Cytochrome C is a protein that functions in cellular respiration as part of the electron transport chain. It is frequently used to determine evolutionary relationships between different organisms because it is highly conserved (only differs slightly) between different organisms. A student researching evolutionary relationships between different organisms came across the following information about the differences between cytochrome C proteins in different organisms when compared to humans. Number of different amino acids compared to humansChimpanzee0Rhesus Monkey1Cow10Yeast42 The student plans to use an antibody to the human cytochrome C protein in an ELISA test on cytochrome C samples from these four organisms. What should she use as a positive control
Answer:
Human cytochrome C
Explanation:
The enzyme-linked immunosorbent assay (ELISA) is a technique widely used to detect and measure antibodies and antigens in biological samples. This technique can be used to diagnose different diseases by detecting antigens that bind to antibodies. The ELISA test consists of a plate with a capture antibody against the antigen of interest coating the plate. Subsequently, the target antigen is detected by adding a detection antibody labeled with an enzyme (e.g., alkaline phosphatase) that binds to this antigen. Finally, a particular substrate (e.g. ABTS) is added to the plate and the subsequent reaction converts it into a colored product which can be easily detected using microplate readers. In this case, the positive control will be human cytochrome C which will bind to specific antigens in order to evidence the presence of this molecule in the sample.

In 2-3 sentences, explain how crossing over and independent assortment in sex cells affect the appearance of the fully developed organism.
Answer:
Explanation:
Crossing over and independent assortment in gametes (sex cells) can lead to genetic variation in the DNA of these gametes and lead to offspring looking different from their parents. Crossing over is the exchange of DNA between a pair of homologous chromsomes (the mom and the dad) which results in recombinant chromsomes that have new combinations of genes. Independent assortment refers to the lining up of chromsoomes along the metaphase plate in meiosis 1, and this can lead to different combinations of gametes.

A garden contains 40 flowers, 30 of which are red. What is the frequency of red flowers?
Answer:
0.75
Explanation:
a frequency of 1.0 occurs when all the flowers are red
A garden that contains 40 flowers, 30 of which are red. Then, the frequency of red flowers is 75% of 1:3.
What is Frequency?Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as the temporal frequency for clarity, and is distinct from angular frequency. Frequency is usually measured in hertz (Hz) which is equal to one event per second.
Gene frequency is the fraction or percentage of a population which carries a particular allele at a particular gene locus. In this case, a garden has 40 flowers, in which 30 are red.
Therefore, the frequency of red flowers = Number of red flowers/ Total number of flowers
The frequency of red flowers = 30/ 40 = 75% or 1/3

Most cells in our body have two versions of each chromosome (Body cells). These cells are called diploid. We grow and replace these cells with identical cells through a cell division called mitosis.
For sexual reproduction, we need to make cells that have only one version of each chromosome (sex cells). These cells are called haploid. These unique cells are made through a cell division called meiosis.
Explanation:
haploid = 1
diploid= 2 // "di"=2
our body contains 46 chromosomes, half from our dad and a half from our mom. our repoductive contains 23 chromosomes.

⭐Is there an advantage for the different anole species being able to occupy different parts of a habitat?
Yes, since the Anolis sagrei inhabits humid lowland forests and dry lowland forests. Apparently it prefers areas that have very low or little ground cover (18, 23).The green anole lizard, Anolis carolinensis, has adapted to living in the tree canopy and can lead to speciation, Different species of anoles have different dewlaps, and very different vegetation.

Why are Wind Turbines being moved offshore?
Answer:
Wind turbines are being moved offshore because the wind comes at the right time: Offshore winds are usually higher throughout the day, allowing for more reliable and productive electricity output when market demand is highest. The majority of land-based wind resources are more efficient at night when demand for electricity is smaller.
For each glucose that enters glycolysis, _____ acetyl CoA enter the citric acid cycle. For each glucose that enters glycolysis, _____ acetyl CoA enter the citric acid cycle. 4 1 5 0 2
Answer:
For each glucose that enters glycolysis, 2 acetyl CoA enter the citric acid cycle.
Explanation:
SYNTHESIS OF 2Acetyl CoA -:
The glucose is transformed into 2pyruvate (6 carbon molecules are converted into 2 -3 carbon molecules) during glycolysis. In both aerobic and anaerobic respiration, glycolysis occurs frequently. This process takes place in the cytoplasm (it does not require oxygen or mitochondria), but if both oxygen and mitochondria are present, two molecules of pyruvate join mitochondria and prepare for citric acid cycle.
Until entering this, the molecules go through a mechanism known as the linked (connects glycolysis with citric acid cycle) reaction, in which the pyruvate molecule is transformed into 2 acetyl CoA (meaning 3 carbon molecules are converted into 2 carbon molecules) and a carbon molecule is released in the form of [tex]2CO_2[/tex] (waste product).
2NAD+ and NADH are synthesized in the linked reaction, implying that reducing power is produced. It means that electrons from pyruvate are released in the form of hydrogen, which 2NAD+ accepts and reduces to form 2 NADH.
[tex]Glucose[/tex] → [tex]2pyruvate[/tex] → [tex]2Acetyl CoA[/tex]
Linked reaction is also known as oxidative -dicarboxylation.
Hence, 2 Acetyl CoA is required to enter citric acid cycle.
