b. cells do not have much thermal energy; they are relatively cool.
c. temperature is usually uniform throughout a cell.
d. heat can never be used to do work.
Answer:
Temperature is usually uniform throughout a cell (Ans. C)
Explanation:
Heat or thermal energy is a kinetic energy. That is connected with the random movements present in the atoms. Temperature is usually uniform throughout the cell so the most cell can not harness heat to perform work.
Heat is a type of energy which is transfer from one body to another body due to the temperature difference.
It can only perform work if it is transferred from one source which is warmer to a body which is cooler. The temperature in living organisms is usually kept very constant due to the process of homeostasis.
Most cells cannot harness heat to do work because temperatures within the cell are typically uniform, so there's no heat gradient for work to be conducted. Heat tends to be lost instead.
Most cells are not able to harness heat to perform work because heat energy is often dissipated as waste during biochemical reactions. The correct option is c. The temperature is usually uniform throughout a cell. This means that there isn't a high temperature gradient in the cell, which would be needed in order for heat to be used for work. For heat to be harnessed and used for work, there must be a temperature difference because work is done when heat flows from a hotter area to a cooler one. Without a temperature gradient, heat energy cannot be used to perform work within a cell and is instead lost to the surrounding environment.

Answer: the low-pressure areas on the map are the purple triangle and half circles
Explanation:
O helium
hydrogen
Oxygen
Olithium
Answer:
Oxygen
Explanation:
The electrons present in an atom are arranged in shells or orbitals. The electrons are filled into these shells based on their energy levels with those shells closest to the nucleus filled first as they have the lowest energies.
The arrangement of electrons around the nucleus of an atom is known as electronic configuration. The outermost electron shell of an atom is known as a valence shell shell and the electrons found in this shell are known as valence electrons. The electrons usually exist in pairs. The first shell can only contain two electrons; the second shell can contain 8. the electrons are singly filled first before pairing occurs.
The electronic configuration of the atoms of the elements in the option are as follows:
Helium : 1s² ; valence electrons are 2 which are both paired
Hydrogen: 1s¹ ; valence electron is 1
Oxygen : 1s²2s²2p⁴ ; valence electrons are 6 wit two unpaired electrons
Lithium : 1s²2s¹ ; valence electron is 1
Helium has two valence electrons but they are paired as its 1s shell can only contain a maximum of two electrons.
Oxygen has 6 valence electrons. Two of these electrons are paired while the other two are unpaired.
The ability of the brain to acquire information, feelings, and processed, keep, and recollect this for the subject is called memory.
The threes stages of memory are
The ability of Roger to keep memory of the names with these three stages, depends on how pays attention and his ability to process information.
The sensory storage depends on the five sense to send information to his brain. Thus, Roger needs to pay attention to the faces,(iconic memory) voices (echoic memory), feel or touch (Haptic Memory) and (Smell) aroma of perfumes when been introduced to the guest.
These information are retains for few seconds after the guest( the sensation has gone).Thus with this ,he sees every guest as collective set of people without and not as individual. For his brain to process the information as individual he needs to network with the Short memory.
The short memory is the type that retain the information( the names ,voices and touches) of the guests he was introduced to at that present moment. He needs to pay attention and try to retain these sensation to prevent them from been forgotten. These sensations are retain tentatively until the information is processed. It is these processed information that are stored by his brain ,and not the sensory signals like in the sensory.
In order for the processed or interpreted information to be stored and used for longer time, and recalled when needed, these are transferred to the long term memory. This is subdivided into two types; explicit and implicit memory.
He will makes use of the explicit memory because the stored names can be recollected consciously after storage when the 3 types of memories are merged. Unlike the implicit that can not be access consciously.
With the capture of the image of the guest with sensory memory, temporary store the processed names with short term and stored this for future, Roger should be able to remember these names.
Answer:
In this situation, the role of sensory storage would be-
as he enters at reception the smalls, images, would be sensed by him and make its burn the memories in his brain.
Short-Term memory helps in make him remember by the names associated with the small gesture, movement, mannerisms made by them. For example, sam stutters can be remembered as stutter Sam.
Long-Term memory helps in building memory by long haul with help of scenery by relating individuals he already know before the reception and whenever see them mind reminds the name.
Answer:
Studies based on tsh concentrations would indicate whether the thyroid hormones, which are t4 and t3, are in decline or in deficit.
This deficit may be due to a pathology of the thyroid gland and that is why the tsh study is carried out. The TSH hormone is one that stimulates the thyroid gland through the glandular-nervous axis (CNS), if it is in deficit, you want to say that it is being poorly stimulated.
Other findings of hypothyroidism are overweight, decreased basal metabolism, alterations in the cardiovascular system, and increased blood pressure.
That the TSH hormone is elevated, and there is a deficiency of t4, means that the hormone is suffering from some neoplasm, or some pathology that does not collaborate with the function of the gland, that is, that the axis between the central nervous system and The thyroid gland works perfectly, but what is defective is the gland, the body itself captures this deficit of t4 and stimulates the neuronal pathway even more, releasing more TSH, to overstimulate the thyroid gland and that it can generate the amount of t4 required.
The nurse seeks to know that if by administering t4 and balancing the values of this thyroid hormone, TSH normalizes and returns to its normal value, that is, it decreases and does not overstimulate the thyroid gland.
In the event that TSH does not decrease as expected, there will be a double problem to be solved, one at the nervous level and the other at the glandular level.
On the other hand, if the TSH level normalizes, we could understand that the TSH was increased because it wanted to "solve" the t4 deficit.
Explanation:
The thyroid gland works thanks to the stimulation exerted by the central nervous system through TSH.
The TSH hormone is the one that is responsible for stimulating the exact and fair secretion of t4 and t3, sometimes it tends to increase, due to negative feedback, since the increase in t4 and t3 causes the tsh to decrease and the right balance is reached . In case the hormones secreted by the thyroid are in deficit, this will be captured by the body and will not have this negative feedback, therefore the stimulation of the nervous axis will be increased.
The thyroid gland can suffer from metabolism syndromes where hypoactivity or hypothyroidism is detected, or hyperactivity which is also known as hyperthyroidism, although these syndromes are not the only ones, there are also other pathologies such as malignant and benign neoplasms, hashimoto's disease, among others.
