The nucleus of the cell directs cell activity and acts like the control center. This is the place where gene activity is controlled in terms of the replication of the genes. In addition the movement and actions of the cell are also dictated from the nucleus.
Answer:
They are modified by shape, function, or size. They are made to have certain roles in different parts of our bodies. These cells group together to make/form tissues. Then these tissues make up organs that we obviously need. Different specialized cells include blood cells, nerve cells, and reproductive cells.
Explanation:
Answer:
A kilogram (kg) is stated to be 2.2 times heavier than a pound (represented as lbs). Thus, one kilo of mass is equal to 2.26lbs
The correct answer is 97761 * 2, L6050, Z44.8, Z89.11.
In the CPT index when one looks for Prosthetics/Training, then one is directed towards 97761. The code is repeated for every 15 minutes. As 30 minutes are spent in training, so 2 units are reported. In the HCPCS level II codebook when one looks for Disarticulation/Wrist prosthesis, one is directed towards codes L6050, L6055. On the basis of description, the prosthesis is reported with code L6050.
In the alphabetic index of ICD-10-CM, when one looks for fitting/device NOS/prosthetic (external), then one is directed towards the code Z44.8. In the index when one looks for the absence of organ or part (complete or partial)/wrist and hand (acquired) then one is referred towards the code Z89.11.
Answer:
Each species has a specific identifying number of chromosomes. For example, a cat, <em>Felis catus</em>, has 38 chromosomes, while corn, <em>Zea mays</em>, has 20 chromosomes each chromosome carries specific genes that are unique to that chromosome.
Explanation:
Chromosomes vary in shape and number among living beings. For example, the bacterial chromosome is a unique circular molecule, while human beings have 46 lineal chromosomes arranged in pairs (23 pairs). The total number of chromosomes is specific to each species, and it is denoted as the "chromosomic dotation" of the species.
Genes are the hereditable units that transmit the information needed to specify traits, from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.
Genes vary in size and shape. They are composed of pairs of bases, and these sequences also vary in number, producing genes of different lengths. In general, genes code for proteins. Proteins create the organism tissues and perform or carry out specific functions in the organisms, controlling almost all processes and chemical reactions.
Each chromosome carries <u>specific</u> genes that code for <u>specific </u>proteins that have <u>specific</u> functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But <u>not all chromosomes carry the same gene sequences</u>. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but different alleles.
