For a species with a diploid number of 26, indicate how many chromosomes will be present in the somatic nuclei of individuals th
zhuklara [117]

Answer:

<h2>Haploid=13</h2><h2>triploid=39 </h2><h2>tetraploid=52</h2><h2>trisomic=14 </h2><h2>monosomic=12</h2>

Explanation:

Given;

A species with a diploid number of 26,  so 26= 2n ( a diploid cell),

so in haploid condition, chromosome number becomes half (13 in this case). triplod is when 2n + n, and 2n +2n ( tetploid). Trisomy and monosomy is the addition or deletion of a sinlge chromosome of a sinlge set  .

Haploid=13, one chromosome from each pair of chromosome set,

triploid=39 (13× 3); diploid+ n( 3n)

tetraploid=52 (13× 4) 4n

trisomic=14 (13+1) ; n+1

monosomic=12 (13-1); n-1

Answer: anthropochory (human dispersal)

Explanation:

Assuming that the bird pollinators were significantly diminished, human dispersal will be a useful means of dispersal. Currently, in the tropics, Jatropha is intentionally planted by individuals for oil production.

Describes how energy is produced from the power of water. In your answer, include the terms: ocean water, turbine, electricity,
lapo4ka [179]

Most hydroelectric power plants have a dam and a reservoir. These structures may obstruct fish migration and affect their populations. Operating a hydroelectric power plant may also change the water temperature and the river's flow. These changes may harm native plants and animals in the river and on land. Reservoirs may cover people's homes, important natural areas, agricultural land, and archaeological sites. So building dams can require relocating people. Methane, a strong greenhouse gas, may also form in some reservoirs and be emitted to the atmosphere. Reservoir construction is "drying up" in the United States  Gosh, hydroelectric power sounds great -- so why don't we use it to produce all of our power? Mainly because you need lots of water and a lot of land where you can build a dam and reservoir, which all takes a LOT of money, time, and construction. In fact, most of the good spots to locate hydro plants have already been taken. In the early part of the century hydroelectric plants supplied a bit less than one-half of the nation's power, but the number is down to about 10 percent today. The trend for the future will probably be to build small-scale hydro plants that can generate electricity for a single community.  As this chart shows, the construction of surface reservoirs has slowed considerably in recent years. In the middle of the 20th Century, when urbanization was occurring at a rapid rate, many reservoirs were constructed to serve peoples' rising demand for water and power. Since  Hydroelectric energy is produced by the force of falling water. The capacity to produce this energy is dependent on both the available flow and the height from which it falls. Building up behind a high dam, water accumulates potential energy. This is transformed into mechanical energy when the water rushes down the sluice and strikes the rotary blades of turbine. The turbine's rotation spins electromagnets which generate current in stationary coils of wire. Finally, the current is put through a transformer where the voltage is increased for long distance transmission over power lines.   Hydroelectric-power production in the United States and the world!

When heterotrophs consume food (organic compounds), they convert it to usable chemical energy, primarily in the form of _______,
luda_lava [24]

Answer:

The correct answer is - ATP , glycolysis.

Explanation:

Heterotrophs are the organism, depends on other organisms for their food and energy. They get their energy when they take their food (glucose or other organic compound).

This organic compound is convert into the chemical energy or energy currency primarily, ATP during the process of glycolysis, the first stage or cycle of cellular respiration.

Thus, the correct answer is : ATP, glycolysis.
