Answer:

1. Marie Curie studied uranium radiation and measured radiation in pechblende, a mineral that contains uranium. She was the first to use the term 'radioactive'. She discovered two new elements: polonium and radium.

2. Rosalind Franklin: Through the images taken by X-ray diffraction, she made important contributions to the understanding of the structure of DNA, these images revealed the double helix shape of this, she also carried out studies on the structure of RNA, viruses, carbon and grafito.

3.Clara Barton organized the American Red Cross on May 21, 1881

4. Irene Joliot Curie did research in the field of nuclear physics and looking for the structure of the atom, particularly in the structure and projection of the nucleus. These investigations were fundamental for the discovery of the neutron. She and her husband managed to artificially produce radioactive elements

What type of energy is monitored by scientists forecasting future space weather

olganol [36]

ANSWER:

Electromagnetic energy is monitored by scientists forecasting future space weather

EXPLANATION:

Electromagnetic energy has such type of waves which propagate or radiate through space, carrying photons. Electromagnetic energy has radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays.Space weather includes any activity happening in space that might affect Eath's environment.Space weather can interrupt mobile signals,air communications and can damage our satellites.So Electromagnetic waves are monitored to control all the above situations.

Simora [160]

Most lipids are nonpolar. This property causes lipids to be water-insoluble in the bloodstream. Lipoproteins form water-soluble complexes for transport through the bloodstream by surrounding nonpolar lipids with polar phospholipids and proteins .

A central hydrophobic core of non-polar lipids, predominantly cholesterol esters and triglycerides, makes up the complex particles known as lipoproteins. Since lipids like cholesterol and triglycerides are not soluble in water, they must be carried in the bloodstream along with proteins called lipoproteins.

These lipoproteins are essential for the small intestine to absorb and transport dietary lipids, for lipids to travel from the liver to peripheral tissues, and for lipids to travel from peripheral tissues to the liver and intestine.

What are the molecules plants use in photosynthesis,

koban [17]

Sugar molecules, cells use carbon dioxide and energy from the sun to make sugar molecules. They are moved into the sieve elements (phloem cells) through active transport. Water follows the sugar molecules into the sieve elements through osmosis (since water passively diffuses into regions of higher solute concentration).

LuckyWell [14K]

The one responsible of lack of adequate saliva because of the diminished secretions of salivary glands is caused by the xerostomia. A xerostomia is symptom in which is caused by a side effect when an individual is undergoing radiation that causes him or her to have reduced or absent of the flow of saliva.
