Less distance may be traveled with grains whose sizes are greater and more erratic. This is because as a stream moves downstream, its velocity progressively diminishes, causing the big and irregular grains to settle the first, hence option 3 is correct.

Both a reduction in particle size and rounding of initially angular pieces are effects of the protracted transport of material by water and wind current. The grains get smaller and more spherical the farther they have to travel.

Erosion, transport, and deposition all result in the formation of sedimentary rocks. A sediment's grain size provides crucial details on (1) the agent that caused the erosion/transport of the sediment and (2) the current's speed.

Therefore, as a stream moves downstream, its velocity progressively diminishes, causing the big and irregular grains to settle the first, hence option 3 is correct.

Answer:

The proportion of plants with deep flowers in future generations will decrease and will be very low.

Explanation:

To analyze this, we need to keep in mind the pollination process and the following general ideas:

In this particular environment, long-tongued bees used to visit plants with deep flowers to get their nectar. They used to get in contact with mature stamens and carry the pollen on their bodies to the next flower. During this process, long-tongued bees were able to ensure pollination and helped to keep a high reproductive rate of plants with deep flowers.

When shorted-tongue bees arrived at this environment, they were able to replace long-tongued bees. They also looked for the nectar of deep flowers, but instead of visiting them from the top, they were adapted to obtain nectar by drilling holes in the flower base. In this way, they missed the contact with mature stamens and pollen.

Long-tongued bees disappear, and short-tongued bees did not play a role in the pollination process of deep flowers, then the reproductive rate of these vegetable species probably started to decline.

Probably, with time, the proportion of plants with deep flowers in an environment dominated by short-tongued bees will be very low.

The proportion of plants with deep flowers in future generations will decline if bees with short tongues replace bees with long tongues.

Anything which is present in the surrounding of an organism is called its environment. It may consist of Biotic and abiotic factors.

Bees with short tongues are able to obtain nectar from deep flowers by drilling holes in the base of the flower without visiting the top of the flower. In this way, such bees are not in contact with mature stamen and pollen. Therefore, they will not play an effective role in pollination. And if such bees are replaced with long tongues bees, there will never be a deep flower obtained. Deep flowers are obtained by long-tongued bees because they take nectar from the top side and with it they also take mature stamen and pollen to perform successful pollination.

Therefore, the proportion of plants with deep flowers in future generations will decline, if bees with short tongues replace bees with long tongues.

Answer: pH = 9.4

Explanation: in water, -log(molar concentration OH-) + -log(molar concentration H+) = 14

-log(H+) is pH

so pH = 14 - -log(OH-)

= 14 - -log(2.4*10^-5)

= 14 - 4.6

= 9.4

Answer:

A. Tap water is a homogenous mixture and distilled water is a pure substance.

Explanation:

Tap water can be classified as a homogeneous mixture because it contains equal amounts of dissolved minerals and other chemicals that are even throughout the mixture.

In the other hand, distilled water is classified as a pure substance because it contains definite amount of atoms of elements and unique chemical properties that forms water.

In fruit flies, the recessive pr and cn mutations cause brown and bright-red eyes, respectively (wild-type flies have brick-red eyes). The double mutant pr cn combination has orange eyes. A female who has wild-type eyes is crossed to an orange-eyed male. Their progeny have the following distribution of eye colors:

The F1 mother of these progeny (F2) resulted from a cross between two flies from true breeding lines (P generation). What are the genotypes of these two lines ?

Answer:

prprcn+cn+ and pr+pr+cncn

Explanation:

Progeny is the offspring or descendants of any animal, plant, human or a species.

In the context, it is given that the cn mutation and recessive pr in the fruit flies makes brown and bright red color eyes. And the double mutant of pr and cn combination makes orange eyes. An oragne eye males is crossed with a female having a wild type eyes. Now for this, the F1 mother of the progeny F2 which results from the cross of two flies, the genotypes is " prprcn+cn+ and pr+pr+cncn. "

Answer:

Scanning electron microscope and electron microscope.

Explanation:

Scanning electron microscope is a type of microscope which can produced the image of cilia. Electron microscope  is a type of microscope would be the best for studying cilia because it has higher magnification power i. e.  10,000,000x, which able us to study different parts of cilia so we can say that electron microscope is the right choice for studying cilia.
