Answer: Descriptive, Comparative and Experimental (which comes from experimentation).
Explanation:
There are three types of scientific investigations:
Descriptive: This type of scientific investigation studies parts of a system, which can be natural or artificial. It describes everything that is being studied and no predictions are made. There are three types of descriptive methods: case-study methods (an in-depth study is produced from many sources with different methods), observational methods (no questions asked, just an observation of the behavior of a subject and no manipulation of the variables), and survey method (some people are interviewed and the researchers study the answers.)Comparative: It gathers information from organisms, systems, places or from any source, to compare them using also a control group. But, there is no imposed treatment because it is not ethical or because it is not possible. So, the treatment is only observed.Experiment: As its names says, it uses an experimental test designed to study some phenomena, where variables are controlled so the treatment is not only observed as the comparative method. Then those variables are measured to collect information or evidence that supports or not a previous hypothesis and is used to assess theoretical knowledge. The independent variable is manipulated while the dependent variable is measured. This type of scientific investigation comes from experimentation.what is the relationship between gens , cromosomes, and DNA

1. A bacteria cell that divides to create two exact copies of itself is an
example of
A. sexual reproduction
B. homeostasis
c. asexual reproduction
D. DNA replication
Answer:
Asexual Reproduction
Explanation:
As the bacteria cell is dividing on its own to create more bacteria, it is performing asexual reproduction as it is not reproducing with a secondary bacteria cell.
Asexual reproduction is the process by which a bacteria cell that divides to create two exact copies of itself. Thus option C is correct.
What is bacterial cell division ?Bacteria reproduce by the process of asexual reproduction which is mainly binary fission, where the offspring produced from parent are similar.
In this process parent cell is undergo division and separated into two new daughter cells. Each daughter cell get one copy of its parent DNA.
No spindle apparatus formation occur in binary Fission. In this process, the DNA molecule undergo replication and attaches each copy to various parts of the cell membrane
For example, Prokaryotes like E. coli, Archaea and some eukaryotes like euglena reproduce through binary fission.
The advantage of binary fission is very fast and it requires single organism or parent.
Thus option C is correct.

Fine texture describes an extrusive rock. thus option A is correct
What is rock cycle ?Rocks are formed naturally and it is the non-living earth made by collection of mineral grains held together in a firm, it can be tiny or big as well and can be easily identified with their texture.
The Rock cycle is a continuous process through where old rocks are transformed into new rock by a process of cool down of molten magma, when it solidifies become igneous rock.
In a rock cycle, when the break down of these igneous rocks occur small particles that are transported and deposited to form sedimentary rocks, When the igneous and sedimentary rocks heated up and under the pressure they change into metamorphic rocks.
The metamorphic rocks which are subjected under great heat and pressure melt down to form molten magma which again can cool down and solidify into igneous rocks

A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because she did not believe the new formula helped plants grow better than the old formula. it was necessary to see data from more plants before the conclusion could be accepted. it was necessary to have tested the fertilizer on different kinds of plants. she thought he should test additional fertilizer formulas on the same two plants.

The use of energy and matter by living organisms
_________
Answer:
it involves chemical cycling from chemical energy from the sun to heat lost from the ecosystem :D
Explanation:
hope this helps, its different options on canvas (plz give brainliest
The use of energy and matter by living organisms involves chemical cycling from light energy from the sun and returning of chemicals to the cycle.
Photosynthesis is the process by which plants and algae use light energy from the sun, water (H2O), and carbon dioxide (CO2) in order to produce oxygen (O2) and energy in the form of simple carbohydrates (sugar).The overall chemical reactions in the photosynthetic process can be written as 6CO2 + 6H2O → C6H12O6 (glucose) + 6O2The biogeochemical cycles refer to the pathways by which essential compounds of living things are circulated.For example, the carbon cycle involves the exchange of carbon between biotic (organisms) and abiotic (environment) factors.During photosynthesis, plants absorb CO2 from the air to produce carbohydrates such as glucose, thereby decreasing the level of CO2 in the atmosphere.Plants in turn serve as food for herbivores.Finally, when herbivores dead, carbon-based compounds are broken down into simpler carbon compounds by decomposers (i.e. bacteria and fungi).In conclusion, the use of energy and matter by living organisms involves chemical cycling from light energy from the sun for the production of chemical energy in food to the decomposition and the returning of chemicals to the cycle.

in summer, what happens to the hurricane’s temperature, category, and speed as it travels across a body of water and then land?
I think it starts to get slower as soon as it starts traveling because then hurricanes wouldnt be as bad and would be long, and it could possible get worse as it travels across the water because it could be sucking up water so then it would get bigger and worse. The tempertaure will get colder because it will then start to pour and cause destruction and make it windy and very chilly.
In summer the temperature of hurricane will get colder because it will then start to pour and cause destruction and make it windy and very chilly and it could be sucking up water so then it would get bigger and worse.
What is hurricane?Hurricane has been defined as the conditions which has been expected in a specified area. As defined by National Oceanic and Atmospheric Administration (NOAA), it means that hurricane conditions (sustained winds of 74 mph or greater) are possible within your area and hurricane warnings means hurricane conditions are expected in an area.
The warm ocean water allows more water to get evaporate and this gives more power for the Hurricane to began. Powerful winds clash as a result of the air to move towards upwards which has light wind around the area allows it to start moving round and round with this whole process continues to make the Hurricane powerful and faster.

Answer:
is it okk
Explanation:
The lysosomes are the cellular organelles containing the hydrolytic enzymes which help in the metabolism of the complex and toxic compounds. The alcohol which is consumed is degraded and digested by the lysosomes which decrease the rate of digestion of the other complexes like the proteins. This decreased lysosomal activity leads to liver damage.

Which of the following substances is excreted by sweat glands in repense to the break down of proteins and the formation of ammonia?A) waterB) ureaC) lysozymesD) sebum
Answer:
The correct option is (b).
Explanation:
Due to high temperature and excessive motion, sweating is triggered. When Nitrogen based compounds breaks down, ammonia is produced. As ammonia is very much toxic for body, so its gets converted to urea. Urea is excreted by sweat glands. It also secretes sodium, water along with urea. Hence, the correct option is (B) "urea".
Urea is excreted by sweat glands in repense to the break down of proteins and the formation of ammonia.
Urea is one of the organic chemical components of urine that dissolves in alcohol and water and has the ability to crystallize.
Urea is produced when proteins are metabolized and elements that have nitrogen are degraded.The process that leads to the formation of this chemical compound is known as the urea cycle, animals that excrete amine nitrogen such as urea are classified as ureotelic.On the other hand, if the expulsion of amine nitrogen occurs as ammonia, the organisms are called ammonothelic.Therefore, we can conclude that urea is a substance that is formed in the body during the processing of proteins and nitrogen compounds in the liver.

The "calico" pattern of coat coloration in female cats is a result of:__________
a. fragile X syndrome
b. x chromosome inactivation
c. unequal crossing over
d. endoreduplication
e. Turner syndrome
Answer:
b. x chromosome inactivation
Explanation:
As you know, female cats have an x chromosome inherited from their mother and an x chromosome inherited from their father. After these two chromosomes are inherited and determine the sex of the cat, one of them will be disabled at some point in fetal development. Inside the X chromosome is the gene that determines the coat color of cats, when one of the two x chromosomes is deactivated, the other x chromosome will have all of its cells activated. In this case, if the activated chromosome is the one that has genes for the "cheetah" pattern of the coat color, all the descendants of this female cat also have the same coat.
