In 1973, biologist Theodosius Dobzhansky wrote an essay titled "Nothing in Biology Makes Sense Except in the Light of
Evolution." Why is evolution so important for understanding biology? Explain your answer in 1-2 sentences. (2 points)
Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.
What is the purpose of the theory of evolution?The Theory of Evolution states that it is the environment, through natural selection, that determines the importance of the individual's characteristic or its variations, and the organisms best adapted to this environment have a greater chance of survival, leaving a greater number of descendants.
With this information, we can conclude that Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.

A scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans.
After doing DNA analysis, they determine that the organisms share the following percentages of DNA:
Organism A and humans share 85% of their DNA.
Organism B and humans share 80% of their DNA.
Organism C and humans share 90% of their DNA,
Based on this information, which order should they go on the cladogram (from least related to most related)?
(1 point)
O A, B, C, humans
OB, A, C, humans
o C, B, A, humans
OC, A, B, humans
B, A, C, Humans is the correct answer
Heyo! ;D
So, just to give you a heads up, these do change and sometimes vary for some, however please make sure before you look into these. Thanks! Just pre-warning!
1. The two organisms that are the most closely related would be:
~A and C~2. Based on the information of percentages of DNA, the order they should go on the cladogram (from least related to most related) would be:
~B, A, C, humans~3. The evidence that would support the relationships shown on the graph between amphibians, reptiles, birds, and mammals would be:
~Mammals have more genes in common with birds than with amphibians.~4. The piece of evidence, if true, that would most likely weaken the hypothesis that humans and chimpanzees have a common ancestor to gorillas would be:
~The cells of the eye on embryos of gorillas and humans follow a similar pattern of development while chimpanzee embryos are different.~5. The similarity of the structures of the forelimbs of bats and humans are known as:
~homologies~because they result from species evolving:
~from the same common ancestor~6. The suggestion above discussing the fact "all vertebrate embryos have a tail and gill slits at some point during embryonic development" helps to suggest that:
~These species share a common ancestor.~7. The conclusion that can be made based on the statement "Fossil A is found closer to the surface compared to Fossil B." would be:
~Fossil B is most likely older than Fossil A.~8. The statement that could be used to explain the similarity of the developmental process of vertebrate embryos would be:
~All vertebrates develop a backbone that protects the spinal cord.~9. The term for the remains, imprints, or traces of living things from a previous geological age would be:
~Fossils~10. The reason some mutations, or changes in the sequence of DNA, don't have any effect on the characteristics of the organisms would be:
~The mutated sequence still codes for the same amino acid.~11. What is typically studies when analyzing not-yet-born (or unhatched) animals is:
~embryological development.12. What scientists can analyze to get a better understanding of how plants and animals evolved from a common ancestor is:
~DNA molecules~13-16. The rest of the questions are written responses, 13-15 being short answers and the last being a single 3-5 sentence response. But no fear! These are rather easy ones to do by yourself. Or, if you really need help, I found a lot of really helpful responses on here. Anyways, good luck!
How does sugar cross the cell membrane to get into a cell?
Answer:
Glucose cannot move across a cell membrane via simple diffusion because it is simple large and is directly rejected by the hydrophobic tails. Instead it passes across via facilitated diffusion which involves molecules moving through the membrane by passing through channel proteins.
Explanation:
In order to identify genes that function together in genetic pathways researchers can perform modifier screens, looking for second site enhancers or suppressors of a mutant. Which of the following is the most reasonable strategy for carrying out a suppressor screen in particular?
a. analyze the DNA sequence near the mutation of interest, looking for sequences that may act as silencers.
b. identify mutations that, when crossed with the original mutant, result in synthetic lethality.
c. mutagenize the original mutant and look for new mutations that reduce the severity of the original mutant phenotype.
d. screen for enhancer-trap strains that show gene expression differences in the original mutant.
e. isolate mutants with phenotypes similar to the original mutant phenotype and then cross the mutants to identify the affected genes.
Answer:
c. mutagenize the original mutant and look for new mutations that reduce the severity of the original mutant phenotype.
Explanation:
A suppressor screen is a technique employed to identify a second mutation (i.e., a suppressor mutation) capable of reverting/alleviating the phenotypic effects associated with an initial mutation. There are two types of mutants obtained from this approach: 1-Intragenic suppressors, which involve second mutations inside the gene that restore the original function of the mutated gene; and 2- Intergenic suppressors, also known as extragenic suppressors, which involve second mutations in a gene that is distinct from the original mutated gene (usually extragenic suppressors function in the same signaling pathway as the original mutated gene).

gregor Mendel demonstrated that then Heritance of genetic traits determined by
Answer:
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

How do endoparasites survive inside the body of the host?
Endoparasites have extreme specialisations which makes their life cycles more complex. Some examples of endoparasites are Taenia solium and Fasciola hepatica (liver fluke), etc.
The special structures possessed by endoparasites are as follows:
➥ Hooks .
➥ Dorsoventrally flattened body.

7. Once anaerobic respiration takes place, are the effects permanent? Why or why not?
If a tutor can give me the answer that would be very helpful
Once anaerobic respiration takes place, the effect is not permanent. When enough oxygen is available, the cell uses the oxygen to oxidise the glucose.
What is anaerobic respiration?In anaerobic respiration, oxygen is not used for the oxidation of glucose, and as a result, very little energy is produced. Glucose undergoes glycolysis and forms pyruvate. Without the presence of oxygen, lactic acid and ethanol are formed from the glucose.
When a person runs too fast, he can't breathe properly, and muscle cells don't get enough oxygen. Due to this, glucose undergoes anaerobic respiration and forms lactic acid. As less energy is produced, more is required by the cell, and a muscle cramp takes place.
When the person gets enough oxygen, this process will reverse as the cells get enough oxygen to completely oxidise the glucose. Due to the lactic acid formation in muscles, the blood pH declines, making the blood acidic.
Hence, when enough oxygen is available, this effect of anaerobic respiration will reverse.

Describe how the lactic acid produced in muscle cells enters the blood
Answer:
Explanation:
Fast-twitch muscle also uses glycolysis to produce energy, but it skips harvesting energy from pyruvate, a process that takes oxygen. Instead, pyruvate gets converted into a waste product, lactic acid, and released into the bloodstream
Answer: Lactic acid is produced in your muscles when you perform strenuous exercise. It’s produced mainly in muscle cells and red blood cells when the body breaks down carbohydrates for energy when oxygen levels are low. These levels decreases during intense exercise or when a person has an infection or disease.
