Answer:
Metaphase
Explanation:
Metaphase is the phase of mitosis that starts with complete disintegration of nuclear envelop. It is marked by attachment of spindle fibers to the kinetochores of chromosomes and movement of chromosomes to the middle of the cell, that is, equator. Chromosomes are aligned along center of the cell through spindle fibres .
A tiltmeter is a volcanic monitoring tool that measures ground swelling.
A tiltmeter is an instrument that is used to determine if the elevation of the earth crust has changed. Tiltmeters measures the angle of an object with regards to gravity. Tiltmeters are highly used in monitoring dams, volcanoes, hydraulic fractures and landslides.
Answer: Carbon Dioxide
Explanation: This deep, quick breathing changes the gas exchange in your lungs. Normally, you breathe in oxygen and breathe out carbon dioxide. But when you hyperventilate, the you breathe out more carbon dioxide than usual so that levels in your bloodstream drop.
B) the study of animal taxonomy
C) the study of animal physiology
Answer: A) The study of animal behaviour.
Explanation: B) the study of animal taxonomy is called taxonomy.
C) the study of animal physiology is zoology.
With that being said, we are left with A being the correct choice.
A usual heart rate in case of adults varies from 60 to 100 beats per minute. Usually, a lower heart rate at rest signifies more effective functioning of heart and better cardiovascular fitness. For example, a well-trained athlete may possess a usual resting heart rate closer to 40 beats in a minute.
The following is the correct order to measure the heart rate:
1. Make a fist.
2. Find a radial artery.
3. Feel a pulse.
4. Count for 10 seconds.
5. Multiply by 6.
Global warming can be affected by deforestation because the removal of tress affects the level of carbon dioxide in the environment. The level of carbon dioxide increase with a decrease in the number of trees that cause global warming.
Further Explanation:
The deforestation or the removal of vegetation from the shore can result in soil erosion. The soil erosion will result in the loss of nutrients rich soil. These nutrients are essential for the development of algae and plants. Global warming is a serious concern because of two reasons: Rapid warming of the Earth leads to rapid environmental changes making it difficult for species to adapt. Over time, natural habitats have become limited because of the resilience to climatic changes caused by global warming. The increased human population leading to urbanization and deforestation resulted in these changes. The increase in the human population leads to an increase in their needs for survival. They started to disrupt the food chains by removing predators. They hunted animals for food and other needs. They removed trees for their shelter. These human activities lead to a change in the environment and habitat.
