Heres a long answer,hope you don't mind :) A frog's forelegs, also called arms, contain humerus, radius and ulna bones similar to those of a human's. However, a frog's radius and ulna are fused together. Frogs' upper legs contain a femur, and its lower leg bones, the tibia and fibula, are fused together.
Frogs typically have four toes on their front legs and five on their back legs, with lengths varying by different species. Tree frogs who do a lot of climbing and aquatic frogs who require webbed toes for efficient swimming tend to have very long digits. Frogs that live in the mud typically have shorter toes that they utilize as shovels.
The skull of a frog contains five bones and it is connected directly to the spine without a neck vertebrae. At the terminus of the spine, a frog's vertebrae are fused together into a single bone. Due to the lack of ribs, a frog's pelvis is able to slide up and down its spine. This skeletal adaptation is thought to increase jumping ability.

In receptor-mediated endocytosis, which event occurs immediately after the fusion of coated vesicles with lysosomes that are fil

mixas84 [53]

The acidic environment of the lysosome and the lysosomal enzymes detach the ligands from their receptors.

Receptor-mediated endocytosis is a process in which cell surface receptors are employed for transporting substances such as proteins, hormones, and metabolites from extra-cellular matrix into the cells. Receptor-mediated endocytosis usually occurs through clathrin (a type of protein)-coated pits and vesicle and it allow only the receptor-specific substances to enter the cell. Under this process, molecule binds to protein receptors after which the receptor molecule moves to clathrin coated pits and vesicle. The cell membrane then folds inwards and there is fusion of a coated vesicle. After this, the ligands are detached from their receptors.

What is peristalsis and where does it occur?

Airida [17]

Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

Which statement is a well-written hypothesis about DDT and its effects on the environment?

Ray Of Light [21]

The statement that is a well-written hypothesis about DDT and its effects on the environment is as follows: If DDT levels in the environment increase, then the number of predatory birds will decrease (option B).

<h3>What is an hypothesis?</h3>

Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation or experimentation.

Hypothesis is widely regarded as an educated guess because it predicts the outcome of an experiment and can be tested to either be true or false.

A hypothesis is usually written as an IF, THEN statement.

Therefore, the statement that is a well-written hypothesis about DDT and its effects on the environment is as follows: If DDT levels in the environment increase, then the number of predatory birds will decrease.

The majority of triglyceride digestion occurs in the small intestine facilitated by the enzyme

bixtya [17]

Answer:

pancreatic lipase

Explanation:

Enzymes from pancreas involved in triacylglycerol digestion are called pancreatic lipases and they catalyze the partial hydrolysis of triglycerides into a mixture of free fatty acids and acylglycerols. After digestion of lipids, monoglycerides and fatty acids associate with bile salts and phopholipids to form micelles. Micelles are structures that are necessary for the transport the poorly soluble monoglycerides and fatty acids to the surface of the enterocyte. But, micelles cannot be absorbed by epithelial cell, only freely dissolved monoglycerides and fatty acids can. Free fatty acids and monogycerids can just diffuse across the plasma membrane because of their nonpolar nature.

Some absorption (e.g. for cholesterol) may be facilitated by specific transport proteins.
