The tendency of an organism to reproduce and survive in the environment in which they thrive is termed as fitness of that organism.
• The mice are considered to be the second most successful mammal on the planet today.
• Mice possesses the tendency to change with the stresses and environment in which they thrive.
• Due to their close association with humans, house mice possess the tendency to live in very dry or hot conditions or in very cold conditions where they could not survive alone.
• The mice possesses the tendency to reproduce at a very high rate, thus, there are always individuals, which can survive.
• They have the tendency to sense their surroundings like other mammals, they even possess good hearing and vision.
• They have large cup shaped ears, which assists them to sense vibrations of sound.
• They also possess good sense of smell and whiskers that helps them to feel air movements and feel surface textures.
Thus, mice are equipped with several elements that helps them to adapt in the environment in which they live, that is, have increased fitness level.

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

Which of the following are accessory organs within the digestive system? (please select ALL that apply) *
Stomach
Large Intestine
Liver
Pancreas
Rectum
all of them are the part of digestive system
Liver and pancreas are the accessory organs within the digestive system.Thus, the correct options are liver and pancreas.
The human digestive system is made up of the gastrointestinal tract and the accessory organs which are needed for digestion . Digestion involves the breakdown of food into smaller parts, until they the food is absorbed and assimilated into the body. The process of digestion takes place in three stages: the cephalic phase, the gastric phase, and the intestinal phase.
The primary organs of the digestive system include organs like stomach,large intestine and rectum.Thus, the accessory organs within the digestive system are liver and pancreas.

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.
whats primary succession and when does it occur
Answer:
Primary succession is ecological succession that begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life (because of recent lava flows, newly formed sand dunes, or rocks left from a retreating glacier).
The Fast Plants® shown below follow the same genetic rules as the plants in the Gizmo. What is wrong with this picture?
Answer:
A
Explanation:
The genotypic mix of the two genes, or alleles, that make up an expressed trait is what causes it. Additionally, a specific gene produces a distinct protein that establishes an individual's physical traits. This is how traits are controlled by genes. Thus, option A is correct.
What is the effect of genetic rules in the Gizmo?The genotype, or set of genes an organism acquired from its parents, is ultimately responsible for the qualities that creature manifests. Each chromosome in an animal has two copies, one from each parent.
Cloning and fingerprinting are two potential applications for DNA-based identification technology.
Device Warm-Up DNA profiling compares more than just one person's full genome to another. Instead, only one specific section of the DNA is compared.
Therefore, parent 1 plant is wrong in the picture.

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

how has climate change affected ocean levels
Answer:
Climate change has caused ocean levels to rise higher.
Explanation:
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
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.

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.
