One biotic factor that affects consumers in an ocean ecosystem is...
salt content
O number of autotrophs
O temperature variation
O pH of water
One biotic factor that affects consumers in an ocean ecosystem is Salt content.
What are Salt content?The mother and fetus undergo a change throughout the second trimester. Typically, you'll start feeling better and displaying the pregnancy more.
The fetus has completed the development of all of its organs and systems and is about to start expanding in size.
The umbilical cord continues to thicken as it supplies the fetus with nutrients during the second trimester. However, dangerous substances can also transfer from the mother to the fetus through the umbilical cord, so caution should be taken to stay away from known dangers like alcohol and tobacco.
Therefore, One biotic factor that affects consumers in an ocean ecosystem is Salt content.

what do the results suggest about ways that milkweed bug populations are limited in nature?
Answer:
Temperature.
Explanation:
Temperature was the only limiting factor that controls and limits the size of the population of milkweed bug in the nature because these milkweed bug are very sensitive to temperature. Little increase or decrease in temperature can cause adverse effect to the population f milkweed bug in that environment. Milkweed bugs need food, water, space, shelter and a mate in order to survive a well as increase in population of milkweed bug.

Will pigs ever fly?
Support your answer with suitable examples.
Answer:
NO
Explanation:
the pigs will never be able to fly as the birds have:
wings – these enable the force of lift.
lightweight, smooth feathers – this reduces the forces of weight and drag
streamlined body – this helps reduce the force of drag (a shape that lowers the friction drag)
light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight
Meanwhile the pig is obviously heavier, having a stronger force of gravity, and does not have the same type of "lightweight" bones that the birds have.
Answer:yes they might
Explanation:
Birds are able to breed with pigs and pigs might get wings

Which type of bond is the strongest?
A. lonic
O B. Covalent
C. Metallic
D. Hydrogen
Answer:
A
Explanation:
The two strongest bonds are ionic and covalent, but generally, ionic is viewed as the stronger bond because of the ion-ion force that occurs within the bond. It does depend on other factors though.
The rising of bread dough is the result of The rising of bread dough is the result of oxygen being released. carbon dioxide produced by fermentation. biotin production. oxidative phosphorylation.
Answer:
Fermentation
Explanation:
Fermentation is the process whereby carbohydrates are converted to acohol or acid by the activities of some enzymes. During the process of fermentation, carbon dioxide is produced and it is found as tiny pockets of air inside the bread dough. This make it to rise. The alcohol produced evaporates later during the bread making process.

Elige un ser vivo y desarrolla sus características comunes con el resto de los seres vivos (formado por células, nutrición, reproducción, respiración, adaptación)
Answer:
- Célula >> unidad básica y funcional de todos los seres vivos
- Nutrición >> proceso de toma de nutrientes del medio ambiente
- Reproducción >> proceso de replicación con el fin de perpetuar la especie
- Respiración >> proceso de intercambio gaseoso en organismos superiores
- Adaptación >> mecanismo por el cual los organismos se ajustan a su ambiente
Explanation:
Un mamífero (por ejemplo, un perro) es un organismo multicelular compuesto por diferentes tipos de células especializadas las cuales se asocian para formar tejidos, que a su vez se asocian para formar órganos y finalmente sistemas de órganos. El sistema respiratorio está compuesto por las vías aéreas y los pulmones. Durante el proceso de respiración se produce el intercambio gaseoso de oxígeno (O2) y dióxido de carbono (CO2) entre los pulmones y la sangre. El oxígeno obtenido mediante la inspiración pasa de los alvéolos pulmonares a la sangre para llegar a cada célula del cuerpo, mientras que en cada expiración se elimina dióxido de carbono en el sentido inverso. La nutrición es el proceso de toma de nutrientes mediante el cual el organismo obtiene energía y materia de su ambiente. Durante este proceso, el sistema digestivo incorpora alimentos que posteriormente son descompuestos en moléculas simples conocidas como nutrientes las cuales son absorbidas para finalmente pasar a la sangre y así llegar a cada célula del cuerpo. La reproducción consiste en el mecanismo mediante el cual una especie se asegura su continuidad a través del tiempo. Los órganos reproductores masculino y femenino están encargados de producir células sexuales, es decir, gametos masculinos (espermatozoides) y gametos femeninos (óvulos) que se unen durante el proceso de fertilización para dar lugar a un cigoto que se desarrollará hasta formar un organismo adulto. Finalmente, la adaptación se refiere al mecanismo por el cual un organismo se ajusta a su ambiente. A nivel de especie, la adaptación es una consecuencia del proceso evolutivo por el cual aquellos organismos que se ajustan mejor a su ambiente tienen más chances de sobrevivir y reproducirse, teniendo por lo tanto más chances de transmitir sus genes a la siguiente generación.

¿Cuáles de las siguientes características permite el intercambio gaseoso entre el Oxígeno (O2) y Dióxido de carbono (CO2) en los alveolos?
Answer:
Difusión y afinidad de la hemoglobina.
Explicación:
La difusión y afinidad de la hemoglobina son las características que permiten el intercambio gaseoso entre el Oxígeno (O2) y el Dióxido de Carbono (CO2) en los alvéolos. Debido a la difusión, las células de hemoglobina descargan o eliminan el gas de dióxido de carbono que es más alto en la hemoglobina en comparación con los alvéolos, por lo que el dióxido de carbono se mueve de la hemoglobina a los alvéolos mientras que, por otro lado, el oxígeno se mueve dentro de la célula de hemoglobina a través de la difusión y la estructura de la hemoglobina atraer y adherir moléculas de oxígeno consigo mismo.
