Answer:

The procedure by which a star modifies with the course of time is known as the stellar formation or evolution. The following is the arrangement of events of the earliest stellar formation:  

1. The phenomenon of Big Bang taking place.  

2. In higher concentrations, the pockets of elements start to experience greater gravitational force.  

3. The shedding of electrons takes place by hydrogen atoms and combines together to produce bigger helium atoms.  

4. The volume of the glass clouds starts to reduce and results in the upsurge of pressure, density, and temperature.

Answer;

Arrangement of events in stellar formation;

C) The Big Bang occurs.

B) Pockets of elements in higher concentrations begin experiencing greater gravitational force.

A) Hydrogen atoms shed their electrons and fuse together to form larger helium atoms.

D) the glass clouds begin reducing in volume, which leads to increase in density, pressure, and temperature.

Explanation;

-Stellar evolution is the process by which a star changes over the course of time. All stars are born from collapsing clouds of gas and dust, often called nebulae or molecular clouds.

-Stars are born out of the gravitational collapse of cool, dense molecular clouds. As the cloud collapses, it fragments into smaller regions, which themselves contract to form stellar cores.

Egg membranes from three eggs were carefully taken out and labeled as a, b , c. Each of these membranes were filled with 1% solu
Readme [11.4K]

Answer:

The correct answer would be -

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

Explanation:

This experiment deals with tonicity as this solution will affect the tonicity of the egg membrane. In membrane A there are more solutes inside the cell than outside the cell so it is hypotonic solution so the movement of water will be towards inside the cell.

In membrane B the solutes are equal in both sides so there will be no movement as its isotonic condition while in membrane C the solution is in hypertonic situation as the solutes are more outside than inside.

Thus, the behavior of the membranes are-

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

Write all possible codons recognized by each of the given anticodons. An anticodon strand reads 5'–GCG–3'. Fill in the missing b
gregori [183]

Answer:

Codon: 3'-CGC-5'

Codon: 3'-UGC-5'

Explanation:

The anticodons of tRNAs bind to the complementary codons of mRNA. The mRNA codons are always read in 5' to 3' direction. The 5' base of an mRNA codon pairs with 3' base of the anticodon of tRNAs. The first base of the anticodon (the  5' base) determines the number of mRNA codons that are recognized by the tRNA. When the 5' base of the tRNA anticodon is U or G, it binding with codon is less specific. A tRNA anticodon with 5’ G base can read two different codons.  

Anticodon:  5'–GCG–3'.

Codon: 3'-CGC-5'

Codon: 3'-UGC-5'

il63 [147K]

Answer: The pathology described in the question is "testicular torsion".

The most sensitive physical exam that is specific to this pathology is testing for reflexes. The inner thigh of the affected side when rubbed should cause the testicle to contract; but in this pathology, it does not.

Explanation:

Testicular torsion is a condition caused by the twisting of the spermatic cord, which causes a loss of blood flow to the testicle. It is the leading cause of testicular loss in adolescent boys, if no surgical intervenvention is carried out as soon as possible.
