Answer:
Child-directed speech is the term that describes the way that we typically talk to babies to get their attention
Explanation:
<u>Correct Answer</u>
Child-directed speech:- It is the speech that we follow when we talk with babies. It is also called caretaker speech, infant-directed speech, child-directed speech, child-directed language, caregiver register etc
<u>Incorrect Answers</u>
Mean length of utterance:-Mean length of utterance is a measure of Language productivity in children. It is generally calculated by collecting 100 words spoken by a child and dividing the number of morphemes (Meaningful concept) by the number of words. A higher mean length utterance is considered to indicate a higher level of language speaking ability.
Babbling:- Babbling is a phase in infant development and a state in language procurement during which a baby appears, to be explored by uttering different articulate sounds, however, it doesn't create any recognizable words.
Holophrase:- Holophrase is the pre-language use of a single word to express a complex idea without any grammatical intent.

Explanation:
Answer:
C is Snotase, because it works best in neutral environments (hence the pH of 7)
A is Flotase because it works best in acidic environments (low pH)
B is Zoomase because it works in acidic environments (low pH)
D is Floxase because it works in basic environments (pH above 7)
Note:
For pH, 7 is considered neutral. Anything below that is acidic and anything above that is basic.
Complete question:
1). Determine the character states for the following six characters that are present in species OG, 5, 7, 15, 17, 18. Assign the character state found in the outgroup (OG) as a 0 and the alternative derived state a 1; use only two states per character. Example, stem width: 0 = thin, / = thick 1 <em>(Characters and plant species image in the attached files)</em>
2). Score each taxon using the 0 and 1 notation about and add to this matrix <em>(Matrix in the attached files)</em>
4). Reconstruct the phylogeny that most simply and accurately accounts for the distribution of synapomorphies among ingroup species. Given matrices as small and simple as the above example, one can build the tree from the bottom up in a series of sketches, adding clades or branches representing groups with the fewest synapomorphies near the base of the tree and those with the most at the tips. Using the unlabeled phylogeny as a starting point, draw the stepwise construction of a fully resolved phylogeny to account for all of the synapomorphies and include the synapomorphies that identify each clade (the first one, character 2, is included to get you started; this is shared by all members of the ingroup) (<em>Tree in the attached files)</em>
Answer:
- Stem width: Thick-1 // Thin-0
- Leaf edge (shape): Pointed-1 // Blunt-0
- Flower base (shape): Narrow-0 // Wide-1
- Flower orientation: Downward (Pendant)-1 // Upward (Vertical)-0
- Petal color: Purple-1 // Yellow-0
- Fruit shape (inset on card, on left): Round-0 // Elongated-1
- Complete Matrix in the attached files
- Order in the phylogeny reconstruction: OG --> 7 --> 5 --> 15 --> 17 and 18 (tree + evolutive changes in the attached files)
Explanation:
<em>NOTE: You will find the complete activity in the attached files. </em>
- The principle of maximum parsimony or maximum simplicity states that among all possible trees within a group of species, the most probable is the one that requires us to postulate the least number of evolutionary changes. So, to reconstruct a phylogeny we need to choose the tree that requires the less number of changes.
- To determine the character states for all the six characters, we assigned the number cero to all the characters expressed in the out-group. Thin steam, blunt leaf, narrow flower base, upward flower orientation, yellow petals, and rounded-seeds are all cero states. The other characters are 1.
- The above information of character state was used to fill in the matrix, specifying which character state belongs to each species according to their traits.
- The matrix was useful to reconstruct the phylogeny, to identify the autapomorphic trait, and to visualize all the clades.
