Answer:
This is because ladybugs are replaced by pesticides that are responsible for not only contaminating crops but also for releasing dangerous gases into the ozone layer. Therefore, the use of these insects in crops makes the air more pure or avoids contaminating it with life-threatening pesticides for many living organisms.
The microbial theory of disease or germ theory of infectious diseases is a scientific theory that proposes that microorganisms are the cause of a wide range of diseases. These tiny organisms, almost all too small to see with the naked eye, invade humans, animals, and other hosts. Its growth and reproduction within the carrier can cause disease. "Germ" or microbe can refer to a virus, bacteria, protist, fungus, or prion.
Explanation:
The theory was a scientific discovery made in the second half of the 19th century, demonstrated by Louis Pasteur and that replaced previous explanations for the disease, such as the miasmatic theory or the theory of humors. Although highly controversial when proposed, it is now central to modern medicine and clinical microbiology, leading to such important innovations as the development of the vaccine, antibiotic, sterilization, and hygiene as effective methods against the spread of contagious diseases.
To exhibit a recessive trait, an individual must have two recessive alleles responsible for the trait. One recessive allele is from a mother and another is from a father. However, if a person has one dominant and one recessive allele, it will not exhibit the recessive trait. This is because recessive allele will be masked by the dominant allele. So, parents must be heterozygous (one dominant and one recessive allele) and must give their recessive alleles to the offspring so that only offspring exhibit the recessive trait.
Answer:
They can mimic a natural hormone and lock onto a receptor within the cell. The disruptor may give a signal stronger than the natural hormone, or a signal that occurs at the "wrong" time.
Explanation:
Answer:
Al children would have a Tall head shape
Explanation:
Patrick is purebred for the dominant tall head shape so his genotype would be TT. Patti on the other hand is short headed, which is recessive, so the only possible genotype would be tt. If we put that in a Punnet, you can see the result:
TT x tt
T T
t Tt Tt
t Tt Tt
Since all the results are Tt, that means the tall head shape would be expressed because it is dominant and it will mask the recessive trait. So the answer would be:
All children would have a tall head shape.
