cell theory establishes which of the following conclusions about cells?
A) all cells have the same size and shape
B) all cells form by free-cell formation
C) all cells are produced by other living cells
D) all cells have a cell wall
Answer:
C) all cells are produced by other living cells
Explanation:
Cell theory establishes the conclusion that " all cells are produced by other living cells". According to cell theory all the living cells are generated from pre- existing cells. Thus, option C is correct.
What is cell theory?Cell theory is a scientific theory given in nineteenth century and according to cell theory " cell is the structural and fundamental unit of life" and " every living cell is made up of pre existing cell".
The cells in multicellular organisms function differently from those in single-celled organism. A unicellular depends upon only one cell for all functions occurred in body. On the other hand a multicellular organism has cells specialized to perform several body functions that combinedly support the organism.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of levour is at the orgneele level on the other hand in multicellular the division of lavour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,Cell theory establishes the conclusion that " all cells are produced by other living cells". According to cell theory all the living cells are generated from pre- existing cells. Thus, option C is correct.

Water conservation is an important issue for many reasons. One factor is that water conservation preserves and protects our natural resources. Conserving water means more water is available to serve additional water needs, as well as for wildlife and recreation. Water conservation practices can result in lower wastewater discharges which can mean an improvement in overall water quality. Conserving water diminishes our need to find or build new water sources, leaving them in reserve for our possible later use. Preservation does result in
A) lower algae levels
B) reduction in industry standards
C) slowing the building of new housing
D) lessening the need to find new water sources
Answer:
i believe the answer is D) lessening the need to find new water sources

Pet owners begin to abandon their Burmese pythons in the Everglades when they become too large for home care. Native species of frogs and reptiles decrease with the introduction of the snakes. What does this scenario represent?
Answer: This scenario represents predation.
Explanation:
Predators are the animals which kill and consume other animals or birds to sustain their lives.
Burmese pythons are predators which can kill frogs and other reptiles in Everglades. These can consume wild animals like mammals and birds. They can even kill and eat alligators.
These pythons if kept as a pet can harmful for their owners and must be get rid of them. According to this scenario the pythons being predators can eat native frogs and other reptiles thus will decrease the population of the frogs and reptile. Thus will disturb the natural balance.

Oil formation occurs where millions of years ago there were large oceans.this is because oceans have
A- waves that are constantly moving
B- great numbers of tiny marine animals
C-currents that mix the water throughly
D-deep caverns where no light can reach
Answer: A- waves that are constantly moving
Explanation:
Oil is formed from remains that settles in the ocean over the year,this remains are be acted upon by bacteria in the oceans to form hydrocarbons from where fossil fuel is formed in the ocean floor. This is possible because of the movements of waves in the ocean that allows for mixing of this remain and its movement to ocean floor.
how will a organism be benefited if it reproduces through spores
Answer:
Spore can survive under unfavorable conditions as they are covered by a hard protective coat. Spores can grow to produce new plants and does not require sexual interaction with another organism. Due to their small size and light weight, they can be dispersed easily.
Spores can remain dormant till favourable conditions become available. b. Spores help an organism to tide over the bad phase. Spores can be spread through water, air or animals and thus is good for the spread of an organism to more places.

B. CTT AGG
C. CTT ACC
D. CAA UGG
ISBN
Answer:
The correct answer is D. CAA UGG
Explanation:
According to the rule of base pairing the Adenine make complementary base pairing with thymine and thymine with adenine and guanine and cytosine base pairs with each other in DNA.
In RNA in place of thymine, uracil base pairs with the adenine. Therefore according to this base-pairing rule, the DNA strand GTT ACC will give rise to transcript CAA UGG. So in place of adenine uracil has come.
Therefore the correct answer to this question is D. D. CAA UGG

A, Different types or sizes of ammunition
B, Different granulation sizes of black powder
C, Different types of firing mechanisms
D, Different barrel types or lengths
Answer:
B, Different granulation sizes of black powder
Explanation:
A muzzleloader firearm is a firearm that has a muzzle through which the propeller and the projectile is loaded from. For muzzleloader firearms, Fg, FFg, FFFg and FFFFg are examples of Different granulation sizes of black powder. The number of F's represent how the black powder is grounded, FFFFg is the smoothest and is used for muzzleloading rifles of 45 caliber and smaller. FFG is less smooth and is used in muzzleloading rifles larger than 45 caliber while FG is the most coarse used in large bore shotguns.
