Bees pollinate red snapdragons in one part of the garden then fly over to another area and pollinate white snapdragons. After a

few generations, the seeds from the white snapdragons start to produce pink snapdragons. Identify the mechanism that brought this change in gene frequencies. Select one of the options below as your answer. A. Genetic drift. B. Gene flow. C. Reproductive isolation. D. Disruptive selection.

Answer:

D. There is no enough oxygen in the culture fluid

Explanation:

The cells in the test tube need to carryout one of the important metabolic processes of living organisms - respiration. The process involves the breakdown of glucose to generate energy for other metabolic processes in the cell.

Respiration can be carried out in the presence of oxygen (aerobic) or in the absence of oxygen (anaerobic). Human cells are primarily aerobic but can carryout respiration anaerobically in the presence of inadequate oxygen.

For aerobic respiration, glucose is broken down in the presence of oxygen to produce carbon-dioxide, water and energy in the form of ATP:

C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP

<em>In the absence of oxygen, the glucose becomes converted to lactic acid and a smaller amount of ATP is produced as compared to aerobic respiration.</em>

<em>Hence, lactic acid gradually builds up in the absence of oxygen due to anaerobic respiration.</em>

The correct option is D.

How does the digestive system of poultry vary from other animals?
Vinvika [58]

Answer:

They digest without the use of teeth.

Explanation:

The food trickles from the crop into the bird's stomach (proventriculus or gizzard) where digestive enzymes are added to the mix and physical grinding of the food occurs. The gizzard is why chickens do not need teeth.

Insertion and deletion mutations are said to cause shifts in the reading gram of the mRNA. Substitution mutations do not cause t
PSYCHO15rus [73]

Explanation:

A frameshift mutation  is an insertion or deletion in a sequence of DNA which disrupts the way the code is read. It occurs when the codons undergo a disruption through the deletion or insertion of one or multiple nucleotides (given that the number removed or added are not multiples of 3) - this alters the open reading frame; the amino acids produced through translation simply occur in a different sequence.

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

  • somatic: these only occur within certain cells, and arise from environmental factors such as UV light
  • hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Hatshy [7]
Only the part of the leaf that was in the sunlight would contain starch because it absorbed light for photosynthesis however the plant that was covered was not able to absorb light because it was covered so no photosynthesis took place.
