Explanation:
Answer:
Pattern Formation
Explanation:
Cytoplasmic determinants and inductive signals both contribute to the development of a special organization in which the tissues and organs of an organism are all in their characteristic places, a process known as pattern formation.

Answer:
A graph not only depends on the data that we are graphing, there are other important factors such as the units we use (here we have °C vs years, but we could have °F vs days and we would see a different graph, which represents the exact same information) , the scale we use (a lot of graphs are misleading because of the use of logarithmic scales, we need to be clear about the scales we use), where we put the zero of each axis (We usually use the intersection of both axes as the (0, 0) point, but this is not a necessary condition, we could manipulate our coordinate axis as we want) , etc.
So there are a lot of things that can impact on how we see the graph of the same data.
About the second answer, one could interpret from that graph that the actual temperature between the years 1880 and 2020 was around 14°C.

1. Name the protists fitting each of the following descriptions.
Write down only the correct name next to the relevant question number.
1.1 A protozoan which moves using its pseudopodia.
1.2 A protozoan which moves using its flagellum.
1.3 A filamentous green alga.
1.4 A unicellular green alga.
1.5 Microscopic protists which appear as symmetrical, human-made, and
glass-like ornaments.
1.6 Protists that look like fungi.
(6)
Answer:
1.1 Amoeba
1.2 Paramecium
1.3 Citations
1.4 Single algae cells
A protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.
What are Protists?A protist is a type of eukaryotic organism which is not an animal, plant, or fungus sharing a common ancestor. These are to the exclusion of other eukaryotes which means protists do not form a natural group or clade.
Protists are a group of diverse eukaryotic mainly unicellular microscopic organisms which share certain morphological and physiological characteristics with animals or plants or both.
Several protists showing different functions like an amoeba pushes out its cell membranes to form pseudopods. Euglena belongs to the class of protozoans known as flagellates. Spirogyra has a slender bright green color with a spiral shaped pigment that holds chlorophyll. Chlamydomonas is found in ponds, ditches and moist soil. Diatoms have a silky jewel-like covering. A mold is a protist which is a fungus.
Thus, a protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.

Explain the changes in the number of algae in the lake from February to June (3)
ANSWER
Answer:
Kindly check explanation
Explanation:
According to the graph given the number of algae is represented on the y axis while the month of the year is represented on the x - axis of the graph. The change in the number of algae from February is clearly depicted by an upward slope along the y-axis which means that there is continous increase in the Number of algae in the lake during this period, that is between February to June . It could also be seen that around June the optimal number of algaae is achieved as the number of algae tend to fall as we move beyond June.

What process is the driving force behind evolution?
Answer:
Mutations and natural selection are the main ones
Explanation:
The process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.
What is the significance of natural selection over time?Natural selection is important for the survival of organisms as it is a process by which populations of organisms change over time in response to the outer environment. It is also an important evolutionary mechanism because natural selection always chooses the fittest and natural selection also drives the development of new species and helps ensure the survival of existing species.
Hence, the process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.
