Answer:
The correct answer is- Histone
Explanation:
DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.
Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.
DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.
Phagocytosis is the process by which immune cells engulf and then destroy bacteria
This was answered else where on Brainly, and this is what they said,
"Most proteins in the living organisms are enzymes and they required specific optimum conditions in order to function optimally. Disruption in the homeostasis will leads to deactivation of these proteins. For instance, if the temperature needed for a protein to work optimally has been exceeded, the protein may be denatured and will be unable to perform its needed functions, this may result in several adverse effects in the organism."
the answer is b) shoppers no longer need to leave the house or spend hours at the mall to make a purchase
Answer:
The correct answer is option A) "+/+".
Explanation:
Cellulose-digesting organisms in the gut of a termite and the termite itself have a positive interaction among them. The interaction among these organisms is classified as a symbiotic interaction because both organisms are benefited from it. Cellulose-digesting organisms in the gut of a termite obtain food and protection from the termite, and in return the termite is able to digest the cellulose of wood, its main source of food.
