Voltage-gated (voltage-dependent) channels and antiport carriers are both types of transporters. Thus, option (d) is correct.
What is Voltage-gated?
The term voltage-gated refers to the allowing or blocking of passage through a cell membrane in response to an electrical input.
Voltage-gated ion channels are membrane proteins that allow certain inorganic ions to cross cell membranes. An antiporter is a membrane protein that simultaneously transports two molecules in opposite directions.
As a result, both are the type of the transporters. Therefore, option (d) is correct.

Explanation:
Here's the complete question:
What type of context clue helps describe the meaning of the underlined term?
To the south and southeast of China are the Himalayas. These are the highest mountains in the world. They provided a nearly impassable border for ancient China, keeping the area isolated from many other civilizations.
A. inference
B. restatement
C. antonym or synonym
D. definition or explanation
The type of context clue that helps in describe the meaning of the underlined term which is impassable is referred to as inference. Inference simply means when one derives a conclusion from some states facts.
Answer:
by making my time table for that what I should do in this time
Plants that get nutrients from rocks will can cause chemical weathering. Generally there are two types of weathering processes: physical and chemical weathering and they result in the breakdown of rocks, minerals, etc. Plants contribute to both physical and chemical weathering. Plants that grow in fissures and cracks in the rocks, as they grow their roots extend. Over time, the rocks will be broken into smaller fragments. Many such plants also give off chemicals, most commonly humic acid. These acids help in the breakdown of iron and aluminum compounds in the subsurface. Plants also support microbial life forms that help in weathering of soil and minerals. All these process contribute to the weathering of rocks and minerals.
I hope i helped. Also sorry if there were any typos.
