Answer:

Thermosphere – Oxygen-Warmer –Space Shuttle & Station Orbitals

Mesosphere –

Stratosphere –Jet Aircraft &Weather balloons fly

Troposphere – Water vapour & Dust Particles – Warmer upward

Explanation:

Thermosphere: The thermosphere is a layer of Earth’s atmosphere below the exosphere and above the mesosphere.It extends about 90 km to between 500 and 1000 Km The temperature is 200◦C. very hot in the day than night.

Mesosphere:It lies above the stratosphere and extend from 50 Km to 85 Km Jets and balloons do go high.

Stratosphere: It is second layer of the earth’s atmosphere starts above the Troposphere and ends 50 km above the ground.Ozone is abundant here which absorbs the UV radiation from the sun.

Troposphere:It is layer closes to the earth’s surface.It extends 7 -20km above the ground contains half of the atmosphere.All of the water Vapour and dust are in this layer.

The flow of electrons down the respiratory chain allows the active transport of _________ to the outside of the cytoplasmic memb

harina [27]

Answer:hydrogen ions

Explanation:in the mitochondria,electrons pass down a chain of carrier molecules from a higher energy level to a lower energy level.energy is released from this process and this energy is used to pump hydrogen ions into the inter membrane space of the mitochondria.this causes a gradient which is harnessed for the formation of ATP from ADP and an inorganic phosphate.

In plants tall (T) is dominant to short (t) and round seed is dominant to wrinkled seeds (r). If a parent is short and wrinkled

Nuetrik [128]

Answer:

Parent cross= ttrr (short, wrinkled) × TtRr (hybrid)

POSSIBLE GAMETES BY EACH PARENT:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

Explanation:

This question involves two genes in a certain plant. One gene is coding for height while the other is coding for seed shape. The alleles for tallness (T) and round seeds (R) is dominant over the alleles for shortness (t) and wrinkled seeds (r).

According to this question, a parent that is short and wrinkled (ttrr) is crossed with another parent that is hybrid (TtRr) for both traits. This means that the parent cross is as follows: ttrr × TtRr

The possible combination of gametes that will be produced by each parent is as follows:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

See attached image for the punnet square using these gametes.
