3. You are studying a population of pangolins (a scaly anteater), and you determine that there are two scale phenotypes: a thick

scale that is dominant to a thin scale. You also find that thick-scaled individuals are better able to survive encounters with predators.
What evidence would you need in order to determine if this selective advantage is changing the population? (1 point)
-The number of individuals displaying each phenotype in the current generation.
-The number of individuals displaying each phenotype in the offspring.
-The number of individuals that survive predator encounters.
-The number of individuals displaying each phenotype in both the current generation and the offspring.

When elongated, tube-shaped cells from the lining of the intestine are treated with a certain chemical, the cells sag and become
Vlada [557]

Answer:

Microtubules

Explanation:

These filament-like structures are a major component of the cytoskeleton of the cell and help is maintain asymmetrical cell shape. They are composed of tubulin molecules arranged to form a 'hollow straw' attached to the cell membrane end to end . The contraction and lengthening of these microtubules are controlled by the addition of removal these of tubulin molecules to vary its length.

a researcher wishes to know whether there is a significant difference in the number of knee injuries reported among four sports.
boyakko [2]

Answer:

Chi-square analysis cannot be used to check for significant difference in the number of knee injuries among four sports.

Explanation:

The chi-square analysis is a statistical procedure that is used to test association between measured variables or goodness of fits of a set of measured variables to expected outcomes.

<em>In the case of testing for significant difference, chi-square analysis cannot be used as testing for significant difference in two or more means requires using t-test, analysis of variance, or any other relevant statistical procedure.</em>

To compare number of knee injuries reported among four sports for significant difference, the most suitable statistical procedure would be analysis of variance.

What do studies show about temperature tolerance of intertidal animals
Rom4ik [11]

<u>Answer:</u>

<em>The intertidal zone is a region of extreme conditions and the organisms should have special mechanisms to cope up with the extreme conditions. </em>

<u>Explanation:</u>

Low tides expose an intertidal zone to air while high tides cover the intertidal zone with ocean water. When exposed to air the intertidal region is <em>directly exposed to the sun and there will be high temperature. </em>

Thus the animals have to cope up with the extreme heat and also have to face colder environment when under the sea.  <em>Since there is change in salinity the organisms have to handle this as well.</em>

Some animals with shells close their shell tightly to seal moisture. Animals like <em>snails and crabs have thick outer covering to prevent water loss by evaporation. </em>

Organisms like leaf barnacles cluster together to avoid individual exposure. <em>Animals like sea stars cling to the rocks to avoid being washed away by the waves. </em>

The Manx cat is in the domestic cat group, and the bobcat is in the lynx group. Both have a trait in common: short, stubby tails
Vanyuwa [196]

Answer: Both share common ancestry

Explanation:

Though both cats are of different groups, the presence of an ananatomical similarity - short, stubby tails - suggest strongly that they share a common ancestry i.e evolved from the same organism who had lived many years before, and possess short, stubby tails alongside other traits no longer shared by both bobcat and Manx cat

Explain how different photosynthesis modes allow plants to adapt to particular environments​
Alexxandr [17]
Autotrophs- include plants, algae, and cyanobacteria and are photosynthetic organisms. Heterotrophs- are consumers that get energy by feeding on autotrophs. Both use organic molecules produced by photosynthesis as a source of building blocks for growth and repair and as a source of chemical energy for cellular work.
