<span>False
 Asphalt is still considered a fossil fuel, as anything that is a made up of hydrocarbons that is created from ancient biological origin is defined as such. They are not used for any sort of resource extraction due to their preserved status for study, but would still classify under the definition.</span>

Which hormone is secreted during periods of stress and is related to increased risk of disease?
gulaghasi [49]

Stress is a condition that tends to disturb the equilibrium of the individual with the environment. There are hormonal changes which occur during stress and have their impact in the endocrine system.

Reaction to stress is associated with increased hormone secretions of several hormones such as glucocorticoids, growth hormone, prolactin and catecholamine. The elevated levels of these hormones increase the risk of infections and also decrease the innate immunity as well as increase the autoimmune responses.

There are endocrine disorders related with the increased hormone secretion during stress conditions such as psychosexual dwarfism, obesity, Grave’s disease and gonadal dysfunction. The effect of increased secretion of the hormones is increase in mobilization of energy and adaption of the individual to current circumstances.

Activation of the pituitary adrenal axis is an important and dominant response due to stress. On stimulation of the pituitary adrenal axis results in hypothalamic secretion of the CRF (corticotrophin-releasing factor) which further stimulates the pituitary to ACTH, 3-endorphin and 8-lipotropin.

During stress, the plasma levels of these hormones increase up to five times.

The stimulation of the pituitary adrenal axis is also associated with the release of hormone catecholamine. The increased level of catecholamine leads to increased skeletal muscle flow of blood increased cardiac output and glucose levels, bronchiolar dilation, cutaneous vasoconstriction etc.

Acute stress releases vasopressin rapidly from the Para ventricular nucleus of hypothalamus together with corticotrophin releasing hormone.

During stress there is also suppression of gonadotropins and gonadal steroidal hormones which disrupt the normal menstrual cycle and prolonged stress can also lead to impairment of reproductive functions.

Thyroid functions are down regulated during stress conditions. T3 and T4 levels decrease whenever there is any stress condition.

The growth hormone level increases due to physical stress and prolactin level may increase or decrease depending on the conditions of regulatory environment locally.

g Electron flow down the electron-transport chain leads to the transport of proteins: Group of answer choices from the matrix to
guajiro [1.7K]

Answer:

from the intermembrane space to the matrix

Explanation:

In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.

Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.

NEED IT ASAP!! I WILL MARK A BRAILIEST
mihalych1998 [28]

Since Lithium has one valence electron that means it needs to lose it to form a stable structure. That means it's valence is equal to one. Oxygen has six atoms, in order to form a stable octet structure it needs to accept 2 electrons, therefore it's valence is 2.

Therefore two Lithium atoms bond with one oxygen atom to form Li2O

Plz help! I'll give brainliest, follow, and points!!
Leni [432]

Answer:

There are many reasons why manned space probes to Saturn are simply  unachievable. Getting to space is incredibly hard. The force of gravity is very hard to escape. If you wanted to, you would have to invest trillions upon trillions of dollars to create a space shuttle that may or may not explode. Second, we simply don’t have the technology to make it that far with a manned probe. Saturn is more than a billion miles away. It would take more than several years to go that far. To keep astronauts alive, entertained, and sustained is also a big challenge. In conclusion these are some reasons why a manned space probe to Saturn is unachieveable.

Explanation:

U’d better give me that brainly.
