Explain How are speed and pressure of a fluid related?

Answers

Answer:

The higher the velocity of a fluid (liquid or gas), the lower the pressure it exerts. This is called Bernoulli’s Principle. Fluid pressure is caused by the random motion of the fluid molecules. When the fluid speeds up, some of the energy from that random motion is used to move faster in the fluid’s direction of motion.

what significant role does dna play in formation and development of an organism

Answers

Answer:

DNA contains the instructions needed for an organism to develop, survive, and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

Explanation:

DNA contains the instructions needed for an organism to develop, survive, and reproduce.

What is DNA?

Cells' capacity to store, retrieve, and translate the genetic instructions necessary to create and maintain a live organism is essential to life.

This genetic material is transmitted from one generation of an organism to the next through the reproductive cells of the organism and from one cell to its daughter cells during cell division.

Every living cell contains these instructions as part of its genes, which are the information-containing components that define the traits of a species as a whole and of the individuals within it.

Therefore, DNA contains the instructions needed for an organism to develop, survive, and reproduce.

Answers

D. Muscle tissue.
Hope it helps

The type of tissue which produces the movement is known as Muscle Tissue. The correct option is D.

Muscle tissue is made up of cells that have the unique ability to shorten or contract in order to move bodily parts. The tissue is densely cellular and rich in blood capillaries. Because the cells are long and slender, they are sometimes referred to as muscle fibers, and they are typically organized in bundles or layers surrounded by connective tissue.

Actin and myosin are muscular proteins found in muscle. Skeletal muscle tissue, smooth muscle tissue, and heart muscle tissue are the three types of muscle tissue.

Simple organic molecules combine to make larger molecules. Which statement best describes the disruption of the bond between two carbohydrate monomers? (3 points) Dehydration synthesis will remove water molecules, forcing the bond to break. Energy will be stored in the bond between monomers through hydrolysis. The bond in the complex carbohydrate will be broken due to enzyme activity. The helium and hydrogen atoms in the backbone of the sugar will be broken.

Answers

Answer:

The correct answer is - The bond in the complex carbohydrate will be broken due to enzyme activity

Explanation:

Carbohydrates are macromolecules formed by the combined simple monomer subunits to make a larger subunit or chain of molecules. Dehydration synthesis is the process required for the build-up of these larger molecules and for this they require energy.

The hydrolysis reaction is used to break the hydrogen bond of these monomer backbones by the addition of water which releases energy. Complex carbohydrates are digested or the bonds present in between their monomers are broken down due to the activity of the series of the enzymatic reaction.

Answer: The bond in the complex carbohydrate will be broken due to enzyme activity.
