Answer:
weathering
erosion
Explanation:
Weathering can be explained as the
breaking down of rocks as well as minerals or dissolving it on the surface of the earth. After the rock has been broken down then the bits of the rock can be transported away in a process known as " Erosion". The agents of
weathering and erosion could be water, salt, animal as well as plants.
It should be noted that the parts of sedimentary rocks formation that include the breakdown is weathering while the parts of sedimentary rocks formation that include carrying away of existing rock is erosion.
Producing plastics benefits the economy by employing workers and it helps the economy of every state by spending billions of dollars on shipping plastic products.
Hope this helps! Have a good day.
<span>Answer: T-cells are made to identify antigens, while inflammation fights anything in the affected area
</span>
The adaptive immune cells are made of B-cell and T-cell. The function of B-cells is to produce antibodies, while T-cells will detect antigens of the pathogen. If T-cells detect an antigen from a cell, it will assume that the cells are infected. It will send a signal to the infected cells which tell them to do apoptosis. Inflammation is not specific, which makes them not strong.
Answer:b.are required for the expression of specific protein-encoding genes
Explanation:
Transcription factors are proteins that bind to enzyme RNA polymerase to aid transcription( coping of information on DNA to an intermediate mRNA.
They control the expression of a particular gene. A transcriptor can be a repressor or enhancer. A repressor when they inhibit the action of RNA polymerase by blocking it from attaching to promoter sequence or enhancer by binding to RNA polymerase to enhance transcription.
Transcriptor protein can work alone or work with other protein such as silencer.
