Answer: They will each have 4 chromosomes.
Explanation:
They will each have the same number of chromosomes (4) as you cannot gain or lose chromosomes unless there is a genetic mutation that has occured.
Answer:
Decomposers
Explanation:
Decomposers eat decaying or dead organisms to produce the nutrients.
Answer:
The three genes in coupling are in repulsion.
Explanation:
Coupling happens when the dominant alleles and the recessive alleles are on the same homologous chromosome, while the repulsion happens when one chromosome has one dominant allele and one recessive allele and another homologous chromosome also has dominant and recessive alleles.
If the progeny has:
nb+ ls+ a/nb ls a ⇒ nb+ ls+ a
nb ls a+/nb ls a ⇒ nb ls a+
Where nb+ ls+ a is the dominant alleles and nb and nb+ is in middle.
ls+ nb+ are on the same chromosome (both dominant)
ls nb are on the same chromosome (both recessive)
ls nb, these two are in coupling with each other, but ls+ and a are on the chromosome and ls+ or nb+ are dominant, while nb+ and a are recessive on form a, thus, ls and nb, they are in repulsion with a.
Answer:
<h2>Secondary air pollutants are pollutants which form in the atmosphere.</h2>
Explanation:
Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight; NO2, which is formed as NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with water.
Answer:
Single stranded template to produce a double stranded product.
Explanation:
Polymerase chain reaction (PCR) is a technique in the laboratory that is used to make many copies (millions or billions) of a particular region of deoxyribonucleic acid (DNA).
The reaction utilizes primers which are short pieces of single stranded oligonucleotide templates to yield a double stranded DNA.
Two primers are used in each PCR reaction, and they are designed to identify the target region to amplified they bind to opposite strands of the template DNA at the edges of the region to be copied. The template DNA is copied and a complementary DNA is produced. The end product of the reactions a double stranded DNA that is produced from the template dna. The new DNA is the exact copy of the template dna.
