Answer:
bronze
Explanation:
Bronze, an alloy formed by adding tin to copper, fuses at a lower temperature than copper and is thus better suited for casting; it also is harder and less malleable.
1. an atom
2. compound
3. both
4. atom
Answer:
The correct answer would be "Each parent is either M or MN".
Co-dominance is the condition in which both the alleles express themselves completely when present in the heterozygous condition.
The blood group of the offspring can be of M type in two conditions:
1. When both the parents are of M blood group
2. When both the parents are heterozygous for the blood group that is, they both are MN.
Answer:
There are 64 fish, 8 ducks and 4 turtles.
Explanation:
From the question, there can be from 2 to 99 fish in the pond. However, there cannot be fractions in the number of fish, ducks or turtles. Hence, the number of fish must have both of a perfect square and perfect cube. The perfect squares from 2 to 99 are 4, 9, 16, 25, 36, 49, 64 and 81. The perfect cubes from 2 to 99 are 8, 27 and 64. Since only 64 fits both criteria, the number of fish is 64. The number of ducks is the square root of number of fish, which is the square root of 64. The square root of 64 can be either positive 8 or negative 8. However, there cannot be negative numbers, so there are 8 ducks in total. The number of turtles is the cube root of the number of fish, which is the cube root of 64 and it is 4.
Answer:
Antibodies
Explanation:
Bordetella pertussis is an obligate human pathogen and is the etiological agent of whooping cough. It is known to be an opportunistic organism.
The pathogenic mechanism of Bordetella pertussis is also known as virulence factor. These virulence factors are known to include adhesins such as filamentous haemagglutinin, fimbriae and pertactin, which allow B. pertussis to bind to ciliated epithelial cells in the upper respiratory tract.
It is known to be the agent of whooping cough, a highly contagious respiratory disease, dramatic for infants and also for elderly and pregnant women.
In this case, the antibodies will be the response that is uniquely directed against the organism. It is said earlier that this organism is an opportunistic one, this means that it causes infection when the immunity is down. So, when the immunity is empowered , it will definitely fight against the organism
