Answer:
actin
Explanation:
B) intellectual disability
C) a mutation in his offspring
D) a change in his somatic cells
The germline mutation is heritable variation in the lineage of germ cells. Germ cells are cells that give rise to the gametes, so a mutation in germ cell will be seen in a sperm cell (man's gamete) but not in a body cell. If present in the sperm cell, after fertilization with an egg cell, the mutation will be present in formed zygote. So, man's offspring will have the mutation
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.

Hi
The answer is : They are complex chemical reactions
I hope that's help !
I hope my answer is one of the choices :)
Answer:
It is used by every living cell

The only process that does not generate energy is Photosynthesis. Photosynthesis does not release energy from glycolysis, whereas cellular respiration, fermentation, and glycolysis do.
The animal, human, and plant all get energy from cellular respiration, which is the oxidation of glucose. Glucose is synthesized by plants, which are producers through the photosynthesis process, and this glucose is synthesized by plants and animals use it for energy production.
The glycolysis process involves oxidation of the glucose to produce pyruvate, which is then fed into the electron transport chain to produce ATP. If the pyruvate does not receive enough oxygen, it enters the fermentation process to produce ATP, but only a small amount of ATP is produced. When the pyruvate gets enough oxygen, complete oxidation of the glucose takes place.
Hence, Photosynthesis, the final option, is the only process that does not generate energy from glucose but makes glucose.

The question is incomplete, the complete question might be the following.
Which process does NOT release energy from glucose?
a. glycolysis
b. fermentation
c. cellular respiration
d. photosynthesis
Answer:
Photosynthesis
Explanation: Hope it helps!!
b. gel electrophoresis.
c. an electrical current.
d. whole animal cloning.
The answer is A .
PCR stands for Polymerase Chain Reaction. It is a method to analyze a short sequence of DNA or RNA and is used to reproduce (amplify) selected sections of the nucleic acid. Untold numbers of copies can be made of the DNA in just a few hours.
PCR amplifies the regions of DNA that it targets and can therefore be used to analyze extremely small amounts of sample. This is often critical for forensic analysis, when only a trace amount of DNA is available as evidence.
B. cities
C. forests
D. industrial areas
Hedgerows have created new ecosystem within Britain's farms which are patchwork quilts.
Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By the decomposition of the dead plants and animals by action of microbes nutrients are released back in to the soil.
