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.

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.

Answer:

A cell body, an axon, and dendrites.

Explanation:

The similar characteristics of different neurons is their body structure which have the common parts in all neurons. All neurons have three essential parts i.e. a cell body, an axon, and dendrites. Neurons different in size, shape, and structure due to different in their role and location but all these different neurons have the same components of its structure such as  cell body, an axon, and dendrites.

Answer:

its known as pertussis,caused by a bacteria called bordetella pertussis

Answer:

Due to no controlling agent for harmful microbes that causes new pandemic.

Explanation:

The new pandemic leads to imbalance of ecosystem due to biodiversity loss because the absence of antimicrobial agent causes the pandemic. The antimicrobial agent is responsible for the control of harmful microorganism so due to disturbance in the ecosystem, the biodiversity losses occurs and there is no organism which stop or control the population of the harmful organism that causes new pandemic.

Answer:

Logistic Growth Model

Explanation:

The logistic model is realistic because it suggests the fact that the population of species is regulated and controlled by the carrying capacity (maximum members that an ecosystem supports) of the ecosystem. The population becomes small when the carrying capacity decreases.

Answer:

b: moon attraction to the sun

Answer:

Amino acid generated from tyrosines and tryptophan (end in '-ine') and includes adrenaline and norepinephrine. The (produced by the adrenal medulla). Thyroxine (production from the thyroid gland) and melatonin are also included in the amino acid hormones (produced by the pineal gland).

Explanation:

The main control over hormone production and release is negative feedback. The stimulation causes the release of a chemical in negative feedback systems; once it reaches a specific level, the substance sends a signal stopping further discharge.

This ensures a narrow range of the levels of hormones in the blood.

For example, blood glucose is controlled via negative feedback to secrete insulin and glucagons.

Answer:

I've grown potatoes on top of loose earth that's covered by a thick layer of loose straw. It allows the green leafy parts to easily push through to the sunlight above while keeping developing tubers protected from light. I've grown them this way because I really enjoy the taste of fresh new potatoes and have no desire to store mature potatoes for winter. I want to get the most baby potatoes possible while not damaging the plants with tiny potatoes not big enough to eat yet. It also keeps the potatoes cleaner than if grown under the soil.

When I start lifting the straw back to pick the largest new potatoes, I can see the development of the other potatoes. While the biggest potatoes are 1 1/2 to 2 inches in size, others range in size all the way down to 1/4 inch or less.

When a specific garden plant blooms, most of the flowers open within a very short time period. Now think of tomato plants. The flowers continue to open over a period of months and both ripe tomatoes, large and small green tomatoes as well as flowers can all be found on the same plant. Not all the fruit will be ripe before cold weather kills the plant.

Potatoes are closely related to tomatoes and like tomatoes, not all the tubers will be full size when the plant dies back. So I'd say it's neither genetics nor environmental factors but the inherent life and growth cycle of potatoes that account for the tuber size difference.

The difference in the tuber size in plants of potatoes and tomatoes does not depend upon its genetics or environmental factors rather it depends upon the inherent life and growth cycle of the plant.

Growth cycles are the recurrent fluctuations in the series of deviations from the usual trend of the plant growth. Thus, the growth cycle contractions in the plant include slowdowns as well as absolute declines in the activity, whereas business cycles contractions include only the absolute declines or recessions.

Potatoes are the plant species which are closely related to tomatoes and just like tomatoes, not all the tubers will be full size when the plant dies back in time. So, it is neither the genetics nor the environmental factors but the inherent life and growth cycle of the potato plants that account for the tuber size difference in the plants which are genetically identical to each other.

Answer:

Chemical energy from food molecules (potential energy) may also be transformed to mechanical energy (kinetic energy) when the body moves. In every energy transformation, some energy is given off as heat. This is why the body warms up during different activities like exercising, lifting weights, and even digestion!

Answer:

Respiratory bronchiole  

Explanation:

The respiratory bronchioles represent the narrowest airways within the lung, being continuations of terminal bronchioles that have approx. 0.5 mm in size. The epithelium of the respiratory bronchiole is composed of cuboidal ciliated cells and a small number of non-ciliated (secretory) Clara cells. The respiratory bronchioles lead into alveolar ducts composed of smooth muscle and connective tissue (i.e., elastin and collagen), connecting the respiratory bronchioles to the alveolar sacs.

Answer:

In the founding population, the allele frequency is different from the original bigger-sized population. The size of the new population affects this difference even more. Some of the alleles will tend to increase, while some others will tend to decrease in frequency.

Explanation:

Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.  

Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.  

Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.  

Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, settle down in a new area and reproduce. The new and small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.
