The correct answer is investigation
Explanation:
Investigation here means scientific investigation or experiment. In scientific process, when a new phenomenon is observed, an hypothesis is made in an attempt to explain the concept behind the observation. An experiment/investigation is then embarked upon to determine if the hypothesis provides the right answer or perspective to this observation. The outcome/conclusion of this experiment after repeated trials is referred to as theory while a theory tested over a long period of time is a law.
However, if the experiment doesn't confirm the hypothesis, new questions or hypothesis will have to be proffered

A. currents to the left-counterclockwise-regardless of location
B. currents to bend to the left-counterclockwise-in the northern hemisphere
C. currents to bend to the right-clockwise-regardless of location
D. currents to bend to the right-clockwise- in the northern hemisphere
Answers
Answer:
It's D
Explanation:
The reason for this is because the Coriolis effect causes currents and cyclonic weather weather systems to bend to the right in the northern hemisphere and left in the southern hemisphere.
*If it includes clockwise and counterclockwise, I believe northern hemisphere is clockwise and southern hemisphere is counterclockwise.
The Coriolis effect causes currents to bend to the right-clockwise- in the northern hemisphere.
An object, when moving on any rotating system undergoes an additional acceleration produced by a "force" perpendicular to the movement.
The result that this "force-acceleration" causes to the object is a deviation of its path that gives rise to a curved path, this "force" is the Coriolis effect.
The rotation of the Earth has an effect on objects that move on its surface called the "Coriolis Effect."When an object starts a movement pointing in a direction in the Northern Hemisphere, whatever that direction, the actual trajectory is curved to the right with respect to the initial direction.In the Southern Hemisphere it produces deviations to the left of the movements.Therefore, we can conclude that the Coriolis effect deflects ocean currents to the right in the northern hemisphere, and to the left in the southern hemisphere.

2. Calcium (2 electrons)
3. Oxygen (6 electrons)
4. Lithium (1 electron)
5. Xenon (8 electrons)
Answers
Answer:
1. Fluorine (7 electrons) => c. steals 1 electron
2. Calcium (2 electrons) => a. gives away 2 electrons
3. Oxygen (6 electrons) => d. steals 2 electrons
4. Lithium (1 electron) => e. gives away 1 electron
5. Xenon (8 electrons) => b. neither gives away nor steals any electron
Explanation:
Given the following valence electrons of the atoms listed above, each atom can be matched to its corresponding number of electrons it can steal or give away as they form bonds and attain a stable state:
1. Fluorine (7 electrons) => this will steal 1 electron from another atom to attain a stable state when it comes to make the number of electrons 8.
2. Calcium with 2 valence electrons, will give away this 2 electrons in its outer shell to be stable and form bond with another atom that will accept these 2 electrons.
3. Oxygen with 2 valence electrons, will steal 2 electrons to make the electrons in its outer shell 8, as it bonds with another atom to become stable.
4. Lithium will give away 1 electron to become stable when it combines.
5. Xenon with 8 electrons in its outer shell is in a stable state and kind of inert. It doesn't need to receive or steal any electron from or to any other atom in this state.

The cytoskeleton of a eukaryotic cell plays a major role in organizing the structures and activities of the cell. The cytoskeleton consists of three main types of fibers: microfilaments, intermediate filaments, and microtubules. The three types of fiber differ in size, composition, and the functions they perform in the cell. A structure of the cytoskeleton including microfilaments, intermediate filaments, and microtubules. Intermediate filaments are the thinnest ones, and microtubules are the widest ones. Drag the terms on the left to the appropriate blanks in the sentences on the right. Terms can be used once, more than once, or not at all.
1. In eukaryotic flagella, the fibers that slide past one another due to the activity of dynein proteins are _______.
2. Many cell organelles, most notably the nucleus, are anchored by which are assembled from a diverse class of proteins.
3. Centrosomes are sites where protein dimers assemble into ________.

Answers
Answer:
1. Microtubules
2. Intermediate filaments
3. Microtubules
4. Microfilaments
5. Intermediate filaments
6. Microfilaments
Explanation:
According to this question, the three main types of fibres found in the cytoskeleton of eukaryotic cells are microfilaments, intermediate filaments, and microtubules. They serve different functions in the cell.
1. MICROTUBULES are proteinous fibres found in cells. They are responsible for the functionality of the eukaryotic flagella as they slide past one another due to the activity of dynein proteins.
2. INTERMEDIATE FILAMENTS are one of the three types of cytoskeletal fibres found in eukaryotes. They are made of different proteins and provide structural support/anchorage to many cell organelles, most notably the nucleus.
3. Centrosomes are organelles found in cells responsible for organizing proteinous fibres called MICROTUBULES. Hence, they are are sites where protein dimers assemble into microtubules.
4. Microfilaments are narrow cytoskeletal fibres made of protein called ACTIN. MICROFILAMENTS are actively involved in locomotion or movement, hence, their regulated assembly and destruction is responsible for the extension of pseudopodia in amoeba.
5. As mentioned earlier, INTERMEDIATE FILAMENTS are one of the three cytoskeletal fibres but the only one not involved in intracellular movement or locomotion. They are rather supportive fibers.
6. Muscle contractions is as a result of the activities of ACTIN AND MYOSIN proteins, which are components of a type of cytoskeletal fibre called microfilaments. Therefore, myosin motor proteins move across tracks of MICROFILAMENTS during muscle contraction.

Answers
Answer:
Enzymes are produced through protein synthesis within cells. Once formed, the location of enzymes secreted varies. Enzymes may remain within the cell. An example of an enzyme that does this is DNA polymerase that helps to form new DNA. Enzymes may also become embedded in the plasma membrane. The enzyme lactase does this. It can be found in the plasma membranes of small intestine cells. As a final option, some enzymes will be secreted from the cell and used by other cells. An example of this can be seen with pancreatic production of pancreatic amylase. Once it is released from the pancreas, it participates in starch digestion in the small intestine.
Explanation:
Enzymes are a special type of protein that have the important function to catalyze chemical reactions - this means that the lack of a certain enzyme will result in an important chemical reaction not happening, or happening at a much lower rate. These chemical reactions can be anabolic (meaning the creation -synthesis- of a molecule) or catabolic (which refers to the destruction -degradation- of a molecule).
For example, like the paragraph above explained, enzymes in the digestive tract have the task to convert the food that we ingest into smaller particles that can be absorbed by our intestines and used as nutrients. If one of these enzymes were to be absent, that specific nutrient wouldn't be properly digested - as it happens in people that are lactose intolerant (they lack the enzyme lactase, so they can't digest lactose, the sugar present in dairy products).
