Answer:

For every gene, there may be several possible versions. Different genes carry instructions for making different proteins. If the gene copies are heterozygous, two types of protein are produced, if the gene copies are h0m0zyg0us, one type of protein is produced.

Answer:

It may mean that the two proteins evolve in slightly different directions, so that one version works better in one set of conditions and the other under different conditions.

Please note that the cost to the organism of making two proteins instead of one is minimal. Basically, it involves adding one coding gene to the tens of thousands of genes that are already there (assuming that the sum of the amounts of the two proteins is about the same as the amount of the original one protein).

Different versions of the same protein may also be made by differential splicing of the mRNA, or by the many mechanisms of post-translational modification.

Answer:

Type II alveolar cells.

Explanation:

Type II alveolar cells produce and secrete pulmonary surfactant, a liquid with phospholipids that reduces the surface tension avoiding the collapsing of the alveoli walls and making possible the entrance off air to the alveolar sac in order to exchange O₂ for CO₂.

How do organisms get their DNA?

Reil [10]

<h2>Answer </h2>

DNA are found in the cells of all living organisms

Explanation

DNA is a complex molecule consisting of many components which are passed from parent organisms to their offsprings during the process of reproduction. The DNA contains instruction needed for an organism to develop survive and reproduce. DNA is deoxyribonucleic acid and is contained in your body's cells. From microscopic view they are double, large cable of particles termed as nucleotides. This show the cell what proteins to produce in the living organism. Hence, all living things have DNA within their cells.

What effects climate on a local scale?

max2010maxim [7]

Answer: Climate change is a long-term shift in global or regional climate patterns. Often climate change refers specifically to the rise in global temperatures from the mid-20th century to present,natural accidents and humans, can cause changes in Earth's energy balance, including: Variations in the sun's energy reaching Earth. Changes in the reflectivity of Earth's atmosphere and surface. Changes in the greenhouse effect, which affects the amount of heat retained by Earth's atmosphere and Volcanic eruptions can affect climate change, First, they release the greenhouse gas carbon dioxide, contributing to warming of the atmosphere. But the effect is very small. Emissions from volcanoes since 1750 are thought to be at least 100 times smaller than those from fossil fuel burning.
