How many chromosome do human have?
Humans have 23 pairs of chromosomes; 46 chromosomes in all, 23 from the father and 23 from the mother.A normal human being has 23 chromosomes from each parent, giving them 23 pairs or 46 in total. It is called Haploid.
Why is spindle so important to mitosis?
They pull the sister chromatids (the duplicate chromosomes of the cell) apart to opposite poles of the cell allowing new cells to form. Basically they rip the chromosomes in half so there is an equal copy of ever chromosome.
What is the farthest distance from the planet a human ever reached?
The farthest distance a human has ever reached from Earth is to the Moon, which is approximately 238,900 miles (384,400 kilometers) away. This was achieved during the Apollo missions conducted by NASA in the late 1960s and early 1970s.
Can linked genes ever be separated?
Yes, linked genes located on the same chromosome can be separated through crossing over during meiosis. This process involves the exchange of genetic material between homologous chromosomes, leading to the recombination of linked genes.
Did humans ever have a sixth toe?
Yes, some humans can be born with a sixth toe, a condition known as polydactyly. It is a genetic anomaly that can occur during fetal development. In most cases, the extra toe is usually non-functional and may be removed for medical or cosmetic reasons.
Have humans ever observed evolution happening?
Evolution is routinely observed both in nature and in the lab. Even several speciation "events" are on record.
Was the CRR5 gene ever modified in humans so they would be HIV resistant?
No! Evolution has no eye to the future!
How do you stop a Pokemon evolution in Pokemon soul silver?
To stop the evolution without using an ever-stone press ''b'' during the evolution to startle the Pokemon and leave it in it's current status
Why did Muslims first during Ramadan?

Have animals ever been on the moon?
No, animals have never been on the moon. The only living beings to have visited the moon are humans during the Apollo missions.
How many pairs of chromosomes does a human have in all their body cells?
There are 23 pairs or 46 individual chromosomes in a humans cells. 22 pairs of autosomes and 1 pair of sex chromosomes in normal humans. (There are disorders such as Turners syndrome and Klinefelter syndrome that result in different numbers of chromosomes.)
How many chromosomes in each zygote?
A zygote, regarded as the first cell of the offspring, is diploid and contains 2n number of chromosomes (the simple algebraic sum of the number of chromosomes in gamete from each parent, represented by "n"). Thus, it contains the same number of chromosomes as either of the parents (2n). For instance, a human zygote contains 46 chromosomes.
In what phase does the movement of individual chromosomes towards opposite poles occur?
At metaphase the chromosomes line up along the middle of the cell. At anaphase the chromosomes begin to move and go to opposite ends of the cell due to the action of spindle fibres. Then at telophase the chromosomes are actually at individual sides of the cell and the spindle fibres break down. So, during Anaphase.
What was the first ever sport played by humans?
The first ever sport played by humans is believed to be wrestling.
What was the first sport ever played by humans?
The first sport ever played by humans is believed to be wrestling.
What is the maximum number of chromosomes ever observed in a human individual?
Well, honey, the maximum number of chromosomes ever observed in a human individual is 92. This condition is known as triploidy, where each cell has three sets of chromosomes instead of the usual two. It's a rare occurrence, but hey, nature likes to keep us on our toes!
