if we have red veins and red blood how do we have blue veins in our bodies FIRST ONE TO ANSWER AND EXPLAIN GETS BRAINILEST PLEASE HELP
Answer:
The colors we see are the result of which wavelengths of light are reflected back to our eyes. Veins appear blue because blue light is reflected back to our eyes.
Blue light does not penetrate human tissue as deeply as red light does. As a result, veins that are close to the surface of the skin will be more likely to reflect blue light back to the eye.”
In short, our veins appear blue because of a trick that light plays on our eyes and how the light interacts with our body and skin. All color works this way as light is a combination of all colors and when it reflects off of certain materials, it absorbs some colors and bounces back others to our eyes.

What does dna have that determines all my traits
Answer:
These sections of DNA that contain information that determine your physical features are called genes. Since you have two pairs of chromosomes, you also have two pairs of genes, one from your father and one from your mother. These pairs of genes then determine certain physical features or traits.

The palisade layer contains the most chloroplasts as it's far close to the pinnacle of the leaf. The chloroplasts comprise the pigment chlorophyll. The palisade cells are organized upright.
When does a zygote become an embryo?
once the embryo forms a heart, lungs, and brain
a few minutes after the male and female gamete fuse
once the zygote enters a safe environment either inside or outside of their mother
once the zygote starts dividing by mitosis and cell differentiation occurs
Answer:
Explanation:
The transformation of a zygote into an embryo adheres both to nature and to nurture: not only genetics but also environment determines the outcome. This idea has assumed many forms. A territory in the early sea urchin blastula contains clones of founder cells, and each clone contributes exclusively to one territory (Cameron & Davidson, 1991). Both the lineage of a founder cell, i.e. its nature, and the position of a founder cell, which determines how it is nurtured, contribute to its fate. Fertilisation, the topic of the first Forum, fixes the genes; interblastomere communication, the topic here, regulates gene expression. Blastomeres communicate like any other cell – via ligand-receptor interactions and through gap junctions. Saxe and DeHaan review these mechanisms. The definition of ligands and receptors becomes broadened in this context, and cell adhesions as well as gap junctions enter into the story. In spite of these entanglements, it appears that nature uses the same sorts of mechanisms to get cells to specialise that she uses to keep them talking. Thus, neurons and glial cells signal to one another via glutamate receptors and gap junctions (Nedergaard, 1994). Likewise, we expect neurotransmitters (and neurotransmitter transporters) to help signal differentiation. The biophysicist may ask whether electrical properties also play a role, but that we reserve for another Forum. If gap junctions figure in development as fusion pores that pass small molecules and electrical signals between blastomeres, another parallel suggests itself. Brian Dale asked in the first Forum: How does a spermatozoon activate an oocyte? This question, which concerns gamete communication, has produced two schools of thought and remains controversial (Shilling et al., 1994). Do sperm activate oocytes via contact-mediated mechanisms or through fusionmediated mechanisms? Or do both mechanisms occur, as they appear to in development?

Which animal trait was Darwin's theory of natural selection based on? (1 point)
O swimming ability of Galápagos iguanas
O beak morphology of Galápagos finches
O predatory behavior of foxes
o coloration of peppered moths
Answer:
beak morphology of Galápagos finches
Answer:
Beak Morphology.
Explanation:
His theory was based off of the finches from different areas and their ability to pick up food. The beak shape was based off of the diet of the bird. For example, if a finch had a diet consisting of seeds, it had a dense, powerful beak that was able to crush the seed.

Scientists have observed that in the Antarctic ecosystem Adélie and Chinstrap penguin populations have decreased in the past 40 years by about half. However, Gentoo penguin populations have remained steady and are possibly increasing. Increasing ocean temperatures in the Antarctic is resulting in less sea ice and less krill because krill depend on sea ice.
Which statement, if true, BEST explains why Gentoo penguins have a survival advantage in the changing Antarctic environment?
A.
Adult Gentoo penguins average about 0.5 kilograms more in weight than adult Adélie and Chinstrap penguins.
B.
Leopard seals prey heavily upon juvenile penguins.
C.
Gentoo penguins eat more types of prey than either Adélie or Chinstrap penguins.
D.
Penguins spend a large amount of their energy on keeping warm during harsh winters with very low temperatures.
Answer:
C.
Gentoo penguins eat more types of prey than either Adélie or Chinstrap penguins.
Explanation: It makes the most sense over the other ones.
What accounts for the climate change that is seen among the galapagos islands?
a. distance from the equator
b. ocean currents
c. difference in elevation
Ocean currents is responsible for the climate change at the galapagos islands.
Impact of ocean currents on the climate of galapagos islandsWeather in the Galapagos is different from other higher latitudes because of its geographical location. The ocean currents bring a unique seasons and climatic conditions. The climate is warm, rainy season and the cool.

Elisabeth is an oceanographer. On which of the following research expeditions would she travel from the photic zone to the aphotic zone?
A.) A snorkel trip from the intertidal zone to 55 feet off the beach
B.) A scuba trip from the surface down 100 feet
C.) A submersible traveling from the ocean surface to the abyss
D.) A research vessel from the beach to the open ocean
A research expedition traveling from the photic zone to the aphotic zone, is a submersible traveling from the surface of the ocean to the abyss.
What is aphotic zone and photic zone?Depending on the lighting, the waters are divided into:
PHOTIC ZONE → up to 200 m deep. DYSPHOTIC ZONE → between 200 m and 400 m deep. APHOTOTIC ZONE → below 400 m depth.With this information, we can conclude that a research expedition traveling from the photic zone to the aphotic zone, is a submersible traveling from the surface of the ocean to the abyss.

What type of fuel does each energy system produce?.
Answer:
carbon?
Explanation:
Energy systems produce ATP, during every process cellular respiration is the major process of the system.
How ATP as fuel produce by each energy system?During cellular respiration, all the metabolic intermediates finally produce ATP, and in glycolysis, the Kreb cycle produces reducing products which finally oxidize in the electron transport chain.
The electron transport chain produces fuel as ATP, it is an enzymatic chain reaction that produces an electromotive force that is responsible for the production of ATP.
ATP is a major fuel for every cellular process which acts as an energy form that is extracted from metabolic intermediates.
Therefore ATP is a major fuel produced by the system.
