What animal has a nucleus?
Most animal cells (except for human red blood cells and some others) have a nucleus. It is like a control centre in the cell which allows some substances to enter and others substances to leave the cell. It also initiates chemical reactions and processes like respiration in the cell cytoplasm.
What cells do human beings have?
some heal,conquer,breaks unwanted substances,make energy fuel,stores useful sustances and some control we need them to make our body well-functioned
What are some types of human cells?
blood cells, white blood cells, sperm cells, brain cells.
What is smaller than human cell in the human body?
All cells are smaller than human(except when you're comparing a chicken egg to an embryo)
Blood cells are produced in?
The production of blood cells is called hematopoeisis, and it is the process by which all the different blood cells are formed from a single kind of hematopoeitic stem cell. All of the body's blood cells start out in medullary portion of bone--the marrow--except in some fetal stages and in some disease states, where blood cells can be produced in the liver and spleen (this is called extramedullary hematopoeisis). Most of the cells produced in the bone marrow mature into their final forms in the bone marrow, but some white blood cells finish maturation in the thymus. The stem cells and their progeny (daughter cells) receive various stimuli in the form of chemicals that contact them that "push" them in the direction of forming whatever blood cells the body happens to need.
How human chromosomes in sex cell can be damaged by alcohol?
The Alcohol has some toxic substances that affect the sex cells that may lead to structural aberrations(diseases in sex cells).

What type of cells protect the neurons in the central nervous systems from some substances in the blood?
Could one conclude that Ependymal cells & Oligodenrocytes blood cells in the CNS protects neurons from some blood substances in blood.

What lets substances like food and oxygen diffuse into body cells?
The semi-permeable membrane in cells. Allows some substances to go through and not others.
What are Cells that let some substances in keep others out let some substances out?
The cell membrane controls what comes in and out of cells.
Some human inherited traits are transmitted by Blood cells Bone cells Sperm cells Liver cells?
Some human inherited traits are transmitted or passes from parent to offspring by sperm cells.
What is the property that allows only some substances in and out of cells?
The permeability of the cell membrane controls which substances may pass in or out of the cell.
Does a nerve call and a muscle cell of a particular organism have different numbers of chromosomes?
Every single cell minus monoploid cells (sperms and eggs) in the human body have the same number and same chromosomes. These are all diploid cells (2N). In a human, that means they have 46 chromosomes. These cells are produced through mitosis. Cells produced through meisosis are monoploid (N) and in a human have 23 chromosomes. This is generally true for all species, most having 2N in number. Some go though alternation of generation, some are N in number throughout the body (drone bees), and seeds have 3N numbers.
Why is the human body can not function with out human cells?
Without cells a human body can't function.
What are some types of human cells?
blood cells, white blood cells, sperm cells, brain cells.
