The correct answer is small hydrophobic molecules.
The smaller the molecule and the more hydrophobic, or nonpolar, it is, the more rapidly it will diffuse across a membrane. It is because of the composition of membrane (lipid bilayer). By contrast, membrane is highly impermeable to charged molecules (ions), no matter how small they are.
number 1 is not part of the theory of evolution.
Evolution is change in the heritable characteristics of biological populations over successive generations.
B. a specific place on a chromosome where a particular gene resides.
A locus (plural loci) in genetics is the position of a gene on a chromosome. Each chromosome carries many genes; humans' estimated 'haploid' protein coding genes are 19,000-20,000, on the 23 different chromosomes. A variant of the similar DNA sequence located at a given locus is called an allele.
Answer:
Deltoid
Explanation:
The muscles of the trunk and the muscles of the lower extremity will be used for stability and moving the box across the 2 meters. The muscles of the upper extremity would be used to varying degrees to lift, hold, and lift the box to sternum level and place it in its place and which muscles contribute to the specific portion of the task you intend to study will depend on the magnitude of the load, the frequency the task is completed, the velocity at which the task is completed, the height differential between where the box is lifted from to the height at which the box is placed when the task is completed.
Let's go through these one by one:
- Habitat loss is an environmental effect of farming. When vegetation is torn up to make room for a farm, the organisms living in those plants and trees are losing their homes.
- Soil erosion is an environmental effect of farming. When the vegetation native to an area is torn up and replace with domesticated crops, the topsoil is more likely to be blown away. This is because native plants will typically have longer root systems, which hold the soil down better. Erosion can also be an issue if the crops aren't planted in ideal places or are organized in the wrong way.
- Flooding is an environmental effect of farming. This can be caused by two main ways. Either the erosion that occurs doesn't leave enough soil to absorb water, leading to a flooding on the soil, or the irrigation and drainage systems have been improperly set up.
- Increased carbon dioxide (CO₂) is not an effect of farming. While there may be deforestation happening that would decrease the vegetation density of the area, a farm will have crops. These crops are just like the native vegetation, in that they will perform photosynthesis. This effectively turns CO₂ (and water and light) into oxygen and glucose (sugar). So, the overall CO₂ level will not increase.
The answer to your question in "Increased Carbon Dioxide levels".
