Passive membrane transport processes include ________. movement of a substance down its concentration gradient movement of water from an area of low concentration to an area of high concentration consumption of ATP the use of transport proteins when moving substances from areas of low to high concentration
Answer:
movement of a substance down its concentration gradient
Explanation:
As you may already know, the plasma membrane of a cell has a semi-impermeable nature. This means that the plasma membrane allows only a few very specific substances to pass in and out of the cell. This movement of subtlety can happen in a passive or active way. In an active way, the moment is made through proteins of the membranes. Passively, the movement is made through a concentration gradient, where the substance is able to pass from the more concentrated side to the less concentrated side.
Which of the following processes depend on fusion?
A. the atomic bombs used in World War II
B. the energy production in the sun
C. the geothermal heating in the mantle of the Earth
D. the energy production in nuclear reactors
Answer:
B. the energy production in the sun.
Explanation:
The sun ngenerates its energy by nuclear fusion of hydrogen nuclei into helium.
The right answer to the provided question is that the sun's energy generation method is based on fusion.
How nuclear fusion occurs in sun?
Nuclear fusion is the process that occurs when two or more atomic nuclei unite to generate one or more distinct atomic nuclei and subatomic particles neutrons or protons.
The mass differential between reactants and products results in either energy release or absorption.
In the Sun's core, hydrogen is being converted into helium. This is referred to as nuclear fusion.
The fusion of four hydrogen atoms produces one helium atom. During the process, some of the mass is converted into energy.
So, we can conclude that Nuclear fusion occurs within the sun's core. Because of the amount of pressure within the sun, nuclear fusion occurs at its core.

Explain how the central nervous system and the peripheral system work together to keep the body activities in balance.
Answer:
Voluntary motions in the skin, bones, joints, and skeletal muscles are controlled by the somatic nervous system. Both of these PNS systems collaborate with the CNS to control physiological functions and offer responses to external stimuli.
Explanation:
The central nervous system and peripheral nervous system work together as the nerves of PNS comes out from CNS and the peripheral nervous system guide the brain and spinal cord to receive signals from the body to work.
What is the nervous system?The nervous system is divided into two parts, the central nervous system, and the peripheral nervous system. The central nervous system consists of the brain and spinal cord. The peripheral nervous system contains all the nerves which came out from the brain and spinal cord.
Both systems work together as the nerves of the PNS connected with the brain and spinal cord. The nerves signal the brain and brain when giving signals, they travel through the nerves to the body.
Thus, together, the central nervous system and peripheral nervous system control how the brain and spinal cord receive signals from the body to function. The central nervous system sends PNS nerves out from the spinal cord.

Research has found that chimpanzees in one area make spears to help them hunt bushbabies (African lorises). The chimpanzees locate a tree trunk in which the bushbabies live. They then select a tree branch, trim off the leaves and side branches, and trim the end of the branch to form a sharpened tip. The chimpanzees thrust these branches, like spears, into the tree to try to stab bushbabies (see the Lab 11 Exercise Image Library on p. 336 of your lab manual for associated images).
Is this behavior an example of nonhuman primate culture?
1. Yes
2. No
Primates often work together while hunting and then share the meat with others in the group.
1. True
2. False
Answer:
1. Yes
1. True
Explanation:
A.
Yes, it is a nonhuman primate cultural example: Despite the fact that many nonhuman primates lack apparent cultural traditions in the same manner that humans do, primatologists have uncovered a number of behavioral habits that differ between populations and are passed down through socialization and language interaction. The employment of tools by chimps for hunting is one of the most prominent examples of this. Chimpanzees in the African Savannah have been observed fashioning sticks into weapons to hunt bush infants, according to researchers. In each example, a chimp changes a branch by snapping off one or two ends and sharpening the stick with its teeth. The spear is then jabbed into the bottom of the trunk, where the bush infants slumber. Because this complicated behavior appears to differ between communities, it is thought that chimpanzee tool usage is socially acquired, and hence a cultural behavior.
B.
Chimpanzees hunt in groups so that they may corner their prey even if the canopy is continuous. Each chimpanzee within the hunting parties has a specific function to play during an arboreal hunt. Drivers are responsible for keeping the prey moving in a specific route and following them without trying to grab or catch them. Blockers are positioned at the base of the trees, climbing up to stop prey from fleeing in the other direction. Chasers move swiftly and attempt to capture the prey. Finally, when one monkey approaches, ambushers hide and flee. The food is delivered to all members of the hunting group once the animal has been trapped and slaughtered.
Community ecologists study the factors that determine the abundance of different species. The Abundance of three algae species (in mg/mL) is quantified in two different lakes before and after an unusually hot summer. The coordinates of these four samples inR3are (i) Lake A: (97,84,43)and (100,80,50) before and after summer, respectively, and (ii) Lake B: (23,59,22) and (20,63,15)before and after summer, respectively.(a) How does the magnitude of the change in algal community compare between the two lakes
Answer:
Explanation:
Given that:
The abundance of three algal species in Lake A is now represented by the vectors:
[97, 84, 43] and [100, 80, 50]
Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:
a = [100 -97, 80 - 84. 50 - 43]
a = [3, -4, 7]
Thus, the magnitude of that change is:
[tex]|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}[/tex]
[tex]|a| = \sqrt{9+16+49}[/tex]
[tex]|a| = \sqrt{74}[/tex]
[tex]|a| =8.6 \ mg/mL[/tex]
The abundance of three algal species in Lake B is now represented by the vectors:
[25, 59, 22] and [20, 63, 15]
At Lake B, the change occurring in the vector of algae species can be determined as:
b = [20 -23, 63 - 59. 15 - 22]
b = [-3, -4, -7]
Thus, the magnitude of that change is:
[tex]|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}[/tex]
[tex]|b| = \sqrt{9+16+49}[/tex]
[tex]|b| = \sqrt{74}[/tex]
[tex]|b| =8.6 \ mg/mL[/tex]
Hence, for both Lake A and B, the magnitude of change is the same.

There are advantages and disadvantages to both types of microscopes. Compare and contrast the two types outlined
here. What evidence supports a DISADVANTAGE of the transmission electron microscope?
A)
The beam of electrons used in the transmission electron microscope often
damage the delicate specimens being observed.
B)
C)
The transmission electron microscope magnifies specimens to a much
higher degree than an optical microscope and therefore requires a very
thin specimen.
The transmission electron microscope requires that specimens be put
inside a vacuum chamber so the microscope cannot be used to observe
living specimens.
The typical electron microscope can zoom in at only a few discrete levels
and often specimens are best observed at intervals not reached with this
microscope.
D)
Answer: C
Explanation: I just did it on usa test perp
The transmission electron microscope requires that specimens be put inside a vacuum chamber so the microscope cannot be used to observe living specimens. The correct option is C.
What is electron microscope?The technique of electron microscopy (EM) is used to obtain high-resolution images of biological and non-biological specimens.
In biomedical research, it is used to investigate the detailed structure of tissues, cells, organelles, and macromolecular complexes.
An electron microscope can only be used in a high vacuum. This makes using a microscope to study living organisms impossible because they would evaporate and disintegrate under such conditions.
Transmission electron microscopy is a microscopy technique in which an image is formed by passing an electron beam through a specimen. The specimen is usually an ultrathin section less than 100 nm thick or a grid suspension.
Because the transmission electron microscope requires specimens to be placed inside a vacuum chamber, it cannot be used to observe living specimens.
Thus, the correct option is C.

Explanation:
Epinephrine causes the enzyme glycogen phosphorylase to break down glycogen within a cell. Epinephrine performs this task on intact cells, meaning cells that have a membrane (not just cell contents placed in a medium). What does this fact reveal
Answer:
The fact that it reveals is that:
Epinephrine binds to the receptor tyrosine kinase on the cell membrane and does not act on glycogen phosphorylase.
Explanation:
In cellular respiration, epinephrine is a neurotransmitter and a plasma membrane hormone receptor. It is not a lipid-derived hormone, but rather an amino acid-derived hormone. As a result, they are unable to pass through the plasma membrane of cells. They bind to receptors on the outer surface of the plasma membrane through plasma membrane hormone receptors (receptor's tyrosine kinase of the cell membrane) because they are lipid insoluble hormones.
Unlike steroid hormones, lipid insoluble hormones (epinephrine) do not directly influence glycogen phosphorylase or the target cell because they cannot enter the cell and operate directly on DNA. The activation of a signaling pathway occurs when these hormones attach to a cell surface receptor; this activates intracellular activity and performs the hormone's specific effects. Nothing crosses through the cell membrane in this fashion; the hormone that binds at the cell's surface stays at the cell's surface, while the intracellular component stays within the cell.
in the fermentation experiment using yeast with the different sugars what was the dependent variable
Answer:
The dependent variable is fermentation rate.
Explanation:
When finding dependent variable phrase it like this:
______ depends on _____.
Where the first blank is the dependent variable and the second blank is the independent variable. For example, if I were to test the effects of pH on an enzyme, I would say the function of the enzyme depends on the pH level. This makes the function of the enzyme the dependent variable. In this case, fermentation rate depends on the different sugars. Hope this helps!
