Answer: When is blood pressure considered high? Normal blood pressure is under 120/80. From 120/80 to 139/89 is pre-hypertension. The threshold for high blood pressure is 140/90, while anything over 180/110 is hypertensive crisis – an emergency.
Explanation:
Use the scenario to answer the question.
You observe the growth of a group of plants that have been tipped over.
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.

you can help Susan solve the problem
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.

The enzyme changes the substrate to create a _______.
Answer: an enzyme products complex.
Explanation:
To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. This forms the enzyme-substrate complex. The reaction then occurs, converting the substrate into products and forming an enzyme products complex.

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.

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.

Please answer ASAP... Ill give brainliest
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.

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.

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
