Answer:

4.5 billion years ago

Earth hasn't always been a blue and green oasis of life in an otherwise inhospitable solar system. During our planet's first 50 million years, around 4.5 billion years ago, its surface was a hellscape of magma oceans, bubbling and belching with heat from Earth's interior.

Giardia does it lead to elevated levels of IgE and eosinophilia?
vaieri [72.5K]

Answer:

No, Giardia is a protozoan that does not cause eosinophilia.

Explanation:

Eosinophilia refers to an increase in the number of eosinophils in the blood. The eosinophil is one of the white blood cells. When this occurs, the circulating eosinophils might be over 400 or 500.

Many factors might cause. One of them is parasite infections, in which helminths trigger the IgE generation, producing eosinophilia.

In the presence of the parasite antigen, eosinophils have a shorter medullar generation time, and they express a higher number of receptors for IgE and IgG. Their function is to damage the parasite, directly or indirectly, and to decrease the damages caused by their presence.

Giardia, among other protozoans, does not cause eosinophilia. Yet some other protozoans and parasites might induce it.

Would a nerve cell and a blood cell from a human contain the same DNA
Readme [11.4K]

Every cell of the body contains the same DNA. So, the nerve cells and the blood cells have the same set of genetic instructions.

Different cells are produced by differential use of that DNA. Different sets of genes must be turned on and off in the various cell types (differently expressed genes).

Most cells in a human body contain a complete set of the genome <span>( the genetic material of an organism), which is two sets of 23 chromosomes, with exception of egg and sperm cells, which carry only half a set of chromosomes (23 instead of 46).</span>

The P(O₂) in the tissue cells is ____________ mm Hg. The blood as it enters the surrounding systemic capillaries has a P(O₂) of
PIT_PIT [208]

Answer: 40 mm Hg,  95 mm Hg, out of, down

Explanation:

In tissue cells the P(O2) is 40 mm Hg. The blood as it reaches the systemic capillaries around it has a P(O2) of 95 mm Hg. Hence, oxygen diffuses into the cells from the systemic capillaries down the partial pressure gradient. The carbon dioxide diffuses in the same direction at the same time.

Hence, the blanks will be filled with 40 mm Hg,  95 mm Hg, out of, down.
