________________ best summarizes how Durkheim's approach to religion differed from that taken by Wallace.
Answer:
Durkheim underscored the common, public, and all-encompassing nature of religion. It also speaks to the definitions that it embodies and how it causes people to emote.
Explanation:
Durkheim is a sociologist of french origins who believed that society was more powerful than the individual.
This according to him, was so because society is held together by ideas that resonate across more than one individual. These ideas show up like norms, beliefs, and values which are subscribed to by many thus creating a collective consciousness. This collective consciousness makes it easy to predict how people generally are likely to behave either as a people or an individual.

The false spider mite, Brevipalpus phoenicis, has only two chromosomes. Which of the following pieces of evidence would allow you to determine that this animal is haploid, n=2, and not diploid, 2n=2?
a. If these two mite chromosomes have different genes at different loci.
b. If the somatic cells in these mites undergo mitosis.
c. If these two chromosomes in the mite form tetrads during prophase I.
d. If this mite produces gametes containing only one chromosome each.
Answer:
The correct answer is - a. If these two mite chromosomes have different genes at different loci.
Explanation:
If it is 2n= 2, it means that it is diploid and has two sets of chromosomes in which one set comes from mother and the other from father which means parent's genes contribute to diploid equally. Both sets of chromosomes form homologous chromosome pair. Each homolog of the pair has the same gene at the same loci in diploid and if it has not the same homologous gene at the same loci these are haploid.

The extinction vortex represents the idea that even if an organism is extant, it may have a gene pool that will not support its long-term survival.A. TrueB. False
Answer:
True.
Explanation:
Extinction vortex is a model used by scientists to understand extinction dynamics within a community. This model allows scientists to assess and understand how a population can become highly vulnerable to elements of its habitat, becoming increasingly apt for extinction. According to this model, any organism is capable of extinction, as all are susceptible to having a gene pool that will not allow its survival, regardless of the environment.
Which of the following requires constant agonist-antagonist muscle contractions?
Core integration
Postural development
Dynamic balance
Neuromuscular strength
Answer:
Postural development
Explanation:
The agonist muscles are sets of muscles responsible for causing joint motion, whereas antagonist muscles are muscles that directly opposite agonist muscles (i.e., antagonist muscles generate an opposing joint torque to the agonist muscles). In a given movement, agonist muscles exhibit concentric contractions while antagonist muscles show eccentric contractions in order to stabilize the joint. Postural development is achieved by concerted adjustments of dorsal muscles and ventral muscles. The dorsal muscles are activated when the body sways forward and the muscle fascicles shorten. During backward sway, these muscles lengthen, while ventral muscles are primarily activated.
Dynamic balance is the condition that requires constant agonist-antagonist muscle contractions.
The agonist-antagonist muscle contraction is the movement where one muscle contracts while the other muscle is relaxing or lengthening. The muscle contracts are agonist whereas the muscle that relaxes is the antagonist here.
Core integration: In such conditions, the constant movement of muscle contraction and relaxation does not require. It is a specific movement and increased stability of the movements.Postural development: continuous development and growth of postural muscles comprising the nervous systemDynamic balance: It would be the ability to balance in motion or changing positions. In this case, muscles require constant both agonist and antagonist contractionsNeuromuscular strength: motor commands according to the central nervous system to the ability to move in the nervous system, hence it does not require constant muscle movements.Thus, the correct answer is - Dynamic balance.

130 and 14C are isotopes of 12C, which has 6 electrons, 6 protons, and 6 neutrons. What is the arrangement of subatomic particles in 14c?
A. 6 electrons, 7 protons, and 6 neutrons.
The correct answer is C. 6 electrons, 6 protons, and 8 neutrons.
Explanation
An isotope is a type of atom that is characterized by having a nucleus with a different number of neutrons. Additionally, isotope atoms are those that have the same number of protons in the nucleus (in the case of carbon 6 protons), but different mass numbers. In the case of the isotope of carbon, it has 8 neutrons (2 more neutrons than the regular carbon) and 6 protons in the nucleus, that is, that its mass is 14 (6 protons + 8 neutrons equals 14). According to the above, the correct answer is C.
g 33. Humans are bipedal omnivores (we eat both meat and plants, and we walk upright.) What features of the skull reflect this
Answer:
Since Skull is the most complete fossil, the features of the skull that reflects Humans as bipedal omnivores are: The teeth and the foramen magnum.
Explanation:
Humans are bipedal because they can move with their two legs, and they are omnivores because of their ability to eat both meat and plants.
The teeth on a skull are the most important indicators of what an animal eats, and it even shows if an animal is a predator or prey. Humans have different sets and shapes of teeth for different purposes making them an example of heterodont dentition.
The pelvis, knee, and foot bones should be the best to tell us about how an animal moves, however, the foramen magnum which opens for the spinal cord to pass to the brain, could also show whether how the animal moved.

The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of
Answer:
The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.
Explanation:
Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.
In 1985 a biologist counted 750 pine trees in a 250 hectare forest. Using similar counting techniques, the biologist counted 1,250 pine trees in 1990 and 1,500 pines in 1995.
What was the average change of the size of the population from 1985 to 1995?
What was the density of pine trees each year that they were counted?
What was the average change of density from 1985 to 1995?
Answer:
Suppose that we have a given function f(x)
The average rate of change of the function between two values x₁ and x₂ is given by:
[tex]r = \frac{f(x_2) - f(x_1)}{x_2 - x_1}[/tex]
a) We want to find the average (rate) of change on the size of population from 1985 to 1995.
We have that:
f(1985) = 750
f(1995) = 1500
Then we have:
[tex]r = \frac{1500 - 750}{1995 - 1985} = 750/10 = 75[/tex]
This means that the population of trees increases, in average, at a rate of 75 trees per year.
b) What is the density of trees each year that they were counted?
This will be equal to the quotient between the number of trees and the area.
1985: number of trees = 750 pines
area = 250 ha
Then the density is:
D(1985) = (750 pines)/(250 ha) = 3 pines/ha
So 1985, there were 3 pines per hectare.
1990: number of trees = 1250 pines
area = 250 ha
Then the density is:
D(1990) = (1250 pines)/(250 ha) = 5 pines/ha
1995: number of trees = 1500 pines
area = 250 ha
The density is:
D(1995) = (1500 pines)/(250 ha) = 6 pines/ha
3) now we want to get the average change between 1985 and 1995 in the density, this will be:
[tex]r = \frac{D(1995) - D(1885)}{1995 - 1985} = \frac{6 pines/ha - 3pines/ha}{10} = 0.3 pines/ha[/tex]
So, on average, each year the number of pines per hectare increases by 0.3
assertion: empty milk pouches are biodegradable Reason: they cannot be used in biogas formation
Answer:
The pollutants like heavy metals, organic solvents present in pesticides exist in small amounts in the atmosphere. During the process of the food chain, the concentration of these pollutants progressively keeps on increasing through different trophic levels. For example, fish eats a lot of planktonic growth may retain the pollutants in their tissues, birds or people that eat the fish might concentrate the pollutants still more. This process of accumulation of pollutants at different trophic levels is called as biomagnification. So, the correct answer is 'Assertion is correct but Reason is incorrect'.
