Are basal taxon more likely to have derived or ancestoral characteristics? Why?
Cladograms show the evolutive relationship between different taxa, and the ancestral and derived characters in the order in which they emerged. Basal taxons are more likely to have ancestral characteristics.
What is a cladogram?A Cladogram is a graph drown as a tree, which is based on cladistic analysis. It represents the common ancestral relationships and the emergence of different characters among the involved groups.
This tree-type graph represents the relationship between the involved taxa according to a derived character and follows the maximum parsimony criterium.
A derived character is any trait that a group passes to its descendants. Through evolution, the characters change, and new changes are added.
When referring to a derived character, we mean that all the subsequent species in the cladogram carry the trait.
A cladogram provides an image of how new species keep characters that were inherited from older species.
Cladograms show the position of the recent groups concerning the most ancestral ones and where, through history, the derived characters emerged.
Basal taxons exhibit ancetral characteristics that emerged a long time ago.The most recent groups exhibit derived characters that emerged later in history.
Derived characters do not appear in ancestral groups.
The basal taxons are more likely to have ancestral characteristics, while the most recent taxons are expected to exhibit the derived ones.

What is the phenotypic ratio of the offspring when a man who has type A blood, and whose mother had type O blood, marries a woman who has type AB blood?
2 type A : 1 type AB : 1 type B
3 type A: 1 type B
1 type A : 1 type O
1AA :1AB : 1AO : 1BO
Answer:
The correct answer is - 2 type A : 1 type AB : 1 type B
Explanation:
The pattern of the inheritance in the ABO blood group system is the example of the multiple alleles and codominance. There are three alleles in this sytem that determines what blood group would be in an indvidual that are; IA, IB, and IO. The allele IO is a recessive allele to both IA, and IB alleles whereas IA and IB are show codominance when present in heterzygous condition.
Genotype of a person with “A” blood group can be IA IO or IA IA but as it is given that the mother of the male with A bglood group is O blood group which means there must be a IO allele would be present in the male too so the genotype would be IAIO.
The genotype of AB blood group mother would be IAIB as shows codominance. so the cross between these woulde be as follows:
IA IO x IA IB
Gametes :
IA IO , and IA IB
IA IO
IA IAIA IAIO
IB IAIB IBIO
phenotypic ratio = 2 A group : 1 AB group : 1 B group

For what length of time was the IT Support department able to close down each weekend during Richard's first month?
Nixon's concerns turned out to be valid. The unemployment rate reached a politically harmful 6 percent by the end of 1970.
In that year, Nixon named Arthur Burns as the head of the Federal Reserve. Burns rapidly established his independence by issuing Nixon a challenge: if Nixon failed to maintain federal spending under $200 billion, Burns would continue to keep the money supply constrained in an effort to combat inflation. Nixon complied with Burns' requests. He put off government employees' salary raises by six months in order to conserve money. One outcome was a nationwide postal employees' strike. Nixon employed the U.S. Army to keep the postal service operating, but in the end, he carved into postal workers' salary demands, erasing some of Burns' budget-balancing requirements.

Autopsy conducted on an individual who had died of pneumonia revealed bluish-green pus filling the lung. The causative agent of pneumonia was most likely to be
Proteus vulgaris
Escherichia coli
Salmonella typhi
Pseudomonas aeruginosa
Staphylococcus aureus
Answer:
The agent causing the pneumonia, where bluish-green pus was found, is most likely Pseudomonas aeruginosa.
Explanation:
Pseudomona aeuriginosa is a gram-negative bacteria that is one of the main causes of hospital-acquired infections, including pneumonias in mechanically ventilated patients.
One of the characteristics of P. aeuriginosa is the formation of a bluish-green pus, since it has the capacity to form cyanide-based blue pigment upon contact with the organic tissues it infects. This is the reason why previously P. aeruginosa was called a pyocyanic bacillus.
The other options are not correct because the only bacterium that produces blue-green pus is P. aeruginosa.

Answer:
100% red eyes because there is 50% AA and 50% Aa.
Explanation:
To find the expected ratio of male and female phenotypes if they were bred together, you need to make a punnett square/table.
Female: A a
"A" is white eyes, which is RARE. "a" is red eyes, which is COMMON.
Male: A A
"A" is red eyes, which is COMMON.
Multiply Aa x AA by a punnett square.
GUIDE:
1. AA is common and does not carry the recessive gene of being white-eyed. 2. aa is rare and carries the recessive gene of being white-eyed.
3. Aa is common as being red-eyed since being red-eyed is dominant, but carries the recessive gene of being white-eyed.
