B.) cooled slowly
C.) found deep underground
D.) different easily observed minerals
Answer:
fine texture
Explanation:
did it on edge
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

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.
Therefore, 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.

Martin has a very low tolerance for alcohol- two beers and he's falling down drunk. this is likely at least partly linked to a small amount of which organelle in his cells? a) smooth endoplasmic reticulum b) lysosomes c) mitochondria d) rough endoplasmic reticulum e) Golgi apparatus
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 molecule has the lowest potential chemical energy?
Answer:
i have the same question too?
Explanation:
Chemical potential energy is defined as the energy present or stored in the chemical bonds of a substance. The decreasing order of the molecules with chemical potential energy is solid, liquid, and gas.
The correct answer is:
Option B. Carbon dioxide
The chemical potential energy can be explained as:
1. ATP and NADH are the energy currency of the cells, such that these molecules yield energy when the bonds are broken down.
2. Glucose is a solid compound that will have a high chemical potential energy as compared to carbon dioxide.
3. Carbon dioxide is a gaseous compound that will have the least chemical potential energy as compared to ATP, NADH, and glucose.
Thus, carbon dioxide will have the least potential chemical energy.

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.

_________
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.

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.

Which of these organisms does NOT produce an enterotoxin?
a. Shigella spp.
b. Clostridium botulinum.
c. Vibrio cholerae.
d. Staphylococcus aureus.
Answer:
b. Clostridium botulinum.
Explanation:
The enterotoxins (also know as exotoxins when they are produced by bacteria) are polypeptides secreted by microorganisms that target the intestine. These toxins may produce serious damage to the host by disrupting the function of the epithelial intestinal cells Moreover, Clostridium botulinum is a Gram-positive bacterium that is able to produce a potent neurotoxin (botulinum) which is known to cause severe flaccid paralytic deformities in humans.
The organism that does NOT produce an enterotoxin among the options given is b) Clostridium botulinum. Clostridium botulinum is a bacterium known for producing botulinum toxin, which is a neurotoxin rather than an enterotoxin. It does not, however, create an enterotoxin.
The severe sickness known as botulism is brought on by the botulinum toxin, which predominantly affects the nervous system.
Although enterotoxins can induce diarrheal disorders and are linked to gastrointestinal symptoms, an organism need not produce an enterotoxin to be pathogenic. The host's sensitivity to infection and the infectious dosage are other important variables.
