Answer:
Mitosis is closely controlled by the genes inside every cell. They continue to replicate rapidly without the control systems that normal cells have. Cancer cells will form lumps, or tumours, that damage the surrounding tissues.

Answer:
Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length
Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length
The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).
The inference procedure uses the information collected from the sample in order to obtain one conclusion. Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
Answer: The correct answer is option c.
Explanation:
Cardiac conduction system is formed by specialized cardiac muscle cells which enable the heart to contract in coordinated fashion.
The main component of this system are:
- Sinoatrial node
- Atrioventricular node
- Bundle of His
- Branched bundle
- Punkinje fibers
SA node consists of cells known as pacemaker cells. These cells spontaneously generate action potentials which lead to the contraction of atria.
These potentials are then passed to AV node which relay them to bundle of His. These bundles are branched into right and left bundle which ultimately transfer these potentials to Purkinje fibers.
The potentials from these fibers lead to the contraction of ventricles.
Answer:
Chloroplast
Explanation:
Fungi organisims are complete eukaurions, either it is plury or unicelular, it will allways have a definited nucleus, Golgi apparatus, reticulum, vesicles, and other. Generally, they have mitochondrions as machinary to get ATP; but some lesser, and specific fungis like thoses in the order Microsporidian, lost them through evolution.
Either way, a fungi does not have chloroplast, being an chemeotroffic organism, it have to adquire carbon and nitrogen sources from others.
