Which of the following would indicate the closest relationship.
Two organisms in the Kingdom Animalia
Two organisms in the Phylum Cordata
Two organisms in the Genus Homo
Two organisms in Domain Eukarya
Two organisms in the Genus Homo would indicate the closest relationship.
The extant species Homo sapiens (modern humans) and several extinct species categorized as either ancestral to or closely related to modern humans (depending on the species) are all included in the otherwise extinct genus Australopithecus, where the species Homo first appeared.
The most notable of these extinct species are Homo erectus and Homo neanderthalensis. The first individual of the genus, Homo habilis, emerged just over 2 million years ago. Homo, along with the genus Paranthropus, is most likely related to Australopithecus africanus, which had previously diverged from the Pan, or chimpanzee, branch.
The scientific name of the genus Homo implies that its constituent species can be categorised as humans. Furthermore, over the course of the 20th century, fossil discoveries of early human and pre-human creatures from the late Miocene and early Pliocene produced a diverse range for classification debates.

A viral outbreak in a city needs to be traced to its source. How can wastewater be used to trace the viral outbreak?
Viral outbreak could be traced through wastewater as follows-
New viral variations could be found when they first arise in a region using wastewater surveillance.
Data from clinical tests can be supplemented by wastewater monitoring, which offers an accurate overview of the kinds and quantities of viruses and bacteria proliferating in a community. Cost-effective since a single wastewater sample provides a significant quantity of information about an entire building, town, or county.
In both untreated and treated wastewater as well as in receiving water bodies, viruses are pervasive and persistent.
Human feces, especially that from diseased people, is one of the major sources of viruses, including viral diseases, in wastewater.
Enteric viruses are discharged by sick people into sewage systems. Per gram of feces, an infected person excretes 10∧5 to 10∧12 virus particles.
It has been demonstrated that the prevalence and diversity of harmful viruses in wastewater resemble the distribution of infections among humans.

Which of the following statements is TRUE?
A. When muscles contract they become longer.
B. Involuntary muscle can be identified by its unique striped appearance.
C. The biceps and quadriceps are an antagonistic pair.
D. The origin of a muscle is attached to the bone that does NOT move.
"The origin of a muscle is attached to the bone that does NOT move" is true among the following statements.
The origin and insertion of an attachment are the points of attachment. When a muscle contracts, the point of attachment known as the origin remains stationary. As a result, when contraction occurs, the origin bone is the more immobile of the two bones at the joint.
Skeletal muscles have two or more points of attachment to bone, or occasionally to other muscles or tissues. The attachment is said to as having an origin if the location is a bone that is stationary during an action. The attachment is referred to be an insertion if the location is on the bone that moves during the motion.
The triceps brachii has four places of attachment: three origins and one insertion on the ulna (two on the humerus and one on the scapula).

Why had the US and USSR worked well together before 1945?
A. The Soviet Union had pretended to be capitalist until 1945
B. The Communists did not take over until after the war
C. When Joseph Stalin took over, the relationship changed
D. Cooperation was necessary to fight Germany and Japan
Answer: D I think
Explanation:
Before 1945, the US and USSR worked well together mainly because cooperation was necessary to fight common enemies, Germany and Japan, during World War II. Thus, correct option is D.
In order to fight Nazi Germany and Imperial Japan, the US and USSR forged an alliance during World War II. The two nations momentarily put their ideological differences aside to concentrate on the shared threat, which is how the partnership came about. During this time, both countries provided one another with military assistance and basic resources.
It is crucial to remember that the alliance began to deteriorate following the war as conflicts developed between the capitalist US and the communist Soviet Union. The Cold War, which was defined by rivalry and mistrust between the two superpowers during the post-war period, heralded a substantial change in their earlier cooperative relationship.

Within a population of butterflies, the color brown (B) is dominant over the color white (b) and 32% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam (teehee), calculate the following:
12% of butterflies in the population have homozygous dominant genetic makeup. If there were 4,216 people in the population, then there would be 48% heterozygous butterflies.
What is Hardy-Weinberg's principle?In the absence of other evolutionary factors, the Hardy-Weinberg principle asserts that allele and genotype frequencies remain constant from generation to generation.
Brown (B) outnumbers white (b) in proportion to the population's characteristics.
Recessive phenotype frequency
(Q)= 40%
Q = 0.4
According to the Hardy-Weinberg principle, the frequency is given by P and Q for a population with the dominant and recessive trait, where P+Q=1 preserves the equilibrium of the population allele.
So then, P = 1-Q
P = 1-0.4
P = 0.6
Heterozygotic butterflies = 2PQ
So, 2PQ= 2x0.6x0.4
=0.48
So, 48% of the population is heterozygous.
Homozygous dominant individual frequency = 1 - (40 + 48) = 12 i.e. 12%.

Which of the following is TRUE of the transmission of neural signals?
Signals are transmitted from the dendrites of the presynaptic neuron to the axons of the postsynaptic neuron.
Action potentials are transmitted across synapses by neurotransmitters.
Synaptic vesicles are extensions of the dendrites that receive information.
The strength of an action potential is related to the strength of incoming signals.
Explanation:
single neuron, or nerve cell, can do a lot! It can maintain a resting potential—voltage across the membrane. It can fire nerve impulses, or action potentials. And it can carry out the metabolic processes required to stay alive.
A neuron’s signaling, however, is much more exciting—no pun intended!—when we consider its interactions with other neurons. Individual neurons make connections to target neurons and stimulate or inhibit their activity, forming circuits that can process incoming information and carry out a response.
How do neurons "talk" to one another? The action happens at the synapse, the point of communication between two neurons or between a neuron and a target cell, like a muscle or a gland. At the synapse, the firing of an action potential in one neuron—the presynaptic, or sending, neuron—causes the transmission of a signal to another neuron—the postsynaptic, or receiving, neuron—making the postsynaptic neuron either more or less likely to fire its own action potential.
Schematic of synaptic transmission. An action potential travels down the axon of the pre-synaptic—sending—cell and arrives at the axon terminal. The axon terminal is adjacent to the dendrite of the post-synaptic—receiving—cell. This spot of close connection between axon and dendrite is the synapse.
Schematic of synaptic transmission. An action potential travels down the axon of the pre-synaptic—sending—cell and arrives at the axon terminal. The axon terminal is adjacent to the dendrite of the post-synaptic—receiving—cell. This spot of close connection between axon and dendrite is the synapse.
In this article, we'll take a closer look at the synapse and the mechanisms neurons use to send signals across it. To get the most out of this article, you may want to learn about neuron structure and action potentials first.
Electrical or chemical transmission?
At the end of the 19th and beginning of the 20th century, there was a lot of controversy about whether synaptic transmission was electrical or chemical.
Some people thought that signaling across a synapse involved the flow of ions directly from one neuron into another—electrical transmission.
Other people thought it depended on the release of a chemical from one neuron, causing a response in the receiving neuron—chemical transmission.
We now know that synaptic transmission can be either electrical or chemical—in some cases, both at the same synapse!
Chemical transmission is more common, and more complicated, than electrical transmission. So, let's take a look at chemical transmission first.
Overview of transmission at chemical synapses
Chemical transmission involves release of chemical messengers known as neurotransmitters. Neurotransmitters carry information from the pre-synaptic—sending—neuron to the post-synaptic—receiving—cell.
As you may remember from the article on neuron structure and function, synapses are usually formed between nerve terminals—axon terminals—on the sending neuron and the cell body or dendrites of the receiving neuron.
Schematic of synaptic transmission. An action potential travels down the axon of the presynaptic—sending—cell and arrives at multiple axon terminals branching off from the axon. The axon terminal is adjacent to the dendrite of the postsynaptic—receiving—cell. This spot of close connection between axon and dendrite is the synapse.

If the difference between the wet-bulb and the dry-bulb temperature is 4 and the dry-bulb temperature is 14, what is the dew point temperature?
The dew point temperature is 6°C when the difference between wet-bulb and dry-bulb temperatures is 4°C and the dry-bulb temperature is 14°C.
To calculate the dew point temperature, a table is used instead of a formula. To determine the dew point temperature the dry-bulb temperature (which is 14°C in this case) on the left side of the table is noted and then the difference between wet-bulb and dry-bulb temperatures, i.e. 4°C is noted given on the top of the table.
