Answer:

Law of Segregation

Explanation:

  • A gene constitutes two alleles (alternative forms of gene) located on the same location or locus on the homologous chromosomes.

Law of Segregation:

  • Mendel's Law of Segregation states that both of the alleles of a gene segregate separately into gametes i.e. each gamete randomly receives one of the two alleles.
  • Upon fertilization,  the gametes combine to form a diploid cell (zygote) that contains one allele from each parent.

Answer:

Evolution.

Explanation:

The unique method of locomotion in octopus has been utilized by successive generations of octopus through the process of evolution. Evolution is defined as the change in the characteristics of a species over several generations. This type of behaviour is attain by octopus in order to save itself from its predators such as shark so we can say that this unique method of movement is used by octopus to save itself from the predators leads to evolution in the octopus.

In the snail cepaea nemoralis, an autosomal allele causing a banded shell, u, is recessive to the allele for an unbanded shell,
Alex Ar [27]
There will be no recombinant progeny in absolute linkage. The F1 inherted banded and yellow alleles (BBCY) together on one chromosome from the banded yellow parent and unbanded and brown allels (BOCBw) together on the homologous chromosome from the unbanded parent. All the F1 gametes will contain only these two allelic combinations, in equal proportions if there is no recombination. F2 cross progeny will have 1/2 banded, that is yellow and 1/2 unbanded brown.

Describe how advances in DNA technolgy are assisting the work of those in medical fields
shutvik [7]

Answer:

Advances in DNA technology have allowed for treatments such as gene therapy in the medical field. Nowadays, there are tools like the CRIPSR-Cas9 - harnessed from bacteria's immune system- that can nip a ‘bad’ region of DNA, which is responsible for disease, and replace it with a proper functioning bit. This is how genetic disorders are going to be addressed in the near future in mainstream medical facilities.

Recombinant DNA technology is being used to create clones of transgenic organisms that produce products of significance in the medical fields. An example is incorporating the insulin gene in bacteria genome. These clones of modified bacteria colonies secrete insulin protein that is purified and injected in diabetic persons to lower their sugar level to normal.

Answer:

Saliva lubricates and moistens these food particles

Explanation:

As teeth help to break down large pieces of food into lots of smaller pieces, saliva is released and mixes with the smaller food pieces. Saliva lubricates and moistens these food particles such that a ball-like mixture of food and saliva that is known as a bolus is formed, which can then be easily swallowed.
