Answer 1

Answer:

Test/Back Cross ( a method used to determine the unknown genotype of organsm by crossing it with recessive phenotype)

Answer 2

Answer:

[tex]beinggreat78~here~to~help![/tex]

The term is called a test-cross. This method is used to determine the genotype of someone whose genotype is unknown. For instance, we can see the person's eye color, which is Hazel, but we cannot identify which genotype they have because they have mixed eye colors. You would have to test or back cross to discover their genotype.

2/4 have Ee, and 2/4 have ee, ee is the attached, so the chance is 2/4, or 50%
b)
hom*zygous means that both letters are the same, so EE, or ee
the mother is EE, while the father is ee
make a table:

As you can see, it's all Ee, so the only possibility is for the child to have detached earlobes, and no attached earlobes are produced (in theory, at least)

There hope it helps!!! :)

please put me brainlist!! have a good day/night!!! ˋ( ° ▽、° ) (☞゚ヮ゚)☞

The important biochemical process that receives a supply of NAD+ ions from the fermentation process during anaerobic respiration is glycolysis. Hence option C is correct.

What is Glycolysis?

Glycolysis is the first step in both aerobic and anaerobic respiration. It takes place in the cytoplasm and involves the breakdown of glucose into pyruvate. During the process, NAD+ ions are reduced to NADH, which is an energy-rich molecule that is used in the electron transport chain to produce ATP.

In anaerobic respiration, when oxygen is not available, the electron transport chain cannot function, and the cell must rely on other processes to regenerate NAD+.

Fermentation is one such process, and it involves the reduction of pyruvate to other organic molecules, such as lactic acid or ethanol. This process regenerates NAD+ from NADH, which can then be used in glycolysis to produce more ATP.

Therefore, during anaerobic respiration, the fermentation process supplies NAD+ ions to glycolysis, allowing the cell to continue producing ATP in the absence of oxygen.

Hence option C glycolysis is correct.

Which statement best describes how organisms use DNA and amino acids to synthesize protein?
1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.
2 DNA is translated into mRNA, which is transcribed by the ribosome to produce an amino acid chain
3 Amino acids are transcribed into mRNA, which is translated into the nucleus to produce a molecule of DNA.
4 Amino acids are translated into mRNA, which is transcribed in the nucleus to produce a molecule of DNA.

Answers

Answer:

1 Dna is transcribed into mRNA, which is translated by the ribosome to produce an amino acid chain.

Explanation:

The steps of the process are always from DNA to mRNA to amino acids. This is because DNA can't travel out of the nucleus. So, DNA must be converted to mRNA to travel out of the nucleus. Only mRNA can leave the nucleus. The m in mRNA stands for messenger, so think of mRNA as the messenger from DNA to amino acids. Then the mRNA must be converted to amino acids to produce a protein.

So, options 3 and 4 are eliminated.

The process of DNA to mRNA is called Transcription. The act of transcription is called transcribing.

The process of mRNA to amino acid is called translation. The act of translation is translating.

The only option that fits this category is option 1.

Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar group are termed:.

Answers

We can confirm that Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar group are termed vestigial.

What are vestigial features?

These can be thought of as features that belonged to ancestors of a specific species and are no longer needed, and thus have been reduced to functionless vestiges through many generations of evolution. The appendix is one such example in humans.

Therefore, we can confirm that Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar group are termed vestigial.

A biologist is studying golden frogs that live in cool streams running through the rain forests of Central America. The biologist conducts a survey of the population and counts over 100 frogs in one mile of stream. The biologist returns to the same location one year later and counts only 20 frogs in that same stretch of stream. The biologist wonders why there are suddenly so few golden frogs.

The biologist also observes that a mining company has set up a copper mine only a few miles from the stream. By reading studies on copper mining operations in other parts of the world, the biologist learns that the wastewater runoff from the mines is highly acidic and contains potentially toxic compounds.

Which question most closely relates to the biologist's observations and collected data?

Are the golden frogs succumbing to a fungal infection?

Did the golden frogs migrate to a new habitat?

Why was a copper mine built so close to the stream?

Is the runoff from the copper mine contaminating the golden frogs' stream and killing the frogs?

Answers

Answer:

The most likely answer would be D, Is the runoff from the copper mine contaminating the golden frogs' stream and killing the frogs?

Explanation:

The golden frogs live either close to the stream or in it, which means the acidity and toxicity could kill them.
