Starting with a fertilized egg (zygote), a series of six cell divisions would produce an early embryo with 64 cells.
<h3>What about zygote?</h3>
- A zygote is a eukaryotic cell created when two gametes fertilize one another.
- The genome of the zygote, which is made up of the DNA from each gamete, has all of the genetic material for a brand-new unique organism.
- The zygote represents the earliest developmental stage of multicellular organisms.
- Zygote, the fertilized egg cell produced when a female gamete (egg, or ovum) and a male gamete combine (sperm).
- The zygote stage is brief in the embryonic development of humans and other animals, and it is followed by cleavage, in which the single cell divides into several cells.
- When male and female gametes combine to produce an embryo, the first diploid cell that results is known as a zygote.
- The first week after conception is when the zygote stage develops.
- Zygote is the name given to the sperm and egg together.
- All of the DNA required to develop into a baby is present in the zygote.
- The mother's egg and the father's sperm each contribute 50 percent of the DNA.
- The following several days are spent by the zygote moving down the fallopian tube.

Answer:
they are invasive species
Explanation:
Invasive species can be defined as a category of non-indigenous species that may cause environmental harm. Invasive species have a high fecundity rate, an important dispersal capacity, highly plastic phenotypes, general habitat preferences, ability to circumvent biological controls (i.e., competitors, predators, diseases), etc. In consequence, these features become invasive species practically impossible to eliminate after introduction into a certain area and highly adaptable to new environmental conditions.
Vehicle exhaust fumes are also a threat to our air supply of clean air. It is means of transportation for a majority of the population whether it is a personal car or a ride on public transportation. It produces carbon dioxide and other greenhouse gases that keep heat trapped in the earth’s atmosphere.
The right option is; A. Compounds can be separated by physical methods.
Compounds can be separated by physical methods is the statement about compounds that is false.
A compound is a molecule that is formed from the combination of two or more different chemical elements. The atoms of the different elements that form a compound are held together by chemical bonds (covalent and ionic) that are not easy to break. The component of a compound can only be separated by chemical means and not by physical methods. An example of a compound is water (H2O) which is composed of hydrogen (H) and oxygen (O) atoms.
The answer to this question would be: paranasal sinus.
There are a few sinuses near the face area. The sinus can be classified based on the bone that makes then to sinus maxillae, ethmoid, sphenoid and frontalis. This structure frequently gets infected causing sinusitis. Sinusitis patient can complain pain or feel the sinus got filled with some liquid.
