what is cytoplasm?? what is a cell??
Answer:
Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm. A Cell in biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and controls the substances that go into and out of the cell. The basic unit of a living organism.

The Fish ingests carbon dioxide from the hydrosphere and stores the carbon for later use ( C ) The crab expels carbon dioxide into the hydrophere when glucose is converted into ATP ( D ) Organisms in the food chainOrganisms in the food chain contribute greatly to the flow of carbon in the atmosphere by consuming, storing and expelling carbon in variuos form to help regulate the flow of carbon in the carbon cycle. Algae use carbon dioxide during photosynthesis to produce glucose which is stored for use. also as the crab ingests snails and other marine organisms it stores the carbon for use as a source of energy.

DNA sequences that cap chromosomes, known as ______, become shorter and shorter each time a cell divides; and after about 70 or 80 such divisions, they are dramatically reduced, and the cell can no longer reproduce.
Telomere is the DNA sequence that cap chromosomes and it become shorter each time a cell divides.
What are Telomeres?Telomeres are DNA sequence that cap chromosomes and are made up repetitive sequences of non-coding DNA which help to protect the chromosome from been damaged. Anytime, a cell divides, the telomeres become shorter and continue to become so short that the cell can no longer divide.

A student has twenty identical young plants how does the amount of water given to these plants each day effect how tall the plant will grow
Answer:
The amount of water given to the plants depends on the effect of how tall the plant can overall grow. For instance, if all twenty identical plants are being given the same amount of water, then they will grow all at equal rates. However, if there is not equal amount/consistency with the amount of water the plants receive, then this factor may contribute to an uneven growth pattern between all twenty plants. However, other factors (such as location, sunlight, etc.) may also contribute to a plant's growth.
It can be inferred from the graph above that the decreasing water levels in Walker Lake are caused by the creation of reservoirs. Which of the following is evidence from the graph that shows the effect decreased water levels have had on the lake?
A:The dissolved solid concentration is increasing.
B:The graph does not show evidence of any effect decreased water levels are having on the lake.
C:The water temperature is rising.
D:The fish population is decreasing.
The dissolved solid concentration increasing is the evidence which shows the effect decreased water levels have had on the lake.
What is Concentration?
This is defined as the ratio of the solute to the solvent or the total solution. A lake comprises of a solution with different solutes and solvent which is water.
When the water levels in the lake decreases, the solid concentration increases which is why option A was chosen.

The urine-collecting structures found within the kidney are:
Renal pyramidsMinor calyxMajor calyxRenal pelvisUreterWhat are Urine-collecting structures?The urinary system includes the systems that collect and carry urine from the kidneys to the bladder for removal from the body. Renal pyramid, minor and major calyces, renal pelvis and ureter are some of these structures.
1. The renal medulla contains triangular-shaped structures called renal pyramids, which are filled with urine-collecting tubules.
2. Minor calyx: These are small, cup-shaped organs that collect urine from the collecting ducts of the pyramids of the kidneys.
3. Major calyx: These are large, cup-like structures that form when several smaller calyces come together. They receive urine from the corpus luteum as they empty into the renal pelvis.
4. The ureter, which carries urine to the bladder, receives urine from the main calyces, a funnel-shaped structure in the renal pelvis.
