Vectorborne transmission of an infectious organism occurs via <u>animals or insects. </u>

Vectors are living organisms that can transfer an infectious disease from infected animals to humans. These species are known as arthropods. It includes mosquitoes, ticks, triatomine bugs, sandflies, etc.

There are two types of vectors; Biological and mechanical.

Biological vectors such as mosquitos transmit the disease by biting the host body. Mechanical vectors on the other hand cause infectious disease just by physical contact.

Arthropod vectors are cold-blooded. The diseases that are transmitted by them are known as vector-borne diseases. Malaria and Dengue are examples of vector-borne diseases.

Que tipo de aislamiento reproductivo exhibe la mula?
bulgar [2K]

Answer:

<em>Aislamiento postreproductivo: Esterilidad del híbrido</em>

Explanation:

El concepto biológico de <u>especie</u>, en su definición, destaca que los ejemplares de una especie no pueden entrecruzarse con ejemplares de otra especie distinta, o bien, en caso de hacerlo, no hay éxito reproductivo.

Existen distintos mecanismos de aislamiento reproductivo, que son barreras que inhiben o interrumpen el flujo génico entre especies distintas. Se trata de caracteres biológicos propios de cada especie que previenen la reproducción con otras especies.

Estos mecanismos de aislamiento reproductivo pueden ser precigóticos o postcigóticos.  

  1. Pre-copulatorios o pre-cigóticos:
  • Ecológico o por aislamiento de hábitat;
  • Estacional o temporal;
  • Sexual o etológico;
  • Mecánico;
  • Por incompatibilidad de gametas.  

   2. Post-copulatorios o cigóticos:

  • Inviabilidad del híbrido;
  • Esterilidad del híbrido;
  • Híbrido con viabilidad o fertilidad disminuido;
  • Interacciones citoplasmáticas.

La mula es producto de la cruza entre dos especies distintas: una yegua (<em>Equus ferus caballus</em>) y un burro (<em>Equus africanus asinus</em>). Es un ejemplo de la accion de mecanismo poscigótico, en el cual se forma un híbrido viable esteril. Este ejemplar puede nacer crecer y sobrevivir, pero que no pueden producir gametas funcionales, por lo cual no pueden reproducirse.

Why is the mitochondria arranged around the filament near the tail of the sperm.
klasskru [66]
Answer: A small middle portion of the sperm contains the mitochondria. The tail of the sperm, sometimes called the flagellum, is a slender, hairlike bundle of filaments that connects to the head and middle portion. The tail gives the sperm cell movement. It whips and undulates so that the cell can travel to the egg.

Glucose is present in blood plasma at a concentration of approximately 80 mg/dL. A typical 70 kg human has approximately 5 L blo
tester [92]

Answer: 48.93 mL of sprite

Volume of blood in 7 Kg human = 5 L

Percentage of plasma in blood = 55%

Volume of plasma in 5 L blood =  (1 L = 10 dL)

Concentration of glucose in plasma = 80 mg/dL

Amount of glucose present in 27.5 dL : 80 mg /dL × 27.5 dL= 2200 mg

Let the volume of sprite with 2200 mg glucose be x

Concentration of glucose in sprite = 44.96 mg/mL

Is the only thing that is not living
3241004551 [841]

Answer:

The main difference between living and non-living things is that a living organism is or was once alive, whereas a non-living thing has never been alive. Non-living is not the same as being dead because non-living things were never alive and therefore cannot die.
