Describe three reasons that why meiosis is important
I) For gametes formation
II) For pollen grain formation
III) For seed formation
The importance of meiosis are:
- gamete formation
During meiosis, sex cells such as sperms and ova are formed in the testes and ovary respectively
- pollen grain formation
Pollen grain are formed in the anthers of flowering plants
- Seed formation
Seeds also known as ovules, are formed in the ovary of flowering plants
The same amino acid can be carried by different tRNA's.
Question 3 options:
right answer is "False"\
because every tRNA has its specific amino acid
HELP PLEASEEEEE How do advances in technology improve the study of anatomy and physiology?
A. They allow scientists to use inquiry skills such as observing, predicting, analyzing, and drawing conclusions.
B. They allow scientists to perform new investigations and test new ideas they may not have been able to do in the past.
C. They allow scientists to investigate the anatomy of actual specimens, such as cadavers, instead of using models or simulations.
D. They allow scientists to use the scientific method, which past scientists could not use as effectively.
Answer: B. They allow scientists to perform new investigations and test new ideas they may not have been able to do in the past.
The science is the discipline which includes information about nature and natural phenomena. Technology is the field of science which utilizes the knowledge of science for research and innovation. The advancement in technology can be used to perform the investigations and perform tests related so as to answer questions or queries related to the field of anatomy and physiology. It can help in conducting research and solving problems which were not solved in the past related to anatomy and physiology.
This lab explores three common cancers. an additional form of cancer – skin cancer – used to be seen only in older individuals but is now seen in younger individuals, many in their early 20s. skin cancer results from accumulated mutations to the dna of skin cells, caused primarily by sun exposure. what factors do you think may be contributing to the increase in skin cancer among young adults?
Due to pollution the ozone layer of the Earth is being more and more affected. The main function of ozone is to absorb the Sun's UV radiation. Exposure to UV radiation is known to increase the risk of skin cancers.
Thus, young adults could get higher levels of UV radiation from the sun compared with their grandparents, due to pollution.
Increased sun exposure may also be another cause. Today, it is more and more popular to spend a lot of time at the beach. Traveling to other countries to do this is more accessible today for young adults.
However, tanning beds which are very popular with young people, are another source of high levels of UV radiation.
Sometimes new information results in minor changes to a theory. But sometimes new information results in a theory being discarded as incorrect. An example of an incorrect theory that was disproved by the discovery of new information is Ptolemy’s theory of the solar system.
the original cell theory.
the germ theory.
plate tectonic theory.
The Ptolemy's theory of the solar system was disproved by the discovery of the new information. The Ptolemy's theory stated that the Earth is at the center of the solar system and all the planets, suns and stars orbited around it while the Earth stayed completely stationary. However, this theory was proven to be false as the sun-centeric model of the solar system better explained various phenomenon, such as the particular movement of the planets.
Hence, the correct answer is 'Ptolemy's theory of the solar system'.
Which statement describes the effects of farming practices such as the overuse of pesticides? A. More areas have fertile soil, reducing crop production.
B. Fewer areas have fertile soil, increasing crop production.
C. Fewer areas have fertile soil, reducing crop production.
D. More areas have fertile soil, increasing crop production.
It's C. Fewer areas have fertile soil, reducing crop production. APEX
The correct answer is option C
Overuse of pesticide can be harmful to the soil. It can make soil non fertile if used in a large amount again and again.
The areas of fertile soil will decrease due to the overuse of pesticides and as a result of this the area of fertile soil is reduced.
Less area of fertile soil will have reduced crop production.
Combining tobacco products with alcohol does not increase your risk of cancer of the esophagus
The answer is false because those two products when mixed could increase a chance of the person’s life of having an illness or disease and it usually leads to serious complications such as having cancer in the esophagus. That is why the statement is false because it increase the chance of the person having the cancer.
