Answer:

Gene pairs segregate randomly and independently of each other.

Explanation:

Genes are the basic units of hereditary and are located on chromosomes. According to Gregor Mendel's law of independent assortment  which states that the alleles of two (or more) different genes are sorted into gametes independently of one another. This means that the allele a gamete receives for one gene does not influence the allele the same gamete receives for another gene.

For example, in a the pea plants used by Mendel in his studies, the genes for seed shape and flower color were inherited independent of each other by the offspring of the parent pea plants. Therefore, Mendel concluded that the inheritance of each trait was independent of the other.

Answer:

The stratosphere

contains the ozone layer ,

is used by airplanes,

has strong, steady winds , and

increases in temperature as altitude increases .

Explanation:

The stratosphere is the atmospheric layer between 10 km and 50 km above the Earth's surface.

It includes the ozone layer, which is at an altitude of about 20 km.

It has strong, steady winds that can reach as high as 220 km/h.

Passenger aircraft generally fly in the lower levels of the stratosphere, at altitudes of about 10 km to 12 km.

Temperatures increase with altitude, from -50 °C at 10 km to -3 °C at 50 km.

A is wrong. The mesosphere (altitude 50 km to 85 km) is the coldest of the atmospheric layers, with temperatures as low as -90 °C at 85 km.

Assuming a cell has just completed DNA synthesis, place these stages/steps in the cell cycle in the correct order of occurance b
shusha [124]

Answer:

The division of eukaryotic cell is done through various phase known as cell cycle.

Explanation:

The two basic phases of cell cycle is Interphase and Mitosis, that can be further divided into:

1) G2 Phase; G2 checkpoint ( Interphase stage)

2) Prometaphase (Mitotic Phase)

3) Anaphase  (Mitotic Phase)

4) Telophase  (Mitotic Phase)

5) cytokinesis (Mitotic Phase)

6) G1 Phase; G1 checkpoint ( Interphase stage)

After G1 phase there would be again S phase in which DNA replication occur.

9. a) How does hydrogen bonding help the transport of water in plants?
grigory [225]

Answer:

Water has a high Cohesion because of Hydrogen bonding. This is important as transport of water in the Xylem in plants relies on water being pulled up. Cohesion also gives the water a high surface tension, allowing small organisms, such as Pond Skaters, to walk along it.

Explanation:

Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

Plants obtain the hydrogen they need from water molecules. Don't try to feed your plant hydrogen gas -- your plant wouldn't know what to do with it if you did. As long as they have water, plants can readily obtain all the hydrogen they need. :)
