Spores are the reproductive unit produced as a result of sexual reproduction and asexual reproduction in both lower and higher plants.

The spores are formed by the process of sporogenesis which forms four spores from a diploid structure their meiosis which reduces the genetic material to half and maintain the haploid ploidy number.

Why would scientists analyze another specimen from the same species
Mashutka [201]

Among the most frequently used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known standard sequences are estimated using phylogenetic trees.

<h3>What is a phylogenetic tree?</h3>

Among the most commonly used species identification methods are: The evolutionary relationships between the unknown sequence and a set of known reference sequences are estimated using phylogenetic trees.

A phylogenetic tree is a diagram that depicts the evolutionary relationships between organisms or groups of organisms.

Scientists consider phylogenetic trees to be evolutionary hypotheses because the proposed relationships cannot be confirmed in the past.

Thus, every individual of same species are related to each other, so  scientists can analyze another specimen from the same species.

Select the statements that best explain Makali's GALT activity levels? Makali may have a mutation in the gene that encodes galac
adelina 88 [10]

Answer:

Makali may produce only small amounts of a non-mutated (wild-type) GALT enzyme.

Makali may have normal amounts of GALT, but the enzyme may be mutated.

Explanation:

Makali is lactose intolerant because of his ancestry. Because of this he is not able to digest any lactose which indirectly protected him from galactosemia. Thus he must avoid consuming galactose. He has a low GALT or galactose 1‑phosphate uridylyltransferase activity. He has a normal amount of GALT and may produce only small amounts.
