Answer:
Purple, spherical-shaped organisms arranged in chain like formations.
Explanation:
Bacteria are the microscopic organisms and included in the prokaryotes as they do not have nucleus. Two main types of bacteria are gram positive bacteria and gram negative bacteria.
The gram positive bacteria has thick cell wall peptidoglycan cell layer and can uptake the crystal voilet stain. These bacteria seems purple under the microscope due to the uptake of stain. The bacteria Streptococcus pyogenes are spherical in shape and occurs in the cluster of chain.
Thus, the correct answer is option (d).
Can you give me the options?
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.
The reason why it is much easier to read while shaking your
head rather than reading and shaking the page is because of the vestibular
ocular reflex, it is because when reading and shaking your head the vestibular
ocular reflex were able to respond faster than prolong and slow movements.
Answer:
Runners
Explanation:
stems are usually upright and prop up the plant to gather sunlight, however, some stems grow along the ground. These stems are called runners and the plant itself is called a stolon. Runners are involved in asexual reproduction of plants. They have nodes along them which can grow into another plant.
