What are four conditionsrequired for fossilizationof an organism?
Answers
Answer:
The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition. This does make the fossil record biased because animals with soft bodies are less likely to form fossils.

Using your understanding of diffusion, how do you think oxygen from our lungs is transported to our red blood cells?
Answers
Red blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs into the RBCs, where it binds to hemoglobin. One molecule of hemoglobin can bind four molecules of oxygen (O2).

Explain how Chromosomes are like a ball of yarn (use the words chromosome, DNA, and gene in your answer)
Answers
Answer:
Chromosomes are like a ball of yarn in the sense that there are multiple components that make up the structure. Genes can be in similitude of the smallest threads in the yarn and when a multitude of genes are put together they make a DNA strand or a long, thick thread of yarn. Lastly, when DNA is twisted together, it becomes bundled together, making a chromosome or a "ball of yarn".

In humans, brown eyes are generally dominant over blue eyes. Find the phenotypic and genotypic ratios of a cross between two heterozygous brown-eyed people. Choose This is a required question
Answers
Answer:
Brown eyed genotype: Aa (eterofzygous) or AA (homofzygous)
The genotypes derived from the cross are: AA, Aa, Aa, aa
The phenotypes are: 3 with brown eyes and 1 with blue eyes (aa)
The phenotypic ratio is 3:1 (brown eyes: blue eyes) and the genotypic ratio is 1:2:1 (dominant homozygous: heterozygous: recessive homozygous).
What happens in a heterozygous cross?In humans, the allele for brown eyes (B) is dominant over the allele for blue eyes (b). Heterozygous individuals, who carry one copy of each allele (Bb), will have brown eyes.
When two heterozygous brown-eyed individuals (Bb) cross, the possible genotypes of their offspring are:
BB (brown eyes): 25% chance (homozygous dominant)
Bb (brown eyes): 50% chance (heterozygous)
bb (blue eyes): 25% chance (homozygous recessive)
So, the genotypic ratio of the offspring is 1:2:1 (BB:Bb:bb).
As for the phenotype, the only possible one is brown eyes and it occurs in 75% of the offspring (25% BB + 50% Bb)
Therefore, the phenotypic ratio of the offspring is 3:1 (brown eyes: blue eyes)
It's worth noting that while this is the typical outcome of crosses involving the eye color genes, it's not universally accurate, as other factors and genes might have an influence on the phenotype. Additionally, in reality, eye color is a complex trait and many other genes are involved not just B and b, so the dominance is not always that clear.

What enzyme in organisms is Taq Polymerase similar to? Why?
Answers
Taq polymerase is a common enzyme used for PCR amplification. It is similar to E. coli DNA dependant DNA polymerase I. It is so because of the strong homology at the amino acid level. The 3′-OH nucleotide addition site, the dNTP/DNA binding sites, and the 5′-3′ exonuclease sites of both the enzymes.
What is E. coli DNA dependant DNA polymerase I?The DNA polymerase I is mainly used for repair of the damaged DNA. It also helps to connect Okazaki fragments by deleting RNA primers.
E. coli DNA dependant DNA polymerase I has similar properties like Taq polymerase as they both have strong homology at the amino acid level.
The 3′-OH nucleotide addition site, the dNTP/DNA binding sites, and the 5′-3′ exonuclease sites of both the enzymes.
Thus, it can be concluded that E. coli DNA dependant DNA polymerase I is the enzyme similar to Taq polymerase.

What climate changing causes are not in human control
Answers
Explanation:
The climate is changing — the thing is, it isn’t just due to humans.
Natural forces beyond human control are also gradually affecting our climate. These geophysical forces are vital to understanding global warming. Man is indeed responsible for a large portion — possibly even a majority — of global warming. But also in play are complex gravitational interactions, including changes in the Earth’s orbit, axial tilt and torque.
This fact needs to be included in the public debate. Because these gravitational shifts, occurring over millennia, can influence climate patterns and ultimately lead to noticeable variations in seasons. Interestingly, research suggests climate change can alter the tilt of the Earth, but an unrelated change in tilt can also further change the climate. It is a balance-counterbalance relationship.
Changes in the Earth’s path around the Sun, or eccentricity, involve shifts in the orbit around the Sun from a roughly circular journey to more of an elliptical one. When the Earth gradually adopts a more elliptical orbit, there are more pronounced temperatures during the summer and winter months. This alteration is exacerbated when the Earth’s axial tilt is inclined to a sharper degree than usual. As this happens, it causes the North and South Poles to be positioned more directly toward the Sun.
Haven’t you noticed the recent rise in irregular weather patterns? This is not just a man-made problem. Gradual slight variations in the Earth’s orbit around the Sun can strongly influence temperature extremes. This is important because the conversation around climate change has become so politicized, we've totally lost sight of the science — and with it, any room for bipartisanship.
