biologists who study biodiversity describe new species and monitor species of which we are aware. why is the study of biodiversity important in the anthropocene?
Answers
The study of biodiversity is important in the Anthropocene because it provides information about the species that go extinct every one thousand years.
Extinction happens when species are faded because of environmental forces consisting of habitat fragmentation, weather trade, natural disaster, over-exploitation by using people, and pollution, or because of evolutionary modifications in their members (genetic inbreeding, poor reproduction, decline in population numbers).
An extinction occasion is a giant and fast decrease in the biodiversity in the world. Such an occasion is recognized via a pointy change inside the diversity and abundance of multicellular organisms.
The main cutting-edge causes of extinction are the loss and degradation of habitat (Deforestation), over-exploitation, invasive species, climate exchange, and nitrogen pollutants.

what chemical interactions determine how a protein folds? select the three answers that are correct. interactions among side chains of amino acids interactions among side chains of nucleotides interactions among core structures of amino acids interactions between amino acids and nucleotides interactions between amino acid side chains and water
Answers
The chemical interactions determine protein fold Certain folding patterns are occasionally begun by hydrogen bonds between carboxyl groups and amino groups in adjacent protein chain regions.
The stable folding ways that make up the secondary form of a protein are referred to as alpha helices and beta sheets.
Hydrogen bonds, peptide bonds, and hydrophobic/hydrophilic interactions are the three kinds of chemical bonds that are found in proteins. A protein's secondary, tertiary, and quarternary structures all contain hydrogen bonds, which are referred to as interactions between H-O and H-N.
The hydrophilic R groups of nonpolar amino acids will lay on the outside of the protein while the hydrophobic R groups of amino acids will cluster together in the protein's interior during protein folding (in an aqueous compartment). These kinds of collaborations are known as hydrophobic cooperations.

How much more atp is generated from glucose 6-phosphate, compared to glucose, when it is metabolized by the glycolytic pathway?.
Answers
2 ATPs are generated from glucose 6-phosphate during the glycolytic pathway.
The glycolysis pathway, which is a series of enzyme-mediated steps, is used to metabolize G6-P in the cytoplasm of the cell. The first step of glycolysis is the isomerization of glucose-6-phosphate (G6P) into fructose-6-phosphate, which creates triose-phosphate and two pyruvate molecules as well as a small amount of ATP (net gain of 2 ATP molecules). The majority of ATP is then produced by the aerobic oxidation of pyruvate in differentiated cells. Although glucose is frequently regarded as the primary energy source for cells, it is actually primarily a major supply of carbon skeletons for cell growth and survival. Indeed, under some circumstances, particularly during prolonged fasting or during cell proliferation, glucose oxidation to CO₂ to provide energy should be avoided to allow the delivery of essential functions.

a. protein synthesis will stop.
b. nonessential amino acids will be converted into the missing amino acid.
c. glucose will be converted into the missing amino acid.
d. proteins will be made, but they will lack that particular amino acid.
Answers
The correct answer is d. Proteins will be made, but they will lack that particular amino acid. When an essential amino acid is missing from the diet, proteins can still be synthesized using the nonessential amino acids, but the resulting proteins will be incomplete and lack the missing essential amino acid.
Amino Acids
When an essential amino acid is missing from the diet, protein synthesis will stop (option a). Essential amino acids are those that cannot be synthesized by the body and must be obtained from the diet. Without all of the necessary amino acids, the body cannot build proteins and protein synthesis will be halted. Nonessential amino acids can be synthesized by the body and do not need to be obtained from the diet. Glucose is a carbohydrate and cannot be converted into amino acids. While proteins can be made without a particular amino acid, they will not be complete and will not function properly. Therefore, the correct answer is option a, protein synthesis will stop.

true or false? the goal of surgical closure of the palate is to establish an intact division between the oral and nasal cavities, including a fully functional velopharyngeal system.
Answers
The given statement "the primary goal of surgical closure of the palate is to establish an intact division between the oral and nasal cavities, as well as to create a fully functional velopharyngeal system" is True.
This is important to improve speech, swallowing, and overall quality of life for the patient.
The surgical procedure involves several steps.
First, the surgeon will carefully assess the patient's palate and the surrounding structures. This assessment helps to determine the appropriate surgical approach and techniques to achieve the desired outcome.
Next, the surgeon will make incisions on both sides of the cleft palate, which will allow the tissues to be repositioned and reconnected. This process is called tissue mobilization and is essential to create an intact separation between the oral and nasal cavities.
Once the tissues have been mobilized, the surgeon will carefully suture the muscles and other soft tissues in the palate to create a functional velopharyngeal system.
The velopharyngeal system plays a critical role in speech and swallowing, as it controls the opening and closing of the connection between the oral and nasal cavities during these functions.

Investigation 1.6: Kissing the Right Way
Most people are right-handed and even the right eye is dominant for most people. Researchers have long believed that late-stage human embryos tend to turn their heads to the right. German biopsychologist Onur Güntürkün (Nature, 2003) conjectured that this tendency to turn to the right manifests itself in other ways as well, so he studied kissing couples to see whether both people tended to lean to their right more often than to their left (and if so, how strong the tendency is). He and his researchers observed couples from age 13 to 70 in public places such as airports, train stations, beaches, and parks in the United States, Germany, and Turkey. The observers were careful not to include couples who were holding objects such as luggage that might have affected which direction they turned. We will assume these observations are representative of the overall decision-making process when kissing.
Practice Problem 1.8A
In Investigation 1.6, Dr. Güntürkün conjectured that 2/3 of kissing couples lean right.
(a) Would the normal approximation (Central Limit Theorem) be valid for the kissing study in Investigation 1.6? Justify your answer.
Answers
"The investigation 1.6 study on kissing couples was conducted by German biopsychologist Onur Güntürkün to determine whether couples have a tendency to lean towards their right when kissing.A central limit theorem approximates a sampling distribution to a standard normal distribution if a few requirements are satisfied. The central limit theorem is valid only for the large sample size, i.e., n > 30. The theorem may be applicable even for n < 30 if the sample distribution is approximately symmetrical. So, the normal approximation (Central Limit Theorem) would be valid for the kissing study in Investigation 1.6 since it was carried out on a large number of people from the United States, Germany, and Turkey aged between 13 and 70 in public places such as airports, train stations, beaches, and parks. Hence, the normal approximation would be valid for this study.

why must dsrna viruses package an rna-dependent rna polymerase (rdrp) inside their viral capsid?
Answers
dsRNA viruses package an RNA-dependent RNA polymerase (RdRp) inside their viral capsid because this enzyme is essential for viral replication. Unlike cellular RNA polymerases, which require a DNA template to synthesize RNA, RdRp can use viral RNA as a template for RNA synthesis.
1. Genome replication: RdRp is essential for replicating the virus's dsRNA genome. Upon entering a host cell, the RdRp synthesizes new RNA strands, ensuring the viral genetic material can be propagated.
2. Host cell machinery: Unlike single-stranded RNA viruses, dsRNA viruses cannot utilize the host cell's machinery for replication. Packaging RdRp within the capsid ensures the necessary enzyme is available for replication within the host cell.
3. Transcription: RdRp plays a vital role in the transcription process of dsRNA viruses, creating mRNA from the viral dsRNA genome. This mRNA is then translated into viral proteins by the host cell machinery.
4. Compartmentalization: Packaging RdRp within the viral capsid helps protect the enzyme from degradation by host cell defenses, ensuring its availability for viral replication and transcription.
In summary, dsRNA viruses package RdRp inside their viral capsid to facilitate genome replication, utilize host cell machinery for transcription, and safeguard the enzyme from degradation, ensuring a successful infection.
