In a certain reptile, eyes can be either black or yellow. Two black eyed lizards are crossed, and the result is 72 black eyed lizards, and 28 yellow-eyed lizards. Calculate the chi-squared value for the null hypothesis that the black eyed parents were heterozygous for eye color. Explain the chi-square test results.
Answers
Assuming a single diallelic gene coding for the eye color trait, the chi-square test results suggests that there is not enough evidence to reject the null hypothesis. Parents must be heter0zyg0us. 0.48 < 3.841
Available dataEyes are black or yellowCross: between two black eyed lizardsF1) 72 black eyed lizards, and 28 yellow-eyed lizards.Assuming the eye color is coded by a single diallelic gene and that black is dominant over yellow, we will name the alleles B for black and b for yellow.
Hypothesis: Two heter0zyg0us lizards are crossed. Bb x Bb
The expected phenotypic ratio among the progeny is 3:1,
3/4 expressing the dominant trait, and 1/4 expressing the recessive trait.So, according to these proportions, we can get the expected numbers
4 ------------------- 100 individuals
3 ------------------- X = 75 black-eyed individuals
1 -------------------X = 25 yellow-eyed individuals
Now, we will compare the observed values and the expected values.
Black eyes Yellow eyes
Observed 72 28
Expected 75 25
(Obs-Exp)²/Exp 0.12 0.36
X² = Σ(Obs-Exp)²/Exp = 0.12 + 0.36 = 0.48
So the chi-square value is 0.48.
Now we will compare this value with the critical table value. To do it, we need to know the degrees of freedom and the significance level.
Degrees of freedom = n - 1 = 2 - 1 = 1
Significance level = 0.05
Critical value = 3.841
X² < Critical value
0.48 < 3.841

Errors in transcription occur about 100,000 times as often as do errors in DNA replication. B) Why do you think a cell can tolerate a higher rate of error in RNA synthesis than in DNA synthesis?
Answers
Cells tolerate higher rates of error in RNA synthesis because many copies of that RNA will be made, and only some of them have errors, which means that a high number of normal copies are also made, being enough to overcome and correct the problem. Another point is that DNA molecules are temporarily inherited. When it comes to errors in DNA synthesis, the mutation can be permanent if it`s not corrected until the next cell division, which makes errors in DNA synthesis more dangerous and with more consequences than in RNA synthesis, leading the cell to tolarate only a lower rate of errors.
if the original source of organic material is then mostly natural gas will be formed, as opposed to mostly forming oil. group of answer choices higher order animals, e.g., dinosaurs higher plants, e.g., trees, shrubs, and grasses plankton, e.g., algae, copepods, and bacteria
Answers
The original source of organic material like oil is most likely to form because tiny algae and plankton decomposed under conditions of heat, pressure, and low oxygen.
Algae are a kind of mostly aquatic, photosynthetic, nucleus-bearing creatures that are not real roots, stalks, leaves, or other multicellular reproductive structures like those seen in plants. Photosynthesis is a trait of algae.
The majority of plankton species are minuscule and frequently less than an inch long, but they also include some bigger species like certain crabs and jellyfish.
What are the earliest forms of life?
Dinosaurs existed 250 to 201 million years ago, plants and trees 500 million years ago, and people only 2 million years ago.
Microbes, the oldest known living forms, left traces of their existence in rocks that were 3.7 billion years old. A particular class of carbon molecules created by living beings made up the signals.
Therefore, the original source of organic material like oil is most likely to form because tiny algae and plankton decomposed under conditions of heat, pressure, and low oxygen.

In the presence of oxygen, oxidative phosphorylation is the first stage of cellular respiration.
What is cellular respiration?Cellular respiration may be characterized as a type of chemical process through which oxygen is utilized in order to derive energy from carbohydrates (sugars). This chemical process involves the breakdown of food in the cell with the release of energy.
The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation. Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue and perform oxidative phosphorylation.

92ml 3.0 fl oz what is the ratio
Answers
The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).
1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).
Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).
Now we can express the ratio between 92 mL and 88.72 mL:
92 mL : 88.72 mL
Simplifying the ratio by dividing both sides by the greatest common divisor, we get:
46 : 44
So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

In dividing cells, most of the cell's growth occurs during “_____”
Answers
Answer:
In dividing cells, most of the cell's growth occurs during interphase. 5. The mitotic spindle(s) is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division.
During interphase, DNA replication and cell expansion take place. During the mitotic phase, the cell divides and the DNA replication and cytoplasm are segregated.
What is the role of interphase in cell growth?The majority of a cell's time is spent in the phase known as interphase, during which it matures, copies its chromosomes, and prepares to divide. The cell then completes mitosis, leaves interphase, and divides to completion.
During the mitotic (M) phase, the cell splits into two new cells by dividing its cytoplasm and DNA into two sets.
Chromosomes will line up, split, and move into new daughter cells during mitosis. Interphase occurs between one mitotic (M) phase and the next because the prefix inter- signifies between.
