Place the following materials in the order in which they are likely to fossilize. Begin with the material that is most likely to fossilize, and finish with the material least likely to fossilize.
1. mammal teeth
2. bones of an adult mammal quickly buried
3. bones of an adult mammal left on the surface
4. soft body parts of any animal
Answer: correct order--->
1)mammal teeth
2.)bones of an adult mammal quickly buried
3.) bones of an adult mammal left on the surface
4.)soft body parts of any animals
Explanation:
Fossilization is the ability of an organism to be preserved and remain unaltered for a very long time. Through research , it has been found out that Harder parts of the body tend to remain preserved for a long time because they naturally have minerals deposited in them and may only be reduced, but the softer part or tissues do not get preserved for a long time because being made up of polymer can be disintegrated easily by natural biological and physical processes.
The order of which material will likely fossilize is
1.)mammal teeth
2.)bones of an adult mammal quickly buried
3.) bones of an adult mammal left on the surface
4.)soft body parts of any animals
Reason,
--Teeth and bones biologically contain calcium but the teeth is more tougher and durable than the bone, Even when a body is decomposed, the teeth most times are not affected at all.
Bones of an adult mammal left on the surface will decompose faster than the one buried because of the biological (natural decomposing ) and physical processes(temperature, wind, sunglight, rainfall ) which will both act on it at the same time because of its exposure.
- soft body parts of any animals will decompose fastest as bacteria will feed on it immediately since it lacks minerals that can elongate preservation.

Answer:
The Middle Latitudes have cyclones and anticyclones
Explanation:
The Middle Latitude is a spatial region of the earth which are found between the tropics and the polar circles.

A change in the environment is a(n)
A. instinctive, learned
B. internal stimulus, external stimulus
C. chemical signal, display
D. association, condition
Answer:
I believe is C. I might be wrong
Explanation:
¯\_(ツ)_/¯
A change in an organism's body is an internal stimulus, while a change in the environment is an external stimulus. Thus, the correct option is B.
What is the Environment?An environment may be defined as anything which is present in the surrounding of living entities through which it interacts for various purposes.
There are a lot of alterations in the body of an organism with respect to time. Apart from organisms, a lot of changes have also occurred in an environment gradually and continuously.
Changes in the organism's body are internal so it is called internal stimulus, while alterations in the environment are externally made so they are called external stimulus.
Therefore, the correct option for this question is B.

Hello. You forgot to put the image that complements this question. The image is attached below:
Answer:
pulmonary arterioles
Explanation:
Pulmonary arterioles are small blood vessels located in the lung. They appear as branches of the major arteries and have the main function of releasing blood from capillaries, in addition to regulating blood flow and peripheral blood pressure in capillaries.
It is important to note that arterioles are very small in size, which facilitates their functions to be performed efficiently and quickly.

You palpate a soft, slightly tender mass in the right scrotum of an adult male. You attempt to reduce the size of the mass, and there is no change in the mass size. Your next assessment maneuver is to:________
a. use two fingers to attempt to reduce the mass.
b. palpate the left scrotum simultaneously.
c. lift the right testicle and then compare pain level.
d. transilluminate the mass
Answer:
d. transilluminate the mass
Explanation:
Sometimes, painless hard or tender mass develop in the scrotum of men and can cause testicular tumors.
After detecting a scrotal mass, to reduce the size of the mass, the next assessment required is to transilluminate the mass in which testicles will be appear opaque on transillumination. Transillumination of mass will help to detect the orientation of mass which can be treated further.
Hence, the correct answer is d. transilluminate the mass

why can animals move and plants can't?
Answer:
Plants make their own food from sunlight, water, and carbon dioxide (part of the air). Making food like that is slow, so if they moved around too quickly, they'd starve to death. So, though they do move, it's usually very slowly.
Animals get their food from plants or from other animals. Moving around is a way for them to get more food, not just to use it up. It's also a way to avoid getting eaten.
(Even plants which appear to "eat" food, such as a venus flytrap, are actually only getting vitamins and minerals that way, not extra energy.)
Distinguish between the 4 major modes of nutrition of prokaryotes and identify each modes energy source and carbon source as well as giving an example
The four major modes of nutrition in prokaryotes are photoautotrophic, chemoautotrophic, photoheterotrophic, and chemoheterotrophic. Their differences, energy source and carbon source are explained below:
WHAT ARE PROKARYOTES?
Prokaryotes are a group of organisms that do not have their genetic material enclosed in a membrane bound NUCLEUS. They include bacteria, archeae etc.METABOLISM IN PROKARYOTES:
All organisms, prokaryotes inclusive, need energy for their metabolic activities. They also need carbon. Hence, based on their carbon and energy source, prokaryotes can be:
Photoautotrophic: These are prokaryotic organisms that use carbon dioxide as their carbon source and light as their energy source. Example iscyanobacteria.
Chemoautotrophic: These are prokaryotic organisms that act on inorganic substances as energy source and use carbon dioxide as carbon source. Example is Nitrosomonas bacteria.Photoheterotrophic: These are prokaryotic organisms that use light as source of energy but obtain carbon from other organisms (organic sources). Examples are heliobacteria, sulfur bacteria.Chemoheterotrophic: These are prokaryotic organisms that act on inorganic substances as energy source but derive their carbon source from organic compounds (other organisms).Learn more: https://brainly.com/question/6103977

Question is incomplete, The complete question is as follows:
When a bacterium such as E. coli is shifted from a warmer growth temperature to a cooler growth temperature, it compensates by:
A) increasing its metabolic rate to generate more heat.
B) putting longer-chain fatty acids into its membranes.
C) putting more unsaturated fatty acids into its membranes.
D) shifting from aerobic to anaerobic metabolism.
E) synthesizing thicker membranes to insulate the cell.
Answer:
C) putting more unsaturated fatty acids into its membranes.
Explanation:
Bacteria has the ability to change the composition of fatty acid present in its cell membrane to compensate the change in temperature.
When bacterium E.Coli will shift from hight or warmer temperature to low or cooler temperature, it will put more unsaturated fatty acids into its membranes which will mintain the fluidity in the membrane.
Hence, the correct option is "C".

If bacteria transformed with a recombinant pUC18 plasmid produce white colonies when grown on plates containing ampicillin and Xgal, which of the following is least likely?
a. They produce β-lactamase that provides resistance to ampicillin.
b. They carry a vector that contains a DNA fragment inserted into the multiple cloning site.
c. They produce functional β-galactosidase that cleaves X-gal.
d. They carry a vector with a lacZ gene that has been disrupted and rendered nonfunctional.
e. They carry a vector with the bla gene used as the selectable marker.
Answer:
c. They produce functional β-galactosidase that cleaves X-gal.
Explanation:
β-galactosidase is an enzyme capable of catalyzing the enzymatic hydrolysis of β-galactosides into monosaccharides by hydrolyzing the β-glycosidic bond. On the other hand, X-gal is an analog of lactose composed of galactose, which is widely used in laboratories for the detection of β-galactosidase. In the presence of β-galactosidase, X-gal is hydrolyzed by cleaving its β-glycosidic bond, thereby confirming the presence of β-galactosidase.
