Answer:
At first, the Earth was not even able to support life. There was no oxygen in the atmosphere, and Earth's surface was extremely hot. Slowly, over millions of years, the Earth changed so that plants and animals could begin to grow. Living things then changed the Earth even more.
What does DNA have to do with variation of a species?
Answer:
dna affects the physical appearence and also how our body works. changes in our dna can cause one to look different and have different functions from what a normal organism of that species has. as that organism with a mutation reproduces, its offspring will end up having similar features causing a variation in the species
Explanation:
A lack of CO2 in the flask would have caused reduced O2 production. If O2 , ATP, and NADPH are the by-products of the light-dependent phase of photosynthesis, how does a lack of CO2 cause reduced O2 production
Answer:
Carbondioxide is a reactant of photosynthesis.
Explanation:
Carbondioxide is a reactant of the process of photosynthesis and the product of photosynthesis is oxygen, if there is no or less carbondioxide the rate of photosynthesis decreases which leads to the lower production of oxygen. The rate of photosynthesis affected by the reactants available to it. If Carbondioxide is available in large amount more photosynthesis occurs that leads to more production of glucose as well as oxygen. So we can conclude that lack of Carbondioxide results in lower production of oxygen in the process of photosynthesis.
Define el consepto de fraccion
Answer:
The concept of fraction
Explanation:
What is the concept of fraction tho? Fractions are numbers that represent a part of the whole. When an object or a group of objects is divided into equal parts, then each individual part is a fraction. ... It is divided into a numerator and denominator where the denominator represents the total number of equal parts into which the whole is divided.
A fraction represents the number of parts that we take from a unit that is divided into equal parts. It is represented by two numbers separated by a fraction line.

If the moon started its orbit from a spot exactly between Earth and the sun it would return to almost the same spot ?
Answer:
After 29.5 days
Explanation:
Complete question
If the moon started its orbit from a spot exactly between Earth and the sun, then after how much time it would return to almost the same spot ?
Solution
New moon occurs once in 30 days. Hence there is a gap of 30 days between two new moons. To be specific moon phases repeat after every 29.5 days. However, as per the Gregorian calendar there can be two new moon in one month with a gap of 15 days only between two new moons.
Describe an example of a plant responding to environmental stimuli
Answer:
Plants also detect and respond to the daily cycle of light and darkness. For example, some plants open their leaves during the day to collect sunlight and then close their leaves at night to prevent water loss. Environmental stimuli that indicate changing seasons trigger other responses.

What’s the answer hurry it’s a test ?
Answer:
A: maintains genetic continuity from one generation to the next
Explanation:
I think A is correct because it mains genetic continuity from one generation of cells to the next. So all you cells in skin that are dead are replaced by the exact replica of next skin cells that arose from mitosis.
Gametes undergo meiosis and not mitosis.

An ecological footprint A) is a means of determining increases in populations that lived in the past. B) is a means of understanding resource availability and usage. C) measures dispersion and adaptability. D) will estimate population movements.
Answer: An ecological footprint is a means of understanding resource availability and usage. The correct option is B.
Explanation:
The ecological footprint is a method which is used to measure the rate as which humans use natural resources in their environment and generate waste from them compared with how fast nature can absorb these wastes and generate the used resources again. The productive areas which are measured through this means are:
--> cropland,
--> grazing land,
--> fishing grounds,
--> built-up land,
--> forest area, and carbon demand on land.
The importance of ecological footprint to the environment should no the over emphasizes. When properly observed, different environmental pollution would be dealt with. Generally, there would be:
--> decreased desertification,
--> decreased global warming
--> availability of fresh unpolluted air and
--> decreased carbon emissions.
why is the cell cycle often represented as a circle
Explanation:
The cell cycle is a cycle, rather than a linear pathway, because at the end of each go-round, the two daughter cells can start the exact same process over again from the beginning.

How can extinctions and expansions occur in the same habitat? Explain your answer.
When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time.
Extinctions are associated with biodiversity changes, thereby affecting species expansion.
What is extinction?Extinction refers to the disappearance of a given taxonomic group (e.g. species-level extinction).
This process of disappearance (extinction) modifies the trophic relationships in the ecosystem.The modification may lead to the expansion of a given species (e.g., prey in the case of predator extinction).In conclusion, extinctions are associated with biodiversity changes, thereby affecting species expansion.

The creation of genetically identical offspring by a single parent, without the participation of sperm and egg, is called The creation of genetically identical offspring by a single parent, without the participation of sperm and egg, is called spontaneous generation. asexual reproduction. regeneration. sexual reproduction.
Answer:
Asexual reproduction.
Explanation:
The generation of genetically identical offspring from a single parent, without the fusion of sperm and egg, is called asexual reproduction. Asexual reproduction occurs when there is only one parent from which organism is produced. Budding, binary fission and fragmentation are the different types of asexual reproduction that involves only one parent and no fusion of sperm and egg cells.

When modeling fisheries: (You may choose one or more answers)
A. Fixed quota models result in multiple maximum sustainable yield population levels
B. Fixed effort models result in an inability to harvest at maximum sustainable yield
C. Fixed quota models are risky because slight miscalculations can result in fish population extinction
D .Fixed effort harvesting reduces the risk of population extinction
Answer:
Option A, Fixed quota models are risky because slight miscalculations can result in fish population extinction
Explanation:
Some of the major drawbacks of modelling fishing are as follows –
a) The fixed quota model is very risky as a miniscule change in attributes can result into extinction of fish.
b) On the other hand fixed effort harvesting can decrease the risk of fish population extinction
Hence, option A is correct
Describe one property of water, and explain how the structure of water is responsible for this property. WILL MARK BRAINLIEST!!
Answer:
Water has cohesive and adhesive properties.
Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.

During a section of the cell cycle collectively called ______, the cell is not dividing, but protein synthesis, cell growth, DNA replication, and basic cell functions are occurring.
Answer:
INTERPHASE
Explanation:
The cell cycle refers to the series of event from DNA replication to actual division of a cell. Mitosis and meiosis are the two types of cell division, which is made up of two stages namely: interphase and the M-phase.
The interphase is also called resting stage because the cell is not undergoing any division. The interphase is further divided into G1, S and G2 phases. In these stages, the events that occurs include; protein synthesis, cell growth, DNA replication, and basic cell functions.
