How do scientists think Prokaryotic Cells contributed to changing Earth’s atmosphere to include more oxygen?
Explanation:
Then, about 2.5 billion years ago, oxygen started getting added to the atmosphere by photosynthetic cyanobacteria. “Oxygen is produced as a waste product of photosynthesis. ... “The production and burial of plant matter over long periods causes oxygen levels to rise,” explains Poulsen

The digestive system, the circulatory system, and the muscular system work together and process and obtain nutrients from food. The skeletal system, the endocrine system, and the lymphatic system also work with the digestive system and process those nutrients.
Explanation:
The offspring in binary fission are
identical
different
Answer:
Identical
Explanation:
Binary fission is a form of asexual reproduction. This is when only one parent is involved in creating offspring. Since there is only one parent, two sets of DNA cannot be combined into a new offspring; so, it must be identical.

When the particles are equally spaced apart they have reached:
A. Hypertonicity
B. Dynamic Equilibrium
C. Homeostasis
D. Osmolarity
Answer:
B. Dynamic Equilibrium
Explanation:
Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium". The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, the movement of molecules does not stop.
Answer:
B. Dynamic Equilibrium
Explanation:
When the particles are equally spaced apart they have reached the dynamic Equilibrium.

Explain why DNA Sequencing proves that all species have a common ancestor
Answer:
Below
Explanation:
The reason why we can conclude that all species have common ancerstory is that all the species have several same base pairs. Here are a few listed:
A-G-G-C
As well as this later on:
C-C-A-A-C-C
Because this strand of DNA has several common base pairs, we can conldude that the species have common ancestory that made it this way.
Hope this helps!

Multicellular eukaryotes that live all over the planet and consume food. ______________________ [Text Wrapping Break] d. Unicellular prokaryotes that live in volcanic ash. __________________________[Text Wrapping Break] e. Multicellular eukaryotes that have cell walls and are heterotrophic. _______________________[Text Wrapping Break] f. Multicellular eukaryotes that have cell walls and are autotrophic. ________________________
Answer:
A. Unicellular prokaryotes that live in dust. Monera.
B. Unicellular eukaryotes that line in pond water. Protist.
C. Multicellular eukaryotes that live all over the planet and consume food. Animals.
D. Unicellular prokaryotes that live in volcanic ash. Monera.
E. Multicellular eukaryotes that have cell walls and are heterotrophic. Fungi.
F. Multicellular eukaryotes that have cell walls and are autotrophic. Plants.
Explanation:
The 5 kingdoms are a way of classifying all living organisms on our planet, as each species inside a kingdom shares similarities with the other species in it.
Monera kingdom includes all of the prokaryotic organisms that exist, which includes bacteria and archaea. These beings are characterized by lacking a nucleus and membrane-bound organelles and having one single circular chromosome that is found in the center of the cell. They are unicellular. Example: escherichia coli.
Protists are the most primitive eukaryotes that exist, most of them are unicellular and microscopic, but possess a nucleus and specialized organelles like the rest of the eukaryotes have. Example: yeasts.
Fungi and Plants are quite similar, they are multicellular eukaryotes that have cell walls. Their main difference relies on the way they obtain nutrients: fungi are heterotrophs, they feed off living things; plants, however, are autotrophs and realize photosynthesis (they do not need to feed). Fungi and Plants also reproduce differently: fungi reproduce through spores; plants can reproduce sexually or asexually. Fungi example: amanita; plant example: cactus.
Animals are multicellular eukaryotic organisms that reproduce sexually and are heterotrophs (some feed off plants, some feed off other animals). They are characterized by their ability to move. Example: horse.
Which organ releases the hormone insulin in order to regulate the level of blood sugar in the body?
Gall Bladder
Liver
b. Pancreas
d. Spleen
Answer:
Pancreas
Explanation:
Insulin is an essential hormone produced by the pancreas.
Answer:
Pancreas
Explanation:
During digestion, your pancreas makes pancreatic juices called enzymes. These enzymes break down sugars, fats, and starches. Your pancreas also helps your digestive system by making hormones. These are chemical messengers that travel through your blood.

Answer:
Explanation:
A diagram of a Punnett Square showing the chromosomes involved in the inheritance of sex-linked traits.
The female had the genotype XHXh, and produced the two gametes seen at the left side of the diagram.
The male had the genotype XHY0, and produced the two gametes seen at the right side of the diagram.
The genotypes seen in the center of the square represent the possible genotypes of the F1 generation.
Two female offspring are produced for every two male offspring.
One male and one female offspring inherit normal genes.
One female is heterozygous for the hemophilia trait and is considered a carrier.
One male receives a damaged X-chromosome and inherits the condition known as hemophilia.

Use Darwin's theory of Natural Selection to explain the process by which the four-legged land animal, A, may have evolved, over about 20 million years, from the fish-like creature, C, in the swampy conditions of the time.
Answer:
Due to environmental conditions.
Explanation:
With the passage of time, environmental conditions change which causes the evolution of of four legged land animals from fish like creature. This change occurs due to change in environment. In water, there is no need for legs because fish moves with the help of fins and tail but the organisms that lives on land has legs in order to move from one place to another so we can say that change in the physical structure of organism occurs due to environment.
