Answer:
B) amino acids, protein
Explanation:
Most enzymes are chains of amino acids, this means that eventually this will form protein, enzymes are the molecules in charge of catalyzing biochemichal process in living beings, enzymes are in charge of setting in motion, slowing down or speeding up biochemical processes, they are basically in charge of finding the correct timing for the biochemical processes that happen in all the biological processes.
Explain how the reduction in dopaminergic signaling that could precede the development of motor symptoms in pd could explain the "parkinsonian personality
People with Parkinson’s disease often times develop certain personality characteristics which can be linked to the reduction of dopamine transmitters in their nervous system. This causes problems in motor movements. As a result, this group of people commonly have traits such as being passive, rigid, orderly, persistent and novelty-seeking.
Personalities who are suffering from Parkinson’s disease usually exhibit specific character traits which can be associated with the loss of dopamine transmitters in their neurotic system. Such a loss creates problems in movements of the motor. In short such people generally have features like remaining submissive, firm, arranged, determined and originality-seeking.
A(n) _______ is a muscle whose contraction is chiefly responsible for producing a particular movement.
Final answer:
The muscle primarily responsible for a particular movement is known as the prime mover or agonist. The biceps brachii is an example of a prime mover in the action of lifting a cup, with the brachialis as a synergist.
Explanation:
A muscle whose contraction is chiefly responsible for producing a particular movement is called a prime mover or agonist. Skeletal muscle is a voluntary, striated muscle type that is attached to the bones of the skeleton and facilitates body movements. Muscle tissue is capable of contracting and generating tension in response to stimulation, and its action is achieved by the coordinated effort of several muscles. While the prime mover is the principal muscle causing a specific movement, others, called synergists, may assist in the motion. Additionally, a muscle that acts with the opposite effect of the prime mover is known as an antagonist, whereas a synergist that stabilizes the origin site is termed a fixator. To illustrate, when lifting a cup, the biceps brachii acts as the prime mover, while the brachialis acts as a synergist aiding in this movement.

Describe how viruses, eukaryotic cells, and prokaryotic cells are related in terms of size.
Viruses are the smallest structures and cannot be seen through a light microscope. Prokaryotic cells are larger, averaging 1 - 5 micrometers, and do not have a nucleus. Eukaryotic cells are the largest, averaging 10 - 100 micrometers, and have a nucleus and other organelles enclosed within membranes.
Explanation:In cellular biology, viruses, eukaryotic cells, and prokaryotic cells are all structures that can contain genetic material, but they differ significantly in terms of size. Viruses are the smallest of the three, typically ranging from about 20 to 300 nanometers in diameter, and are so small that they can't be seen through a light microscope.
Prokaryotic cells, such as bacteria, are larger, generally ranging from 1 - 5 micrometers. They lack a nucleus, and their genetic material is not enclosed within a membrane.
Eukaryotic cells, like those found in humans and plants, are the largest, with a typical diameter ranging from 10 - 100 micrometers. They contain a nucleus and various other organelles all enclosed within membranes.

Second-generation antipsychotic drugs bind to dopamine receptors and _____ receptors
I believe the correct answer is serotonin
Explanation:Antipsychotic drugs are use to treat psychosis brought by any psychotic disorder for example the condition called schizophrenia. They can also be used to treat manic episodes of Bipolar disorder. The antipsychotics are divided into first-generation antipsychotics and second-generation antipsychotics with different outcomes.
Further Explanation:Second-generation antipsychotics are also known as atypical antipsychotics but with minimal side effects and they have some efficacy that is almost the same to the first generation antipsychotics. The second generation antipsychotics bind antagonistically to the dopamine D2 receptors and also bind to serotonin 5HT2 receptors. They have more affinity to these 5HT2 receptors than the dopamine D2 receptors and this is the reason why they have less side effects compared to the first-generation antipsychotics. Binding antagonistically to the receptors will help reduce the symptoms and the intensity of the extrapyramidal symptoms that are experienced. Examples of second generation antipsychotics include Asenapine, Clozapine, Lurasidone, Risperidone and Olanzapine. Clozapine is the most common drug in this category and binds weakly to the dopamine D2 receptors and more strongly to the serotonin 5-HT2 receptors. It has a half life of 12 hours. Due to these drugs binding to the alpha 1, alpha 2 and H1 receptors, they bring about side effects such as postural hypotension. Others such as risperidone cause high levels of prolactin that may cause galactorrhea. Use of these second generation antipsychotics predisposes elderly users to increased risk of stroke. All side effects include seizures in overdoses, sedation, urinary retention, postural hypotension, sexual dysfunction due to the hypotension that affects erection, cardiac arrhythmias and in fatal instances myocardial infarction, dry mouth and extrapyramidal symptoms that are similar to Parkinson's i.e. rigidity, bradykinesia and tremors that start a few weeks after the start of dosages for these drugs. Weight loss is miscellaneous and is not so common to users.

Why do trees require so much more moisture than grass?
A patient asks the nurse, "may i ask you a question?" this is an example of:
a. an open-ended question
b. a reflective question
c. a double-barreled question
d. a closed question
yes or no
Explanation:
A patient asking the nurse is he/she can ask a question provides an example of: (d) a closed question.
A closed question is a type of question that can typically be answered with a simple "yes" or "no" or with a specific factual response. In this scenario, the patient asks if they can ask a question, which can be answered with a simple "yes" or "no." It does not invite a more detailed or open-ended response.
An open-ended question is one that encourages the person to provide a more detailed or thoughtful response. A reflective question is a type of question that encourages the person to reflect on their thoughts or feelings. A double-barreled question is a question that combines multiple questions or ideas into one, making it difficult for the respondent to answer each part separately.

Answer:
a. growth of organisms
c. repair of damaged cells
d. reproduction of new cells
Explanation:
edg 2022
The cell cycle is critical for the growth, creation, repair, and reproduction of cells in organisms, ensuring genetic continuity and regulated development. The cycle includes specific phases for DNA replication and cell division, crucial for organism development and maintenance.
Explanation:The importance of the cell cycle for organisms is multifaceted and includes several critical biological processes such as the growth of organisms, the creation of new organisms, the repair of damaged cells, and the reproduction of new cells. This complex series of events ensures the continuity of life from one generation to the next. During the cell cycle, genomic DNA is replicated, allowing each new cell to have a complete set of genetic instructions. This cycle is composed of phases which include growth (G1), DNA synthesis (S phase), further growth and preparation for division (G2), and the actual division process (mitosis or meiosis).
All multicellular organisms rely on cell division for growth and, in many cases, the maintenance and repair of cells and tissues. This same fundamental process is also used by single-celled organisms as their method of reproduction. The mechanisms involved are highly regulated to prevent errors that can have severe consequences, such as cancer.
For example, transgenic ____________ can be used to make pharmaceutical products such as insulin for the treatment of diabetes and vaccines for viruses.
Final answer:
Transgenic bacteria are used to produce human insulin for diabetes treatment, created through recombinant DNA technology which allows the production of human proteins in bacterial cells, reducing cost and allergy risk. This biotechnology also extends to creating transgenic plants with enhanced agricultural characteristics.
Explanation:
For example, transgenic bacteria can be used to make pharmaceutical products such as insulin for the treatment of diabetes and vaccines for viruses. One well-known application of this technology is the production of human insulin by E. coli. Originally, insulin used to treat diabetes was derived from animals, which caused allergic reactions in some patients. The introduction of the human insulin gene into bacteria created a system where they could produce human insulin en masse, which is both more cost-effective and reduces allergic reactions compared to its animal-derived counterpart. Recombinant DNA technology has not only revolutionized the production of insulin but also other medicines such as human growth hormone, clotting factors, and fertility drugs. Furthermore, this technology is not limited to medical products; it has also been applied in agriculture to create transgenic plants with improved traits, such as pest resistance or higher yield.

n peas, yellow seed color (Y) is dominant to green seed color (y). A homozygous green pea plant is crossed with a heterozygous yellow pea plant. What is the predicted phenotypic ratio of the offspring?
The predicted phenotypic ratio of offspring from crossing a homozygous green pea plant with a heterozygous yellow pea plant is 1:1, resulting in 50% yellow and 50% green pea plants.
Explanation:When a homozygous green pea plant (yy) is crossed with a heterozygous yellow pea plant (Yy), the predicted phenotypic ratio of the offspring can be determined by using a Punnett square analysis. The genotype of the green plant can only produce gametes with the recessive allele (y), while the yellow plant can produce gametes with either the dominant (Y) or the recessive allele (y). The Punnett square analysis would show that there is a 1:1 ratio of yellow to green phenotypes among the offspring since the heterozygous parent can pass on the dominant yellow allele (Y) with a probability of 50%, leading to yellow offspring, or the recessive green allele (y) also with a probability of 50%, leading to green offspring.
Final answer:
The predicted phenotypic ratio of offspring from a cross between a homozygous green pea plant and a heterozygous yellow pea plant is 50% yellow and 50% green seeds, as per Mendelian genetics and Punnett square analysis.
Explanation:
Predicted Phenotypic Ratio in Pea Plants
When a homozygous green pea plant (yy) is crossed with a heterozygous yellow pea plant (Yy), the predicted phenotypic ratio of the offspring would involve yellow and green seeds. In this cross, each parent contributes one allele for the seed color trait. The Punnett square analysis of this monohybrid cross reveals that the offspring will have a 1:1 ratio of yellow to green seeds since yellow (Y) is dominant over green (y). Half of the offspring will inherit a Y allele from the yellow parent and a y allele from the green parent, resulting in a yellow phenotype (Yy), and the other half will receive a recessive y allele from each parent, resulting in a green phenotype (yy).
The phenotypic ratio for this cross is therefore 50% yellow and 50% green seeds. This demonstrates a classic Mendelian inheritance pattern where a single trait is controlled by two alleles with one being dominant over the other.

The clavicle can break when catching a fall with outstretched hands. describe how the impact
Final answer:
The clavicle or collarbone is vulnerable to fractures during a fall onto outstretched arms, as the force travels up the limbs to the clavicle, potentially causing it to break. This bone is crucial as it connects the sternum and scapula, but luckily, important blood vessels and nerves are not usually harmed when it fractures.
Explanation:
The clavicle, commonly known as the collarbone, is prone to fractures especially when a person falls and lands on their outstretched hands. Such a fall transmits the force of the impact through the arms to the clavicles, which may break if subjected to excessive force. The clavicle serves as an anchor, connecting the sternum and the scapula (shoulder blade), and positioning the arms on the body.
When a clavicle fracture occurs, the bone typically breaks in the middle or lateral parts due to the sternoclavicular joint being robust and not easily dislocated. Muscles surrounding the shoulder can pull the broken fragments of the clavicle in different directions, causing them to override each other. Despite being positioned over crucial blood vessels and nerves, a fracture in the clavicle rarely affects these underlying structures because the bone typically displaces anteriorly when broken.
