Can humans turn into fossils why or why not?
Answer:
Certain types of animals are more likely to end up as fossils. ... On the other hand, it turns out humans are actually fairly well-suited to becoming fossils. “Mammals have a very good record, because teeth make fantastic fossils,” says Norell. “They're incredibly hard, incredibly resilient.
Explanation:
Answer:
well probably we humans are almost, practically fit for fossils so we have a chance to turn into a fossil

Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because:
A. Phosphorolysis reactions cleave bonds with phosphate instead of water.
B. Phosphorylase is a better enzyme than hexokinase
C. Phosphorylase produces a glucose phosphate without spending an ATP to do it
D. All of these
Answer:
A
Explanation:
The answer is a Because Phosphorolysis reactions cleave bonds with phosphate instead of water (: just trust me
Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because phosphorolysis reactions cleave bonds with phosphate instead of water. The correct option is A.
What is glycolysis?Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons.
The metabolic process that changes glucose into pyruvate is known as glycolysis.
The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process. A series of ten enzyme-catalyzed processes make up glycolysis.
In contrast to phosphorolysis reactions, which cleave bonds with phosphate rather than water, glycolysis can be thought of as having a larger energy yield because it begins with glycogen rather than glucose.
Not producing adenosine 5′-triphosphate is not the primary goal of glycolysis; rather, it is to produce pyruvate for the trichloroacetic acid (TCA) cycle.
By boosting the ratio of NADH to NAD+, the glycolytic synthesis of pyruvate lowers the cytosol.
Thus, the correct option is A.

How do changes to genes affect the traits of an organism
Changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.
What is the significance of the genes or the traits?Changes in the genes can affect humans in several ways, such as through genetic mutations that result in changes to the regulation of gene expression and result in the addition or loss of entire genes from the organism. Not all of the genetic mutations lead to expressiable changes, but they may change the protein sequence by changing the polypeptide sequence.
Hence, changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.

For this structural characteristic, decide if it is a characteristic of DNA, a characteristic of RNA, a characteristic of both or a characteristic of neither? It contains thymine as a base
Answer:it is a characteristic of DNA
Explanation:
Deoxyribonucleic acid(DNA) is made 5 carbon deoxyribose sugar, phosphate group,Nitrogenous base which include purine and pyrimidine. Purine base compose of Adenine and guanine while pyrimidine base compose of Cytosine and thymine.
In Ribonucleic acid (RNA) we have 5 carbon ribose sugar, phosphate group and nitrogenous bases which are purine and pyrimidine. Purine consist of Adenine and guanine while pyrimidine compose of Cytosine and Uracil where thymine in DNA is replaced by Uracil in RNA. This makes Thymine a components of DNA not RNA.
Look at the speedometer at the top. What do you notice about the speed when the skater goes from a height of 6m down to 0m and back up to 6m?
Answer:
First increases then decreases.
Explanation:
The speed of skater tends to increases when it moves from high elevation of 6 m to the low height area due to sloppy region while on the other hand, when the skater moves again from 0 m or from the ground level to 6 m height its speed decreases when reaches to the highest point. First the speed of the skater increases due to moving in the direction of gravity while on other hand, the speed of the skater decreases due to movement of skater against the gravity of earth.
Compare marshes, swamps, and bogs.
Answer:
Marshes: Have extremely good ability to support grasses, reeds, flowers, and insects due to their high nutrient soil. They usually are around lakes/rivers/and other bodies of water. They are frequently covered in water however not always covered in water.
Swamps: Have extremely good ability to support wood like plants, trees. They are also permanently covered/submerged in water all year around.
Bogs: Basically they are a gravesite of a dead plant life. When a lake fails to support itself it turns into a bog, its plant life dies off and will start rising to the top creating almost a film. However even though the plant life dies the insects, reptiles, and Amphibians thrive.

You are studying a biochemical pathway in the mold Neurospora where enzyme 1 converts the initial substrate into intermediate substrate A; enzyme 2 converts intermediate substrate A into intermediate substrate B; enzyme 3 converts intermediate substrate B into intermediate substrate C; and enzyme 4 converts intermediate substrate C into the end product, an amino acid that is essential for growth. You isolate a mutant that is unable to grow on minimal media. Which data would provide the strongest support for the hypothesis that this mutation occurred in the gene that codes for enzyme 2
Complete question:
You are studying a biochemical pathway in the mold Neurospora where enzyme 1 converts the initial substrate into intermediate substrate A; enzyme 2 converts intermediate substrate A into intermediate substrate B; enzyme 3 converts intermediate substrate B into intermediate substrate C; and enzyme 4 converts intermediate substrate C into the end product, an amino acid that is essential for growth. You isolate a mutant that is unable to grow on minimal media. Which data would provide the strongest support for the hypothesis that this mutation occurred in the gene that codes for enzyme 2?
a. The mold can grow on rich medium plus intermediate substrate C, but not on rich medium plus intermediate substrate B.
b. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus the initial substrate.
c. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus intermediate substrate A.
d. The mold can grow on rich medium plus intermediate substrate D, but not on rich medium plus intermediate substrate C.
e. The mold can grow on minimal medium plus intermediate substrate A, but not on minimal medium plus intermediate substrate C.
Answer:
c. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus intermediate substrate A.
Explanation:
Let us first diagram the pathway for a better understanding.
The normal organism produces four enzymes that convert substrates in the medium that allow it to survive, grow, and reproduce.
initial substrate ------------> A ----------------> B ----------------> C ----------------> AA
Enzyme 1 Enzyme 2 Enzyme 3 Enzyme 4
Any mutation on the Neurospora´s enzymes will not let the organism grow on the minimal medium because it will not be able to convert the minimal substrate into the following one, because the mutated enzyme will not accomplish its original function.
So if the mutation occurs in enzyme 1, the organism will not be able to convert the initial substrate into intermediate substrate A. And the rest of the reaction will not be possible either because of the lack of substance A.initial substrate -----X----> A -------X-----> B ------X--------> C ------X-------> AA
mutated Enzyme 1 Enzyme 2 Enzyme 3 Enzyme 4
If the mutation occurs in enzyme 2, the organism will not be able to convert the intermediate substrate A into intermediate substrate B. And the rest of the reaction will not be possible either because of the lack of substance B.
initial substrate ------------> A -------X--------> B -------X------> C --------X-----> AA
Enzyme 1 mutated Enz. 2 Enzyme 3 Enzyme 4
If the mutation occurs in enzyme 3, the organism will not be able to convert the intermediate substrate B into intermediate substrate C. And the last reaction will not be possible either because of the lack of substance C.
initial substrate ------------> A ----------------> B -------X--------> C -------X------> AA
Enzyme 1 Enzyme 2 mutated Enz. 3 Enzyme 4
And if the mutation occurs in enzyme 4, the organism will not be able to convert the intermediate substrate C into the essential amino acid.
initial substrate ------------> A ----------------> B ----------------> C -------X-------> AA
Enzyme 1 Enzyme 2 Enzyme 3 Mutated Enz. 4
But, if we artificially add to the medium the substrate that should be produced by the original enzyme (and that is not converted because of the mutation), then the organism will grow and survive because the other enzymes will be able to produce the essential amino acid.
So, if enzyme 2 is the only enzyme mutated, the organism will not be able to live in a medium with substrate A because the mutated enzyme will not convert the substrate A into B. There will not be B substrate in the medium, and the other enzymes will not produce the essential amino acid. So if the mutation occurs in enzyme 2, substrate A is useless to the organism because it will not survive.
But if we add the intermediate substrate B to the medium, the organism will survive. In a medium with substrate B, all the other reactions will be possible, and the organism will get the essential amino acid. The artificial addition of B substrate will replace the function of the original enzyme 2 -which is the one that converts A into B-.

In a eukaryotic cell, which of the following processes directly involves DNA?
The provided question lacks the options, however, the options associated with the question is as follows;
A. translation
B. cellular respiration
C. active transport of ions
D. replication of chromosomes
Answer:
The correct answer is - D. replication of chromosomes.
Explanation:
During every cell division, either meiosis or mitotic the chromosomal DNA present in the nucleus is needed to be duplicated and the process that involves the duplication of this chromosomal DNA is known as replication of chromosome which takes place during the interphase of the cell division.
All other processes mentioned in the options are not involved or directly not involved in the processes. Translation involves the mRNA in the cytoplasm to produce amino acids with the help of ribosomes. Cellular respiration involves mitochondria and does not require DNA in the process.

In corgis, a breed of dog, short tails are completely dominant to long tails. If two long-tailed corgis have puppies, what is the percent chance of having a puppy with a short tail?
Answer:
0%
Explanation:
This question involves a single gene coding for tail length in a breed of dog called Corgis. The allele for short tail (S) is dominant over the allele for long tail (s).
According to this question, two long-tailed corgis are crossed i.e. ss × ss. Each parent corgis will produce only 's' gametes. Using this gametes in a punnet square (see attached image), the following proportion of puppies will be produced:
All ss (long-tailed) offsprings/puppies.
Based on the question asked, 0% or none of the puppies produced will have a short tail.
Apply Concepts Eventually, most people with Alzheimer's disease lose the ability to recognize common objects. Explain which lobe is affected at this point in the disease
Answer:
The right temporal lobe
Explanation:
The cerebral cortex of the brain has two sections known as hemispheres, and each hemisphere can be divided into four lobes: frontal, parietal, temporal and occipital. Alzheimer's disease is the most common cause of dementia, which is characterized by the damage of the temporal lobe. Alzheimer’s disease usually initiates in the hippocampus, which is a structure inside each temporal lobe. The temporal lobes are involved in different neuronal functions: object recognition, face recognition, perception, memory, language, emotions, etc. The right temporal lobe is mainly involved in processing visual information (i.e., face recognition, object recognition, familiar recognition).
Some evidence on the safety of vaccines.
Answer:
The safety and effectiveness of vaccines are under constant study. Because vaccines are designed to be given routinely during well-child care visits, they must be extraordinarily safe. Safety testing begins as soon as a new vaccine is contemplated, continues until it is licensed, and is monitored indefinitely after licensure.
Explanation:
Answer:
well
Explanation:
Before a vaccine is ever recommended for use, it’s tested in labs. This process can take several years. FDA uses the information from these tests to decide whether to test the vaccine with people.
During a clinical trial, a vaccine is tested on people who volunteer to get vaccinated. Clinical trials usually start with 20 to 100 volunteers, but eventually include thousands of volunteers. These tests can take several years and answer important questions like:
