The freezing point of a 1 m solution of f e c l 3 is expected to be choose. That of a 1 m solution of glucose. This is because f e c l 3 choose. And choose. Compared with glucose
1m solution of f e c l 3 has a lower freezing point compared to 1 m solution of glucose.
What is freezing point?The term freezing point refers to the point at which liquid converts to solid. We must note that the freezing point iof a substance is a colligative property hence it depends on the amount of substnace present.
Having said this, we know that 1m solution of f e c l 3 contains more particles than 1 m solution of glucose hence 1m solution of f e c l 3 has a lower freezing point compared to 1 m solution of glucose.

The freezing point of 1M FeCl3 is found to be lower compared to the freezing point of 1M Glucose.
What do you mean by Freezing point?A Freezing point may be defined as the temperature at which a liquid turns into a solid when cooled.
1M FeCl3 solution is able to dissociate into cations and anions in an aqueous solution and thus will have more solute particles as compared to 1M Glucose.
Therefore, the freezing point of 1M FeCl3 is found to be lower compared to the freezing point of 1M Glucose.

Naomi runs a computer simulation for a population of mice in a meadow ecosystem. The simulation begins with 100 mice, divided equally among brown and white variants. The variants are similar apart from their body color. A mating of a white and brown mouse may produce a speckled mouse, which is mostly brown with some white markings. The table shows the numbers of each mouse variant over 7 reproduction cycles. Only adult mice are reported in the table.
Which of these events did the computer MOST LIKELY include in its simulation?
A. After cycle 2, a disease arrived that affected white mice only.
B. After cycle 2, a predator arrived that saw white mice more easily than brown mice.
C. After cycle 4, brown mice and white mice began living separately, and stopped interbreeding.
D. After cycle 4, a predator arrived that saw white mice more easily than brown mice.
E. After cycle 4, a disease arrived that affected brown mice only.
After cycle 4, a disease arrived that affected brown mice only was most likely included in its simulation.
What is Disease?This is defined as any harmful deviation from the normal structural or functional state of an organism.
This usually leads to death and the table shows a steady decline from cycle 4 which means a disease most likely arrived which affected brown mice only.

Pioneer species move into an area after a disturbance that forms new land without soil.
Pioneer species are the first organisms to inhabit a region that has experienced a primary succession.
How do pioneer species arrive?
Primary succession begins in barren areas, such as on bare rock uncovered by a retreating glacier.
The first residents are lichens or plants that can survive in such an environment. Over hundreds of years these “pioneer species” transform the rock into soil that can support simple plants such as grasses.
Thus, Pioneer species move into an area after a disturbance that forms new land without soil.

What type of muscle assists an agonist by causing a like movement or by stabilizing a joint over which an agonist acts?.
Answer:
The correct answer is a synergist.
Explanation:
The muscles that provide movement in the musculoskeletal system act in groups or pairs, such as the hamstrings and quadriceps, or the biceps and triceps. An agonist, often known as a primary mover, is a muscle that works.
Synergists are muscles that assist the prime mover by moving in the same direction and at the same time. Synergists provide a motion similar to that of the prime mover while also stabilizing the joints that hold the agonist in place for smooth movement.
As a result, the correct response is synergist.
