Answer:
Somatic: Skeletal muscle activation VoluntaryPrincipally involved with movement "of" the body.Autonomic: Can be excitatory or inhibitory on the target organ. Principally involved with the movement of materials through the body. Intestinal smooth muscle activation. Sweat gland activation Lacrimal gland activation Piloerector muscle Involuntary activation.Explanation:
We can divide the nervous system into the central nervous system, which consists of the brain and spinal cord, and the peripheral nervous system, which consists of all the nerves that are throughout the body carrying information from and to the central nervous system.
We divide the peripheral nervous system into the somatic nervous system and the autonomic nervous system.
The somatic nervous system is the conscious one, that is to say, that we know and control what it does. It is voluntary. It has motor and sensory neurons that carry information to and from the central nervous system. The somatic nervous system is the one that makes us move our muscles to do an action.
The autonomic nervous system is involuntary. In other words, we can not control it consciously. It is the one that controls glands, organs, and smooth muscle, like the one that surrounds the digestive tract to move the food. As we can not consciously control it, this system can work exiting or inhibiting an organ depending on the situation.
The peripheral nervous system is simply divided into 2 types, which are the somatic nervous system and the autonomic nervous system.

what must be true about two objects if heat is flowing between them
Answer:
The objects must be the same temperature.
Explanation:
if heat is flowing between two objects, so both the objects must have the same temperature because the heat in object 1 passes to the object 2 due to the conduction property present in these objects. The heat flows from one body to another body until both have the same amount of heat energy as well as temperature so that's why we can say that both objects must be the same temperature.

Enter the sequence of the DNA coding strand with a 5-3 polarity. DO NOT WRITE 5 OR 3 OR 5' OR 3' IN THE BOX!
Complete question:
Use the sequence below to answer the following questions
3’-ACGGATCCTCCCTAGTGCGTAATACG-5’
5’-TGCCTAGGAGGGATCACGCATTATGC-3’
1. Enter the sequence of the coding strand with a 5’-3’ polarity
Answer:
coding strand → 5´- GCATAATGCGTGATCCCTAGGCA -3´
Explanation:
When referring to the coding strand, we are talking about the sequence that turns to be the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.
The coding strand receives that name because it is the sequence that codes for each amino acid composing the proteins.
When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.
The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.
Whenever we have a DNI molecule and we need to determine which strand is the coding one, we just need to look for the presence/absence of start or stop codons.
So, in the exposed example we have two strands, but we do not know yet which one is the coding one.
Conventionally, the first strand is always the coding one. However, let us analyze it by using the presence/absence of codons.
First-strand:
3’-ACGGATCCTCCCTAGTGCGTAATACG-5’
let us write it is 5´to 3´direction
5´- GCATAATGCGTGATCCCTAGGCA -3´
now let us identify the start and stop codons in 5´⇒3´direction.
Start codon ⇒ ATGStop codon ⇒ TAA, TAG, TGA5´- GCATAATGCGTGATCCCTAGGCA -3´ ⇒ 1 start codon at the beginning
5´- GCATAATGCGTGATCCCTAGGCA -3´ ⇒ 3 Stop codons
Second strand: We will do exactly the same procedure
5’-TGCCTAGGAGGGATCACGCATTATGC-3’⇒ 1 start codon near the end
5’-TGCCTAGGAGGGATCACGCATTATGC-3’⇒ 1 stop codon at the beginning
What we did here was to identify in both provided strands, where the start and stop codons are placed. We can see that in the first strand we have the start codon near the beginning, while in the second strand we have it near the end of the sequence. From this information, we can assume that the first strand is the coding one. However, you need to know that some coding sequences do not have start and stop sequences, because they might correspond to a sequence in the middle of a gene.
So, the sequence of the DNA coding strand with a 5-3 polarity is
5´- GCATAATGCGTGATCCCTAGGCA -3´
In pea plants, flowers are either white or purple: the purple color is produced by pigments called anthocyanins. The production of anthocyanins is a two-step process: the first step is controlled by the C gene and the second by the P gene. Both genes must produce functional proteins for anthocyanin to be produced. This is an example of:
Answer:
This is an example of gene translation.
Explanation:
Gene translation refers to the genetic process where a set of genes is used to create amino acids that will be responsible for creating a protein needed to perform some function or characteristic of the organism. In the question above, we can see that anthocyanin, responsible for the pigment of flowers, is created through the work of proteins that are created from gebes C and P. This is an example of gene translation, as it presents the formation of proteins regulated by genes.

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.

Classify the receptor descriptions or names below based on which neurotransmitter each is associated with. alpha-Adrenergic beta-Adrenergic Muscarinic Nicotinic Only receptor found in parasympathetic synapses Associated with mushroom poison Ultilizes calcium ions as a second messenger Associated with tobacco Norepinephrine Acetylcholine Reset
Answer:
1. Acetylcholine:
- Muscarinic
- Nicotinic
- Associated with mushroom poison
- Only receptor found in parasympathetic synapses
- Associated with tobacco
2. Norepinephrine:
- alpha-Adrenergic
- beta-Adrenergic
- Utilizes calcium ions as a second messenger
Explanation:
Acetylcholine (ACh) is a neurotransmitter that acts in both the central and peripheral nervous systems. Cholinergic receptors are receptors that bind to ACh. Muscarinic receptors are G protein-coupled receptors involved in the parasympathetic nervous system, which play roles in a variety of physiological responses (e.g., ACh binds to muscarinic receptors in the pathophysiology of asthma, leading to an increased mucus secretion). Nicotinic receptors bind to nicotine, while muscarinic receptors bind to muscarin (muscarine is a well-known neurotoxic alkaloid found in certain mushrooms). Nicotine receptors are also called cholinergic receptors since they also respond to ACh. On the other hand, norepinephrine (NE) binds to alpha-adrenergic and beta-adrenergic receptors in different tissues. Both alpha-adrenergic and beta-adrenergic receptors are G-protein coupled receptors. Alpha-adrenergic receptors are involved in the regulation of blood pressure and generating a sympathetic 'fight and flight response'; whereas beta-adrenergic receptors modulate sympathetic responses in the cardiovascular, metabolic, and central nervous systems (NE activates the beta1-receptor). NE can induce Ca2+ release, which is a second messenger that controls a wide variety of cellular processes.
A 45-year-old woman named Christine is measured as having the following skinfold thicknesses on the right side of her body: Triceps: 14mm; Thigh: 32mm; Suprailium: 28mm. Estimate her body fat percentage.
Answer:
The skinfold method, the measurement of subcutaneous fat folds, is the most widely adopted field method for the assessment of body fat, especially in children.
It is based on the principle that fat is of a known density and by “summing” measurements of subcutaneous fat thickness across the body, total and regional fat can be estimated.
Skinfold thickness measurements are typically used to rank individuals in terms of relative total “fatness”, or to assess subcutaneous fat at various regions of the body.
Population specific equations are used to derive estimates of percent body fat.
In infancy, it might be the sole tool available for assessing body composition longitudinally as other methods may not be feasible, or may only be suitable for use at body sizes e.g. PEA POD, can only measure infants up to 10kg.
The most generally used field method for determining body fat, particularly in kids, is the skinfold method, which involves measuring subcutaneous fat folds.
What is skinfold method?Skinfold method is defined as a method for determining how much body fat there is. It entails delicately pinching the skin and underlying fat in several locations using a tool called a caliper. To acquire precise findings using this quick and easy body fat estimation technique, a high level of competence is needed.
It is based on the idea that since subcutaneous fat thickness measurements may be "summed" to estimate total and regional fat because subcutaneous fat has a known density. Measures of skinfold thickness are widely used to categorize individuals based on their relative degrees of overall "fatness" or to assess subcutaneous fat in various bodily regions. Estimates of the percent body fat are derived using equations that are specific to a population.
Thus, the most generally used field method for determining body fat, particularly in kids, is the skinfold method, which involves measuring subcutaneous fat folds.

Describe the unique anatomical features of cardiac muscle. What role does the unique structure of cardiac muscle play in its function
Answer:
The cardiac muscle is made up of branched muscle cells, which have 1 or 2 nuclei and which the contact area between the heart fibers gives rise to specialized regions at the level of the plasma membrane called intercalary discs. The intercalary discs unite the cardiac muscle cells with each other, which provides greater adhesion to the tissue and intervenes in the rapid communication between cells. This allows its simultaneous contraction and the production of the beat.
Explanation:
The intercalary discs are the union systems that associate the cardiac muscle cells to form the myocardial fibers, the cardiac muscle is the muscle tissue of mixed components, which is located exclusively in the walls of the heart. For this reason, it has the function of generating the necessary contractions for the blood to reach all parts of the body.The intercalary discs are a special type of intercellular junction, a gap that guarantees electrical communication between these cells; and on the other hand, it provides places of adhesion and anchorage of one cell with another. The intercalary discs provide the structural foundation that allows the heart to behave as a functional syncytium.
The following statement is incorrect as stated "Pesticides create pesticide resistance in mosquitoes." Rewrite this sentence so that it is a more accurate statement of what actually occurs when pesticides are used. Why is this concept important to know in trying to control outbreaks of mosquito transmitted diseases such as eastern equine encephalitis (also known as Triple E)?
Answer:
Mosquitoes usually become resistant to pyrethroids through the mutation of a sodium channel gene that controls the movement of ions across cell membranes. Mutations in a single gene are enough to make mosquitoes almost completely resistant to the level of pyrethroids used in insecticides.
