Fusion and gravity
Fusion and gravity keep the sun from blowing itself up. A large amount of energy is released by the
sun. Protons are fused together to form helium atoms due to the high heat and
pressure at the center of the sun. The Sun does not blow itself up from the
outer pressure of nuclear fusion in as much as the inner force of gravity
balances it.
50% because they would produce two Rr.
Answer: Global warming is happening because the greenhouse gases are becoming more thicker which makes more of the suns radiation (heat) stay in the earth; as a result, this is increasing the earth's temperature.
The subject is geography :)
Explanation:
Answer:
The correct answer is the endocrine system.
Explanation:
The sympathetic division of the autonomic nervous system and the endocrine system are the two prime systems that take part in the stress response.
At the time of acute or chronic stress, the endocrine system first makes the hypothalamus to discharge CRH or corticotropin-releasing hormone into the bloodstream. The release of CRH further makes the anterior pituitary to discharge ACTH or adrenocorticotropic hormone into the blood. This further stimulates the adrenal cortex to discharge cortisol, that is, one of the glucocorticoid hormone into the bloodstream.
The cortisol finally makes the organs and tissues present within the body to effectively cope up with the initial stress stimulus.
Answer:
Mrs Jones Blood type= B type.
Safe transfusion from: B and O blood type.
Explanation:
In the given example, the anti-B antibodies are present in the donor plasma. Since anti-B antibodies react with B antigen present on the RBCs of blood, Mrs. Jones should have B antigen on the surface of her RBCs. The blood type with only B-antigen on the RBC's surface is blood type "B".
Hence, her blood type is "B" type which has B antigens that react with anti B antibodies of the donor plasma causing agglutination and hemolysis of RBCs.
She can get the blood of B and O blood types. Blood type O is a universal blood type as it does not have B or A antigens on the surface of its RBCs to initiate the agglutination.
