Explanation:
Chewing, grinding, pressing, salivating
When we chew, the tongue and the cheeks work together to constantly move the food between the teeth so that it can be chewed. The tongue presses the crushed food against the palate and moves this bolus, which is then ready to be swallowed, to the throat.

Explain why variation is an advantage for a species such as the common emerald dove
Explanation:
Having variation within a species means that if the environment changes there may be individuals within the species more able to withstand the change and survive.
Variation refers to the differences between members of the same species. There is usually extensive genetic variation within a population of organisms or a species.
The common emerald dove (Chalcophaps indica), also called asian emerald dove and grey-capped emerald dove, is a widespread resident breeding pigeon native to the tropical and subtropical parts of the Indian Subcontinent and Southeast Asia, the dove is also known by the names of green dove and green-winged pigeon. The common emerald dove is the state bird of the Indian state of Tamil Nadu. The Pacific emerald dove and Stephan's emerald dove were both considered conspecific.
You are building a birdhouse when you cut your finger. Predict which body systems would be immediately involved with your
reaction to the cut.
Answer:
A.
Explanation:
These systems will be involved!
Hope this helps, have a great day.
The nervous system, circulatory system, and integumentary system are body systems involved immediately when you cut a finger.
The integumentary system is the system that groups the natural covering of an organism, for example:
SkinBarkShellThe nervous system is in charge of electrical signals. These signals are those produced by the senses such as taste, smell, sight. Also, they are responsible for sending signals of pain, satisfaction, pleasure, and others to the brain.
The circulatory system is the system in which blood is transported throughout the body for oxygenating and energizing the entire body.
When someone cuts themselves they feel pain (nervous system), blood comes out (circulatory system) and their skin opens and some of its lower layers (integumentary system) can be seen. Therefore, the correct answer is A.

Mr. Doe wanted to perform an experiment to determine if doing a class review before a test would increase test scores. Mr. Doe normally does not review. To perform this experiment, Mr. Doe reviewed material with 2nd period before a test and did not review with 3rd period. After grading papers, he found that 2nd period had an average grade of 93 and 3rd period had an average grade of 72. He determined that reviewing before a test might increase test scores. 2. Which of the following is the control group?
Answer:
3rd Period
Explanation:
2nd period reviewed material with Mr. Doe
3rd period did NOT reviewed material with Mr. Doe
Experimental group is the group being affected.
Control group is the group not being affected.

Which element has four valence electrons?
(1 point)
O beryllium (Be)
O potassium (K)
O sulfur (S)
O silicon (Si)
Answer:
O silicon (Si)
Explanation:
-Valence electrons are electrons of the outermost shell which can participate in chemical bonding. ... -As in silicon, four electrons are present in the outermost shell, so silicon has Four valence electrons.
Among the options given in the question, the element that has four valence electrons is known as Silicon. Thus, the correct option for this question is D.
What are Valence electrons?Valence electrons may be defined as the number of electrons that are present in the outermost shell of an element. These electrons actively take part in chemical bonding due to the sharing and pairing of electrons.
The atomic number of beryllium is 4, it has valance electrons of two. Potassium has an atomic number of 19, it has a valence electron of one. Sulfur possesses an atomic number of 16, it has valence electrons of six. While Silicon has an atomic number of 14, its electronic configuration is 2, 8, and 4. So, it has valence electrons of four.
Therefore, the element that has four valence electrons is known as Silicon. Thus, the correct option for this question is D.

You work in a lab that studies brains and behavior. You and your labmate have both submitted rodent brains to a colleague to be sectioned. Your species is a squirrel that is known for storing large numbers of nuts each autumn in a variety of hidden locations. Your labmate's species is a mole with almost nonexistent eyes. How do you predict their brains will compare
The squirrel had a larger brain and is smarter. I say this because the squirrel has to be smart enough to gain a large amount of nuts, hide those nuts from others, and remember where those nuts are. On the other hand, the mole is less smart bc it is primarily underground. The mole's location underground helps to keep it safe from other predators so it doesn't have to worry too much about that. the mole also can't see which means that sight isn't of enough importance to keep.
Okazaki fragments are best described as:
A. short segments of DNA formed on the leading strand.
B. cause by the DNA Helicase building in the 3 to 5' direction.
C. short segments of replicated DNA formed on the lagging strand.
O
D. caused by the single strand binding proteins moving in away from the replication fork.
DNA replication occurs only in 5'-3'. Option C. Okazaki fragments are best described as short segments of replicated DNA formed on the lagging strand.
What is an Okazaki fragment?During DNA replication, the molecule unwinds and the two strands get separated.
Different enzymes and proteins are involved in the replication fork formation, such as helicase (enzyme needed to break hydrogen bonds and separate the two original strands) and topoisomerase (enzyme that releases tension).
DNA polymerase makes the new nucleotides enter the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs thymine, and cytosine pairs guanine.
Since DNA strands are antiparallel and replication occurs only in 5'-3' direction, one of the strands will replicate continuously, while the other strain will be replicated by short fragments known as Okazaki fragments.
Okazaki fragments are only formed on the lagging strand.
According to this framework, the correct option is C. short segments of replicated DNA formed on the lagging strand.
