Answer:
<h2>
Histone acetylation increase transcription.
</h2><h2>
Whereas DNA methylation decrease transcription
</h2>
Explanation:
Histone acetylation is a transcription-activating modification which occurs by the addition of acetyl group from acetyl coenzyme A, to one or more lysine residues at the ε-amino group by the enzyme histone acetyltransferases. Histone acetylation increase transcription.
DNA methylation is one of the mechanisms that cells use to control gene expression and DNA become unavailable for transcription . In DNA methylation, DNA become inactive( unavailable for transcription) so that transcription wouldn't occur.
Myth: A dead organism is the same as a nonliving thing in science.
Fact: According to science when an organism dies it not different from a non-living thing
Evidence: Non-living things are fundamentally different than living organisms mainly because of the differences in their chemical and biological structures. Living things are made of biomolecules, complex polymers like lipids, proteins, and polysaccharides based on carbon and non-living things are usually made of minerals and other inorganic compounds. So, even if an organism is dead, we can determine that it was a living thing by analyzing its chemical structure.
Myth: The Linnaeus system of classification will always stay the same.
Fact: Carl Linnaeus, a Swedish scientist from the 18th century came up with the perfect classification system that is used up to this day unchanged.
Evidence: Although this system is still widely used to classify living organisms, it has gone through some changes. Linnaeus considered kingdoms to be the utmost level of classification, but biologists today recognize a level above kingdoms, the level of domains. Some scientists also argue that classifying organisms into kingdoms should be abandoned, because not all organisms traditionally divided into kingdoms have the same origin.
Myth: Tigers and goldfish are not related.
Fact: Tiger is a top predator in the jungles of Asia and the goldfish is a small species of fish selectively bred in China and they are not at all related.
Evidence: All living things have the same way of transferring genetic information, trough the DNA molecule. Genetic analyses showed that the last common ancestor (LUCA) of all organisms on Earth has lived 3,5 billion years ago. After that, all living things diverged into separate groups. Tigers and goldfish both are animals and have a common ancestor. Tigers may be in a close relationship with other big cats like lions and cheetahs, but they all have a common ancestor with the goldfish since all vertebrates have a common ancestor that was an ancient fish species.Myth: An organism's kingdom only describes physical characteristics.
Fact: It is commonly believed that organisms are classified into kingdoms only based on their physical characteristics.
Evidence: Before the rise of molecular biology and genetics, this may have been true, but with new scientific methods and techniques, evolutionary relationships and genetic similarities are also taken into consideration when classifying an organism.
Myth: Mammals and plants don't belong in the same domain.
Fact: Mammals, being a group of animals do not belong in the same domain as plants. Evidence: All living organisms are divided into three domains: Bacteria, Archaea and Eukarya. All of the organisms that possess a eukaryotic cell, plants, animals, protists, and fungi are in the Eukarya domain. Therefore, mammals and plants belong to the same domain, the Eukarya domain.
Your myth: Humans are not animals.
Fact: Human beings are not at all related to other species and are completely different than animals.
Evidence: Although humans possess some unique features not found in other species, we are very closely related to apes, and broadly to primates, other mammals, animals, and organisms. The chimpanzee is our closest relative, and we share up to 98% of DNA sequence with them. It is estimated that our common ancestor lived around 6 million years ago.
Answer:
Option (A).
Explanation:
Limiting factors may be defined as the factors that are responsible for the limit of the population size and slows its growth. Both biotic and abiotic factors can acts as limiting factor for the population growth.
The scrub jays limits its size due to the limiting factors. The amount of food available in the area can acts as the limiting factor for the scrub jays. The limitation of food prevents the increase of scrub jays in the habitat.
Thus, the correct answer is option (a).
It is best to mix the fertilizer with the soil so it will be distributed evenly. Placing fertilizer near the root directly is dangerous as the fertilizer concentration will be too high. If the concentration of fertilizer too high, the osmotic pressure or tonicity of the solution will be high. It will attract water of nearby cell and make it shrink. The plant cell will continuously lose water, shrink and then shrivel because of this.
