The dna sequence for oxytocin?

Increasing muscle mass and decreasing fat content in your body can increase ones use of energy. Why is this?

kobusy [5.1K]

Explanation:

Muscle tissue is metabolically more dynamic and burn a larger number of calories than fat tissue. The more muscles you have, the greater your resting energy expenditure, which implies that your body burns more calories while sitting idle

4) A homozygous groucho fly ( gro, bristles clumped above the eyes) is crossed with a homozygous rough fly (ro, eye abnormality)

docker41 [41]

Answer and Explanation:

A homozygous groucho fly ( gro, bristles clumped above the eyes) is crossed with a homozygous rough fly (ro, eye abnormality).

The F1 females are testcrossed, producing these offspring: groucho 518 rough 471 groucho, rough 6 wild-type 5 1000 a) What is the linkage distance between the two genes? B) Plot the genes on a map c) If the genes were unlinked and the F1 females were mated with the F1 males, what would be the offspring in the F2 generation?

1st cross:

Parental) grogro ro+ro+ x gro+gro+ roro

F1) gro+gro ro+ro

2nd cross:

Parental) gro+gro ro+ro x grogro roro

Gametes) gro+ro+ gro ro

gro+ro gro ro

gro ro+ gro ro

gro ro gro ro

Punnet square)

gro+ro+ gro+ro gro ro+ gro ro

gro ro gro+gro ro+ro gro+gro roro grogro ro+ro grogro roro

F2)

0.518 grogro ro+ro (518 individuals)

0.471 gro+gro roro (471 individuals)

0.006 grogro roro (6 individuals)

0.005 gro+gro ro+ro (5 individuals)

Total number of individuals 1000

Note: These frequencies were calculated dividing the number of individuals belonging to each genotype by the total number of individuals in the F2.

To know if two genes are linked, we must observe the progeny distribution. If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent.

In the exposed example we might verify which are the recombinant gametes produced by the F1 di-hybrid, and we can recognize them by looking at the phenotypes with lower frequencies in the progeny.

By performing this cross we know that the phenotypes with lower frequencies in the progeny are groucho, rough and wild-type. So the recombinant gametes are gro+ro+ and gro ro, while the parental gametes are gro+ro and gro ro+.

So, the genotype, in linked gene format, of the double heterozygote individual in the F1 is gro+ro/gro ro+.

To calculate the recombination frequency we will make use of the next formula: P = Recombinant number / Total of individuals. The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU).

The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.

The recombination frequency is:

P = Recombinant number / Total of individuals

P = 6 + 5 / 1000

P = 11 / 1000

P = 0.011

The genetic distance between genes, is 0.011 x 100= 1.1 MU.

Genetic Linkage Map:

Parental Phenotypes)

-----gro+------ro---- -----gro------ro+----

----- gro ------ro---- ---- gro------ ro ----

Recombinant phenotypes)

-----gro+------ro+---- -----gro------ro----

----- gro ------ ro---- -----gro------ro----

If the genes were unlinked and the F1 females were mated with the F1 males, the offspring in the F2 generation would have been

4/16 = 1/4 gro+gro ro+ro

4/16 = 1/4 gro+gro roro

4/16 = 1/4 grogro ro+ro

4/16 = 1/4 grogro roro

Their phenotypic frequencies would be 1:1:1:1 related.

How would you explain to Dr. Jackie Lewis why the rock in the Great Plains and Rocky Mountains have similar mineral compositions

densk [106]

Because of the soil the rocks are in. If They stayed in that soil for a while which affected the compounds, shifting the mineral composition.

How does geothermal energy differ from solar energy

neonofarm [45]

Solar Energy:

Of all of the solar technologies, solar thermal systems are by far the most straightforward and the best developed. Architectural Designs are being developed to conserve solar energy by taking advantage of the site and building materials which in turn transform a building into a solar collector. There are many mechanical moving parts within an active solar thermal system.

The makeup of Solar Energy Systems and how solar panels work is best described as follows:

The solar collector (basic unit) is a panel generally made from aluminium, glass, plastic and copper. These panels when fixed to a roof absorb direct sunlight and transfer heat to a fluid that passes through the collector or basic unit. This fluid then flows through pipes into the building where it then heats water or warms the rooms.

Sunlight is converted into electricity by Photovoltaics (solar cells). These solar cells produce an electromotive force in a material as a result of its absorbing ionizing radiation.

In the case of semi-conductors, significant conversion efficiencies have been achieved however in theory this effect is also apparent in solids, liquids and gases. The most commonly used component of the solar semi-conductors is Silicon.

There are a range of different solar power systems currently available. These are

Grid connect solarStand-alone or off-grid solar systemsHybrid solar systemsPortable solar power systemsSolar batteries

More information can be found about these types of systems here.

The usefulness of these Solar Cells in the Space Exploration Program has already been proven in India as well as other countries in the world. The Bhabha Atomic Research Centre in Bombay, have successfully developed Solar Cells which have been tested in the satellite Bhaskara and which also meet part of the power requirement abroad (Gupta, 1981). The likeliness for large-scale power generation to meet energy requirements on earth is even bigger.

Geothermal Energy:

Geothermal Energy is a clean and sustainable power source that comes from heat in the centre of the earth.

Hot molten rock called magma deep inside the earth’s surface has in some places pushed up towards the earth’s crust, resulting in the range of geothermal energy resources to be expanded.

Geysers are produced when water flows over these hot rocks causing steam to rise through crevices in the earth’s crust, which can then be converted into electricity.

There are three types of geothermal energy technologies:

Geothermal Electricity Production: using the earth’s heat to generate electricity.

Geothermal Direct Use: using hot water within the earth to produce heat directly.

Geothermal Heat Pumps: heating and cooling buildings using the shallow ground.

It has only recently become evident that Australia has potential for geothermal energy production, because of the perception that the resources were only found in locations that have active volcanism (which Australia doesn’t have).

However, it has been uncovered that Australia is home to suitable hot sedimentary aquifer and hot rock resources.Two projects are under development in Australia to utilise these resources, and they are hot sedimentary aquifers (HSA), and enhanced geothermal systems (EGS or hot rocks).
