Sponges belong to the Phylum Porifera and hence are one of the most primitive organisms. The sponge would not be impacted by the drug.

Their bodies are asymmetrical. frame form can be cylindrical, vase-like, rounded or sac-like. they're diploblastic animals with layers, the outer dermal layer and the internal gastral layer. there's a gelatinous, non-cell mesoglea, in among these layers.

The phylum Porifera comprises the sponges. Sponges are simple invertebrate animals that live in aquatic habitats. despite the fact that the general public of sponges are marine, some species stay in freshwater lakes and streams.

Most sponges are hermaphroditic male and female cells exist in one animal and reproduce by using freeing spermatozoan into the water present day to be carried to other sponges, wherein they interact with eggs. Sponges also can reproduce.

scientists believe the earth likely warmed between 0.65 celsius and 1.05 celsius with an average value of 0.85 celsius between y
scoray [572]

Answer:

The lower limit is 0.65°C

The upper limit is 1.05°C

the average is 0.85°C

The difference between the average and the lower limit is:

0.85°C - 0.65°C = 0.20°C

the difference between th average and the upper limit is:

0.85°C - 1.05°C = -0.20°C

Then we can write the change in temperature as:

T = 0.85°C ± 0.20°C

Now we want to find the error bar.

The error bar would be the total distance between the lowest value and the largest value.

Then the error bar is:

1.05°C - 0.65°C = 0.40°C

notice that the error bar is twice the error, which makes a lot of sense because the error (± 0.20°C) goes up and down.

Then the error bar in this measure has a magnitude of 0.40°C.

Answer to Question 1

Population --> Whole Organism --> Organ system --> Organ --> Tissue --> Cell

Explanation:

- The cell is the simplest, basic and functional unit of life.

- Tissue is a collection of similar cells e.g brain tissue

- Organ is a collection of similar tissues e.g Liver, Lungs

- Organ system refers to a group of closely related organs performing the same function in an organism.

- Organism comprises of well-coordinated organ systems.

- Population refers to the total number of organisms living and breeding together.

Answer to Question 2

Cell --> Genome --> Gene --> Nucleotide

Explanation:

A cell consists of a nucleus and other organelles. Within the nucleus & other organelles like mitochondria lies the total genetic material of the cell known as GENOME.

- The genome contains several functional sequence of bases known as GENE.

Vacuoles are structures found in many cells. Their job is to store materials needed for the cell. Paramecia and other unicellula

Contractile means the ability of an organism to<u><em> withhold, reduce in size or shrink. </em></u>

<u><em /></u>

<u><em /></u>

A contractile vacuole will help this organism better survive in its moist environment by <u><em>preventing or stopping the cell from absorbing too much water from its moist environment.</em></u>

<u><em /></u>

<u><em /></u>

  • A contractile vacuole is an <em>organelle</em> that can be found in organisms that are said to be <u><em>single-celled (Unicellular organisms).</em></u>

  • One of the primary functions of a contractile vacuole is to absorb <u><em>excess water</em></u> from the protoplasm in the unicellular organism and release this water to the surrounding environment.

  • A contractile vacuole can be called the excretory organ of unicellular organisms. This is because it is involved in <u><em>osmoregulation.</em></u>
