The lower chambers of the heart are the
septum
ventricles
atrium
pacemakers
Answer:
The correct answer is - ventricles
Explanation:
A normal human heart has four chambers, two upper and two lower chambers. The upper chambers, known as the right atria and left atria that get incoming blood into the heart.
The lower chambers knowns as right ventricles and left ventricles that push the blood out of your heart to the rest of the body. Ventricles receive the blood from the atrium and pump or expel the blood to the rest of the body.
Thus, the correct answer is - ventricles.

Scientists interested in the relationship among vision, foraging for food, and fitness studied three isolated populations of a small species of primate whose diet includes small insects and fruit, both of which the animals primarily identify by sight. The three populations were once part of a larger population that was fragmented as a result of habitat destruction by humans. The study populations were selected on the basis of the significantly different vegetation among their current habitats. The scientists analyzed the frequency in each population of each of three alleles of a gene encoding an opsin protein. Opsin proteins are important for color vision, and each allele provides maximum sensitivity to a specific wavelength of visible light and thus to certain colors. Analysis of the alleles present in each population was performed in two different ways, and the data were combined to calculate the frequencies (Table 1).
Table 1. Frequency of opsin alleles in three populations of a small primate
Frequency (±2SEx¯)
Population 1 Population 2 Population 3
Allele 1 0.60 (.05) 0.80 (.06) 0.25 (.02)
Allele 2 0.15 (.02) 0.05 (.01) 0.45 (.03)
Allele 3 0.25 (.02) 0.15 (.02) 0.30 (.02)
(a) Describe one measure of evolutionary fitness.
(b) Using the template, construct an appropriately labeled graph to represent the data in Table 1. Based on the data, determine whether there is a significant difference in the frequency of EACH allele among the three primate populations.
Question 3
(c) Based on the data, identify the population that is likely to have the highest frequency of heterozygotes. Assuming random mating, calculate the frequency of animals in population 1 that carry both alleles 1 and 3.
Question 4
(d) A sudden event drastically changes the habitat of each population such that most of the normal vegetation and insects are replaced by other vegetation and insects. One of the scientists claims that population 2 will be the most severely affected. Predict the most likely effect of the event on population 2. Provide reasoning to justify your prediction.
a) Evolutionary fitness can be characterized as a person's commitment to the cutting edge's quality pool,which is chiefly founded on the aggregate or the genotype of the individual.This principally identifies with the conceptive achievement of an organic entity.
It is fundamentally determined by the offspring that can endure and pass on the characteristics/traits.
b) Graph is already uploaded in the below attached document.
c) The population 3 will have the most elevated frequency of heterozygotes,45% of the complete population.
d) Since population 2 is as of now having a low number of heterozygotes, the occasion would totally eliminate them from the population or decreases their number
Explanation:
Frequency of animals in population 1 having both alleles 1 and 3
frequency of allele 1 =0.60
frequency of allele 3= 0.25
Frequency of both allele 1 and 3 would be allele 1 + allele 3 frequency x 100
= 0.60+0.25 X 100= 85%

What changes as a front passes?
Answer:
When a front passes over an area, it means a change in the weather. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds.
Answer:
It means that a change in the weather. Front passes can cause thunderstorms, tornadoes, rain, and breezy winds.

The semester final for Mr. Garcia's science class required students to design and conduct an investigation that would answer the question "Is
styrofoam a better insulator than plastic?"
Which experiment would be most effective in helping students obtain evidence to use in answering this question?
100 mL of 70 °C water placed in 200 mL plastic cup
O A. 100 mL of 10 °C water placed in 250 mL plastic cup
wait 20 minutes, remeasure temperatures
50 mL of 70 °C water placed in 250 mL styrofoam cup
OB. 100 mL of 70 °C water placed in 250 mL plastic cup
wait 20 minutes, remeasure temperatures
100 mL of 70 °C water placed in 200 mL plastic cup
OC. 100 mL of 70°C water placed in 200 mL styrofoam cup
wait 20 minutes, remeasure temperatures
100 mL of 70°C water placed in 250 mL styrofoam cup
OD. 100 mL of 20 °C water placed in 200 mL styrofoam cup
wait 20 minutes, remeasure temperatures
100 mL of 70 °C water placed in 200 mL plastic cup
O E. 100 mL of 70 °C water placed in 250 mL styrofoam cup
wait 20 minutes, remeasure temperatures
Answer:
C
Explanation:
The correct answer is C because it puts equivalent measurements in the equivalent cup size. Both cups in answer C are the same measurement: 200 mL. The water in both cups is also the same measurement: 100 mL of 70 degrees Celsius. This is important because equivalent measurements for everything mean the experiment will be fair, equal, and accurate. If the measurements were not equal to each other, your experiment would not be as accurate.
Scientists use computer models to study complicated events and to
a. perform experiments
b. state theories
c. change theories and laws
d. make predictions
Answer:
The correct answer is - d. make predictions.
Explanation:
Computer models are scientific models that help in analyzing complex systems. Scientists use these to analyze data and on the basis of these data computer models are able to predict the outcome of the problem or can tell what will happen in the future.
These are very helpful in complex systems and are made on the basis of the data collected and are the basis of the models. Weather forecast can be predicted on the provided data.

based on the living things in the pyramid, tell me what examples would fit into these categories: primary producers, primary consumers, secondary consumers, and tertiary consumers
Answer:
- Oak trees: primary producers
- Caterpillars: primary consumers
- Blue Jays: secondary consumers
- Hawks: tertiary consumers
Explanation:
A trophic pyramid, also known as ecological pyramid or energy pyramid, is a graphic representation that shows the relationships between different types of organisms (i.e., producers and consumers) at the trophic levels of an ecosystem. The primary producers are autotrophic organisms that obtain energy from sunlight and chemical compounds from nonliving sources (e.g., photosynthetic plants, algae, etc). The primary consumers are organisms that eat primary producers (e.g., herbivores), while secondary consumers are organisms that eat primary consumers (e.g., omnivores). Moreover, tertiary consumers are predators and/or omnivores that eat secondary consumers (e.g., hawks). Finally, decomposers (e.g., bacteria) are organisms that obtain nutrients and energy by breaking down dead organic material (i.e., dead organisms) at all trophic levels into nutrients.

As a result of your Zombie Apocalypse, the grass at a local park will no longer be mowed. What type of succession is this (primary or secondary)? Describe the stages of succession that will occur in the next 100 years.
Answer:
Halloween es ese día que apenas hace unos años ni siquiera celebrábamos en España. El día de los muertos, de los monstruos y el truco o trato. Por si eres de aquéllos a los que les parece una noche inquietante, aquí estamos en Estamos Seguros para garantizarte un sueño reparador.
Si te andas preguntando si un apocalipsis zombie es posible, la respuesta es sí, pero puedes estar tranquilo: el Apocalipsis Zombie en la noche de mañana es altamente improbable. De hecho, su probabilidad es apenas del 0,00014%.
Otras veces te hemos explicado en Estamos Seguros que una prima de seguro es el resultado de multiplicar la probabilidad del percance asegurado por el capital asegurado, esto es, lo que el asegurador deberá pagar si se produce. Esto quiere decir, lógicamente, que si se conoce el capital asegurado y la prima, se puede derivar la probabilidad. Asumiendo que un posible Apocalipsis Zombie acabaría con la raza humana (o, por lo menos, con la que está asegurada), puede asumirse que un hecho así equivale a una situación tal que obligaría a las aseguradoras a indemnizar todos los capitales que tienen asegurados sobre las personas.
