Answer:
veins and arteries
Explanation:
veins carry deoxygenated blood from the cells in the body to the heart and arteries vice versa
The circulatory system consists of veins and arteries which circulate blood from the heart to the lungs to get oxygen. The arteries carry oxygenated blood to the rest of the body from the heart. The veins bring oxygen-depleted blood back to the heart, where it is circulated again.
The blood gets oxygenated in the lungs. The arteries which carry oxygenated blood from the lungs to the body parts is known as the pulmonary artery. It enters the heart through the left atrium. The left ventricle then pumps the blood through the aortic valve into the aorta.

How has modern humans
ecological footprint caused a Tragedy of the Commons?
Answer and Explanation:
The ecological footprint is an indicator of sustainability at an international level that integrates all the human impacts over the environment, considering the necessary resources and the generated residues to maintain the modern consumption model. It refers to the productive ecological surface needed to produce resources to consume by one person and to absorb the residues that are produced.
By constant contamination and indiscriminately use of natural resources the impact generated by human in the earth is unmeasurable.
The tragedy of the commons refers to how some people, acting by their own needs or interests, may exceed the use of natural resources, affecting their population and, therefore, other users. These individuals over explode resources thinking only in the present, but not in the future.
The ecological footprint as an indicator makes visible the unsustainable lifestyle of human beings, especially those of the first world. If this lifestyle would project to the rest of the world equally, natural resources would completely disappear. More developed countries are over contaminating and over exploding natural resources, affecting other countries of the third world, and even themselves.
Marine biologist, Igor Vladimir, is conducting research on the 25-40 cm in diameter, Aurelia aurita, commonly known as the moon jellyfish. He is trying to determine how much water is needed to propel the translucent jelly, that is capable of only limited motion, and drifts with the current, even when swimming. Which of the images, A or B, most likely represents a measurement this scientist made? Justify your answer.
Answer:
Image A
Explanation:
The most likely image that represents the measurement of the scientist would be image A.
Image A indicates the shape that water would form in a tube. Due to the adhesive force between the molecules of water and the wall of the tube, the surface of water usually forms a concave shape in a tube. Hence, the lower meniscus of the water is usually read in a tube which is what image A represents.

What are viruses considered to be non-living?
Answer:
Viruses are often considered non-living because outside of a living cell, they do not exhibit the characteristics of living organisms: they are basically like crystals. But within a living organism, they become activated and are able to carry out life's activities like replication (a form of reproduction).
Answer:
Viruses are not made up out of cells they cant keep them selves in a stable state they dont grow and they dont make there own energy. So they are considered non-living.
Explanation:
Cells are living things in the body a virus is what the cells are trying to defeat and because there are no cells in viruses the cells in our body is what fights off the virus cause they are alive and processing in our body.

which nitrogenus based is found in Rna but is not found in Dna
Answer:
Uracil
Explanation:
Answer:
Uracil (U)
Explanation:
The nitrogenous bases in DNA are:
- Adenine
- Thymine
- Guanine
- Cytosine
The nitrogenous bases in RNA are:
- Adenine
- Thymine
- Guanine
- Uracil
When we compare the two lists, we see that both DNA and RNA have Adenine, Thymine, and Guanine. However, we can also notice that only RNA has Uracil. Plus, only DNA contains Cytosine.
Therefore, the nitrogenous base found in RNA, but not DNA is uracil.

Son músculos antagonistas (unos realizan flexión y otros extensión) los siguientes: * 5 puntos Trapecio- deltoides Bíceps- tríceps Serratos- rectos Frontal- orbicular
Answer:
Bíceps- tríceps
Explanation:
Los músculos trabajan para generar movimiento mediante la contracción de células musculares. El bíceps y el tríceps son músculos antagonistas presentes en el brazo. Cuando el brazo se acorta, el bíceps funciona como agonista (es decir, se contrae) y hace que los tendones que tiran de los huesos del antebrazo puedan doblarlo. Durante este movimento, el triceps funciona como antagonista, encontrándose en estado de relajamiento. Por otra parte, durante el estiramiento del brazo, las funciones de estos músculos se invierten, con lo cual el tríceps (agonista) se contrae y el bíceps (antagonista) se relaja.

6. Los seres humanos producen desechos celulares que salen del cuerpo gracias a diferentes procesos de los cuales están a cargo varios sistemas, selecciona uno que NO haga parte de este proceso: A. Sistema urinario B. Sistema respiratorio. C. Piel. D. Sistema reproductor.
Answer:
D. Sistema reproductor.
Explanation:
La excreción es el proceso de eliminar los desechos y el exceso de agua del cuerpo. Estos desechos pueden ser dañinos y pueden causar daños.
Los órganos responsables de la excreción son el riñón, los pulmones, la piel, el hígado y el intestino grueso.
La piel elimina el sudor, el exceso de agua y las sales a través de las glándulas sudoríparas.
El sistema urinario está formado por riñón, uréteres, vejiga y uretra. El riñón elimina el exceso de agua y sal al producir orina que luego se transporta con la ayuda de los uréteres, la vejiga y la uretra.
En el sistema respiratorio, los pulmones excretan sustancias gaseosas, como dióxido de carbono y agua.

10) Check three activities/characteristics that would help in becoming a successful biologist.
video game expertise
I love of novels
U political motivation
observation
curiosity
epicureanism
o determination
Answer:
Observation
Curiosity
Determination
Explanation:
A biologist is a scientist that specializes in the study of biology or life generally. However, to become a successful biologist as stated in the question, the three mentioned characteristics needed are:
1. Observation- being an observer is key to becoming any scientist, including a biologist. Observation is the foundation of a scientific method i.e. it begins the process. Hence, a biologist must have good observation skills in order to thrive.
2. Curiosity- Curiosity refers to the ability to want to know what's going on. It's being inquisitive in order to learn new things. Asking questions is equally an important part of a scientific method as it determines the experiment. The question asked is what creates the experiment. Hence, being curious is a good quality for an intending biologist.
3. Determination: Being determined is not a quality only a biologist should possess. Determination is a must for any individual in any field. It is the ability to carry on irrespective of setbacks, which are inevitable.
