where are peripheral proteins located
Answer:
Explanation:
Peripheral membrane proteins are found on the outside and inside surfaces of membranes, attached either to integral proteins or to phospholipids. Unlike integral membrane proteins, peripheral membrane proteins do not stick into the hydrophobic core of the membrane, and they tend to be more loosely attached.

rate of reproduction to sexual reproduction in plants
Answer: Asexual reproduction
For example, sexual reproduction allows for variation, but gestation usually takes a long time and it requires heavy parental input. Asexual reproduction occurs quickly, but because all of the offspring have the same genetic information, individuals are more susceptible to disease.

How is active transport different from simple diffusion and facilitated diffusion?
Answer:
Active transport is when substances move against the concentration gradient and go from low to high. Diffusion is when substances move with the concentration gradient and go from high to low.

Tissues and organs
Molecules and cells
Organs and organ systems
Organ systems and organism
Answer:
Molecules and cells

A class is debating the advantages and disadvantages of different types of reproduction. One student argues that organisms that reproduce asexually, like bacteria, have no advantage over organisms that reproduce sexually.
Which of the following choices below represents an argument for the advantages of asexual reproduction?
A. Organisms that reproduce asexually are likely to find a mate at a faster rate than sexually reproducing organisms, which allows them to reproduce faster.
B. Organisms that reproduce asexually are more diverse and are more likely to pass on key genes for survival to future generations, which aids in maintaining beneficial genes for survival in the gene pool
C. Organisms that reproduce asexually gain variation through processes like crossing over, which allows survival in instances of ecological change
D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population
Answer:
D
Explanation:
Ya que en todas las definiciones anteriores el contenido que poseen no son acordes a la reproducción asexual , en otras palabras no tiene sentido alguno

What is the function of the surface protein on the influenza virus?
A To protect
B To attach to a host cell
C To manufacture enzymes using a host's immune system
D To remove a host cells's DNA
Surface proteins are the proteins that are embedded in the cell membrane structure of organisms and help in cell interaction with the outer surrounding or other cells.
Surface protein on the influenza virus is needed for attaching to the host cell.
The surface protein of viruses can be explained as:In viruses, the genetic material is stored in these protein structures called capsids which protects the viral genetic material from degrading enzymes and other cellular enzymatic activities.Surface proteins on the viruses are needed to penetrate and attach to the host system and cells for inducing immune response and diseases.The surface proteins of influenza virus HA and NA are necessary for penetrating host mucus layers.Therefore, option B to attach to the host cell the surface proteins are needed.

The seed capsules of the Himalayan balsam plant explode when touched and can eject seeds as far as 16 feet from the parent plant. Is this a structural adaptation, behavioral adaptation, or both?
Answer:
behavioral adaptation
Explanation:
A structural adaptation is defined as the adaptation in which physical features of organisms or plants while behavioral adaptation is defined as the activities an organism or plant do to survive.
The Himalayan balsam plant is an example of behavioral adaptation because it disperse its seeds when it ripe and touched by someone, for its survival it shows it dispersal behavior and spread seeds as far as 16 feet from the parent plant. In the fear of someone can harm by touching it, the survival instinct of balsam plant shows behavioral adaptation.
Hence, the correct answer is " behavioral adaptation".

Which kind of energy does this facility harness?

Answer:
A) Gravitational potential energy of water
Two plants were being tested for growth. Both were given water and proper soil, etc. However, one was placed in the closet, and one was placed in the window sill. Why did the one in the closet die? Question 4 options: It was not around other plants. It was not around people enough. It did not receive sunlight. It did not have chloroplasts.
Answer:
It did not receive sunlight
Explanation:
For photosynthesis to occur, there is a chemical equation it follows
carbon dioxide + water + sunlight -> (yields) glucose + oxygen
This equation requires the sun to create glucose. The sun provides the energy for the plant to feed itself and grow.
