In order for a protein to be an integral membrane protein it would have to be which of the following?
Answer:
Integral membrane proteins
Explanation:
also called intrinsic proteins, have one or more segments that are embedded in the phospholipid bilayer. Most integral proteins contain residues with hydrophobic side chains that interact with fatty acyl groups of the membrane phospholipids, thus anchoring the protein to the membrane.
Throughout the day, activities in the liver, kidneys, and endocrine glands undergo large changes. Body temperature, blood pressure, and amino acid levels also shift from hour to hour. In fact, people tend to be more energetic and alert when these and other activities are at their highest point once a day. This is a description of Group of answer choices
Answer:
Circadian rhythms.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). All living organisms (both plants and animals) respond to changes in their environment and as such an appropriate reaction or response is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Since both plants and animals respond to environmental stimuli, it simply means that, these living organisms have physiological cycles referred to as circadian rhythms.
Circadian rhythms is a natural internal process that controls the physical, mental, and behavioral changes in living organisms such as the sleep-wake cycle. The circadian rhythm is simply the internal body "24 hour" clock.
For example, there are large changes in the activities that happens with respect to the organs such as kidney, liver and endocrine glands within the body of living organisms throughout the day. Also, they experience timely shift in blood pressure, amino acid levels, body temperature, metabolism, etc.
Hence, living organisms are usually more energetic and at alert when the aforementioned activities and others are at their highest point once a day as a result of circadian rhythms.

Overlying, adjacent plates are pulled apart when magma convection currents flow away from one another.
What is magma conventions?Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.Hence, option E is correct.

why do prevailing winds and positions of islands cause warm ocean currents to pass Christchurch in normal years
Prevailing winds and positions of islands cause warm ocean currents to pass Christchurch in normal years for the following reasons:
The prevailing winds in the region are generally from the southwest.The position of islands such as New Caledonia and Norfolk Island can also influence the movement of warm ocean currents in the region. In the case of Christchurch, there are a few reasons why warm ocean currents tend to pass by the region in normal years:Warm ocean currents are typically driven by prevailing winds, oceanic currents, and other factors such as the shape of coastlines and the positions of islands.
The prevailing winds in the region are generally from the southwest. These winds blow parallel to the coastline, which means that warm ocean currents are deflected away from the shore and towards the east. As a result, the waters off the coast of Christchurch are generally cooler than those further north or northeast. The position of islands such as New Caledonia and Norfolk Island can also influence the movement of warm ocean currents in the region. These islands help to direct the flow of warm water towards the Coral Sea and the Tasman Sea, rather than towards the coast of New Zealand. This means that Christchurch, which is located on the eastern coast of the South Island, is less likely to experience the effects of warm ocean currents.Note: That oceanic currents and winds can be affected by a range of factors, including El Niño and La Niña events, which can cause changes in sea surface temperatures and alter the path of ocean currents. As a result, there may be some years when warm ocean currents do reach Christchurch, even if this isn't typically the case in normal years.

5. One of the most important steps to achieve a more sustainable future is to reduce a. Water conservation b. Overconsumption c. Population growth d. Both B and C
Answer:
B.
*Read the explanation plz
Explanation:
A actually increases sutainability, and C is just wrong. It's technically saying that we should not let humans be born, we shouldn't let people get pregnant, which of course no one is gonna listen to. So B is right because if we consume too many things, the next generation won't have as many resources as they need to survive.
What is the answer to this question
A breeder is trying to decrease the maturation time in a population of sunflowers. In this population, the mean time to flowering is 100 days. Plants with a mean flowering time of only 90 days were used to produce the next generation. If the narrow-sense heritability for flowering time is 0.2, what will the average time to flowering be in the next generation
Answer:
The next generation average time to flowering will be 98 days.
Explanation:
Before answering the question, we need to know a few concepts.
Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations. Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced. The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,SD = Xs - X₀
Heritability in the narrow-sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.h² = R/SD
The response to selection (R) refers to the metric value gained or lost from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.R = h²SD
R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),
R = X₀ - X₁
-------------------------------------------------------------------------------------------------------------
Now that we know these concepts and how to calculate them, we can solve the proposed problem.
Available data:
trying to decrease the maturation time in a population of sunflowers.the population mean time to flower is 100 days → X₀Chosen parental Plants mean flowering time is 90 days → Xs the narrow-sense heritability for flowering time is 0.2 → h²According to what we sow previously, we need to find out the value of X₁, which reflects the next generation average time to flowering.
We know that R = X₁ - X₀, so we need to clear this formula to calculate X₁X₁ = R + X₀
We already know that X₀ = 100 days,
Now we need to calculate R.
R = h²SDWe know that h² = 0.2,
Now we need to calculate SD
SD = Xs - X₀Xs = 90 days → Parentals media flowering time
X₀ = 100 → Population media flowering time
SD = Xs - X₀
SD = 90 - 100
SD = - 10 days
Knowing this, we can calculate R
R = h²SDo h² = 0.2
o SD = - 10
R = 0.2 x (-10)
R = - 2
Finally, once we know the R-value we can calculate the X₁ valueX₁ = R + X₀
X₁ = - 2 + 100
X₁ = 98

When a person undergoes gastric bypass surgery, can their hunger, appetite, and
satiety cues change?
Answer:
Yes
Explanation:
Yes, after an individual undergoes gastric bypass surgery many different metabolic hormones become affected by the surgery. Such hormones include Gherlin, Leptin, Gastrin, and Insulin, all of which can affect the individual's hunger, appetite, and satiety cues. This is mainly because the surgery greatly shrinks the amount of food that an individual can eat at any given time. Since it basically shrinks the stomach by creating a small pouch where food enters and goes straight into the intestinal track it gives the individual the feeling of being full with much less food.

#Hope it helps!
Sucrose is not a simple sugar because it is made up of both glucose and fructose so sucrose is called a disaccharide. Therefore, option (D) is correct.
What is simple sugar?A monosaccharide, often known as a simple sugar, is a form of carbohydrate that cannot be broken down into smaller molecules of glucose and is thus readily absorbed by the body.
There are three primary kinds of simple sugars: glucose, fructose, and galactose. All of these sugars have the same chemical composition, but their structures are quite different from one another.
Sucrose on the other hand is a disaccharide composed of both glucose and fructose. Therefore, it is not a simple sugar and can be broken down into smaller or simpler molecules.
