Which type of stem cell are plant cells like?
Answer:
Stem Cells in Plants. Stem cells function as a source of new cells to grow or replace specialised tissues. ... By creating genetic differences between cells of the same plant, scientists are able to track how the descendants of a single marked cell make up organs and tissues as the plant grows.
Explanation:
Parenchyma cells are the most common plant cells. They are found in the stem, the root, the inside of the leaf, and the pulp of the fruit.

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...

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).

Which enzyme is missing in a cell where replication bubbles form and RNA primers are present but no DNA replication takes place?
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 recycling? How does it help in management of hazardous waste?
Answer:
Recycling is the process of converting waste materials into new materials and objects.It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions.
When hazardous wastes are recycled, less energy is needed to obtain raw materials and to manufacture products. When energy demand decreases, fewer fossil fuels are burned and less GHGs are emitted into the atmosphere, which can help lessen the impacts of climate change and decrease air pollution.
Answer:
The process of converting waste materials into reusable material is called recycling.When hazardous wastes are recycled, less energy is needed to obtain raw materials and to manufacture products. ... This means less need for hazardous waste landfills and incinerators, as well as a decrease in energy used for those systems, which leads to less pollution

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 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.

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?

Jaden tells David that she knows that she also could stand to lose about 45 pounds, which she knows will also help increase her energy level. She was wondering if David had any tips on making healthy food choices. What might David tell Jaden?
Given what we know about the nutritional facts of each food type, we can confirm that David may tell Jaden to focus her diet on proteins, vegetables, and white meat if necessary while avoiding sources of fat.
Jaden should attempt to focus on creating a diet based on protein sources like whole eggs. Around this protein source, she may add vegetables or white meat. This is mostly to avoid eating saturated fats which are almost immediately stored by the body and thus will prevent weight loss.
Not all fats are bad, some examples of nonsaturated fats to include are:
