In an investigation designed to determine the effect of the amount of water on plant growth, two groups of equal-sized bean plants of the same species were grown under identical conditions, except for the amount of wafer they were given. One group was watered with 200 milliliters of water once a day, while the other group was watered with 400 milliliters of wafer once a day. After several days, the heights of the plants were measured. It was determined that the plants watered with 400 milliliters of water once a day showed more growth. The independent variable in this investigation is the
A. type of bean plants used in the experiment
B. amount of water given to the plants each day
C. type of soil the bean plants were growing in
D. group of bean plants watered with 200 mL of water

Selectively permeable membranes are important in cell function. What makes a membrane selectively
permeable?
A
The ability to remove bacteria from the cell.
B The ability to use energy to make proteins used in the cell.
The ability to modify, sort and package proteins and lipids for storage or
C
transport out of the cell.
The ability to allow needed materials to enter and wastes to exit as well as the ability to block
unneeded materials from entering the cell.
D
Answer:
The ability to allow needed materials to enter and wastes to exit as well as the ability to block unneeded materials from entering the cell.
Explanation:
A selectively permeable cell membrane only allows some things to go through it, therefore this answer choice is the correct one because it is explaining how it is selectively permeable.
Orange trees planted in a grove or orchard would most likely fall in which category of population distribution?
a.even
b.random
c.clumped
d. density
Answer:
A) Even
Explanation:
got it right on edge :)
Orange trees planted in a grove or orchard would most likely fall in the even category of population distribution. The correct option is a.
What is population distribution?Population distribution is how the population of something, plants, animals, or humans is distributed in specific areas. It specifies where people live or where they are not living.
There are three types of population distribution:
Uniform dispersion - In this distribution, the population is uniformly or evenly distributed in the areas. Even distribution comes under this distribution.Random dispersion - there are no predictable patterns in this dispersion. They are randomly present anywhere.Clumped dispersion - This distribution shows the bunch or group of population is areas then there is no population, and then there is a a bunch of population in another place.Thus, the correct option is a. even.

Why do scientists use scientific names to describe organisms?
HElp me to get brainless
Answer:
B
Explanation:
Experiment tools and methods were not as precise as they are now. Since tech has evolved so has the ways to look at atoms meaning that they will see new and different things.
This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of their experiments were a surprise and they did not fit with the existing model. Scientists changed the model so that it could explain the new evidence. And Because more experiments gave more data, theories and models for atoms changed to be more accurate over time.

A team of engineers is designing a new ship. The engineers first build several models of the ship. Explain in your own words why the models could help the engineers
Answer:
The model could help the engineers by giving they a prototype to build off of so they have an idea of what they ship looks like, and if the test it, they could troubleshoot and see the errors/successes of the model.
Explanation:
The engineers first build several models of the ship as the model could help the engineers by providing them a prototype to build of so that they have an idea of what or how the ship will looks like, and if they test it, they could troubleshoot and see the errors or successes of the model of the ship.
What are the fields in which science is applied?Science has the factual based knowledge and it has about the Nature as well as the natural world that has created on the basis of observations and the experiments. It has the study of the experiments and observations and it has totally depend upon the scientific result that has obtained after the scientific experiments.
There are several fields in which science has been applied and these field are healthcare, telemarketing, environmental engineering, banking, government regulation, space, biochemistry, physics, chemistry, biochemistry and astronomy, engineering.
Therefore, The engineers first build several models of the ship as the model could help the engineers by providing them a prototype to build of so that they have an idea of what or how the ship will looks like, and if they test it, they could troubleshoot and see the errors or successes of the model of the ship.

Which of the processes offers the GREATEST evolutionary advantage of sexual versus asexual reproduction?
А
meiosis
B В
mitosis
С
budding
D
binary fission
Answer:a
Explanation:
The process that offers the GREATEST evolutionary advantage of sexual versus asexual reproduction is MEIOSIS.
Meiosis is a type of cell division that is used by organisms of sexual reproduction to produce haploid (n) gamete cells.Meiosis produces new genetic variation in offspring due to:
the random separation of alleles in gametes when chromosomes separate crossing-over or recombination which is the interchange of genetic material between non-sister chromatidsgametes randomly fuse to produce a diploid (2n) organismIn conclusion, the process that offers the GREATEST evolutionary advantage of sexual versus asexual reproduction is MEIOSIS because it is capable of introducing new alleles and increasing genetic variation in a population.

how does matter move from the hydrosphere into the biosphere explain in your own words
Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.
What is hydrosphere and biosphere?Hydrosphere:-
The hydrosphere is the collective mass of water which is found on under, or above the surface of earth. Although earth hydrosphere is 4 billions old. A planet's hydrosphere can be liquid, vapor or ice.
Biosphere:-
The region or area of surface where living organisms survive their life are called as biosphere. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to survive life.
Evaporation:-
The process in which water or liquid converts into vapor is called as evaporation. In the case of water it starts vaporization at 100 degree C.
So, we can say that the conversion of matter from hydrosphere to biosphere is successfully achieved by evaporation.
Therefore, Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

Which option describes a strong argument against the development of nuclear power? A nuclear power company is proposing a nuclear power plant near a quiet, small waterside town. The company is promoting this development by stating that nuclear power does not produce pollutants.
Answer:
The correct answer is B) The company is promoting this development by stating that nuclear power does not produce pollutants.
Explanation:
Whilst the process of power generation itself does not produce environmental pollutants like fossil fuels which features the emission of carbon monoxide when they are partially combusted, it does leave behind radioactive wastes, in the same way, combusted charcoal or wood leaves ash behind.
The challenge with radioactive wastes is that they are inimical to human health and can remain so for hundreds of centuries.

In a lab investigation, one group of students (group A) measures the speed of a .1 kg toy car to be 2.5 m/s at the bottom of a ramp. Another group of students (group B) measures the speed of a car to be 3 m/s at the bottom of a ramp. The car's starting position at the top of the ramp is 1 m high. What is the potential energy of the car at the beginning of the experiment before its speed is measured?
Answer:
i think you have to do 1k *2.5 m/s= 2.5
and
3m/s *1m = 3
and then you do 3-2.5

comparative dating
associative dating
virtual dating
relative dating
Answer:
relative dating
Explanation:
The fossils' age can be determined by using two methods: Absolute Dating and Relative Dating.
The "Relative Dating" examines the relationship between rocks and fossils in order to date certain objects. The correlation between things are checked according to the order of events in history and not according the the event's numerical age. The fossil record here is known as "index fossils." It becomes the basis for knowing the geologic period.
