Answer:
1) Bees swarm to find shelter and increase their chances of survival.
Explanation:
Options are
1) Bees swarm to find shelter and increase their chances of survival.
2) The worker bees have an increase of survival due to their ability to find a mate.
Bees swarm to find new shelter because the population is high in the hive so they find a new place for themselves. For finding new shelter, the scout bees go to different places for finding a suitable place for making hive. These splitting of a single population of bees into two that increase their chances of survival in the environment. They choose their shelter in that area where plenty of flowers are present and safe from predators.
Answer:
Interphase is the longer phase where cell prepares itself for mitosis.
Interphase is the time when a cells metabolic activity is very high as it performs various functions.It is divided into G1,S PAHSE and G2.
G1 phase
synthesis of proteins
synthesis of organelles
growth in size
Sphase
duplication of chromosomes
growth in size
G2 phase
more growth
synthesis of proteins essential for mitosis
Explanation:
Answer:
Phenotypic ratio - 3 Freckes : 1 No freckles
Explanation:
This question represents a monohybrid cross i.e. involving a single gene coding for possession or not of freckles. The allele for possession of freckles (F) is dominant over the allele for no freckles (f).
In a cross between two HETEROZYGOUS parents i.e. Ff × Ff, each parent will produce gametes with alleles F and f respectively. Using a punnet square (see attached image), four possible offsprings will be produced with genotypes: FF, Ff, Ff and ff.
Based on this genotypes, the phenotypic ratio of the offsprings will be 3:1 where 3 offsprings will possess freckles and 1 will have no freckles.
