Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.
To melt the ice during the winter season, road crews often put sand and salt solutions on the roadways to help melt the snow and ice. The plants that live close to the road often die or wilt after this procedure. Using your knowledge of osmosis and plant structures, which type of solution would cause this to happen to plant cells? Group of answer choices
Answer:
The missing answer choices are:
a. hypotonic
b. isotonic
c. osmosis
d. hypertonic
The correct option is d. hypertonic
Explanation:
A hypertonic solution has a higher concentration of solutes than the concentration of solutes present inside the plant. As there is a difference in concentration between the inside and the outside of the plant, the plant loses water in an attempt to balance the difference. As a result, there is an excessive loss of water that dehydrates the plant and kills it.
if you were facing a rainbow where would your shadow be
Answer:
Usually the radius of the arc is equal to about one-fourth of the visible sky, or 42 degrees, to the red. When there are showers nearby, simply look in the part of the sky opposite the sun at a 42-degree angle from your shadow; if there is a rainbow, that is where it will be.

Climate change has begun to affect insects as food resources have started disappearing . The monarch butterfly and the queen butterfly have to compete for the same food source . This is an example of____competition.
A. Co-species
B. Intraspecies
C. Interspecies
D. Habitat
Answer:
B.
Explanation:
In an ecological environment living things of different or same species compete with each other for the limited resources available. It is a symbiotic interaction between these living things.
There are two types of competition between these living beings- intraspecific and interspecific. In the given scenario, it is an intraspecific competition between the monarch butterfly and the queen butterfly.
Intraspecific competition is a competition between two living beings of the same species.
The monarch butterfly and the queen butterfly both belong to the same species- danaus.
Therefore, option B is correct.

what did this have to do with biology ?
Forensic biologists are testing a DNA sample that has no match found in the system using SNP analysis. What helpful information could the biologists get from the SNP?
The sample was taken from someone with brown hair and blue eyes.
The sample was taken from an animal.
The sample was taken from an elderly person.
The sample was contaminated during collection.
Answer:
Option D
Explanation:
The SNP analysis is useful in determining response of an individual towards a drug and its environmental susceptibility. Thus, the SNP analysis in this case will give an indication of whether the sample was contaminated or not.
Hence, option D is correct
Which of the following is an
organelle?
A. a brain
B. a cell
C. lungs
D. a nucleus
Cancer cells Group of answer choices are dedifferentiated. are impossible to grow in culture. are particularly sensitive to extracellular signals. divide uncontrollably and then die.
Answer:
The options are not complete, here are the remaining options from other websites.
d. divide uncontrollably and are immortal
e. have an extra set of chromosomes, which keeps them dividing.
The correct answer is divide uncontrollably and are immortal .
Explanation:
This because cancer cells are abnormal cells that divide uncontrollably and does not follow the normal cell cycle. abnormal cell that doesn't follow this cycle. Instead of them to die, the car continually reproduce more abnormal cells that can easily invade nearby tisssues. They can travel to all part of the lymph and body parts.

What is the purpose of mitosis?
Answer:
Mitosis creates more diploid cells by copying each chromosome and moves it to the other side of the cell.

en donde se produce La citocinesis
La citocinesis ocurre al final del ciclo celular después de la mitosis o meiosis. En la división de células animales, la citocinesis ocurre cuando un anillo contráctil de microfilamentos forma un surco de escisión que pellizca la membrana celular por la mitad. En las células vegetales, se construye una placa celular que divide la célula en dos.

B. False

Please help it’s biology!!!!!!
Answer:
25%
Explanation:
If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.
Create a punnett square to find possible offspring
AA = Blood type A
AO = Blood type A
OO = Blood type O
There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.
1÷4×100 = 25

why is it important for plant's to store food?
Answer:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.
Explanation:
How is the equilibrium constant calculated?
