Behind your house, there's a gorgeous pond filled with frogs. You notice that the frogs behind Mr. Archer's house often have three legs. You start wondering if the fertilizer that Mr. Archer uses for his lawn is causing the deformities in the frogs. You collect 10 frogs and put the special fertilizer in their container (Group A). You put another 10 frogs and place them in a different container with just water (Group B). A week later, 7 out of 10 of the frogs in group A grew only three legs. The frogs in group B grew four legs.

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.

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

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.

Which of the statements below correctly compares features of plant and animal cells?
Plant cells have a cell membrane, while animal cells have both a cell wall and a cell membrane.
Plant cells have ribosomes only on the rough ER, while animal cells have ribosomes in the cytoplasm.
Plant cells have a large central vacuole, while animal cells have many smaller vacuoles.
Plant cells have chloroplasts but no mitochondria, while animal cells have mitochondria.
Plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.
What are vacuole?Vacuole is defined as a region of cytoplasm-free, membrane-lined, and liquid-filled space inside a cell. A membrane-bound cell organelle known as a vacuole. The plant cell's equilibrium depends heavily on the vacuole. It participates in the regulation of cytoplasmic ions, pH, and the control of cell volume and turgor.
Animal cells lack a cell wall, whereas plant cells do. Animal cells lack chloroplasts while those of plants do. Animal cells have many little vacuoles, but plant cells only have one giant vacuole. Animal cells only have a cell membrane, but plant cells have both a cell wall and a cell membrane. Cell walls are used by plants to give the plant structure. Animal cells lack the organelles known as chloroplasts that are present in plant cells.
Thus, plant cells have a large central vacuole, while animal cells have many smaller vacuoles. Hence option c is correct.

Explain why men should not accuse women of not delivering male child for them
Men should not accuse women of not delivering a male child for them because they are not responsible for determining the gender of the child. It all depends on the fusion of chromosomes.
How zygote is formed?The Zygote is formed after the successful fusion of male and female gametes.
Women bear both XX chromosomes, while men bear one X and one Y chromosome. It is a biological phenomenon of fusing these sets of chromosomes and determining the gender of the child.
Therefore, it is well described above.

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.

describe the role. of the liver in regulating the concentration of glucose in the body
Answer:
The liver stores glucose to power the cells during periods of low blood sugar. Skipping meals and poor nutrition can lower blood sugar. By storing glucose, the liver makes sure that blood glucose levels remain steady between meals and during sleep. When blood glucose falls, cells in the pancreas secrete glucagon.
