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.

Explanation:
The plant has the largest vacuole than animal cells. The cytoplasm is mostly composed of water, salts, and proteins. It is one out of 2 types of endoplasmic reticulum, characterized by the appearance of the ribosomes that give it a grainy appearance. The cell membrane is made of millions of smaller molecules that create a flexible and permeable container.

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

2nd period reviewed material with Mr. Doe
3rd period did NOT reviewed material with Mr. Doe
Experimental group is the group being affected.

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 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.
Which of the following phrases best describes a solvent?
A) can be dissolved by the solute
B) has a high concentration of solutes
C) usually a sugar or protein
D) present in a greater concentration that solutes
A solvent is a substance present in a greater concentration than solutes (Option D).
A solvent is a substance (usually a liquid) that dissolves another substance/s in order to form a solution.The solvent has the ability to dissolve other substances present in the solution that are referred to as solutes.Some of the most common solvents include water, ethanol and methanol.In conclusion, a solvent is a substance present in a greater concentration than solutes (Option D is correct).

About how many times thicker is a
cell wall compared to a cell
membrane?
A. about twice as thick
B. about five times as thick
C. about half as thick
D. up to 100 times thicker
Explanation:
I think it's up to 100 times
A barrier enclosing the cell, the cell wall is located outside the plasma membrane. The plasma membrane can be up to 100 times thinner than a cell wall, hence option D is correct.
What is a cell wall?Cellulose, a polysaccharide sugar that gives the cell wall strength, makes up the majority of its composition.
The leaf blades of L. perenne and T. repens and the stems of Z had the thinnest cell walls (0–9 m) and the thickest (2–0–3 m) among the cells classified as thick-walled.
Compared to gram-negative cells, gram-positive cells have substantially thicker cell walls. The typical thickness of the gram-positive cell wall is 20–80 nm, whereas the typical thickness of the gram-negative cell wall is 5–10 nm.
Therefore, the cell wall is up to 100 times thicker compared to a cell
membrane, hence option D is correct.

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.
