You are conducting a photosynthesis experiment to determine how much oxygen is produced over a 24-hour period of time. You are measuring the oxygen production every hour for 24 hours.
Answer:
Measure only daytime.
Explanation:
It is useless to measure the oxygen production every hour for 24 hours because oxygen is produced during day time due to the presence of photosynthesis process. Oxygen is produced in large amount during photosynthesis, some oxygen is used in respiration while the remaining diffuse out from plant body through stomata. After vanishing sunlight, the photosynthesis process stop and no production of oxygen occur. So only measure oxygen production at daytime as compared to every hour for 24 hours.
Why is it important for molecules to able to travel into and out o your body's cells?
The function of the transport proteins is to maintain the internal environment of the cell's salt, nutritional, and protein balance within a range that ensures the survival of the cell and the organism.
What is importance of a molecule to move across the cell?Biology places a great deal of importance on the passage of substances into and out of cells (for example, nutrients into and poisons out), as without it, no cell and hence no organism could survive for very long.
Moving chemicals throughout the body is essential for living cells. Transporting chemicals into and out of cells is necessary.
Examples include oxygen, carbon dioxide, and dissolved food. Active transport, osmosis, and diffusion are used to accomplish this.
Therefore, transport of a molecule into and out of cell is important to functioning of cell.

Quantitative data measures categories like color or movie genre.
True
False
Answer:
[tex]\boxed {\tt False}[/tex]
Explanation:
First, let's define quantitative data.
Quantitative data is
Data that can be expressed as a number or a quantity. This type of data can be measured, for example: length, temperature, time, etc.There is also another kind of data, called qualitative data.
Qualitative data is
Data that is expressed with descriptions. This type of data is observed. Examples include: colors, smells, tastes, etc.We are asked about color and movie genre. This can't be measured or expressed as a number, so it is not quantitative data. Instead, it is qualitative data.
2. What is the protoplasm surrounding the nucleus
called?
Answer:
Protoplasm is composed of a mixture of small molecules such as amino acids, monosaccharides and water, and macromolecules such as nucleic acids, proteins, lipids and polysaccharides. In eukaryotes the protoplasm surrounding the cell nucleus are actually known as the cytoplasym and that inside the nucleus as the nucleoplasms.
A mineral forms from water at the edge of a lake. Which statement best describes this mineral? The mineral formed from lava. The mineral formed through evaporation. The mineral formed when hot water cooled. The mineral crystallized from magma.
Answer:
The mineral formed through evaporation.
Explanation:
Minerals are inorganic substances that occur naturally i.e. not man-made. These minerals are formed in different ways in nature. One of those ways is through EVAPORATION.
Since water dissolves a lot of substances including the particles of these minerals, the mineral components can be found in a dissolved state in water bodies e.g lakes, oceans etc. However, when heat increases and the water molecules evaporate (change to gas), the dissolved minerals in these water bodies crystallize out.
This is what happens when minerals form at the edge of a lake. The water from the lake evaporates leading to the formation of minerals.
Answer:
The mineral formed through evaporation.

Describe ways in which a healthy artery differs from an artery affected by coronary heart disease
Answer:
A healthy artery is wider and has no blockages. The lumen (which is the hole in the centre of the artery), is open and clear. This means there is more blood flow. An artery of a person suffering from coronary heart disease is often blocked, usually by a fatty deposit. This means the blood does not flow as well. (See diagram, in which I would draw two arteries, one with a blockage of fatty deposit, one clear and healthy).

How did endosymbiosis impact the structural differences between bacteria, animals, plants and fungi?
Answer:DNA, RNA, Ribosomes and Protein Synthesis
This provided the first substantial evidence for the endosymbiosis hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.
Explanation:
What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.
A tide table shows the date, time, and height of the predicted tides. What type of tide is the following table representing, semidiurnal, mixed semidiurnal, or diurnal? Date Day Time Height 11/30 Mon 11:58 am 6.34 H 11/30 Mon 11:43 pm 2.16 L 12/1 Tues 11:01 am 6.27 H 12/1 Tues 11:30 pm 1.99 L
Answer:
the date
Explanation:
A tide table shows the date, time, and height of the predicted tides. The type of tide that the given table represents is mixed semidiurnal.
What is a mixed semidiurnal tide?A mixed semidiurnal tide is a tide that has two high tides and two low tides of different magnitudes in each day. The interval between consecutive high tides or low tides is almost the same.
The height of the tides changes every day due to the gravitational pull of the Sun and the Moon on the Earth's ocean water. The influence of the Moon on tidal patterns is more significant than that of the Sun.
Therefore, a mixed semidiurnal tide is the one with two high and two low tides of different magnitudes in each day, which is represented by the given tide table. All of these characteristics indicate a semidiurnal tide pattern.
