What delivers oxygen around your body to different organs and tissues
Answer:
The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. The arteries carry blood away from the heart; the veins carry it back to the heart.

Si tu masa corporal fuera 10 kg, ¿qué peso tendrías aquí en la tierra al
nivel del mar?
Answer: 98.1 N
Explanation:
En física, la masa es una magnitud y una propiedad que se mide en unidades, como kilogramos. Por otro lado, el peso es una magnitud vectorial o fuerza que se mide en netown (N). El cuerpo experimenta una atracción hacia la tierra, llamada gravedad, la cual es un fenómenos en donde dos objetos o cuerpos son atraídos entre sí. En este caso, la masa del cuerpo de 10 kg es muy inferior a la masa de la Tierra. Por lo que la atracción del cuerpo hacia la tierra es despreciable, y solo vamos a tomar en cuenta la atracción de la Tierra hacia el cuerpo.
La fuerza de gravedad a nivel del mar es de 9,81 metros/segundos^2. Reemplazando los datos en la ecuación de fuerza, la cual es:
Fuerza = masa x aceleración
obtenemos que:
Fuerza= 10 kg x 9,81 m/s^2 = 98.1 N
Por lo que el peso a nivel del mar es de 98.1 N.

Explanation:
1. What gene involved in skin pigment varies a great deal across populations?
2. Why doesn’t skin cancer explain this selection?
3. What does strong sunlight do to folate?
ALOT OF POINTS!!!!!
Answer:
Explanation:12werffdew
Answer:
1.A number of genes have been positively associated with the skin pigmentation difference between European and non-European populations. Mutations in SLC24A5 and SLC45A2 are believed to account for the bulk of this variation and show very strong signs of selection.
2.Cancer can circumvent negative selective pressures due to its ability to accumulate mutations that cause genetic diversity in tumor cells as the cells proliferate. Cancer seems to have evolved a propensity for, or at the very least, a selection for fitness.
3.Folate levels decrease depending on sun exposure, study says. 05 Feb 2019 --- Folate levels decrease during the months when solar radiation is higher and ultraviolet radiation proportionately affects folate levels in the blood.

Why do we not see the colors of the other pigments, such as yellow?
Answer:
there is so much chlorophyll in the leaves we simply cannot see the other pigments. But as the daylight shortens, the tree does not make as much chlorophyll. As the chlorophyll starts to fade away, we are able to see the other colors (pigments) in the leaf, mostly yellow ones.
Explanation:
Answer:
Subtractive color mixing occurs when light is reflected off a surface or is filtered through a translucent object. For example, a red pigment or filter only appears red because it absorbs (subtracts) all of the light that is not red and only reflects or allows the red light. if you mix blue with red light, you get magenta light. When you mix (add) all the colors of light together, you get white light. This is why it is referred to as additive color. With subtractive color, you see color because some wavelengths are being reflected and others are being absorbed ( subtracted ).

Explanation:
Why is the first hill of a roller coaster always the tallest? Explain.
Answer:
The first hill of a roller coaster is always the highest point of the roller coaster because friction and drag immediately begin robbing the car of energy. At the top of the first hill, a car's energy is almost entirely gravitational potential energy (because its velocity is zero or almost zero
Explanation:
Because friction and drag start depriving the car of energy right away, the first hill of a roller coaster is always the steepest part of the ride.
What is friction?The resistance to motion created when two objects rub against one another is called friction. Friction occurs whenever two items come into contact with one another. Friction acts in the opposite direction from the motion and works against it. The two surfaces' respective materials have an impact on how much friction exists.
Static friction, sliding friction, rolling friction, and fluid friction are the four main categories of friction.
Friction and drag start depriving the car of energy right away. Therefore, the first hill of a roller coaster is always the tallest.

What ratio of plants in the offspring would you predict from a Yy x Yy cross?
Answer:
The correct answer is -
The genotype of offspring - 1:2:1 (YY:Yy:yy)
The phenotype of offspring - 3:1 (dominant trait: recessive trait)
Explanation:
In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y
then the cross of Yy and Yy would be -
Y y
Y YY Yy
y Yy yy
Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.

Answer:
(B) Similarities among Hox genes suggest that they all arose from a single ancestral gene that duplicated many times.
Explanation:
Hox genes are arranged in clusters and their order on the chromosome is the same as the order in which they are expressed along the body during development.

What do you mean by biodiversity?The variety and variety of life on Earth is called biodiversity or biological diversity. Biodiversity is a proportion of variety at the hereditary, species, and biological system level.
The diversity of the various kinds of organisms—the plants, animals, insects, and microorganisms that inhabit our planet—that can be found in the natural world around us is called biodiversity.
The majority of people recognize biodiversity by species, which is a group of distinct, interbreeding living organisms. Blue whales, white-tailed deer, white pine trees, sunflowers, and even microscopic bacteria.
