Answer:

It's either D or B, I'm not really sure

Explanation:

In 1972, EPA issued a cancellation order for DDT based on its adverse environmental effects, such as those to wildlife, as well as its potential human health risks. Since then, studies have continued, and a relationship between DDT exposure and reproductive effects in humans is suspected, based on studies in animals.

Human health effects from DDT at low environmental doses are unknown. Following exposure to high doses, human symptoms can include vomiting, tremors or shakiness, and seizures. Laboratory animal studies showed effects on the liver and reproduction. DDT is considered a possible human carcinogen.

Answer: There are a few types of atoms that can be a part of a plant one day, an animal the next day, and then travel downstream as a part of a river’s water the following day. These atoms can be a part of both living things like plants and animals, as well as non-living things like water, air, and even rocks. The same atoms are recycled over and over in different parts of the Earth. This type of cycle of atoms between living and non-living things is known as a biogeochemical cycle.

All of the atoms that are building blocks of living things are a part of biogeochemical cycles. The most common of these are the carbon and nitrogen cycles.

Tiny atoms of carbon and nitrogen are able to move around the planet through these cycles. For example, an atom of carbon is absorbed from the air into the ocean water where it is used by little floating plankton doing photosynthesis to get the nutrition they need. There is the possibility that this little carbon atom becomes part of the plankton’s skeleton, or a part of the skeleton of the larger animal that eats it, and then part of a sedimentary rock when the living things die and only bones are left behind. Carbon that is a part of rocks and fossil fuels like oil, coal, and natural gas may be held away from the rest of the carbon cycle for a long time. These long-term storage places are called “sinks”. When fossil fuels are burned, carbon that had been underground is sent into the air as carbon dioxide, a greenhouse gas.

Recently, people have been causing these biogeochemical cycles to change. When we cut down forests, make more factories, and drive more cars that burn fossil fuels, the way that carbon and nitrogen move around the Earth changes. These changes add more greenhouse gases in our atmosphere and this causes climate change.

The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.

Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.

Carbon moves through our planet over longer time scales as well. For example, over millions of years weathering of rocks on land can add carbon to surface water which eventually runs off to the ocean. Over long time scales, carbon is removed from seawater when the shells and bones of marine animals and plankton collect on the sea floor. These shells and bones are made of limestone, which contains carbon. When they are deposited on the sea floor, carbon is stored from the rest of the carbon cycle for some amount of time. The amount of limestone deposited in the ocean depends somewhat on the amount of warm, tropical, shallow oceans on the planet because this is where prolific limestone-producing organisms such as corals live. The carbon can be released back to the atmosphere if the limestone melts or is metamorphosed in a subduction zone.

The accuracy of the calculated cell concentration depends on the precision and reliability of the method used, as well as the proper interpretation of the data obtained.

The calculated cell concentration that is more accurate depends on the method used to calculate it. For example, if the cell concentration is determined using a hemocytometer, then counting the cells in multiple squares and averaging the results would provide a more accurate measurement.

On the other hand, if a spectrophotometer is used to measure the absorbance of a sample, then using the appropriate conversion factor to estimate the cell concentration would be more accurate.

In a reflex arc, motor neurons pass out of the central nervous system to stimulate effectors.

A reflex arc is a neural pathway that enables rapid and automatic responses to certain stimuli, ensuring quick and efficient reactions to protect the body from harm. This process consists of five main components: the receptor, sensory neuron, integration center, motor neuron, and effector.

Receptors detect the stimulus and generate an impulse that travels along the sensory neuron. This impulse then reaches the integration center, typically the spinal cord, where interneurons transmit the signal to the appropriate motor neuron. Motor neurons are responsible for carrying the signal away from the central nervous system and towards the effector, which is typically a muscle or gland. Effectors then respond accordingly, such as contracting a muscle to pull the hand away from a hot surface or releasing hormones to initiate a specific bodily response.

In summary, a reflex arc is a crucial mechanism in the nervous system that allows for quick and automatic responses to stimuli. Motor neurons play a vital role in this process, as they carry signals from the central nervous system to the effectors, initiating the necessary response.

TFH cells in the germinal center

Explanation:

The Tfh cells, present in the germinal center, are responsible for maturing and stimulating the class change of immunoglobulins (such as the change from IgM to IgE). This change could stimulate the new classes of immunoglobulins to act with stimulating antibodies to produce an immune response.

It is important to point out that the germinal center is the activated point of a lymphoid follicle that contains B and T lymphocytes, which act in the memory of the cells of the immune system.

In my puppy therapy experiment, the experimental unit is a section in the course.

Correct option is B.

There are six sections of the introductory biology course, each with twelve students assigned to it. The intervention we're testing—the introduction of puppies—is applied to multiple individual students at once, so I cannot use individual students as the experimental unit. Instead, I am testing whether puppies can reduce stress in each section taken as a whole.

For the sake of our experiment, the sections are divided into two groups; those who play with puppies for 15 minutes and those who do not. After the 15 minute period, we will measure the percentage of students in each 'experimental unit' (section) who report feeling 'very stressed' and compare the results. This allows us to determine if puppy therapy is an effective stress reducer for students overall.

Correct option is B.

The correct sentence regarding microscope care and handling is number 5: Store the microscope with the 40x objective in position, the cord wrapped and secured, and the power off.

Proper care and handling of a microscope are essential for maintaining its functionality and longevity. Out of the given sentences, number 5 is the correct statement.

Storing the microscope with the 40x objective in position is important because it helps protect the delicate lens and ensures that it remains properly aligned. It is recommended to store the microscope with the lowest-power objective (usually 4x or 10x) in place to avoid potential damage to higher magnification lenses.

Wrapping and securing the cord is crucial to prevent any tangling or damage to the power cord, which could impact the microscope's electrical connections and functioning.

Turning off the power when storing the microscope helps conserve energy and prevents any accidental usage or damage that could occur if the microscope is left powered on for an extended period.

Overall, following proper storage practices, such as keeping the 40x objective in position, securing the cord, and turning off the power, helps maintain the microscope's condition and ensures its readiness for future use.

Genes are located on many chromosomes. In other words, a particular section of the genome is located on each chromosome.

The primary function of the chromosomes is to transfer DNA, the fundamental component of genetic material. The genetic instructions for numerous biological functions are encoded in DNA.

Chromosomes, which resemble threads, are located in the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).

These processes are necessary for the development, maintenance, and procreation of the organisms. Proteins like histones, which protect the chromosomes.

Therefore, DNA is passed down from parents to children and contains the precise instructions that give each sort of living thing its individuality.

Eggs were found to evolve for over a billion years ago whereas chicken have been found to evolve around for just over 10,000 years. Thus, it can be concluded that eggs came first followed by the chicken.

Evolution can be defined as any net directional change or cumulative change in the characteristics or traits of an organism or populations over many generations in order to survive better in the surrounding environment.

Eggs come from chickens and chickens come from eggs. It is the ancient riddle. However, eggs are just the female sex cells which were supposed to have evolved more than a billion years ago, whereas chickens have been found to evolve around for just 10,000 years ago. Therefore, it can be said that the eggs have came first followed by chickens.
