The true nucleus is not a homologous feature of Phylum Porifera. So, it's B.
What do you mean by Porifera?Porifera may be defined as superficial invertebrate animals that live in aquatic habitats that comprise the sponges.
Organisms belonging to animals, plants, and fungi only have a true nucleus. The members of the phylum Porifera majorly consist of sponges that have a system of suspension feeders that filter food out of the water.
The members of the phylum Porifera have choanocytes that specify the cells that sweep water into the body.
Therefore, the correct option for this question is B.

This is how a SIM medium looks after 24 hours and the addition of indole reagent. Is the unknown bacterium positive or negative for H2S production, indole production, and motility
In the test tube pink colour shows that it is indole positive and H2S positive bacteria and it is non motile.
What is the indole positive?Within seconds of introducing the reagent, a pink color appears in the reagent layer on top of the agar deep, indicating a positive indole test. The reagent layer will stay yellow or slightly hazy if the culture is indole negative.
When an organism converts sulfur to hydrogen sulfide, the hydrogen sulfide reacts with iron to generate ferric sulfide, a black precipitate. The presence of blackening in the medium suggests a reduction in sulfur, which is a +ve sign.

3. Describe how nutrient cycles can interact in the cycling of matter:
Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.
What is nutrient cycles?Nutrients move through the ecosystem in the nutrient cycle or biogeochemical cycles. This cycle is a pathway by which a chemical element moves or recycles through the biotic and abiotic factors of an ecosystem.
It is inclusive of the biotic factors, or living organisms such as plants animals, and others, as well as abiotic or nonliving such as air, soil, and water.
it moves through abiotic and biotic elements such as water moves through water body to the atmosphere by evaporation and moves back to earth and hydrosphere by rain and also used by living organisms.

Looking at the picture, describe the biotic and abiotic factors you see.
Answer:
abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organismsBiotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem

4. Define free energy, and explain how its change is calculated.
We can calculate the change in free energy for a reaction under nonstandard conditions by using the ΔG = ΔH - TΔS equation.
How do we calculate chnage in free energy?Change in gibbs free energy of any reaction will be calculated by uisng the below equation as:
ΔG = ΔH - TΔS, where
ΔH = change in enthalpy
T = temperature of reaction
ΔS = chnage in entropy
By putting all given values we can calculate the gibbs free energy of the reaction, and negative sign of energy shows the spontaneity of the reaction.
Hence by using the enthalpy, entropy and temperature we can calculate the free energy change.

Free energy refers to the energy in a system that is free to do work i.e. the internal energy minus any energy that is unavailable to perform work.
Why is use of free energy?Free energy is used to determine how systems change and how much work they can produce. It is expressed in two forms: the Helmholtz free energy F, sometimes called the work function, and the Gibbs free energy G.
The free energy change of a reaction can be calculated using the following expression: ΔG∘=ΔH∘−TΔS∘. where ΔG=free energy change.
