The answer is D. The Tasimain devil and wolverine.....
B) contraction of body hair muscles
C) thyroid hormones increase basal metabolic rate of cells in the body
D) blood vessels dilate and blood is directed to the superficial layers of the skin
Blood vessels dilate and blood is directed to the superficial layers of the skins is one way in which the body will react to maintain homeostasis.
Homeostasis is the set of self-regulation phenomena that lead to the maintenance of constancy in the properties and composition of the internal environment.
Control in blood flow is a response that reduces heat transfer and therefore maintains body temperature.
Thermoreceptors upon detecting an increase in body temperature, are activated and transmit this information to the hypothalamus that receives the information.
Blood vessels constrict to reduce the passage of "warm" blood to the skin, allowing it to be used in vital organs.
Blood vessels in the skin dilate as a result of increased body temperature, allowing molecules to separate and occupy more space.
In addition, it increases the amount of warm blood that flows from inside the human body, increasing blood pressure and transmitting heat to the outside environment more quickly.
This allows body temperature to be lowered, a notorious consequence of this dilation of the vessels is the reddening of the skin where there is greater flow and transfer of body heat.
Therefore, we can conclude that blood vessels dilate and blood is directed to the superficial layers of the skins is one way in which the body will react to maintain homeostasis.

Before forming a hypothesis, an individual firstly makes an observation and formulates a question. Conducting some research follows, which aids in the formation of a hypothesis. A hypothesis, which is an educated guess, predicts the outcome of a situation.
The steps leading up to the formation of a hypothesis typically involve first making an observation about the natural world. This could include noting a trend, pattern or single event. From this observation, questions might arise that the observer seeks to answer. Following observation and question formulation, the next step is often to conduct some research about the topic which can inform the creation of a hypothesis. A hypothesis is a testable statement that predicts the outcome of a situation given certain conditions, often presented in an "If... then..." format. It serves as an educated guess to explain the initial observation.

the Earth is the center of the universe
the moon is the center of the solar system
the solar system has no center
The geocentric model of the universe states that the Earth is the center of the universe.
The geocentric model of the universe states that the Earth is the center of the universe. This model was widely believed for many centuries until the heliocentric model proposed by Nicolaus Copernicus was accepted. The geocentric model was based on observations of the apparent movement of celestial objects and was supported by the teachings of ancient Greek philosophers such as Aristotle and Ptolemy.
This model indeed prevailed for centuries in human understanding until the heliocentric model, which placed the Sun at the center, gained acceptance through the work of astronomers like Nicolaus Copernicus and Johannes Kepler. The geocentric model's historical significance and eventual replacement are essential aspects of the history of astronomy and our understanding of the cosmos.

An organ system is a group of organs that cooperate to perform a specific function or set of functions. The human body has 11 major organ systems, each with a unique role in maintaining health and function.

Chloroplasts are present only in plant cells. The chlorophyll found in the chloroplast is responsible for its green pigment and where phtotsynthesis takes place. They are oval in shape with outer and inner membranes. The inner membrane surrounds the stroma and grana.
