an experiment

A convincing explanation of why some lineages survived while others vanished is still lacking in the hypothesis of an asteroid impact as the cause of the end-cretaceous mass extinction.
<h3>What is an
asteroid?</h3>
One of the smaller planets in the inner Solar System is an asteroid. Asteroids are metallic or rocky bodies without an atmosphere, ranging in size from 1-meter pebbles to a dwarf planet with a diameter of over 1000 km.
The majority of the one million or more known asteroids are concentrated in the main asteroid belt, which is 2 to 4 AU from the Sun and between the orbits of Mars and Jupiter. The three categories of asteroids that are typically recognized are C-type, M-type, and S-type.
These were given their names and are frequently associated with, respectively, carbonaceous, metallic, and silicaceous compositions. The largest asteroid, Ceres, has a diameter of over 1,000 km (600 mi), making it a dwarf planet.

Answer:
Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom, she is XO.
Explanation:
Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.
It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.
However, such mutant (X) communicates and expresses itself and she is hemophilic.
This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.
Answer:
They use a gene modification technique called CRIPSR-CAS9. The pigs have been given a gene that allows them to better regulate their own body temperature, whereby they burn fat, or at which animals consume their own fat.
Explanation:
British and Chinese scientists explained that they conducted the study by adding a mouse version of the UCP1 gene used for porcine embryos, which is used to regulate body temperature characteristic of most mammals, but not ordinary pigs.
It is problematic for pigs to maintain a stable body temperature, and this is especially complicated in pigs that are cold in the winter months because they have not been able to "store" fat.
Inserting the UCP2 gene could solve this problem.
