Answer:

A. synthesis of vitamin C.

Explanation:

Integumentary system refers to the skin and its appendages. So it doesn't have the role to synthesis vitamin C, but it can synthesis  vitamin D through exposure to UV light. The major role of integumentary system is protective role (immuno defense-from infections, dehydration, temperature changes, protection of underlying tissue etc). It also contains many receptors (for pain, touch, temperature change) that detect environmental changes.

Out of the given options, Vitamin C synthesis is not a function of the integumentary system. The integumentary system is involved in the synthesis of Vitamin D, maintaining body temperature, detecting sensations, providing protection to underlying tissues, and excreting salts and waste.

The integumentary system, comprising the skin, hair, nails, and associated glands, performs several distinct functions, but not all listed in the options above. The function that does not pertain to the integumentary system is the A. synthesis of vitamin C.

The integumentary system participates in the synthesis of Vitamin D, not Vitamin C. This synthesis happens when your skin is exposed to sunlight. Functions like maintenance of body temperature (thermoregulation), the detection of sensations due to nerve endings in the skin, protection of underlying tissue by acting as a physical barrier, and excretion of salts and wastes, particularly via sweat, are indeed functions of the integumentary system.

Answer:

Actually, it would get soggy. As the heat goes in, the moisture from the oven is sucked into the chicken. So, because the moisture is sucked into the chicken, it gets soggy.

Explanation:

Fried chicken placed in the oven may become more crispy if done at the right temperature and duration but could potentially get soggy if overcooked or exposed to moisture.

The moisture content and oxidation are important for determining the texture and quality of the final fried product.

The correct option is 'B'.

If you fry chicken and then put it in the oven, the result can vary based on several factors, including the temperature and duration of oven-cooking. Generally, putting fried chicken in the oven at a moderate to high temperature can help to dry out any excess oil and make the skin more crispy. This is due to the fact that as water turns into vapor it moves out of the chicken by convection, and the surrounding heat helps to crisp up the already fried coating.

On the other hand, if the oven temperature is too low or the chicken is left in for too long, the skin might potentially get soggy because of the steam from the chicken's internal moisture or any covering that traps moisture could soften the crust.

The final moisture content of fried foods is vital for crispiness. Typically, a fried product is considered crispy if the moisture content is less than 5% by weight. Hence, oven-finishing fried foods should be done at the correct temperature and for the right duration to maintain or enhance crispiness.

Oxidation is another aspect to consider. When fried foods are exposed to the air, they can become rancid due to oxidation. However, if they are consumed quickly or stored properly, this is less of a concern.

Final answer:

The somatic nervous system contains all the sensory and voluntary motor neurons that are involved in conscious or voluntary activities, connecting to the CNS via single-synapse connections where acetylcholine is the main neurotransmitter.

Explanation:

The somatic nervous system only contains all the sensory neurons and the voluntary motor neurons. It is associated with conscious or voluntary activities and is involved in the relay of sensory and motor information to and from the Central Nervous System (CNS). The somatic nervous system consists of motor neurons, which carry instructions from the CNS to the muscles, and sensory neurons, which carry sensory information to the CNS. Unlike the autonomic nervous system, which often has two synapses between the CNS and the target organ, the sensory and motor neurons of the somatic system usually have only one synapse -- one ending of the neuron is at the organ and the other directly contacts a CNS neuron. Acetylcholine is the main neurotransmitter released at these synapses.

Answer:

Aortic arches

Explanation:

Earthworms are grouped in the phylum Annelids and there body is segmented which resemble many little rings attached together. Similarly, earthworms possess circulatory system and circulate there blood through vessels. Thus, there are three (3) vessels that circulate bloods in earthworm which includes: ventral blood vessels, aortic arches and dorsal blood vessels. However,   aortic arches functions like human heart thereby having the responsibility to circulate or pump blood into the ventral and dorsal blood vessels. Furthermore, the aortic arches are known to be the main portion of the artery that bends between ascending and descending aorta.  

Answer:

aortic arches

Explanation:

An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm. These vessels are the aortic arches, dorsal blood vessels, and ventral blood vessels. The aortic arches function like a human heart.

Answer:

raffinose

Explanation:

The least preferred carbohydrate requires the highest concentration of CRP-cAMP to be fully induced. Since the raffinose is the last in the hierarchy it will require the  tho highest concentration of CRP-cAMP. On the other hand maltose would require the lowest level of CRP-cAMP to be fully induced.

CRP is an important regulatory protein in bacteria, which binds to the promoters of the bacteria genes it controls and activates the transcription of the gene. CRP can bind for the promoter only when it is activated by cAMP.

Answer:

To maintain body homeostasis

Explanation:

The endocrine system consists of the endocrine glands that release hormones directly int the blood. Those hormones bind to their receptors on the target cells and thus regulate their function. The major glands are:

pineal gland-releases melatonin, controls sleep cycle

pituitary gland-control growth, blood pressure, thyroid glands and metabolism etc.

pancreas-secretes insulin and glucagon, control of blood sugar levels

ovaries, testes-reproductive role (release female and male hormones)

thyroid gland-controls metabolism and protein synthesis

parathyroid gland-controls Ca levels

hypothalamus-connects nervous and endocrine systems, controls other glands

adrenal glands-release adrenalin and steroid hormones.

The endocrine system functions mainly to control body processes through the production, secretion, and regulation of hormones. These hormones maintain the body's homeostasis and play crucial roles in growth, metabolism, sexual development, digestion, and other bodily processes. The endocrine system works in harmony with the nervous system to adapt to different environmental conditions.

The primary function of the endocrine system is to control body processes by production, secretion, and regulation of hormones. These hormones, secreted primarily by endocrine system cells, tissues, and glands such as the pituitary, thyroid, parathyroid, adrenal, pineal glands, and pancreas, serve as chemical 'messengers' that function in cellular activity and maintain the body's homeostasis. They play significant roles in growth, metabolism, sexual development, digestion, regulation of blood glucose levels, and other normal bodily processes.

The endocrine system adapts to specific environments and conditions. For example, in organisms that undergo metamorphosis, the transformation process, like from a tadpole to a frog, is controlled by the endocrine system.

It is noteworthy that the endocrine system and the nervous system work together to maintain homeostasis and adjust physiological activity when external or internal environmental conditions change. Even different body tissues, such as bone, adipose tissue, heart, kidneys, stomach, small intestine, liver, skin, ovaries, and testes have secondary endocrine functions.

which statement about the deeper part of the ocean floor is true itake animal live in constant darkness

Answer:

Animals live in constant darkness.

Explanation:

The deepest part of the ocean floor does not receive sunlight as solar radiations cannot penetrate to such depth. This part is inhabited by benthos. Since sunlight do not reach to the deepest part of the ocean floor, these organisms are adapted to live in constant darkness.

Absence of sunlight also leads to comparatively colder temperature conditions in the region.

Propofol (another name Diprivan) can be used for Diana's surgery. It is a sedative or anesthesia commonly used for children and adults. Studies show that there were no significant differences in dose requirements based on sex or age, except for the too elderly.  The difference in dosing considering different body weights were not statistically significant also.  The same dose is safe

( 0.1-0.15 mg/kg/min IV for 3-5 min) for Diana, the 210 lb man or a 10-year-old girl. However, the dose was higher in patients with bradycardia and hypotension. 

"The anesthetic choices for Diana Jones, a 5'4"" and 145 pounds individual, would not necessarily be the same as those for a 6'3"" and 210 lbs man or a 4'6"", 65 lb 10-year-old girl. The primary reasons for this are differences in body composition, metabolism, and the pharmacokinetics and pharmacodynamics of anesthetic drugs.

Anesthetic dosing based on weight but influenced by age, height, body composition, cardiac output, liver/kidney function, and health.

Taller, heavier individuals may need higher doses due to larger blood volume and lean mass.

Smaller, lighter individuals require lower doses due to smaller blood volume and mass.

Children require different dosing due to distinct metabolism and sensitivity.

Answer:

Blood pressure is higher in arteries than veins, and the elastic layer helps maintain the structure of the artery.

Explanation:

Blood pressure in arteries is higher because the arteries are the ones in charge of taking the blood that is freshly oxygenated from the hearth and into the body, this means that they have to endure a higher pressure since the blood that they carry is being pushed by the hearth at a certain rate, the veins need to be elastic so the pressure won´t tear them.

The correct option is (c) wrapping tightly around associated proteins.

DNA condensation refers to the process of compacting DNA molecules in vitro or in vivo. DNA tangling and damage are prevented during cell division by packing DNA into chromosomes. For every cell's nucleus to fit within, DNA is compactly packed. Histone proteins and DNA combine to form nucleosomes, which are compact loops.

Nucleosomes coil and stack together to form fibers called chromatin which, in turn, loops and folds with the help of additional proteins to form chromosomes. The genetic material's stability is ensured by the condensed DNA. But most of the time, DNA is only loosely bound to carry out physiological functions like translating proteins.

Thus, in order to fit within a cell, DNA becomes more compact by wrapping tightly around associated proteins.

Answer:

The four types of coal are peat, lignite, bituminous, and anthracite.

Explanation:

The four types of coal are anthracite, bituminous, subbituminous, and lignite. Anthracite has the highest carbon content and energy output, while lignite has the lowest. Bituminous coal is most abundant in the U.S. but has a high sulfur content.

Coal is a combustible sedimentary rock categorized into four main types based on the carbon content and energy potential. The four types of coal, in order of decreasing energy content and carbon value, are:

Anthracite coal: It has the highest carbon content, nearly 100%, and thus provides the most energy upon combustion.

Bituminous coal: This type has approximately 85% carbon and is the most abundant in the United States, although it contains the highest sulfur content.

Subbituminous coal: Has a lower carbon content than bituminous coal.

Lignite coal: Also known as brown coal, it has the lowest carbon content at about 50% and the highest water content, making it the least energy-dense of the four types.

With increasing carbon content, the energy released from combustion also increases. As such, anthracite is used for metallurgical refining due to its high carbon and low sulfur content, while lower-ranked coals like lignite and subbituminous have reduced carbon content and energy output.

IAIA and IAi are genotypes that will give A blood (1/2)

IAIB- AB blood type (1.4)

IBi- B blood type (1/4)

Answer:

C) IA i x IA IB

Explanation:

The genotypes of the parents are (C) C. IA i x IA IB

This is because the mother has blood type A and possesses both the A and B alleles, but the father has blood type A but only carries the A allele. As a result, their offspring have a 50% probability of inheriting blood type A, 25% of getting blood type AB, and 25% of acquiring blood type B.

Furthermore, the offspring will not inherit blood type O since neither parent has the O gene. This genetic combination produces various potential blood types in their kids.
