Explanation:

Genetic drift refers to the random fluctuation of allele frequencies in a population, which occurs due to chance events. This process is often referred to as the “sampling error” in genetics.

Genetic drift can have a significant impact on small populations, where random events can lead to the loss or fixation of alleles. It is an evolutionary mechanism that can lead to the loss of genetic diversity and the divergence of populations over time.

Genetic drift occurs when the frequency of certain alleles changes randomly from one generation to the next. This process can be caused by several factors, including genetic bottlenecks, founder effects, and random mutations. As a result of genetic drift, some alleles may become more common in a population, while others may become less common or even disappear.

Genetic drift is particularly important in small populations, where chance events can have a significant impact on the genetic makeup of the population. In contrast to natural selection, genetic drift does not lead to adaptations or changes in response to environmental pressures. Instead, it is a purely random process that can cause unpredictable changes in allele frequencies over time.

Answer:

D. Pathogen

Explanation:

Changes in phenotype that are not related to changes in the DNA and that may result from the interaction between the genotype and the environment are known as phenotypic plasticity.

Phenotypic plasticity refers to the ability of an organism to express different phenotypes in response to environmental conditions, without any changes in its DNA sequence.

Phenotypic plasticity is a crucial mechanism that allows organisms to adapt and survive in different environments. It allows individuals with the same genotype to have different phenotypes, enabling them to respond to changes in their surroundings. This flexibility can be observed in various traits such as behavior, morphology, and physiology.

The genotype provides the basic blueprint for an organism's development, but the environment plays a significant role in shaping the final phenotype. Environmental cues can trigger specific gene expression patterns, leading to the development of different phenotypes. For example, temperature can influence the coloration of certain reptiles, with warmer temperatures resulting in darker skin tones.

Phenotypic plasticity is particularly prevalent in organisms with a wide range of habitats. It allows them to exploit various resources and cope with changing conditions. This flexibility can be seen in plants adjusting their growth patterns in response to light intensity or animals changing their reproductive strategies in response to population density.

It is important to note that phenotypic plasticity is not the same as genetic adaptation. Genetic adaptation involves changes in the DNA sequence through natural selection, whereas phenotypic plasticity is a reversible response to the environment.

In conclusion, changes in phenotype that are not related to changes in the DNA can occur due to phenotypic plasticity, which is the result of interactions between the genotype and the environment. This mechanism allows organisms to adjust their phenotypes in response to changing environmental conditions, enhancing their ability to survive and reproduce.

Explanation:

Answer:

Study of stars

Explanation:

it's dated back to the 6th century BC. Detailed records of observations were kept from about the 6th century BC, until the introduction of Western astronomy and the telescope in the 17th century. Chinese astronomers were able to precisely predict eclipses. Much of early Chinese astronomy was for the purpose of timekeeping.

The population after 40 years will be 400,000 animals, and the population after 65 years will be approximately 336,000 animals.

To determine the population after a certain time period, we can use the formula for exponential decay;

N(t) = N0 × \((1/2)^{(t/T)}\)

Where;

N(t) is the population at time t

N0 is the initial population

t is the time elapsed

T is the half-life of the population

Given;

N0 = 1.6 million

T = 20 years

Let's calculate the population after 40 years;

N(40) = 1.6 million × \(1/2^{(65/20)}\)

= 1.6 million × (1/2)²

= 1.6 million × (1/4)

= 400,000

Therefore, the population after 40 years will be 400,000 animals.

Now, let's calculate the population after 65 years;

N(65) = 1.6 million × \((1/2)^{(65/20)}\)

= 1.6 million × \((1/2)^{(13/4)}\)

≈ 1.6 million × 0.210

≈ 336,000

Therefore, the population after 65 years will be approximately 336,000 animals.

Answer:

If Earth's resources were completely used up, the human population could face serious consequences, including food and water shortages, energy crises, and economic instability. In the long term, it could lead to a decline in human numbers and potentially even extinction. Therefore, it is important to manage Earth's resources sustainably, to ensure their availability for future generations.

Answer:

If Earth's resources were completely used up, the consequences for the human population would be severe.

Firstly, the availability of basic necessities such as food, water, and energy would become scarce, leading to widespread famine, thirst, and lack of power. The depletion of resources such as oil, natural gas, and coal would cause the collapse of modern transportation, industry, and communication systems, leading to widespread poverty and social upheaval.

Moreover, without natural resources such as forests, minerals, and fertile soil, the human population would face environmental degradation and loss of habitat. This would lead to a decline in biodiversity and a reduction in the availability of essential ecosystem services, such as pollination and pest control.

In addition, the depletion of resources could lead to conflicts over the remaining resources, with countries, communities, and even individuals vying for control of the dwindling supplies. This could result in war, violence, and mass migration, leading to further instability and suffering for the human population.

In conclusion, if Earth's resources were completely used up, the consequences for the human population would be far-reaching and devastating, with severe impacts on health, security, and well-being.

When catalase is introduced to hydrogen peroxide, a fast evolution of oxygen occurs for roughly two minutes, depending on the peroxide concentration.

Following that, oxygen is released at a constant rate that gradually drops over an hour.
