Biology

Answer:

Artwork: How radio waves travel from a transmitter to a receiver. 1) Electrons rush up and down the transmitter, shooting out radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the radio waves hit a receiver, they make electrons vibrate inside it, recreating the original signal.

Chromosomes and DNA

Chromosomes are DNA wrapped around proteins to form an X-shaped structure.



The diagram will help you see the relationship.

1. Chromosomes are found in the nucleus
2. Chromosomes are made of DNA
3. Sections of chromosomes are called genes



DNA - deoxyribonucleic acid (it is the genetic code that contains all the information needed to build and maintain an organism)





Chromosome Structure







Chromosome Numbers

Each organism has a distinct number of chromosomes, in humans, every cell contains 46 chromosomes. Other organisms have different numbers, for instance, a dog has 78 chromosomes per cell.

Somatic Cells - body cells, such as muscle, skin, blood ...etc. These cells contain a complete set of chromosomes (46 in humans) and are called DIPLOID.

Sex Cells - also known as gametes. These cells contain half the number of chromosomes as body cells and are called HAPLOID

Chromosomes come in pairs, called Homologous Pairs (or homologs). Imagine homologs as a matching set, but they are not exacly alike, like a pair of shoes.

Diploid cells have 23 homologous pairs = total of 46

Haploid cells have 23 chromosomes (that are not paired) = total of 23

Homologous Chromosomes



Sex Determination

Chromosomes determine the sex of an offspring. In humans, a pair of chromosomes called SEX CHROMOSOMES determine the sex.

If you have XX sex chromosomes - you are female

If you have XY sex chromosomes - you are male

During fertilization, sperm cells will either contain an X or a Y chromosome (in addition to 22 other chromosomes - total of 23). If a sperm containing an X chromosome fertilizes an egg, the offspring will be female. If a sperm cell containing a Y chromosome fertilizes an egg, the offspring will be male.

Creation of a Zygote

When two sex cells, or gametes come together, the resulting fertilized egg is called a ZYGOTE

Zygotes are diploid and have the total 46 chromosomes (in humans)

Karyotype

A karyotype is a picture of a person's (or fetus) chromosomes. A karyotype is often done to determine if the offspring has the correct number of chromosomes. An incorrect number of chromosomes indicates that the child will have a condition, like Down Syndrome

Compare the Karyotypes below













Notice that a person with Down Syndrome has an extra chromosome #21. Instead of a pair, this person has 3 chromosomes - a condition called TRISOMY (tri = three)

Trisomy results when chromosomes fail to separate - NONDISJUNCTION - when sex cells are created. The resulting egg or sperm has 24 instead of the normal 23.

Other conditions result from having the wrong number of chromosomes:

Klinefelters Syndrome - XXY (sex chromosomes)

Edward Syndrome - Trisomy of chromosome #13

Why is carbon a good atom for building macromolecules or polymers?
vlada-n [284]
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.

a client receives blood work back showing high levels of lipoproteins and low levels of low density lipoproteins
Y_Kistochka [10]
<h3>Lipoproteins</h3>

Explanation:

Lipoproteins are aggregate molecules of lipids and proteins which carry cholesterol in the blood. Cholesterol binds with water-soluble carrier molecules of the lipoproteins.

Based on their density, lipoproteins are classified as very low density lipoproteins (VLDL), low density lipoprotein (LDL), high density lipoprotein (HDL)  

The serum lipoprotein levels are diagnostic markers to detect blood fat levels and are checked in the blood lipid profile tests.

If LDL levels are increased it indicates higher risk for heart diseases like atherosclerosis  

If HDL is increased, it reflects a healthy heart and reduces the risk for heart diseases or failure
