Answer and explanation;

Nucleus; houses a cell's DNA and its processes include protein, replication and packaging for cell division. It is also the site for transcription.

Cytosol; coordinates a responsible to the environment, metabolism and motor proteins.

Endomembrane system; includes the nuclear envelope (surrounds nucleus), rough and smooth ER, golgi body, lysosomes?vacuoles, peroxisome and plasma membrane.

Semiautonomous organelles; mitochondria (animals) and chloroplast (plants) which provide energy for the cell.

If the net force an object at rest is zero the object will remain at rest. <br> True or false
FromTheMoon [43]

True

Explanation:

If the net force on an object at rest is zero, the object will remain at rest. This is one of the postulates of newton's law of motion.

 Newton's first law of motion states that "an object will continue in its state of rest or uniform motion unless if it is acted upon by an external force. "

  • If no net force acts on a body, it will forever remain at rest.
  • The force on a body causes its motion and acceleration.
  • A body will continue in uniform motion if no external force acts on it.

Why is it important to study grouse habitat selection and demography relative to human land use practices?
nadya68 [22]
Grouse species have evolved living in environments with little vertical structure and in areas with minimum human activity (from roads and cultivation to other more complex infrastructure). In the recent decades, there has been a significant increase in wind energy development in diverse areas and ecosystems. This development involves construction and placement of tall man-made structures, such as wind turbines and other infrastructure in habitats with high wind capacity. These habitats are often occupied by grouse species. This coexistence could severely endanger the species survivorship and reproductive ability. It is very important to study grouse habitat selection and demography, so that appropriate regulatory guidelines can be applied to wind energy development.

The data in the table has been converted into a bar graph, as shown below. Amount of Carbohydrates in Fruit mc026-1.jpg mc026-2.
natita [175]
The reason that provides the best explanation of why a bar graph was selected to show the data in the table is that Bar graphs are used to compare separate items.
A bar graph is a visual tool that uses bars to compare data among categories. It may run horizontally or vertically such that the longer the graph the greater its value. A bar graph or bar charts uses bars to show comparisons between categories of data. It will always have two axis, one being generally numerical values, and the other describing the types of categories being compared.
