I believe it'd be on the Prime Meridian
Answer:
The correct answer is on the prime meridian.
Explanation:
Antarctica is the southernmost continent which is one of the coldest places on the earth.
The prime meridian is an imaginary line of longitude which divides the earth in the western and eastern hemisphere. the longitude at the prime meridian is 0° with a length of 20,000 km from pole to pole.
In northern hemisphere passes through countries like the UK, France, Spain and many others but in the southern hemisphere, it passes through only Antarctica continent.
Thus, option on the prime meridian is the correct answer.
What is the best definition of directional selection
Directional selection is a mode of natural selection an extreme phenotype is favored over other phenotypes this causes the allele to shift over time in the direction of the favored phenotype
Directional selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of the favored phenotype.
How do we explain?Phenotype: The observable physical characteristics of an organism.
Genotype: The genetic makeup of an organism.
Allele: A variant of a gene.
Allele frequency: The proportion of a population that has a particular allele.
In directional selection, there is a selective pressure for one extreme phenotype over the other phenotypes. This could be due to a change in the environment, such as a change in climate, or it could be due to a new mutation that gives the organism an advantage.

In a simple synapse, neurotransmitter chemicals are received by___
Mostly by Acetylcholine receptors if it is a simple neuron.
If Acetylcholine isn´t your Neurotransmitter just put the name of it before the word "receptor"
Neurotransmitter chemicals released by the presynaptic cell in a simple synapse are received by the receptors on the postsynaptic cell. Once bound, they trigger an electrical impulse in the postsynaptic cell. After transmission, the neurotransmitter is either degraded or reabsorbed for future use.
Explanation:In a simple synapse, neurotransmitter chemicals are received by the receptors on the surface of the postsynaptic cell. This is a biological process typically observed in a chemical synapse, where the neurotransmitter released from the presynaptic cell diffuses across a very minor distance called the synaptic cleft. After traversing this gap, the neurotransmitter attaches to a receptor protein, causing a change in the electrochemical potential in the postsynaptic membrane and thereby launching the next electrical impulse.
In this process, the neurotransmitter fits into its receptor akin to a lock-and-key mechanism. This binding is a very specific biochemical event, and each neurotransmitter only binds to its relevant receptor. Following the signal transmission, the neurotransmitter is rapidly degraded or reabsorbed by the presynaptic cell. This allows for the quick recovery of the recipient nerve cell and readiness to respond to the subsequent synaptic signal.

The Venn diagram compares aerobic respiration and anaerobic respiration. Which statement should be categorized only in the aerobic section of the venn diagram?
A) occurs in the cytoplasm
B) produces water
C) we cryers no oxygen
D) is performed by yeast
Answer:
The correct answer would be B) produces water.
Aerobic respiration is a type of respiration in which oxygen is used as the final acceptor of the electrons in an electron transport chain.
It usually takes place in mitochondria of a cell except for glycolysis part which takes place in the cytoplasm.
In this respiration, carbon in glucose is oxidized to produce carbon dioxide whereas oxygen is reduced to form water.
H₂ + 1/2 O₂ →H₂O
In contrast, anaerobic respiration usually occurs in the cytoplasm and results in the formation of lactic acid or ethanol and ATP.
Answer:
Produces water should be in the only aerobic section of the diagram. Aerobic respiration end products are carbon dioxide and water. Anaerobic respiration end products are lactic acid in animals and carbon dioxide and ethanol in yeast and plants. (: AKA the answer is B
Explanation:
The _______ _______ is a cavity in the crust that feeds material to a volcano.
Answer: - Magma chamber.
Explanation:-
1. A magma chamber is a cavity which acts a reservoir of magma and it feeds a volcano.
2.A magma is basically a mixture of molten and semi molten rocks.
3. The magma is less dense than the layers of rocks and as a result of this it tends to move upwards towards the surface of the earth but when it encounters a layer of rocks in this upward journey that hinders its movement then it gets collected in a large pool which is known as the magma chamber.
4. These magma chambers are under a great pressure which results in the breaking of the rock which surrounds the magma chamber with time. Once, these rocks break the magma can then travel upwards and this results in volcanic eruption.
Thus, these magma chambers are the cavities containing the magma that feeds the volcano.

In a plant called jimsonweed, flowers can be white or purple. A jimsonweed plant with white flowers is crossed with a jimsonweed plant with purple flowers. All of the offspring have purple flowers.Based on the results of the cross, which of the following statements most likely describes the alleles for flower color in jimsonweed?
Answer:
Although statements are not given in the question, we could make the most possible deduction as follows:
The allele for purple flowers is dominant whereas allele for white flowers is recessive.
Explanation:
According to the question,
Purple flower plant was crossed with white flower plant.All offsprings have purple flowers.Here we have one possibility that both parents were homozygous but in their own traits. Purple flower plants were "PP" and white flower plants were "pp" So, the first progeny (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.
what are the chances that a cross between a black chicken and white chicken will result in blue offspring?
a) 0%
b) 25%
c) 50%
d) 100%
the chances that a cross between a black chicken and white chicken will result in blue offspring is 100%, because Back and white are both incomplete dominant traits, 100% of the offspring will be heterozygous blue.
What is trait ?Traits are the attributes of an organism which are influenced by the environment and expressed by genes, the Physical features of an organism, such as hair color, leaf form, size, behavioral characteristics,
They have specific traits which allow them to be successful in the ecosystem, these are physical characteristics which include fin length, body shape, color patterns, eyesight, and muscle definition.

Each of these organs is part of a different human body system. Which organ helps in the removal of waste as part of the human excretory system? A) heart B) brain C) stomach D) bladder
The urinary system is the main excretory system of the body after the gastrointestinal tract (large intestine) and lungs, In these questions it is necessary to prioritize the urinary tract.
Where does the bladder belongs?The bladder belongs to the urinary excretory system.The bladder receives the urine produced by the kidneys via the ureter and has the function of storing it before its elimination during urination through the urethra. The muscles surrounding the bladder help to prevent urine reflux to the ureter.
The main purpose of the renal excretory system is to eliminate nitrogenous wastes while maintaining homeostasis, all through the formation of urine.
The kidney has a secretory function (filtration of blood in the glomeruli) and excretory from the pyelon (triangle based on the renal hilum) origin of the ureter. We speak of pyelo-ureteral junction. Each kidney contains about 1 million nephron.
Therefore, The urinary system is the main excretory system of the body after the gastrointestinal tract.

A student observed the butterfly in the photograph below. What is the best way for the student to identify the kind of butterfly it is?
Use dichotomous key of butterflies found in the region
* Apex
Final answer:
To identify a type of butterfly, observe physical characteristics like wing patterns and coloration, compare them to recognizable features in field guides or databases, and note their behavior and regional occurrence.
Explanation:
The best way for a student to identify a type of butterfly in a photograph is to closely observe the physical characteristics of the butterfly, such as wing patterns, coloration, and shape. While observing, they can compare these features to a field guide or online database specifically for butterflies. Since certain butterfly species may look alike due to mimicry, it's critical to note subtle differences. For instance, in the case of the monarch and viceroy butterflies, one can distinguish them by carefully examining the patterns on their wings. The monarch butterfly traditionally has larger wings and a more bold and solid color pattern compared to the viceroy, which usually displays an extra black line across its hind wings.
For a comprehensive identification, the researcher may also consider the behavior of the butterfly, such as its flight patterns and the types of flowers it visits. In addition, they can look into region-specific databases because certain species are endemic to specific areas. For butterflies that are more difficult to identify or are very similar to others, consulting with a lepidopterist or entomologist could provide expert insight.
Which of these choices is product of mitosis?
a.egg
b.sperm
c.sex cell
d.skin call
it should be the egg and the sperm.
The skin cells go through mitosis to replace dead ones. The correct answer is d. skin cells.
What is cell division?Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body. The cell division process known as meiosis is what produces egg and sperm cells. A vital process for life is mitosis.
Cell division always involves a complex set of stages that are carefully choreographed and highly controlled. While mitosis and meiosis refer to two distinct processes of nuclear division, cytokinesis describes the division of a cell's cytoplasm.
The original nucleus divides into two identical nuclei during mitosis. Contrarily, meiosis produces four nuclei, each of which has half as many chromosomes as the parent cell. Only the gametes, or cells that develop into sex, the egg, and the sperm, go through meiosis in animals.
Therefore the correct answer is d). skin cells.
