: How does a resilient system respond to a disturbance? By contracting and becoming smaller. By reisisting change. It maintains its overall identity and species diversity is preserved. It reorganizes its functions immediately, resulting in species loss. Community structure is unaffected, there is no change.
Answers
A resilient system typically responds to a disturbance by reorganizing its functions and maintaining its overall identity while preserving species diversity. The correct answer is option b.
Resilience refers to the ability of an ecosystem to withstand and recover from disturbances and while doing so the resilient system maintains its overall identity and keeps its species diversity preserved. This means that when a disturbance happens in a resilient system, it doesn't necessarily lead to a loss of species. Rather, the system has the ability to adapt to the disturbance while preserving its identity and species diversity.
The maintenance of species diversity and identity is important for the continued survival of the system. This is because species in a system interact in complex ways, and the loss of one species can have a ripple effect throughout the system, leading to further species loss and ultimately, the collapse of the system.
Therefore, option ''b'' is the correct answer.
The question should be:
How does a resilient system respond to a disturbance?
a. By contracting and becoming smaller.
b. By reorganizing its system It maintains its overall identity and species diversity is preserved.
c. It reorganizes its functions immediately, resulting in species loss.

Answers
Answer:
The correct answer is option A ( a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH.)
Explanation:
Ketoacidosis results in a type of body metabolic state where the urine concentrations are high in ketone bodies, such as acetoacetic acid , 3-hydroxybutyrate. Fatty acids are converted to ketone bodies, resulting in a very high level of ketone bodies which automatically lowers the blood pH.
Ketoacidosis is of different types, Diabetic ketoacidosis, alcoholic ketoacidosis, starvation ketoacidosis. They are all associated with the accumulation of ketone bodies within the bloodstream. The underlying disease common with ketoacidosis is Diabetes.

Name one way in which soil depends on a biotic factor.
Answers
Answer:
Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead.
Explanation:
Abiotic and biotic elements, as well as other components, make up the complex and dynamic system known as soil. Living elements of the soil, such as plants, animals, and microorganisms, are referred to as biotic factors.
What is the way to create a complex and a dynamic system ?A complex and dynamic system is created by the interactions between these living elements and the soil's abiotic elements, such as water and minerals. The cycle of nutrients is one way that soil is dependent on a biotic component.
The process of moving nutrients through the soil and its biotic elements is known as nutrient cycling. When plants and other living things die or are consumed by other living things, they return nutrients from the soil to it.
This round for soil fertility and general soil health to be maintained, nutrient uptake and release are crucial. As they decompose organic matter and release vital nutrients into the soil, soil microorganisms also play a significant part in this process.
Soil wouldn't be able to support the growth of plants and other organisms without this nutrient-cycling process.

describe and explain the adaptations of sperm and ovum that enables fertilisation and early development of the embryo to occur
Answers
The adaptations of the sperm and egg that allow fertilization to take place, and copulation occurs for the sperm to be deposited. These sperm penetrate the cervix and travel to the fallopian tube. There, they must find an oocyte, which is released in the process of ovulation.
What is fertilization and embryo development?In the first weeks after fertilization, the zygote makes many changes and develops rapidly. The first eight weeks of development is known as the organogenic period and is the embryonic stage of development. This period is a crucial phase of development for the embryo's organs.
With this information, we can conclude that The first three days of embryonic development occur in the fallopian tube as the embryo moves from the ovary to the uterus. Cell division continues and forms a hollow ball of cells (the blastocyst). Six days after fertilization, the embryo begins implantation into the lining of the uterus.

Many segments are blank wholesome are blank such as a segment for digestion and a segment for reproduction
Answers
Many Body segments are very wholesome are essential such as a segment for digestion and a segment for reproduction.
What is the bodily systems about?In the above case, it would be more accurate to say that many bodily systems are essential for our overall health and well-being, and they each play important roles in maintaining our bodily functions. For example, the digestive system is responsible for breaking down food and absorbing nutrients, while the reproductive system is responsible for producing and delivering offspring.
Therefore, It is important to note that while some bodily functions or segments may be considered more "wholesome" than others, each system is necessary and contributes to the overall functioning of the body. So, rather than categorizing them as wholesome or not, it's more useful to think of them as essential components of a complex and interconnected system.

A) Stabilizing, directional, and disruptive
B) Physical, chemical, and organic
C) Genetic, hereditary, and environmental
D) None of the above
Answers
Stabilizing selection, directional selection and disruptive selection are the three types of natural selection.
What are these types of selection?
Natural selection is the process wherein organisms get better adapted to their environments and tend to survive and produce more offsprings. It is basically a mechanism of evolution which favors those organisms that can better adapt to their environment.
Directional selection: this theory states that an extreme phenotype (a characteristic or trait) is favored over other phenotypes and this causes the allele frequency to shift in favor of the extreme phenotype over time. A particular trait, if favorable, will be expressed in the population at the most beneficial frequency.
Stabilizing selection: in this type, meaning a non-extreme trait is favored instead of one of the two extreme traits. Stabilizing selection is said to be the most common mechanism for natural selection, because most traits do not change drastically over time.
Disruptive selection: This selection is bimodal. It favors both of the extreme traits in a population.
So therefore, stabilizing selection, directional selection and disruptive selection are the three types of natural selection.

The exponential form of growth is indicated by the J-shaped growth curve for a species' population growth. The favorable variables have caused the growth rate to climb quickly.
Explain abut the J shaped curve?American sociologist James C. Davies first proposed the J-curve hypothesis in 1962. He thought that social and political discontent was caused by a brief period of significant decrease in economic development following a protracted era of economic growth and improvement.
The j-shaped development curve known as a "J curve" is a visual representation of a situation in a novel environment when an organism's population density rises exponentially.
The population size, N, produces a J-shaped growth curve when it is plotted over time. This demonstrates that the number of people added with each reproduction generation is increasing more quickly.

If you took a 20-foot tree and hammered a spike into it 3-feet above the ground, how high would that spike be 30 years later when the tree is 100 feet tall? and why?
Answers
Answer:
The spike will remain at 3-feet above the ground in 30 years time because the spike does not increase in height as the tree does.
Please find the explanation below
Explanation:
Living things including the trees stated in this question are capable of growth (in height and girth). According to this question, a spike is hammered into a tree base at 3-feet above the ground level. However, after 30 years, the tree grows to 100 feet but the spike will remain at 3-feet above the ground.
This is because the spike, which is naturally incapable of growth, will not grow alongside the tree. A plant (tree) undergoes growth at its apices or meristem i.e. the tree will elongate from the tip and not any other part. Hence, the tree will grow and leave the spike at its initial level.
