Select all of the answers that apply. If global warming were to raise temperatures 1.5°C to 4.5°C, what would most-likely happen

? We'd get a better tan. Polar ice caps would melt, increasing sea levels. Wildlife would have to migrate or die. The ozone layer would be depleted. Hurricanes and typhoons could increase in intensity. Glaciation would occur.

Polar ice caps would melt and increase the sea level. The ozone layer would be depleted. And hurricanes are also related.

Hope it helped!

Answer:

Option A, B and , We'd get a better tan. Polar ice caps would melt, increasing sea levels. Wildlife would have to migrate or die

Explanation:

With the rise in temperature from 1.5 degree Celsius to 4.5 degree, the global temperature increases which leads to higher heat content with in the planet earth. As the heat causes tanning, the higher the heat will get , the more will be the tanning. Also Glaciers are melting due to rise in temperature which leads to rise in water level on planet earth.  

Intense heat may cause terrible living condition in the troposphere of the earth’s atmosphere due to which the wildlife will either migrate to a cooler place or they will die.  

Glaciation is caused by freezing environmental condition and thus, this option is incorrect

Ozone layer depletion leads to increase in temperature thus it is the causative agent of temperature rise, therefore it is also incorrect

Hurricanes and Typhoons may or may not get affected , therefore It is not considered a correct choice of answer.

Therefore, only option A,B and C are correct.

Answer:

A. Survive environmental changes.

Explanation:

Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.

A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).

Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms.

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

The characteristics which are consistent with the concept of natural selection includes;

I. More offspring are produced than can survive in an environment (overproduction of offspring). This ultimately implies that, the more offsprings that are reproduced by the parent organism, the more likely are they to survive.

II. There is genetic variation within populations. This simply means that there is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.

III. Organisms with beneficial variations are more likely to survive and reproduce, as well as passing on their genes to subsequent generations.

Hence, a population of living organisms with a large gene pool (gene diversification) is more favorably disposed to survive environmental changes than a species population having a small gene pool.

In conclusion, the higher the genetic makeup of a living organism, the higher are its chances of surviving environmental changes in the ecosystem.

Differentiation requires __________ of particular genes to produce populations with __________ capabilities that form tissues. d
exis [7]

Answer;

-Inactivation; limited

Differentiation requires inactivation of particular genes to produce populations with limited capabilities that form tissues.

Explanation;

-Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression.

-Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.

-Gene expression plays a critical role in the morphological changes that take place in a developing embryo and fetus and in the differentiation of stem cells to form specialized cells.

The following question is based on information from Frank M. Frey, "Opposing Natural Selection from Herbivores and Pathogens May
SSSSS [86.1K]

Answer:

The correct answer is option d)"the percentage of pink flowers should increase over time".

Explanation:

In this study it is stated that two factors affect the flower coloration of <em>Claytonia virginica</em>: slugs preference of eating pink-flowering plants and bees preference of pollinating pink-flowering plants as well. If the researcher removes all slugs from the study population we can expect that the percentage of pink flowers should increase over time. The removal of the predator that prefers eating pink-flowering plants will favor the reproduction of this type of plants, which are also favored by bees pollination preference.
