What else can I help you with?
What year did Dalton say that Atoms of the same element exactly alike?
John Dalton postulated that atoms of the same element are exactly alike in his atomic theory developed in the early 19th century.
What is The cells of plants and animals are the same.?
no it is not true that plant and animal cells are exactly alike.
Why we humans look so alike but yet different?
in sexual reproduction,an offspring gets 23 pairs of chromosomes from both parent- as in meiosis cell division.therefore this lead to a differences in the genetic material through which humans were made.NOTE-DURING MEIOSIS CELL DIVISION THE CELL MAKES SURE THE PAIRS OF CHROMOSOMES FROM BOTH PARENT ARE DIFFERENT,THAT LEADS TO VARIATION WITHIN OFFSPRINGS AND PARENTS.CERTAINLY YOU DO NOT LOOK EXACTLY LIKE EITHER PARENT.FACIAL APPERANCE COULD BE THE SAME BUT NOT BEHAVIOURAL PATTERN.IT IS SHARED.
Why are the atoms in an element exactly alike in some ways but may not be alike in other ways?
they all have same number of protons and electrons (in unionized form) but may have different number of neutrons.
How are warm and cold molecules alike?
they are exactly the same in every way except the warm ones move faster
How are the gametes produced by meiosis alike?
Gametes produced by meiosis have half the number of chromosomes as the parent cell. They each undergo two rounds of cell division in meiosis to reduce the chromosome number and create genetically diverse gametes. Additionally, meiosis involves crossing over and random assortment of chromosomes, contributing to genetic variation in gametes.
Why are no two gametes exactly alike?
Each sperm and egg cell are genetically different, because during meiosis, recombination by crossing over happens. Chromosomes exchange genetic material between TWO chomatids of homologous chromosomes out of four in a bivalent. Thus 50% gametes are parental and 50% new combinations.
How is mitosis and meiosos alike and different?
Mitosis is the process in where cells are made throughout the body. The process is called IPMAT, this stands for Interphase Prophase Metaphase Anaphase Telophase Mitosis makes different cells with different functions for specific body functions except for the sex gametes. Meiosis on the other hand makes the sex gametes and its process is the same except it is repeated twice. It is called IPMATPMAT Interphase Prohase Metaphase Anaphase Telophase Prophase Metaphase Anaphase Telophase Meiosis can only make sex gametes and nothing more.
Are homologous chromosomes exactly alike?
no
Are vitamins and minerals exactly alike?
no
Can two things be exactly alike?
NO!!
When was The Man Whose Teeth Were All Exactly Alike created?
The Man Whose Teeth Were All Exactly Alike was created in 1984.
How is heredity determined?
heredity is determined by the passing down of genes from each parent, we have 46 chromosomes, 23 from each parent, this is where you get the genes to cross over during meiosis (the cell cycle of producing gametes) When crossing over occurs, it heightens the random chance of inherited traits. Each parent has their own two chromosomes to split up so this is why no one looks exactly alike or a complete mesh between the two parents. =)
How many pages does The Man Whose Teeth Were All Exactly Alike have?
The Man Whose Teeth Were All Exactly Alike has 223 pages.
Do a female and a male gray wolf look alike or different?
They can look alike but, they don't look exactly alike. No two of any species are exactly the same.
Do female and male star tortoises look alike?
They are very similar but not exactly alike.
Why don't any two people look alike?
there is no person that looks exactly alike but there is a such thing as a dopple ganger and that is a person that looks alot like you but not exactly .
