When a subject is made up of nouns joined by or, the verb agrees with the last noun. She or I run every day. Collective nouns (team, couple, staff, etc.) take a singular verb.

A pyramid of numbers shows the total number of individual organisms at each level in the food chain of an ecosystem. An inverted pyramid of numbers can be found in an ecosystem where the community contains a few producers with a very large biomass that support a larger number of smaller consumers. In this, the energy is maximum at producer level, followed by primary consumer level (herbivores), followed by secondary consumer level (carnivores). The base of the pyramid of number represents the producers in a grassland ecosystem. Thus, the correct answer is 'Always upright.

A natural ecosystem is the result of interactions between organisms and the environment. For example,
an ocean is classified as a marine ecosystem, which consists of algae, consumers and decomposers. A
cycle occurs in this type of ecosystem that begins with algae converting energy via photosynthesis. After
consumers feed on the algae, energy is transferred between the organisms. Once consumers die in this
system, decomposers turn them into organic matter. This process occurs naturally over a period of time,
whereas in an artificial ecosystem, human intervention is required.
An artificial ecosystem is not self-sustaining, and the ecosystem would perish without human assistance.
For example, a farm is an artificial ecosystem that consists of plants and species outside their natural
habitat. Without humans, this ecosystem could not sustain itself. The plants and animals need the help
of humans to eat and survive. Another major difference between a natural ecosystem and artificial
ecosystem is diversity. Natural ecosystems contain more natural factors and organisms. The
relationships between organisms, each other, and the environment in this ecosystem are more complex
than that of artificial ecosystems.
A Garden is an example of an artificial ecosystem made by humans while ponds, lakes and forests are natural ones.

a=8
d=3−8=−5
S22=n/2[2a+(n−1)d]
S22=22/2[2a+21d]
S22=11[2(8)+21(−5)]
S22=11(−89)
=−979.

Plasma membrane is a thin membrane that surrounds every living cell, separating it from the external environment around it. The plasma membrane consists of water-soluble substances like nucleic acids, proteins, carbohydrates. Typically, the plasma membrane defines the boundary of a cell. Apart from protecting the constituents of the cell, substances are exchanged through the surface of the plasma membrane.

Multiple fission in Plasmodium: It is an asexual mode of reproduction in organisms. Here, the nucleus of the organism divides repeatedly to form a number of equal-sized daughter nuclei and each daughter nuclei breaks away together with a small portion of the cytoplasm.

If sinA +cosA =1
cos A = 1 - sin A
then cos A-sin A= 1 - sin A - sin A = 1 - 2 sin A

No. Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons. Resistivity is the physical property of a particular substance which is having particular dimensions.
| Sl. No. | Differentiating Property | Resistance | Resistivity |
| 1 | Definition | Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons. | Resistivity is the physical property of a particular substance which is having particular dimensions. |
| 2 | Proportionality | Resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material. | Resistivity is only proportional to the nature and temperature of the particular material. |
| 3 | Symbol | R | ρ |
| 4 | Formula | R = V/I or, R = ρ(L/A)V = Voltage, I = Current, ρ = Resistivity |
ρ = (R×A)/L R = Resistance, L= Length, A = Cross-sectional area |
| 5 | SI Units | The SI unit of resistance is Ohms | The SI unit of resistivity is Ohms-meter. |

Difference between saturated and unsaturated hydrocarbons:
| Saturated hydrocarbons | Unsaturated hydrocarbons |
| Saturated hydrocarbons are the compounds containing only single covalent bonds. These are also known as alkanes. | Unsaturated hydrocarbons are the straight chain compounds containing double or triple covalent bonds. Hydrocarbons with a double bond between carbon atoms are known as alkenes. Hydrocarbons with triple bonds between carbon atoms are known as alkynes. |
| These compounds have more number of hydrogen atoms when compared to its corresponding unsaturated hydrocarbons. | These compounds have less number of hydrogen atoms when compared to its corresponding unsaturated hydrocarbons. |
| These compounds are less reactive. | These compounds are more reactive. |
| These compounds under go substitution reactions. CH4 + Cl2 → CH3Cl + HCl |
These compounds under go addition reactions. Ex: CH2=CH2 + H2 → CH3 - CH3 |
| Saturated hydrocarbons burns with blue flame | Unsaturated hydrocarbons burns with sooty flame |
