Where are your blood cells made

1 answer:

6 0

Red blood cells. Red blood cells (also known as erythrocytes) are cells in the blood that carry oxygen to all parts of the body. They are made in the spongy marrow inside the large bones of the body. Bone marrow constantly makes new red blood cells to replace old ones.

. In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water, and contains proteins, glucose, mineral ions, hormones, carbon dioxide, and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells, white blood cells and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is mostly transported extracellularly as bicarbonate ion transported in plasma.

Which of the following statements about RNA polymerase in transcription is correct? RNA polymerase is an enzyme that synthesizes

emmainna [20.7K]

RNA polymerase, also known as DNA-dependent RNA polymerase, is an enzyme that produces primary transcript RNA. In cells, RNAP is necessary for constructing RNA chains using DNA genes as templates, a process called transcription.

As I stated RNA Polymerase is a Enzyme. So your answer would be A. :)

Hope I helped. :) Thanks or using Brainly.

Match each hazardous waste with its matching description.

Sphinxa [80]

Matching each hazardous waste with its description is shown below :

Hazardous waste description

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead : Substance from thermostats known to cause reproductive issues

Too much exposure to these hazardous waste always leave a negative effect on the health of individuals, Asbestos are used in the roofing of older buildings and can be found in older landfills. the fiber from asbestos affects the Lungs ( alveoli ) of humans which might lead to lung cancer.

Mercury are used for PC's backlight and also in the mother board of modern computers too much exposure to mercury can lead to brain damage.

Cadmium are hazardous cancer causing agent used in making industrial batteries, prolonged exposure to lead poses several health risk which includes reproductive issues because lead can cut across placenta barrier between a pregnant woman and unborn child.

Hence we can conclude that matching each waste to its description is as

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead : Substance from thermostats known to cause reproductive issues

Seismic gaps are places where scientists think that ________.

Elis [28]

The answer is Faults are storing elastic strain. To simplify, seismic gaps are places where scientist think that faults are keeping elastic strain. In addition, scientists think that stress on a fault constructs up to a critical point and is then unconstrained as an earthquake. The seismic gaps are areas in which no earthquakes have occurred over a long period of time and therefore are probable to be under a high volume of stress.
