38.2 mmita. 6. Draw conclusions: Between the right ventricle and the left atrium,

Explanation:

Answer:

Los alimentos son nuestro combustible y sus nutrientes proporcionan a las células del cuerpo la energía y las sustancias que necesitan para funcionar. Pero, antes de que los alimentos puedan hacer eso, los debemos digerir, descomponiéndolos en trozos pequeños para que nuestros cuerpos los puedan absorber y aprovechar.

El primer paso del proceso digestivo tiene lugar antes de que ni tan siquiera probemos la comida. Con solo oler una tarta de manzana casera o pensar en lo delicioso que va a saber un tomate maduro, empezamos a salivar, y el proceso digestivo se inicia preparándonos para ese primer bocado.

Casi todos los animales tienen un sistema digestivo en forma de tubo, donde los alimentos:

entran por la boca

pasan por un largo tubo

salen del cuerpo en forma de heces (caca) a través del ano

A lo largo del camino, se descomponen en moléculas diminutas para que el cuerpo pueda absorber los nutrientes que necesita:

Las proteínas se deben descomponer en aminoácidos.

Los almidones se descomponen en azúcares simples.

Las grasas se descomponen en ácidos grasos y glicerol.

Los residuos que el cuerpo no puede aprovechar son los que salen del cuerpo en forma de heces.

Answer:

If the average temperatures of temperate forests fell by about 25ºC during the period of 1500 years, the natural modification of the animals that would be favored would be that which allows an adaptation to the new climatic circumstances by the fauna of said forests, that is , to the notable drop in temperature. Thus, for example, animals would develop more voluminous furs, which would allow them to heat their bodies in a better way.

Answer: Measurement of the amount of waste produced.

Explanation:

Measurement of the amount of waste produced is the independent variable for a controlled experiment in this case. Therefore, the correct statement is option B.

The independent variable is the variable that can be changed in a controlled experiment. In this case, the researcher can manipulate the amount of waste produced followed by observation of its effect on the ecological footprint.

The researcher can manipulate the amount of waste by changing the factors such as the type of waste produced, recycling facilities available, etc. under controlled conditions.

Once the independent variable is manipulated, the researcher can observe its effect on the dependent variable. In this case, the ecological footprint of the individual is a dependent variable. The dependent variable is the variable that can be affected by the independent variable and is measurable.

Therefore, the measurement of the amount of waste produced is the independent variable for a controlled experiment.

Explanation:

Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.

Answer:

if the nucleotide insertion occurs within the coding region of a gene (frameshift mutation), then it will change the open reading frame (ORF) of the resulting protein and thus also will alter the phenotype of the individual  

Explanation:

A mutation is any change in the DNA sequence of the genome of a cell/organism. A point mutation is a genetic mutation where a single nucleotide is inserted, deleted or changed from the original DNA sequence. The insertion of a single nucleotide in the coding region of a gene is called frameshift mutation since this nucleotide base shifts the way the DNA sequence is read. A frameshift mutation changes the meaning of the codons that follow the inserted nucleotide base and thereby protein function is generally lost, thereby also affecting the resulting phenotype associated with this protein.

Answer:

Fire extinguisher.

Explanation:

Fire extinguisher is the appropriate safety equipment to have at the side of the baker while heating a solution in a beaker because sometimes the solution catch heat due to reactions with flammable liquids which leads to big incident so in this case fire extinguisher can avoid such type of incident by turn off the heat due to the gas present inside the container of fire extinguisher so this safety equipment is necessary at the side of the reaction.

Answer:

Nuclei of gametes and somatic cells are similar to each other in its function.

Explanation:

The conclusion of the data is that the nuclei of gametes and somatic cells are similar to each other because both performs same function in the cell i.e. regulates activities of the cell. The nuclei of somatic or skin cells work efficiently in the egg cells due to similar composition and structure of nuclei that performs similar function in the cell so that's why injection of skin cell's nuclei into egg cells results the same i.e. formation of tadpoles.

Answer:

The stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such as fire. The ultimate goal of ecological succession. After a natural disaster and continues until a climax community is reached.

Explanation:

The ultimate role of ecological succession in an environment is to reach the equilibrium in an ecosystem.

This event involve in the steady and gradual change in a species of a given area with respect to the changing environment is called as ecological succession.

The changes are inevitable process where all biotic components of the ecosystem keep up with the changes in our environment.

This process ultimately reach equilibrium in the ecosystem and the community that achieves this referred as a climax community, where some species increase in number and others decrease.

The communities that undergo changes sequentially in an area is called sere, so it is also called as seral stage or seral community.

Evolution has taken place simultaneously with that of ecological succession, so all the communities we observe are the result of ecological succession.

Answer:

The correct answer is - parasitic.

Explanation:

The Maculinea Alcon butterfly has a unique relationship with species of Myrmica ants. The butterfly's caterpillars picked up by passing Myrmica ants, and take to their nests where this caterpillar makes sounds like the queen ants, and to this sound, all ants protect and feed this caterpillar instead of other ants.

Normally there is a mutualistic relationship between ants and caterpillars but in the case of The Maculinea Alcon caterpillar and Myrmica ants, there is a parasitic relationship.

Explanation:

In humans, the blood group system is known as the ABO system where blood groups A and B are codominant and O blood group is recessive. The genotype of the A blood group could be AA or AO similarly for the B blood group genotype would be BB or BO, for the O blood group OO whereas for the AB blood group both A and B alleles should be present together.

Cross: AB blood type father with an A blood type mother (genotype AO)

Gametes: A, B and A, O

Punnett square:

       A       B

A    AA     AB

O    AO    BO

Here, there are 25% chances of AB blood group offspring 50% for the A blood group (AA and AO) and 25% B blood group (BO).

Answer:

C. a distant luminous object travels rapidly away from an observer.

Explanation:

Option C is the correct answer.

Redshift is actually observed when a distant luminous object travels rapidly away from an observer.

In redshift, observers actually see an object that is travelling away from them and it has longer wavelength. The opposite is the blueshift where observers see a light traveling towards them  and shifted to shorter wavelength.

In astronomy, redshift takes place when the object's visible light travels towards the red end of the spectrum.

A red shift is observed when a luminous object is moving rapidly away from the observer.

A red shift refers to a shift to a longer wavelength. It is observed when a luminous object is moving away from an observer. This is different from a blue shift where the luminous object is moving towards the observer.

Hence, in astronomy, a red shift is observed when a luminous object is moving rapidly away from the observer.
