I think the answer would be "A"
Answer:
It must belong to the Kingdom Fungi.
Explanation:
Fungi are the organisms that have long thread-like structures called hypha in their body. Many hyphae together form a mass called mycelium. Fungi are eukaryotes and have a well-defined nucleus in their cells. They also have cell walls that are made up of chitin. Fungi are mostly multicellular. However, yeast is the fungi that have a single cell in their body. Fungi are heterotrophs and derive their nutrition by parasitic or saprophytic mode of nutrition. Therefore, the given description tells that the microbe should be a fungus.
Answer:
1. They keep casts to preserve the real fossils.
2. Maybe someone would steal a fossil and sell it on the dark web?
3. They keep casts to keep the real fossils in prime condition, by that I mean like undamaged.
Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.
