It’s mass and speed. This is because the equation for Kinetic energy is KE=1/2mv^2
Allele that causes yellow eyes (Y) is
dominant over the allele that causes orange eyes (y)
Y = 85% = 0.85 and
y = 100% - 85% = 15% = 0.15
f(y) = square root of y = √y = √0.15 =
0.387
frequency of the allele that causes
orange eyes = 0.387
Once we know the value of y, Y + y = 1
Putting the value of y, we get
Y = 1 – 0.387
<span>Frequency of the dominant allele that
causes yellow eyes = 0.61</span>
Answer:
D) They can increase the reaction rate for a given reaction by a thousand-fold or more.
Explanation:
Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.
Answer:
Autotrophs are organisms that use light energy or energy stored in chemical compounds to make their own food.
1st order heterotrophs are organisms that eat only plants
2nd order heterotrophs are organisms that eat herbivores
3rd order heterotrophs: organisms that eat herbivores and other carnivores
Top group: carnivores
Explanation:
Producers are named as such because they produce their own food either by photosynthesis or chemosynthesis. These organisms are called autotrophs and include plants.
There are various levels of consumers. The first is first order heterotrophs, which feed on the producers. These are herbivores and include, for example, a deer feeding on grass.
The next is second order heterotrophs, which feed on the first order heterotrophs. E.g. an owl eating a mouse. These are carnivores
The next layer are also carnivores, third order heterotrophs which eat second order heterotrophs, for example a lion eating a zebra.
