D. both
Show different life cycle patterns with the help of near labelled diagram
Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.

how the scientist evolve?
Your own word
Answer:
Evolution is a consequence of the interaction of four factors: (1) the potential for a species to increase in number, (2) the genetic variation of individuals in a species due to mutation and sexual reproduction
Explain how a symbiotic relationship like the one described in the endosymbiotic theory would have benefited each cell.
Answer:
cannot grow outside their host cell of biolapsy
The symbiotic relationship is a type of relationship in which two organisms living with each other and gives benefit to one another.
Mutualism is a type of symbiotic relationship in which both organisms benefited from one another. In this type of relationship, one organisms is smaller that lives inside the body of other big organisms.
For example, bacteria lives in the nodules of plant's root. The plant provides shelter to the bacteria while on the other hand, bacteria fixes atmosphere nitrogen into available form so in this way both get benefits from one another.

3. What is the kingdom that contains single-celled organisms that live in extreme environments?
A. plantae
B. bacteria
C. protista
D. archaea
The kingdom that contains single-celled organisms that live in extreme environments is archaea. The correct option is D.
What are single-celled organisms?A single cell makes up a unicellular creature, also referred to as a single-celled organism, as opposed to a multicellular organism, which is made up of numerous cells. Similar to Eukarya, Archaea have RNA polymerases that are more complicated than those of bacteria.
Archaea do not have peptidoglycan in their cell walls, in contrast to bacteria. The membrane lipid bonding of archaea differs from that of bacteria and eukarya.

The effect of carbon dioxide on the atmospheric temperature is BEST shown by graph
Answer: definitely C will help you
Explanation:
Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.
What is the main reason of emission of carbon?According to the information given in the question, we can state that global temperatures tend to increase as carbon emissions increase due to green house effect.
According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.
This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.
These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.
Therefore, Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.

The correct match of the features are:
Stalactites: Grow toward the cave floor.
Stalagmites: Grow toward the cave ceiling.
Swallow hole: A cave that has collapsed because of gravity.
Sinkhole: Where a stream disappears into the ground.
What are Stalactites?Mineral deposits known as stalagmites and stalactites are frequently seen in caves. The pointy, downward-pointing minerals that fall from the caves' roofs give rise to the stalactites.
On the other hand, stalagmites are created when minerals that fall from the roof are deposited on the ground afterward.

Rico and Bree are camping and have potatoes wrapped in foil to eat. Bree put her potato in the campfire for a while, but Rico did not. Now Bree's potato has a high temperature. What is the difference between the molecules of the two potatoes? *
There is no difference because both potatoes are made of the same type of molecules.
What is Molecules?Molecule is a group of two or more atoms that are bound together with the help of some attractive forces. These attractive forces are known as chemical bonds. It is the smallest particle of a substance that has all the physical and chemical properties of that substance.
Atoms have a single nucleus with a positive charge protons surrounded by a cloud of negatively charged electrons. When these come close to each other, the electrons interact with each other and with the nucleus, lowering the total energy of the system, then the atoms bond together to form a molecule.
There are three types of molecules:
1. Molecule of an atom
2. Molecule of an element
3. Molecule of a compound
Thus, there is no difference because both potatoes are made of the same type of molecules.

Explanation:
I hope this helps!
Answer:
b
Explanation:
The zygote is said to be Choose... , because it is able to develop into any kind of cell in the body. Adult stem cells are referred to as Choose... , because they can differentiate usually only into the cells of the tissues where they are found, whereas embryonic stem cells are Choose... because they can develop into any of the body’s cell types, although they cannot form the tissues surrounding the embryo.
Answer:
The correct answer is -
1. totipotent
2 multipotent
3. pluripotent
Explanation:
The cells that are able to develop or differentiate a different kind of cells in the body of the individual are known as totipotent cells and this ability is known as totipotency. An example of such cells is found in the zygote.
Multipotent on the other hand are the cells that are able to develop into a specific kind of cell of tissues these cells are present and the example of this type of cell is adult stem cells. Whereas Embryonic stem cells are Pluripotent cells that are characterized as the cells that develop into any type of cell of the body of an organism.
