Which structure in the heart'separates
oxygenated blood from deoxygenated blood?
Answer:
pericardium
Explanation:
A double-walled membrane, the pericardium, separates the right and left chambers, preventing oxygen-rich blood from mixing up with the one without oxygen. So, the heart functions go smoothly. Deoxygenated blood enters the right atrium.
Explain why short bursts of light during the dark period caused the Xanthium strumarium plant to not grow.
Answer:
Due to stoppage of reactions.
Explanation:
The short bursts of light during the dark period is responsible for no growth in the Xanthium strumarium plant because this short bursts of light affected the darkness which is required by the Xanthium strumarium plant for its growth. If there is no burst of light occurs, the Xanthium strumarium plant will grow normally but when Xanthium strumarium plant receives the bursts of light, the chemical reactions that needs darkness will stop and as a result no growth occurs.

Explanation:
A farmer often sprays a certain kind of insecticide, a chemical that kills insects, on his plants to prevent locust bugs from eating all of his corn crops. One day there was a random change in the sequence of DNA in a locust egg cell. When the egg cell hatched, the locust was resistant to the insecticide (it would not be killed by it). Since that locust could survive and reproduce, natural selection occurred until the entire population evolved to become resistant.
A) Identify the variation that existed in the insect population. _________________________________
B) Identify the process that created this variation. _________________________________
C) Explain why the variations in the insect population would be passed on to the next generation.
D) Is this locust population likely to survive, why or why not?
Answer:
as they were living in that environment they adopted it and were able to in it ; the population was able to survive because they adopted it
Which of the following statements about lichens are true?
Answer:
The photobiont supplies the association organic carbon from photosynthesis, and the mycobiont ensures protection and regulates the supply of minerals and water. The nutritional exchange between partners is probably much more complex than exchange of water and minerals for organic carbon. Thus, the correct answer is option B.

What human behavior was the cause of the Nipah virus outbreak in Bangladesh? How did scientists determine this?
Answer:
Humans drinking raw date palm sap was the cause of the Nipah virus outbreak in Bangladesh. Scientists found Nipah virus in bat excretions and discovered that bats were contaminating date palm juice with their excretions (saliva, urine).
Explanation:
Nipah virus can spread to people from:
1) Direct contact with infected animals, such as bats or pigs, or their body fluids (such as blood, urine or saliva).
2) Consuming food products that have been contaminated by body fluids of infected animals (such as palm sap or fruit contaminated by an infected bat).
How can alleles show incomplete dominance?
Answer:
a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both alleles. It is also called semi-dominance or partial dominance.

1. Describe the classical scheme of gene expression from DNA to RNA to protein.
2. Explain DNA replication and recombination.
Answer:
1. The central dogma of molecular biology is DNA >>transcription>> RNA >>translation>> protein
2. DNA replication refers to the genetic process of generating two identical DNA molecules from one DNA sequence. Recombination refers to the exchange of genetic material (DNA) between non-sister chromatids during cell division (meiosis)
Explanation:
Gene expression (also known as transcription) is the process by which a specific fragment of DNA called gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA), which is in turn used as template to create a protein. This final product (i.e., the protein) has an effect on the phenotype of the individual. The DNA template is a single-stranded ordered polynucleotide chain composed of four different types of nitrogenous bases: Adenine, Thymine, Guanine and Cytosine. In the complementary RNA molecule, Thymine bases are replaced by Uracil bases. Moreover, DNA replication refers to the process by which cells duplicate their genetic material before cell division (either mitosis or meiosis). During this process, both DNA strands are separated and each one is used as a template to synthesize a new DNA molecule. Finally, recombination or crossing over is a process where non-sister chromatids exchange genetic material during meiosis I (Prophase I). Recombination is known to increase genetic variation in resulting meiotic cells.

A) It changes how genes code for antigens.
B) It leads to less mRNA which is easier to copy.
C) It creates a variety of immune responses in the host organisms.
D) It makes them unrecognizable to the immune system.
Answer:
1. Individuals with thicker fur had a survival advantage in the cold environment, allowing these individuals to reproduce more often and create more offspring.

3. The green skin color is being selected over blue skin color.
4. DNA
5. They show intermediate steps in the evolution process.
6. Different islands had very different food resources available, and only individuals that were adapted to eat those food resources survived and reproduced on that island.
7. Those who have traits that help them survive are able to reproduce, and their offspring have those traits, leading to a change in the species over time.

The answer is C.
Explanation:
This is because for A, this statement says nothing about corundum being yellow which means that this doesn’t apply and is incorrect. For B is pretty much the same as A, this statement about corundum doesn’t say anything about it being able to flavor or being flavorful. Lastly for D, the fact that corundum is hard means it would be impractical and probably impossible to use it as pencil lead because, all lead it doing with a pencil is being crushes and ground into the paper as you write.

Which factors were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection?
(1 point)
1. a change in the diet of human populations as they settled in colder climates
2. the clothing worn by humans in the early 8th century
3.the interaction of human populations with predators in colder climates
4.the impact of UV radiation on folate and Vitamin D levels in human populations
Answer: The answer is 4
Explanation:
Vitamin D controls your skin pigment. It's kind of like when someone has an iron deficiency they get bruises and they turn a whiter shade.
Hope I helped :)
The factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection are the impact of UV radiation on folate and Vitamin D levels in human populations.
Ultraviolet B radiation produces diet D in human skin. Ultraviolet radiation can, however, smash folate. Folate is critical for the speedy increase of cells, particularly at some point in which its deficiency can motivate neural tube defects. The human frame additionally has a mechanism to save you overproduction of vitamins.
What is UV radiation?Ultraviolet is a shape of electromagnetic radiation with a wavelength from 10 nm to four hundred nm, shorter than that of seen light, but longer than X-rays. UV radiation is found in sunlight and constitutes approximately 10% of the whole electromagnetic radiation output from the Sun.
Thus it is learned that the above answers are well-explained factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection bout.
