blastocyst The most versatile stem cells occur earliest in life. As a fertilized human egg divides, it first becomes a solid ball of cells, the morula. Next, about five days after fertilization, it becomes a hollow ball, the blastocyst. The cells of the outer layer of the blastocyst eventually form part of the placenta.
What else can I help you with?
What is the mass of stems cells produced in the first few days after fertilization called?
basal stem cells.
How often do blood cells die?
Red blood cells typically live for about 120 days, while white blood cells have varying lifespans depending on the specific type. Platelets, another type of blood cell, live for about 8-9 days on average. When blood cells die, they are cleared from the bloodstream and replaced by new cells produced by the bone marrow.
What is the mass of stem cells produces in the first few days after fertilization called?
A morula (mulberry) is an early stage in the development of the embryo at which it consists of a solid spherical ball of apparently identical cells. The morula stage is when one of the earliest prenatal diagnostic test can be carried out, by removing a single cell (blastomere) and carrying out genetic diagnosis on its DNA. Each one could develop into a complete animal (or human) since they are genetic the same.
How fast is human blood made?
Human blood is constantly being produced in the bone marrow at a rate of about 100 billion cells per day. It takes about 120 days for a red blood cell to go from production in the bone marrow to circulation in the bloodstream. White blood cells have a shorter lifespan and are constantly being produced in response to the body's immune needs.
What is the replacement rate of sperm cells?
The replacement rate of sperm cells in the human body is approximately 1,500 per second. Sperm cells are constantly being produced in the testes through a process called spermatogenesis to maintain fertility.

Milk produced by cows first days after delivery?
Colostrum.
The organism grew exponentially At first it had 1200 cells After two days it had 3000 How many cells will it have after five more days?
15,800. Do the math. I certainly shouldn't be doing it for you.
Milk that is rich in protein and antibodies and produced in the first few days of lactation is termed?
Colostrum.

Where in a human do you find red blood cells?
Red blood cells are found in the bloodstream, circulating throughout the body to transport oxygen to tissues and remove carbon dioxide. They are produced in the bone marrow and have a lifespan of about 120 days.
What is the replacement rate of sperm cells?
The replacement rate of sperm cells in the human body is approximately 1,500 per second. Sperm cells are constantly being produced in the testes through a process called spermatogenesis to maintain fertility.
How long does the average red blood cell live in your body for?
120 days for a normal rbc. a sickle cell lasts only about 20 days
What is the life span of a natural killer cell?
Natural killer cells have a short life span, typically ranging from a few days to a couple of weeks. They are continuously produced by the body to maintain immune surveillance and respond rapidly to infections or malignant cells.
