What are the differences between prokaryotic and eukaryotic gene expression? Group of answer choices Regulation of transcription is identical in both.
Answer:
See the answer below
Explanation:
The gene expression involves a series of steps that have to do with encoding the information in genes as mRNA - transcription - and the translation of the codes into proteins - translation.
The process of transcription and translation happens within the same space in prokaryotic cells. Since they have neither nuclei nor membrane-bound organelles, both transcription and translation happen in the cytoplasmic space of the cell simultaneously.
However, in eukaryotic cells, transcription happens in the nucleus because the DNA is located within it. Once this takes place, the mRNA produced is transported outside the nucleus into the cytoplasm where they engage with the ribosome and tRNA in a translation process.

Which of these is not an example of an adaptation for terrestrial living that may have arisen by convergent evolution? The water-to-land transition occurred independently several times in the protostomes. Which of these is not an example of an adaptation for terrestrial living that may have arisen by convergent evolution? Internal respiratory structures Eggs with a covering that minimizes water loss Internal fertilization Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air
Answer:
The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air
Explanation:
the fundamental problem that an aquatic animals face during its progress to land to save the egg or embryo from parching. So they have developed cleidoic eggs where undeveloped organism stay implanted inside extra embryonic layers, for example, amnions and are secured in egg shells. These eggs have minute pores so embryo can make gas exchange.
This egg shells forestall water misfortune. Interior treatment, however are available in certain sharks, yet it is for the most part a variation of land creatures. Explicit intromittent organs have been created for moving of sperm in to female. In contrast with water , gaseous movement is in land creatures is happen through advancement of lungs which contain numerous alveoli where gaseous exchange is occurred. Decreased surface to volume ratio decrease productivity of gas exchange , not increment.
Thus, The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air

Answer:
The statement "All living things are composed of eukaryotic cells" is incorrect and is not a part of Cell Theory
Explanation:
Eukaryotic organisms are not the only living things in existence. Micro organisms such as bacteria are referred to as prokaryotic. This classification is done on the basis of the presence or the absence of a nucleus. Eukaryotic organism are more evolved and contain a well defined nuclear structure.

Which action would most likely increase the amount of carbon in the environment? A. Choosing to burn coal to generate electricity B. Using energy-efficient appliances in place of older, traditional appliances C. Reusing shopping bags instead of using disposable plastic bags D. Recycling paper and plastic instead of throwing it in the trash
Answer:
Choosing to burn coal to generate electicity
Explanation:
Burning coals to generate electricity is most likely to increase the amount of carbon in the environment because it emits carbon dioxide, hence option A is correct.
Why does burning coals increase the amount of carbon?When coal burns its carbon is combined with oxygen to produce more amount of carbon dioxide, for generating electricity coal burns is producing a large amount of carbon.
If fuel burns its oxygen reacts with carbon in the air forming carbon dioxide or reacts with hydrogen to form water vapor.
Using energy-efficient appliances in place of older, traditional appliances, has less chance to produce excess amounts of carbon in the environment. Recycling things also reduces the amount of carbon in the environment.
Therefore, choosing to burn coal to generate electricity is the correct option.

Botany Professor. Dr. Noa Nkembe. is conducting research over how temperature effects the toxicity of Toxicodendron diversilobum (poison oak). He grows the plant in controlled environments that are kept at temperatures that vary by just 0.05 degrees Celsius. Which of the thermometers would be the BEST choice for him to use for this experiment? Justify your answer. Glass thermometer Temperature probe Temperature strip
Answer:
Glass Thermometer
Explanation:
Glass oral thermometers typically have markings every 0.1 °C or 0.2 °F. Basal temperature is stable enough to require accuracy of at least 0.05 °C or 0.1 °F, so special glass basal thermometers are distinct from glass oral thermometers.

why are white blood cells unable to transport gases
Answer:
The majority of oxygen in the body is transported by hemoglobin, which is found inside red blood cells.
Explanation:
Although oxygen dissolves in blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen, 98.5 percent, is bound to a protein called hemoglobin and carried to the tissues.

Base pairs are nucleotides that are the structural unit of the genetic material. Bases code for the traits that are in the form of genes. Thus, option B is correct.
What are genes?Genes are the primary unit involved in heredity and are composed of nucleotides that make the DNA. They are involved in the production of proteins through the process of translation.
Genes are made of alleles that code the traits inherited from the parents through the method of reproduction. The dominant alleles are expressed whereas the recessive are masked and not visible in the phenotype.
The alleles are made of chromosomes and DNA that are in turn made of nucleotide sequences, sugar, and a phosphate group.

Compare the inputs and outputs of humans and robots in terms of matter and energy.
Answer: In contrast to human stance control, robot stance control is at an early stage of evolution. The need for some form of stance control system has been recognized during the recent rapid development of humanoid robots (see Mahboobin et al., 2008). However, the design of most robot balance systems has not taken advantage of existing knowledge of human stance control systems. A possible reason for this is that engineers focused on the obviously important interaction that occurs at the interface between the robot’s feet and the ground
