Answer:
Gas cloud 1: It spreads with a greater volume and less concentration of elements. Its temperature stays well below the 14 million Kelvin. It has hydrogen atoms that retain there electrons.
Gas cloud 2: Its volume shrinks and the density increase die to the gravity
. Its temperature stays above the 14 million kelvin
. Hydrogen atoms shed there electron.
Explanation:
As you already know, stars form within clouds of gas. These clouds have interstellar gases composed mainly of dust and hydrogen. When subjected to low temperatures, gases react and combine to form molecules that create clouds and continue to react until they form stars.
Cloud 1 has characteristics that show that it will form a star which are: It spreads with a greater volume and less concentration of elements, its temperature stays well below the 14 million Kelvin, it has hydrogen atoms that retain there electrons.
as we know that cloud 2 will not form stars we can say that its characteristics are: Its volume shrinks and the density increase die to the gravity
, its temperature stays above the 14 million kelvin
, hydrogen atoms shed there electron.
Answer:
True
Both polar bears and grizzly bears are genetically same species—DNA proves it. They diverged from one another about 400,000 years ago. Even today in
Answer:
moving across both the plasma membrane and the outer membrane
Explanation:
Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.
Option B
Middle colic arteries is the most likely additional source of blood to the descending colon
<h3><u>
Explanation:</u></h3>
The middle colic artery is a section of the superior mesenteric artery. Middle Colic provides the transverse colon, has a branch that runs to the right colon and branch that persists to the left colon that catches up with the left colic artery and proceeds as the marginal artery to provide the descending colon.
The left gastroepiploic artery is one of the sections of the splenic artery. Sigmoid- branch off IMA so barred in this case Splenic- proceeds of the celiac trunk, branches accumulation spleen & pancreas Superior Rectal- a sequence of IMA not possible to participate in this case
