Which star has an temperature of 10,000 K and a Luminosity of 10^2

Answers

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

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​

Answers

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.

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 :

Answers

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.

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.

Answers

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).

Which enzyme is missing in a cell where replication bubbles form and RNA primers are present but no DNA replication takes place?

Answers

The answer is DNA polymerase 3

The missing enzyme is DNA polymerase.

DNA replication is a complex process that involves the duplication of the DNA molecule in a cell. One of the key enzymes involved in this process is DNA polymerase, which catalyzes the formation of new DNA strands by adding complementary nucleotides to the existing template strand.

In a cell where replication bubbles form and RNA primers are present but no DNA replication takes place, the absence of DNA polymerase is the likely cause. DNA polymerase is responsible for elongating the RNA primers and synthesizing the new DNA strand during the replication process. Without this enzyme, the replication process cannot proceed, and DNA replication stalls.

RNA primers are short sequences of RNA that provide a starting point for DNA synthesis during replication. They are necessary because DNA polymerase can only add nucleotides to an existing strand and cannot initiate DNA synthesis on its own. Instead, it requires a primer, which is usually made of RNA, to start the process.

If DNA polymerase is missing or non-functional, the RNA primers cannot be extended, and DNA replication cannot occur. This can lead to various replication errors and the formation of incomplete DNA strands, ultimately affecting the stability and integrity of the cell's genetic material.

What is ridge push?

Answers

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?
