The genome contains all of the DNA information needed to build and maintain an organism. In humans, the genome contains more than 3 billion DNA base pairs. Most of this genetic information is located in which of these structures within the cell?
Answer: A Genome is an organism’s complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome, more than 3 billion DNA base pairs, is contained in all cells that have a nucleus.
In humans, a copy of the entire genome, more than 3 billion DNA base pairs, is contained in all cells that have a nucleus.
What do you mean by genome?The complete set of DNA (genetic material) in an organism. In people, almost every cell in the body contains a complete copy of the genome.
This set of instructions is known as our genome and is made up of DNA. Each cell in the body, for example, a skin cell or a liver cell, contains this same set of instructions. The instructions in our genome are made up of DNA.
The primary function of the genome is to store, propagate, and express the genetic information that gives rise to a cell's architectural and functional machinery.

Describe the similarities you observe between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants
Help me please
The primary mode of reproduction that separates flowering plants from non-flowering plants. While non-flowering plants need on dispersion to continue their life cycle, flowering plants depend on pollination for reproduction.
What is flowering plants and non-flowering plants?Seeds that are protected by a flower or fruit are used by flowering plants to reproduce.
Conifers, ferns, and mosses are examples of non-flowering plants. Conifers produce seeds in cones to reproduce. Spores are used in fern and moss reproduction.
The reproductive organs of plants, called flowers, transport both male and female gametes.
These flowers bear fruits once fertilised. Non-flowering plants are ones that reproduce by spores but don't produce flowers.
Plants differ in appearance, but they always share three characteristics: they are multicellular; they can produce their own food; and they are green.
Thus, these are some similarities between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants.

How does high altitude affect breathing? please help
Per my research, it was said that the higher the elevation, the more difficult breathing becomes. The air at higher altitudes is colder, less dense, and contains fewer oxygen molecules, which means that you would need to take more breaths in order to get the same amount of oxygen as you would at lower altitudes.
Explanation:Hope this helped and please correct me if I am wrong. I did my research and I think this is right because of the elevation. Have a good one!

Byron goes rafting on the Colorado River. As he paddles along, he can see the erosion, weathering, and deposition caused by the river. Explain how a river is responsible for causing erosion, weathering, and deposition. Give an example of each.
P.s. no links or you will be reported
Answer:
Erosion by a river is caused by its capacity to curve out rocks and carry soil particles as sediments due to its erosion power. Rivers carve out rocks to form the pebbles you see in a river and also the rapids and cataracts.
A river contributes to the weathering of rocks such as limestone rocks. The water dissolves the calcium carbonate minerals in the limestone rocks making it brittle and easily crumble. Water also causes ferrous rocks to easily crumble due to turning of the iron minerals into rust.
rivers deposit their sediments when their velocity decreases. Deposits by rivers cause features like oxbow lakes and deltas that are observed at the mouth of rivers, where the slope gradient is very low.

If I were a predator bird I would find summer easier to hunt. This is because in summer all the animals are not hiding in their homes or resting.
What do you mean by predators?A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation and parasitoidism.
Predation involves four steps: search, recognition, capture, and handling. The possibility of co-evolution of predator and prey operates at each of these steps. Predators search the environment for acceptable prey.

Answer:
kinetic is the awnser
when an object is gaining forice it kenetic
Answer:
Potential
Explanation:
Potential energy is when you store up energy.
Kinetic, is when you use that stored up energy to move something (or try to).
In this case, the baseball player is storing up energy to through the baseball.
If the sentence was a baseball player threw the baseball, then it would be kinetic.
Because the baseball player is not moving the ball, it's potential energy.
Could the blue jays ever have had thin beaks? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)
1. No blue jays could have been born with a thin-beak trait because none of the adult blue jays had that trait to pass down.
2. No blue jays could have been born with a thin-beak trait in the past, but some with that trait could be born in the future if the environment changes to have pine cones with seeds.
3. A blue jay could have been born with a mutation in its genes for the thin-beak trait and lived for a little while, but it would have been more likely to die before it had offspring.
4. A blue jay could have been born with a mutation in its genes for the thin-beak trait, but having a mutation in its genes would have caused it to die when it was born.
Answer:
i believe the answer is 2)
Explanation:
because birds that eat seeds need to have thinner beaks in order to get to the seed. seeing as how their beaks are currently too large for that, they wouldn't be able to reach the seeds- they would have to adapt to the new environment **if that were to happen**
good luck :)

The image shows an example of an external environment affecting her fish's growth. Other conditions that could affect animal growth include internal environment.
What is environment?An organism's or an ecological community's environment is the collection of physical, chemical, and biological variables that affect it and ultimately decide its form and survival.
Everything in our environment affects us. Whether they are living or not is up to you. It consists of natural forces such as chemical and physical ones.
Environments are where living things exist. They are continually interacting with it and modifying their behavior to fit the circumstances.
Clean air and water, rich land for growing food, as well as energy and material inputs for production, are all provided by good natural surroundings.
The picture demonstrates how an outside environment can effect a fish's growth. Internal environment is another factor that might influence an animal's growth.
Thus, this can be the complete scenario for the gold fish.

Answer:
I think it's C. it's sexual reproduction because the sperm and egg is comming from two different salamanders, not the same one. Since the egg and sperm are from different salamanders then there will be genetic variation in the offspring because the DNA from two different salamanders are present in the offspring.
