Answer:
the answer is A 100%
Explanation:
Answer:
(1)Substrate, (2)Product and (3) active enzymes.
Explanation:
Enzymes are bio catalysts that increases the rate of a biochemical reactions. The enzymes has the ability to work at specific temperature and pH conditions only.
The enzyme binds with the substrate in a biochemical reaction and decreases the activation energy of the reaction. After that the substrate is converted into the product and active enzyme leaves the reaction.
Thus, the correct answer is (1)Substrate, (2)Product and (3) active enzymes.
Answer:
Plant and animal life is limited in areas with little access to sunlight.
Explanation:
This is B on edge if you are taking APES :)
C. Acetic acid contains a significant amount of carbon, but a sodium hydroxide contains no carbon.
Organic compounds are based on carbon. They also, almost always, include hydrogen as well.
Correct on the Edge exam.
B.people use soil differently
C.animals use soil in different ways
D.some countries do not have legislation protecting soil
Answer: A. the composition is based on the parent rock in that location.
Soil is formed by the process of withering of rock. Withering is a process of break down of rock into small fragments and further into small particles which aggregate in the form of soil by the action of agents like water and wind. The type of rock in a particular region may not be found other regions of the world. Also, the soil composition varies depending upon the type of parent rock withered to form that soil. Therefore, soil vary throughout the world because the composition is based on the parent rock in that location.
......Photosynthesis
B. 20
C. 10
D. 0
E. 1/2
Answer: Option C
Out of the 20 resulting offspring of the test cross, 10 (50%) will be tall.
Explanation:
Let True-breeding tall plant be "TT"
Let short plant be tt
On crossing, all offspring will be "Tt"
Test cross involves the breeding of an individual with a phenotypically recessive individual. The test cross of offspring "Tt" against "tt" will then yield an equal ratio (1:1) of Tt to tt.
Thus, out of the 20 resulting offspring of the test cross, only 10 (50%) will be tall.
When a true-breeding tall pea plant is crossed with a short plant, all the F1 offspring will be heterozygous tall. Upon performing a test cross of a heterozygous F1 tall plant with a short plant, about half of the resulting offspring should be tall. Thus, out of 20 offspring, approximately 10 (Option C) should be tall.
In garden peas, the allele for tall plants (T) is dominant over the allele for short plants (t). A true-breeding tall plant has two copies of the dominant allele (TT), while a short plant has two recessive alleles (tt). When you perform a test cross between a heterozygous tall plant (Tt) and a short plant (tt), the results should theoretically yield a 1:1 ratio of tall to short offspring. Since the question states the tall plant is true-breeding and crossed with a short plant, all offspring from this initial cross would be heterozygous tall (Tt). Each of these offspring, when test crossed with a short (tt) plant, would produce tall and short offspring in a 1:1 ratio.
Therefore, out of 20 offspring from the test cross, approximately half should be tall and half should be short. So, the expected number of tall offspring would be about 10.
The correct answer to the question is option C- 10.
