Answer: Edith Widder uses the bioluminescence (light) produced by the different sea creatures to identify their various species. For example, during her talk, she mentions a fish with a headlight behind its eye that retracted like a Lamborghini’s headlight. She also describes a Christmas tree fish where everything lights up, including the jewel-like organs in its body.
Explanation: This question comes from the TED talk "Glowing life in an underwater world" by Edith Widder. During her talk, she vividly describes her experience seeing sea organisms that display bioluminescence in the ocean.

Explain the mechanisms by which sex-linked
diseases are inherited.
Answer:
Sex-linked diseases are passed down through families through one of the X or Y chromosomes. X and Y are sex chromosomes. Dominant inheritance occurs when an abnormal gene from one parent causes disease, even though the matching gene from the other parent is normal. The abnormal gene dominates.

Sex-linked diseases are passed down through families through one of the X or Y chromosomes. X and Y are sex chromosomes. Dominant inheritance occurs when an abnormal gene from one parent causes disease, even though the matching gene from the other parent is normal.
The common grackle is a species of robin-sized blackbirds that are fairly common over most of the
United States. Suppose that long tails (L) were dominant to short tails (1) in these birds. A female short-
tailed grackle mates with a male long-tailed grackle that had one parent with a long tail and one parent
with a short tail. What is the tail length probability of their offspring?
Answer:
Long tail (Ll) = 1/2 or 50%
Short tail (ll) = 1/2 or 50%
Explanation:
This question involves a single gene coding for tail length in grackle birds. The allele for long tails (L) were dominant to short tails (l) in these birds. This means that a bird that is heterozygous (Ll) for the gene will be phenotypically long tailed.
According to the question, a female short-tailed grackle (ll) mates with a male long-tailed grackle that had one parent with a long tail and one parent with a short tail. This male grackle will have a genotype: Ll because of his parental genotype. Hence, crossing ll × Ll, the following gametes will be produced by each parent:
Ll (male) = L and l
ll (female) = l and l
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Ll, Ll, ll and ll
2 Ll out of 4 are long-tailed i.e 1/2 or 50% probability
2 ll out of 4 are short-tailed i.e 1/2 or 50% probability
When HIV infects a cell, it uses the host’s cell organelles to make more HIV
viruses. Which of the following is TRUE about the cell organelles used by
HIV/AIDS virus?

proteins by rough endoplasmic reticulum and modification of
newly synthesized HIV-membrane proteins is done by Golgi
apparatus.
B)All cell organelles including ribosomes, Rough and smooth
endoplasmic reticulum and vesicles are used to synthesize one type
of viral protein.
C) Only ribosomes are used by the virus for protein synthesis.
D)Nucleolus is used by the virus essentially to enhance the rapid
production of ribosomes to ensure more protein synthesis.
what do you see inside the cell? three chromosomes three sister chromatids three homologous pairs of chromosomes three homologous pairs of chromatids
Answer:
three homologous pairs of chromosomes
Explanation:
Inside the cell we can see three homologous pairs of chromosomes as in humans there are 23 pair of homologous chromosomes and they are very similar in size and shape.
Three chromosomes are not possible to see because there are only two chromosomes and if anyone is having three chromosomes then the person is suffering from down syndrome having 47 chromosomes.
Three sister chromatids is also not possible because only two sister chromatids are found after DNA replication.
Three homologous pairs of chromatids is also not possible because chromatids are not found in pair and sister chromatids are called homologous chromosomes.
Hence, the correct answer is "three homologous pairs of chromosomes".
Why do individuals with recessive
traits show up with less frequency
in populations?
A. There are more dominant alleles in most
populations.
B. Individuals must inherit two copies of a
recessive allele to show the trait.
C. Recessive traits greatly outnumber dominant
traits in most populations.
The individuals with recessive traits show up with less frequency in populations because the individuals must inherit two copies of a recessive allele to show the trait.
What is an allele?"They are the alternative forms of a gene."
What is a recessive trait?It is a trait that is expressed only when the both alleles in the genotype are recessive.The genotype should be homozygous recessive for the trait to appear.What is a dominant trait?A dominant trait is a trait that is expressed even when one parent contributes the dominant allele.It is expressed when the genotype is heterozygous dominant or homozygous dominant.To learn more about recessive, dominant, and populations here,

Fossil evidence can be used to determine the degree to which different organisms are related. The relatedness of organisms can also be determined by examining
A. internal and external anatomical features of the organisms.
B. ancestors that the organisms share in common.
C. chemical processes that occur within the organisms.
D. all of these
Answer:
D
Explanation:
The relatedness of organisms can also be determined by examining internal and external anatomical features of the organisms, ancestors that the organisms share in common and chemical processes that occur within the organisms. Therefore, option (D) is correct.
What are anatomy characteristics?Human anatomy is characterized by reproduction, inheritance, cellular organization, growth and development, response to stimuli, evolutionary-adapted traits, and metabolism.
Anatomical characteristics that are shared by multiple organisms as a result of a common ancestor are known as homologous structures. Homologous structures, or homologies, are the tetrapod limbs.

Name the reproductive parts of an angiosperm. Where are they located? Explain in brief the structure
of its female reproductive parts with labeled diagrams.
Answer:
Stamen is the male reproductive part and the pistil is the female reproductive organ.
Explanation:
Stamen or androecium is the male reproductive part and the pistil or carpel or gynoecium, is the female reproductive organ of an angiosperm. Both are located in the flower of a plant. In flower, male reproductive part is present in the form of pollen located at certain height and the female part is located lower side so that the pollen falls on the stigma and reaches to the ovary where female cells or ovules is present that fused with pollen produces seed.
