Bias.

A major cigarette company wouldn't want their sales to go down so they'd publish a <em>biased</em> study claiming there's no link between cigarettes and cancer.

How might mutations introduce variation into a population
Mazyrski [523]
A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations. Gene flow is any movement of genes from onepopulation to another and is an important source of genetic variation.

All the following are true of the movement of Earth's atmosphere except :
zheka24 [161]

Answer:

All  are true of the movement of Earth's atmosphere except :

d. Warm air is less dense than cool air so it tends to sink towards the Earth's Surface.

Explanation:

  • When gases heat up, their volume increases and  density decrease.
  • A decrease in density causes a substance to become lighter.
  • Thus, when air warms up due to heat from the sun its density decreases and it gets lighter.
  • So, it will move up.
  • The Cooler air in turn is denser and heavier so it will sink towards the Earth's surface.
  • Hence, the statement d , which states that 'warm air is less dense than cool air so in tends to sink towards the Earth's Surface' is FALSE.

A large-mouth bass is taken from a fresh water lake and transplanted into the river. If the conditions for survival are optimal,
liberstina [14]
The cells will make some sort of reaction, there's no doubt about it. But for a bass I believe that their cells will stay the same or shrink over time.
Bass are strong fish and they usually do well when there's a change in conditions made in the environment. But it depends on what this river has in it and if it leads to bigger opened waters.
If there's a shortage of food sources for the bass it'll have to adapt quickly or it'll die from the predators in the area. If there isn't any places the Bass can lay their eggs (reproduce) its population will die in that river.
There also competition. In that river it could have socked eye salmon in it or catfish even pikes. So the Bass cells would stay the same.

svp [43]

Answer:Phaeophyta--Described as "hairy" in appearance produce alginic acid, which can be used as a thickening agent.

Rhodophyta ;are utilized commercially to produce carrageenan and can photosynthesize at depths greater than 10 meters

Chlorophyta;Considered the progenitor of land plants, have 18S rRNA sequences comparable to plants

Chrysophyta;The is a diverse group that includes the diatoms, a major component of phytoplankton

Explanation:algae are a diverse group of organisms with majority of them living in water and a few on land. They are green and contains chlorophyll.they also contains phycobillins pigments.

Chlorophyta are green algae that exist in water habitat an example is Chlamydomanas reinhardi.they have similar structures with higher plants such as chlorophyll, cellulose cell wall and stores food as starch.

The chrysophyta includes diatoms.diatoms have a cell wall composed of pectin and deposits of silica. They may occur in large deposit as diatomaceous earth.

Phaeophyta--are brown algae. An example is sea weed they are found in deeper ocean waters. Sea weed has a thallus which branches into a basal holdfast that aids attachment to rocks.their blade allows the plant to float

Rhodophyta are algae which are sometimes Unicellular in form they have a characteristic red color due to the presence of phycoerythrin along with phycocyanin, chlorophyll.they are used as source of algar for microorganism culture.
