Answer:
Chromatin is responsible for gene expression.
Explanation:
Chromatin is responsible for gene expression because chromatin contains DNA that has all information about genes. chromatin controls the gene in order to form encoded products. DNA in chromatin send information to the RNA to produce specific types of proteins that are needed by the organisms for its growth and development so in that way the genes can be expressed in the organism.

How do seeds germinate?
HELP NOW
Seeds remain dormant or inactive until conditions are right for germination. All seeds need water, oxygen, and proper temperature in order to germinate. ... Then the seed coat breaks open and a root or radicle emerges first, followed by the shoot or plumule that contains the leaves and stem.

Think of some traits in people, plants, or animals. Describe one trait and tell whether you think the trait is a dominant/recessive, multiple allele, codominant, incompletely dominant, sex-linked, or polygenic trait.
Answer:
Non-Mendelian inheritance
Multiple alleles, incomplete dominance, and codominance
Explanation:
In the real world, genes often come in many versions (alleles). Alleles aren't always fully dominant or recessive to one another, but may instead display codominance or incomplete dominance.
what are protons and electrons are compressed into. Plz hurry
Answer:
The electrons in degenerate matter are compressed so closely together that they more-or-less behave as if the entire star is one huge quantum system. They form an electron gas, and behave very much like a highly pressurized fluid inside the star. (Protons and neutrons have their own quantum states, thank you.)
Answer:
They compress into neutrons.
How many times longer is DNA than it is wide?
Answer:
About 200 km 7.
DNA is approximately six times longer than it is wide after measurements.
DNA is a 2-nanometer-diameter double-stranded molecule. Rise per base pair is 0.34 nanometers. Divide length by width to calculate length-to-width ratio. The length-to-width ratio is 6:1 due to DNA's stable diameter and base pair distance. DNA is six times longer than broad.
DNA stores and encodes genetic information efficiently in this elongated shape. DNA molecules can range from a few hundred base pairs in bacterial genomes to millions or billions in sophisticated animals. DNA stores and transmits life's genetic blueprints because it's longer than it is wide.

Why do we need friction in our world?
Friction is a force that works against motion. While walking, friction helps us maintain our stability and prevents us from slipping. Friction also works the same way with cars and vehicles in general, preventing them from skidding and helping them stop when the brakes are applied. We also need friction to make a fire.
Without friction between the shoes and the ground, you cannot walk properly. If there is no friction, all of us would be sliding around without any control over ourselves. While walking, you're pushing your foot back as you try to step forward. Friction holds your shoe to the ground so you can walk around.
Theophrastus , Carl Linnaeus , Aristotle, charakan . Find the odd one
Answer:
Charakan
Explanation:
The odd one out would be Charakan.
Theophrastus, Carl Linnaeus, and Aristotle are all scientists that contributed to the science of classification of living organisms (taxonomy).
Aristotle was the first scientist to classify living organisms into plant and animal kingdoms based on the artificial system of classification.
Theophrastus was a student of Aristotle and he wrote a book, De Historia Plantarum, classifying about 480 plants.
Carl Linnaeus invented the binomial system of naming living organisms in which organisms are given two names - the species and the genus name.
Charakan has no known contribution to taxonomy. Hence, the name is the only odd one.
