Explanation:
OK, first of all, let me explain to you, what is a scientific theory...
A scientific theory is an explanation and demonstration of an aspect that exists in the natural world or universe that has been verified by the scientific way through repeated testing of the experiment with accepted protocols of observation, measurements and evaluation of results.
A scientific law is generated in the same procedure as above, but it can predict a wide range of natural phenomena.
Ex-: you are throwing a basketball from the top of a dam to the river. according to physics on earth, it should fall down. it's a law. no matter where you are, that basketball touches down the ground if there's any gravitational force.
But cell theory cannot be assumed to be common throughout the entire universe. Because we may find some other form of life that has some other plans. viruses are not obeying this theory.
*In a nutshell, a law is stable from its' origin. most of the time, it won't change. but theories will change with updating facts of science.
cytokinesis in plant cells involves the formation of
Answer:
Cytokinesis in plant cells involves the formation of the insertion of a new cell wall that separates daughter nuclei after mitosis
Cytokinesis involves the formation of the insertion of a new cell wall that separates daughter nuclei and produce two new daughter cell.
What is cytokinesis ?It is the final stage in the cell cycle, when a new daughter cells is formed from parent cell through the splitting of the cytoplasm and the separation of the two identical cells.
In Stage 1 cleavage furrow is seen where the actin filaments will begin to tighten around the cells, spindle formation occur, t the chromosomes are divided evenly between the two nuclei. The spindle possesses small structures called astral microtubules guide the alignment of the actin filaments along the future cleavage furrow.
In Stage 2 the gathering of the actin filaments occur where some protein called myosin facilitates the pulling of the actin filaments, and formation of contractile ring begins.
In Stage 3 the myosin a motor protein with the help of ATP, it is able to contract the contractile ring, deepening the cleavage furrow, causing the cell to narrow in the middle as two daughter cells form.
In Stage 4 the actual breaking of the cell membrane and the membrane quickly refuses at the broken point and two independent and identical daughter cells are produced.

un estudio sanguineo al que fue sometido carlos arrojo los siguientes resultados (mg/ml): glucosa 90, trigliceridos 120, hemoglobina,14 y acido urico 6.¿ cual de ellos corresponde a un lipido?
un estudio sanguineo al que fue sometido carlos arrojo los siguientes resultados (mg/ml): El que corresponde a lípidos son los triglicéridos.
Los resultados del estudio de sangre al que fue sometido Carlos son:
glucosa = 90 mg / ml triglicéridos = 120 mg / ml hemoglobina = 14 mg / ml ácido úrico = 6 mg / mlA partir del resultado dado, la opción que corresponde a los lípidos son los triglicéridos.
Los triglicéridos son lípidos (grasas cerosas) que proporcionan energía al cuerpo. Los triglicéridos son producidos por nuestro cuerpo y se obtienen de las comidas que ingerimos. Un triglicérido es un tipo de lípido compuesto por glicerol y tres moléculas de ácidos grasos.
La glucosa tiene la fórmula molecular C6H12O6 y es un azúcar simple. La glucosa es el monosacárido más ubicuo que es un tipo de carbohidrato. La glucosa es producida principalmente por plantas y algas cuando realizan actividad fotosintética a partir del agua y el dióxido de carbono con la ayuda de la luz solar, donde se utiliza para crear celulosa en las paredes celulares.
La hemoglobina es una proteína que se encuentra en los glóbulos rojos (RBC) que transporta oxígeno a los órganos y tejidos y transporta el dióxido de carbono (CO2) de los órganos y tejidos de regreso a los pulmones.
El ácido úrico es un producto de desecho que puede detectarse en la sangre. Se forma cada vez que el cuerpo descompone las purinas. La mayor parte del ácido úrico se disuelve en la sangre, viaja a través de los riñones y se excreta en la orina.
Por tanto, de la explicación anterior, podemos concluir que el resultado que corresponde al lípido son los triglicéridos.

what do the three major checkpoints for cell division have in common?
Answer:
There are three major checkpoints in the cell cycle: one near the end of G1, a second at the G2/M transition, and the third during metaphase. Positive regulator molecules allow the cell cycle to advance to the next stage. ... Each successive cell division will give rise to daughter cells with even more accumulated damage.

starts when two atoms slam together to form one, heavier atom
starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms
Answer:
to study the nature and size of the image formed by a convex lens using a candle and a screen activity file
The statement that describes nuclear fission is as follows:
Starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms.Thus, the correct option for this question is D.
What is Nuclear fission?Nuclear fission may be defined as a type of nuclear reaction during which the nucleus of an atom splits into two or more smaller nuclei due to the impact of another particle with the liberation of a very large amount of energy.
Nuclear fission is a process where a heavy nucleus is bombarded through neutrons and due to this, it becomes unstable. This causes it to decompose into two or more nuclei spontaneously with equivalent size and magnitude. It involves a tremendous detachment of energy as well as the emission of two or more neutrons.
Therefore, the statement "starts when neutron slams into an atom, causing the larger atom to split into two smaller atoms" describes the process of nuclear fission. Thus, the correct option for this question is D.

10. Explain how both a population of moose and wolves in the same area could each affect the
size and distribution of the plant population in a community:
Answer:
Since moose are herbivores, they could cause a plant population to decrease in size.
Since wolves are carnivores and hunt moose, there would be less moose feasting on plants, so the plant population would be allowed time to grow back larger.
Depending on how many wolves there are to moose, the plant population will tend to vary.
For example: If the moose population is greater than the wolf population, there will be a smaller population of plants. On the other hand, if the wolf population is greater than the moose population, there will be a greater population of plants.

Answer:
D
Explanation:
Only some organisms reproduce asexually, only plants perform photosynthesis, and most creatures consume oxygen and release carbon dioxide.

All complex life is made out of many many many cells.

what forms after the glycosidic linkage reaction between glucose and galactose is complete
What forms after the glycosidic linkage reaction between glucose and galactose is complete would be lactose.
Glucose and galactose are known as simple sugars or monosaccharides. Monosaccharides can combine together to form disaccharides or even polysaccharides.The combination of monosaccharides to form di or polysaccharides happens by a process known as condensation reaction.The condensation reaction results in the formation of glycosidic linkage or bond and elimination of water moleculesGlycosidic bond is a type of covalent bond th joins one sugar molecule to another sugar or non sugar molecule.Thus, lactose is a dissacharide consisting of one glucose and one galactose unit which combine together by condensation and formation of glycosidic bond with elimination of water.
