what are the functions of the kidney

Answers

Answer 1
Basic Functions
The kidneys are essential for homeostasis (maintaining a constant internal environment) of the body's extracellular fluids. Their basic functions include:
1. Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.

2. Regulation of osmolarity. The kidneys help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid.

3. Regulation of ion concentrations. The kidneys are responsible for maintaining relatively constant levels of key ions including sodium, potassium and calcium.

4. Regulation of pH. The kidneys prevent blood plasma from becoming too acidic or basic by regulating ions.

5. Excretion of wastes and toxins. The kidneys filter out a variety of water-soluble waste products and environmental toxins into the urine for excretion.

6. Production of hormones. The kidneys produce erthryopoietin, which stimulates red blood cell synthesis, and renin, which helps control salt and water balance and blood pressure. They are also involved in regulating plasma calcium and glucose levels.

nucleic acids are assembled in the _____ direction.

Answers

5’ to 3’ hope this helps:)

Nucleic acids are assembled in the 5' to 3' direction during DNA replication. DNA replication is the process of duplication of DNA molecule.

What are Nucleic acids?

Nucleic acids are the biomolecules occurring in the chemical compounds which serve as the primary information-carrying molecules in the cells. Nucleic acids play an important role in directing the process of protein synthesis. The two main classes of nucleic acids include deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Nucleic acids can only be synthesized in vivo in the 5′-to-3′ direction and these can be assembled in the same direction in cell, as the polymerases which assemble various types of new strands generally rely on the energy which is produced through breaking the nucleoside triphosphate bonds to attach these new nucleoside monophosphates to the 3′-hydroxyl (−OH) group, through a phosphodiester bond.

Tại sao con người chúng ta lại sốt nhiều lần như vậy?

Answers

Answer:

Fever is an elevated temperature of the human body that is substantially beyond the normal range. Normal body temperature fluctuates daily from about one degree below 98.6 degrees Fahrenheit to one degree above that number. Lower body temperatures usually occur before dawn; higher temperatures in the afternoon.

Body temperature also varies slightly depending on where on the human body it is measured. Rectal (internal) temperature tends normally to be higher than skin (surface) temperature. Oral and armpit temperatures can approximate actual body temperature and are more convenient to measure.

Skeletal muscle exhibits alternating light and dark bands called a sarcomere

Skeletal muscle is having sarcomere having myofibrils which appear dark and light in the microscope.

What is skeletal muscle?

Only thin filaments containing actin are present in isotropic bands, anisotropic bands are the darker bands (A bands).

Repeating sarcomere sections, which are visible under the microscope as alternating dark and light bands, make up myofibrils.

When a muscle contracts or relaxes, long, fibrous protein filaments called sarcomeres glide past one another. Because of this, skeletal muscle is also known as striated muscle.

Therefore in appearance due to myofibrils composed of the sarcomere look light and dark bands in the skeletal muscle under a microscope.

Answer:

examining the tusks, bones, teeth, (carbon levels in tissues depends)

Explanation:

Carbon-14 can be used to date the remains of dead organisms because all living things use carbon to build tissue.

The biological age of mammoths (also known as the "age at death") is usually estimated by comparison to correlations between the biological age and the wear stages of grinding teeth in extant elephants. As tusks grow, they continually incorporate ingested strontium (Sr), and the incremental record of strontium isotope ratios (87Sr/86Sr) in tusks and teeth can be used to investigate proboscidean movements
