From food to food, as the percent by mass of proteins increased, the mass of food remaining at 28 hr: 1 point A. increased only. B. decreased only. C. increased and then decreased. D. decreased and then increased.
Answer:
B. decreased only
Explanation:
If you look at the table 1 and order the foods by the percent of protein, and after you take a look at the graph, you'll see that the bigger the percentage of protein, less food remains.

cancer
Alzheimer's disease
emphysema
coronary disease
According to Friedman and Roenman study, high levels of stress are linked to Coronary heart diseases (CHD). Thus, the correct option is D.
What was Friedman and Roenman theory?
Friedman and Rosenman in the year 1976 conduced a research to show that people with type A personality run a higher risk of heart disease and high blood pressure than type Bs. Type A personality is ambitious, competitive, and aggressive while type B personalities may be patient, flexible, and laid-back.
Through their study, they remarked that the primary risk factors of Coronary Heart diseases (CHD), i.e. hypertension, smoking, and elevated serum cholesterol were found at a higher level in the people with personality A than that of personality B.
Therefore, the correct option is D.

During a baseball game, a hitter strikes the ball with a bat. When this happens, the ball and the bat exert a
force on each other. Why does the ball accelerate away from the bat more than the bat accelerates away from
the ball?
Answer:
The ball has greater velocity before the collision, so the force affects the ball more than it affects the bat. The ball has less mass, so the equal force on the ball and the bat causes greater acceleration of the ball. The bat exerts more force than the ball because the batter is exerting a force on the bat as it hits the ball

Which population eats kelp the most?
Answer:
bristle worms
Explanation:
In kelp forests, the most commonly found invertebrates are bristle worms, scud, prawn, snails, and brittle stars. These animals feed on the holdfasts that keep kelp anchored to the bottom of the ocean and algae that are abundant in kelp forests. Sea urchins will often completely remove kelp plants by eating through their holdfasts. Other invertebrates found in kelp forests are sea stars, anemones, crabs, and jellyfish.

Use the following information to answer the questions below. Skin color in a certain species of fish is inherited via a single gene with four different alleles. One fish of this type has alleles 1 and 3 (S1S3) and its mate has alleles 2 and 4 (S2S4). If each allele confers a unit of color darkness such that S1 has one unit, S2 has two units, and so on, then what proportion of their offspring would be expected to have five units of color
Answer:
1/2 = 50% of the progeny is expected to have 5 units of color → S1S4 + S2S3
Explanation:
Available data:
Single gene with four different alleles → S1, S2, S3, S4Each allele confers a unit of color darknessS1 one unitS2 two unitsS3 three unitsS4 four unitsCross:
Parentals) S1S3 x S2S4
Gametes) S1 S3 S2 S4
F1) 1/4 = 25% of the progeny is expected to be S1S2 → 3 units
1/4 = 25% of the progeny is expected to be S1S4 → 5 units
1/4 = 25% of the progeny is expected to be S2S3 → 5 units
1/4 = 25% of the progeny is expected to be S3S4 → 7 units
1/2 = 50% of the progeny is expected to have 5 units of color → 1/4 = 25% S1S4 + 1/4 = 25% S2S3

9. If you conducted the analysis portion of Experiment 2, you calculated
the rate at which the percentage of fish with a complete pelvis
decreased in that ancient lake. Do you think the same rate of change
would apply to modern fish populations?
A. Probably not, since the environment has changed so much in the 10
million years since that ancient lake existed.
B. Although we did not measure this directly, it is possible that the same
rate of change observed in the fossil record applies to modern
populations.
C. The fossil record analyzed in Experiment 2 only spans 15,000 years,
so we cannot draw any conclusions to modern populations, which
evolved over a much longer period of time, at least 10,000 years.
D. The rate of evolution of a particular phenotype cannot be calculated
from the fossil record because the fossil record is always fragmentary.
Answer: Although we did not measure this directly, it is possible that the same rate of change observed in the fossil record applies to modern populations.
Explanation:
Hi. You didn't give the experiment and I searched online but couldn't find the experiment but through further researches, I got to know that the correct option is B "Although we did not measure this directly, it is possible that the same rate of change observed in the fossil record applies to modern population"
Therefore, the correct option is B.
Which factor does NOT provide evidence of common ancestry?
a.) DNA
b.) organism size
c.) stages of early development
d.) homologous structures
The size of the organism does not provide any evidence of common ancestry. So, the correct option is B.
What do you mean by Common ancestors?Common ancestors may be defined as those characteristics of different organisms that have two or more descendants in common.
The nature and morphology of the DNA, stages, and properties of the early development of organisms, and homologous structures provide significant evidence of common ancestry between the organisms of different species.
Therefore, the correct option for this question is B.

¿Cuáles de las siguientes características permite el intercambio gaseoso entre el Oxígeno (O2) y Dióxido de carbono (CO2) en los alveolos?
Answer:
Difusión y afinidad de la hemoglobina.
Explicación:
La difusión y afinidad de la hemoglobina son las características que permiten el intercambio gaseoso entre el Oxígeno (O2) y el Dióxido de Carbono (CO2) en los alvéolos. Debido a la difusión, las células de hemoglobina descargan o eliminan el gas de dióxido de carbono que es más alto en la hemoglobina en comparación con los alvéolos, por lo que el dióxido de carbono se mueve de la hemoglobina a los alvéolos mientras que, por otro lado, el oxígeno se mueve dentro de la célula de hemoglobina a través de la difusión y la estructura de la hemoglobina atraer y adherir moléculas de oxígeno consigo mismo.
