A cross bridge cycle occurs when actin (A) combines with myosin (M) and ATP to produce force, adenosine diphosphate (ADP) and inorganic phosphate (Pi). The cross bridge cycle is a series of molecular events that occur after excitation of the sarcolemma.

A hormone released in the small intestine that stimulates the pancreas to release digestive enzymes and the gallbladder to relea
lorasvet [3.4K]

A hormone released in the small intestine that stimulates the pancreas to release digestive enzymes and the gallbladder to release bile is known as Cholecystokinin.

Hormones play a huge position for your normal functioning. They manage heart rate, sleep cycles, sexual feature, and replica. Your metabolism, urge for food, growth and development, temper, strain, and body temperatures are all suffering from hormones.

Cholecystokinin is secreted by using cells of the upper small gut. Its secretion is stimulated by using the advent of hydrochloric acid, amino acids, or fatty acids into the belly or duodenum. Cholecystokinin stimulates the gallbladder to settlement and launch stored bile into the gut. Cholecystokinin (CCK) is produced more often than not inside the duodenum and the jejunum. The physiological roles of CCK are the stimulation of pancreatic secretion and the contraction of the gall-bladder. Secretin and CCK are peptide hormones secreted via the endocrine cells inside the gastrointestinal tract. Secretin stimulates the secretion of water and bicarbonate ions from the pancreas, while CCK stimulates the synthesis and secretion of bile juice and pancreatic enzymes.

Let p = purple flowers and p = white, and t = tall plants and t = dwarf. if the uppercase letters represent the dominant alleles
sesenic [268]

If the uppercase letters represent the dominant alleles, purple flowers and tall are the phenotype of a plant with the genotype Pptt.

A gene can exist in different forms across organisms. These different forms are known as alleles.

The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.  

Examples of  genotype include:

  • Hair colour
  • Height
  • Shoe size
  • Eye colour

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.

Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including:

  • Epigenetic modifications
  • Environmental and lifestyle factors

Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex.

Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences.

If hunting continues and drastically reduces the deer population, how might this impact the hawk population?
laiz [17]
Well, considering if the deer and the hawk have a direct predator prey relationship, where the deer are the prey, then the hawk population will also drop quite a lot, unless they have some other major food sources, but chances are they'll still drop.

If it's NOT a direct predator prey situation, for example: The deer happen to eat something that the hawks also eat, or the deer are prey for something the hawks eat:
If the deer eat something the hawks eat, by them dropping it means there will be more food supply for the hawks, meaning as the deer population drops, the hawk population will go up.

If the deer are PREY to something the hawk eats, then by there being less deer, then whatever the primary consumer of the deer is will also drop. If the hawk eats that predator, then there will be less of those predators, and less prey, meaning the hawk population will still drop

You were most likely given a food web to look at. Seeing how you didn't post that, I just gave you the only 3 situations that could happen.

~Hope this helps!
