Answer:
For Question 9 I'm not sure if you were taught in class but there is a chart to use called a Punnett square.
Explanation:
So for Question 9 use a Punnett square. Then Question 10 should be something about the mixture because since its a black and tan cat being mixed to make a tabby patterned cat you have to in your own words describe the mix. Hopefully this helps good enough.
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.
Answer:
B is the ANSWER!

Woo yeah thats the answer for ya'
Because the others are facts and that little guy is an opinion!

Have a radical day dude bro!
.Answer:
Option A, fix nitrogen inside nodules on the roots of legumes
Explanation:
Rizhobium bacteria live in symbiotic relationship with roots of leguminous plants such as pulses including alfalfa, soybean etc.
Rhizobium or Bradyrhizobium is a gram negative bacteria that satisfies the nitrogen starvation of host plant.
These bacteria get habitation and nutrition from these leguminous plants and in return they fix the nitrogen into the nodules of the roots. This is a kind of facultative association between soil bacteria rizhobium and legume plants.
Hence, option A is correct
Thus, option A is correct
