snow_tiger [21]

Answer:

Ambulacraria

Explanation:

Ambulacraria or Coelomopora is an invertebrate clade that encompasses the Echinodermata and Hemichordata within the deuterostomies. This grouping is considered Chordata's sister taxon because it has a common ancestor.

The phylum Chordata is considered the last within the evolutionary range and comprises all vertebrates and some invertebrates such as amphioxus and tunicates. The main feature of this phylum is the presence of notochord in at least one of its embryonic phases. In vertebrates, the notochord will later make room for the Vertebral Column.

PARTA
erastovalidia [21]

Answer:

A. The bacteria are breaking down sugars in the absence of oxygen.

Explanation:

Bacteria are microscopic single-celled organims. These organisms may produce their own source of chemical energy, or consume and absorb chemical energy made by producers.

They break down chemical energy like glucose through lactic acid fermentation in their cytoplasm, without the presence of oxygen.

In Glycolysis:

2 molecules of ATP are used to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electron carrying NADH molecules. Since 2 ATP are used, a net 2ATP are produced by this process.

Then, pyruvate is converted to lactic acid, producing 2 NAD+, used as electron carriers.

Imagine that part of a population of South American finches is blown by a storm onto an island far offshore and manages to survi
lina2011 [118]

Answer: The observation "A" leads us to conclude that the finches populations are from two different species

Explanation:

According to the biological concept of species, <em>a set of individuals are from the same species if they are able to reproduce and leave fertile offspring</em>. This is key so one species can be successful and perpetuate through time. If they cannot leave descendants, then the species will be extinct. However, it’s possible that two individuals from different species mate and have descendants, but they cannot leave fertile offspring. When they are from different species, the offspring will be sterile and it is called a hybrid.  

In the case of the South American finch, the island's finch population and mainland's finch population belong to different species because their offspring is sterile. To have different features, as different feather's color, or to have other dietary preference is not enough to say that they are different species. This is because within the same species, individuals can have variations. For example, we can different eye color and belong to the same species.

Two linebackers tackle a quarterback. One hit him with a force of 105 N and the other hit him with a force of 150 N. They are bo
Setler [38]

The net force on the quarterback when he is hit by two linebackers running eastwards is 255N.

Force is a vector quantity, we must recall that if two forces act in the same direction, we obtain the net force by adding the two forces together. If two forces act in opposite direction, we obtain the net force by subtracting the forces from each other.

Since the both linebackers are running East, the net force is obtained as; 105 N + 150 N = 255 N.
