Biology
1 answer:
Dimas [21]2 years ago
5 0

Answer:

B. The periplasmic space contains the peptidoglycan layer of Gram-negative bacteria.

Explanation:

Periplasma is the compartment that surrounds the cytoplasm in Gram negative bacteria. It is comprised between the plasma membrane (which is inward) and the outer membrane of the gram negative, on the outside.

This periplasmic space contains the peptidoglycan layer and proteins that are responsible for receiving extracellular signals, among other functions.

The high concentration of peptidoglycan causes this space to be in a gel-like state.

Write function of snakes hard scales
Goryan [66]

Answer:

The answer to this question is given below in this explanation section.

Explanation:

                  "function of snakes"

Snakes are elongated,legless,carnivorous reptile of the suborder serpents.Like all other squamates,snakes are exothermic,amniotic vertebrates covered in over applying scales.Many species of snakes have skulls with several more joints than their lizard ancestors,enabling them to swallow prey much larger  than their heads with their highly mobile jaws.To accommodate their narrow bodies,snakes,oared organ appear one in front of other instead of side by side,and most have only one functional lungs.Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.Legless lizard have eyelid and external ear.

A scale protect the body of the snakes,aids it in locomotion,allows moisture to be retained within,alters the surface characteristics such as roughness to aid in camouflage,and in prey capture (such as Acrochordus).

Snake scale originates from the epidermis.The integument of the snakes in covered with two primary scale type,both originating from the epidermis.Small scale over the dorsum and lateral surface of the snake.Whereas larger scales cover the vent rum.

Create some predictions to support the sunflowers in the future?
Oksi-84 [34.3K]

Answer:

The humble sunflower appears not quite of this earth. Its yellow crowned head sits atop its stalk like a green broomstick. Its seeds, arranged in a logarithmic spiral, are produced by tiny flowers called disc florets that emerge from the center of its head and radiate outward. But aside from being a biological marvel, the sunflower is also often in the scientific spotlight.

From understanding how new plant species emerge to studying “solar tracking,” which is how the flowers align themselves with the sun’s position in the sky, sunflowers are a darling in the field of science. However, researchers can only get so far in understanding a plant without detailed genetic knowledge. And after close to a decade, it has finally unfurled itself.An international consortium of 59 researchers who set their sights on the laborious task of sequencing and assembling the sunflower’s genome published their results in a 2017 study in Nature. This achievement will provide a genetic basis for understanding how the sunflower responds and adapts to different environments. “We are on the cusp of understanding sunflower adaptability,” says Loren Rieseberg, a leading sunflower expert at the University of British Columbia and a supervisor of this study.

With its genome assembled, scientists are hopeful for the next phase of the sunflower’s scientific career: as a “model crop” for studying climate adaptability in plants. This task is more complex and urgent now than ever. Climate change, according to a paper in the Annals of Botany, “will influence all aspects of plant biology over the coming decades,” posing a threat to crops and wild plants alike.
