A dominant allele masks/hides the effect of a recessive allele.
Answer: True
Explanation: If you have a dominant allele it will show in the phenotype of the organism. To show a recessive allele you need a recessive pair consisting of only recessive alleles

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

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

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

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.

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.

¿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.

2.three sand dunes and a cup of water
3.three saguaro cacti, five roadrunners, and two rattlesnakes
Answer:
The correct answer is - 3. three saguaro cacti, five roadrunners, and two rattlesnakes.
Explanation:
A community is a group of interacting populations, in a particular ecosystem, of different species. The group of the same species is known as the population of the ecosystem. In the desert ecosystem, there should be a different group of populations should be found that interact with one other.
Among the given options, the third list has a different kind of species present three saguaro cacti, five roadrunners, and two rattlesnakes interact with one other and depend on one other for food and energy.
One biotic factor that affects consumers in an ocean ecosystem is...

O number of autotrophs
O temperature variation
O pH of water
One biotic factor that affects consumers in an ocean ecosystem is Salt content.
What are Salt content?The mother and fetus undergo a change throughout the second trimester. Typically, you'll start feeling better and displaying the pregnancy more.
The fetus has completed the development of all of its organs and systems and is about to start expanding in size.
The umbilical cord continues to thicken as it supplies the fetus with nutrients during the second trimester. However, dangerous substances can also transfer from the mother to the fetus through the umbilical cord, so caution should be taken to stay away from known dangers like alcohol and tobacco.

How is cytokinesis different
in plants and animals
Answer:
MAIN DIFFERENCES
- During cytokinesis, animal cells undergo a narrowing in the center, which does not occur in plant cells.
- Once the process is finished, the plant cells are partially united while in the case of animals they remain separated.
- A fundamental difference is that in animals, cytogenesis occurs by strangulation, but this is not the case of plants, which is by septation.
Explanation:
