In addition to Earth, which planet has evidence of water on the surface?
O Mars
O Mercury
O Neptune
O Saturn
answer:
mars
explanation:
this is why scientists expect to find life on mars or even for humans to live thereAnswer:
Mars!
Explanation:
That's the reason why scientists would most likely to find sources of life on mars. Or maybe there's enough water for humans to live there.
In order to determine the expected average offspring length, what do you multiply with your heritability
Complete question:
In a population of toads, the average body length is 30mm. Body length is variable and the narrow sense heritability for body length is 0.1 for this population. You cross a male of 20mm with a female of 22mm. In order to determine the expected average offspring length, what do you multiply with your heritability?
30mm 9mm 0.1 8mm -9mm -0,5Answer:
The correct option is -9mm
In order to know the expected average offspring length, OABL, we need to multiply the selection differential, SD ( -9mm) with narrow-sense heritability, h² (0.1).
Explanation:
Available data:
the average body length, ABL, is 30mmthe narrow-sense heritability, h², for body length is 0.1male of 20mmfemale of 22mmTo answer this question, we need to remember how can we calculate the selection differential and the heritability in the narrow sense.
We can get the selection differential, SD, by getting the difference between the mean value of a population length, ABL, and the mean value of the parents of the next generation, PABL. So, in this example the selection differential is:SD = (20mm + 22mm)/2 - 30mm
SD = 21 mm - 30mm
SD = - 9mm
The heritability in the narrow sense, h², for body length in the population ish² = body lengths of the offspring average/selection differential
But we already know the value of h². And we want to know the body length of the offspring. So we just need to clear the following equation.
OABL = ABDL + h² ( PABL - ABL)
where,
offspring average body lengths = OABLpopulation average body length = ABL = 30mmparents average body length = PABL = 22mmSelection diferential = SD = -9mmnarrow sense heritability = h² = 0.1OABL = ABDL + h² ( PABL - ABL)
OABL = ABDL + h² ( SD)
OABL = 30mm + 0.1 ( -9mm)
OABL = 30mm + (-0.9 mm)
OABL = 21 mm
In order to know the expected average offspring length, OABL, we need to multiply the selection differential, SD ( -9mm) with narrow-sense heritability, h² (0.1).

E. Coli is a bacterium that lives in the gut of humans. The human provides the ideal habitat for e coli reproduction and the e coli provides the extra vitamin K that we use.
Group of answer choices
Parasitism
Predation (Predator-Prey)
Mutualism
Commensalism
Answer:
The correct answer is - Mutualism.
Explanation:
E. coli and humans have a parasitic relationship as these organisms cause harm to the Humans while they reproduce themself, however, E. coli also have a mutualistic relationship with humans that are present in the gut of the human's digestive tracts.
These bacteria help in providing vitamin k and nutrients to humans that is essential for the clotting of blood and the human provides the ideal habitat for E. coli reproduction.

what is the breakdown of glucose, anabolic or catabolic reaction called
Answer:
The correct answer is - catabolic reaction.
Explanation:
The breakdown of glucose is the catabolic reaction as it releases the energy in the process which means the breakdown of large molecules into its components is known as a catabolic reaction.
Catabolic reactions are generally downhill reactions as they release energy and result in the formation of the ATPs in this process. Anabolic respiration is a reaction that involves assembling of a small compound to form a new large molecule.

In what type of situations would random sampling (last lab) be useful?
In some types of research the target population might be as broad as all humans, but in other types of research the target population might be a smaller group such as teenagers, pre-school children or people who misuse drugs.
It is more or less impossible to study every single person in a target population so psychologists select a sample or sub-group of the population that is likely to be representative of the target population we are interested in.
This is important because we want to generalize from the sample to target population. The more representative the sample, the more confident the researcher can be that the results can be generalized to the target population.
One of the problems that can occur when selecting a sample from a target population is sampling bias. Sampling bias refers to situations where the sample does not reflect the characteristics of the target population.

What determines the type of animals that live in a biome? *
1 Soil and Rocks
2 The plant life
3 Latitude and altitude
4 None of these
Answer:
Plant Life
Explanation:
Due to the fact that prey outnumbers predators in all biomes, plant life is critical. Most prey are herbivores and this would contribute to the essential need for plant life. When it comes to predators, who are almost all carnivores, they may not need the plant life for food, but instead for shelter, hiding, and raising offspring.

What are the limitations on natural selection?
Answer:
Limits to variation The most obvious limit to natural selection is that suitable variation may not be available. This may be because certain phenotypes cannot be built, being ruled out either by physical law or by the properties of biological materials.
