They are ineffective against viral infections because viruses can not be treated with antibiotics.
Have a control. You have to have something to compare your experimental results or else your results could be random chance.
Answer:
1s2 2s2 2p4
Explicación:
1s2 2s2 2p4 es la configuración electrónica de la molécula de agua. En el agua, hay 10 electrones, dos de hidrógeno y ocho de oxígeno. La subcapa 2s contiene un máximo de 2 electrones, mientras que la capa 2p puede acomodar seis electrones. El átomo de hidrógeno pertenece al primer grupo y el átomo de oxígeno pertenece al sexto grupo de la tabla periódica. En la estructura de Lewis, un átomo de oxígeno está unido a dos átomos de hidrógeno en un ángulo de 104,45 grados. Existe un enlace covalente presente entre el hidrógeno y el átomo de oxígeno en el que ambos se vuelven estables. El oxígeno necesita dos electrones, por lo que forma enlaces con dos átomos de hidrógeno que tienen un electrón cada uno.
Answer:
The answer is 25%.
Explanation:
Hemophilia is a recessive illness that is x-linked.
If the husband has normal clotting ability, that means he has the dominant gene since he has only one X chromosome.
Since there is a probability that their child will have hemophilia, this means that the woman, who has 2 X chromosomes but has normal blood clotting abilities, has one dominant and one recessive hemophilia gene.
The probability that their first child will be a male is 50% and the probability that he will have hemophilia is also 50% since he will only get the Y chromosome from the father and the mother has one dominant and one recessive.
So the probability that their first child will be a son with hemophilia is 25%.
I hope this answer helps.
The correct option is (d) The early solar system had large amounts of water; so, the oldest objects in the solar system should also be abundant in water.
The statement that answers the scientific questions in the form of scientific data that supports the claim is called a scientific claim. There is need for the justification of the claim. The scientific claim here is The early solar system had large amounts of water and the justification to the claim is water is found in all the primitive bodies like the comets and the asteroids and in many dwarf planets like ceres. There are many evidences that shows that there are abundant amount of water in our solar system.
