Ammonia (NH3)can be products by bacteria in the soil by two processes:
What. And. What
Answer: Ammonification and nitrogen fixation.
Explanation:
Ammonification is the process where by organic nitrogen is converted ammonia in the soil by bacteria. These occur when bacteria breakdown the remains of dead plants and animals to release organic nitrogen and it is converted to ammonia.
Nitrogen fixation it is the process where atmospheric nitrogen is converted to ammonia or nitrate in the soil, in a way it is absorbed by plants. It is fixed by bacteria in root nodules of leguminous plants or by lightening.

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 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.

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 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.

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.

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

How is mitochondrial DNA (mtDNA) typing used in forensic science?
Answer:
Mitochondrial DNA typing is a method used by forensic scientists which match the DNA of unknown sample to the sample collected from the crime scene.
This typing method posses several advantages over other nuclear DNA typing methods in forensic science as:
A large copy number of DNA (2-10 times) per mitochondria provide enough DNA sample. Depending on the functions, a cell can have many mitochondria (1-100) which can provide enough sample for typing. No recombination takes place in mitochondrial DNA so DNA sample remains unchanged over many generations. So, the sample can be matched easily with the relatives of the unknown sample. Mitochondria show only maternal inheritance that they take DNA from mitochondria of the mother. DNA is amplified using Polymerase chain reaction which undergoes direct sequencing.Thus, mitochondrial DNA typing has several advantages in forensic science.
Mitochondrial DNA (mtDNA) typing is a valuable tool used in forensic science for identifying individuals and establishing maternal relationships.
what is nuclear DNA?Unlike nuclear DNA, which is inherited from both parents and is unique to each individual (except for identical twins), mtDNA is inherited solely from the mother and is passed down unchanged from generation to generation. This unique inheritance pattern makes mtDNA analysis particularly useful in certain forensic scenarios.
In cases where human remains are found and conventional methods of identification, such as fingerprinting or dental records, are not feasible, mtDNA analysis can be used to identify the deceased.

The island’s ecosystem will recover due to primary succession.
The island will lose all of the plant and animal populations of the island.
The island will suffer a loss of native plant and animal species.
Answer:
The most appropriate option would be: The island will suffer a loss of native plant and animal species
Explanation:
A hurricane is a calamity that manifests itself in the form of great rain fall, strong winds and thunderstorm.
Hurricanes just like all other natural calamities cause a lot of destruction to the organisms living in an area, their habitats and become a source of introduction of certain invasive species.
If a Hurricance hits a small island in the Caribbean, there are a lot of chances that Island will lose a large amount of animals and plant species. The fact is that when a hurricane hits and goes, many not all specie re-emerge eco-system establishes due to process of succession. However, there are some native plant and animal specie that are native to a specific place like that Island, so there are more chances that after that large hurricane island will suffer a loss of native plant and animal species.
The climate of the Island will not be in a position to sustain the survival of all living organisms, therefore, some may starve and perish for always although some may recover too. Therefore, Option D seems best.
