Based on Malthus’ research, Darwin indicated that the process of natural selection is a result of overpopulation because d. When there was overpopulation, there were more offspring than the environment could support.

Darwin's evolutionary theory of natural selection makes reference to the differential survival and reproduction rate of the most adapted phenotypes in a given environmental condition, which depends on the maximization of the available resources for this environment.

Moreover, Thomas Malthus developed the so-called Malthusian model of growth, which indicates that food production may not be enough to keep up with the growth of a given population of people.

Therefore, with this data, we can see that Darwin's evolutionary theory of natural selection is based on the existence of limited resources and the competence between the organisms for such resources in particular environmental conditions and factors.

Specific heat is defined by how much energy (in this case, heat) a specific object can hold/lose. In chemistry, the specific heat for water is 4.184 Joules per gram Kelvin. That means it takes 4.184 Joules of energy (heat) per gram (1 g) of water to gain heat by 1 Kelvin.

We can take specific heat and apply it to living organisms. We know that organisms must maintain homeostasis. A part of homeostasis is to maintain internal temperatures. Let's take the human body as an example organism. We have water inside our bodies. The specific heat of water is considered very high compared to other materials; this means that it takes a lot of energy to heat up water.

Answer:

it can't be used to make a protein in that cell.

Explanation:

If a gene is not transcribed in a cell, it can't be used to make a protein in that cell. If a gene does get transcribed, it is likely going to be used to make a protein (expressed). In general, the more a gene is transcribed, the more protein that will be made.

The transcription is affected as when the gene has not been transcribed the protein will not make. When a gene is transcribed, protein synthesis can happen.

Gene expression begins with transcription. To create an RNA molecule, the DNA sequence of a gene must be copied. RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).

A gene cannot be used to produce a protein in a cell if it is not transcribed there. If a gene gets transcribed, it will probably be used to produce a protein (expressed). In general, more protein will be produced the more a gene is transcribed.

Therefore, the transcription is impacted since the protein cannot be produced if the gene is not transcribed. Protein synthesis can take place when a gene is transcribed.

Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These  characteristics are passed on to their offspring.

According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.

Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.

Several tests have been evaluated in horses for quantifying insulin dysregulation to support a diagnosis of equine metabolic syndrome. Comparing the performance of these tests in the same horses will provide clarification of their accuracy in the diagnosis of equine insulin dysregulation. The aim of this study was to evaluate the agreement between basal serum insulin concentrations (BIC), the oral sugar test (OST), the combined glucose-insulin test (CGIT), and the frequently sampled insulin-modified intravenous glucose tolerance test (FSIGTT). Twelve healthy, light-breed horses. Randomized, prospective study. Each of the above tests was performed on 12 horses. Minimal model analysis of the FSIGTT was considered the reference standard and classified 7 horses as insulin resistant (IR) and 5 as insulin sensitive (IS). In contrast, BIC and OST assessment using conventional cut-off values classified all horses as IS. Kappa coefficients, measuring agreement among BIC, OST, CGIT, and FSIGTT were poor to fair. Sensitivity of the CGIT (positive phase duration of the glucose curve >45 minutes) was 85.7% and specificity was 40%, whereas CGIT ([insulin]45 >100 μIU/mL) sensitivity and specificity were 28.5% and 100%, respectively. Area under the glucose curve (AUCg0-120 ) was significantly correlated among the OST, CGIT, and FSIGTT, but Bland-Altman method and Lin's concordance coefficient showed a lack of agreement. Current criteria for diagnosis of insulin resistance using BIC and the OST are highly specific but lack sensitivity. The CGIT displayed better sensitivity and specificity, but modifications may be necessary to improve agreement with minimal model analysis. Copyright © 2016 The Authors.

Explanation: Sorry if this is not correct.

Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.

In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.

Competition leads to differential survival and reproductive success among individuals.

Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.

These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.

Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.

Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.

Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.

Answer:

The hypothalamus triggers the sympathetic nervous system after receiving a distress signal from the amygdala by communicating with the adrenal glands via the autonomic nervous system. In response, these glands release the hormone epinephrine, also referred to as adrenaline, into the bloodstream.

Answer: The fight-flight response is a physiological reaction that occurs in response to a perceived threat or danger. It is a complex process that involves the nervous system and the endocrine system, working together to maintain homeostasis in the body.

The nervous system detects the threat and initiates the response. When a threat is detected, the sympathetic nervous system is activated. This results in the release of adrenaline and noradrenaline from the adrenal glands, which are part of the endocrine system. These hormones help prepare the body for action by increasing heart rate, increasing blood pressure, and increasing blood glucose levels.

At the same time, the hypothalamus in the brain is also activated. This triggers the release of corticotropin-releasing hormone (CRH), which in turn stimulates the pituitary gland to release adrenocorticotropic hormone (ACTH). ACTH stimulates the adrenal cortex to release cortisol, which helps to maintain blood glucose levels and promote the mobilization of energy stores.

Together, the nervous system and the endocrine system work to coordinate the fight-flight response. The sympathetic nervous system increases heart rate and blood pressure, while the adrenal glands release adrenaline and noradrenaline to help prepare the body for action. At the same time, the hypothalamus and pituitary gland release CRH and ACTH, respectively, which stimulate the release of cortisol to maintain blood glucose levels and promote energy mobilization.

Once the perceived threat has passed, the parasympathetic nervous system is activated to help return the body to its normal state, and the endocrine system stops releasing stress hormones. This coordinated response by the nervous system and the endocrine system helps to maintain homeostasis in the body during times of stress and danger.

The environmental sciences have documented large and worrisome changes in earth systems, from climate change and loss of biodiversity, to changes in hydrological and nutrient cycles and depletion of natural resources. These global environmental changes have potentially large negative consequences for future human well-being, and raise questions about whether global civilization is on a sustainable path or is “consuming too much” by depleting vital natural capital (13). The increased scale of economic activity and the consequent increasing impacts on a finite Earth arises from both major demographic changes—including population growth, shifts in age structure, urbanization, and spatial redistributions through migration and rising per capita income and shifts in consumption patterns, such as increases in meat consumption with rising income (19, 20).
