Answer:
Ninguna de las dos. No ocurre ni mitosis ni meiosis.
Probablemente haya ocurrido fisión binaria/bipartición.
Explanation:
En este caso estamos hablando de bacterias, organismos unicelulares procariotas. Estos tienen una forma de reproducción asexual denominado fisión binaria. Los eucariotas por su parte pasan por periodos de división celular implicada en el crecimiento denominado mitosis, y división celular implicada en reproducción sexual, denominada meiosis.
La fisión binaria, también conocida como bipartición, si bien muy parecida a la mitosis en algunos aspectos, es la forma de reproducción de las bacterias.
Ambas, mitosis y fisión binaria, implican un duplicado de material genético. El ADN se duplica y una copia va a cada célula hija. Lo mismo sucede con el resto del contenido celular. Finalmente ocurre citocinesis. Sin embargo, a diferencia de la bipartición, la mitosis requiere de mecanismos mucho mas complejos de duplicación celular e involucra también a la cariocinesis, ausente en bacterias.
La fisión binaria ocurre muy rápidamente, en un breve período de tiempo puede hallarse una diferencia considerable en la cantidad de células presentes en un sustrato, producto de esta división. Es por esto que el crecimiento que exhiben las bacterias como población, sigue un modelo exponencial.

Which molecule regulates how the organism looks and acts?
Answer:
In a cell, proteins can act as enzymes, structural features, pigments, and a host of other functions, including regulating the expression of other genes. This expression of genes leads to how an organism looks – its phenotype.
Explanation:
Gene regulation creates different types of proteins which make the structure of cell and organism looks, so the gene is responsible for looks and acts.
What is gene regulation?Gene regulation is a critical component of proper development. During development, genes are switched on and off in diverse patterns to make a brain cell appear and perform differently from a liver cell or a muscle cell, for example.
Gene control also enables cells to respond swiftly to environmental changes. Genetic differences can result from gene variants (also known as mutations) or through a natural process.
Genetic information is reorganized when a cell prepares to divide (known as genetic recombination). Different features in an organism can be introduced via genetic differences that modify gene activity or protein function.
Therefore gene is responsible for how an organism looks and act, it creates different proteins to make a cell.

Healthy rain forest ecosystems provide ecosystem services, such as clean air, shade, food, and water. How might an increase in palm oil plantations affect humans who live nearby?
Answer:
Negatively affected.
Explanation:
Increase in palm oil plantations negatively affected humans who live in nearby area because this palm oil plantations is the cause of deforestation. Due to this palm oil plantations, deforestation occurs that leads to loss of habitat of many species as well as decrease in the area of forest which provides us clean air, shade, food, and water. The decrease in forest area also causes natural disaster such as floods in the region. Forests play a significant role in the prevention of floods in the region.
PLZ ASAP Coniferous trees flourish because they take the opposite approach of deciduous
trees, they grow (slow/ast) and die (young/old),
slow, old
fast, old
Slow young
Fast young
Answer: They grow slow and die old
Explanation: I just took a test with the same question and it said I was correct plus it is on this website https://untamedscience.com/biology/biomes/coniferous-forest-biome/
Coniferous trees flourish because they take the opposite approach to deciduous trees, they grow slowly and die old. Thus, the correct option for this question is A.
What are the characteristics of Coniferous trees?The characteristics of Coniferous trees are as follows:
They have leaves that are very thin in the shape of needles. These trees don't have flowers but produce cones. Due to this, they are called coniferous trees.These trees grow in areas that have snowfall. Hence these trees have needle-like leaves that do not allow the snow to rest on them.The approach and properties of coniferous trees are absolutely opposite to those of deciduous trees. This is because the environment of both conditions differs greatly.
When there are not enough nutrients present in the soil, coniferous trees generally flourish because they take the opposite approach with respect to deciduous trees. Due to this, they grow slowly and die old.
Therefore, coniferous trees flourish because they take the opposite approach to deciduous trees, they grow slowly and die old. Thus, the correct option for this question is A.

Why do you think there are so many bones in the cranium? Why do you think we are born with separate cranial bones that later fuse together as we grow and develop?
Hi, rachellelunaa!!
I think the reason we have so many bones is because, firstly, the cranium is such a unique shape that we need multiple bones to form it. Also, another reason we are born with separate cranial bones is that when a baby is born, there is an incredible amount of pressure being administered to the baby during the process. The many unfused bones allow the child's head to be malleable, and therefore preventing damage to the skull and brain. As we grow, we no longer need these bones to be malleable and they fuse together.
I really hope this answers your question!!
The sutures are flexible, the bones can overlap during birthing, preventing the baby's head from pressing against the baby's brain and causing damage.
What are the cranial bones?Skeletal structure of the head. The cranium, which surrounds and protects the brain, is made up of cranial bones and facial bones (bones that form the eye sockets, nose, cheeks, jaw, and other parts of the face).
The two remaining cranial bones are covered by the frontal bone. The sphenoid bone and ethmoid bone are these.
Behind your eye sockets, the sphenoid bone supports the muscles of your face. At the peak of your nose, between your eye sockets, is the ethmoid bone.
Therefore, preventing damage to skull and brain, we are born with separate cranial bones.

Victor put a match on a balance and found that its mass was 6.0 grams. Then he lit the match and put it out after a few seconds.
He put the partially burned match on the balance again. This time, its mass was 4.5 grams.
Which of the following best explains what happened as the match burned?
A.
Some of the mass was destroyed by the fire.
B.
The mass of the match combined with the mass of the fire.
C.
The matter moved to a different part of the match.
D.
Some of the matter changed from solid to gas and went into the air.
Answer: It releases oxygen and heat. The answer is C
Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together the heat, the fuel, and the oxygen you get a flame. Matter does not go when something is set on fire. Matter is always the same. Burning is a chemical process. The flames are caused as a result of a fuel undergoing combustion (burning). (CC BY-SA 2.5; Einar Helland Berger for fire and Walter Siegmund for ash).
