Our DNA is over 99% identical, but why would only 38% of us get cancer?
our genes some genes are more prone to cancer then others
(I'm pretty sure)
Cancer occurs during mitosis as a result of a mutation in the genes. The thing is, not everyone's genes mutate the same way therefore not everyone will have cancer. Also, mutations are completely random and one mutation will not be enough to cause cancer. This is why although our DNA is identical, not everyone has cancer or has the same type of cancer.

explain what would happen to an animal if the vegetation around them disappeared ??
Answer:
If the vegetation around them disappeared all life requiring oxygen would die. Life means sun, water, and green plants. This is practically impossible to disappear all plants without cosmic accident. If that happens then all animal kingdoms will die simultaneously.
Explanation:
Vegetation is the source of energy for all organisms. All other organisms directly or indirectly depend on them for food. So, if all the green plants disappear from the earth, all the herbivores will die due to starvation and so will the carnivore, i.e., it would result in the extinction of life from the earth.
If you have any questions please ask!
Animals will begin to die if the vegetation around them disappeared.
What is Vegetation?These are referred to as plants and are the autotrophs in the ecosystem
because they manufacture their food through photosynthesis.
During photosynthesis, the food and oxygen produced serve as major
sources in which animals which is needed for activities and survival.
Absence of them will lead to the death of the animals.

Describe how the water vascular system helps a sea star move around.
Locomotion: Sea stars move using a water vascular system. Water comes into the system via the madreporite. The radial canals carry water to the ampullae and provide suction to the tube feet. The tube feet latch on to surfaces and move in a wave, with one body section attaching to the surfaces as another releases.
Answer:
Locomotion: Sea stars move using a water vascular system. Water comes into the system via the madreporite. ... The radial canals carry water to the ampullae and provide suction to the tube feet. The tube feet latch on to surfaces and move in a wave, with one body section attaching to the surfaces as another releases.
Water travels from sieve plate> store canal> ring canal> radial canal> ampullae> tube feet, the tube feet has tiny suctions on the bottom to help it move.
Each sea star had hundreds of tiny feet on the bottom of each ray. ... By moving water from the vascular system into the tiny feet, the sea star can make a foot move by expanding it. This is how sea stars move around. Muscles within the feet are used to retract them.
A sea star moves by regulation of its water vascular system. Tube feet attach to a surface, the sea star moves itself forward. ... Larval echinoderms are bilaterally symmetrical, whereas adult echinoderms are radially symmetrical.

Throughout the 1900s, many large dams were constructed along river systems throughout the United States. These dams have disrupted the flow of fresh water and sediments into coastal ecosystems. Such disruptions have lead to ecosystem disturbances and biodiversity loss.
Many dams no longer in use are being removed from river systems in an effort to counteract the biodiversity losses they had caused. To evaluate how effectively dam removal reverses biodiversity loss, scientists monitored biological and physiological parameters at 16 sites in a coastal ecosystem in the three years following the removal of two dams. These dams were located on the same river that emptied into the Pacific Ocean. The removal of these two dams occurred from 2011 to 2012.
Following the removal of the dams, the scientists recorded an influx of sediment into the coastal ecosystem at the mouth of the river. This influx persisted through the year 2014, the end of the study period. Over this period, four of the offshore sites were covered by between 10 cm and 13 m of sediment, while the remaining 12 sites had no discernible change in sedimentation along the seafloor. All sites exhibited an increase in the turbidity, or cloudiness, of the water within the first year after dam removal. Sites at the mouth of the river exhibited an increase in turbidity that continued through 2014.
Each year, the researchers recorded the median number of algae and invertebrate species at sites in which sediment deposition had and had not changed. The table below shows these results.
Based on the findings above, which of the following strategies would be most likely to improve biodiversity recovery following dam removal?
A.
A smaller dam should be installed at the mouth of a river in which a dam is to be removed in order to decrease the likelihood of sediment deposition in coastal ecosystems.
B.
New species of algae should be added to the mouth of a river a year after dam removal in order to increase the biodiversity of algae in the downriver ecosystem.
C.
Sediments should be deposited along the seafloor in the year prior to dam removal in order to increase the biodiversity of invertebrates at sites along the coast.
D.
Sediment that has built up behind a dam should be cleared out before the dam is removed in order to decrease the risk that
Answer: D
Explanation:
Dams change the way rivers function. They can trap sediment, burying rock riverbeds where fish spawn.
Gravel, logs, and other important food and habitat features can also become trapped behind dams. This negatively affects the creation and maintenance of more complex habitat (e.g., riffles, pools) downstream.
Dams that divert water for power and other uses also remove water needed for healthy in-stream ecosystems. Peaking power operations can cause dramatic changes in reservoir water levels. This can leave stretches below dams completely de-watered.
Answer:
AHH i think its A (dont get angry with me if its not i tried my best)
Explanation:
It shows that in the graph that the two species did better when no deposition was increased, the species preferred less deposition and could thrive better without it. So choice A gives a smaller dam to DECREASE the chance of deposition (less deposition = happier species based on the graph) and there for would improve biodiversity.

How might upward growth of cities be a better choice than outward growth? a. Upward growth affects less land area than outward growth. B. Upward growth helps moderate pollution problems. C. Upward growth has no limitations. D. Upward growth has no environmental impact. Please select the best answer from the choices provided A B C D.
Growth is an expansion of the land and infrastructure of a specified region. It can be upward or outward. The upward growth is a vertical development of the infrastructure rather than expanding the construction over the large area as an outward growth.
Upward growth affects less land area than outward growth.
What are the advantages of the growth of cities?The upward development of metropolia can be more suitable for the environment than outward expansion. Exterior development adds to habitat threat and loss of natural sources in the surrounding region. Upward development does not infringe on the surrounding habitat, however cannot control the production of waste and contaminants.Therefore, option a. is correct.

Taft appointed a secretary of the interior who was neutral on conservation.
Answer:
Taft appointed a secretary of the interior who undid some of Roosevelt’s conservation work.
Explanation:
From Roosevelt's guidance, Taft had the little opponent for the Democratic appointment for the administrator in 1908 and easily destroyed William Jennings Bryan for the administration that November. In the White House, he concentrated on East Asia more than European interests and regularly occurred to prop up or eliminate Latin American powers. Taft asked decreases to trade charges, then a major cause of national revenue, but the resulting proposal was massively affected by special matters.
