Answer:

A- Flagella

Explanation:

A flagella is a tail-like structure that helps some single celled organisms move. The descriptions for Pseudopodia and Cilia are switched, therefore it can only be answer A

Describe Newton’s second law of motion. In your response, discuss how an object’s mass or the force that is exerted on the objec
Ann [662]

Answer:

Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. The greater the force that is applied to an object of a given mass, the more the object will accelerate.

Explanation:

For example, doubling the force on the object doubles its acceleration.

Example 1: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.

likoan [24]

The salivary glands, stomach, and pancreas secrete<u> lipase enzymes</u> to break down triglycerides into monoglycerides, fatty acids, and glycerol.

Lipases are a set of water-soluble enzymes that hydrolyze substrates such as triglycerides and phospholipids, have a similar structure and are essential in the metabolism of lipoproteins and lipids.

That is, the function of lipase enzymes is to hydrolyze triglycerides to generate diglycerides, monoglycerides, fatty acids and glycerol.

<u>About lipase enzymes</u>:

  • It acts on the neutral fats in the diet, splitting them into triglycerides or diglycerides and these to monoglyceride, which is the most easily absorbed fatty compound.

  • The action of lipase is much more manifest on triglyceride, and it is also much faster the higher the molecular weight of the fatty acid present.

  • It acts on the surface and in an aqueous medium, the emulsifying agent represented by bile salts is essential for optimum effectiveness.

  • They are widely distributed, with a presence in the animal and plant kingdoms and even in the simplest unicellular organisms.

Therefore, we can conclude that the salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.

In Avery's experiment, he used DNase, RNase or proteinase to treat the heat killed S strain to see what component in the debris
nevsk [136]

Answer:

S strain

Explanation:

The Avery experiment demonstrated DNA is the genetic material. It expanded upon the findings made by Griffith.

They used Pneumococcus; Smooth strain which was virulent and the Rough which was not.

Cultures of heat killed smooth strain were prepared after which it was treated with DNases ,RNases and Proteinases to remove DNA, RNA, and proteins respectively. It will then be introduced to living Rough strain.

When treated with RNases only the RNA will be destroyed and transformation will take place leading to colonies of S stains being formed.

Only when treated with DNase did the colonies S strain fail to be formed.
