Can someone explain Meiosis 1 and II to me like I'm a baby? (i really don't understand it!) 15 pts
topjm [15]

Answer:

Meiosis 1 is when the homologous chromosomes separate and crossing over occurs. Meiosis 2 is when the sister chromatids seperate and produces 4 haploid daughter cells.

Explanation:

The phases of Meiosis 1 are, Interphase, Prophase 1, Metaphase 1, Anaphase 1, Telophase 1 & Cytokinesis.

Interphase: DNA is replicated and organic material is synthesized.

Prophase 1: Chromosomes pair up

Metaphase 1: Crossing Over occurs and chromosomes line up at the equator.

Anaphase 1: Chromosomes pull apart

Telophase 1 & Cytokinesis: Cell pinches to both sides and begins to pull apart as the cytoplasm is copied.

The phases of Meiosis 2 are, Prophase 2, Metaphase 2, Anaphase 2, Telophase 2 & Cytokinesis.

Prophase 2: Two daughter cells are formed

Metaphase 2: Chromosomes line up at equator of both cells.

Anaphase 2: Sister chromatids are pulled apart in each cell.

Telophase 2 & Cytokinesis: The cells pinch to both sides as the cytoplasm is replicated and four granddaughter cells are formed.

NEED HELP QUICK! <br><br> Suggest some reasons why Neanderthals might have become extinct.
Goshia [24]
I THINK
Neanderthals are the closest extinct relatives of modern humans, and lived in Europe and Asia. Recent findings suggest that Neanderthals were closely related enough to interbreed with ancestors of modern humans— about 1.5 to 2.1 percent of the DNA of anyone outside Africa is Neanderthal in origin

LDL (low-density lipoprotein) contains
Basile [38]

Answer:The correct answer is " a"

LDL contain protein,triglycerides,phospholipid and cholesterol.

Explanation:

Low density lipoprotein,or LDL,are complex aggregates of lipids and protein.Their function is to transport lipids (fats) around the body,in the bloodstream,and to the cells where its required.Apart from this,it also carries triglycerides,phospholipids and fat soluble vitamins.

Lipoprotein is composed of a hydrophobic core that is made up of polyunsaturated fatty acids and cholesterol molecules,along with a lipid membrane that contains protein called apolipoproteins.

There are 4 major classes of lipoprotein:

•chylomicrons

•very low density lipoprotein(VLDL)

•high density lipoprotein (HDL)

•low density lipoprotein(LDL)
