what is the function of a membrane protein
Answer:
Membrane proteins can allow hydrophilic molecules to pass through the cell membrane.
Explanation:
Answer:
Explanation:
Membrane proteins are common proteins that are part of, or interact with, biological membranes. Membrane proteins fall into several broad categories depending on their location. Integral membrane proteins are a permanent part of a cell membrane and can either penetrate the membrane (transmembrane) or associate with one or the other side of a membrane (integral monotopic). Peripheral membrane proteins are transiently associated with the cell membrane.
The modern cell theory doesn't say
A all living things are multicellular
B cells are the smallest living unit in all organisms
C all cells come from other cells
D all living things are made of cells
Answer:
A
Explanation:
Modern cell theory states: cells are the basic unit of structure and function for all living things, all cells come from preexisting cells, and all living things are made from cells. It does not state that all living things are multicellular, in fact there are plenty of unicellular organisms. Therefore the answer is A.

The following chemical equation shows the combustion of ethane. Balance the equation by filling in the coefficients.
Answer:
2 C2H6 + 4 O2 → 2 C + 2 CO2 + 6 H2O
Explanation:
2 C2H6 + 4 O2 → 2 CO2 + 6 H2O is the balance equation for the combustion of ethane. In the question, the equation for combustion of methane is unbalanced i. e. C2H6 + O2 → CO2 + H2O so by putting coefficient 2 in front of ethane, 4 in front of oxygen, 2 in front of carbondioxide and 6 in front of water which can balance the unbalanced equation for combustion of ethane
The text box below contains facts about salmon:
juvenile salmon migrate from freshwater streams and rivers to the ocean.
in the ocean, juvenile salmon d.r.i.n.kk. salt water.
Special cells on the salmon's gills called chloride cells help the salmon to excrete salt.
How do populations of juvenile salmon respond to changes in salinity as they migrate?
The juvenile salmon utilize special structures but do not alter their behavior.
The juvenile salmon alter their behavior and utilize special structures.
The juvenile salmon utilize special structures to alter their behavior.
The juvenile salmon alter their behavior but do not utilize special structures.
Answer:
due to the salmons body and biology the salinity doesnt matter because they can change whats around them using the salt from inside their body
Explanation:
they both utilize and alter behavior
The populations of juvenile salmon respond to changes in salinity as they migrate the juvenile salmon utilize special structures to alter their behavior. Therefore, option C is correct.
What is salinity ?The amount of dissolved salt in a body of water is known as salinity. It makes a significant contribution to conductivity and influences many aspects of the chemistry of natural waters as well as the biological activities that take place there.
In soils and seas, primary salinity is a natural occurrence. Salt lakes, salt pans, salt marshes, and salt flats are a few examples of naturally occurring salty landscapes. Salting caused by human activity, typically land development and agriculture, is known as secondary salinity.
Salinity is the buildup of salt to a degree that harms the built environment and the ecosystem in general. While there are many areas of the Australian terrain that are naturally salty, human activity has the potential to raise salt levels. Water and salinity go hand in hand.
Thus, option C is correct.

A new trait that was never in the gene-pool before is called a
A) Adaptation
B) Mutation
C) Genetic Variation
D) normal
Answer:
B) Mutation
Explanation:
Mutation is a mistake in the Gene's I doesnt mean it's a bad thing or a good thing. It could be both
What practice helps scientists avoid bias in their findings
Many bacteria, including E. coli, are capable of growing under both anaerobic and aerobic conditions. Some mutations are introduced into an E. coli strain that inactivate several enzymes involved in DNA repair. The mutant strain grows normally when kept in an incubator with a 100% nitrogen gas atmosphere. However, the strain dies when exposed to a normal laboratory atmosphere. Why
Answer:
Due to inability to survive in aerobic condition.
Explanation:
The strain dies when exposed to a normal laboratory atmosphere instead of nitrogen gas atmosphere because the mutation causes change in the capability of the strain to survive in the aerobic conditions. This mutation inactivate several enzymes which is also responsible for their capabilities of surviving under both anaerobic and aerobic environment so that's why the strain dies when exposed to normal atmosphere..
An inflated basketball hold 6 liters of air at 3 ATM. How much air at 1 ATM went into the ball
Answer:
18 litres
Explanation:
Using Boyle's law equation as follows:
P1V1 = P2V2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (litres)
V2 = final volume (litres)
According to the information in this question, An inflated basketball hold 6 liters (V1) of air at 3 atm (P1). The volume of air (V2) at 1 atm (P2) that went into the ball can be calculated thus:
Using P1V1 = P2V2
3 × 6 = 1 × V2
18 = V2
V2 = 18 litres.

You perform an experiment in which chromatin is isolated from sea urchin sperm cells and briefly digested with micrococcal nuclease. When the chromatin proteins are removed and the resulting purified DNA is analyzed by gel electrophoresis, you observe a series of DNA fragments that are multiples of 260 base pairs in length (that is, 260 bp, 520 bp, 780 bp, and so forth). a) Although these results differ somewhat from the typical results discussed in the chapter, explain why they still point to the likely existence of nucleosomes in this cell type. b) What can you conclude about the amount of DNA that is associated with each nucleosome
Answer:
a) DNA fragments associated with histone proteins are all multiple in length (i.e., 260 bp, 520 bp, 780 bp, etc), thereby suggesting the presence of a pattern of organization in the chromatin
b) it suggests that each unit of organization (ie, each nucleosome) consists of 260 bp associated with chromatin proteins
Explanation:
The nucleosome is considered as the basic unit of chromatin. A nucleosome consists of approximately two turns of DNA wrapped around a core of eight histone proteins (i.e., a histone octamer). The histone octamer consists of two copies of each of the histones H2A, H2B, H3, and H4. Moreover, the nucleosomes are connected together by linker DNA sequences which vary between 10 and 100 bp in length.

Glucose is a large molecule that is transported across the cell
membrane through a gated channel, a type of transport protein
used during what
diffusion
The type of transport protein used during glucose transportion across the cell membrane is facilitated diffusion.
Glucose is the main energetic substrate of the cell and requires a transporter protein in the cell membrane for its entry.
Proteins found on the surface of the membrane intervene in facilitated diffusion, which, when they make contact with the molecules, bind to them and allow their entry.
This route is used by molecules that are larger in size, with properties other than the membrane (polar), or are charged and do not cross the membrane freely; for example glucose.
The transport of glucose across the cell membrane is carried out by two families of membrane proteins:
Sodium-coupled glucose transporters are expressed mainly in epithelia that are responsible for the absorption and reabsorption of nutrients.Glucose transporter (GLUT) are expressed in all cells of the body and allow glucose to move from one compartment to another.
Therefore, we can conclude that glucose enters cells through facilitating transport systems, glucose transporter are expressed in all tissues of the organism and transport glucose through its concentration gradient, hence the name of facilitated diffusion.
