What are proteins made from?
A. Nucleic acids.
B. Fatty acids.
C. Amino acids.
D. Monosaccharides
Please help!
Amino acid building blocks make up proteins. Thus, the right response to the question is (c).
How do proteins become made?A complex collection of molecules known as a ribosome is used by cells to assemble proteins. The ribosome puts amino acids in the correct order and connects them with peptide bonds. A polypeptide chain—a lengthy collection of amino acids—is produced by this procedure, known as translation.
Why do proteins matter in biology?Amino acids make up the chemical substances known as proteins. Up to four levels of structure can be found in proteins. Different proteins each have a complicated structure that gives them special characteristics. Proteins called enzymes speed up biological processes in cells. Proteins known as antibodies hunt down and kill infections.

Explanation:
White blood cells' main job is to fight of germs and diseases within the body. They have do not have a fixed shape which makes it easier for them to form a shape around the germs. Once they surround they can eat the germs or entangle them. Another adaptation is that they can produce antibodies that can also kill the germs.
Plants have specialized structures that help ensure reproduction. Which statement is an example of these structures?
A. An oak tree has thick bark.
B. A banana plant has green leaves.
C. Dandelion seeds blow in the wind.
D. Carrots grow underneath the soil.
The statement that best exemplifies specialized structures in plants is C: "Dandelion seeds blow in the wind."
This statement refers to the specialized structure of dandelion seeds, which have a feathery structure called a pappus that aids in dispersal through wind. Plants have evolved various specialized structures to ensure their reproduction and dispersal. In the case of dandelion seeds, their feathery pappus allows them to catch the wind and be carried away from the parent plant to new locations where they can germinate and grow.
This adaptation increases the chances of their survival and colonization in different areas. Specialized structures in plants can also include adaptations like bright flowers and sweet nectar to attract pollinators, thorns or spines for defense against herbivores, and underground storage organs like tubers or bulbs for nutrient storage and propagation.
These structures play crucial roles in the reproductive success and survival of plants in their respective environments, allowing them to disperse their offspring, attract pollinators, defend against threats, and establish themselves in diverse habitats. Therefore, Option C is correct.

Though the brain represents less than 2 percent of your body weight, it uses 25 percent of
the oxygen you breathe and 70 percent of your glucose supply.
The brain has five basic regions:
Cerebellum - Coordinates body movement.
Brain stem - Responsible for basic life functions such as blood pressure and breathing.
Thalamus - A Grand Central relay station for incoming data from all the senses except
smell.
Hypothalamus - A regulator of hunger, thirst, sleep, sexuality, and emotions.
Cerebrum - Our gray matter, home to thought, vision, language memory, emotions. It's
divided into hemispheres. If you're right-handed, odds are the right hemisphere is where
you make sense of music, images, space, emotions. Your left hemisphere is apt to focus
on math, language, speech. In left-handed people, tasks are usually reversed.
The brain works via the communication of nerve cells along complicated circuit patterns
that register on encephalograms as brain waves, including the relaxed "alpha waves" so
beloved by meditators.

In the United States about 16% of the population is Rh negative. The allele for Rh negative is recessive to the allele for Rh positive. If the student population of a high school in the U.S. is 3,000, how many students would you expect for each of the three possible genotypes?
In certain African countries, 4% of newborn babies have sickle-cell anemia, which is a recessive trait. Out of a random population of 10,000 newborn babies, how many would you expect for each of the three possible genotypes?
In the high school population of 3,000 students, 2,117 students were homozygous Rh positive (AA), 806 students were heterozygous (Aa), and 77 students were homozygous Rh negative (aa).
Given:
Population size: 3,000 students
Rh negative population frequency: 16% (0.16)
From the Hardy-Weinberg equation.
p: frequency of the dominant Rh positive allele
q: frequency of the recessive Rh negative allele
We know that p + q = 1
p = 1 - q = 1 - 0.16 = 0.84.
The expected frequencies of the three genotypes are:
Homozygous Rh positive (AA): p² = (0.84)² = 0.7056
Heterozygous (Aa): 2pq = 2 ₓ 0.84 ₓ 0.16 = 0.2688
Homozygous Rh negative (aa): q² = (0.16)² = 0.0256
Homozygous Rh-positive: 0.7056 ₓ 3,000 = 2,116.8 (approximately 2,117 students)
Heterozygous: 0.2688 ₓ 3,000 = 806.4
Homozygous Rh negative: 0.0256 ₓ 3,000 = 76.8

Why do those native to the Tibetan Plateau have an advantage (name the gene)? How does it provide an advantage? Use this excerpt to explain the relationship between adaptation and natural selection.
"Organisms, like a camel, have traits that allow them to survive in their environment. These traits are passed down through natural selection. Natural selection is the process where organisms better adapted to their environment will survive better and produce more offspring.. These traits are also known as adaptations. Adaptations can be anatomical (how the organism is built), behavioral, or physiological (how parts of an organism function). About 800 people each year attempt to climb Mount Everest. Mount Everest is located on the border between Tibet and Nepal in the Himalayas in Asia. The dangers of climbing Mount Everest include avalanches, cracking ice flows, and deep deadly crevices. However, the most trouble that climbers run into is altitude sickness. Altitude sickness is a group of symptoms that can happen when walking or climbing in higher altitudes. Most cases of altitude sickness are mild, while some symptoms can be life threatening. When climbing Mount Everest, there is an area known as the “death zone” that climbers hit when they reach about 8000 meters above sea level. In the death zone, the lungs and brain do not get enough oxygen, the risk of stroke and heart attack increases, and judgment is impaired. Those native to the Tibetan plateau have adapted to living at high altitudes with lower oxygen levels and are able to help mountain climbers. Tibetans have several genes that allow them to use less oxygen when they are working or exerting energy. Scientist have studied the genes of the Tibetans and found when one version of a gene was expressed, or allele, the people had a 10 percent higher saturation of oxygen. This means their blood contained 10 percent more oxygen than most people. The study also found that women who have the genotype for high oxygen saturation have more living children and lower death rates, which allows this gene to be passed from parent to offspring more efficiently. The gene that gives those native to the Tibetan plateau the advantage is the EPAS1 gene. This gene helps produce hemoglobin, an iron-containing red protein that carries oxygen in the blood.. The EPAS1 gene provides instructions for a protein that plays a role in the body’s ability to adapt to changing oxygen levels. The protein also controls cell division, forming new blood vessels and making new red blood cells. Scientists have compared the genetic makeup of the Tibetan people to those of Han Chinese people who live in the lowlands of Mount Everest. The two populations split, and Tibetans migrated to the highlands less than 3000 years ago. The scientists concluded that the EPAS1 gene was not prevalent in the Han Chinese population, and the increased abundance in the Tibetan people was a result of natural selection."
The Tibetan population found to have the EPAS1 gene is known to dwell in higher elevations, where the ability of red blood cells to deliver oxygen even in low oxygen settings is necessary by Natural selection.
Natural selection describes how organisms will live longer and reproduce more frequently if they are more adapted to their environment. Now, it's important to mention that individuals who carry the EPAS1 gene are able to withstand oxygen stress that may occur at high altitudes because of the elevation at which they live.
The Denisovans were a very ancient hominid (tribe) that lived throughout Asia throughout the lower and middle Paleolith.These species are now extinct. Their proof comes from physical remains and DNA found in fossils.They are believed to have lived in Siberia, Tibet, and Laos, based on fossil evidence.They made it to the Tibetan Plateau and adapted well to high altitude.They had black eyes, hair, and complexion, as well as a Neanderthal-like build and features, according to DNA data.The Denisovans, who went extinct shortly after mating with contemporary humans, are known to have interbred with them, and it has been discovered that the Tibetans received the high altitude gene from them.
Thus, it is discovered that members of the Tibetan community who reside at higher altitudes have the EPAS1 gene.

In photosynthesis, the inputs include 6 carbon (C) atoms, 12 hydrogen (H) atoms, and 18 oxygen (O) atoms. These atoms are obtained from carbon dioxide (\(CO_{2}\)) . Glucose \(C_{6} H_{12} O_{6}\), which contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Additionally, oxygen (O2) is released as a byproduct.In cellular respiration, the inputs are the same as the outputs of photosynthesis. This is because the products of photosynthesis, such as glucose and oxygen, serve as the inputs for cellular respiration. Glucose is broken down during cellular respiration to release energy. The process involves the consumption of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. The energy released is captured in the form of adenosine triphosphate (ATP), which is the energy-carrying molecule used by cells for various metabolic processes.For more such question on photosynthesis

4. The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell would be: which option is correct a) 1 mole of ATP b) 2 moles of ATP c) 3 moles of ATP d) 4 moles of ATP e) 6 moles of ATP
The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell is approximately 4 moles of ATP.
During oxidative phosphorylation, each mole of NADH can generate around 2.5 to 3 moles of ATP. Therefore, for 2 moles of NADH, the total ATP production would be in the range of 4 to 6 moles of ATP. While the more precise estimate falls within the 4 to 6 moles range, the closest option provided is 4 moles of ATP. It is important to note that the exact ATP yield can vary depending on factors such as the efficiency of the electron transport chain and the specific conditions within the cell.Since there are 2 moles of mitochondrial NADH, the total ATP yield would be around 4 to 6 moles of ATP. However, the most accurate option among the given choices is 4 moles of ATP.
