What do the rib muscles and diaphragm have in common?

Biology
1 answer:
Hatshy [7]2 years ago
3 0

Answer:

Both are breathing muscles

Explanation:

When rib muscles and the diaphragm contract they increase the volume of the chest cavity, increasing the air pressure outside the body, causing air to rush into the lungs to fill the vacuum created by the increase in volume.

Name

Date: May 1st

Date completed: May 12th

Hypothesis: I believe the seeds will grow 1-2 feet based on my research

Procedure: I put my seeds in small pots and put on a self I have outside in the sun. They can absorb good sunlight this way

Growth of seeds: all varied but stayed within 3 feet

Type of seeds:
1. Cornflowers

Growth
Day 3: about 2 inches
Day 6: about 5 inches
Day 9: about 12 inches
Day 12: about 22 inches
Day 15: about 34 inches

Interpretations: cornflower- the meaning is wealth, prosperity, fortune and friendship.

I don’t know what was asked in the lab...

Conclusion: my hypothesis was kind of correct. My cornflowers grew to be over 2 feet, but not by much. Some even stayed under, but not by much I say again. This was a fun and educational experience and I learned a lot about this wonderful plant. I hade no idea that it was even a real thing before this project! I learned that different flowers grow at different paces, even if they get the same amount of sunlight and water.

This procedure for measuring cell size has certain limitations . List three such limitations​
marusya05 [52]

The limitations of cell size are:

1) Surface area to volume ratio

2) Nucleo cytoplasmic ratio

3) Fragility of cell membrane

What are the cause of limitations on cell size?

The need for a surface area of sufficient area to allow the cells function→.

→If the surface area of cell increase volume increase to the cube of the linear increase.

→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.

Examples are muscle cells.

There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. M
Feliz [49]

Answer:

cumulative dilution = 0.000001

Explanation:

A serial dilution is a stepwise kind of dilution repeated a certain number of times, in which the concentration reduces exponentially each time.

The cumulative dilution is the final dilution gotten depending on the number of times dilution has been done and the dilution factor. The formula is given as:

Cumulative dilution = (F)ⁿ

where:

F = dilution factor = 0.1

n = number of serial dilutions = 6

∴ cumulative dilution = (0.1)⁶ = 0.000001

What is the main difference between aerobic respiration and anaerobic respiration?
garri49 [273]
The main difference between aerobic respiration and anaerobic respiration is that aerobic using oxygen in the reaction, while anaerobic does not.

Even though both aerobic and anaerobic respiration releases energy, but their reactants and other products are completely different.
For example in human, in aerobic respiration, oxygen and glucose reacts to give out carbon dioxide and water; while in anaerobic respiration, which usually happens during exercise when oxygen is not enough, the muscle cells uses only glucose to produce energy and lactic acid.

Therefore, the main difference is where aerobic uses oxygen, and anaerobic don’t.
