Answer:
Because older cultures of gram-positive bacteria tend to lose their ability to retain crystal-violet in the peptidoglycan of their cell walls and can be confused with gram-negative bacteria.
Explanation:
Gram staining is used to differentiate between two major groups of bacteria. Gram-positive and gram-negative, these bacteria differ in the amount of peptidoglycan in their cell walls. Gram-positive bacteria have a higher amount of peptidoglycan, which absorbs the violet crystal complex used in gram staining, staining them purple/violet. Old cultures of gram-positive bacteria tend to lose the ability to retain the violet crystal and are stained by safranine, staining them red/pink and appear to be gram-negative.
Answer:the decline of lichens is an important indicator of an imbalance in the ecosystem. this research can help system ecologists predict how pollution will affect the entire ecosystem
Explanation:
I think the answer is evolution.
NO, they should not.
Erythrocytes, leucocytes, and proteins (albumin)
are not small enough to pass through the capillaries of the
glomerulus unless there is damage to the glomerulus. However, glucose does pass through into the glomerular filtrate. Nonetheless, glucose is fully reabsorbed back in the proximal
convoluted tubule (unless you have severe diabetes).
The new technology allows detection of a structure that could not be detected previously. Thus, the correct option is D.
<h3>
What are the benefits of technology?</h3>
Sales will probably improve as a result of technology that makes it simpler for people to buy from you, including an e-commerce solution and numerous payment apps. Marketing departments are forced to adapt the social media platforms that your clients and potential customers use since they are born and die on a monthly basis.
The tasks that HR departments perform for hiring, reviewing applicants, onboarding, and training involve a significant amount of technology. The more HR duties you can complete using technology, the quicker they can be completed and the less likely it is that you will make a mistake that could result in a lost recruit, an employee leaving, or a lawsuit. Employee education on topics like benefit enrollment and corporate policies, for instance, guarantees appropriate paperwork is done and cuts down on training time for new hires.
