Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the morphological species (morphospecies) concept. Match each characteristic with the species concept(s) to which it applies. Species:
1. biological
2. morphological
3. phylogenetic
4. morphological and phylogenetic
5. biological, morphological and phylogenetic
Characteristics:
1) accommodates asexual reproduction
2) not applicable for extinct species
3) relies on similarities of structures
4) used by scientists in classification
5) species acceptance criteria can be subjective
6) based on evolutionary history

Answers

Answer 1
Answer:

Answer:

Biological species concept defines species as individual in a population that can interbreed and produce viable offsprings. Therefore Biological species concept is not applicable for extinct species

Morphological means in relation to structure therefore, this concept relies on similarity of structure to classify species.

Phylogenetic refers to members having the same ancestor. It classifies species according to common ancestry. Hence it will be based on evolutionary history.

Morphological and phylogenetic- Will accommodate asexual reproduction and species acceptance criteria can be subjective.  

Biological, morphological and phylogenetic-Together they are used by scientists in classification
Answer 2
Answer:

Final answer:

In the context of biological species, it does not support asexual reproduction and is not for extinct species. Morphological species, rely on structure similarities, are used for classification, and have subjective species acceptance. Phylogenetic species are based on evolutionary history, supports asexual reproduction, and has subjective species acceptance criteria.

Explanation:

The three significant concepts of species include the Biological species concept, Phylogenetic species concept, and Morphological species concept.

1) Biological species - This concept does not accommodate asexual reproduction (2) and is not applicable to extinct species (2).

2) Morphological species (or morphospecies) - This concept relies on similarities of structures (3), is used by scientists in classification (4) and the species acceptance criteria can be subjective (5).

3) Phylogenetic species - This concept is based on evolutionary history (6), can accommodate asexual reproduction (1) and the species acceptance criteria can be subjective (5).

The morphological and phylogenetic concepts are used by scientists in classification (4) and their species acceptance criteria can be subjective (5).

All three concepts - biological, morphological, and phylogenetic - are all considered in the broader understanding and definition of species.

Tail length in mammals is a heritable trait. A pig with a 6 cm tail was mated to a pig with a 30 cm tail. All F1 offspring had a tail of length 18 cm. An F2 generation was made by crossing F1 individuals. This resulted in many piglets whose tails ranged in 4-cm intervals from 6 to 30 cm (6, 10, 14, 18, 22, 26, 30). The majority of pigs had 18 cm tails, 1/64 had 6 cm tails, and 1/64 had 30 cm tails.These results are consistent with what genetic model?(a) Two genes, each with two alleles that show dominance(b) Two genes, each with two alleles that act additively(c) Three genes, each with two alleles that show dominance(d) Three genes, each with two alleles that act additivelyAn F2 piglet with an 18 cm tail is heterozygous at each of the tail-length loci, and is mated to an F2 piglet with a 6 cm tail.

What is this called?

Answers

Answer:

phototropism.
Even mature plants bend toward the strongest light. They do this by elongating the cells of the stem on the side that is farthest from the light. This type of light-oriented growth is called phototropism.

The answer is phototropism

toss all 4 coins together 50 times and keep a tally sheet while doing so. How many tally's for each genotype did you get?

Answers

Here is my answer. When I toss 4 coins together 50 times and kept a tally sheet while doing so, here are the number of tally's I got for each genotype:
BB=12.5
Bb=25
Bb=12.5
In this case, this gives me the probability of the following:
BB=25%
Bb=50%
bb=25%

The pericytes used in these experiments were probably in which phase of the cell cycle

Answers

Answer: Interphase

The pericytes are in the interphase of the cell cycle. This is the phase of the cell cyclebetween each cell division and is the phase in which the cell obtains nutrients,grows, reads its DNA, and conducts other normal cell functions including thearrest of the growth of the pericytes that were treated so that they would notdivide but continue to function normally.

The reason that there are Okazaki fragments during DNA replication is ultimately because:A) Some parts of the chromosome are made of RNA and different polymerases have to be used
B) Polymerases can only synthesize in the 5' to 3' direction
C) There are only enough dNTP's to support quick replication on one strand, so the other strand lags behind it
D) It is necessary to "slow down" one of the strands so that replication does not occur before cells have a chance to grow

Answers

Answer:

B) Polymerases can only synthesize in the 5' to 3' direction

Explanation:

The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.

The ____________ is sometimes called the "funny bone" because of the tingling sensation (pain) one feels if the ____________ is bumped. The ____________ passes underneath this bony landmark.

Answers

Answer:

Ulnar nerve is also called funny bone and feels tingling sensation if humerus is bumbed. Medial epicondyle passes underneath this bony structure.

Explanation:

The funny bone isn't actually a bone, its actually a nerve that touches your humerus.It is the ulnar nerve, which travels down the arm posteriorly and eventually reaches the "cubital tunnel" and at this location (between the trochlea and medial epicondyle of humerus),  ulnar nerve is called funny bone.

The nerve is relatively unprotected at this place.

A blow here may produce a tingling or a numbing sensation throughout the forearm and hand.

Hence, Ulnar nerve is also called funny bone and feels tingling sensation if humerus is bumbed. Medial epicondyle passes underneath this bony structure.

Final answer:

The ulnar nerve, sometimes called the "funny bone," causes tingling sensation when the elbow is bumped.

Explanation:

The ulnar nerve is sometimes called the "funny bone" because of the tingling sensation (pain) one feels if the elbow is bumped. The ulnar nerve passes underneath this bony landmark.
