Answer: The correct answer is D) One substance can be separated from another through physical means.
Mixture is a combination of two or more substances that are combined or mixed physically in a way that they do not loose their identity.
This means that mixture does not undergo any chemical change and it can be separated through physical means (like filtration). It can be of solid, liquid, or gaseous molecules.
Mixture can be primarily divided into homogenous ( having uniform composition that is every sample will have same property) and heterogenous mixture ( non uniform composition that is not every sample will have same property).
Thus, option D) is a property of every mixture.
cell membrane
B.
nucleus
C.
chloroplast
D.
chromosome
The climate of neighbouring lands can be influenced by mountains. Mountains can prevent rain in some places, resulting in rain on one side and a desert on the other.
Thus, Mountains can alter an area's weather or climate, affecting the temperature and moisture, for instance. The mountain website to learn everything there is to know about mountains and how they are created.
The farther up a mountain you climb, the colder it gets. So, compared to the flat ground around them, mountains typically have wetter climates. The weather in the mountains also varies greatly. For instance, there can be clear, blue skies one minute, then a thunderstorm the next.

Answer:
C. 5 km/h north
Explanation:
Speed is the rate at which an object changes position, and it is measured in meters per square seconds. The formula or equation used in calculating speed is distance divided by time. The distance traveled is always in meters and time is always in seconds to get the speed it will be one meter per second. Speed doesn’t specify the direction at which an object will travel. Hence the answer is C. 5Km/hr north
B. iron
C. lithium
D. zinc
Answer: C. lithium
Explanation:
Standard reduction potential is the tendency for an element to gain electrons or get reduced ,measured at standard conditions i.e. when concentration is 1 M and temperature is 298 K.
It is given by:
Thus lithium has the lowest tendency to accept electrons and thus has lowest standard reduction potential.
B. because a memoir relates only the experiences of others
C. because a memoir relies largely on the writer's memories
D. because a memoir is not written by a historian
Answer:
Option C.
Explanation:
