Prokaryotic cells lack membrane enclosed cell structures.
What are the characteristics of prokaryotic cells?Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles.
Examples of prokaryotes are blue-green algae, bacteria and mycoplasma. Among prokaryotes, bacteria are the most common and multiply very fast.
They lack a nuclear membrane. Mitochondria, Golgi bodies, chloroplast, and lysosomes are absent. The genetic material is present on a single chromosome. The histone proteins, the important constituents of eukaryotic chromosomes, are lacking in them.

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.

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.
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.
