Answer:

coarse texture

Explanation:

when molten material is underground it's called magma. Magma is below Earth's surface so it cools slowly. The slower it cools, the more time the crystals have to expand. Big crystals result in a coarse texture.

When magma reaches the surface it becomes lava, rocks formed from lava (lava is on the surface) cool faster leaving the crystals with very little time to expand. small crystals result in a fine texture.

hope this helps :)

If a field population started with 50% standard (YY) plants and 50% yellow-green (yy) plants, how would you expect the frequenci

maria [59]

Answer:

when we obtain a 1: 1 ratio, in which the population is based on plants "Yy" and "yy", it is expected that the allele Y will predominate in number with each generation, in this way it can be predicted that the frequency would change to be of plants "YY" to 90% and 10% of plants "yy", a process called natural selection, so plants with many flowers and leaves will prevail, as well as the highest, becoming a cycle in which the Y allele, due to its characteristics, will become more competitive and successful to reproduce.

3. You were given with the following reagents; A, B, C, and D while doing differential staining. A was red, B pink, C colorless,

castortr0y [4]

a The nature of A and D is their ionic properties and as a result of their iron content.

b. They represent microscopic examination

c .Gram positives take the purple color Gram negatives take the pink color.

d. The reagent is acetone alcohol, because it causes shrinkage of the peptidoglycan layer.

<h3>What is differential staining?</h3>

Differential staining is a staining process which involves the use of more than one chemical stain.

The use of multiple stains allows for better differentiation between different microorganisms or structures/cellular components of a single organism.

a. The nature of A and D might be their ionic properties and this could be as a result of high content of Iron.

b. Reagents in gram staining represent differential stains used for the microscopic examination of bacterial cultures and laboratory specimens.

c. The appearance of gram positive is purple and gram negative is pink

Gram positives take the color of the primary stain during gram staining which is crystal violet- purple

Gram positive take the color of the secondary stain which is safranin- pink

d. The colorless reagent which is the acetone alcohol should not exceed the recommended time because it would dehydrate and shrink the peptidoglycan layer of the bacteria leading to a false result.

Summarize the cellular respiration

Sedaia [141]

Answer:

Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
