Suppose we found a solar system with the property described below. In light of what you have learned about the formation of our

solar system, decide whether the discovery should be considered reasonable or surprising. (a): A solar system has 15 planets that all orbit the star in approximately the same plane. The two planets closest to the star are terrestrial and the rest are gas planets?

Answer:

Surprising

Explanation:

This is surprising because the total number of planets in our solar system are nine which revolve around a central star i.e sun in different orbital paths.  

Also, out of 9 nearly four planets i.e Mercury, Earth, Venus and Mars are terrestrial i.e having some land forms. Out of remaining 5 non terrestrial planets nearly four planets are gas planets (Jupiter, Uranus, Neptune and Saturn) and these planets are distantly positioned from the central star

Hence, the given discovery is surprising

In rabbits, short hair(S) is dominant over long hair(s). What genotype and phenotype ratios are expected from a cross between tw
SOVA2 [1]

Answer:

Genotype                  Phenotype                      

SS                 1/4          Short hair         3/4

Ss                 2/4         Short hair          3/4

ss                  1/4          Long hair          1/4

Explanation:

Both are heterozygous for the trait so we can expect that the cross would be:

Ss x Ss

    S     s

S  SS   Ss

s   Ss   ss

So the resulting off-spring would have the following genotype and phenotype:

1 out of 4 will have a genotype of SS.

2 out of 4 or half will have a genotype of Ss.

1 out of 4 will have a genotype of ss.

But because short hair is dominant the phenotype ratios would differ because Ss and SS would express short hair, so we add up their ration:

Short hair: 1/4 + 2/4 = 3/4

Long hair:  1/4

So in summary:

Genotype                  Phenotype                      

SS                 1/4          Short hair         3/4

Ss                 2/4         Short hair        

ss                  1/4          Long hair          1/4

the diagram shows the movement of water through a plant which two terms or phrases describe the process shown
azamat

Answer:

B. Open Stomata

C. Transpiration

Explanation:

Even though plants take up a lot of water from their roots, they lose about 95% of it to the atmosphere in the process known as Transpiration.

Transpiration is done for several reasons: it cools the plant down, it enables plants to access the nutrients in the water as the water moves along the plant and it enables gaseous exchange.

The gaseous exchange happens because carbon dioxide comes in from the same holes on the leaf that the water leaves through to the atmosphere, the open stomata.

What two characteristics do fungi lack that forced them to become decomposers?? Please help :) **25 points**
Tamiku [17]
Fungi lacks the ability to produce their own food because they do not have chloroplast which is needed to obtain energy from the sun and convert it into food. Also fungi lack ability to fix nitrogen which has to be incorporated into their food. They also can not fix carbon and utilize it to produce food. Because of these they have to depend on dead organic matters for food.
