The tongue is an example of an organ that assists in the process of digestion. which of the following best describes the level of structural organization for organs like the tongue?
A. It is less complex than a tissue
B. It is more complex than an organ system
C. It is less complex than a cell
D. It is more complex than a tissue
Answer:
C
Explanation:
The level of structural organization for the tongue is that it is more complex than a tissue. So the correct option is D.
What is a tongue?
In most vertebrates, the tongue is a muscular organ on the floor of the mouth that may move in a variety of ways. It is extended and specialised in grabbing insect prey in some animals (like frogs).
While cats and certain other animals use their tongues as tools for grooming and cleaning, some reptiles' tongues serve largely as sensory organs.
The tongue is an essential auxiliary organ in chewing and swallowing, helps mammals create negative pressure in the oral canal to permit sucking, is a key carrier of taste receptors, and helps humans speak.
The mammalian tongue is formed of a complex of striated, intertwined muscles, fat, and glands, all coated in mucosal surfaces. Humans often have their front tongue ends and margins in contact with their teeth, which facilitates communication and swallowing.
Therefore the correct option is D.

Some transcription signals are located thousands of base pairs upstream of the gene they regulate. How does the distant signal initiate transcription
Answer:
enhancer sequences bind to transcription factors to increase the likelihood of transcription
Explanation:
Enhancers are short DNA regions (50–1000 bp) that may be localized upstream and downstream from the transcription start sites of the gene. It has been shown that enhancers can be localized several kilobases (30-100 kb) either 5' or 3' of the gene. These sequences bind to proteins (generally transcription factors) in order to alter the 3D structure of the DNA, thereby increasing the likelihood of transcription.

If the lionfish population keeps rising, what would be the possible effect on the trophic levels of
the ecosystem?
Answer:
As lionfish populations grow, they put additional stress on coral reefs. For example, lionfish eat herbivores, and herbivores eat algae from coral reefs. Without herbivores, algal growth goes unchecked, which can be detrimental to the health of coral reefs.
Explanation:
The lionfish are eating other consumers, so the native consumer populations are dwindling. This decrease can have a ripple effect. Larger predatory animals may not have enough food to eat because the native species are decreasing.

O Since menopause, Sarah's levels of the hormone estrogen have dropped.
Answer: Since menopause, Sarah's levels of the hormone estrogen have dropped.
Explanation:
The most likely cause of injury in the following scenario is that because of the menopause, Sarah's levels of the hormone estrogen, which is also known as a female hormone, have dropped and because of that she is playing ice hockey with others and since she did not play it before, she broke her elbow.
She broke it because she was inexperienced with it and if she has played it before menopause she could not break it.

what are the scientist doing incorrectly? what could they do to make their work in the lab safer? why is it important to follow these procedures? part c
Answer:
What the scientist is doing incorrectly is placing test tubes in a cabinet in disorderly form, without protective or biosafety equipment, having other tubes loose on the shelf, which can fall, break and spill their contents.
Explanation:
The image scientist is doing an incorrect procedure because
He is handling laboratory material without protection. He has messy tubes on the shelf of the cabinet, which can be chewed and broken, spilling their contents. He is not using a ladder to reach the highest spaces in the cabinet and place the tubes.What could they do to make their work in the lab safer?Use biosafety equipment to handle containers with chemical or biological substances.Keep the tubes in racks or tube holders to prevent them from falling accidentally.Place the tubes in an orderly manner, using a ladder to place the tubes at the top of the cabinet.Why is it important to follow these procedures?It is important to follow these procedures to protect his body from accidental spills, as well as to avoid breaking containers and contaminating the work space.
