Answer:
The Archaea, the Bacteria, and the Eucarya.
Explanation:
The Archaea, Bacteria, and Eucarya are the three kingdoms of life. Archaea and Bacteria possess prokaryotic cell structures, but the category Eucarya (eukaryotes) includes cells with a nuclear that separates the genetic information from either the cytoplasm.
A student combined equal amounts of two solutions. One solution had a pH of 2 and the other had a pH of 12. Which would most likely be the resulting pH?
Answer:
This question lacks options, the options are:
A. 1
B. 3
C. 6
D. 11
The answer is C. 6
Explanation:
pH of a solution refers to the concentration of hydrogen ions in that solution. A scale is used to measure pH of a solution.
* A pH value less than (<) 7 is said to be ACIDIC. The lesser the number, the more acidic
* A pH value of exactly 7 is said to be NEUTRAL
* A pH value above (>) 7 is said to be BASIC OR ALKALINE. The higher the number, the more alkaline.
According to this question, two solutions of equal volume with pH values of 2 and 12 respectively were combined. Based on the explanation of pH scale, the solution with pH 2 is said to be very ACIDIC while the solution with pH 12 is said to be very ALKALINE.
Hence, if this two solutions are combined, a neutralization will occur which will result to a solution with close to neutral pH (7). In the above options, 6 is the closest pH value to NEUTRAL and hence, the most likely pH of the resulting solution.

Write two sentences or clues, one for each word, that will help you remember the difference between actin and myosin. (Example: Actin is actively pulled)?
Answer:
The correct answer is -
Actin produces thin contractile filaments within muscle cells,
Myosin produces the dense contractile filaments within muscle cells
Explanation:
Actin is a globular protein that makes actin filaments by arranging in the long spiral chain or produces thin contractile filaments within muscle cells. It is found in cell cytoplasm as well as in the nucleus in eukaryotic cells.
Myosin is a motor protein that produces the dense contractile filaments within muscle cells and plays role in generating movement and force from chemical energy.
Discuss the impact of development planning for economic development for a development country like Pakistan under what circumstances a country should go for short term medium term and long term plan (it is a economics question)
Answer:
Great impact.
Explanation:
There is a great impact of development planning for economic development for a country because this development planning is important for the growth of economy of the country. Without planning, goals of better economy can not be accomplished. A country should go for short term plan in order to solve the economic problem at that time while on the other hand, medium and long term plan is used by the country in order to solve the economic problem completely.
Autoclaving is the most effective among all moist heat-related antimicrobial methods. (True or False)
Answer:
True.
Explanation:
Autoclaving is the most effective among all moist heat-related antimicrobial methods because this method can kill all the harmful microbes such as bacteria, fungi and viruses. Moist heat causes destruction of microorganisms by denaturation of macromolecules that is present in their body such as proteins. Autoclaving is a very common method for moist sterilization. It is an effective method in killing fungi, bacteria, spores, and viruses but it does not eliminate prions.

During pulmonary ventilation, relaxation of the diaphragm and external intercostals ________ and air flows out of the lungs. increases the pressure in the thoracic cavity flattens the floor of the thoracic cavity increases the volume of the thoracic cavity expands the rib cage stimulates the phrenic nerve
Answer:
Increases the pressure in the thoracic cavity
Explanation:
During pulmonary ventilation, relaxation of the diaphragm and external intercostals increases the pressure in the thoracic cavity and air flows out of the lungs.
Pulmonary ventilation involves the exchange of air in the body. The exchange mainly takes place between the lungs and the the blood. When the lungs take in oxygen it distributes it to other parts of the body after which the byproduct is expelled in the form of Carbon dioxide.
The diaphragm and intercostal muscles are found close to the chest(thoracic) region such that when air is expelled it produces a similar effect such as relaxation of the diaphragm which also makes the chest muscles go down and exert pressure. This mechanism aids the expulsion of Carbon dioxide from the lungs.
Why do you think gene therapy is such a promising field for this disease?
Answer:
Gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve your body's ability to fight disease. Gene therapy holds promise for treating a wide range of diseases, such as cancer, cystic fibrosis, heart disease, diabetes, hemophilia and AIDS.

GIVE BRAINLISTThe BRCA-1 genes in humans encode proteins that have role in maintaining DNA stability. Mutation in this gene results in formation of non-functional protein, which is not able to repair damaged DNA, resulting in a significantly increased risk of breast cancer. BRCA-1 is a/an: Group of answer choices Proto-oncogene Homeotic gene Oncogene Tumor suppressor gene
Answer:
tumor suppressor gene
Explanation:
A tumor suppressor gene is capable of modulating cellular processes during cell division and/or replication, thereby avoiding uncontrolled cell proliferation and tumor development. For example, the p53 gene is a tumor suppressor gene that encodes a protein (p53) which is well known to regulate critical cellular processes such as, for example, cell cycle arrest and programmed cell death (apoptosis). Moreover, breast cancer genes BRCA1 and BRCA2 are tumor suppressor genes that regulate the repair of damaged DNA through the Homologous recombination (HR) pathway. In consequence, mutations in BRCA1 and BRCA2 genes can increase the risk of developing breast cancer.

Identify the fossil dating methods that are appropriate to use in determining the age of the fossil primates. Correct Dating Methods inquizitive
Answer:
The correct dating methods will be:
radiopotassium datingbiostratigraphic datingExplanation:
The primate fossils presented in the question above must be submitted to the dating processes known as radiopotassium and biostratigraphic so that the age of these fossils can be determined as accurately as possible.
Radiopotassium dating is based on the half-life of potassium, which is equal to 40 years. The term half-life refers to the number of years it takes for half the number of atoms of the radioactive isotope to be destroyed. Thus, radiopotassium dating measures the amount of potassium present in a fossil and relates this amount to the half-life of potassium, thus being able to calculate the age of the fossil.
Biostratigraphic dating, on the other hand, allows the age of a fossil to be determined by being compared with the age of another fossil and the physical and structural composition that these fossils have.
Therefore, to determine the age of primate fossils, radiopotassium dating would first be used in some fossils. These would be used as a model during biostratigraphic dating, allowing confirmation of the age of other fossils.
