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 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.

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.
➥ High reproductive potential.
➥ Indirect development.

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.

Human blood type is determined by three alleles IA, IB, and IO. The alleles IA and IB are co-dominant to each other, and both are dominant to IO. Within a large, randomly mating population (540,000 individuals), the frequencies for the blood type alleles are 0.3 for the IA allele, 0.6 for the IO allele, and 0.1 for the IB allele. What percentage of the type A people are heterozygotes (IAIO)?

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).

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.

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.

What happens if mutations are not corrected
Answer:
A mutation cannot be corrected and can either harm, benefit or be neutral in an organism
Explanation:
A common gene mutation could be Cancer, this is a highly severe gene mutation that can cause a multitude of complications to an organism when left untreated. Some mutations such as Heterochromia, an eye mutation causing two different colored eyes, cause no harm, but makes the organism look more unique.
