What are three important functions of the cell membrane?
Answer:
Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment; and (3) they separate vital but incompatible metabolic processes conducted within organelles.
Answer:(1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment; and (3) they separate vital but incompatible metabolic processes conducted within

Answer:
A - the four cells have identical DNA sequences.
Explanation:
Essentially all cells in a multicellular organism have exactly the same DNA sequence.
The reason the cells look different is because different genes are active in different cells - which gives them their unique shapes, structures and activities!

what is the difference between involuntary muscles and voluntary muscles
Answer:
Voluntary muscles or striated muscles are those which are in our control.
ex, biceps, triceps, upper part of oesophagus., tongue.
On the way, the involuntary or non striated muscles are those which are not in control.
Ex, full ice of blood capillaries.
For what type of organism is the carrying capacity shown?
Answer:
I'm pretty sure it's white tailed deer, since that's what the graph is describing and showing the carrying capacity for.
White tailed deer has the carrying capacity in the graph.
What is carrying capacity ?The carrying capacity of any organism can be defined as the maximum population size of the species in a sustainable environment indefinitely up to the limit no further growth.
Carrying means to support and Capacity refers to the ability to reproduce the maximum output, when population reaches the carrying capacity then the mortality will be greater than natality.
The importance of Carrying capacity is mainly based on concept of sustainability, environmental imbalances and Global warming is also causative agent, eradication of poverty and provision of the traditions, practices are also enhance the carrying capacity importance.

Which of the follow categories of organic molecules is correctly paired with one of its functions?
A. carbohydrates-store genetic information
B. nucleic acids-digest dead cells
C. proteins-provide structure in skin, hair, and nails
D. lipids-give quick energy cells
Answer:
C
Explanation:
Carbohydrates are for energy storage
Nucleic acids store genetic information
Proteins provide cell structure
Lipids are for long term storage
The amino acids needed to form keratin, one of the structural proteins in our skin, hair, and nails, are provided by protein to the body. You must ingest a suitable amount of protein as well as particular vitamins and minerals that help your body produce keratin naturally. Thus option C is correct.
What role of protein in structure formation?Proteins are the structural and motor components of the cell and operate as the catalysts for almost all biochemical reactions that take place in living things, making them the cell's workhorses.
A protein called keratin aids in the formation of your skin's outer layer, hair, and nails (epidermis). Your skin is supported, wounds are treated, and your hair and nails are kept in good condition. Your body contains 54 different varieties of keratin.
Therefore, proteins-provide structure in skin, hair, and nails.

Cellulose and starch are examples of which of the following?
A. disaccharides
B. lipids
C. monosaccharides
D. polysaccharides
Answer:
D
Explanation:
Monosaccharides are simple sugars, whereas cellulose and starch are not. They have many sugars, and therefore are polysaccharides.
Cellulose and starch are examples of polysaccharides.
what are the properties of polysaccharides ?Polysaccharides are made up of more than two sugar molecules, these are long chains bio-macromolecules act as an important source of energy in animal cell and form a structural component of a plant cell wall.
It can be up two types such as homopolysaccharide and heteropolysaccharide based on the composition of the type of monosaccharides.
If the Polysaccharides is a straight chain known as linear polysaccharides, if it is branched known as a branched polysaccharide.
Polysaccharides not sweet in taste, insoluble in water, hydrophobic, extracted to form a white powder, high molecular weight, compact and osmotically inactive, consist of hydrogen, carbon, and oxygen.
They store energy, water cannot invade the molecules making them hydrophobic, influences the uptake of nutrients and water by the cells, provide support to the cells.

What type of genetic material does a Blue whale contain?
Answer:
The blue whale is very genetically diverse. There are four subspecies of blue whale: B. musculus musculus, B. musculus intermedia, B. musculus indica, and B. musculus brevicauda. Very little is known about the genetic differences between these species besides appearance and weight. The subspecies don’t usually mix because of location.
In the 19th and early 20th centuries, almost all of the blue whales were killed for their baleen plates. They are now increasing in population, and scientists would like to try to see what they can do to continue to increase the population.

describe how an amino acid molecule passes from the lumen of the ileum to the liver
Answer: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides.
Explanation: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides. They are then transported across the alabaster membrane via facilitated diffusion. Di and tripeptides are absorbed via separate H+ dependent cotransporters and once inside the cell are hydrolyzed to amino acids.
Amino acid molecule passes from the lumen of the ileum to the liver
through Sodium cotransporter.
The protein first of all hydrolyzed into amino acids through the enzymes
gastric and pancreatic proteases.
Amino acids are absorbed from the lumen of the ileum to the liver through
the cotransporter. This is done by it moving through the alabaster
membrane through the mechanism called facilitated diffusion and
subsequent absorption through H+ dependent cotransporters.

What type of membrane protein has a
straight pathway for molecules to move?
A. Channel protein
B. Carrier protein
C. Receptor protein
D. Glycoprotein
Answer: C
This membrane protein is a receptor protein. Polytopic membranes cross the membrane for the molecules a couple times. The answer is C.
Hope it helps!
The type of membrane protein that has a straight pathway : ( C ) Receptor protein
Receptor protein binds ligands molecules outside a cell after which it changes its conformation and transmits signal from the molecules through molecular switches into the cell ( via the signal pathways of the cell ).
The process of binding ligand molecules, transmitting signals into the signal pathways of the cell follows a straight pathway for the movement of molecules.
Hence we can conclude that the type of membrane protein that has a straight pathway for molecules to move is Receptor protein.

Male pine cones contain:
soft scales
a sticky fluid
sperm tubes
pollen sacs
Answer:
Male cones are a lot smaller than female cones and their scales aren't as open. Each scale in a male cone contains the pollen that can spread to a female cone to make a seed.
Explanation:
I don't know what you are asking but that is my answer.....be more specific.
Answer:
Male pine cones have a sticky fluid, sperm tubes, and pollen sacs.
Explanation:
Both male and female pine cones have sperm tubes, but only females have soft scales. Male cones have rough scales that let the pollen in and out of it. Although female cones soft scales, they still allow pollen to enter into the cones. The pollen that goes into the female pine cone never gets out, though.
