How do cells maintain homeostasis in different environmental conditions?
[tex]\huge\pink{Answer}[/tex]
Homeostasis at the cellular level is critical to maintaining homeostasis in the whole organism. Animal cells have several ways to help them stay in equilibrium.
Cell Membrane and Phospholipid BilayerThe cell membrane functions as a boundary separating the internal cellular environment from the external environment. It is selectively permeable which means it lets some materials pass through but regulates the passage of other materials.
Ion Transport MechanismsThere are several ion transport mechanisms within the cell membrane that function to maintain proper levels of solutes inside and outside the cell. One of the most important is the sodium-potassium ATPase pump.Another critical pump is the calcium ATPase pump which moves calcium out of the cell or pumps it into the endoplasmic reticulum. This transfer of ions back and forth across the membrane creates a membrane potential that drives the ionic currents.
Cellular CommunicationThere are three basic kinds of intercellular communication used to maintain homeostasis. The first is when direct contact occurs between the membranes of two cells and they signal to each other. The second is when cells use short range chemical signals over short distances. The third is long ranged signals that are secreted into the bloodstream and can be carried anywhere in the body.
HOPE IT HELPS ☺️The average temperature of the surface of Earth has increased approximately 1°C in
the past century. Which reason best explains this increase in temperature?
Th average temperature of the earth has been increased as a result of
higher level of carbon dioxide and other greenhouse gases in the
atmosphere.
The carbon dioxide and other greenhouse gases has increased over the
past century as a result of the emission of these gases by automobiles,
industries etc.
These gases deplete the ozone layer which is responsible for the
absorption of sun rays .When this happens, the sun rays reaching the earth
will be increased thereby causing an increase in temperature.

8. Explain why young adults coming into the ER with brain
swelling are often asked about drug use?
Answer:
Over the past several years, the misuse of opioids – ranging from prescription painkillers to black tar heroin – has reached epidemic proportions. In 2015, the Media Research Center reported that drug overdoses had surpassed motor vehicle accident fatalities nationwide for the first time. Since 1999, nearly 200,000 Americans have died from a prescription drug overdose. Heroin use increased in response to advocate and lawmaker efforts to restrict overprescribing, doctor shopping, and opioid sales via online pharmacies. As prescription drug overdoses fell from 2010 to 2015, the number of heroin overdoses tripled.
Opioids are synthetic or semi-synthetic substances originating from the poppy plant. Examples include heroin, Fentanyl, and prescription opioid painkillers, all of which operate in the same fashion, albeit with varying degrees of strength. Synthetic opioids are among the most dangerous and addictive. The synthetic opioid Fentanyl, for example, is 25 to 50 times more potent than heroin, which is a semi-synthetic substance.
The National Institute on Drug Abuse explains, “[Opioids] act by attaching to specific proteins called opioid receptors, which are found on nerve cells in the brain, spinal cord, gastrointestinal tract, and other organs in the body.” When substances attach to these receptors, they change how the brain perceives pain and instead produce feelings of euphoria. They also slow essential body functions, such as heart rate and breathing.

The____
gland controls water balance, growth, and blood pressure
pituitary
Thymus
thyroid
pancreas
Answer:
The pituitary gland controls water balance, growth and blood pressure.
Explanation:
The pituitary gland is also called hypophysis, and is a small gland located in the skull that is responsible for secreting hormones and coordinating the activity of other glands.
Hypophysis is usually divided into two portions, adenohypophysis or anterior lobe and neurohypophysis in posterior lobe. Among other functions, the pituitary gland is in charge of
Water balance and blood pressure, through the antidiuretic hormone or ADH secreted by the neuro-pituitary. Growth, through the secretion of growth hormone or GH, secreted by the somatotropic cells of the adenohypophysis.This gland is also responsible for the secretion of oxytocin and other hormones in charge of regulating endocrine glandular activity.
Regarding the other options:
Thymus is a gland present in children and related to immune function. Thyroid is responsible for secreting hormones that control basal metabolism. Pancreas has exocrine and endocrine function, producing digestive enzymes and insulin and glucagon, respectively.Answer:
A.pituitary

How do enzymes affect the reactions in which they take part?
A.Most enzymes slow down chemical reactions.
B.Enzymes decrease the activation energy of the reaction.
C.Enzymes increase the activation energy of the reaction.
D.Enzymes are converted into products in the reaction.
Answer:
B. Enzymes decrease the activation energy of the reaction :)
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

When does species richness increase at the fastest rate? Why is this possible?
Explanation:
As temperature increases, species richness tends to increase up to a maximum, beyond which water deficits then begin to depress richness
As temperature of the waterbody increases, the species richness tends to increase up to a maximum level, beyond this value water deficits which begins to depress the species richness.
What is Species Richness?Species richness is the number of different species present within a defined region. Species richness is commonly described by an index known as the Shannon's index 'H'.
Temperature has an important influence on the distribution of organisms in an area because it determines the physical state of the water body. Most organisms cannot live in conditions when the temperature remains below 0°C or above 45°C. The organisms cannot adapt to these extreme temperature ranges.
Temperature has been shown to increase the species interactions by increasing attack rate on species.

Note: Your teacher will grade your responses to questions 24‒25 to ensure you receive proper credit for your answers. What circumstances would cause an organism to adapt? In your answer, be sure to explain the differences between both short- and long-term adaptations. Use an example to explain your answers.
Answer:
Explanation:
Usually, adaption is triggered by the need to survive and reproduce. Short-term adaption is usually caused by a sudden change in circumstance which causes the need for behavior or tactics to change based on previous experience or knowledge. Long term adaption is different, this usually occurs naturally over the course of many decades in order for the species to have better chances of surviving in the changing environment that they are living in.
