Dorothy works as a medicinal chemist in a pharmaceutical company. What could one of her assignments be?
A medicinal chemist like Dorothy in a pharmaceutical company can have many tasks, but one potential assignment could be designing and synthesizing new drugs. This involves identification of potential targets, computer simulations for molecule design, lab synthesis and testing
Explanation:
As a medicinal chemist working in a pharmaceutical company, Dorothy would have a variety of tasks. One potential assignment could involve designing and synthesizing new drugs to treat specific diseases. This usually starts with research to identify potential biological targets for a drug (such as a protein involved in a disease process). Once a target has been identified, she would then conduct computer simulations to design a molecule that can interact effectively with that target. The next step would be to synthesize the drug in the lab, and then conduct tests to determine its effectiveness, safety, and side-effects.

Four locations on Earth receive sunlight at different angles. At which of the following angles will the intensity of sunlight received be the least?
90°
75°
50°
25°
The answer is 25 degree, because when the sun is directly overhead, its rays strike the earth at a 90 degree angle. The closer to 90 degrees the rays are, the more concentrated they are and the greater is the heat they produce on the earth's surface. The solar heat reach the surface of the earth becomes less intense as the angles of the rays decreases.
Answer:
D. 25

Archeologists have unearthed the tombs of thousands of workers. The author suggests that these tombs belonged to the workers who built the pyramids. What reasoning does she use to support this claim?
In addition to the tombs, archeologists have also discovered a large number of bakery sites near the Great Pyramid. In fact, there are enough bakeries to provide food for thousands of workers, which is how many it would take to construct the Great Pyramid.
Generally, how many populations can fill a niche in a particular community?
A. Only one
B. Only a few
C. Several
D. A lot
Answer: Option A; Only one
Explanation: Niche is space where the organism has a functional role. In a niche, only one species can exist, this is because if there are two species, there will be competition between them. In such a case, the species which will dominate, it will affect the survival of the other weaker one. This way, only one species will exist.
Which of these is a characteristic of index fossils? Found in the topmost rock layer Found in many layers of the same rock Have already established relative age Are limited to a particular geographic location
The index fossils have already established relative age. It is for that reason they can be used to estimate the age.
An index fossil is a fossil that spans a particular geologic time and/or given environment.
These types of fossils (index fossils) can be any type of preserved remains of an organism that lived on the Earth (e.g., an animal or plant).
For example, Ammonites are used as index fossils because they live only during the Mesozoic period (approx 245-65 mya).

Index fossils are used to determine relative age and have specific characteristics such as wide geographic distribution and rapid evolutionary change.
Explanation:An index fossil is a fossil that is used to determine the relative age of rock layers and the fossils within them. It is characterized by having a wide geographic distribution, being present for a short period of time, and undergoing rapid evolutionary change. Index fossils are found in many layers of the same rock, helping to establish relative age. They are not limited to a particular geographic location, as they can be found in different areas around the world.

What is one way that members of Archaebacteria are different from members of Eubacteria?
They lack nuclei in their cells.
They have many cells that do different tasks.
They have different types of cell walls and cell membranes.
They are single cells.
They have different types of cell walls and cell membranes.
Answer: The correct answer is-
They have different types of cell walls and cell membranes.
Archaebacteria and Eubacteria are the two distinct domains of prokaryotes ( single celled organisms that are devoid of nucleus and membrane bound organelles) according to the Carl Woese three domain system of classification.
Domain Archaebacteria consists of the primitive forms of bacteria that live under extremely harsh environmental conditions ( such as hotsprings, volcanic eruptions).
They have different biochemical composition in their cell wall.
For instance, Archaebacteria do not have peptidoglycan in their cell wall, and have ether-liked lipids ( which provides them advantage to survive under harsh conditions), which are present in the form of branched chains.
Eubacteria have peptidoglycan in their cell wall, and they have ester-linked lipids, which are present in straight chain. They live in moderate climatic conditions.

What forms of energy are being transferred during the water cycle?
A cell containing 10% sugar is placed in a 5% sugar solution.
(Feel free to sketch a diagram if you need to!)
a. How will the water move?
b. How will the cell size change?
c. Is the solution hypotonic, hypertonic, or isotonic?
When a cell containing 10% sugar is placed in a 5% sugar solution. Water will definitely migrate out of the cell through the process of osmosis. The solution is hypertonic.
What is Osmosis?Osmosis may be defined as a type of process that involves the movement of water molecules from a region of high concentration to a lower concentration of water molecules through a semi-permeable membrane.
As a result of this, the net movement of water will be out of the body and into the solution. Due to this, a cell will shrink, and after sometimes it dies through a process known as plasmolysis. The size of the cell generally reduces as compared to normal.
Therefore, when a cell containing 10% sugar is placed in a 5% sugar solution. Water will definitely migrate out of the cell through the process of osmosis.

Wind, friction, and the Coriolis effect combine to move water in which direction?
A. against the wind
B. perpendicular to the wind
C. in no particular direction
D. parallel to the wind
Wind, friction, and the Coriolis effect combine to move water in a direction that is perpendicular to the wind due to the Coriolis effect and the Earth's rotation.
Explanation:Wind, friction, and the Coriolis effect combine to move water in a specific direction. The correct answer to this question is B. Perpendicular to the wind. This is due to the Coriolis effect, which makes moving objects veer to the side because of the Earth's rotation. The combination of the wind (which pushes the water), the Coriolis effect (which turns the water to the side), and friction (which slows the water) creates a net movement of the water perpendicular to the wind's direction.
