Answer:
human blood is red because of the protein hemoglobin, which contains a red-colored compound called heme that's crucial for carrying oxygen through your bloodstream. Heme contains an iron atom which binds to oxygen; it's this molecule that transports oxygen from your lungs to other parts of the body.

carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. this special ability allows carbon to do what?
Answer:
To form a wide range of compounds with other elements
Explanation:
The ability of carbon to gain four more electrons allows this chemical specie to form a wide range of compounds.
When carbon gains four electrons, it becomes isoelectronic with neon and then becomes a stable compound or molecule as it combines with other atoms.
This leads to the proliferation of carbon compounds that we find in nature. Carbon can easily for covalent compounds with other compounds also.
How does oxygen enter the cells of the tube worm
Answer:
Flatworms are small, literally flat worms, which 'breathe' through diffusion across the outer membrane (Figure 2). The flat shape of these organisms increases the surface area for diffusion, ensuring that each cell within the body is close to the outer membrane surface and has access to oxygen.

What happens to carbon in plants when the plants die?
1. The carbon is not released; it is lost.
2. The carbon is released into the air.
3. The carbon will be released into the soil for use by the next generation.
4. The carbon is released into the soil, but it is not used again.
Answer:
The carbon dioxide is released into the air after the plant dies
Explanation:
Suppose you mate a black rooster with a white hen. The feathers of all the offspring are "gray," a color that is intermediate between black and white. Explain the inheritance pattern in these chickens.
Answer:
The correct answer is - incomplete dominance
Explanation:
An incomplete inheritance or incomplete dominance is an inheritance pattern when the dominant allele of the particular trait is not able to completely mask the effect of the recessive allele and express the mixed or intermediate effect of both the alleles.
Since the gray color is the expression of the mix or intermediate character of both dominant and recessive alleles between black and white, incomplete dominance is the simplest way to explain the inheritance of this character.

Keratinocytes make keratin, a type of protein that's a basic component of hair, skin, and nails. Keratin in the skin's outer layer helps create a protective barrier.
Population density is calculated by
Answer:
C.
Explanation:
To calculate the population density, you will divide the population by the size of the area. Thus, Population Density = Number of People/Land Area. The unit of land area should be square miles or square kilometers. You can use square feet or meters if you are finding the density of a smallish space.

answer 2
Explanation:
its not a sign because thats just something she is telling you, everything else is something you can see
Answer:
she is bleeding
Explanation:
an allergic reaction wouldn't hurt it would itch, but it depends on where the reaction has formed. but it says that she was scratching the area of concern making it bleed so yes that would hurt. Benadryl would be a good idea to get the reaction to calm down but you need to stop the girl from scratching the area otherwise it will get worse i dont know if im right, im very sorry if its wrong

Is a cell membrane more like a brick wall or a chain-link fence? Why?
Answer:chain-link fence
Explanation:a cell membrane is partial permeable which means that it lets some substances through but not other.
Answer:
Chain-link fence
Explanation:
Cell membranes are barriers that decide which molecules enter and exit the cell, and how much of them come in. So things are able to pass through them.
If it were a brick wall, it would not let anything pass through.
So it is more like a chain-link fence, but with more control over what passes through it.
What is the difference between the euphotic zone and the bathyal zone of the ocean
Answer:
Euphotic zone is the layer closer to the surface that receives enough light for photosynthesis to occur. Beneath lies the disphotic zone, which is illuminated but so poorly that rates of respiration exceed those of photosynthesis.
Bathyal zone is the part of the pelagic zone that extends from a depth of 1000 to 4000 metres below the ocean surface. It lies between the mesopelagic above, and the abyssopelagic below.It is ala known as midnight zone.

What is the primary function of the light dependent reaction of photosynthesis
Answer:
The overall purpose of the light-dependent reactions is to convert light energy into chemical energy.
Hope this helps :)
Explanation:
The light dependent reaction of photosynthesis is the stage that has the function of converting light energy into stable chemical energy.
Photosynthesis as a chemical process occurs in two different stages: the light stage and the dark stage, so called because only the first is directly involved in the presence of sunlight.
During this phase, bioluminal reactions take place inside the plant, that is, the plant captures solar energy through chlorophyll and uses it to produce ATP and NADPH.Therefore, we can conclude that the light dependent reaction of photosynthesis is this biochemical stage of harnessing sunlight to obtain organic materials.

Train a pull into the sation every 6 hours . The train B pulls into the sation every 3 hours . They both pulled thr sation at 3pm. When is the next time they with both pull into the sation at the same time?
Answer:
9 pm
Explanation:
A pulls into the station every 6 hours while B pulls into the station every 3 hours. Hence, for every time A pulls up, B must have pulled up twice.
They both pulled into the station at 3 pm. At 6 pm (3 pm + 3 hours), B would pull into the station while A would still be on the road. At 9 pm (3 pm + 6 hours), B will pull in once more while A will just be pulling up the first time since 3 pm.
Hence, the next time both trains will pull into the station at the same time would be 9 pm.

Describe how traits are inherited through traits sexual Reproductions
WILL MARK AND 5 STARS
Answer: sexual reproduction is the union of male and female gametes to form a fertilized egg, or zygote. The resulting offspring inherit one half of their traits from each parent. The process where haploid sex cells are created from diploid parents is called meiosis, and it occurs only in the reproductive organs.
Explanation:
i have advanced so this is what i got right
Answer: In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.
