In eukaryotes, gene expression is regulated mostly by _____.
Answer:
Gene expression in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription.
Explanation:
In eukaryotes, gene expression is regulated mostly by transcription factors.
What are transcription factors?Transcription factors are proteins that bind to DNA in the promoter region of a gene, and they play a critical role in controlling when and to what extent a gene is expressed.
They can either activate or repress gene expression by promoting or inhibiting the recruitment of RNA polymerase. Transcription factors are themselves regulated by a variety of signals, including hormones, growth factors, and other external cues, as well as by feedback loops and other regulatory mechanisms within the cell.
Ultimately, this complex interplay of factors allows eukaryotic cells to precisely control which genes are expressed, when they are expressed, and to what degree, enabling them to respond to changing internal and external environments.

what happens to the i band when the sarcomere contracts
Answer:
The A band stays the same width and, at full contraction, the thin filaments overlap. ... The I band contains only thin filaments and also shortens. The A band does not shorten—it remains the same length—but A bands of different sarcomeres move closer together during contraction, eventually disappearing.

write your own description of what the sliding filament theory states.
Answer:
The sliding filament theory is the explanation for how muscles contract to produce force. As we have mentioned on previous pages, the actin and myosin filaments within the sarcomeres of muscle fibres bind to create cross-bridges and slide past one another, creating a contraction.

what is the function of the filaments found in ranges 1-2 and 6-7 but no other ranges?
Answer:
What is the function of the filaments found in ranges 1-2 and 6-7 but no other ranges? Elastic (titin) filaments help to protect the muscle from overstretching and also aid in returning it to normal length. This enzyme breaks down acetylcholine into acetic acid and choline.

Explain how the method of nutrition used by wild pine differs from the method of nutrition used by other organisms (animals)
Answer:
Most plants are auto trophic able to use sunlight as their primary source of energy,in a process called photosynthesis.This process enables them to turn carbon dioxide from the air into food,The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide.
All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement.
What is the difference between El Nino and La Nina in science terms of climate?
Answer:
El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of it. El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
Hope this helps
Answer:
Well, El Niño(warmer environment) impacts weather systems around the world, while La Nina(cold environment) tends to have global climate affects opposite to El Nino.
which muscle group relates best with the term midline?
The oblique is the muscle group that best relates with the term midline.
The anterolateral abdominal wall contains a muscle group in which there are flat muscles whose fibers originate in the posterolateral part, pass forward and become an aponeurosis towards the midline:
The external oblique muscle is the thickest and most superficial of the three muscles on the lateral wall of the abdomen.It follows an inferomedial direction and the muscle-tendon limit descends in such a way that, towards the midline and also below the height of the anterior superior iliac spine, it is completely transformed into an aponeurosis.The aponeurosis of the external oblique joins that of the internal oblique and passes in front of the rectus abdominis; its fibers intersect in the midline with those on the opposite side and contribute to the linea alba.
Therefore, we can conclude that the oblique is the muscle group that best relates with the term midline.

Which of the following is a disadvantage of genetic engineering?
May cause negative side effects
Cannot create new organisms
Reduces the nutrition value of food
Increases the scarcity of food in the world
Answer:
may cause negative side effects
Explanation:
Answer:
May cause negative side effects.
Explanation:
I took the test
Genetic Engineering is used to put genes from one organisms into another. The new organism can reproduce. And while it may seem like it's the answer the nutrition value and scarcity of food is in no way impacted. It's not like cloning. Where more are being created in large amounts with similar diets. They can be cross-pollinated with organisms with different diets. So the only obvious answer would be the negative side effects.
