n horses, the hair color gene has a dominant allele B (Black) and a recessive allele b (Chestnut). The gait gene has a dominant allele T (Trotter), and a recessive allele t (Pacer). If a Black Trotter is heterozygous for both traits, how many types of allele combinations for these 2 traits can be found in the gametes it produces
Stereoscopic vision, grasping hands and flat nails rather than claws seem to be good adaptations to living in trees. However, some scientists have hypothesized that these traits were more likely selected for catching small prey. Why?

This is an example of competitive exclusion. Over many generations, Gentoo penguins in another area adapt to feed on krill at greater depths than the Chinstrap penguins. This is an example of adaptive radiation.
Competitive exclusion is a principle in ecology that states that two species that occupy the same niche cannot coexist indefinitely. If one species is better adapted to the environment and has a competitive advantage over the other, it will outcompete the other species and drive it to extinction. This is what appears to have happened in the case of the Chinstrap and Gentoo penguins. These two species occupy the same area and have the same food source, which means that they are competing for the same resources. Over many generations, the Chinstrap penguins, which are better adapted to the environment, were able to outcompete the Gentoo penguins and drive them to local extinction. Adaptive radiation, on the other hand, is the evolution of a single species into multiple species that each occupy a different niche. In the case of the Gentoo penguins, it appears that they were able to adapt to feeding on krill at greater depths than the Chinstrap penguins. This allowed them to occupy a different niche and coexist with the Chinstrap penguins without competing for the same resources. Adaptive radiation can occur when a species colonizes a new area with a variety of available niches or when a species evolves to exploit a new resource. In both cases, the species is able to diversify and occupy a variety of niches, allowing it to coexist with other species that occupy different niches.

I. ActA binds to the Arp2/3 complex
II. E. Coli in which ActA is expressed moves in host cell cytosol
III. Listeria lacking the ActA gene fail to move inside the host cell cytosol.
IV. ActA has 3 transmembrane domains
V. Arp2/3, when activated, nucleates a branched actin network
A. I and II
B. II and III
C. I and III
D. III and IV
E. I and V
Answers
Answer:
The correct answer is option B. "II and III".
Explanation:
In order to prove that ActA protein of Listeria is necessary and sufficient for bacterial movement within its host cell a series of results in transformed Listeria and transformed E. Coli must be obtained. First, if Listeria lacking the ActA gene fail to move inside the host cell cytosol it will prove that ActA is necessary for bacterial movement. Second, a transformed E. Coli that expresses ActA should be able to move in host cell cytosol. Wild type E. Coli does not expresses ActA, if ActA alone makes E. Coli able to move in host cell cytosol it will prove that ActA is sufficient for bacterial movement.

The step-by-step plan for dealing with broken glassware on the floor or lab table has been stated below:
1 tell the person in charge or the teacher
2 make sure u did not get cut
3 get the large pieces and put them into glass waist container
4 get broom or brush weep area and get small pieces depose in same place
5 take a wet wipe and cover area to pick up anything that as missed.
What is glassware?
Glassware has been refer to the any laboratory apparatus made of glass. When you are done using a glassware, wipe down the glassware to remove any cleaning solvent. They are often washed with a solvent and particles of the cleaning solvent adheres to the glassware.
A lot of our laboratory apparatus are made of glass e.g beakers, conical flask, measuring cylinders etc. These glassware must be properly cleaned after use.
These particles of the solvent must be wiped to remove these particles of cleaning solvent that could contaminate a sample placed in the glassware.

Which detail from the passage creates the most suspense for the reader?
“Minos, king of Crete, had made war upon Athens.”
“He had laid waste the fields and gardens round about Athens.”
“Then Aegeus, the king of Athens . . . went out to see King Minos and to treat with him.”
Answers
It is likely that the detail that creates the most suspense for the reader is "He [Minos] king of Crete, had made war upon Athens.”
What was the confrontation between Minos and Athenian ruler?
It is likely that the detail that creates the most suspense for the reader is "He [Minos] had sent word to the Athenian rulers that on the morrow he would march into their city with fire and sword and would slay all their young men and would pull down all their houses, even to the Temple of Athena, which stood on the great hill above the town."
This detail implies that the confrontation between Minos and the Athenian rulers will be violent and destructive, and the reader may be left wondering what will happen as a result. Additionally, the fact that Minos has already laid waste to the surrounding area and burned the merchant vessels in the harbor suggests that he is a formidable and potentially dangerous opponent, further increasing the suspense for the reader.
