What is the most social animal?
I believe that elephant would have to be the answer. Baby elephants raised by humans need to have a different caretaker sleep with them each night. If one is with them for more than that, when that person isn't there, the elephant will literally die of loneliness. Ask yourself if that would happen to a human, or a dog, or a hominid. Every time I see a baby elephant playing it brings a tear to my eye that such a sensitive creature can be so alive. It restores my faith that the universe is not such a bad place.
What are some important discoveries in botany?
Three important plant experimentation discoveries by scientists within the last 300 years are: Nicholas de Saussure was the first chemist to begin quantifying the process of photosynthesis. Jan Baptista's experiments showed that the loss of soil mass < gain of plant mass and that the gain of plant mass is related to water. Ingenhousz found that air would be purified only when the sun's energy and green plants worked together in the system.
How do you polish a Breyer Model horse?
You should not attempt to polish a Breyer model horse. The paint used is fairly durable, but cannot withstand most solvents. A Glossy model horse is glossed at the factory. Matte finish horses have no top gloss coat. A dirty model should be gently washed in warm soapy water, using a mild dish detergent. Black marks may not be able to be removed without damaging the underlying paint.Adding any kind of additional gloss to a model can actually detract from the value, so consult a model horse collector or one who restores models before actually attempting to alter a model in the clean-up process.
How do you help a wild baby bunny?
If your rabbit is dying and you don't know why, bring it immediately to a vet who has experience and knowledge in treating rabbits. Even if the rabbit has died, the vet can figure out what happened. You can also find help from people on online rabbit forums. See the related questions below for more information and helpful links.
What process union of egg and sperm restores chromosome number?
The union of an egg and sperm restores the chromosome number through the process of fertilization. During fertilization, the haploid egg and haploid sperm fuse to form a diploid zygote, which contains the full complement of chromosomes (46 in humans). This restores the normal chromosome number in the resulting offspring.
After gametogenesis takes place which process restores the diploid chromosome number of the species for the next generation?
In the S phase before mitosis, the chromosomes duplicate into sister chromatids before spearating during mitosis. The number of chromosomes remainds diploid because they double before they are halved.
How does meiosis prevent the number of chromosomes from doubling every generation what two cells join during fertilization?
Meiosis is a cell division process that reduces the chromosome number by half, ensuring that the number of chromosomes remains constant across generations. During fertilization, a sperm cell from the father and an egg cell from the mother join to form a zygote, which restores the full chromosome number for the next generation.
How does fertilization affect the chromosome number of a zygote?
Sperm contains 23 chromosomes. An egg contains 23 chromosomes. The zygote (a fertilized egg) contains 46 chromosomes. Yet, it is also important to consider that the egg completes meiosis before joining with the sperm, thereby shedding half of its 46 chromosomes into a polar body that adjoins the zona pelucida lining.
What process restores the 2N chromosome number in a zygote's somatic cells for growth and development to continue?
The process that restores the 2N chromosome number in a zygote's somatic cells is called mitosis. During mitosis, the replicated chromosomes are divided equally between two daughter cells, ensuring that each cell receives a full set of chromosomes. This allows for growth and development to continue with the correct number of chromosomes in each cell.
How does fertilization relate to diploid cells?
Fertilization is the process where two haploid gametes (sperm and egg) fuse to form a diploid zygote. This zygote then develops into a new organism with a full set of chromosomes, thus relating fertilization to the formation of diploid cells.
Does fertilization reestablish the diploid state of a species?
Yes, fertilization combines the haploid gametes (sperm and egg) to form a diploid zygote. This process restores the diploid state and ensures that the resulting organism has the full set of chromosomes characteristic of its species.
If the original cell that divides by meiosis diploid or haploid?
The original cell that undergoes meiosis is diploid, meaning it contains two sets of chromosomes. This diploid cell, typically a germ cell, divides through meiosis to produce haploid gametes, which have only one set of chromosomes. This reduction in chromosome number is crucial for sexual reproduction, ensuring that when gametes fuse during fertilization, the resulting zygote restores the diploid state.
Describe some of the pieces of information that scientists discovered that contributed to the chromosome theory of inheritance?
Scientists discovered that chromosomes are inherited in a predictable manner during cell division, they observed that the number of chromosomes in a species is constant, and that specific traits are linked to particular chromosomes. They also found evidence of chromosomes segregating independently during meiosis.
What do gametes form in?
Gametes form in specialized reproductive organs; in animals, they are produced in the gonads—testes for sperm and ovaries for eggs. In plants, gametes are formed in structures like anthers (for pollen) and ovules. These cells undergo meiosis to reduce their chromosome number by half, ensuring that when fertilization occurs, the resulting zygote restores the full chromosome count.
How does the chromosome number of a muscle cell compare to that of an egg cell from the same animal?
A sperm cell is the male sex cell. As such it only carries 1/2 of the number of chromosomes of a regular cell. This is because it fuses with the female sex cell to form a complete set of chromosomes. Essentially, where the number of chromosomes in the muscle cell is 2n, the sperm cell only has n chromosomes.
Why reductional division or meiosis essential in organism?
Meiosis reduces number of chromosomes to one half . when two gametes fuse , it restores original diploid number of chromosomes .With out this diploid number of chromosomes could not be maintained .
