MakcuM [25]4 years ago
6 0

The scientists rely on the following cues to hypothesise and test for the presence of life on various extraterrestrial bodies:

1. Presence of water

2. Presence of hydrocarbons

3. Presence of carbon

4. Presence of salt pans  

The presence of hydrocarbons may indicate that there's anaerobic life thriving beneath the surface of the meteorite. The presence of traces of carbon may indicate that there was life once thriving on its surface ( which however is not possible in case of a meteorite because of its size). The absence of any of the above listed items will indicate that the surface of the meteorite is devoid of any life.

An animal with long limbs, a long tail, and hand-like paws that can grab things would be best suited for which environment?
frosja888 [35]
<span>An animal with these such features would be well suited to live in environment like the rain forest. Its long limbs and tail would allow it to swing from tree to tree, and also reach up into the trees to gather food. The hand-like paws would make climbing easier, and allow the animals to grab food from higher places.</span>

What is a ecosystem? write 2 to 5 sentences to explain it​
Nonamiya [84]

Ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.

For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.


An ecosystem consists of a community of organisms together with their physical environment.
Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes.
In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.
Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, or disruptive events.

Assume that in cattle a spotted coat is dominant to an even coat, short horns are dominant to long horns, and the traits for coa
kow [346]

Answer:

C. 1/4

Explanation:

Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=

9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.

Therefore, the proportion of the progeny with long horns = 4/16= 1/4
