which scientists are credited for the events described in the develolment of the cell theory?
Answer:
The scientists credited with formulating the postulates of the cell theory are Matthias Schleiden, Theodor Schwann and Rudolf Virchow.
Explanation:
Cell Theory contributed to the understanding of how living organisms are made up of cells, as well as the role that cells play in life related functions.
The experiences of Schleiden, Schwann and Virchow laid the foundations of cell biology, whose main conclusions are summarized in the three postulates of Cell theory:
The cell is the basic structural and functional unit of life. All living beings are made up of one or more cells. All cells originate from other cells.Matthias Schleiden, when observing plant tissue under a microscope, was able to prove that this tissue was made up of cells, and that all plants possessed them. In 1837 he would postulate that the cell is the fundamental unit of life and that all plants were made up of cells.
A similar experience to that of Schleiden, but with animal tissue, was carried out in 1838 by the German physiologist Theodor Schwann, where he could conclude that in animal tissue there were also cells. This gave way to the second postulate that all living organisms are made up of cells.
In 1863, while studying cancer, the anatomist Rudolf Virchow observed how cells were able to reproduce themselves and give rise to new cells. The third postulate of the theory is due to this scientist, who was able to conclude that every living cell originates from another cell.
1.Excess carbon dioxide is harmful to
the oceans because
A. they product carbonic acid form
the atmospheric carbon
B. it removes most of the dissolved
oxygen
C. it decreases the rate of evaporation
Increased levels of CO2 make the ocean more acidic and put sea organisms in danger. This could mean slower growth in the world's corals reefs, which are already stressed and dying from the warmer ocean temperatures associated with increased greenhouse gases in the atmosphere.
What are the causes and effects of ocean acidification?Ocean acidification is mainly driven by carbon dioxide gas in the climate dissolving into the sea.
This directs to a lowering of the water's pH, making the sea more acidic. Many factors contribute to rising carbon dioxide levels.
Thus, correct option is "A" they product carbonic acid form the atmospheric carbon.

Given the DNA sequence 3'TACCGAGGCATT 5', what is the transcribed mRNA sequence?
5
3'
4
4
Please help !!!
Answer:
The correct answer is - 5' AUGGCUCCUAA 3' .
Explanation:
DNA has four nitrogenous bases that are Thymine (T), guanine (G), cytosine (C) and adenine (A) arranged in it make a code. During transcription, the DNA template is transcribed into messenger RNA which is complementary to the DNA code.
RNA and DNA both have four bases but in RNA there is uracil (U) present instead of thymine which is complementary to the adenosine and also the ends are reversed so it can translate properly. U is complementary to A, C is complementary to G, and vice versa.
So, for DNA sequence - 3'TACCGAGGCATT 5'
mRNA would be 5' AUGGCUCCUAA 3'.
Which major type of air mass typically brings cool, dry weather? maritime polar continental polar maritime tropical continental tropical
Answer:
b on eng 2020-2021
Explanation:
Air mass is defined as the volume of air that is determined by the temperature and water vapor content. The air mass is divided into four categories, which are maritime polar, continental polar, maritime tropical, and continental tropical.
The correct answer is:
Option B. continental polar
Continental polar air masses are generally cold and dry because they arise from the continental region. The air mass is stable and originates over Canada and Alaska. The continental polar are marked by the surface high pressure, cold temperatures, and low dew points.
The maritime tropical air mass is warm, moist, and unstable, whereas the continental tropical air mass is originated from the low-altitude desert and is characterized by negligible rainfall.
Therefore, option B is correct.

Describe two communication differences between the nervous system and endocrine system.
The nervous system uses an electrical messaging system requiring a short time and endocrine system uses a chemical system requiring a longer time.
What are functions of nervous and endocrine system?Both the nervous system and the endocrine system work to coordinate the functions of the body. They secrete substances to carry their functions, which reach the effector organs.
The organs comprising the nervous system are brain, spinal cord and the remaining peripheral nerves. The endocrine system is comprised of glands.
The functions of endocrine system are carried by the hormones and the functions of nervous system are carried out by neurotransmitters. The hormones are secreted by the glands into the bloodstream. The neurotransmitters are secreted by the neurons into the connecting neuron.
Therefore, the mechanism of action of endocrine system takes longer to cause effect than the nervous system.

nurse? Select all that apply.
doctoral program
two-year college
four-year college
certification
Answer:
What is required to become a nurse is two-year college or four-year college
and certification.
Explanation:
The nurses are in charge of the care of the patients and the administration of medicines, in addition to other activities that pursue the integral care of the sick person. To do this, nurses must receive training and demonstrate their ability to do the job.
Nursing training can be accomplished through various programs, including an associate's degree in nursing, a diploma, or a bachelor's degree, which can be completed in two, three, or four years, respectively.
After their studies, nurses must demonstrate their skills and knowledge in order to be certified —in addition to college— by institutions such as American Nurses Credentialing Center Certifications.
Doctoral program is a higher degree that requires more years of study and is not initially required to become a nurse.

Energy is stored in organic compounds during the process of cellular respiration and then released during the process of photosynthesis. Thus, Option A is correct.
what are the factors affecting photosynthesis?It is a process by which autotrophic plant and bacteria use light energy as a source to make sugar from water and carbon dioxide.
They convert light energy into chemical energy which is stored in the form of starch.
The surface of Leaves have chloroplast which absorb light energy.
[tex]\rm 6\;CO_2\;+\;6\;H_2O\;\rightarrow\;C_6H_{12}O_6\;+\;6\;O_2\\\\[/tex]
Th factors affecting photosynthesis are the intensity of light energy increased then rate of photosynthesis also enhanced.
Higher concentration of carbon dioxide induces the rate of photosynthesis. The average range CO2 needed is from 300 – 400 PPM
The adequate temperature needed between 25° to 35° C and water is an important factor, the scarcity leads to refusal of stomatal opening to retain the amount of water.

What is the primary specie of leaf insects?
You will notice that some lineages (e.g. the descendants of species 56) branched many times and are represented by many living species. Discuss the ecological conditions that you think might result in the rapid diversification of some lineages. Use the caminalcules as examples. Think about what environmental conditions drove these particular caminalcules to evolve (A real world example would be the diversification of the mammals at the beginning of the Cenozoic, right after the dinosaurs went extinct.)
Answer:
The environment selects the lineage which better fits their specializations in the available resources.
Explanation:
The possible motive that lineages demonstrated quickly diversification might happen because the environment contained the opportunities which the lineages took as an opportunity to evolve. The environment could have benefited some species rather than others which could lead to different specializations of different lineages. For example, after the downfall of the dominance of dinosaurs, mammals had a few new environments to evolve with new resources, this led to more lineage biodiversification.
The environment choose the lineage that better fits their specializations in the available resources.
