Which of the following is not one of the seven primary odors humans recognize?
fresh
putrid
pungent
roses
Answer:
roses
Explanation:
It occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system.2 Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion.3
There are many different causes for alteration, lack, or disturbance to a normal sense of smell, and can include damage to the nose or smell receptors, or central problems affecting the brain. Some causes include upper respiratory infections, traumatic brain injury, and neurodegenerative disease.
Answer:
Fresh
Explanation:
When you look at the chartr, Roses were cconsidered a floral scent, which was listed, then there was putrid, pungent, and 3 others, the only one that wasn't listed was fresh, because often out scent and taste work together to help us find rotten foods, but we find that by smelling putrid scents or pungent scents, rather than fresh scents. Therefor the correct response is fresh

Will pigs ever fly?
Support your answer with suitable examples.
Answer:
NO
Explanation:
the pigs will never be able to fly as the birds have:
wings – these enable the force of lift.
lightweight, smooth feathers – this reduces the forces of weight and drag
streamlined body – this helps reduce the force of drag (a shape that lowers the friction drag)
light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight
Meanwhile the pig is obviously heavier, having a stronger force of gravity, and does not have the same type of "lightweight" bones that the birds have.
Answer:yes they might
Explanation:
Birds are able to breed with pigs and pigs might get wings

The rising of bread dough is the result of The rising of bread dough is the result of oxygen being released. carbon dioxide produced by fermentation. biotin production. oxidative phosphorylation.
Answer:
Fermentation
Explanation:
Fermentation is the process whereby carbohydrates are converted to acohol or acid by the activities of some enzymes. During the process of fermentation, carbon dioxide is produced and it is found as tiny pockets of air inside the bread dough. This make it to rise. The alcohol produced evaporates later during the bread making process.

Question 4 of 16 Which chemical equation models a synthesis reaction ? O A. 2Na+MgCl 2 2NaCl+Mg O B. H 2 O+CO 2 H 2 CO 3 C. HCl+LiOH LiCl+H 2 O O CO 2 C+O 2
Answer:
The chemical equation which is a model of synthesis reaction is option B
B. H₂O + CO₂ ---> H₂CO₃
Explanation:
A synthesis reaction is a type of chemical reaction in which two or more reactants combine to form a single product.
A synthesis reaction is illustrated below:
A + B ----> C
In the illustration above, A and B are two chemical substances which serve as the reactants in the chemical reaction. A and B combine with each other to form a product C.
Common synthesis reaction include:
1. The reaction of sodium with chlorine to produce sodium chloride: Na + Cl ---> NaCl
2. The synthesis of Nitrogen (iv) oxide from nitrogen (ii) oxide and oxygen: 2NO + O₂ ---> 2NO₂
3. The synthesis of sulfur trioxide from sulfur dioxide and oxygen: 2SO₂ + O₂ ----> 2SO₃
From the given chemical reactions, the model of a synthesis reaction is option B
H₂O + CO₂ ---> H₂CO₃

Forces occur in action-reaction pairs.
A. 1st Law
B. 2nd Law
C. 3rd Law
Answer: C (3rd law)
Explanation:
Newton's third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel out.

Which action can trigger lactic acid fermentation in our bodies?
A.
drinking coffee
B.
reading a book
C.
running a marathon
D.
sleeping
E.
watching a movie
Answer:
C. running a marathon
Explanation:
When you run a marathon you eventually switch to anaerobic respiration since not enough oxygen is present for aerobic respiration to occur (which uses oxygen as the last electron carrier in the electron transport chain). This process causes lactic acid to be produced.
Answer:
running a marathon

ADAPTACIÓN
Elige un ser vivo y desarrolla sus características comunes con el resto de los seres vivos (formado por células, nutrición, reproducción, respiración, adaptación)
Answer:
- Célula >> unidad básica y funcional de todos los seres vivos
- Nutrición >> proceso de toma de nutrientes del medio ambiente
- Reproducción >> proceso de replicación con el fin de perpetuar la especie
- Respiración >> proceso de intercambio gaseoso en organismos superiores
- Adaptación >> mecanismo por el cual los organismos se ajustan a su ambiente
Explanation:
Un mamífero (por ejemplo, un perro) es un organismo multicelular compuesto por diferentes tipos de células especializadas las cuales se asocian para formar tejidos, que a su vez se asocian para formar órganos y finalmente sistemas de órganos. El sistema respiratorio está compuesto por las vías aéreas y los pulmones. Durante el proceso de respiración se produce el intercambio gaseoso de oxígeno (O2) y dióxido de carbono (CO2) entre los pulmones y la sangre. El oxígeno obtenido mediante la inspiración pasa de los alvéolos pulmonares a la sangre para llegar a cada célula del cuerpo, mientras que en cada expiración se elimina dióxido de carbono en el sentido inverso. La nutrición es el proceso de toma de nutrientes mediante el cual el organismo obtiene energía y materia de su ambiente. Durante este proceso, el sistema digestivo incorpora alimentos que posteriormente son descompuestos en moléculas simples conocidas como nutrientes las cuales son absorbidas para finalmente pasar a la sangre y así llegar a cada célula del cuerpo. La reproducción consiste en el mecanismo mediante el cual una especie se asegura su continuidad a través del tiempo. Los órganos reproductores masculino y femenino están encargados de producir células sexuales, es decir, gametos masculinos (espermatozoides) y gametos femeninos (óvulos) que se unen durante el proceso de fertilización para dar lugar a un cigoto que se desarrollará hasta formar un organismo adulto. Finalmente, la adaptación se refiere al mecanismo por el cual un organismo se ajusta a su ambiente. A nivel de especie, la adaptación es una consecuencia del proceso evolutivo por el cual aquellos organismos que se ajustan mejor a su ambiente tienen más chances de sobrevivir y reproducirse, teniendo por lo tanto más chances de transmitir sus genes a la siguiente generación.

What is NOT a function of the
nucleus?
A. Directs protein synthesis
B. Houses DNA
C. Functions as the powerhouse of the cell
Answer:
function as the powerhouse of cell
Explanation:
we have read the power house of cell as a mitochondria
==========================================================
Explanation:
The mitochondria is responsible for generating the cell's energy, hence the phrasing "the mitochondria is the powerhouse of the cell".
The nucleus holds the DNA, so we can rule out choice B. The DNA in turn is connected to forming the proteins. The actual protein synthesis happens in the ribosomes, but the DNA is used as a blueprint (more or less) to assemble the correct amino acids in the correct order to form the complicated protein chains. In short, the nucleus indirectly helps direct the protein synthesis, so we can rule out choice A.
¿Cómo defines a una Célula Haploide?
Answer:
La mitad de cromosomas.
Explicación:
Las células haploides se refieren a aquellas células que tienen la mitad de cromosomas. Estas células haploides se forman debido a la división celular de la meiosis. En la división celular de la meiosis, una célula madre se divide en cuatro células hijas que tienen la mitad de cromosomas. Estas células haploides están presentes en los espermatozoides de los gametos masculinos y femeninos, que se fusionaron formando células diploides que tienen el doble de cromosomas. El cigoto formado debido a la fusión de espermatozoides y óvulos son de naturaleza diploide.
