Answer:
Blood vessel dilation in the dermis is allowing increased blood flow from the deeper tissues to the skin.
Explanation:
Our skin feels hot when you have a fever because of the process known as vasodilation in which the widening of blood vessels occurs that increases the blood flow. Due to this process, blood flow to the skin increases that causes the temperature to rise and as as result sweating as well as dehydration occurs in order to remove heat from the body. So we can say that vasodilation is responsible for the increase in temperature of our body.

Explanation:
what is a sustainable resource?
The correct answer is D. An unmanaged resource that is limitless.
Explanation
Sustainable resources are those natural resources that can be used today without compromising the resources and possibilities of future generations. Sustainable resources are characterized for being limitless and not being produced by humans, that is, generated by nature, for example, solar energy, wind energy, hydraulic energy (from water), among others. Unlike non-renewable resources are those that have a limit, such as water, oil, natural gas, among others. Therefore, the correct answer is D. An unmanaged resource that is limitless.

Al cruzar 2 moscas negras se obtiene una descendencia formada por 216 moscas negras y 72 oscuras blancas. A) Razone el cruzamiento y determine fenotipo y genotipo.
Answer:
Fenotipo: Moscas negras y moscas blancas.
Genotipo: Nn y nn.
Explanation:
Sabemos que al cruzar dos moscas un pequeño porcentaje de su descendencia es blanca y la mayoría negra. Por ende, hay dos alelos distintos para el color, uno codifica para moscas de color negro y el otro para las de color blanco. Como la mayoría de la descendencia es negra, el gen domiante es el negro, a este lo denominaremos con la N y al recesivo con la letra n.
Para que haya moscas blancas, las dos moscas que se cruzan tienen que ser Nn, es decir, su genotipo tiene que ser heterocigoto. Podemos verificar esto con un cuadro de Punnett:
║N ║n
N║NN║Nn
n║Nn ║nn
Con el cuadro de Punnet vemos que la descendencia tiene los genotipo, es decir, los genes que un ser tiene, Nn y nn. El fenotipo, es decir, lo que podemos ver de los genes, sera moscas de color negro y moscas de color blanco.
Como el gen dominante es el negro, cualquier mosca con este gen expresara este color y solo las moscas con genotipo h0m0cigoto (nn) expresaran el color blanco.
What is a nucleotide? What is an amino acid? What is a simple sugar (glucose)? What do these three share in common?
Answer: The three mentioned substances (nucleotide, amino acid and glucose) are the BASIC UNITS of its various biological macromolecules.
Explanation:
NUCLEOTIDE is defined as the BASIC UNIT or the building block of nucleic acid such as Deoxyribonucleic (DNA) and Ribonucleic (RNA). It contains a sugar molecule, a phosphate group and a nitrogen containing base. They have a variety of functions which include:
--> they are the building blocks of substance that control hereditary characteristics.
--> energy carriers,
--> components of enzyme cofactors, and
--> chemical messengers.
AMINO ACID: This is defined as the BASIC UNIT that makes up the biological macromolecule known as PROTEIN which helps in the growth and repair of worn out tissues of the body.
It is made up of basic amino group, an acidic carboxyl group, and a unique organic side chain.
GLUCOSE: This is also the BASIC UNIT of the biological macromolecule called carbohydrates. They are also called simple sugars which are the body's preferred source of energy in the form of carbohydrates.
You discover a new protist species. It has chloroplasts and vacuoles and moves using a flagellum. How would you classify the way that it gets energy? Is it an autotroph, heterotroph, or both? Explain your answer
Answer:
Autotroph. Autotrophs include plants and some other creatures, vacuoles and chloroplasts are found in plants.
Explanation:
PLANTS! = Autotroph. I don´t even know anymore, it´s been 3 years since I took a basic science class, I am guessing from memory.
Do homologous structures always have the same function in different organisms?
Answer:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.

¿Qué tipo de célula apareció primero en la Tierra?:___, y se presentan en seres vivos como las:___ y se caracterizan porque:___. *
Answer:
Célula procariota y procariotas.
Explicación:
La célula procariota es un tipo de célula que apareció por primera vez en la Tierra hace unos mil millones de años. Estos tipos de células están presentes en los procariotas, lo que significa que estos organismos no tienen un núcleo verdadero o una membrana nuclear alrededor del núcleo y otros orgánulos de la célula. El ADN del organismo procariótico se encuentra en una parte central de la célula que se conoce como nucleoide. La pared celular de un procariota actúa como una capa adicional de protección, ayuda a mantener la forma y estructura celular y previene la deshidratación.

Which type of selection occurs when a population experiences a shift in diversity toward the larger organisms?
stabilizing selection
directional selection
disruptive selection
adaptive selection
Answer:
Directional selection
Explanation:
When a population experiences a shift in diversity toward the larger organisms, it is directional selection.
What is directional selection?The term directional selection has to do with a type of selection in which the specie tend towards one side of the population mean.
Therefore, when a population experiences a shift in diversity toward the larger organisms, it is directional selection.

In which Colorado Rockies scenario was there more erosion? Why was there more erosion in the scenario?
There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did.

Which process occurs within the mitochondria?
Answer:
Krebs cycle
Explanation:
The Krebs cycle is a set of chemical events that all aerobic organisms employ to generate energy by converting acetate (which comes from carbs, lipids, and proteins) to carbon dioxide. There are various alternatives to the TCA cycle in theory, but it appears that the TCA cycle is the most efficient.
Answer: Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria. ... In heart muscle cells about 40% of the cytoplasmic space is taken up by mitochondria.
Explanation:
The process is called oxidative phosphorylation and it happens inside mitochondria. In the matrix of mitochondria the reactions known as the citric acid or Krebs cycle produce a chemical called NADH. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).
