What else can I help you with?
Is a eukaryotic cell has organelles surrounded by membranes true or false?
true
Proteins are assembled in the nucleus of a cell?
false
Crossing the international date line changes the date not the hour is this true or false?
False. Crossing the International Date Line changes both the date and the hour. When crossing from east to west, you move forward a day, and when crossing from west to east, you move back a day.
Does the stroma separate the inner and outer membranes of the mitochondria?
No, the stroma is found in chloroplasts, not mitochondria. In mitochondria, the inner and outer membranes are separated by the intermembrane space.
True or false some proteins within a cell can be viewed with the naked eye?
False. Proteins are typically not visible to the naked eye as they are microscopic in size. They can only be visualized using specialized techniques such as microscopy or biochemical assays.
Is this question true or false most polar molecules cannot cross cell membranes without the help of certain proteins?
true
The dark reactions occur within the thylakoid membranes true or false?
False. False.
Are membranes selectively permeable if they allow only certain substances to move across them?
False.
Dark reactions occur within the thylakoid membranes?
It's a true and false question, the answer is: False
Is a eukaryotic cell has organelles surrounded by membranes true or false?
true
Proteins are assembled in the nucleus of a cell?
false
Proteins are assembled in the nucleus of the cell?
False!!
Do proteins at the inner surface of the plasma membrane attach to the membrane to the cells support the structure?
Yes, proteins at the inner surface of the plasma membrane can attach to the cytoskeleton of the cell, providing support and helping to maintain the structure of the membrane. These membrane-associated proteins interact with the cytoskeleton to anchor the membrane in place and facilitate cell shape and movement.
Crossing the international date line changes the date not the hour is this true or false?
False. Crossing the International Date Line changes both the date and the hour. When crossing from east to west, you move forward a day, and when crossing from west to east, you move back a day.
Is the 20 different polysaccharides used to make proteins true or false?
Is the 20 different polysaccharides used to make proteins true or false?
Is this true or false proteins can be used interchangeably in the body because they have similar structures?
False. Proteins have very specific shapes and functions and cannot be used interchangeably.
Is the following sentence true or false Both chloroplasts and mitochondria are enclosed by two envelope membranes?
True. Both chloroplasts and mitochondria have a double-membrane envelope that surrounds their organelle structures.
