<h2>Answer:</h2>

<u>The property is that </u><u>water expands when it freezes and oxygen is trapped inside</u>

<h2>Explanation:</h2>

Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds. The oxygen is present in water under the ice and this oxygen is used for breathing by the marine and aquatic animals.

In garden peas, long stems are dominant to short stems, and yellow seeds are dominants to green seeds, too long/yellow pea plant
Lera25 [3.4K]

Answer:

A) 300

B) 3:1

C) 9 long yellow : 3 long green : 3 short yellow : 1 short green

Explanation:

Long stems (L_) are dominant to short stems (ll)

Yellow seeds (Y_) are dominant to green seeds (yy)

We interbred pea plants with long stems and yellow seeds (L_Y_), but they had a short green parent (llyy) that could have only produced <em>ly</em> gametes, so our plants are heterozygous <em>LlYy</em>.

C) We interbred them LlYy x LlYy. If the two genes are unlinked, this is a typical dihybrid cross and from Mendel's law of independent assortment we know that the offspring will have the following phenotypic ratios:

  • 9/16 L_Y_ (Long, yellow)
  • 3/16 L_yy (Long, green)
  • 3/16 llY_ (short, yellow)
  • 1/16 llyy (short, green)

A) 3/16 × 1600 = 300 plants will be long and green.

B)

9/16 + 3/16 = 12/16= 3/4 plants will be yellow;

3/16 + 1/16 = 4/16= 1/4 plants will be green.

The ratio will be 3 yellow : 1 green

Many anti-evolutionists believe that since science doesn't have answers for all questions; scientific conclusions are not necess
Basile [38]

Answer:

In science, accepted theories do not represent absolute truths. A scientific theory is accepted when there is much evidence available that support its statements, but new lines of evidence can modify original presumptions  

Explanation:

A scientific theory is a plausible explanation of a particular phenomenon of the natural world, which has been many times tested and verified by using the scientific method. The accepted theories are progressively modified (or even overturned) as new lines of evidence emerge. In consequence, a scientific theory is composed of statements that we consider as truths regarding the available evidence, but we have no absolute certainty that such statements are true. The ability to self-correct is fundamental in science and it happens when we discover that the original statements of a scientific theory were wrong, thereby new lines of evidence allow us to correct the error and/or develop new scientific theories.
