Answer and Explanation:
Petroleum and coal are fossil fuels. The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

Using the Gizmo, create four energy paths to explain how the toaster could get its energy.
Answer and Explanation:
Energy is well-defined as the capacity to do work. Heat is the kind of energy. It is transmitted from the high-temperature object to the low-temperature object. When electricity runs over a wire, energy is transferred from one end of the wire towards another end. Electricity flow in the wire by electrons. When electricity flows, the electrons collide with one another and give off heat due to collision. Less collision of electrons produce less heat, and more collision of electrons produce more heat. When the toaster wire plugged into the electricity supply, electric energy began to flow through the wire—the electric current run over a series of filaments. The filaments are thin and connected. When electric energy flows through the filaments, they glow red hot and transfer the bread. The filaments are present on both sides of the toaster. So the bread cook from both sides at a similar time.

What happens in the postsynaptic neuron when excitatory neurotransmitters bind to receptors?
Answer:
it causes the depolarization of the target cell
Explanation:
Glutamate is an excitatory amino acid neurotransmitter that binds to specific receptors on the surface of target cells and thus causes its depolarization. During glutamate-mediated depolarization, the difference in charge inside and outside the cell is lost due to the entry of sodium and calcium positive ions into the postsynaptic cell (neuron) through specific ion channels. Moreover, glutamate binding also leads to the exit of potassium ions from the cell, thereby resulting in excitation. Through this mechanism, glutamate regulates many signaling pathways, such as those involved in memory, learning, emotions, cognition, motor control, etc.

Which of the following statements is true regarding individual III-5? Select all that apply. Select all that apply. Individual III-5 is male. Individual III-5 is female. Individual III-5 is affected by the genetic condition. Individual III-5 is not affected by the genetic condition. Individual III-5 is the proband.
Answer:
III-5 is male.
Individual III-5 is affected by the genetic condition.
Individual III-5 is the proband.
Explanation:
In human pedigrees, males are represented by squares while females are represented by circles. Individuals affected by the focus trait in human pedigrees are usually shaded, those that are carriers are half-shaded, while those that are not affected at all are not shaded in any form.
Thus, from the pedigree (see the attached image), III-5 individual is a male and affected by the genetic condition in focus.
Also, III-5 individual is a proband, because a proband is an individual that is first affected by a genetic trait in a family.

What is the distinction between mitosis and meiosis?Mitosis outcomes in two nuclei might be equal to the authentic nucleus. Meiosis, on the other hand, outcomes in 4 nuclei, every having half of the variety of chromosomes of the original cell. In animals, meiosis handiest happens within the cells that deliver rise to the sex cells (gametes), i.e., the egg and the sperm.
Mitosis includes the division of frame cells, even as meiosis entails the division of sex cells. The department of a cellular takes place as soon as in mitosis however twice in meiosis. two daughter cells are produced after mitosis and cytoplasmic department, at the same time as 4 daughter cells are produced after meiosis.
Mitosis includes one degree whereas meiosis consists of ranges. Mitosis produces diploid cells (forty-six chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two same daughter cells whereas meiosis produces four genetically exclusive daughter cells.

During which part of meiosis (meiosis I or meiosis II) do the two alleles of a gene separate? During which phase does the separation occur? (Assume no recombination.)
Answer:
meiosis 1, anaphase
Explanation:
Meiosis is a type of cell division that consists of two rounds of cell division known as Meiosis I and Meiosis II, and one round of DNA replication, thereby the resulting cells (gametes) contain half of the genetic material found in somatic (body) cells. Both Meiosis I and Meiosis II can be divided into the following phases: Prophase, Metaphase, Anaphase, Telophase and Cytokinesis. Alleles of a gene separate during the anaphase of Meiosis I (i.e., Anaphase I), because homologous chromosome pairs separate during this phase of the cell cycle.
Answer:
During the ANAPHASE of MEIOSIS I, IF there is no recombination, the two alleles of a gene separate
Explanation:
Meiosis is a process by which, from a diploid germ cell (2n), four daughter cells with a haploid chromosome number (n) are produced. Each daughter cell has half of the chromosomes of the original one. There are two phases in meiosis: the first one in which occurs a chromosome´s reduction division, and the second one where the cell suffers a new division, but this one is not a reductive one.
If there is no recombination or crossing-over between a locus and the centromere, during anaphase of meiosis I, occurs the separation of the alleles. One of the alleles migrate to one pole and the other migrates to the other pole .But if it occurs crossing-over, the allele separation occurs in the anaphase of meiosis II, when chromatids separate.mammals reproduce using sexual reproduction. It takes two parents to produce an offspring. What can you infer about the number of chromosomes in each reproductive cell?

m. blood
n. esophagus
Answer:
Mouth -Esophagus-- Stomach -Duodenum -Jejunum -Brush border disaccharidases--Glucose transporters--Active transport--Blood-Glycolysis-Pyruvate--Citric acid cycle - Carbon dioxide and water : )
Explanation:
The journey of a glucose molecule from the mouth and ultimately to the muscle cells for energy in the correct order is:
Mouth > Esophagus > Stomach > Duodenum > Jejunum > Brush Border Disaccharidases > Blood > Glucose Transporters > Glycolysis > Pyruvate > Citric Acid Cycle > CO2 and Water > Active Transport > Electron Transport System.
The drink rich with disaccharides starts its journey from the mouth cavity and moves through the esophagus to the stomach. The disaccharide digestion takes place when it reaches the jejunum through the duodenum of the small intestine by enzyme maltase that also presents in Brush Border Disaccharidases to glucose.
Glucose moves o blood and through a glucose transporter for cellular respiration that starts with glycolysis that converts glucose to pyruvate and enters in TCA cycle and releases CO2 and water as byproducts that ultimately moves to the ETS system to provide energy to the muscles.
Thus, the correct answer is - given above in the correct order.

4) What is a zygote? How does the zygote form the organism?
A zygote is a fertilized egg cell resulting from the fusion of a sperm cell and an egg cell during sexual reproduction. It marks the beginning of a new organism's life.
After fertilization, the zygote undergoes a series of cell divisions called mitosis, where it divides into multiple cells, forming a structure known as a blastocyst.
The blastocyst then undergoes implantation in the uterus, where it develops into an embryo. As the embryo continues to grow and differentiate, it forms the various tissues, organs, and systems of the developing organism.
The zygote serves as the initial building block and contains all the genetic information necessary for the organism's development.

An example of a(n) is the brain, spinal cord, and nerves working together.
Answer:
system
Explanation:
An example of an organ system is the brain, spinal cord, and nerves working together.
A system is a level of organization in living organisms in which body organs work together to perform similar functions. The organ system represents the highest level of body organization as opposed to organ, tissue, and cell level of organization.
The cell is the smallest unit of organization of the body of living organisms. At the tissue level, cells aggregate together to perform similar functions while at the organ level, similar tissues come together to perform somewhat similar roles in the body of organisms.
The brain, spinal cord, and nerves each represent an organ. When these work together in the body of organisms, the level of organization is described as organ systems or simply systems.

Recall the Jagendorf experiment (pasted below) was conducted wholly in the dark. Hypothesize what would happen if you were to mimic the experiment, but rather than alter pH, you place your thylakoids in a beaker with a solution that mimics the chloroplast stroma in direct sunlight. What would be the result?
Answer:
ATP production.
Explanation:
The result will be the production of ATP molecules if we place thylakoids in a beaker with a solution that mimics the chloroplast stroma in direct sunlight. The thylakoids are able to formed ATP in the dark because H+ gradient is required for ATP synthesis. The scientists find out that the light reactions were not necessary to establish the H+ gradient required for ATP synthesis by ATP synthase.

Both the endocrine and nervous systems are major regulating systems of the body; However, the nervous system has been compared to an airmail delivery systtem and the endocrine system to the pony express. Briefly explain this comparison.
Answer:
The correct answer is -the nervous system is rapid whereas the endocrine is slow and effective on distant target organs.
Explanation:
Both the nervous system and endocrine system are essential and major regulating or controlling systems in an organism. The nervous system ae compared to airmail as it uses nerve stimulus to bring rapid control whereas the endocrine is like pony express as it acts much more slowly.
The nervous system is fast and rapid and required electrochemical stimulus or impulses whereas the endocrine system produces hormones and releases them to the blood which then travels to the target organ and binds to it.
