4 Spheres Observation (Bio, Geo, Atmo, Hydro) : What did you see that represents each? How did they interact with each other? and pls be specific in ur answer, and pls no links!
Answer:
The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.
For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.
Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.
Humans have a huge impact on all spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere. And overfishing and habitat destruction can reduce the diversity of living things in the biosphere.
However, people everywhere are working to change things. Recycling efforts are increasing all over the world, and companies are finding new ways to reduce fossil fuels. In the US alone, people are recycling six times more than a generation ago.

Following the fusion of an egg cell and sperm cell, the resulting diploid cell divides by mitosis to create two new daughter cells. Each daughter cell contains pairs of chromosomes, with one set inherited from each parent.
Which of the following best describes the pairs of chromosomes that are present in each newly formed daughter cell?
Choose 1 answer:
A) The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes.
B) The pairs are non-homologous chromosomes that contain different sets of genes.
C) The pairs are homologous chromosomes that have identical copies of every gene.
Answer: A
i have no idea why
The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes. The correct option is A.
What are homologous chromosomes?Among a pair of chromosomes with the very same gene sequence, loci, chromosomal size, and centromere location is referred to as a homologous chromosome.
One paternal and one maternal chromosome make up a homologous pair. In humans, the nucleus of a somatic cell contains 46 chromosomes.
Homologous chromosomes differ from sister chromatids because they are not identical and do not emanates from the same organism.
Sister chromatids are identical, side-by-side duplicates of each other that form as a result of DNA replication.
Homologous chromosomes do not pair together during mitosis. Homologous chromosomes line up end-to-end in mitosis so that when the cells divide, each daughter cell receives a sister chromatid from both members of the homologous pair.
Thus, the correct option is A.

In the diagram of the human digestive system, what organ is labelled 5?
Answer:
The large intestine
Explanation:
The large intestine is a long, tube-like organ connected to both the small intestine and the anus. In an anatomy drawing, it looks almost as if it is wrapped around the small intestine.
As we can see in the drawing, the organ labelled with 5 is wrapped around another organ which is smaller and looks longer. This smaller organ is the small intestine. Since we know that the large intestine wraps around the small intestine, we can infer that the organ is the large intestine.

How can using a dam as a source of freshwater also harm wildlife?
A. Dams help control floodwaters.
B. Dams provide drinking water.
C. Dams displace existing habitats.
Ο Ο
D. Dams provide water recreation.
Answer:
c
Explanation:
because its the only one that would be hurting wild life.
Using a dam as a source of freshwater can harm wildlife by displacing existing habitats. Therefore, option (C) is correct.
What are the negative impacts of dams?Dams often require the creation of reservoirs, which can submerge large areas of land and alter the natural flow of rivers and streams. This can lead to the loss of important habitats for fish, mammals, and other wildlife that rely on rivers and streams for food, shelter, and reproduction.
In addition, changes in water temperature, dissolved oxygen levels, and water flow can negatively impact aquatic ecosystems downstream from the dam.
These impacts can be mitigated through careful planning and management, such as the creation of fish ladders and other structures to help fish navigate past the dam, and the release of water at appropriate times to mimic natural flow patterns.

thinking about the components in pcr, do you think there are major differences in the process of dna replication between species?
The major difference in the process of DNA replication between species is the linear order of nucleotides, which can be amplified by PCR. This technique enables the amplification of specific DNA fragments.
The Polymerase chain reaction (PCR) is a technique widely used in molecular biology in order to amplify and thus identify small DNA fragments (approx. 1000 pb).
The PCR uses all materials required to carry out DNA replication: a thermostable DNA polymerase, primers (DNA oligonucleotides), deoxyribonucleotides (ddA, ddG, ddC, or ddT), and template DNA.
The template DNA indicates the linear order of nucleotides that will be added to the amplified DNA fragment, which is highly specific and may vary even between individuals of the same species.
