Stromatolites contributed oxygen to the early atmosphere through photosynthesis.
What are stromatolites ?Stromatolites are layered sedimentary formations that are created mainly by photosynthetic microorganisms such as cyanobacteria, sulfate-reducing bacteria, etc. that lives today in a wide range of environments ranging from the shallow shelf to lakes, rivers, and even soils.
Cyanobacteria were ultimately responsible for one of the most important global changes that the Earth has undergone. Being photosynthetic, cyanobacteria produce oxygen as a by-product.

How do the plants depend on the animals for their survival give three examples
PLEASE HELP!!!!!!!!!!
Answer:
Plants provide animals with habitat and produce oxygen, which the animals use to survive. Animals decompose and become natural fertilizer plants until they pass. Animals provide fertilizer, pollinate plants, and disperse seeds. Plants are also beneficial for animal homes since many species live in close proximity to plants.
Explanation:
Answer:
Plants depend on animals because most of them decompose other dead non living things into our soil. They give animals air and to humans as well.
They also depend on each other for food.
They depend on each other for shelter. For example an insect uses a tree branch as shelter and protects it in return to the tree branch.

what is the difference between plant cell and animal cell
Answer:
Major structural differences between a plant and an animal cell include: Plant cells have a cell wall, but animal cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not.
Explanation:
Hope that helps :)
Answer:
A plant cell contains a singular vacuole In contrast, animal cells have many smaller vacuoles.
Explanation:
Plant cells have a cell wall, as well as a cell membrane. Animal cells have a cell membrane, but no cell wall.
Earlier, you read how a bedroom could be used to help someone make a connection to a cell maintaining homeostasis. The door to the room was compared with the cell membrane, and the trash can was said to be like the vacuole that stores wastes in the cell, helping you understand the functions of these organelles.
Now, think of another object that could be compared with a cell. Using the space below, be creative as you explain how cellular respiration, diffusion, and waste removal take place in both the cell and the thing to which you are comparing it.
Answer:
Explanation:
years ago. Homeostasis ensures that cells can obtain and use energy, make new cells, . biology biology active answer key chapter 5 5 reading work homeostasis and cell.
Another object that could be compared with a cell is a Car. cellular respiration, diffusion, and waste removal take place in both the cell and the car.
A car can be compared to a cell in the following ways:The metal body of a car maintains its shape even at high speeds. In terms of structure, its body is similar to a cell wall. In that they protect the interior of the car from intruders such as insects and dirt, the windshield and windows are analogous to plasma membranes. Cars require power to drive, which is generated when fuel is converted to energy in the engine, much how mitochondria produce ATP. The endoplasmic reticulum aids in material transport in cells, and the fuel line transports fuel from the gas tank to the engine in automobiles. The nucleus of a cell is analogous to the driver of a car. If the driver does not press the gas pedal, the automobile will not move.The gas pedal communicates the driver's intention to proceed to the engine, exactly as a ribosome does with information from the nucleus. When a car's engine burns fuel, it produces exhaust, which is passed through a catalytic converter before exiting the vehicle to reduce pollution. The Golgi apparatus, like the catalytic converter, does its own material packaging for transportation. Like vacuoles in cells, the automobile trunk and glove box serve as storage chambers.hence this is how a car is similar to a cell

A 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece. How large will the cell appear to the microscope user?
Answer:
A 10x Eyepiece magnifies 10 times; in other words, an object viewed through the eyepiece, in focus, will seem ten times larger than normal. ... In this case, a 10x Eyepiece and a 10x Objective Lens would combine to show a 100x image, or an image 100 times the actual size.
Explanation:
If a 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece, the cell will appear 100 times bigger than normal to the microscope user.
Magnification is defined as the ratio of the image distance to the object distance.
Magnification determines the number of times an image is larger or smaller than the object.
If the magnification is greater than 1, it means that the image is enlarged but if the magnification is less than 1, the image is a diminished image.
According to the question, if a 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece, the total magnification will be:
M = Mo × Me
M = 10 × 10
M = 100
This shows that if a 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece, the cell will appear 100 times bigger than normal to the microscope user.

i need the answer to the last question
Answer: 3. Structure is a better indicator of a relationship between two organisms because function can be caused by environment, not common ancestry. Structure is better than function because the structure is based on genetics. For example, the wings on a fly and the wings on a bird perform the same function, but their genetic bases are different. However, the wings on a bird and the arms on a primate are coded by similar genes even though the functions are different.
The best measure of relatedness is the underlying genomic DNA.
Explanation:
what is the relationship between transpiration and stomata
Answer:
Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.

in recent years much of califorinia has had drought conditions much of our food comes from califorinia and there are many growing cities in that state what do you think has happened to the ground water supply as droughts have occured there explain how a diversion system could be useful califorinia including the parts of such a system
Answer:
The level of ground water decreases.
Explanation:
Due to drought condition, the level of ground water decreases because of pumping of water for the irrigation purpose. Huge amount of water is required to irrigate a large area of California and in the drought conditions ground water is the only solution for this problem. The diversion system will be useful California by diverging river into these drought affected areas in order to fulfill the need of water for growing crops so we can conclude that this diversion system helps to fulfill the necessity of water during drought situation.
In Mendel's experiments, a trait that disappeared in the F1 generation but reappeared in the F2 generation was always a
Answer: A trait that disappeared in the F1 generation but reappeared in the F2 generation was always a RECESSIVE TRAIT.
Explanation:
The basic laws of genetics were laid down by an Australian monk in 1866, Gregor Mendel. From the results of his experiment, Mendel came to certain conclusions which are referred to as the Mendel's Laws of Heredity one of which includes the Law of Segregation of genes.
The Law of Segregation states that:
--> the hereditary characters of an organism are determined by genes
--> a gene for a character may have alternative forms ( alleles) which express the character in different ways;
--> if a diploid organism has two different alleles ( heterozygous) for a character, one allele may be dominant, dictating the expression of the character to the complete exclusion of the other ( the recessive allele).
Furthermore, Mendel's experiments can be proven by the study of a single- factor inheritance pattern. This is achieved by crossing a pure stock of white- flowered pea plants and red - flowered ones. The offspring of this cross are all red flowered pea plants. They form the F1 GENERATION.
Since only red flower colour is seen in the F1 generation, we say the the red flower form of the character is dominant. White colour, which does not show up in the F1 generation, but reappear in F2 GENERATION when F1 GENERATION is crossed, is said to be the recessive form of the character.
Therefore, this implies that the recessive traits can skip a generation to appear in future generations according to Mendel's experiments.
Answer: Yea it was Recessive.

How is phylogeny related to classification?
Answer:
Most modern systems of classification are based on evolutionary relationships among organisms – that is, on the organisms' phylogeny. Classification systems based on phylogeny organize species or other groups in ways that reflect our understanding of how they evolved from their common ancestors.

A. The rabbit's speed is increasing through time.
B. The rabbit is moving at a constant speed.
C. The rabbit's position is not changing through time.
D. The rabbit's speed is decreasing through time.
Answer:A
Explanation:
its is
The rabbit's speed is increasing over time, and it is known as velocity. Therefore, option A is correct.
What is velocity?Velocity is a term used in physics to describe the speed of an object in a particular direction. It is a vector quantity, which means it has both magnitude (speed) and direction.
The formula for calculating velocity is:
Velocity = displacement/time
In other words, velocity is often used interchangeably with speed, which is also a measure of how fast something is moving. However, velocity specifically refers to the speed of an object in a particular direction, whereas speed does not take direction into account.
Thus, The statement which is true about the rabbit's motion is "the rabbit's speed is increasing over time". Therefore, option A is correct.
