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
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
Coat color in horses is an example of which type of inheritance?
(1 point)
A. polygenic inheritance
B. dominant inheritance
C. Mendelian inheritance
D. recessive inheritance
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
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:
In fission (or binary fission), a parent separates into two or more individuals of about equal size. This type of reproduction is common among single-celled organisms including bacteria, archaea, and unicellular eukaryotes, such as protists and some fungi.

Explanation:
A student claims that the only difference between prokaryotic cells and eukaryotic cells is that
eukaryotic cells have a nucleus, but prokaryotic cells do not. What is wrong with this claim?
The description of the cell types is incorrect.
Prokaryotic cells have a nucleus, and eukaryotic cells do not.
The description of the cell types is incorrect. Both prokaryotic and eukaryotic cells have a nucleus.
There is another difference between the cell types. Eukaryotic cells have membrane-bound organelles, but
prokaryotic cells do not.
There is another difference between the cell types. Eukaryotic cells have a cell membrane, but prokaryotic
cells have a cell wall instead.
Explanation:
Eukaryotic cells:
• There is a well defined nucleus
• They are membrane bounded cell organelles like chloroplast, golgi bodies, mitochondria.
Prokaryotic cells:
• The nucleus are not well defined
• Cell organelles are not bounded by membrane
