A fruit fly has diploid cells with 8 chromosomes. Explain how many chromosomes are in its haploid gametes
Y_Kistochka [10]

Answer:

4

Explanation:

Diploid means 2n

Haploid means n

Here we have 2n=8 (because fruit fly has diploid cells with 8 chromosomes) to get to n which is haploid divide by 2, you get n=4

Within an organism it is critical that signals between cells are very specific.
Shalnov [3]

Answer:

The ligand has only one receptor that it is able to bind to

Explanation:

The shape of the ligand and its corresponding receptor allow there to be specificity. For example, receptors for ligand A would be found on the target immune system cells and not on cardiac muscle cells or skin epithelial cells. Therfore, even though the cardiac muscle cells or the skin epithelial cells would be exposed to ligand A, they would not be able to bind to it and therefore could not react because of the specificity of the receptor of ligand A at that moment

Which method of finding exoplanets involves directly viewing the planet through various types of telescopes?​
musickatia [10]

Answer:A star with a planet will move in its own small orbit in response to the planet's gravity. This leads to variations in the speed with which the star moves toward or away from Earth, i.e. the variations are in the radial velocity of the star with respect to Earth. The radial velocity can be deduced from the displacement in the parent star's spectral lines due to the Doppler effect

What are the 3 bases of finding the amino acid of a codon
lys-0071 [83]

The three nucleotides are the bases used to encode an amino acid of codon.

<u>EXPLANATION: </u>

Genetic code explains the bases and flow in DNA followed by the flow of amino acids present in the proteins.Proteins are usually made of 20 amino acids that has been encoded by four bases. Now, at least three bases are required to encode 20 amino acids.

Three adjacent nucleotides forms a unit called codon. Also, experiments have been done to show that the single amino acid encoded by a group of three bases. This code doesn't overlap with others and the order of flow is read sequentially without any punctuation.
