1. Qué aprendí sobre el sistema Excretor Humano? 2. Qué aprendí sobre el sistema Excretor de los Animales? 3. Qué aprendí sobre el sistema Excretor de las Plantas?
Answer:
1.El aparato excretor se encarga de expulsar de nuestro cuerpo los desechos. Para ello utiliza el sistema urinario y las glándulas sudoríparas. El sistema urinario filtra la sangre para limpiarla de desechos y produce la orina. Las glándulas sudoríparas producen el sudor y regulan la temperatura de nuestro cuerpo
2.Su función es eliminar mediante un proceso de filtración los productos de deshecho resultantes del metabolismo celular o incorporados desde el medio ambiente, por ejemplo durante la alimentación, exceso de sal en las aves marinas, etcétera. El principal sistema de excreción en los animales es el sistema urinario
3.La excreción en plantas es para extraer sustancias que luego pueden ser utilizadas por ellas mismas para realizar sus funciones de fotosíntesis y de respiración, o bien, acumularla en sus vacuolas para sustancia de reserva. ... Se pueden acumular en vacuolas o espacios intercelulares
Which statement is correct about rough ER and smooth ER?
During a chemical reaction, the number of atoms
A stays the same
B increases
C decreases
D fluctuates
During a chemical reaction, the number of atoms stays the same
Atoms of elements are involved in chemical reactions. Atoms of different elements combine together to form molecules or compounds. According to the law of conservation of mass, matter cannot be created nor destroyed. This means that the number of atoms (matter) in the reaction does not increase or decrease but rather, stay the same.Atoms only get rearranged as they form new molecules and compounds, they however, do not change during chemical reactions.
Hence, atoms stay the same during chemical reactions.

Yeast is a fungus. It is used in many dishes to make fermentation. In making bread, the yeast is made active by putting it into warm water. Then, it is used in making bread, the flour will rise.
What is yeast?Yeast is a fungus that is used in the process of fermentation. Yeast is a single called eukaryotic organism that comes under the fungus kingdom. Yeast cells grow very faster than animal cells. Yeast cells are used to make bread and cakes. It is also used for alcohol making and baking process.
It usually remains inactive when it is added to the food material, but when it is added to warm water or thing, it becomes active and its cells increase in size.
Thus, as a fungus, yeast is. Fermentation is created using it in many different meals. The yeast is activated throughout the bread-making process by soaking it in warm water. The flour will then rise when it is used to make bread.

How will auxin influence cell growth in the roots of these plants?
Auxin will build up on the lower side of the root and inhibit cell growth.
Auxin will build up on the lower side of the root and stimulate cell growth.
Auxin will build up on the upper side of the root and inhibit cell growth.
Auxin will build up on the upper side of the root and stimulate cell growth.
Auxin is responsible for the growth of cells in the roots of plants. Auxin build up on the lower side of the root which inhibit the cell growth. Auxins have an inhibitory effect on primary root growth. Thus, the correct option is A.
What is Auxin?Auxin is a plant growth hormone, which promotes cell growth and elongation of the plant. In cell elongation, auxin alters the plant wall plasticity making it easier for the plant to grow upwards. Auxin also influences the rooting in the plant.
Auxins have an impact on the growth of roots. Auxins facilitate the initiation of roots in plants. These hormones induce both growth of root branching (root initiation) and roots that are pre-existing. They also play important role in the formation of the adventitious root.
Therefore, the correct option is A.

There’s a saying in brain science based on the work of Donald Hebb: neurons that fire together, wire together. The more they fire together, the more they wire together. In essence, you develop psychological resources by having sustained and repeated experiences of them that are turned into durable changes in your brain. You become more grateful, confident, or determined by repeatedly installing experiences of gratitude, confidence, or determination. Similarly, you center yourself increasingly in the Responsive, green zone – with an underlying sense of peace, contentment, and love – by having and internalizing many experiences of safety, satisfaction, and connection.
