Explanation:
Why is DNA in the world?
Answer: Nine years ago I jumped at an opportunity to join the international team that was identifying the sequence of DNA bases, or “letters,” in the genome of the common chimpanzee (Pan troglodytes). As a biostatistician with a long-standing interest in human origins, I was eager to line up the human DNA sequence next to that of our closest living relative and take stock. A humbling truth emerged: our DNA blueprints are nearly 99 percent identical to theirs. That is, of the three billion letters that make up the human genome, only 15 million of them—less than 1 percent—have changed in the six million years or so since the human and chimp lineages diverged.
Evolutionary theory holds that the vast majority of these changes had little or no effect on our biology. But somewhere among those roughly 15 million bases lay the differences that made us human. I was determined to find them. Since then, I and others have made tantalizing progress in identifying a number of DNA sequences that set us apart from chimps.

WILL MARK BRAINLIEST!!!! Can someone help me with this question?
What observations did scientists make when they collected and dissected rockfish?
Answer:
Rockfish larvae are pelagic, there is genetic evidence for limited dispersal within Puget Sound for the quillback and copper (S. caurinus) rockfish (Seeb 1998) as well as for differentiation from coastal populations of brown rockfish (S. auriculatus) (Buonaccorsi et al. 2002). This degree of population structure is consistent with other genetic and otolith studies from coastal Pacific rockfish populations
Answer:
Rockfish larvae are pelagic

Traditional chemotherapy drugs target cell processes that then halts cell division or results in cell death. Thus, these drugs are cell poisons, causing multiple side effects. List some of the cell processes that these Drugs often target
Answer:
Cell division
Replication
Explanation:
Traditional chemotherapy drugs target cell metabolic processes which enabled it to thrive under certain conditions and then halts such processes such as cell division or results in cell death.
Thus, these drugs are cell poisons, causing multiple side effects. Some of the other cell processes that these cells target also include replication and motility.
Which statement identifies an example of a genetic factor that could influence the growth or development of an organism created by an environmental factor? the lack of available sunlight for a small sapling to grow an increased amount of rain causing flooding in a local river fertilizer creating a mutation among a farmer's crops overcrowding of a local deer population resulting in fewer resources available
Answer:
fertilizer creating a mutation among a farmer's crops
Explanation:
A genetic factor is one that affects the gene or genome of an individual organism. This genetic factor often influences the observable trait called PHENOTYPE of the organism. In this case, an example of a genetic factor that could influence the growth or development of an organism created by an environmental factor is the "fertilizer creating a mutation among a farmer's crops"
The fertilizer represents the environmental/chemical factor which is creating the genetic factor (mutation) that will eventually influence the growth or development of the crops.
Why are Acacia Trees dependent on Giraffes?
Answer:
One study found the growth of acacia trees depended on herbivores. When the trees were protected from herbivores, including the giraffe, they produced less nectar. It turns out they this nectar provided food for ants who defended them from pests like wood-boring beetles. Also Giraffe's eat the tree seeds and when they defecate the seeds fall into new places, growing more trees.
Explanation:
The select the complementary DNA strand for the strand provided-AACTCGGAT
-GGTCTAAGC
or

List the structure(s) that form the boundary between the inside and the outside of each cell in
Model 2.
Answer:
Explanation:
An animal cell has a cellular membrane, which keeps its contents inside, differentiating the inside from the outside. A plant cell has both a cellular membrane and a cell wall, which keeps its shape and prevents it from going through lysis and cellular destruction
tl;dr
Animal cell: cell membrane
Plant cell: cell wall, cell membrane

what is fart? explain and what do you call it?
Answer:
Farts — also called flatus (say: FLAY-tuss) or intestinal (say: in-TESS-tuh-null) gas — are made of, well, gas! When you eat, you don't swallow just your food. All of these gases in the digestive system have to escape somehow, so they come out as farts! Gases are also what can make farts smell bad.
With respect to energy, Earth is a........
closed system
Integrated system
layered system
open system
why is it important to ask questions
Answer:
It helps you uncover the challenges you're facing and generate better solutions to solve those problems. We're all spending too much time and energy solving the first iteration of a challenge with the first idea we have. That's both limiting and counterproductive.
