g. hypothalamus
h. cerebrum
i. epithalamus
j. cerebrum
k. cerebellum
Explanation:
The brainstem is the posterior part of the brain that connects the cerebrum with the spinal cord. The brainstem can be divided into three parts: midbrain (i.e., mesencephalon), the pons (i.e., metencephalon), and the medulla oblongata (i.e., myelencephalon). The mesencephalon is a region of the brain composed of the tectum and tegmentum, which play fundamental roles in motor movement, auditory and visual processing. The corpora quadrigemina is found at the tectum region of the midbrain. The diencephalon is a small part of the brain located above the brainstem (between cerebral hemispheres); which contains the thalamus, hypothalamus, subthalamus, and epithalamus. In turn, the epithalamus is composed of the habenular nuclei, pineal gland, and the stria medullaris thalami. The cerebral aqueduct is a narrow channel (approx. 15 mm) in which the cerebrospinal fluid flows between the third ventricle and the fourth ventricle. The medulla oblongata is a long stem-like structure located in the brainstem of the brain, just in the place where the brainstem connects the brain to the spinal cord. The choroid plexus is a complex network of capillaries located at the cerebral ventricles of the brain, which serve to produce cerebrospinal fluid through ependymal cells that line the ventricles of the brain. The cerebellum is a major structure of the hindbrain and consists of the cerebellar cortex and a core of white matter having the cerebellar nuclei.

What trait are narcissists likely to have that is associated with leader emergence but not effectiveness
Answer:
Agreeableness.
Explanation:
Agreeableness is the trait that narcissists likely to have which is negatively corelated and is associated with leader emergence but not effectiveness. The tendency toward self-interest would attract the person into follow his or her own goals rather than the interests of their group or company. The term Narcissism originated from Greek mythology, where a young man whose name is Narcissus fell in love with his own image reflected in a pool of water so that's why selfness and self interests refers to Narcissism.
Dark skin ( a result of increased melanin production in equatorial populations), is likely a response to ultraviolet radiation because UV radiation causes:
Answer: Skin cancer
Explanation:
Melanin is a pigment derived from an amino called acid tyrosine. The most common form of melanin is called eumelanin, which is a polymer of dihydroxyindole carboxylic acids and their reduced forms. When a person is exposed to the ultraviolet light (UV) from the sun, the melanocytes will produce eumelanin to prevent the skin from burning and damage to the cell nuclei (where DNA is found) of the epidermis. This melanin production causes the skin to darken. The eumelanin in the skin then acts as a natural sunscreen by blocking the damaging effects of sunlight. So, skin darkens when exposed UV light, thus providing greater protection when needed by producing more eumelanin, but it also becomes more likely to develop melanoma, which is a type of skin cancer. This is because UV rays damage the DNA of skin cells. The DNA (deoxyribonucleic acid) is the genetic material that has the instructios to the growth and functioning of an organisms). Skin cancers begin when eumelanin protection is not sufficient and this damage affects the DNA of the genes that control the growth of skin cells. This results in a tumor, which is the uncontrolled growth of cells (in this case, skin cells) because there will be a mutation in DNA that affects the function of the cells.
The protein salmon has an isoelectric point of 12.1. Suppose you did a pH titration of a solution containing salmon. At what pH will the protein aggregate
Answer:
The correct answer is - 12.1.
Explanation:
In the case of the same isoelectric point of protein and the pH value of the solution, it is the only condition when aggregation of proteins takes place.
When there is intrinsically disordered proteins or misfolded proteins aggregates known as the protein aggregate. So for the first aggregation takes place at pH= 12.1.

In most unsaturated fatty acids found in animal fats, vegetable oils, and biological membranes, the cis isomer predominates. true false
Answer:
The correct answer is - true.
Explanation:
Most unsaturated fats are oils and normally are biological membranes or plant-based such as vegetables. These fats mostly have cis isomer in them. Unsaturated fats help to lower blood cholesterol levels.
However, few oils show saturated fats but these are few in number, the majority are made up of unsaturated fats that have double bonds.

I need help!!1
Answer:
both b and c I think..........
Population - An individual life form. and Community - A group of populations.
What is population?A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait.
A population is the group of people from which a statistical sample is taken in statistics. Therefore, a population is any collection of people who have something in common.
A statistically significant portion of a population, rather than the full population, may also be referred to as a sample. For this reason, the standard deviation, or standard error, of a statistical study of a sample from the full population must be disclosed.
Therefore, Population - An individual life form. and Community - A group of populations.

E. Oral cavity to the nasopharynx to the trachea to the right and left main bronchi.
Answer:
D. Oral cavity to the trachea to the larynx to the right and left main bronchi.
Explanation:
The respiratory system may be a system consisting of specific organs and structures used for gas exchange in animals and plants.
What is the process of respiration?We have a pair of external nostrils opening out above the upper lips. It results in a nasal chamber through the nasal passage. The nasal chamber opens into the pharynx, some of which are the common passage for food and air. The pharynx opens through the larynx region into the trachea.Trachea is a straight tube extending up to the mid-thoracic cavity, which divides at the extent of the 5th thoracic vertebra into a right and left primary bronchi. Each terminal bronchiole gives rise to a variety of very thin, irregular-walled, and vascularized bag-like structures called alveoli. The branching network of bronchi, bronchioles, and alveoli comprise the lung.
Thus, we can conclude that the correct option is (e).
The oral cavity to the nasopharynx to the trachea to the right and left main bronchi.

In this task, you’ll record the direction of a compass as it’s placed at different points around a magnet. The investigation will try to answer the question, Do two magnets create magnetic force fields that allow them to interact without touching?
Part D :
How might someone dispute the results of this investigation? How might you counter the argument?
Answer:
It could be argued that there is a separate force acting upon the investigation. Or that the room is invalidating the results for some reason. Or that an error was made in measurement.
There are a thousand and one ways to try to dispute an investigation like this. However, for every argument that can oppose it, a counterargument can easily be made.
For instance, controlling the variables invalidates about 90% of any possible claims to the contrary. The majority of arguments would stem from the fact that it is nearly impossible to completely prove something in fear of external factors. The solution? Control the external factors.
So, in conclusion, a person could dispute the results of the investigation by claiming that something invisible like magnetics could not possibly be proven to exist, because there are all sorts of things that could be influencing the investigation. The way to counter the argument would be to prove yourself that the environment is controlled, and that nothing could be influencing the investigation.

in order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many ___ bonds
Answer:
In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many hydrogen bonds
Explanation:
In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.

If the entire mRNA sequence for a polypeptide was AUGUACUCGCGACCGUAA, how many amino acids does the polypeptide have
Answer:
5 amino acids
Explanation:
The process of translation involves synthesizing a sequence of amino acids from a mRNA template. The mRNA molecule is read in a group of three nucleotides called CODONS. A codon specifies or codes for an amino acid.
In the question, a mRNA sequence was given as follows: AUGUACUCGCGACCGUAA. From this sequence comprising of 6 codons, 5 possible amino acids will be contained in the polypeptide encoded by this mRNA molecule as the last codon (UAA) is a STOP codon. The following are the codons in the mRNA sequence and their respective amino acids:
*AUG- methionine (met)
*UAC - tyrosine (Tyr)
*UCG - Serine (Ser)
*CGA - Arginine (Arg)
*CCG - Proline (Pro)
*UAA - Stop
Recall that one approach to the study of cell cycle regulation has been to fuse cultured cells that are at different stages of the cell cycle and observe the effect of the fusion on the nuclei of the fused cells (heterokaryons). When cells in Gl are fused with cells in S, the nuclei from the Gl cells begin DNA replication earlier than they would have if they had not been fused. In fusions of cells in G2 and S, however, nuclei continue their previous activities, apparently uninfluenced by the fusion. Fusions between mitotic cells and interphase cells always lead to chromatin condensation in the nonmitotic nuclei. Based on these results, identify each of the following statements about cell cycle regulation as probably true (T), probably false (F), or not possible to conclude from the data (NP). Sort each statement into the appropriate bin.
1. The transition from mitosis to G1 appears to result from the disappearance or inactivation of a cytoplasmic factor present during M-phase.
2. The activation of DNA synthesis may result from the stimulatory of one or more cytoplasmic factors.
3. Gl is not an obligatory phase of all cell cycles
4. The transition from G2 to mitosis may result from the presence in the G2 cytoplasm of one or more factors that induce chromatin formation.
5. The transition from S to G2 may result from the presence of a cytoplasmic factor that inhibits DNA synthesis.
A. T
B. F

Answer:
1. T
2. T
3. NP
4. F
5. F
Explanation:
In somatic cells, the cell cycle can be divided into 1-the interphase, 2-the mitotic phase or M phase, and 3-the G₀ phase. In turn, the interphase of the cell cycle can be divided into three phases: 1-the gap 1 (G1) phase or growth 1 phase, 2-the S phase (DNA replication or DNA synthesis), and 3-the gap 2 (G2) phase or growth 2 phase. During the G1 phase, the cell synthesizes key enzymes which are required during DNA replication (S phase) and cell division (M phase). Cytoplasmic factors are proteins and messenger RNAs (mRNAs) that control cell functions during the cell cycle. This cycle is modulated by proteins known as control factors, i.e., cyclins and cyclin-dependent kinases (Cdks) that work together to control the progression through different phases of the cell cycle. The transition from S to G2 occurs after DNA replication. This transition (S to G2) is controlled by a DNA damage checkpoint orchestrated by the ATM (Ataxia telangiectasia mutated) and ATR (Ataxia Telangiectasia and Rad3 related) kinases which are recruited to DNA damage sites. Moreover, the transition from G2 to M phase is mediated by the accumulation of mitotic inducers, which lead to an increase in the activity of mitotic kinase and finally trigger mitotic entry.
