Explanation:
when storing fruits and vegetables in her apartment, what steps can julie take to minimize nutrient losses? check all that apply.
Nutrient loss is the reduction or elimination of the nutrients in food. Nutrients are very important in the development of cells in the body and also giving energy and vitality to the bones.
Please note that your question is incomplete, so i am giving you a general overview.
Some of the factors that leads to nutrient loss in food includes:
Overcooking (exposure to high level of heat)FreezingDrying, etc.Therefore, to minimise nutrient loss, it is vital that food is well preserved and is finished immediately, to reduce or totally eliminate the need to freeze, overcook or reheat food.

Lacrimal
Explanation:
How do muscle cells access what they need to keep producing energy
Muscle cells access what they need to continue producing energy through chemical energy from ATP to transform it into mechanical energy.
Muscle cells are elongated cells whose length can reach several centimeters.
The muscle uses ATP (energy) to carry out conformational changes in its molecular structure => variation in the length of the sarcomere.
Adenosine triphosphate (ATP) is the basic source of energy for muscle contraction.
Each link stores 7300 calories of energy per mole of ATP under normal conditions and when a phosphate radical is separated from the molecule, these calories are available providing the energy necessary for muscle contraction.
The muscle cell has three mechanisms to resynthesize ATP:
ATP synthesis through phosphocreatine.
Anaerobic glycolysis process with the transformation of muscle glycogen into lactate.
From oxidative phosphorylation.
ATP synthesis through phosphocreatine consists of the transfer of energy from phosphocreatine to ADP so that it can reincorporate a phosphate group to its molecule and transform it into ATP.
So the energy that has been released in the hydrolysis of PCr is directly used to resynthesize ATP from ADP.
Therefore, we can conclude that muscle cells access what they need to continue producing energy through the chemical energy of ATP to transform it into mechanical energy.

Why does neurones contain many mitochondria and many ribosomes?
Answer:
Neurons depend on mitochondria. ATP generation by mitochondrial respiration in the brain consumes 20% of the body's oxygen although the brain is only 2% of the mass of the body (Attwell and Laughlin, 2001). ... Every part of the neuron requires ATP and therefore requires mitochondria to be present.The dendritic processes and spines of neurons are essentially expansions of cytoplasm containing most of the organelles found in the cell body. ... Rough endoplasmic reticulum and ribosomes are present in large but not small dendrites.

1. describe the stages of the cell cycle
2. use a model to illustrate the role of cellular division in the formation of new cells
3. describe the structure of a chromosome
4. follow chromosomes through the processes of mitosis and cytokinesis
Answer:
1.The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.
2. In the Picture Linked.
3. Chromosome help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a centromere, which divides the chromosome into two sections – the p (short) arm and the q (long) arm.
4. Mitosis occurs at the sites of growth and development of new tissues. Here are the stage of mitosis Below:
Prophase
This is the initial phase. The chromosomes in the nucleus become visible as thin coiled threads. In animals, the centrosome found in the cytoplasm divides to form two centrioles. The chromosomes become tightly coiled and shorter. From each centriole, fine fibers develop and elongate to form spindle apparatus. The nucleolus becomes dispersed in the nucleus and disappears. The nuclear membrane also break and disappears.
Metaphase
The pairs of chromatids align along the equator of the spindle apparatus and are attached to it at their centromeres.
Anaphase
The centromere of each chromosome splits and the chromatids separate. Each chromatid moves to the opposite poles of the cell. The chromatids appear as V--shaped.
Telophase
The spindle fibers disintegrate and disappear. New nuclear membrane forma around each set of chromatids. A nucleolus develops in the nucleus of each daughter cell. The cytoplasm now divides in a process called cytokinesis. In animals, an invagination develops at the plasmalemma near the equator of the cell.
Relationship between mitosis and cytokinesis:
Mitosis is the division of a nucleus. Cytokinesis is the division of the cytoplasm. If mitosis occurred without cytokinesis, the cell would contain two nuclei and twice the DNA. If cytokinesis occurred without mitosis , one of the new cells would lack DNA and a nucleus altogether.
