Chromosome
Answers
Answer:
- DNA is wrapped around nucleosomes and condensed into chromosomes.
- Proteins affect the traits and function of organisms.
Explanation:
Nucleosomes are the basic unit of compaction of DNA. Each nucleosome is composed of ~148 bp double-stranded DNA and an octamer of histone proteins, which include two molecules of each core histone: H2A, H2B, H3 and H4. Subsequently, nucleosomes are packaged into chromatin fibers so they can be densely compacted into chromosomes. On the other hand, proteins are molecules that play important (structural and enzymatic) functions in a cell. These proteins may affect the structure/function of a cell, thereby affecting a certain characteristic/trait to develop.

97 percent
Explanation:
Science
Answer:

Explanation:
Over 97 percent of the earth's water is found in the oceans as salt water. Two percent of the earth's water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth's water available to us for our daily water supply needs.
what did humans evolve from I am creating a a evolution chain I know this can be considered a unintelligent question I am just not positive on what we evolved from
Answers
Answer: Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed biologically, we humans are Hono Sapines, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Human evolution is not linear manner it is a web, in the process of evolution primates lead to the emergence of homo-sapiens, which is distinct from the hominid family.
How did humans evolve?Human evolution is observed in a web manner not linear in evolutionary history primates lead to the homo-sapiens which is distinct from another family of hominids.
The hominid family includes great apes that diverged from the gibbons 15-20 million years ago. Evolution involves some studies, genetic studies, and h behavioral studies.
Anatomically it is observed in Africa 300000 years ago humans appeared, these studies were observed anatomically as the origin of humans.
Therefore human evolution is observed in a web manner not linear.

Horses have three basic coat colors: red (or chestnut), bay, and black. All the colors are controlled by the interaction of two genes, Extension (E) and Agouti (A). The following combinations produce bay color: EE/Aa, Ee/Aa, EE/AA, Ee/AA. Only two produce black color: EE/aa, Ea/aa. Other combinations of the alleles of these genes plus mutations of others result in many possible coat colors and patterns in horses

A. polygenic inheritance
B. dominant inheritance
C. Mendelian inheritance
D. recessive inheritance
Answers
Answer:
A. Polygenic inheritance
Explanation:
When the qualities or the attributes are passed from the parent to their progeny is called inheritance. It can be passed either sexually or asexually.
The correct answer is:
Option A. Polygenic inheritance
This can be explained as:
When a trait is regulated by two or more genes is called polygenic inheritance.Dominant inheritance occurs when the qualities from the parent possessing the dominant gene pass to the progeny.According to Mendelian inheritance paired genes assorts independently and are passed from parent to their progenies.Therefore, coat colour in horses is an example of polygenic inheritance.

Which of the following are parts of a bacterial cell?
Select all that apply.
mitochondria
flagella
cell wall
pili
Answers
Answer:
It is a gel-like matrix composed of water, enzymes, nutrients, wastes, and gases and contains cell structures such as ribosomes, a chromosome, and plasmids. The cell envelope encases the cytoplasm and all its components. Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus.
Explanation:
Flagella, cell wall, and pili are parts of a bacterial cell.
What is a bacterial cell?Microscopically small, single-celled creatures known as bacteria are found in millions in every habitat, both within and outside of other living things.
Some bacteria are hazardous, but most serve a helpful role. They are employed in industrial and medical procedures and sustain a wide variety of living forms, including both plant and animal life.
Around 4 billion years ago, bacteria are assumed to be the initial lifeforms to emerge on the planet. The earliest fossilized creatures are bacteria-like ones. Most biological and some materials can be used as food by bacteria, and certain strains can withstand harsh environments.
New insights into the functions of the gut microbiome are being provided by this expanding interest in how microorganisms affect human health. Bacteria are prokaryotes that do not contain any membrane-bound organelles.
Therefore, flagella, cell wall, and pili are parts of the bacterial cell.

Answer:
Jdjdjdj
Explanation:
Animals survive in deserts by living underground or resting in burrows during the heat of the day. Some creatures get the moisture they need from their food, so they don't need to drink much water, if any. Others live along the edges of deserts, where there are more plants and shelter.
Even though deserts don't get much rain, the desert is a habitat for some plants and animals. Each species has adapted to be able to live in a range of temperatures and without much water. ... Animals that live in deserts include lizards, geckos, toads, jackrabbits, camels, snakes, spiders and meerkats.

Explain how a school bus uses all of these energy types.
-Mechanical
-Chemical
-Electrical
-Thermal
Answers
Answer:
Mechanical
94 percent of all school buses in America are powered by diesel engines because of their reliability, durability and safety. Almost half of these (46 percent) rely on the cleanest, near-zero emission diesel engine technology.
Chemical
school bus uses petroleum as chemical potential energy.
Electrical
An electric bus draws electricity from the power grid and stores it in a battery that can be recharged once the electricity has been used up. This basically mirrors the way our electronics work. We plug them in and let the battery charge and then use them wirelessly until it's time to charge again
Thermal
They heat the cold coolant from engine's block to 160° F in as little as one hour, then pump it back to the vehicle's engine and heat exchangers. The result: engine is preheated and the vehicle's heat exchangers distribute an abundance of heat to the vehicle's interior.
