What would happen if we continued to overharvest swordfish?
Answers
Answer:
Overharvesting fish depletes some species to very low numbers and drives others to extinction. In practical terms, it reduces valuable living resources to such low levels that their exploitation is no longer sustainable.
Overharvesting swordfish could cause their extinction and mess up the food chain, harming (starving) their predators.
Answer:
They'll go extinct

The table below lists the characteristics of genetic material isolated from a bacterium, a plant cell, a virus, and ribosome. Which source is the virus?
A.) #2
B.) #1
C.) #4
D.) #3
Answers
Answer:
Option D, Sample 3 is the sample extracted from a virus
Explanation:
Uracil is less expensive as compared to thymine and hence it is found in RNA. Also, RNA virus has RNA or single stranded DNA. The RNA of virus has Uracil instead of thymine in its genetic material
Hence, option D is the correct answer.
Option A is incorrect because sample 2 has two strands while virus has only 1 strand
Option B is incorrect because sample 1 has a circular DNA while virus as linear genetic material
Option C is incorrect because sample 4 has 2 stands while virus has only 1 strand and it also has thymine instead of uracil
Based on the data provided, the source of the virus is #3.
What is the nature of the genetic material of a virus?The genetic material present in a virus can either be DNA or RNA.
The genetic material is single stranded.
For RNA viruses, uracil is found in place of thymine.
From the data provided, there is only one single-stranded genetic material and it has uracil in place of thymine.
Therefore, based on the data provided, the source of the virus is #3.

Which statement is incorrect about the adult human heart?
Question 28 options:
Blood in the right ventricle is deoxygenated.
Blood in the left ventricle is deoxygenated.
Blood in the pulmonary artery is deoxygenated.
Blood in the pulmonary vein is oxygenated.
Answer not listed
Answers
Answer:
B. Blood in the left ventricle is deoxygenated.
Explanation:
Human heart consists of four chambers namely: right atrium, right ventricle, left atrium and left ventricle. These chambers work hand in hand to perform the function of circulating blood throughout the body.
- The RIGHT ATRIUM receives deoxygenated blood from the heart and passes it to the RIGHT VENTRICLE, which pumps it to the lungs in order to be oxygenated.
- The LEFT ATRIUM receives oxygenated blood from the lungs and passes it to the LEFT VENTRICLE, which pumps it into the body.
- Also, the pulmonary artery carries deoxygenated blood into the lungs for oxygenation while the pulmonary veins carry oxygenated blood from the lungs
Based on the above explanation of the right & left atria and the right & left ventricles, it is FALSE that the blood in the left ventricle is deoxygenated. It is rather oxygenated.
In an ecosystem, what are some living and nonliving things that affect the ecosystem?
Answers
Answer:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem.
Explanation:
Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die. Some examples of living things are organisms such as plants, animals, fungi, and bacteria.

If I had a superpower, it would be that I was fluent in every language. I would use this superpower to do things such as travel, and better understand current events happening around the world.
This superpower would help me, because I'd have the ability to speak to any person, and read any book. I would be able to travel anywhere I want without having to worry about a language barrier. I would also be able to have a better understanding of current and pasts events that have happened in other countries, as I would be able to understand resources that are in other languages.
This superpower would also be beneficial to the public, because I could easily translate between two people. Having a person who is fluent in every language could help improve communication in personal, professional, and government relationships. It could allow for people from many different countries come together and share ideas easily.
I think that having the superpower of being able to speak, read, and write every language would be beneficial to both myself, and the public. It would help me personally, as I wish to travel to many places, and it would help the public because the language barrier negatively impacts people's ability to communicate with those who speak another language.

Si usted sitúa un grupo de plantas verdes (que realizan fotosíntesis) dentro de un ambiente rico en CO2 (dióxido de carbono) con el carbono marcado radiactivamente, es decir, puedo seguir el rastro del carbono. ¿En qué moléculas espera encontrar la marca al interior del cuerpo vegetal?
Answers
Answer: Esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.
Explanation:
La fotosíntesis es un proceso utilizado por las plantas y otros organismos fotoautótrofos para convertir la energía de la luz en energía química que, a través de la respiración celular, puede utilizarse para llevar a cabo distintas actividades metabólicas. Esta energía química se almacena en moléculas de carbohidratos, como los azúcares, que se sintetizan a partir de dióxido de carbono y agua. También se libera oxígeno como producto de desecho.
La energía de la luz es absorbida por unas proteínas llamadas centros de reacción que contienen pigmentos verdes de clorofila. En las plantas, estas proteínas se encuentran en el interior de unos orgánulos denominados cloroplastos, que son los más abundantes en las células de las hojas, mientras que en las bacterias están incrustadas en la membrana plasmática. En estas reacciones dependientes de la luz, se utiliza una parte de la energía para despojar de electrones a sustancias adecuadas, como el agua, produciendo gas oxígeno. El hidrógeno liberado por la ruptura del agua se utiliza en la creación de otros dos compuestos que sirven como almacenamiento de energía a corto plazo, permitiendo su transferencia para impulsar otras reacciones: estos compuestos son el nicotinamida adenina dinucleótido fosfato reducido (NADPH) y el adenosín trifosfato (ATP), la "moneda energética" de las células.
El almacenamiento de energía a largo plazo en forma de azúcares se produce mediante una secuencia posterior de reacciones independientes de la luz denominada ciclo de Calvin. En el ciclo de Calvin, el dióxido de carbono atmosférico se incorpora a compuestos de carbono orgánico ya existentes, como la ribulosa bifosfato (RuBP). Utilizando el ATP y el NADPH producidos por las reacciones dependientes de la luz, los compuestos resultantes se reducen y se eliminan para formar más carbohidratos, como la glucosa.
Entonces, si el carbono en la molécula de dióxido de carbono (CO2) se encuentra marcada radiactivamente, esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.

The is concluded that spider silk flexibility varies because their offspring inherited different combinations of gene versions from their parents, demonstrating that spider silk quality is dependent on the gene present in it.
What is the significance of the spider's silk?The quality of the spider silk is genetic, and due to this, some of the spiders do produce high-quality silk while others produce average or poor-quality silk, but the silk has many applications in various fields, such as biomedical fields such as in tissue engineering, drug delivery, and wound healing, due to its biocompatible, non-toxic properties.
