Answer:

A

Explanation:

Natural selection is the process through which populations of living creatures adapt and change. Therefore option (A) is the correct answer.

Natural selection refers to the process in which different individuals with distinct phenotypes have variable rates of survival and reproductive success. The gradual shift, over the course of generations, of the heritable characteristics that are typical of a population is an important aspect of the evolutionary process known as evolution.

In the process of evolution, four fundamental ideas are at play: variation, heredity, selection, and the passage of time. Natural selection is widely regarded as the key evolutionary mechanism, and these are its constituent parts.

Answer: The primary threats currently facing blue whales are vessel strikes and entanglements in fishing gear .Also illegal hunting.

Explanation:

Answer:

Blue whales were significantly depleted by commercial whaling activities worldwide. The latest stock assessments of blue whales include data for various stocks, including areas of the North Pacific and western North Atlantic Oceans.

Whaling killed hundreds of thousands of blue whales from the early 1900s until it became illegal in 1966. Blue whales continue to be threatened by boats, anthropogenic noise, pollution with toxic chemicals, climate change (which may affect how the population of krill), and from fishing.

Answer and explanation:

Animal cells do not have cell walls or chloroplasts but both plant and animal cells contains nucleus and cell membrane.

Biochemical similarities among organisms are studied primarily through D) DNA sequences. DNA sequences contain genetic information that can be compared across different species to reveal similarities and evolutionary relationships.

By analyzing and comparing these sequences, scientists can identify conserved regions and specific variations that may indicate shared ancestry or common evolutionary paths. While observations of plant and animal behavior, fossil records, and studying cells under a microscope are all valuable tools in studying biology and evolution, they do not specifically address biochemical characteristics.

DNA sequencing directly examines the molecular basis of life, allowing for a deeper understanding of the biochemical relationships between organisms. This method provides concrete evidence of genetic similarities and can be used to construct phylogenetic trees, which display the evolutionary connections between various species.

In summary, to study biochemical similarities among organisms and their relationships, DNA sequences are the most appropriate method. This approach allows for a direct examination of genetic information, providing insights into evolutionary relationships and shared ancestry. Hence, D is the correct option.

Evolution is a change in the body structure of living things that takes place slowly over a very long time.

The ability to run very fast Cheetah because Cheetah has an ideal body, slim, and long legs. In addition, Cheetahs have a flexible spine so they can run at high speed. In the process of evolution, the cheetah, which has short legs with the ability to run, is being selected by nature because it is unable to catch its prey. Meanwhile, cheetahs that are able to run fast and have long legs continue to survive and show these traits to their offspring.

Explanation:

Move in and out of the cell

An isotonic solution has been the type of solution that has the same concentration. If a cell is placed in an isotonic solution, water will move in and out of the cell. Thus, option D is correct.

An isotonic solution has been the type of this solution that has been defined by the concentration of the salt that is the same as the outer and the inner environment across the membrane. They are majorly used as IV fluids.

The isotonic solution allows the nutrients and electrolytes to move in and out of the cell easily for the body to perform various functions. The cell does not swell or shrink, unlike the hypotonic or hypertonic solution, where the concentrations are high and low.

A dense concentration of plants exists, resulting in extremely high GPP and NPP. As a result, increased productivity increases biomass.

Tropical rainforests are densely packed with flora and other living species, yet the soil is depleted of nutrients due to the large amount of precipitation.

The majority of the carbon and vital nutrients in the rainforest are locked up in the living flora, dead timber, and decaying leaves. Because organic material decays so quickly, little nutrients reach the soil, leaving it nearly sterile.

Many tropical rainforest soils are extremely depleted and infertile. Millions of years of weathering have swept away the majority of the nutrients out of the soil.

The type of diversity that I have chosen is ‘Gender Diversity’ and  below are the reasons why it is essential as a factor in my opinion.

Gender diversity refers to the representation of both men and women in the workplace and society as a whole. It includes people of all genders, including non-binary individuals. Gender diversity has a significant impact on the workplace and society in general. As women are still underrepresented in many industries and roles, increasing gender diversity can lead to more opportunities for women and help break down gender stereotypes.

By having a gender-diverse workplace, companies can ensure compliance with these laws and avoid penalties or legal issues in the future.In conclusion, gender diversity is essential because it promotes a more inclusive environment, encourages innovation and creativity, and leads to better decision-making. By having a gender-diverse workplace, companies can improve employee satisfaction, increase profitability, reduce discrimination and biases, and ensure compliance with laws related to gender diversity.

Some examples of short-term environmental changes are drought, flooding, smog and pollution et-cetra.

Hence, the correct option is D)

Answer:

D

Explanation:

An ecosystem has the potential to be sustainable over a long time period because it is comprised of interconnected components that can self-regulate, maintain balance, and adapt to changes in the environment.

An ecosystem is a complex network of living organisms, their interactions, and the physical environment in which they exist. It possesses inherent mechanisms that contribute to its sustainability. Firstly, ecosystems are characterized by a high level of biodiversity, with a variety of species occupying different niches. This diversity ensures the availability of alternative pathways for energy flow and nutrient cycling, reducing the risk of ecological imbalances caused by the loss of a single species.

Secondly, ecosystems have self-regulatory processes that help maintain balance and stability. Negative feedback loops, such as predator-prey interactions, nutrient recycling, and natural selection, allow the ecosystem to adjust and recover from disturbances or fluctuations in population sizes.

Lastly, ecosystems possess the capacity to adapt to changes in the environment. Through evolutionary processes, organisms can undergo genetic changes and develop new traits that enhance their survival and reproduction. This adaptability allows ecosystems to withstand environmental pressures and maintain their functioning over extended periods.

In combination, the interconnectedness, self-regulation, and adaptive capacity of an ecosystem provide the foundation for long-term sustainability. However, it is important to note that human activities, such as habitat destruction and pollution, can disrupt ecosystem dynamics and pose threats to their long-term viability.
