The answer is B because if you recross them you get the same answer Rr and rr so the correct answer is B
<h2>Answer</h2><h3>A. Kingdom, phylum, class, order</h3><h2>Explanation:</h2>
The taxonomic groups are basically used in the scientific classification from most general to most specific. There are seven main taxonomic levels such as kingdom, phylum or division, class, order, family, genus, species. The most specific classification is genus and species. The broadest classifications are by domain and kingdom.
Answer:
1/64
Explanation:
<em>The probability of the offspring being homozygous dominant for the three alleles is 1/64.</em>
Since the three characters assort independently, the probability of the offspring being homozygous dominant for all the three traits is an independent event.
For independent events, the probability of all the events happening together is the multiplication of individual event's probability.
For a cross involving two heterozygotes, taking tall/dwarf for example:
Tt x Tt = TT, 2Tt, tt
The probability of obtaining a homozygous dominant genotype is 1/4.
Hence, the probability of the offspring being homozygous dominant for the three alleles will be:
1/4 x 1/4 x 1/4 = 1/64
The mineral salts concentration in the roots increased when the oxygen concentration in the solution increases by 10 per-cent because the roots uptake minerals and salts by active transport which requires ATP and Oxygen is required by cellular respiration in root cells.
Explanation:
The root hair cells have membrane protein on them which assist in active transport of the minerals and ions to the root cells. When the oxygen concentration is increased by 10% the cellular respiration in the root cells occur faster, producing ATP and aiding in faster active transport and hence increasing the mineral and ion concentration in roots of the plant.
Answer:
Get to know the four main types of pollution present in the environment, and then look at a variety of real-world examples as you try to guess what type of pollution is represented by each situation. All of the real-world situations can be viewed every day in different parts of the world.
