Hey,

The cell wall is an extra protective layer around the plasma membrane, and allows for plant protection from bacteria, water etc. The Golgi apparatus is an organelle within plant cells that modifies, packages, and transports proteins and lipids throughout the cell. Chloroplasts are organelles within plant cells that are responsible for photosynthesis. They contain thylakoids and the stroma. The cell membrane (aka plasma membrane) is made up mainly of phospholipids. It is selectively permeable, meaning it only allows certain substances to pass, usually small, non-polar particles. Ribosomes are the sites of protein synthesis, or where proteins are built. Hope that helps!

Answer:

Cell wall: A protective layer covering the outside of the cell. They keep the shape of the plant cell, prevent water loss, and provide support.

golgi apparatus: Transports proteins and lipids around the cell. Often it is called the shipping department of the cell.

chloroplast: Chloroplasts store chlorophyll and this is where photosynthesis takes place in the cell.

Cell membrane: A layer that covers the cell, acts as a gate and determines what comes and goes through the cell. It allows good things in, while keeping others out.

Intermediate filaments: Provides support when when the plant cell comes into contact with other cells.

Ribosome: The part of the cell that is responsible for creating proteins.

Anton [14]
"The Calvin cycle, Calvin–Benson–Bassham (CBB) cycle, reductive pentose phosphate cycle or C3 cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms. ... This set of reactions is also called carbon fixation. The key enzyme of the cycle is called RuBisCO."

xeze [42]

Answer:

The process that Mildred used is known as Radiocarbon dating

Note: The question is incomplete. The complete question is given below:

Mildred collects a sample of fossilized plant material. She takes it back to her lab to run some tests on it. Mildred is able to measure the amount of carbon-14 in her sample and compare this to the amount of carbon-12 in it. She uses this information to calculate that the fossil is 4,500 year old. The process that Mildred used is known as _______

Radiocarbon dating

Faulting

Indexing

Superposition

Explanation:

Radiocarbon dating is a process of determining the age estimates of various objects and materials using the radioactive properties of an isotope of carbon, carbon-14.

Radiocarbon dating uses the ratio of two isotopes of carbon, carbon-12 and carbon-14 present in materials which contains carbon to determine their age.

There is a fairly constant ratio of carbon-12 and carbon-14 in living organisms. However, at death, due to the decay of carbon-14 to carbon-12, the ratio begins to change. Since the rate of decay of carbon-14 is fairly constant, a property known as half-life, the time it has taken for carbon-14 to decay to carbon-12 can be calculated. This calculated time will givee the age of the fossilised material.
