Answer: Option C.

Cellulose.

Explanation:

Cellulose is a polysaccharide which is made up of glucose and it is an important component in plant cell wall. It give strength and rigidity to the cell wall. Cellulose make the cell walls strong. This play a regulatory role in tissues growth and provide strength. The cellulose is only found in cell wall and it's protect the cell wall.

Which of the following properties of carbon give it particular importance to life

olga55 [171]

I wrote a paragraph summing the importance of Carbon a while back, see if it helps find your answer. :)

Carbon is an element on the periodic table with the symbol C, and the atomic number 6. There are many reasons that carbon is vital to life on earth, not only to humans but to plants as well. First of all, humans are made of eighteen percent carbon. It is not only found in humans, it is also found in every organism currently known, including plants in a technological way. To plants, carbon flows inside of their cells. They need it to create glucose which then works as food. To humans, it's used in many science sets. It is used in a vast array of compounds including gasoline. Gasoline is what keeps motors around the world running, and it's made up of hydrocarbons with at least 5 carbon atoms each. It also aids the greenhouse effect, keeping the earth warm and habitable by human beings.

This tutorial will take you step by step through the question. Individuals with the genotypes Aa Bb CC Dd and Aa bb Cc Dd are cr

Mrac [35]

Answer:

The correct answer is -

a) 1/16

b) 1/64

c) 1/32

Explanation:

According to the law of independent assortment, each allele of a particular gene has equal chances of getting inherited into the gametes.

In a Mendelian cross of Aa x Aa would give;

AA = 1/4,

Aa = 2/4 and

aa = 1/4

The result of the cross between AaBb x AaBb would be 1/16 due to the fact that probability is still the same AA = 1/4, BB = 1/4 therefore, AABB = 1/16 = 1/4× 1/4.

Now based on this crossing the following:

AaBbCCDd x AabbCcDd.

Take each allele as individual

Aa x Aa would give; AA = 1/4, Aa = 2/4 and aa = 1/4

Bb x bb would give; BB = 1/2, bb = 1/2

CC x Cc would give; CC = 1/2, Cc = 1/2

Dd x Dd would give; DD = 1/4, Dd = 2/4 and dd = 1/4

Then the probability of progeny of the following would be:

a) the probability of AaBbCcDd = 2/4 x 1/2 x 1/2 x 2/4 = 1/16

b) the probability of aabbCCdd = 1/4 x 1/2 x 1/2 x 1/4 = 1/64

c) the probability of AabbCcDD = 2/4 x 1/2 x 1/2 x 1/4 = 1/32

Explain blood curculation in human body in brief (in 100 words)

bekas [8.4K]

Circulatory system pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.

How to identify oxygen and carbon dioxide?<br>

Genrish500 [490]

Answer:

Place a glowing splint in the test tube, and if it reignites, it could be oxygen. Place a burning splint into a test tube, and if it goes out, it could be carbon dioxide. Or, place carbon dioxide gas in limewater, and if it turns milky and gets chunks, it is carbon dioxide.

Grace [21]

Answer:Organ

Explanation:An organ may be defined as a group of tissues which perform similar functions. Organs can be found in both plants and animals,functionally related organs often cooperate to form systems. These organs are interdependent on each other to make up organ systems. Organ systems can be found in the different parts of the body. For instance,the esophagus,stomach and liver make up the digestive system and in the excretory system the skin and kidney are examples of the organs that can be found here. The main tissues of an organ tend to have the same embryological origin. This simply means that they arise from the same germ layer and by germ layer we mean the primary layer of cells that form during embryonic development. In plants however,the main organs are the roots,stem and leaves whose primary functions are to give nourishment to the plant. Reproductive organs of plants include the seed,flowers and spores which maintain the basic life processes of the plant.
