Quasar is a star like object that is very bright and distant.
Quasars are massive, bright, and most distant known celestial objects that release high amounts of energy in the form of electromagnetic radiation, which usually has a star-like image in a telescope. Quasars can only be found in galaxies that have super-massive black holes (black holes that have billions of times of solar masses). In quasars, the black holes are enclosed by a gaseous accretion disk.
Hello!
Natural selection is the way that animals evolve.
The theory of natural selection is that the animals that do not have a specific trait to survive in their environment will die. The animals that do have the trait will survive. The animals that survive will then pass the trait down to their offspring, who will also likely survive because they have the trait. This is how species evolve and continue to survive in their environment.
The species evolve because only the fittest survive (this is known as "survival of the fittest"). The animals that do not have the needed traits will die and they cannot have offspring.
I hope this helps answer your question! Have a great day!
Answer:
The slime molds are important to ecosystems because they act as decomposers which will release nutrients back into the environment. Earth basically depends on protists because they supply oxygen and are critical in the food chain.
The chart here is not found but is possible to determine phenotypes and genotypes by calculating the gametic combinations through a Punnet square.
<h3>What is a Punnet square?</h3>
A Punnet square is a specific diagram used in genetics to calculate phenotypic and genotype frequencies.
A Punnet square is constructed by using the possible gamete combinations that will give rise to offspring.
The phenotypic frequencies obtained from a Punnet square depend on the type of inheritance mechanism.

Explanation:
Hemoglobin, or haemoglobin, abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of almost all vertebrates as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the lungs or gills to the rest of the body.
