments are taking place, and in the future, we might be able to have our medications customized for us depending on our DNA and environment to ensure that we receive the best effective therapies.

We will be able to produce cleaner, greener energy that is more sustainable than fossil fuels by developing new biofuels from non-food crops, waste biomass, algae, and microorganisms.

We can therefore conclude that many aspects of human existence will improve as a result of biology in the future.

Ethology is a branch of biology that studies the animal behavior of species in their natural environment. This can be understood or approached under different circumstances, such as how a particular animal species behaves under

Endoplasmic reticulum is a membrane system forming a series of sacs in eukaryotic cells. It has many functions, including the synthesis and transport of proteins. There are two types of endoplasmic reticulum with different structures, as follows:

1) Rough endoplasmic reticulum - its sacs are convoluted but flat, contiguous with the nuclear membrane. Its outer surface is studded with ribosomes, which gives it the rough appearance.

2) Smooth endoplasmic reticulum - its sacs are tube-like structures and they are located near the cell periphery. Sometimes these tubules branch, forming a reticular network wit.

To determine the age of a rock, we depend on that the layers of sedimentation were observable, and separated one from the other.

Having this in mind, we can say that all of the outcrops being able to determine its age, are the ones in which we can appreciate those layers clearly, and not that where layers overlap ones with others.

To determine the possible blood types of the offspring you have to create a Punnet square crossing the genotypes of the parents.

The male parent has a blood type A, his genotype is AO, which means that his gametes can carry the alleles "A" or "O"

The female parent has a blood type B, his genotype is BO, which means that her gametes can carry the alleles "B" or "O"

Cross the alleles of the parents to determine the possible genotypes of their offspring:

The genotypes of the offspring and their phenotypes are:

AB → Blood type AB

AO → Blood type A

BO → Blood type B

OO → Blood type O

All of the given options are possible blood types of the offspring so the correct answer is All of these.

To answer this we need to remember the pH scale, as lower is the numbe the compound is more acid, mmeanwhile, if the number ishigher wweare talking of a base, it ranges from 10to 14, being l0 the most acid, 7 neutral and 14 strongest base. Also, we must not forget that the pH scale is on a logarithmic scale (base 10) which means that each level is 10 timeshhigherthatn the previous level, so if we have a 13 pH level we are talking of a very strong base, therefore, the correct answer is option e.

An absolute threshold is the smallest level of stimulus that can be detected, usually defined as at least half the time. The term is often used in neuroscience and experimental research and can be applied to any stimulus that can be detected by the human senses including sound, touch, taste, sight, and smell.

For example, in an experiment on sound detention, researchers may present a sound with varying levels of volume. The smallest level that a participant is able to hear is the absolute threshold.

However, it is important to note that at such low levels, participants may only detect the stimulus part of the time. Because of this, the absolute threshold is usually defined as the smallest level of a stimulus that a person is able to detect 50% of the time.

For hearing, the absolute threshold refers to the smallest level of a tone that can be detected by normal hearing when there are no other interfering sounds present. An example of this might be measured at what levels participants can detect the ticking sound of a clock.

Young children generally have a lower absolute threshold for sounds since the ability to detect sounds at the lowest and highest ranges tends to decrease with age.

For vision, the absolute threshold refers to the smallest level of light that a participant can detect. Determining the absolute threshold for vision might involve measuring the distance at which a participant can detect the presence of a candle flame in the dark.

For odors, the absolute threshold involves the smallest concentration that a participant is able to smell. An example of this would be to measure the smallest amount of perfume that a subject is able to smell in a large room.

The amount of force required for you to detect the feeling of a feather lightly brushing your arm is an example of the absolute threshold for touch. When it comes to touch, the level of stimulation required to detect the stimulus can vary dramatically depending upon the part of the body that is being touched.

Social inequality is typically thought of as the absence of result equality, but it may also be thought of as the absence of opportunity equality. Race, gender, class, and religion are interrelated identity characteristics that have an impact on many facets of life in the United States.

These social institutions might become more important at any point in a person's life, and everyone is affected by them.

Gender, on the other hand, is an identity that is independent of a person's biological sex. Girls and women are frequently expected to behave nicely, dress in stereotypically feminine ways, and provide for others. Typically, men are expected to be strong, brave, and competitive.

In society, class refers to the division of people into groups based on their socioeconomic circumstances. Based on variables like wealth, occupation, or education, the grouping is stratified. Therefore, it stands to reason that the higher classes are more powerful and influential than the lower classes.

Religion supports and encourages social conflict and inequity. It causes animosity and violence caused by religious differences and aids in persuading the impoverished to accept their position in life.

The shared and hereditary physical characteristics of a group are typically used to identify a person's race, making the definition of race complex.

As a result, it is clear that race, gender, class, and religion are interconnected identity qualities that influence many aspects of American life.

The number of chromosomes that will be in the resulting products of cellular division if the cell undergoes mitosis is 28 and 14 for meiosis.

Mitosis is the division of a cell nucleus in which the genome is copied and separated into two identical halves. It is normally followed by cell division.

Meiosis, on the other hand, is a cell division of a diploid cell into four haploid cells, which develop to produce gametes.

Mitosis is also called duplication division because the number of chromosomes in the parent cell does not change in the daughter cells. However, in meiosis, the chromosome number is reduced by half in the daughter cells.

According to this question, a diploid cell contains 14 pairs of chromosomes for a total of 2n = 28 chromosomes. This means that mitosis will result in 28 chromosomes while meiosis will result in 14 chromosomes.

- The larynx is a part of the respiratory system, it connects to the pharynx and the trachea, ait allows the air to pass from the throat through the trachea directly to the lungs.

It is in this structure where the vocal cords are found.

- The pharynx, also called throat, connects the mouth to the esophagus and also contributes to breathing and phonation because it connects the nasal cavity, the Eustachian tubes, and the larynx with the buccal cavity.

- The function of the sinuses is to increase the contact surface of the air with the epithelium of the nasal cavity, which allows it to humidify and warm the inhaled air. They also play a role in phonation.

These structures help reduce the relative mass of the skull, thus decreasing its weight, provide "shock resistance" in case of injury, and isolate sensitive structures from rapid temperature changes occurred during inhalation.

- The glottis is the space between the pharynx and larynx.

The only match that is incorrect is c. sinuses - remove dust particles
