Answer:
1.Blood pressure can be defined as the pressure of blood on the walls of the arteries as it circulates through the body. Blood pressure is highest as its leaves the heart through the aorta and gradually decreases as it enters smaller and smaller blood vessels (arteries, arterioles, and capillaries).
2. The more rounded the lumen, the less surface area the blood encounters, and the less resistance the vessel offers. Vasoconstriction increases pressure within a vein as it does in an artery, but in veins, the increased pressure increases flow.
If the pair of materials listed below were rubbed together, give the charge that each would have in the same order as listed. use short-form P and N. silk and paraffin wax
Answer:
Simply put, the property of electron affinity refers to the relative amount of love that a material has for electrons. If atoms of a material have a high electron affinity, then that material will have a relatively high love for electrons. This property of electron affinity will be of utmost importance as we explore one of the most common methods of charging - triboelectic charging, also known as charging by friction or rubbing.
Suppose that a rubber balloon is rubbed with a sample of animal fur. During the rubbing process, the atoms of the rubber are forced into close proximity with the atoms of the animal fur. The electron clouds of the two types of atoms are pressed together and are brought closer to the nuclei of the other atoms. The protons in the atoms of one material begin to interact with the electrons present on the other material

In the Punnett square, fill in the shaded boxes with the alleles of each parent. Use B for the
dominant allele (black fur) and b for the recessive allele (white fur). THIS ONE IS A SECOND ONE PLEASE HELP
Answer:
you gotta put the small "b" for the female and all the the box will be "Bb"
The dominant allele (black fur) has alleles B and b for the recessive allele (white fur), so the offspring will all have bodies with black fur.
What is phenotype?Phenotype is the physical appearance of characters which is the result of genes which express in the cell to give a particular trait in the diagram black is dominant over white so all the offspring show a black phenotype.
Male genotype: BB
Female genotype: bb
Cross: BB X bb
Gametes: B, B, b, b
All progeny will be black having genotype Bb, Bb, Bb, Bb.
The Cross is uploaded in the image below.
Genotype is the genetic appearance of the allele which shows the gene is responsible for a particular trait.
Therefore, the dominant allele (black fur) having allele B and b for the recessive allele is crossed, and all progeny will be black having genotype Bb, Bb, Bb, Bb.

During the light reactions of photosynthesis, plants convert light energy into energy the plant can use. Where is the energy stored
Answer:
Photosynthesis is a process where plants and other organisms convert energy from the sun into a chemical energy that through cellular respiration can be later released in order to fuel the organism's metabolic activities.
The energy which is stored in the form of sugar is broken down into starch entering the mitochondria to produce energy. The energy is stored in the chemical bonds. To obtain the energy, organisms take energy-rich compounds such as glucose and breaks them down to release their energy. The organism traps the released energy and stores it in a form of adenosine triphosphate or ATP.

1. Juan es un estudiante joven que hace poco se mudó a su propio departamento. Realiza actividad física desde siempre pero últimamente nota que se cansa más rápido, tiene poca fuerza y ha perdido algo de peso. No entiende la causa porque sigue comiendo en forma abundante. Visita a su médico, quien le informa que tiene pérdida de masa muscular y le pregunta si está alimentándose correctamente. ¿Por qué le hace esta pregunta? ¿Qué tiene que ver la comida con el músculo?
Answer:
Es posible que Juan sospeche que no está alimentándose correctamente (comer en grandes cantidades no significa estar bien alimentado)
Explanation:
Las proteínas representan un macronutriente esencial que debe ser consumido a través de la dieta para crecer en masa muscular y también para mantener la masa de los músculos. Las proteínas están compuestas por muchos tipos diferentes de aminoácidos (los bloques de construcción de las proteínas), pero solamente 20 aminoácidos conforman las proteínas que se encuentran en el cuerpo humano. Los aminoácidos esenciales son aquellos que el cuerpo no puede sintetizar por sí solo. Estos aminoácidos esenciales son: histidina, fenilalanina, treonina, lisina, metionina, triptófano, valina, isoleucina y leucina. El consumo diario recomendado por la Organización Mundial de la Salud (OMS) de proteínas en un hombre adulto es 0,8 a 1 gramo por kilogramo de peso corporal. Además, es posible que el cansancio que experimenta Juan se deba a alguna deficiencia en micronutrientes esenciales, es decir, debido a la falta de vitaminas y minerales, los cuales también deben ser consumidos a través de la dieta. Por ejemplo, la fatiga puede deberse a la falta de hierro, un mineral fundamental cuya deficiencia lleva a cuadros severos de anemia. Similarmente, la deficiencia en vitamina D puede también causar agotamiento o fatiga crónica, entre otros síntomas (por ej., abruptos cambios en el estado de ánimo, debilidad ósea en los huesos, daño en el estómago, etc). Por otra parte, es importante remarcar que no se debe descartar la posibilidad de que el cansancio experimentado por Juan se deba a un cuadro de estrés y/o algún otro tipo de problema de salud, siendo por lo tanto necesario una descripción más detallada del cuadro clínico para obtener una conclusión más precisa de su situación.

A certain stem cell produces only muscle cells. What kind of stem cell is this?
A. Pluripotent
B. Unipotent
C. Totipotent
D. Multipotent
the answer is (B. Unipotent)
Answer:
B) unipotent
Explanation:
Unipotent stem cells come from multipotent stem cells which can only become a few different cell types. Unipotent stem cells can be programmed to be only a specific cell type. They will only follow that one genetic path, thus the name "uni".
Which describes a way in which phosphorus may enter into the phosphorus cycle?
Earthquakes release phosphorus.
Phosphorus is carried in the rain that was evaporated from lakes.
Human use of fertilizers release phosphorus into the groundwater.
Phosphorus is transpired from the leaves of plants.
Answer:
I think the correct answer from the choices listed above is option C. A way in which phosphorus may enter into the phosphorus cycle is that when human use of fertilizers release phosphorus into the groundwater. Hope this answers the question. Have a nice day.
Human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle. Therefore, the correct statement is option C.
What is the use of phosphorus?Phosphorus is a nutrient needed by plants to grow, and it is added to soil in the form of fertilizers. When it rains, the phosphorus is washed away from the soil and carried into nearby rivers, lakes, and groundwater.
The phosphorus is then taken up by plants or become part of the sediment at the bottom of bodies of water.
Phosphorus can be transformed from there and recycled through the different parts of the phosphorus cycle, such as weathering, erosion, and sedimentation. Phosphorus can also be released from the decomposition of organic matter.
Therefore, human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle.

Workout the path taken by a carbon molecule as it moves from being part of the co2 in the air to being part of a starch molecule in a plant
Answer: The conversion of carbon dioxide occurs into glucose via photosynthesis.
Explanation:
The plants absorb carbon dioxide gas from the atmosphere. This is one of the reactants of the photosynthesis process. The water and carbon dioxide are the reactants of the photosynthesis process in the presence of sunlight the molecule of water splits into hydrogen and oxygen gas is liberated as byproduct and carbon dioxide becomes the product of the glucose. The monomers of glucose combine to form starch molecule which is stored as energy reserve in plants.
