Thermoses work because they minimize which kinds of heat transfer?
A.Conduction and convection
B. Conduction and radiation
С. Convection and radlation
D. Conduction, convection, and radiation
Answers
Answer:
B or C
Explanation:
I read about this awhile ago just forgot if it was ethier conduction or convection
The thermal heat energy transfers through various modes. Thermoses work because they minimize conduction and radiation transfer of heat. Thus, option B is correct.
What is heat transfer?Heat transfer has been the process that moves the heat from higher temperature towards the area of lower temperature. Conduction, convection, and radiations are the three modes of heat energy transfer.
In conduction, the heat flows from one body to another when they are in contact, and in radiation the heat flows in the waveform that does not need any direct contact. It needs an indirect medium to transfer the heat from high to lower temperatures. Thermoses do not show convection as it keeps the temperature constant.
Therefore, option B. thermoses use conduction and radiation.

Explain why the chemical equation for photosynthesis is a simplified representation of the process. How is the equation accurate? How is it inaccurate?
Answers
Answer:
The equation shows the general reactants and products of the process. However, it does not show intermediate steps. For example, carbon dioxide and water do not actually react with each other.
Explanation:
The equation is representing the general reactants and products of the process. But, it does not express the intermediate steps. For example, carbon dioxide and water do not actually react with each other.
What is photosynthesis reaction?The procedures by which chlorophyll bearing organisms and certain other microbes transforms sunlight to chemical energy is renowned as photosynthesis.
Light energy is grasped and utilized by green plants in the process of photosynthesis to efficiently convert, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Plants grab these carbon dioxide as well as water from either the environment or soil during photosynthesis.
Water is oxidized within the plant cell, which means it loses electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.
The equation represents the process's broad sense reactants and products. It does not, however, convey the intermediate steps. Carbon dioxide and water, for example, don't really actually react with each other.
Thus, that's why the equation is perhaps not accurate.

Excretion
Explanation:
The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. When cells break down proteins, they produce nitrogenous wastes, like urea. The excretory system serves to remove these nitrogenous waste products, as well as excess salts and water, from the body.
Si durante la division de las celulas de la raiz de una planta se aplica una sustancia x que destruye el complwjo de golgi de estas celulas¿cual sera el efecto esperado en dicho tejido
Answers
Answer:
cada célula tendrá dos núcleos
Explanation:
El complejo o aparato de Golgi es un organela compuesta por un grupo de membranas apliladas una sobre la otra formando una serie de sacos aplanados. El complejo de Golgi tiene diversas funciones: maduración, modificación (glicosilación), transporte y secreción de proteínas. En células vegetales, el aparato de Golgi sintetiza vesículas que forman parte del tabique telofásico el cual sirve para dividir el citoplasma de células vegetales durante la citocinesis. En consecuencia, si se eliminara esta organela, el tabique telofásico no se formaría y las células resultantes estarán compuestas por dos núcleos.

Which statement best describes a dormant plant? *
1.It is in need of food,
2.It is hardy
3.It is inactive
4.It is fast growing
Answers
Explanation:
Dormant plants are plants that are able to endure and survive in such harsh conditions. Looking at the definition of “Hardy” it is indeed the correct answer.
Also If you wanted, you could use process of elimination to answer this question.
1. It is in need of food.
While this may be half true, it isn’t fully correct because most dormant plants have waxy covered leaves, or some storage function to save water. That allows them to survive.
2. It is hardy.
This is true because dormant plants are very strong plants for being able to survive in such harsh conditions. That being said this answer is most likely correct.
3. It is inactive.
Dormant plants are kind of like hibernating bears because they store and collect to survive but there is one difference and it’s that bears go to sleep and are inactive while these plants remain active.
4. It is fast growing.
This is kind of hard to answer but there is one thing that makes this answer not correct and it’s that this doesn’t correlate to the original question. What does a dormant plant have to do with fast growing?
Looking at all these answer choices, we have managed to find the (hopefully/most likely) correct answer.
I hope this helped you! :)

Answer: B is the answer
Following mitosis, the daughter cells would each have a total of 46
chromosomes.
After meiosis I, the two daughter cells would have 23 chromosomes, and
after meiosis II it will still remain as 23 chromosomes.
Mitosis is a type of cell division that involves the production of identical
daughter cells. The daughter cells usually contain 46 chromosomes with all
the parent traits present.
Meiosis is a type of cell division which produces sex cells and for
reproduction. It involves generating unique daughter cells which is gotten by halving the 46 chromosomes to become 23 chromosomes.
