In the double strand DNA nitrogenous bases paired in a specific manner, A (Adenine)always pairs with T (Thymine) with double hydrogen bond or vice-versa and C (Cytosine) pairs with G (guanine) with triple hydrogen bond or vice-versa.

The correct answer for this question is TRUE

Ecological succession is the process of change in structure of an ecological species by pre-existing community over time. We can say that in ecological succession, each new community is paving a way for new community. The different types of ecological succession exists during different phases of an ecosystem, and depends on how developed that ecosystem is. Succession that begins in new habitat, uninfluenced by pre-existing community is called primary succession whereas succession that follows disruption of a pre-existing community is called secondary succession.

Answer:

Option (B)

Explanation:

A river that is diverted to the irrigating farmland during a drought is an example of the human-caused disturbances to an ecosystem.

An ecosystem refers to a particular community within which the organisms exist and interact with each other. For example, fresh water ecosystem, desert ecosystem and forest ecosystem.

In the given situation, the river channel is disturbed by changing its flow direction. This is caused by the human activity, that changes the course of the river channel to the farmlands during a flood, so that the water can provide nutrient to the soil and prevent the soil from getting eroded.

Thus, by doing this, the river ecosystem gets affected, as a result of which the organisms existing in this ecosystem such as fishes are affected.

Hence, the correct answer is option (B).

A business cycle is a recurring pattern of expansion and contraction in economic activity over time.

- Phases: The business cycle consists of several distinct phases, including expansion, peak, contraction, and trough.

- Expansion: During the expansion phase, economic activity, such as production, employment, and spending, increases, leading to growth in the economy.

- Peak: The peak marks the highest point of the business cycle, where economic activity reaches its maximum level before starting to decline.

- Contraction: Following the peak, the economy enters a contraction phase characterized by a decline in economic activity, such as falling production, rising unemployment, and reduced spending.

- Trough: The trough represents the lowest point of the business cycle, where economic activity reaches its lowest level before starting to recover.

- Factors: Various factors influence the business cycle, including changes in consumer and business confidence, government policies, technological advancements, and external shocks such as natural disasters or geopolitical events.

- Policy Response: Governments and central banks often implement fiscal and monetary policies to mitigate the effects of economic downturns and promote recovery during economic contractions, aiming to stabilize the business cycle and achieve sustainable economic growth.

Population Density is directly related to the science of ecology. So, the correct option is (D).

Population density is defined as the average number of individuals per unit population of area or volume. For example, a population density of 100 red ants living in an area of ​​100 square meters is 1 ant per square meter.

Ecology attempts to understand the relationship between living organisms such as plants, animals, microorganisms and their environment . Population density refers to the number of individual organisms in a unit area of ​​space.

Population density = Total Population / Area of ​​residence

Thus, Population Density is directly related to the science of ecology. So, the correct option is (D).

Answer:

Gases have more kinetic energy than liquids. Liquids have more kinetic energy than solids. When a substance increases in temperature, heat is being added, and its particles are gaining kinetic energy. Because of their close proximity to one another, liquid and solid particles experience intermolecular forces.

Answer:

the answer is b. scarcity of drinking water

Explanation:

Answer: B.The aquatic species’ populations will decrease, and the ecosystem’s carrying capacity will increase.

Explanation:

Limiting factor can be define as the factor which is capable of reducing the population of a species. Carrying capacity can be define as the maximum number of the population of a species that a region or ecosystem can support in terms of availability of resources. The construction of a dam is likely to disturb the native habitat of the living species in the river. As it is going to cut the part of river. The construction of a dam is a limiting factor for aquatic animals species. Due to the decrease in the population of native animals the carrying capacity of a region will increase .

Final answer:

Dam construction impacts aquatic species populations and the ecosystem's carrying capacity by decreasing both due to altered river conditions and habitat loss.

Explanation:

The likely outcomes for the populations of aquatic species and the ecosystem's carrying capacity due to dam construction:

The aquatic species' populations will decrease due to altered river conditions, reduced flow, and habitat loss.

The ecosystem's carrying capacity for the aquatic species will decrease as the habitat is cut off, affecting the overall biodiversity and ecosystem health.

Therefore, option B The aquatic species’ populations will decrease, and the ecosystem’s carrying capacity will increase is the most likely outcome for the populations of aquatic species and the ecosystem's carrying capacity.

Final answer:

The water in the ocean can become rain or snow in the mountains through the water cycle, starting with evaporation, followed by condensation into clouds, and falling as precipitation. Snow can remain on mountains and become part of glaciers, and eventually, gravity returns this water via rivers back to the ocean.

Explanation:

The water in the ocean can become part of the precipitation that falls as rain or snow on the mountains through natural processes such as the water cycle. This cycle includes the evaporation of water from the ocean's surface, facilitated by the heat from the Sun. The water vapor rises into the atmosphere and cools, leading to the condensation of water around microscopic particles, forming clouds. Through a process called precipitation, water droplets grow and eventually fall to Earth as rain, snow, sleet, or hail based on the temperature and conditions in the atmosphere.

Some precipitated water falls on mountains where it can stay as snow and may become part of glaciers. Over time, due to sublimation, the process in which a solid changes directly into a gas, some of the water from snow and ice may go directly back into the air. Eventually, gravity guides this water, whether it fell as snow or rain, down mountains to rivers and back to oceans.

Explanation:

The correct answer is diffusion.

Aquatic respiration refers to the procedure whereby an aquatic animal attains oxygen from water. Fish and other aquatic species utilize gills to consume oxygen dissolved in the water and diffuse carbon dioxide out of the bloodstream.

Diffusion is a procedure in which a substance moves from a region of high concentration to the region of low concentration until equilibrium is attained. In the case of aquatic species, blood with a low concentration of oxygen molecules moves through the gills. The concentration of the oxygen molecules in water is greater in comparison to the concentration of oxygen molecules in the gills.

As a consequence, the molecules of oxygen diffuse from water (higher concentration) to a region of lower concentration, that is blood. In the same manner, the molecules of carbon dioxide diffuse from the blood, that is, high concentration to water, that is, low concentration.
