Determining the age of an object is the right answer.  

Carbon-14 isotope or the radiocarbon dating is a technique for concluding the age of an article containing organic element by applying the characteristics of radiocarbon, a radioactive isotope of carbon. Willard Libby in the 1940s invented this method of solving the issue of dating for objects containing the organic element.

Describe how cohesion and adhesion contribute to the upward movement of water through a plant.
Lilit [14]

Answer:

Both Cohesion and adhesion play an important role in the upward movement of water through a plant.

Explanation:

Water is absorbed by the roots and transported by xylem tissue to various parts of a plant body such as stem ,leaf .

                  During the transportation of water molecules through the xylem tissue formation of hydrogen bond occur between the water molecules. A single hydrogen bond is weak but collectively they exert a very strong interaction.As a result a water column is established in the xylem tissue. This is called cohesion.

                    Adhesion deals with the interaction of water column with the wall of the xylem tissue.

Pseudohypertrophic muscular dystrophy is a human disorder that causes gradual deterioration of the muscles. Only boys are affect
andriy [413]

The answer is; C

It is caused by the recessive allele because the parents appear normal but are carriers of the disorder (meaning they are heterozygous for Pseudohypertrophic muscular dystrophy). Only when the offspring is heterogenous recessive do they display the disorder.

The disorder is also sex-linked because it tends to affect only boys. This means that the disorder is probably coded for by alleles in the Y- chromosome that determines the male sex.

Za jakie czynności organizmu odpowiada układ współczulny a za jakie przywspółczulny?
nadezda [96]

Answer:  the question is <u>What activities of the body are responsible for the sympathetic nervous system and for which parasympathetic? </u>

is it right thats what the question means?

answer in eng: The sympathetic division initiates the fight-or-flight response and the parasympathetic initiates the rest-and-digest or feed-and-breed responses. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility.

answer in polish: Podział współczujący inicjuje reakcję walki lub ucieczki, a przywspółczulny inicjuje reakcje odpoczynku i trawienia lub karmienia i rozmnażania. Współczulny i przywspółczulny układ nerwowy jest ważny dla modulowania wielu funkcji życiowych, w tym oddychania i kurczliwości serca.

The cell's series of tunnel-like membranes functioning in transport and storage are the?
schepotkina [342]

The cell's series of tunnel-like membranes functioning in transport and storage are the Endoplasmic Reticulum.

What are the functions of the Endoplasmic Reticulum?

In both plant and animal cells, the endoplasmic reticulum is a network of tubules and flattened sacs that perform a number of tasks.

The structure and function of the two ER regions are different. Ribosomes are affixed to the cytoplasmic side of the membrane in rough ER. Ribosomes are not linked to smooth ER. The smooth ER is often a tubular network, whereas the rough ER is a collection of flattened sacs.

Rough Endoplasmic Reticulum (RER)

Endoplasmic Reticulum in rough shape. Membranes and secretory proteins are produced in the rough endoplasmic reticulum. Protein synthesis is carried out by translation on the ribosomes affixed to the rough ER. The rough ER generates antibodies in certain leukocytes (white blood cells). The rough ER creates insulin in pancreatic cells.

Smooth Endoplasmic Reticulum (SER)

The production of carbohydrates and lipids is one of many tasks performed by the smooth ER. Cell membranes must be built using lipids like cholesterol and phospholipids. Vesicles that deliver ER goods to various locations also use Smooth ER as a transitory place.

Hence, the correct answer is the Endoplasmic reticulum.
