Answer:
Humans have holozoic nutrition, that means the food is consumed as a whole and the digestion occurs internally. It can be described as:
1. Ingestion of food- The food is taken in the oral cavity in the process called the ingestion. The teeth help in grinding of the food, salivary amylase helps in partial breakdown of the starch and the tongue helps in mixing the food with saliva and helps in swallowing it. The food is now called bolus.
2. Digestion- The process of break-down of complex substances into simpler substances is called digestion and it starts with the mouth where physical break-down occurs along with some chemical digestion. The bolus is swallowed in and it arrives in stomach where the digestion of proteins occurs due to presence of the enzyme pepsin. Bolus is now called the chyme. This chyme now moves into the small intestine where rest of the process of digestion will be completed. The pancreatic juice, the intestinal juice and the bile will result in breakdown of carbohydrates, fats and the rest of the proteins. The chyme is now called the chyle and it moves to the large intestine where the water is absorbed.
3. Absorption- The digested food is absorbed via the finger-like projections present on the inner surface of the small-intestine and the reach the blood stream.
4. Assimilation- The absorbed food is then used by different tissues for the energy generation. The excess food is stored as glycogen in the liver and s fats in adipose tissue.
5. Excretion- The undigested material passes from the small-intestine to the rectum of the large-intestine, from where it is removed from the body through anus.

Which star has an temperature of 10,000 K and a Luminosity of 10^2
Answer:
i think White Dwarf
Explanation:
We are given that the star has a temperature of 10,000 K and a luminosity of 10^2. According to the HR diagram, a star with the surface temperature of 10,000 K would be a white dwarf and if the star were on the main sequence, then it would have a luminosity nearly 100 times more than that of the sun. However since the actual luminosity is 10,000 times smaller than this, this star must be a white dwarf since it has 10,000 K and 100 aka 10^2 luminosity
Answer:
It is main sequence, my dear...

The kidneys filter the blood by creating urine. The blood has to travel through these tissue cells to get into the kidney. There are lots of elastic tubes that the soon to be urine travels through while being filtered. The kidneys rely on blood pressure from the heart to move the liquid so lack muscle tissue. The kidneys do not control when you urinate as they simply pass the urine in to your bladder. Explain why the kidneys have each tissue listed below or why they don’t have each tissue.
Muscle Tissue :
Epithelial Tissue :
Nervous Tissue :
Connective Tissue :
Answer:
Muscle Tissue : The kidneys rely on blood pressure to move, since they lack muscle tissue.
Epithelial Tissue : The kidneys contain simple cuboidal epithelial tissue, which secretes and absorbs. Thus absorbing toxins from blood to be turned to urine.
Nervous Tissue : Kidneys to not contain nervous tissue due to the fact that they do not control when you urinate, but rather simply just pass the urine to the bladder.
Connective Tissue : Kidneys do contain Connective Tissue, called renal fascia, in order to keep the many elastic tubes in place, and a capsule of renal fascia closely envelopes each kidney to protect, and provide support for each kidney inside.

What is ridge push?
Answer:
Ridge push (also known as gravitational sliding) or sliding plate force is a proposed driving force for plate motion in plate tectonics that occurs at mid-ocean ridges as the result of the rigid lithosphere sliding down the hot, raised asthenosphere below mid-ocean ridges. Although it is called ridge push, the term is somewhat misleading; it is actually a body force that acts throughout an ocean plate, not just at the ridge, as a result of gravitational pull. The name comes from earlier models of plate tectonics in which ridge push was primarily ascribed to upwelling magma at mid-ocean ridges pushing or wedging the plates apart. Brainliest?
Explanation:
Which of the following is not among the kinds of specialised cells in man? a. Reproductive cells b. Nervous tissues cells c. Digestive cells d. Blood cells
the answer is the blood cells
The one that is not among the kinds of specialized cells in man is digestive cells, the correct option is c.
What are specialized cells?Specialized cells are cells that are designed to perform a specific function in the body, such as red blood cells, which are designed to transport oxygen.
Nerve cells assist in the contraction or relaxation of muscles depending on the specific job at hand.
The intestinal epithelium contains a variety of cell types, including enterocytes, Paneth cells, goblet cells, and neuroendocrine cells. The main cell type in intestinal epithelium is enterocytes.
Specialized cells form tissues, tissues form organs, and organs form the systems that make up our bodies. Specialized cells include nerve cells, blood cells, and reproductive cells.
Thus, the correct option is c.

Artificial Selection
Adaptations
Natural Selection
Best Fitness
Answer:
I would say Artificial Selection.
Explanation:
Khan Academy defines Artificial Selection as: "Artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection." The other options seem a bit irrelevant to the question.
Answer:
Artificial Selection
Explanation:
Artificial selection involves selecting breeding. This is when farmers breed two plants which bear the largest, sweetest or tastiest fruits or which give high yields of the crops. The same process happens in cows, where farmers select animals to breed, based on high milk yield, or meat production.
However, farmers are becoming to think more differently in order to improve the welfare of animals. Instead of high yields, they are looking to increase disease resistance among animals and plants alike. Banana breeders are looking towards wilder plants with more disease resistance. But all in all, it is artificial selection. It's not bad, as it increases nutritional values for us humans.

Consumir alimentos que contengan un alto valor nutricional para evitar la desnutrición, el sobrepeso y la obesidad. La célula necesita energía en forma de ATP para realizar sus funciones vitales. Esta energía la obtenemos de la glucosa presente en los alimentos, por lo que siempre debemos considerarla en
nuestro consumo diario. Las células necesitan carbohidratos, lípidos, proteínas y minerales para realizar sus actividades vitales y mantener el equilibrio homeostático.
Incluir en la alimentación quinua para prevenir la anemia.
Algunos de los alimentos que presentan un alto valor nutricional incluyen el arenque, la espinaca, arvejas, semillas de calabaza, etc. La energía de la glucosa se convierte en ATP mediante la respiración celular.
La célula necesita macronutrientes y micronutrientes para sobrevivir.
Los macronutrientes son aquellos que aportan energía al ser consumidos, los cuales incluyen lípidos, proteínas y carbohidratos.
Los micronutrientes no aportan energía e incluyen las vitaminas (por ej, la vitamina D) y los minerales (por ejemplo, el hierro).
Los alimentos que presentan un alto valor nutricional son aquellos que contienen un alto contenido de macro y/o micronutrientes (por ejemplo, arenque, espinaca, arvejas, semillas de calabaza, etc).
Los carbohidratos simples como la glucosa aportan energía de rápida utilización mediante la ruptura de sus enlaces químicos, lo cual permite llevar a cabo un grupo de reacciones metabólicas colectivamente referidas como respiración celular.
La respiración celular genera ATP, la moneda de cambio energética que la célula utiliza para crecer, diferenciarse y reproducirse.
Finalmente, la quinoa es un alimento del grupo de los cereales el cual contiene un alto valor energético y nutricional.
Este alimento (quinoa) es una fuente rica en hierro (es por ello que previene la anemia), magnesio, calcio y diferentes tipos de vitaminas (B, C y E).
