Answer:
100% or 1
Explanation:
This question involves a gene coding for fur color in bears. According to the question, black fur allele (B) is dominant over the brown fur allele (b). This means that a bear heterozygous for fur color (Bb) will be phenotypically black.
In this question, a black father bear (genotype BB) and a brown mother bear (genotype bb) were crossed, the baby bears will all have a genotype Bb (see punnet square in the attached image). Since all the offsprings of this cross have genotype Bb, this means that 100% will have black fur.
It is gotten from the atmosphere by respiration, burning of fossil fuel, decay, excretion and decomposition of organic matter, fossilization etc
Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
Answer:
Two proteins that are present inside the same cell perform different functions because both proteins have different amino acid composition.
Explanation:
Amino acid is the building blocks of protein. Different proteins perform different functions due to their composition. These proteins are formed by the instructions given to the ribosome of the cell.
Answer:
meiosis
Explanation:
meiosis is used to produce gametes for sexual reproduction
