Answers

D high turbidity, that’s muddy looking water

The water in a lake is not safe for drinking, high turbidity levels in the lake​ Coliform bacteria occur innately in soil and in the intestines of humans and other organism.

What is dissolved oxygen in water?

Dissolved oxygen (DO) is the quantity of oxygen that is current in water.

Water bodies obtain oxygen from the atmosphere and from aquatic plants.

Rushing water, such as that of a fast moving stream, dissolves more oxygen than the still water of a pond or lake

Thus, option "D" is correct, high turbidity levels in the lake​.

Move the bonfire to the left side of the sand. Observe how the smoke from the bonfire moves"" Dose anyone know how to get past this?

Answers

Fire requires three things heat, fuel, and oxygen. The heat source is a match. The firewood burns and provides its own heat to keep it burning.  Fire needs oxygen, which can be obtained from fresh air. Air gets hot and denser.

When fire burns, heat transfers kinetic energy to the molecules. As the kinetic energy increases, there are more collisions between molecules. The hot air becomes less dense. As less dense than the cold air around it, the hot air rises and carries the smoke with it. Therefore, the smoke moves away with the wind.

The bacterium responsible for the disease had never before been known to be pathogenic. From your knowledge of bacterial genetics, can you postulate how it might have acquired the ability to cause disease

Answers

Answer:

Evolution.

Explanation:

It might have acquired the ability to cause disease due to evolution. Due to evolution, the harmless bacteria can turn into infectious pathogens that cause diseases. Evolution is the change in the characteristics of a species over several generations due to the process of natural selection. This evolution in the bacteria occurs due to changing of environmental conditions which changes the genetic makeup of that harmless bacteria and turn into infectious pathogen.

The graphs here show the distribution of beak depths for the ground
finches on Daphne Major, an island in the Galapagos. The bird beaks were
measured over a multi-year study, including a time period before and after
a drought. The drought reduced the supply of seeds and left most of the
seeds as thick-walled nuts that survived the drought. Analyze the data and
select the claim about natural selection and genetic diversity that is
supported by the data.

Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select for the most fit phenotypes, as there was an
increase in average beak depth after the drought.

Natural selection tends to increase genetic variation, as there were more ground
finches after the drought, and it tends to select for the most fit phenotypes, as there
was an increase in average beak depth after the drought.

Natural selection tends to reduce genetic variation, as there was a smaller distribution

Answer: (A) Natural selection tend to reduce genetic variation as there was a smaller distribution of beak depths, but it tends to select for the most fit phenotypes, as there was an increase in average beak depth after the drought.

Explanation: The picture below shows proof if needed. On USATP

Natural selection tend to reduce genetic variation as a smaller allocation of beak depths, but it tends to select for the most fit phenotypes, as an increase in average beak depth after the drought.

How does natural selection affect genetic variation?

Genetic variations that vary gene and protein role.

If a trait is favourable and helps the someone survive and breed, the genetic variation is more likely to be passed to the next generation.

Which of the following defines an ecological succession? A.It is the final and stable commuity of an ecosystem. B. It is the first plants and animals to inhabit a newly available ecosystem. C. It is the number of a particular species that an ecosystem can support. D.It is a process of chang during which species in a community are established or replaced.

Answers

Answer:

D. It is a process of change during which species in a community are established or replaced

Explanation:

Ecological succession is a process that occurs when a community is being established or replaced.

It shows the change in community over time, focusing on the types of plants and the maturity of plants that are in the community.

Primary and secondary succession are the two types of succession. Primary succession shows the process of change in the establishment of a community. Secondary succession shows the change when a community is being replaced.

So, the correct answer is D. It is a process of change during which species in a community are established or replaced

Large and small particles are found mixed in a fast-moving stream. What type of erosion is this?
A. Suspended load
B. Traction load
C. Dissolved load
D. Bed load

Answers

I think the answer is bed load

Explanation:

bed load describes particles in a flowing liquid that is transported along the stream bed

A bed load includes large and small particles are found mixed in a fast-moving stream. The correct option is D.

What is a bed load?

The descriptor bed load or bedload refers to particulate in a flowing fluid basically water that are carried anywhere along stream bed. Bed load works in tandem with suspended load and wash load.

Conventionally, parameters of bedload have been taken by placing samplers in contact with the bed and permitting the sediment transferred as bedload to accrue (or be trapped) inside the sampler for a certain amount of time before raising the sampler to the surface and emptying the material.

Once the critical boundary shear stress is exceeded, coarser grained material tends to move in intermittent contact with the bed.

This movement, known colloquially as "bedload transport,"

Thus, the correct option is D.
