If a star of 50 solar masses were to supernova. It would most likely become a black hole.

A star is a hot body of glowing gas which starts its life in Nebulae. The stars vary in size, mass and temperature. The mass of a star ranges from 1/20 times to 50 solar mass.

The stage one of the stars is born in nebula, which is a region of very high density and then it gets condensed to a huge globule of gas and dust that contracts under its own gravity.

The next stage is a region of the condensing matter which starts heating up and glowing is known as Protostar. At stage three, hydrogen fuses and forms helium as the nuclear reactions start. Stage four is a Main Sequence star when it starts to release its energy, contraction stops and it begins to shine.

Some of the stars have mass more than 3 times of the Sun and up to 50 times the mass of the sun.

When the surviving core is between 1.5-3 solar mass, with higher contraction making it tiny and dense a Neutron star is formed. If the core is greater than 3 solar masses then the core further contracts to become a Black Hole.

Suppose an alkane had 8 carbon atoms. How many hydrogen atoms would it have? a. 18 atoms c. 10 atoms b. 16 atoms d. 12 atoms

Delvig [45]

<h3>Answer;</h3>

A. 18 hydrogen atoms 

<h3>Explanation;</h3>

Alkanes are group of hydrocarbon that are saturated. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.
Therefore, an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. Thus, the formula of the hyrocarbon will be; C₈H₁₈.

Frogs have lungs for breathing, but they also absorb dissolved oxygen directly through their skin. This allows respiration to oc

alukav5142 [94]

Answer: B. Water breaks down into oxygen molecules for respiration.

Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.

$6CO_2\ \ \ \ +6H_2O\rightarrow\ C_6H_{12}O_6+6O_2\\carbon\ \ \ \ water\ \ \ \ \ \ \ \ glucose\ \ \ \ \ \ \ oxygen\\ dioxide$

This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.

Which describes an oxidation reaction that occurs during cellular respiration?

Yuri [45]

Answer: Option 4; Oxygen gains electrons and hydrogen to form water.

Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.

Since, oxygen is consumed during respiration, option 1 is incorrect.

Loss of electrons is reduction, so option 2 is also incorrect.

Glucose is used in respiration, thus option 3 is incorrect.

What makes angiosperm more advance than gymnosperm

USPshnik [31]

Answer& Explanation:

Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).

1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.

2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.
