Answer:
Please find the explanation below
Explanation:
Primary succession is a type of succession that occurs in an area with no previous community. It usually contains bare rocks, which are grown upon by certain living organisms (biotic components) called PIONEER SPECIES. These organisms, which include lichens and mosses, colonize the bare rocks and contribute to the formation of soil by the gradual disintegration of the rock particles.
These biotic components (living organism) also help to enrich the soil being formed as they add organic matter, which serve as nutrients, when they die and decompose. The actions of these living organisms on the formation of soil enables other organisms to easily colonize the area.
Humans are able to move their shoulder 360 degrees. What morphological features aid in this degree of motion (i.e. which bones)? Examine the bat wing below. Is there the same degree of motion? Explain why or why not.
Answer:
This question is incomplete because of the absence of bat diagram discussed in the question
Explanation:
Humans body contains several joints that allows from movement of bones at some junctions called the "joints". Joints are points where two bones meet. Examples of the human joints include the ball and socket joints, hinge joint, pivot joint, gliding joint, saddle joint. The type of joint in the human shoulder that allows for 360 degrees rotation is the ball and socket joint. It involves a bone that has a round head like that of a "ball" which can fit into an open cup-like shape called the "socket", hence the reason for the name. This joint allows for movement in all directions.
The bat wing does not move at the same degrees (360°) as it does not move in all directions - the wing has an up and down movement which is more of a 180° movement and not a 360° movement.
Which statement best explains the relationship between producer and consumers in terms of
energy?
A. Consumer produce glucose that producer's use for energy B. Consumers convert carbon dioxide into energy
C. Consumers provide energy for producer to undergo aerobic respiration
D. Consumers convert glucose from producers into ATP
please only reply if you know the answer
Answer:
> Consumers convert glucose from producers into ATP.
Explanation:
Consumers do NOT provide oxygen or glucose for producers.
The statement, consumers convert the glucose from producers into ATP. So the correct option is D.
What are producers and consumers?In feeding chains, organisms are categorized into trophic levels. Producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers roughly correspond to these levels.
Autotrophs, another name for producers, grow their own food. Every food chain's first level is comprised of these. Plants or single-celled creatures represent the majority of autotrophs. The majority of autotrophs produce their "food" (a nutrient called glucose) from sunlight, carbon dioxide, and water through a process known as photosynthesis.
The most well-known form of autotroph is a plant, but there are numerous others as well. Algae are autotrophic, and their bigger forms are known as seaweed. Autotrophs include the small sea life known as phytoplankton. Autotrophic bacteria include certain varieties. For instance, microorganisms that live in volcanoes that are still active utilize sulfur compounds to make their own food. Chemosynthesis is the name of this process.
Therefore the correct option is D.

A sample of peptide of unknown sequence was treated with trypsin to produce the following smaller peptides:
1) Met-Val-Ser-Thr-Lys
2) Val-Ile-Trp-Thr-Leu-Met-Ile
3) Leu-Phe-Asn-Glu-Ser-Arg
Another sample of the same peptide was treated with chymotrypsin and gave the following smaller peptides:
1) Asn-Glu-Ser-Arg-Val-Ile-Trp
2) Thr-Leu-Met-Ile
3) Met-Val-Ser-Thr-Lys-Leu-Phe
What is the sequence of the original peptide?
Answer:
The sequence is >> Met-Val-Ser-Thr-Lys-Leu-Phe-Asn-Glu-Ser-Arg-Val-Ile-Trp-Thr-Leu-Met-Ile, or abbreviated M-V-S-T-K-L-F-N-E-S-R-V-I-W-T-L-M-I
Explanation:
Trypsin is a serine protease enzyme capable of hydrolyzing different types of proteins. This enzyme is used in biotechnology and molecular biology to hydrolyze at the carboxyl side of arginine or lysine residues. Moreover, chymotrypsin is another digestive protease that also catalyzes the breakdown of proteins into small polypeptide chains. This enzyme cuts the C-terminal side of aromatic amino acids such as tryptophan (W), tyrosine (Y) and phenylalanine (F) on peptide chains.

Color of Starch solution It was a whitish color. Dark, purple, black color. inside bag!Color of Iodine solution A golden color. A transparent creme inside beaker color. Color of starch solution White White inside bag! Color of H20 in beaker TransparentExplanation: Conclusion
The conclusion to this test is that the plastic bag is permeable to iodine. The result
of this experiment clearly answers the "Problem" as stated above. This is~ by
the fact that the starch solution (dependent variable) in the baggie turned purple,
indicating the presence of iodine (independent variable) in the mixture. The starch
solution is the dependent variable because its color is affected by the iodine
solution. M.y hypothesis was that the iodine will get into the bag of starch because
the baggie is permeable to iodine. If the iodine solution penetrates the bag, it will
turn the starch solution inside the baggie, purple. The control data chart above
shows that if the starch had not been immersed in the iodine solution, but rather a
water solution, it would have remained the same color, white. Obviously, in order
for the iodine to enter the starch solution, the baggie must be permeable to the
iodine. The baggie represents a cell membrane. This lab is meant to demonstrate
whether or not a cell membrane is permeable to substances. Cell membranes of
living organisms may be permeable to some substances, but not permeable to other
substances. In this experiment,'1..charted that the iodine solution in the beaker did
not turn purple. This means that the starch solution did not penetrate the baggie
and therefore did not mix with the iodine outside the baggie. Because of this data, it
is clear that the plastic baggie is not permeable to starch, but is permeable to iodine.
In a cell membrane, this is called selective permeability. In other words, the iodine
can go through the baggie, but the starch cannot. The purpose of this experiment is
to show that a cell membrane is a type of barrier, and is permeable to some
substances, but may not be permeable to all substances. Therefore, a cell membrane
is selectively permeable.

c. natural gas
d. cement production
Answer:
The answer is a. petroleum
Explanation:
I just took the test and got it right.
The leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.
What is Carbon emission?Carbon emission may be defined as the process of liberation of greenhouse gases like carbon dioxide and/or their precursors into the atmosphere over a specified area and period of time. These emissions are significantly contributing to climate change across the world.
When it comes to the global fossil carbon emissions in 2004, the major cause of that was due to petroleum. During that time, people utilize a large amount of petroleum in burning activities. This stimulates the rate of carbon emission in the entire atmosphere which is harmful to the health of living organisms.
Therefore, the leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.
