Answer:
uracil
Explanation:
uracil is complenentary to adenine in transcription
The diagram below shows part of the process of DNA transcription. Uracil mRNA base will go in location 1.
What do you mean by DNA transcription?The process of turning a piece of DNA into RNA is called transcription. Messenger RNA is said to be produced when DNA segments are transcribed into RNA molecules that can encode proteins.
DNA record is the cycle by which the hereditary data held inside DNA is re-composed into courier RNA (mRNA) by RNA polymerase. After that, this mRNA leaves the nucleus and serves as the foundation for DNA translation.
The nucleus is where transcription takes place. An RNA (mRNA) molecule is produced by using DNA as a template. During record, a strand of mRNA is made that is corresponding to a strand of DNA.

Immediately following the arrival of the stimulus at the axon terminal there is a short period called the ________ period during which no muscle tension is observed while the neurotransmitter is being released by exocytosis, diffusing across the synaptic cleft, and binding to its receptor to activate the muscle cell. relaxation latent contraction refractory
Answer:
Immediately following the arrival of the stimulus at the axon terminal there is a short period called the latent period.
Explanation:
When a stimulus reaches the terminal of an axon, a period known as the latent period begins. This period has a short duration and during it it is possible to observe the blockage of new stimuli in the nerve fiber. Thus, the new stimuli fail to trigger an impulse and no muscle tension to be observed.
While the latent period is not finished, the neurotransmitter is released through the action of exocytosis that moves until it gets access to the receptor capable of activating the muscle cell.

Recently discovered genetic evidence shows that multicellular land plants such as corn and wheat, are all of one lineage – they all arose from a single type of algae. Fossil evidence suggests that other types of algae did not have the needed complexity to move into terrestrial ecosystems. Explain at least 3 adaptations that algae would need to be able to survive on land.
Answer:
1) they would need a host or vessel to stay on and feed of of their body
2) they would need some for of reproduction in the host ( mitosis whatever the algae my use )
3) they would need to wisely choose there hosts and of what they feed on so there host doesn’t die quickly
I don’t know if this is what your looking for but these are 3 things that algae would need to live

Factors that could affect the current oxygen and carbon dioxide levels?
Explanation:
There are many factors, both natural and man-made, that affect the levels of carbon dioxide and oxygen in the atmosphere. Some of them are:
Burning of fossil fuels increases the level of carbon dioxide.
Cleaning agricultural land increases the level of carbon dioxide.
The availability of nutrients in plants affects the synthesis of oxygen.
The intensity of the sunlight can increase or decrease the synthesis of oxygen.
Deforestation and industrial expansion greatly affect carbon dioxide and oxygen levels.
The increase in consumer products due to population explosion and advances in health care can also fluctuate carbon dioxide and oxygen levels.
An increase in oxygen levels is thought to promote healthy living in the environment, whereas a decrease in oxygen levels can lead to a decrease in atmospheric layers (thinning of the ozone layer). This reduction allows more sunlight to reach the Earth's surface. Sunlight gets trapped inside the Earth and raises the temperature of the planet. It is also known as global warming.
A reduction in carbon dioxide to a certain level is good for the environment, but lower than normal levels can affect oxygen synthesis as plants absorb carbon dioxide and use it to synthesize oxygen during photosynthesis. Since carbon dioxide is a greenhouse gas, an increase in its level will cause global warming.

Answer:
The correct answer is -
1. Lupus
2 Cardiovascular disease
3. Huntingtons disease
4. Cancer
5. Diabetes
Explanation:
Lupus is one of the autoimmune diseases that takes place when our bodywork against ourself and harm cells and skin. When an individual has poor or bad nutrition and generally experiences obesity this cardiovascular disease occurs.
Huntington's disease takes place due to changes in DNA in the brain and affects neurons of the brain. Cancer is uncontrollable cell growth that can be lethal. If an individual is not able to produce enough amount of insulin, that lowers the glucose from the blood, will lead to cell diabetes condition

What is the role of reverse transcriptase in DNA technologies?
A. To unzip DNA strands
B. To find mRNA
C. To produce proteins
O D. To make cDNA
Answer:
D...........................................................................
Explanation:
Reverse transcriptase may be a DNA polymerase enzyme that transcribes single-stranded RNA into DNA.
What is reverse transcriptase?
This enzyme is in a position to synthesize a double-stranded DNA into a single-strand DNA once the RNA is transcribed in 1st step. Found in retroviruses, like the human immunodeficiency virus (HIV).Reverse transcriptase is used to form a cDNA copy of the mRNA. The cDNA sample is then amplified by PCR. This yields multiple copies of cDNA without intronsThus, we can conclude that the correct option is D.
To make cDNA is the role of reverse transcriptase in DNA technologies.

Answer:
my my teacher gives my class and I a mystery box for us to observe what's inside that box it was closed, as we was trying to know what's inside that box we were looking and thinking what does it sounds like, but my friend next to me says it sounds like a stapler and my other friend said it's not very heavy, as we were we said we could take another box just like that identified box and put a stapler since it sounds like a stapler and it's not that heavy as we know staplers are not that heavy. well we did that we check and our activity shows that the mystery box it slides and appear to be flat and all the box it slides in appear to be flat so that's the same thing as our box and the mystery box and we were looking at how does it sound when we close the box and everything we were checking how does it sound as we are observed that the mystery box it makes a metallic song when it strikes the side of the box an hour box the stapler makes a thudding sound when it strikes the side of the box and we also checked if the mass of the box was the same but it wasn't the mystery box was 270 g and our box was much more heavier which is 410 g so we were checking what was the really wrong thing we was checking and checking is like what should we do next, and we did in for the things in the box had to be different because our observation of the two boxes are different, and we observed yes things are different of course.

Explanation:
describes the study of microbes in their natural habitats and the relationships between the microbes and that habitat.
Answer:
The study of microbes in their natural habitat and their relationship with each other and their environment is termed as Microbial ecology. It mainly constitutes of Viruses, Eukaryotes ,Bacteria and Archaea as its living entities.
Being omnipresent in the biosphere they impact the other life-forms up to a significant extent.
They also help maintaining biogeochemical cycle by nitrogen fixation, sulfur metabolism and methane metabolism. Microbes also play a vital role of availing energy in the ecosystems where sunlight is scarce and hence photosynthesis is not good means of energy trapping, in such ecosystems the microbes actively engage in fundamental ecological processes including production, decomposition, and fixation inside the host organism.

A population of fruit faces food shortage when the fruit trees they depend on for food begin to die from disease. What type of growth pattern will bats exhibit
Answer:
The correct answer is - logistic growth.
Explanation:
The growth of bats is only limited by the fruit trees they feed on. It is an example of the concept of carrying capacity of an environment, so this is best modelled by logistic growth.
The Types 1-3 of survival growth are related to age, while exponential growth does not have any limits related to environmental capacity.
The correct answer is - logistic growth.
