Suppose researchers marked 200 turtles and later were able to trap a total of 30 individuals in that population, of which 15 were marked. What is the estimate for total population size
The researchers estimate that the total population size of turtles in the area is approximately 400 individuals.
The researchers used a marking and recapture method to estimate the total population size of turtles. By marking 200 turtles and then recapturing 15 of those marked turtles out of a total of 30 captured,
The researchers can estimate the population size using a formula. The formula is as follows: N = (M x C) / R, where N is the estimated population size, M is the number of turtles marked in the first sample,
C is the number of turtles captured in the second sample, and R is the number of marked turtles captured in the second sample.
Using the values provided, we can calculate the estimated population size as follows: N = (200 x 30) / 15 = 400, Therefore, the researchers estimate that the total population size of turtles in the area is approximately 400 individuals.
It's important to note that this is just an estimate and there could be some variability in the actual population size. However, this method is widely used by researchers to estimate population sizes and is a useful tool in conservation efforts.

In your own words, explain how a single molecule of glucose is converted into ~30 or more molecules of ATP in cellular respiration
Answer: Throughout the stages of cellular respiration
Explanation:
Fair warning I'm only a college freshman so you may be able to find more detailed answers than what I'm about to give you.
During cellular respiration there are a number of processes that must be taken into account when dealing with a glucose molecule.
Glycolysis: The molecule of glucose is a 6-carbon molecule, in this process that takes place in the cytoplasm of the cell, it is split into two 3-carbon molecules, these are pyruvates, during this, 2 ATP is made as a byproduct(along with 2 NADH molecules but I'll just focus on the ATP moving forward).
Transformation of pyruvate: For eukaryotic cells, the pyruvate molecules from Glycolysis are transferred into the mitochondria, which of course are sites for cellular respiration. With Oxygen available, aerobic respiration would continue but if not, fermentation would take place which would drastically reduce total ATP reduction throughout one cycle. The pyruvates are transformed into a 2-carbon acetyl group which is then oxidized and now compatible for Coenzyme A to pick up, which results in the compound Acetyl Coenzyme A. This process ends up producing 1 NADH molecule from the reduction of NAD+ due to the 2 carbon molecule being oxidized.
Citric Acid Cycle: This stage begins as soon as Acetyl CoA combines with a 4-carbon molecule called Oxaloacetate which ends up forming citric acid, that has 6-carbon atoms. Long story short the citric acid goes through a great number of reactions that produces a total of 2 ATP molecules.
Oxidative Phosphorylation: This stage of aerobic respiration consists of the electron transport chain and chemiosmosis process. The energy of NADH and FADH2 molecules that were produced in the Citric Acid Cycle is what's used to create the final majority of ATP molecules within this whole process. 1. Throughout the electron transport chain, excited electrons move along its network in the inner membrane of the mitochondria. As it moves, molecules it passes by uses the electrons energy to pump Hydrogen ions/protons from the inner membrane towards the intermembrane space. This transfer of ions creates an electrochemical gradient which is necessary for the synthesis of ATP in the following process, Chemiosmosis. The Electron Transport Chain produces about 2-3 ATP. 2. In Chemiosmosis, the newly formed electrochemical gradient causes the gathered Hydrogen ions to flow from the intermembrane space into the matrix, therefore lowering the its concentration(search up a image of this if you need to). This flow is thanks to and mediated by ATP synthase. Finally ATP synthase accepts 3-4 Hydrogen ions so an inorganic phosphate group can react with an ADP (Adenosine diphosphate) compound to produce one ATP molecule. In total, 24-28 molecules of ATP is formed.
This is how a single molecule of glucose can produce more than 30 molecules of ATP in aerobic cellular respiration. Fermentation on the other hand, would most likely produce half of which aerobic respiration would produce.

You believe a bacterium is attaching to animal cells by binding to the carbohydrate portion of a specific glycoprotein. To test this hypothesis you pre-incubate the bacteria with various molecules and then test for inhibition of attachment to the animal cells. Which result supports the hypothesis that the bacteria recognize the carbohydrate component of the animal glycoprotein?.
You believe a bacterium is attaching to animal cells by binding to the carbohydrate portion of a specific glycoprotein. To test this hypothesis you pre-incubate the bacteria with various molecules and then test for inhibition of attachment to the animal cells. Pretreatment with the protein component alone prevents bacteria attachment to the animal cells supports the hypothesis that the bacteria recognize the carbohydrate component of the animal glycoprotein.
Animal glycoproteins are composed of two separate components: proteins and carbohydrates. We wish to demonstrate that the supplied bacteria binds to the glycoprotein's carbohydrate part rather than its protein portion.
We can treat the bacteria with just the protein portion of the glycoprotein if we wish to demonstrate that the bacteria only binds to the carbohydrate element of the glycoprotein.
It is easily demonstrated that the bacteria does not connect with the animal glycoprotein through the protein part if the bacteria is unable to bind to the protein component. It basically means that bacteria will only interact with glycoproteins through their carbohydrate parts.

large crystals are made from the slow cooling of magma
Large crystals are made from the slow cooling of magma because slow cooling allows for the formation of larger crystal structures.
How are large crystals formed? Large crystals can be formed through the process of cooling magma. Magma is molten rock that is located below the earth's surface. As magma cools, minerals can begin to crystallize and form solid structures.
The speed at which the magma cools plays a significant role in the formation of crystals. The slower the cooling process, the larger the crystals will grow. This is because slow cooling allows for the formation of larger crystal structures.
A common example of large crystal formation is granite. Granite is a rock composed of several minerals, including quartz, feldspar, and mica. When magma cools slowly, these minerals can crystallize and form large, visible crystals of up to several centimeters in length.
Larger crystals can also form through other geological processes such as metamorphism, where existing rocks are altered due to heat and pressure, or from the precipitation of minerals from water.

if you try to predict a sequence of daphnia protein by applying the genetic code to its genomic dna, do you think that would be accurate?
If we apply the "genetic-code" to the genomic DNA of Daphnia, we can predict the sequence of its protein-coding genes, but the accuracy of this prediction would depend on quality of the genome assembly and annotation.
The Genome assembly and annotation can be challenging, especially for organisms with complex genomes, repetitive sequences, or high levels of genetic variation. Errors in the genome assembly, such as mis-assemblies , can result in incorrect gene predictions.
The gene prediction algorithms can make errors, such as predicting a non-coding sequence as a protein-coding gene, or failing to predict a gene that is present.
