The maximum efficiency of a machine is less than 100% and is denoted as option C.

<h3>What is a Machine?</h3>

This is referred to as a device which is created to make work easier and multiplies the effect of human effort.

The maximum efficiency of a machine is usually less than 100% due to the factor known as friction which results in energy being lost.

A scientist notices that when she adds a small, water-soluble molecule to a dish of cells, the cells turn off transcription of a
Lelechka [254]

Answer:

Enzyme-linked

Explanation:

The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).

Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.

A sequence of biotic changes that regenerate or create an ecological community is known as?.
harina [27]

A sequence of biotic changes that regenerate or create an ecological community is known as ecological succession.

Ecological succession is the process of change in an ecological community's species composition over time. The time frame can span several decades or fewer (for instance, following a wildfire). The community grows through an increase in complexity from a small number of pioneering plants and animals to a stable or self-sustaining climax community.

Succession is a process that occurs after a disturbance or the early colonization of a new environment. It involves changes to an ecological community that are more or less predictable and orderly. Secondary succession refers to succession that occurs after a pre-existing community has been disrupted, whereas primary succession refers to succession that starts in new environments with no impact from pre-existing groups.

To know more about ecological succession, refer to the following link:
