The simplest answer would be to look at a punnet square. it gives you the random chance that a trait gets passed on to offspring. it's made off probability of dominant and recessive genes. But it's random in the end.

Answer: Alleles are sorted randomly into sex cells.

Explanation:

Random means that each item has an equal probability of being chosen.  

According to Mendel's two laws:

  • 1st Law, the principle of segregation: Alleles (the two forms of a gene pair) segregate from each other in the formation of gametes.
  • 2nd Law, the principle of independent assortment: Genes for different traits assort independently of one another in the formation of gametes.

During meiosis, crossing over occurs, which consists of the exchange of alleles between chromosomes. This happens at random and in this way, in each meiosis, totally<u> new chromosomes are created. Then, the two chromosomes separate and end up in the newly created gametes</u>. <u>So which of the alleles goes into which gamete created is random. And after that, which sperm fertilises which egg is also random.</u>

Whales were hunted nearly to extinction primarily for their blubber, which was burned in oil lamps to light buildings. Whale oil
Arada [10]

Answer:

This is unethical.

Explanation:

Every creature contributes one way or the other to the existence of  ecosystem,and the   stabity of the biodervasity. The whale is one of the major componets of the aquatic biodiversity .Therefore continous killing whch may lead to extinction  would distablized rthe bioderstiy and leads to the loss of ecosystem.

Besides,if whales goes into exticntion this would  affet  the future generations to learn from  their existence?Therefore for preservation for future generations,they must be protected for extictinon.

The advent of  biotechnology,has shown the genetic products of human and  animals could be used to produce genetically modifjed product for humanity Thus if whale goes into exticntion this may not be possible.

Which of the following is not a true statement regarding the genetic code?
padilas [110]

Answer:

E. Each codon represents a different amino acid.

Explanation:

The genetic code refers to the set of rules guiding the translation of nucleotide bases in DNA or RNA into an amino acid sequence (proteins). The genetic code contains all the codons in the genome, which is a group of three nucleotide base (triplet-based). Each codon species a particular amino acid, however, more than one codon can code for a particular amino acid. This characteristics of the genetic code is called DEGENERACY.

The genetic code is said to be nearly universal because the same codon encodes the same amino acid in almost all living organisms with only few exceptions. The nonoverlapping nature of the genetic code refers to the fact the three bases of a codon are read independently from the bases of another codon i.e. codons do not overlap.

A codon represents one amino acid but more than one codon can represent the same amino acid. Hence, option E is untrue

weqwewe [10]

Answer: Las plantas también proporcionan agua a través de los estomas y los animales proporcionan o liberan agua a través de la respiración, la transpiración y la micción.

Explanation: Las plantas también proporcionan agua a través de los estomas y los animales proporcionan o liberan agua a través de la respiración, la transpiración y la micción. Las plantas tienen una pequeña abertura llamada estoma por la cual la planta toma aire dentro de su cuerpo y libera agua para regular su temperatura mientras que por otro lado, los animales liberan agua de su cuerpo a través de la respiración en forma de vapores y de la micción en forma de líquido.
