A scientist was observing a specimen under a microscope. He obtained the specimen from pond water. He observed that the specimen

was egg-shaped, had hairy structures all over its body, and was covered by a membrane. He also noticed two nuclei in the specimen’s body. To which phylum did the organism belong?
A) sarcodina
B) ciliophora
C) apicomplexa
D) euglenoid

It would have to be ciliophora because of the hair-like structures.

The correct answer is option B, that is, Ciliophora.  

Ciliophora is the term used for the phylum usually known as the ciliates. Ciliates are the most complex of cells, exhibiting an elaborate cytoskeleton, cilia, two distinct types of nuclei. Ciliates are single-celled species, which at a certain phase of their life cycle, possesses cilia, that is, short hair-like projections used for food gathering and locomotion.

1. The effect of initial population sizes on the growth of populations of an organism was
ella [17]

When graphing data, we must consider the variables, label axes, define units of measure. In this case, variables are initial population size / final population size, showing an directly proportional relationship.

-------------------------------------

We need to construct a graph illustrating the data in the table.

We can make a <u>dispersion graph</u>. To do it, we need to define variables.

Since we want to know how <em>different initial population sizes affect population growth, </em>

  • the independent variable is the initial population size
  • the dependent variable is the final population size (after 24 hours)

The final population size depends on the initial population size. This is, <em>the number of individuals at the beginning will </em><em>influence</em><em> the final number of individuals</em>.

  • Initial population sizes ⇒X horizontal ax ⇒Unit: Number of individuals
  • Final population sizes ⇒ Y vertical ax ⇒ Unit: Number of individuals

By making a dispersion graph, we can represent the effect of the varying initial population sizes on the final population sizes. We can compare these effects and observe how populations grow as the N₀ increases.

We can also choose a <u>bar graph</u>. In this way, we can compare initial and final population sizes.

This graph will show populations and two bars per population.

  • Blue bar ⇒N₀⇒ Initial population size
  • Red bar ⇒N₁ ⇒ Final population size
  • Different populations ⇒ 1, 2, 3, 4, 5 ⇒ Represented in the X horizontal ax
  • The number of individuals ⇒ from 1 to 324 ⇒ Represented in the Y vertical ax.

By making a bar graph, we can represent initial and final population sizes and compare them. <em>The population that begins with 1 individual, after 24 hours has 4 individuals. The population that begins with 3 individuals, ends with 9 individuals. And so on</em>.

No matter which graph you choose, you will observe a directly proportional relationship between both variables. The bigger is the initial population size, the bigger it ends after 24 hs.

When two species compete for the same ecological niche, they cannot coexist because they are competing for the exact same resour
zalisa [80]
The correct answer is B. competitive exclusion.
This law refers to the fact that it is nearly impossible for two species to exist in the same place at the same time together, if they are interested in the same resources. If both species need the same thing to survive, one will have to be stronger while the other one will dwindle in number.
