Adenine
Thymine
Cytosine
Guanine
Answers
Answer:
The order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.
DNA and complementary base pairing
The deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.
In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).
According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.
In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

Adenosine triphosphate (ATP) is a cell's energy currency. All of the following statements about ATP are true, except ATP is used to lower activation energy in enzymatic reactions.
A) ATP is used to lower the activation energy in enzymatic reactions.How does ATP affect enzyme activity?Enzymes allow chemical reactions to proceed with activation energy provided by the catabolism of ATP. When cells convert glucose and oxygen into carbon dioxide and water, they use 2 molecules of ATP as activation energy and gain 36 to 38 molecules of ATP in return. Without enzymes, this would not be possible.

The two required components to initiate transcription on the gene are:
Transcription factors that bind to the promoter sequences Mediator proteins - binds to enhancer and promoter regions in the gene.What is transcription of a gene?Transcription of a gene is the process by which the information present in the gene is used to produce the messenger RNA molecule by RNA polymerase.
A gene is a sequence in the DNA molecule which codes for a particular gene product.
The process of transcription is important or the first step which is required in the production of the gene product of a gene.
In order for transcription of a gene to be initiated, certain components are required. These components include:
Transcription factors - these are proteins that bind to the promoter sequences as well as other regulatory sequences in the gene. The binding of transcription factors helps to recruit RNA polymerase to the site for transcription to begin.Mediator proteins - these are proteins which form part of the RNA polymerase complex.

Develop a plan to test the hardness of a sample of feldspar using the following items : glass plate , copper penny and a streak plate
Answers
Feldspar has a hardness of 6 and they improve the toughness durability and strength of the ceramic body.
The feldspar is considered the group of rocks which forms the aluminum tectosilicate minerals and they also contain other types of cations such as sodium, barium, potassium, and calcium.
The minerals that scratch the glass they have to be harder than 5.5 inches and feldspar can be used on a glass plate to do this feldspar is needed to run over anything which is harder than 6 inches otherwise detecting hardness is hard.
A copper penny has a hardness of about three hence the hardness test by a copper penny is not possible by a feldspar.
A streak plate has a hardness of over 6.5 to 7 and that is why it can be used to detect the hardness as feldspar has a hardness of 6 it can be run over the streak plate and a test can be done.
The benefits of feldspar are it has good dispersibility, has high chemical inertness so is not much reactive, ph is stable, resistant to abrasion highly, it has low viscosity at high filler loading and it cannot get frozen and also has a good refractive index.
it is fine-milled graded and used in many different products.

ivan is investigating the path of home runs in baseball
Answers
The correct answer is the last option which states the distance that each home run travels.
This is because, the main aim of Ivan is to investigate the path of home runs in baseball. And, the best way to do so would be to calculate the distance that each home run travels. By studying the time of the day when each home run is hit, he won't be able to examine the path. It would rather be more useful to see at what time the frequency of home runs is the maximum. The scores of the game would also not reveal the path travelled by the home runs as they are not calculated on the basis of the distance travelled. Similarly, the names of the players hitting the home runs might not provide the necessary information for this experiment.Thus, the correct answer is the distance that each home run travels.

If a mosquito bites your arm. You feel the sting, jump, and slap the mosquito the body’s organ systems that are involved are nervous system and muscular system.
What is the nervous sistem?The nervous system is the one that will transmit the signals through the body thanks to the brain and they will also be transmitted in the opposite way. Thanks to this we can have control of our abilities to move, think, breathe, among others. Also through the collection of sensory, heat and painful stimuli we can prevent damage to the body by responding by removing the part of the body that receives the damage through a reflex, such as hitting the mosquito when feeling the itch.
