Biotic potential and environmental resistance determine the carrying capacity.
The maximum capacity of reproduction of a species under adequate environmental conditions is known as biotic potential. On the other hand, environmental resistance is a factor or things that restrict the growth of a population. These comprise disease, predators, lack of food, and competition.
These both determine the carrying capacity of a species. It is the maximum size of the population of the species, which the environment can maintain indefinitely, provided the habitat, food, and other important components accessible in the surroundings.
B) it gets more direct sunlight.
C) the Earth is closer to the Sun.
D) it is tilted away from the Sun.
Answer:
Option (B)
Explanation:
When the tilt of the earth is towards the sun, then it is called summer in the northern hemisphere. In this position, the sunlight is directly over the earth, as a result of which it absorbs more amount of heat. Spring is the season that starts from about 21st March to 21st of June or it can be considered as the season that exists between the summer and winter. Here, a high amount of sunlight is absorbed due to which the temperature eventually rises.
This is the reason why the northern hemisphere is relatively warmer during the spring season than in winter.
Hence, the correct answer is option (B).
The characteristics that is not shared in all living things is movement. The correct option is C.
While it is a property frequently linked to a variety of living things, not all living creatures have the ability to move.
There are many examples of living things that move very little or not at all over the course of their existence. For instance, plants are living things that often move very little or stay planted in one location. It's possible for microorganisms like bacteria or fungi to move very little.
However, all livingbeings also share the other traits listed in the choices.
All living things are formed of cells, which serve as the basic structural and functional units of life. This is referred to as a cellular organisation.
Thus, the correct option is C.

A cellular organization is the characteristics that not all living things share. This is because most of the unicellular organisms don’t have cellular organization.
The part of cell and how these individual parts are arranged within the cell makes up the cellular organization.
Cell is the basic unit of life and it has two types.
Prokaryotic cells are cells with smaller sizes with a greater surface to volume ratio, which implies that nutrients can get to any part within the cell interior easily. Prokaryotic cells does not have nucleus. They are unicellular (single cell organisms) and they include bacteria and archaea. However, archaea lives in environments that are extreme.
Eukaryotic cells are cells with larger sizes, which means lesser-surface to volume ration and there is no easy or rapid diffuse of nutrients. In eukaryotic cells, a specialized internal organelles put together in an organized manner is required to metabolism to take place, to generate energy and moves chemical within the cell. Eukaryotic also refers to organism that has eukaryotic cell. Cells shapes and sizes vary.
The Basic cellular components of cells include:

The ability to rust is not a physical property of iron because rusting change the chemical composition of iron.
Therefore, the ability to rust is not a physical property of iron.

Answer:
The correct reason would be "the levels of dissolved oxygen at the mouth of the river and at the source of the river".
The mouth of the river is the region where it flows into the ocean, lake, another river, reservoir, sea et cetera. The level of dissolved oxygen in this region is too low to support great biodiversity.
Organisms like catfish and carp can survive here due to their low oxygen demand. For example, catfish can survive in water with an oxygen content of 2.5 parts per million.
In contrast, the level of dissolved oxygen is higher at the source of the river. Organisms like trout are found here due to their high oxygen need. For example, rainbow trout require minimum 5-6 parts per million dissolved oxygen for its survival.
