The question is incomplete, here's the complete question;
Black truffles are a unique type of fungi that are highly prized by chefs and food enthusiasts throughout the world. Which of these characteristics is seen in truffles but not in common mushrooms?
a. lack a reproductive phase
b. contains hyphae
c. has spores contained in ascus
d. has spores contained in basidia
Answer is C. Truffles has spores contained in the ascus.
Explanation:
Fungi like yeasts, molds and mushrooms are eukaryotic organisms which acts as main decomposers in the environment. Black truffles are aromatic edible fungi which belong to the ascomycota phylum. They are expensive and normally seen in the southern Europe. The main feature of the ascomycota is the ascus, a sexual spore bearing cell containing spores called ascospores. Black truffles are round shaped with black-brown skin and has small pyramidal cusps. It contains tightly interwoven hyphae (long filament like structure) and numerous asci (spore bearing cells). Each ascus contains some spores called ascopores, which is specific to fungi classified as ascomycetes. Mushrooms belong to the basidiomycota phylum. They are also composed of hyphae and reproduce sexually via the formation of specialized cells called basidia which have spores called basidiospores.
Asexual:
One parent
Identical offspring
Less developed organism
Faster time period to produce
Sexual
Two parents
Unique offspring (genetic variation)
More complex organism
Slower time period to produce
Answer:
In this context, rice, rubber, timber, kenaf, tapioca, sugar, copra, cattle, and fish are as much natural resources as tin, oil, bauxite, coal, and iron ore. The chapter presents broader connotation. Southeast Asia is a traditional producer and exporter of raw materials and of natural resources.
Explanation
:)
Given
E dominant allele for wet
e recessive allele for dry
that means
for phenotype wet, the possible genotypes are EE, or Ee, and
for phenotype dry, the only possible genotype is ee.
Therefore we also know that the child who has dry earwax has genotype ee.
Since the child inherits one allele from each parent, therefore each parent must have a recessive allele "e".
If both parents have phenotype wet earwax, they both must be heterozygous for wet/dry earwax, namely Ee.
