After decades of studying extraterrestrial organisms on Triton, you and your colleagues have developed a pretty good cladogram (

not yet time-calibrated) of alien life, and have developed a good understanding of species ranges and distributions. Use no more than 2 sentences or bullet points per subpart. (a) One clade of aliens has significantly many orders of magnitude more putative species than any of its close relative clades. What is one potential hypothesis for this phylogenetic pattern that we discussed in class?- (b) You observe a strong latitudinal diversity gradient on Triton that is analogous to the one we find on Earth for many clades. Briefly describe this observation, and propose one explanation for this pattern

Answer:

The effect might be due to the gene expression.

Explanation:

The effect might be due to the variation in the gene expression in the organism. In this way, the variety of the genetic pool is likely to result in a diversity of the gene pool or genome. Because of the mutation and the environmental factors, there is likely to be a slight variation of the species. This results in a slight difference in the phenotypic expression.

Korolek [52]

Answer:

I believe it would be these:

He can replace the 1.5-volt battery with a battery of higher voltage.

He can use a longer piece of wire that wraps more times around the bolt.

I'm not sure the others would work

What is the connection between the rising concentration of SO2 And NO2x , And The Acid Rain Pollution Alert?
sweet-ann [11.9K]

Answer:

Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6

Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.

When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.

Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.

The best way to measure an exact volume is with a(n) _____________.
xxTIMURxx [149]
The answer is E, graduated cylinder.

Meanwhile beaker and test tubes may have markings, but they're not as accurate. Especially in beakers, their wide diameter only makes an approximate volume, as it is very likely to have a reading mistake on that. Their main function is not to measure volumes, thus there marking may already have an mistake.

And in watch glass and evaporating dish, they're both very shallow and wide in diameter too, so they're not for measuring volumes. Plus, not all of them have markings.

And in graduated cylinder, the thin shape makes the reading a lot more accurate and the main purpose for that is to measure volumes. They also come in transparent tubes that can make the reading clear and easy to read.

A student draws a fence with several gate as part of a model of cellular transport explain what defence indicates represent blam
Oksi-84 [34.3K]

The given question says that a student has constructed a model of cellular transport using fences and several gates.  

This model can be used to demonstrate the cellular transport.

The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.  

Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.

Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.
