Answer:
This question lacks options, the options are:
A) symbiosis
B) ecosystem
C) community
D) population
E) biosphere
The answer is D) Population
Explanation:
Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.
This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.
This observation completes what a POPULATION is all about, hence, a population was observed.
Answer:
1) start as a carbon molecule in the atmosphere
2) taken in by trees through photosynthesis
3) carbon is taken into decayed organism
4) then it is taken into dead organisms and waste products underground
5) millions of years later, it is stored in a fossil
6) fossil fuels used by factories then emit carbon dioxide back into the atmosphere (back to starting position
if you want the whole cycle then..
7) used again by a tree
8) released as organic carbon (some)
9) tree leaf is eaten by an animal, which then releases carbon either from respiration or when it dies
I don't know How incorrect answer how
Answer:
A
Explanation:
The correct answer would be that <u>the availability of food resources for black mice and brown mice will decrease.</u>
<em>Since the food requirements of the black mice are the same as that of the invasive brown mice, the available food supply that used to be only for the black mice would now be shared by the two strains of mice. Hence, the available food for the two groups of mice will naturally decrease.</em>
There is no sufficient information to conclude that the population of tan mice will decrease, hence, option B is incorrect.
The black mice and tan mice have different food requirements going by the information available in the illustration, hence, both cannot compete for food resources. Option C is, therefore, incorrect. In the same vein, option D is incorrect because the tan mice have different food requirements from the brown mice.
<u>The only correct option is A.</u>
Answer:
The correct answers are: Ribosome, Mitochondria, Chloroplast (in case of a plant cell).
Explanation:
- The Endo-membrane system in the cell represents the membranes of the Nucleus, Endoplasmic Reticulum, Golgi apparatus, Plasma Membrane, Vacuole and Lysosome.
- The Nuclear Envelope is made up of a phospholipid bilayer which remains in continuation with the ER (endoplasmic reticulum) membrane.
- Therefore, fluorescent tagged integral membrane protein localised in the outer nuclear envelope can move into the ER membrane by lateral movement or through vesicles that bud off from the membrane of the nuclear envelope and fuse with that of the ER membrane.
- Vesicles bud off from the membrane of the ER and fuse with the Golgi apparatus. Therefore, the fluorescent tagged integral membrane protein can move into the membrane of the Golgi apparatus.
- Vesicles bud off from the Golgi apparatus and fuse with the Plasma membrane, Lysosome membrane, and Vacuole membrane. Hence, the fluorescent tagged integral membrane protein can be found in all these organelles.
- Ribosome lacks a membrane and hence, the fluorescent tagged integral membrane protein will be absent over here.
- Both Mitochondria and Chloroplast, are self-replicating and dividing organelles. Their proteins (membrane or matrix) are encoded mostly by their own genome. Also, vesicles that bud from from nucleus or ER or Golgi apparatus do not fuse into their membrane. Hence, the fluorescent tagged protein would not be able to reach their membrane.
