I believe it would be A) 8 neutrons because from what I remember a neutron is a negative charge and a proton is a positive charge and you have to have equal positive and negative charges. Don't quote me on that, I would recommend googling it for a confirmation but the answer is A. I am just not 100% on the explanation!

Digiron [165]
<span>7. which, if any, of the blood samples tested cna the patient with type b+ blood receive? explain why.
It can't be answered because you didn't put the sample test result


8. explain how you were able to use your knowledge of how different types of blood react with anti-a, anti-b, and anti Rh antibodies to determine the blood types of the four samples.
If the blood react with anti-a, then the blood must not have A antigen
</span>If the blood react with anti-b, then the blood must not have B antigen
If the blood react with anti Rh, then the blood must not have Rh antigen
Based on the antigen, you can conclude the result as:
react with anti A= blood type B
react with anti B= blood type A
react with anti A and anti B= blood type O
react with anti Rh= Rh-
not react with anti Rh= Rh+
<span>
9. if a person has type a blood, he or she would have antibodies for what blood type?
Type A blood has antigen A. So that person should not have anti-A antigens. 
The person should have anti-B antibodies because it was a foreign object to him. Depends on the Rhesus type, he can have Rh antibodies too.

10. why is type o negative blood known as the universal donor? why is o positive not a universal donor?

Type O blood doesn't have antigen-A or antigen-B. That means the blood cells won't trigger any reaction on Type A, B, AB, or O blood. Negative rhesus also means that the blood is safe for Rhesus negative or Rhesus positive type. 

Positive O blood type has rhesus antigen, so it will trigger a reaction in Rhesus negative type. </span>

¿Cómo explicaría Lamarck el origen y la expansión de estas bacterias resistentes? ¿Cómo explicaría
Anuta_ua [19.1K]

La teoría de la evolución de Lamarck se basa en la capacidad de los organismos para cambiar físicamente debido a las adaptaciones en su entorno para garantizar su supervivencia. Esto es evidente en la propagación de los determinantes de resistencia a los antibióticos entre las bacterias. La capacidad de las bacterias para desarrollar nuevos mecanismos de resistencia para sobrevivir a los antibióticos radica en su capacidad para adquirir genes que los ayuden a este respecto a través de la transferencia horizontal de genes y la adquisición de plásmidos. Mecanismos como bombas de eflujo y plásmidos les ayudan a sobrevivir en medio de antibióticos. Transmiten estos materiales genéticos a sus descendientes, lo que garantiza que continúen sobreviviendo y no se extingan a pesar de la presencia de antibióticos.

El dawrnismo claramente reclama la selección natural. Por lo tanto, si un organismo no evoluciona o adquiere características especiales para ayudarlo a adaptarse, competir y sobrevivir en su entorno, se extingue. Solo aquellos que adquieren estas habilidades sobreviven y se reproducen en el medio ambiente.

The diagram represents some stages in the 19. development of the modern horse, according to evolutionary theory. The diagram is
alexdok [17]

Hello. You forgot to add the diagram.

The diagram is attached below.

Answer:

1. examination of homologous fossilized structures of primitive horses

Explanation:

As you can see in the diagram, to show the stages of the development of the modern horse, a comparison is made between the forelimb structure and the molar tooth of these horses (related to the adult form). These two factors of comparison establish the representation of fossilized homologous structures of primitive horses.

As you may already know, homologous structures are different body structures from different animals that have a strong similarity (because they are inherited from a common ancestor). When these animals die and these structures are conserved, we can say that they have been fossilized.

As the forelimb structure and the molar tooth of the horses shown in the diagram are homologous structures that were fossilized, we can say that option 1 is the correct answer to your question.
