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.

Answer: movement is always voluntary
Explanation:
Muscles are contractile:
- Contractility is the ability of muscle cells to forcefully shorten. Think of having the ability to flex a muscle.
Muscles are excitable:
- Excitable tissue can conduct or transmit electrical impulses. Basically, it can react to stimulus, which may be delivered from a motor neuron or a hormone. For example, the hormone epinephrine helps muscles to produce force.
Muscles respond to stimulus:
- well since muscles are an excitable tissue, they can react to stimulus. (see answer above)

Muscle movement is NOT always voluntary:
- Some muscle movement is voluntary, which means it is under conscious control. For example, a person decides to open a book and read. Other movements are involuntary, meaning they are not under conscious control, such as the contraction of your pupil in bright light, breathing, blinking, your heart beating, etc.
- Therefore, the correct answer is:
movement is always voluntary
hope this helps :)
Answer:
6 chromosomes each
Explanation:
Meiosis is the cell division that results in daughter cells with a reduced number of chromosomes (by half). Meiosis is used only by sexually-reproducing organisms to produce gametes. Since meiosis reduces the chromosomal number, it occurs in a two-step division process viz: Meiosis I and Meiosis II.
Meiosis I involves separation of homologous chromosomes (similar but non-identical chromosomes received from each parent). In the Anaphase stage of meiosis 1, each homologous pair of chromosomes that makes the organism diploid (2n) is separated. Hence, the resulting cells of meiosis I will have a reduced chromosome number (haploid,n).
In this case of a diploid frog with 12 number of chromosomes. If a germline cell or reproductive cell divide by meiosis, in meiosis I, each pair of the 6 pairs of homologous chromosomes of the frog will separate into opposite cells. Hence, at the end of meiosis I, each daughter cell will have 6 chromosomes in a haploid state.
In meiosis II, sister chromatids (replicated chromosomes) separate instead. Each separated chromatid becomes a full chromosome in each gamete.
