Biology
1 answer:
Leni [432]2 years ago
6 0

Answer:

There are many reasons why manned space probes to Saturn are simply  unachievable. Getting to space is incredibly hard. The force of gravity is very hard to escape. If you wanted to, you would have to invest trillions upon trillions of dollars to create a space shuttle that may or may not explode. Second, we simply don’t have the technology to make it that far with a manned probe. Saturn is more than a billion miles away. It would take more than several years to go that far. To keep astronauts alive, entertained, and sustained is also a big challenge. In conclusion these are some reasons why a manned space probe to Saturn is unachieveable.

Explanation:

U’d better give me that brainly.

What fraction of offspring of the cross AaBb × AaBb would be homozygous for both the dominant alleles, assuming that they are on
Veseljchak [2.6K]

Answer:

A. 1/16

Explanation:

If we break the dihybrid cross of AaBb X AaBb into individual monohybrid crosses:

Aa X Aa :

     A    a

A  AA Aa

a  Aa   aa

1/4 of the progeny will be homozygous for dominant allele (AA)

Similarly, in cross Bb X Bb 1/4 of the progeny will be homozygous for dominant allele (BB)

Hence, in cross AaBb X AaBb:

1/4 * 1/4 = 1/16 will be homozygous for both the dominant alleles.

How are predation and competition essential for maintaining a thriving ecosystem?
Elis [28]

Answer:

<u>Both of these are necessary to maintain overpopulation of any species in an ecosystem.</u>

Explanation:

  • Predation is an act in which one organism eats another organism present in the ecosystem.

  • The one eaten is called prey, while the dominant organism is called Predator.

  • Since an ecosystem is made up of many organisms along with the natural resources present in it.

  • This gives rise to different species competing against one another.

  • If one of these species is at a certain advantage, their population will rise uncontrollably hence to prevent this a predator plays a major role.

  • On the other hand, competition is a term which describes the harm caused to two different organisms.

  • This is due to the limited number of natural resources like food, water or shelter etc.

  • Organisms who are less likely to adapt according to the changing environment ultimately die.

  • For example, Plant roots over time lessen the amount of nitrogen present in the soil, causing the neighboring plant to die.
