Which is a pollutant associated with high-tech gadgets in landfills?
Answer:
Lead is the major pollutants of high-tech gadgets, occupying 40%, while other metals 75%.This is because Pb forms lager components of these gadgets.For example a desktop computer contains about 10 pounds of Pb.
The lead to recycle these material to prevent pollution is important.
Explanation:
Answer:
Heavy metals such as plumb, mercury, arsenic, etcetera.
Explanation:
There are many heavy metals used in high-tech gadgets, such as mercury, cadmium, arsenic, among others.
The pollution produced by industries, technology, agriculture, mining industry, and the indiscriminate use of fertilizers and other chemicals on land is increasing the amounts of heavy metals. These substances are incorporated in rivers, lakes, underground water, vegetables, and animals. These pollutants alter the trophic chain
sustainability creating potential risks in nature and societies, because of the problems to human and animal health.
How is cancer related to mutations? How is it related to the cell cycle?
Answer:
Cancer is related to the cell cycle bc, cancer cells mutate. Cancer is unchecked cell growth. Mutations in genes can cause cancer by making cell division rates go up faster or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor

Explain why a swing will not stay in motion forever after you have given it a push. What happens to the mechanical energy of the swing?
Explanation:
As the pendulum swings back and forth, the balance between the two types of energy changes constantly. At some points in its swing, the pendulum has more kinetic energy. At other points, it has more potential energy. ... No pendulum can swing forever because the system loses energy on account of friction.
how does the bone matrix differ from the matrix of cartilage
Answer:
Cartilage and Bone are specialized forms of connective tissue. They are both made up of cells embedded in an extracellular matrix. Cartilage is thin, avascular, flexible and resistant to compressive forces. Bone is highly vascularize, and its calcified matrix makes it very strong.

What cell structure is responsible for regulating all cellular activities?
Choose 1 answer:
A. Nucleus
B. Mitochondria
C. Lysosome
D. Golgi body
Answer:
Let me know if this is right Answer: Nucleus
Explanation:
This organelle known as the Nucleus has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
Answer:
Lysosome
Explanation:
The lysosome is the cell’s recycling center. These organelles are spheres full of enzymes ready to hydrolyze, (chop up the chemical bonds of) whatever substance crosses the membrane, so the cell can reuse the raw material. These disposal enzymes only function properly in environments with a pH level of 5, two orders of magnitude more acidic than the cell’s internal pH level of 7. Lysosomal proteins only being active in an acidic environment acts as safety mechanism for the rest of the cell - if the lysosome were to somehow leak or burst, the degradative enzymes would inactivate before they chopped up proteins the cell still needed.

We interviewed 3 students about what they thought were the reasons for the change in Guppy population and this is what they said:
● Norise says the change in the guppy population was caused by a mutation.
● Lauren says the change was caused by a change in the environment.
● Megan thinks both Norise and Lauren are correct.
Who do you think is right? Explain what happened to the guppies over many generations.
Use multiple pieces of evidence of the notes in your answer to receive full credit.
Answer:
Answer:
Megan is right.
Explanation:
The guppy is a very adaptable freshwater fish, commonly found in aquariums world wide. The success of the guppy is mostly due to its ability to adapt to the changes in its environment. Guppies were originally found in the southern american continents and the Caribbean island, but has been exported all over the world, first as a means of curbing the spread of mosquitoes by feeding on the larvae and then as a pet. Over time, guppies have found themselves in diverse environment, and some have undergone mutation of body parts just to adapt. So, the need for adaptation to their constantly changing environment has led to mutation in the guppies.

Answer:
Transcription is the process in which a gene's DNA sequence is copied (transcribed) to make an RNA molecule.
Explanation:
Transcription uses one of the two exposed DNA strands as a template; this strand is called the template strand. The RNA product is complementary to the template strand and is almost identical to the other DNA strand, called the nontemplate (or coding) strand.

Some organisms seem to have undergone very little evolutionary change
over huge spans of geologic time. One example is the shark. Shark
ancestry dates back around 425 million years, which is about 200 million
years before the earliest known dinosaur. In all, abut 2000 to 3000
species of fossil sharks have been documented. About 1100 species of
shark remain on Earth today. These sharks represent an ancient life form.
Why do you think the rate of evolution of the shark has been so gradual?

Are the finches that Charles Darwin studied on the Galápagos Islands an example of divergent evolution or convergent evolution? Give two point to explain your thinking.
Answer:
shark are slow evolving species because of lower gene flow and rate if reproduction.
Darwin finches undergo divergent evolution
Explanation:
Sharks have evolved slowly because of following reasons –
a) Lower rate of reproduction
b) Restricted gene flow because of isolated habitat such as stretches of deep water
c) Staying close to the eggs and hence guarding them throughout their life thereby allowing no cross mating.
d) Lower rate of mitochondrial DNA (mtDNA) evolution
Darwin’s finches show divergent evolution as different species of finches originated from a common ancestors. The beak size of finches vary form one species to other because of different diet habits
