Answer:
Not all DNA that was found at the scene has to be related to the scene.
Explanation:
Just because DNA was found at the scene, that doesn't mean that the person there is actually guilty. For example, in a case where person B is guilty, a strand of hair from Person A could be carried over to another scene on Persons B's clothing.
Answer:
Because DNA is more reliable than other forensics, scientists have shrugged off suggestions that it could fall victim to the vagaries of bias. But Dror noted that much DNA analysis involves interpretation. With interpretation comes subjectivity, and with subjectivity can come error. Only one-tenth of 1 percent of human DNA differs from one individual to the next and, although estimates vary, studies suggest that forensic DNA analysis is roughly 95 percent accurate.

What is crossing over in meiosis and how does it ensure genetic diversity?
Answer:

3. A few years ago the population of male blue moon butterflies on the island of
Samoa declined. One hypothesis for the decline of the male butterflies is that a
parasite infected the cells of female butterflies. The parasite was passed to
offspring through the females' eggs and killed the male butterfly embryos. At
one point during the decline, nearly all the butterflies in the population were
females, but after five years the number of males in the population increased
significantly.

In which situation would water enter a cell through omosis?
Answer:
Water moves into and out of cells by osmosis. If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic.

c. polar regions
d. deep sea
Answer:
The answer would be B. Mangrove Swamps
Explanation:
Brackish water is when freshwater meets with sewer water or salty water.
Brackish water can be found in the mangrove swamps ecosystem.
They are marked by halophytic trees, shrubs and different flora thriving in saline to saline tidal waters.
What is the mangrove swamps ecosystem?
Mangrove forests, also named mangrove swamps, mangrove shrubs or trees, are formative wetlands that appear inshore intertidal zones. Mangrove forests grow mainly in equatorial and subtropical spaces because mangrove trees cannot resist freezing .

Knowing what you know about photosynthesis, explain how the process may reduce
global warming (caused by too much carbon dioxide in the atmosphere).
Through the pores called stomata in their leaves, plants take in carbon dioxide from the atmosphere that they use for photosynthesis. ... But when carbon dioxide levels increase, plants' stomata shrink, releasing less water into the air and reducing the cooling effect.

question
A student poured a solution of bromothymol blue indicator into three test tubes. Then he placed an aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Bromothymol blue turns from blue to yellow in the presence of CO2
Predict what will happen to the test tubes in Figure 9–9 after 24 hours in the dark.
In the dark the aquatic plant won't do photosynthesis. Instead it will do cellular respiration in which it will produce CO2. Therefore after 24 hours of letting the plant in the dark introducing Bromothymol in the solution will cause it to turn yellow.
