What is the function of each of these structures in the cell membrane? a) phospholipid bilayer b) peripheral protein c) integral protein d) glycolipid & glycoprotein e) cholesterol
Answer:
The correct answers are described in the Explanation section.
Explanation:
The function of the structures in the cell membrane are as follows:
a) phospholipid bilayer: comprised of fatty acids and alcohol, the phospholipid bilayer acts as a hydrophobic barrier to avoid the uncontrolled transport of molecules and ions.
b) peripheral protein: they are proteins present in the external surface of the cell membrane. This proteins form temporary bonds between the cells and other molecules, attaching and detaching at specific times.
c) integral protein: this proteins have one part of its structure in the surface and other part within the cell membrane. They have different roles, including: receptors, transporters, linkers, channels, among others.
d) glycolipid & glycoprotein: proteins that have carbohydrate-bearing portions in its extracellular environment. They maintain the stability of the cell membrane and facilitate cellular recognition.
e) cholesterol: cholesterol structure helps to the packing of the phospholipids, which restricts the passage of the molecules.

The number of valence electrons an element has changes often, so we cannot use the periodic table to predict the number of valence electrons an element
has
True
False
Answer:
False
Explanation:
The number of valence electrons on an element is also the same or else it would be a different element.
The statement that the periodic table cannot be used to predict the number of valence electrons is: FALSE
The number of valence electrons an element has will always remain the same for the element to remain the same element, elese the element will changes with a change in valence electrons. therefore we can use the periodic table to predict the number of valence electrons that an element has.
A valence electron is an electron that is located in the outermost shell of an atom or element. It is negative and it is used for the formation of bonds between atoms or elements.
Hence we can conclude that The statement that the periodic table cannot be used to predict the number of valence electrons is: FALSE .

Yes
Criminals might steal DNA to use the genetic identity of their victim
Answer:
yes and no
Explanation:
if someone actually stole your DNA you wouldn't be alive right now,
but if someone stole "parts" of your DNA you would still be the same person because it doesn't matter what you look like you are your own person an example of this are identical twins, identical twins share the same exact DNA but they aren't the exact same person since they both can like different stuff and have different personalities. but if you mean in a biological stand point "if someone stole your DNA, could they steal your identity" of course not, at least not with our technology.

Nitrogen is required for protein formation. What is responsible for the bulk of nitrogen fixation?
A.
air
B.
animals
C.
bacteria
D.
lightning
Answer:
The factor with the responsibility for nitrogen fixation is bacteria (option C).
Explanation:
The nitrogen that contributes to the formation of proteins comes from plants. Due to the inorganic nature of nitrogen, plants require bacteria to contribute to the assimilation of this element, a process called biological nitrogen fixation.
Nitrogen fixing bacteria in plants are called diazotroph and, in some cases, establish a symbiosis with the plant's roots, the rhizobia.
The other options, air, animals and lightning, do not correspond to biological nitrogen fixers with the ability to incorporate nitrogen into plants.Which statement about carcinogens is TRUE? *

2. List the inputs and outputs of
photosynthesis. What part(s) of
the plant are responsible for
taking in each of the inputs?
Answer:
Inputs: carbon dioxide (CO2) and water (H2O)
Output: Sugar (C6H12O6) and oxygen
- Roots take in water
- Leaves take in carbondioxide
Explanation:
Photosynthesis is a unique metabolic process undergone by only set of organisms called AUTOTROPHS. Autotrophs are capable of synthesizing their own food by capturing light energy (from sun) and using it to make food (sugars).
This photosynthetic process requires certain substances called INPUTS, which are basically carbon dioxide (CO2) and water (H2O) and give out products called OUTPUTS, which are sugars and oxygen gas.
- The CO2 input is taken in by the plant via the stomata on its leaves while the water (H2O) is absorbed by the roots of the plant.
Jasmine is a healthy girl who is playing outside. Her internal body temperature rises to 38 degrees Celsius, which is above normal. How does her body most likely respond to help her return to homeostasis?
Answer:
See the answer below
Explanation:
Jasmine's body would help her return to homeostasis by using the negative feedback loop.
The negative feedback loop works to negate the process or processes that lead to the body's setpoint being breached. The setpoint refers to the normal range of operation of body processes such as temperature, pressure, etc.
The skin of Jasmine acts as a sensor and sends information to the control center, the brain. The brain reads the temperature data, finds out that the setpoint has been exceeded, and sends information to the effectors to initiate processes that will return Jasmine's body temperature to normal.
One of the effectors, the blood vessels that supply blood to the skin becomes dilated. Consequently, more blood is supplied to the skin and more heat is lost from the skin due to radiation - blood being a conductor of heat in the body. Another effector, the sweat glands, release sweat to the skin. The evaporation of sweat from the surface of the skin causes the body to cool down. These processes work synergistically to return the body temperature of Jasmine back to homeostasis.

Explanation:
As thermal energy is added to a substance, which of the following changes can be predicted?
O
Spacing between particles will decrease
Vibration of individual particles will increase
Temperature of the substance will decrease
The pressure of the air around the substance will increase
Answer:
Vibration of individual particle will increase
Explanation:
This is due to the fact that whenever any substance of matter is increased in temperature, the atoms begins to move away from each other. Take for instance an ice cube for example, when an ice cube (a solid) is heated it becomes water, (a liquid). Proving that when a substance is heated, no matter the density of the material, the individual particles, or atoms, begins to spread apart.
What characteristic of water helps in regulating cell temperature and maintaining homeostasis?
Someone please help i need a claim, evidence, then a reasoning !
Answer:
The characteristic of water that helps regulate the temperature of the cells and maintain homeostasis is specific heat (Claim).
Explanation:
Specific heat is a physical property that is defined as the amount of heat needed to raise one gram of a substance by one degree Celsius. In the case of water, its specific heat is higher than that of other substances, being its value 4.186 joules/gram °C, or also 1 calorie/gram °C.
- Claim: The property of water that allows cells to regulate temperature and maintain homeostasis is specific heat.
- Evidence: a high specific heat value of water means that in bodies that possess this molecule in large quantities it is more difficult to raise the temperature
- Reasoning: Living beings are formed mostly by a high percentage of water, much of it in the intracellular compartment. The specific high heat of the water makes it difficult to have sudden changes in the internal temperature, even when the environmental temperature is high, which is a property of water that allows thermoregulation and maintains the balance or homeostasis.
Because molecules will move from one side to another to come to an equilibrium, or balance of concentration, the _________________________moves from side B to side A, so the water level on side A goes _____________________________.
Answer:
Water, up
Explanation:
In the process of movement water in the diffusion of water the net movement of water goes from higher concentration to the low concentration area. The movement of water move form one side to other side until it reaches an equilibrium and the level of water on the other side goes up.
Hence, the water molecule will move from from side B to side A until it reaches equilibrium and the water level on side A goes up.
