The common characteristic of those two organisms is hard spherical shells (exoskeleton).

Foraminiferans are single cell marine eukaryotes divided into granular endoplasm and transparent ectoplasm. Foraminiferans are enveloped with tests, hard shells, usually composed of calcium carbonate (sometimes from organic compounds or silica).

Coccolithophore is a unicellular, eukaryotic alga with special calcium carbonate plates (or scales) of uncertain function (coccoliths). Each unicellular alga is enclosed in its own collection of coccoliths, the which make up its exoskeleton- coccosphere.

The other answer is correct, but more specifically:

D. They both develop calcium carbonate structures.

The addition of calcium carbonate makes exoskeletons harder/stronger.

Consider the equation S + O2 ? SO2. What is the product? Question 3 options: S SO 2 S + SO 2 O 2

Keith_Richards [23]

Answer : The product in the given balanced reaction is, sulfur dioxide $(SO_2)$ .

Explanation :

The balanced chemical reaction will be,

$S+O_2\rightarrow SO_2$

This reaction occurs when sulfur react with oxygen gas to give sulfur dioxide gas as a product.

In the given balanced chemical reaction, sulfur (S) and oxygen gas $(O_2)$ are the reactants and sulfur dioxide $(SO_2)$ is the product.

Hence, the product in the given balanced reaction is, sulfur dioxide $(SO_2)$ .

Which part of a green plant makes most of the plants food?

ikadub [295]

Answer:

Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose which is sugar. This energy rich sugar is the source of food used by most plants.

Answer:

Volume of rectangular prism = 81 feet³

Explanation:

Volume of rectangular prism is same as volume of cuboid

Length = 9 ft

Width = 4 ft

Height = 2 $\frac{1}{4}$ ft = $\frac{9}{4}$ ft

Volume of rectangular prism = Length × Width × Height

= 9 × 4 × $\frac{9}{4}$

= 36 × $\frac{9}{4}$

= $\frac{324}{4}$

= 81 feet³

The phase in the life cycle of a plant that produces spores

DanielleElmas [232]

Answer:

Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. After reaching maturity, the diploid sporophyte produces spores by meiosis, which in turn divide by mitosis to produce the haploid gametophyte. The new gametophyte produces gametes, and the cycle continues.
