Answer:
tentatively group it with birds and speculate that the trait shared only with bats is a derived rather than an ancestral trait with bats.
Explanation:
The scientist after his observation should tentatively classify this organism with birds and the the second end of calculating the other morphological traits which makes it possess the likely bat traits to be ancestral.
According to scientists, most widely used modern systematic practice
depends upon the assumption that a change from character in one species
to character occurs once and once only in the evolutionary process and that this process is irreversible so that it never returns.
In this scheme, there are no independently derived parallel evolutionary changes,
nor convergences from a variety of states to a single one. Therefore, when two organisms share a
character state different from other species, it is because they are more closely related to each other through a recent common ancestor than they are to other species.
Also using the parsimony principle, a scheme of common ancestry for all the species is derived that uses all the characters that have been observed.
Answer:
After the flood the total number of beetles = number of beetles per hectare × 115 hectares = 8,855 beetles.
The carrying capacity is 14,600 beetles.
Explanation:
1. flask-shaped gland unbranched ducts=SIMPLE ALVEOLAR GLAND
2. slender, straight gland unbranched ducts = SIMPLE TUBULAR GLAND
3. combination of gland shapes = TUBULAR ALVEOLAR
4.branched ducts=COMPOUND GLAND (salivary glands)
All of them are the exocrine glands (their product is secreted on the epithelial surface).
Answer:
Explanation:
A raft is a flat-bottom structure made of planks or barrels that has the capacity to float on water. While an ecosystem is a community of living organisms (biotic) interacting with there non-living (abiotic) environment as an ecological unit.
A raft by design cannot withstand much load because of it's size or can only accommodate only one type of organism at a time but an ecosystem generally accommodates a community (different organisms), hence the carrying capacity of an ecosystem is way larger than that of a raft and indeed a raft can be part of an ecosystem at some point
The enzymes which aid in the digestion of proteins in the stomach is called pepsin. Pepsin needs an optimum pH of about 2 to be effective and that is why the hydrochloric acid is usually secreted in the stomach.
In the situation where an antacid is used and the acidity of the stomach is neutralized, then, the pepsin enzyme will not be able to perform its function because of altered pH and the protein content of the eaten food will not be digested leading to indigestion in the affected person.<span />
