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

Answers

Answer 1

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 is succession?

It is the gradual change to the community of plants and animals in an ecosystem until a stable community is reached.

Succession can be primary or secondary. Primary succession happens on newly colonized bare grounds of stones while secondary succession happens in an existing community after a period of disturbance such as wildfire.

A forest ravaged by fire will have all the animals dead or away for safety reasons. These animals may not come back until regrowth has reached a certain level.

However, propagules of grasses are often fire-resistant and even get stimulated by fire in most cases. Thus, the first type of organism to be found living in the burned area could be grasses.

Answer:

50%, and 0%

Explanation:

Make a chart, and fill it in
a)
_ |E   |   e
e |Ee | ee
e |Ee | ee
2/4 have Ee, and 2/4 have ee, ee is the attached, so the chance is 2/4, or 50%
b)
hom*zygous means that both letters are the same, so EE, or ee
the mother is EE, while the father is ee
make a table:
_ |E   |   E
e |Ee | Ee
e |Ee | Ee
As you can see, it's all Ee, so the only possibility is for the child to have detached earlobes, and no attached earlobes are produced (in theory, at least)

How does the haploid form of ulva switch to its diploid form?.

Answers

Gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote.

The haploid form of Ulva switches to the diploid form when gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote. Therefore, option D is correct.

What are gametophytes?

The sexual stage in the alternation of plant generations and some algae is called a gametophyte. This stage results in gametes that go through generational alternation. It produces the zygote from which sporophytes develop and is a haploid phase.

The gametophyte stage of life is the predominant one in bryophytes. The male and female gametes are produced by the gametophyte's antheridia and archegonia, respectively. Gametangia are all of these structures put together.

Thus, the haploid form of Ulva switches to the diploid form when gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote. Therefore, option D is correct.

Mary loved having her goldfish tank in her office. She said watching the fish swim around was calming to her on stressful days. Mary thought that if 2 goldfish in her tank could make her less stressed then certainly 8 goldfish would be even better. After three days of having 8 goldfish in her tank, she noticed 5 of the fish began to sink to the bottom of the tank becoming less active than the remaining 3. A few days later the 5 sick fish died and the 3 remaining fish thrived. Use the data to help you choose three reasons the carrying capacity of the fish tank wasn’t able to accommodate all 8 goldfish.

How could harm to one resource among the commons listed in part b cause harm in another part of the environment?

Answers

Answer:

Take a picture of what the problem is, because your question isn't clear

Explanation:

Not using complete sentences

For example, overfishing can harm fish populations, leading to imbalances in the food chain and harm to other species.

What are commons?

The commons, as a concept, refers to shared resources that are available to all members of a community or society. These resources can include things like air, water, land, and wildlife. When harm is caused to one of these resources, it can have a cascading effect on other parts of the environment.

For example, if pollution from a factory contaminates a river, it can harm the fish and other aquatic life that live in the river. This, in turn, can impact the local ecosystem and reduce the biodiversity of the area. The contaminated water may also be used for agriculture, leading to contaminated crops and potentially harming human health.

Similarly, deforestation can lead to soil erosion, which can cause sedimentation in rivers and harm aquatic life. It can also contribute to climate change by reducing the amount of carbon that is absorbed by trees and released back into the atmosphere.

In summary, harm to one resource among the commons can have far-reaching effects on other parts of the environment, highlighting the importance of managing these resources sustainably.
