Answer:
Explanation:
Venimos de la ameba. A alguno le puede sorprender su antepasado, pero este episodio evolutivo ya se había descrito con anterioridad. Hasta ahora el misterio era cómo un organismo de una sola célula había conseguido reunir decenas de billones de ellas en las primeras formas de vida animal, hace unos 700 millones de años.
Answer:
The correct option is b. G1 phase. When a newly formed cell enters into interphase and begins conducting metabolic functions, it is in <u>G1 phase.</u>
Explanation:
The cell cycle comprises a whole series of events or phases that take place in the cell during its growth and division. A cell spends most of its time at the stage called<em> the interface</em>, and during this time it grows, duplicates its chromosomes and prepares for cell division. The cell cycle has different phases, which are called G1, S, G2 and M.
G1 phase is that in which the cell prepares to divide, during this phase, the cell grows rapidly, while performing routine metabolic processes. It also produces proteins necessary for DNA replication and copies some of its organelles in preparation for cell division. A cell normally spends most of its life in this phase. This phase is also known as Gap 1 phase and actively synthesize RNA and proteins.
G0 phase is a period or cycle of a cell where it remains in a resting state, in this phase mature cells that leave the cell cycle are placed.
G2 phase, during this stage, the cell makes the final preparations for its division.
B replaced because it takes place when water dissolves the original hard parts and replaces them with mineral matter.
Answer:
B. Water evaporates more quickly when temperatures are high
Explanation:
Constructing an hypothesis is KEY to any experimental setup. It is the first thing to do in accordance to the scientific method. A hypothesis is simply a predicted statement that aims at proferring solution that is subject to testing via experimentation.
According to this question, Mae observed that the birdbath in her backyard loses water more quickly during hot summer days than during the cooler days of the spring. A suitable hypothetical statement for this observation would be: "Water evaporates more quickly when temperatures are high".
N.B: Hypotheses are not questions
Answer:
due to gmos we can expand the shelf life of many of our foods and prevent them from the harm of pests. You night be rhinking why not use pesticides? well, we did but eventually the pests became immune to the low dose of pesticide. over time we gradually increased our uses of pesticides. more commonly round up. this pesticide specifically was known for being a carcinogen. (something that causes cancer.) Genetically modifying a crop can severely decrease the amount of pesticides used for our crops and could also potentially drop the prices. for example, in hawaii during the 1940s to 1990s the ringspot viruses hit the hawaiian papaya harvest hard. this reduced the amount of papaya produced by 50 percent by 1993 and 2006. the ringspot virus nearly wiped out the entire crop. within 11 months, the hawaiian papya was saved. due to gmos of course. this is because scientists took genes from immune papayas which very rarelt occured (at the time) and injected it into many other papya plants. as the plants grew, new papaya was produced which was immine to ringspit virus. PAPAYA WAS SAVED!!!!

I hope this helped! :) Have a nice day!
