Erythrocytes, neurons, skeletal cells, and columnar cells are examples of: specialized cells. cell, in biology, the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes. There are many unicellular organisms, e.g., bacteria and protozoans , in which the single cell performs all life functions. In higher organisms, a division of labor has evolved in which groups of cells have differentiated into specialized tissues , which in turn are grouped into organs and organ systems. Cells can be separated into two major groups—prokaryotes, cells whose DNA is not segregated within a well-defined nucleus surrounded by a membranous nuclear envelope, and eukaryotes , those with a membrane-enveloped nucleus. The cyanobacteria and bacteria (kingdom Monera ) are prokaryotes. They are smaller in size and simpler in internal structure than eukaryotes and are believed to have evolved much earlier (see evolution ). All organisms other than cyanobacteria and bacteria consist of one or more eukaryotic cells. All cells share a number of common properties; they store information in genes made of DNA (see nucleic acid ); they use proteins as their main structural material; they synthesize proteins in the cell's ribosomes using the information encoded in the DNA and mobilized by means of RNA; they use adenosine triphosphate. as the means of transferring energy for the cell's internal processes; and they are enclosed by a cell membrane, composed of proteins and a double layer of lipid molecules, that controls the flow of materials into and out of the cell.

When muscle cells have more glucose than they need for energy, they may store some of the excess as?

ddd [48]

I think the answer is glycogen.Glycogen functions as one of the two forms of long-term energy reserves, with the other form being triglyceride stores in adipose tissue. In human body, glycogen is made and stored primarily in the cells of the liver and skeletal muscle. In the muscles it is the primary fuel the muscles use for energy production.

During cellular respiration, most ATP is formed as a direct result of the net movement of

miv72 [106K]

Answer:

protons against a concentration gradient.

Explanation:

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Hence, during cellular respiration, most adenosine triphosphate (ATP) is formed as a direct result of the net movement of protons against a concentration gradient in the electron transport chain.

Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

An individual is the genotype Gg for a height trait. This individual is ________________ for that height trait.

andreyandreev [35.5K]

This individual is heterozygous dominant for that height trait.

Explanation:

In Mendelian Genetics the letters in uppercase are for dominant traits and those in lower case are for recessive trait.

An individual has 2 alleles for a gene one from either parent. The dominant allele express the phenotype according to the law of dominance. Individual could be either heterozygous that is both the dominant and recessive traits' allele are present in its gene or homozygous dominant in which both the alleles are dominant.

eg: GG (dominant homozygous)

Gg (Heterozygous dominant)

The individual with genotype Gg for a height will have dominant allele expressed which will mask the effect of recessive gene. The phenotype will be of dominant trait.
