Answer:

choanoflagellates and sponges are sister groups

Explanation:

The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.

Which factor in this swamp is abiotic?<br><br> A. Grass<br> B. Trees<br> C. Algae<br> D. Water
Lelechka [254]

Answer:

D. Water

Explanation:

Biotic factors are all living things, and they are derived from organisms. These include: fungi, plants, bacteria, archaea, protists, animals.

Abiotic factors are all nonliving things, and they are not derived from organisms. These include: air, soil, light, water, minerals.

In this case, grass, trees, and algae are all living things since they are derived from organisms.

On the other hand, water is not a living thing since it is not derived from organisms.

The half — life of nickel is 96 years. How much of a 30-gram sample is left after 270 years?
-Dominant- [34]

The amount of the 30 gram-sample that will remain after 270 years is 6.61 grams

<h3>How to determine the number of half-lives </h3>

We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:

  • Half-life (t½) = 96 years
  • Time (t) = 270 years
  • Number of half-lives (n) =?

n = t / t½

n = 270 / 99

n = 2.8125

<h3>How to determine the amount remaining </h3>
  • Original amount (N₀) = 30 grams
  • Number of half-lives (n) = 2.8125
  • Amount remaining (N) =?

The amount remaing can be obtained as follow:

N = N₀ / 2^n

N = 30 / 2^2.8125

N = 6.61 grams
