An enzyme known as rubisco enables plants to use large amounts of
carbon dioxide. This enzyme is most likely active in the
O (1) nucleus
O (2) vacuoles
O (3) mitochondria
O (4) chloroplasts
Answers
The enzyme rubisco is most likely active in the chloroplasts.
• In the chloroplasts of the plants, the enzyme rubisco is present.
• It takes part in fixing atmospheric carbon dioxide at the time of photosynthesis and in oxygenation of the resulting compound at the time of photorespiration.
• Rubisco is the name given to the enzyme ribulose-1,5-bisphosphate, which catalyzes the carbon dioxide entry into the photosynthetic metabolism, monitors the pool sizes of essential photosynthetic intermediates, and provides acceptor molecules, which consume the products of the light reactions of photosynthesis.
Thus, option 4, that is, chloroplasts is correct.

photosynthesis
Answers
Answer:
CO2 + H2O ---SUNLIGHT--------> C6H12O6 + O2
Explanation:
In the process of photosynthesis, carbondioxide reacts with water molecules in the presence of sunlight forming glucose molecules and oxygen gas. The carbondioxide enters the plant body through small openings called stomata, these stomata opens when there is sunlight whereas water enters the plant body through roots from the soil and reaches to the leaves. In leaves both combine produces glucose which can be stored in different parts of the body and some oxygen is used by the plants in the process of respiration and extra is released through stomata.

Which celestial objects are formed mostly of the elements hydrogen and helium?
gas giantsgas giants , ,
rocky planetsrocky planets , ,
asteroidsasteroids , ,
dwarf planets
Answers
with 75% of their mass being hydrogen and 25% helium.
Celestial objects that are formed mostly of the elements hydrogen and helium are gas giants and dwarf planets. Gas giants are large planets, such as Jupiter and Saturn, which are composed primarily of hydrogen and helium.
What is the reason of calling them Jovian planets ?These planets are also known as Jovian planets, and they are much larger than the terrestrial planets, such as Earth, that are made up of rock and metal. Gas giants have no solid surface and are composed mostly of gas and liquid.
Dwarf planets are smaller than gas giants and are made up of a combination of rock and ice. These objects are too small to be considered full-fledged planets, but they still have characteristics of planets such as an atmosphere, moons, and an orbit around the sun.
Although these objects are composed of different materials than gas giants, they still contain significant amounts of hydrogen and helium. In contrast, rocky planets and asteroids are composed of materials such as rock, metal, and ice. Rocky planets, such as Earth, are composed mostly of iron, silicon, magnesium, and other elements
Hence, . Asteroids are small, rocky objects that are found in the asteroid belt between Mars and Jupiter. These objects are composed of rock, metal, and ice, and contain very little hydrogen and helium.

Describe at least three large - scale detrimental consequences of rising temperatures
Answers
Answer:
En primer lugar hay que decir que en contra de lo que puedan pensar muchas personas, el aumento de las temperaturas es una realidad. De hecho, no hay más que ver algunos datos comparativos para darse cuenta, por ejemplo, de que la temperatura de los polos ha aumentado considerablemente en el último siglo.
En primer lugar y por encima de todo tenemos que tener muy claro que el hábitat está cambiando de una manera abismal por lo que la vida del ser humano en La Tierra cada vez es más complicada. Si a esto le unimos el hecho de que nosotros no somos el único ser vivo cuya vida se complica, podemos concluir que muchas especies no serán capaces de adaptarse a estos cambios por lo que morirán. Un cambio que se puede llevar consigo gran parte de las cosechas que existen a día de hoy.
Una serie de consecuencias que lejos de ser catastróficas son más que plausibles. Es cierto que del mismo modo que esta situación se puede dar, no es menos cierto que todavía hay opciones de revertir la situación. La pregunta, sin embargo, es saber si el ser humano está dispuesto a ello.

When H. pylori was first discovered, researchers doubted the finding. It was thought that the acidic environment of the stomach was too hostile for microbes to thrive. Newer research using genetic analysis and culture techniques has revealed that there is a diverse gastric microbiota. Of the options below, what is the only one that does not involve genetic analyses?
A. Sequencing approaches have shown that the normal microbiota includes Archaea and provide mechanisms for studying their distribution.
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
C. Knowledge of the microbiota from sequencing efforts has been used to improve cultivation techniques.
D. Genetic analyses have been used to examine the dominant species in different individuals, showing that it varies from one individual to another.
Answers
Answer:
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
Explanation:
Genetic analyzes are tests that try to identify the genetic composition of a living being, being able to analyze the DNA in a profound way and obtaining crucial information about the organism. The most common way to carry out a genetic analysis is through the sequencing of genes, since they are segments of DNA molecules. Therefore, we can conclude that among all the response options presented above, all that refer to the sequencing of genes should be discarded. Thus, we can see that option B is the correct option, since the analysis of growth rates does not involve a genetic analysis.

Stem cells undergo a process known as differentiation in order to become specialized. Specialized cells do not revert back into their undifferentiated form once they have matured. Nucleic acids play a role in the process of differentiation. Which statements describe the relationship between nucleic acids and differentiation? Select ALL that apply.
A) Genes within the genome tend to remain inactivated until their gene products are needed.
B) Once they are differentiated, cells contain additional DNA that programs the cells to be specialized.
C) All cells in an organism, whether differentiated of not, contain a complete genome with the exact same genes. Hindi
D) Stem cells remove part of their genome once they are differentiated so that unnecessary genes cannot be expressed.
E) Transcription factors are present in certain cells that cause specific genes to be transcribed in differentiated cells.
Answers
A
C
E
(Trust me)
Explanation:
The differentiated cell has specific transcription factors that are present in the cell and cause specific genes to be transcribed. Option E is the correct answer.
What is cell specification?Cell specification is the process by which a cell determines its fate. After specification, a cell's gene pattern changes. Some genes that are present in euchromatin regions are expressed, and as a result, this cell expresses specific proteins and RNA.
After the zygote is formed, it undergoes a cleavage process to form multiple cells by mitosis. The cells then specify and receive their fate, such as some converting into nervous cells, others into epithelial cells, and still others into blood cells.
This change in structure and function is due to the expression of special genes in DNA. Though all cells have the same genetic content, some genes are present in euchromatin regions and some genes are present in heterochromatin regions. Genes of euchromatin are expressed.
Hence, option E is the correct answer, as the cell produced specific transcription factors.

Explanation:
if not I'm sorry
The zygote is basically an example of totipotent cell in humans. The correct option is B.
What is totipotent cell?Cell potency refers to a cell's capacity to distinguish into various types of cells. The greater a cell's potency, the more cell types it can differentiate into.
A totipotent cell is a single cell that, when given the proper motherly assistance, can give rise to a new organism.
A totipotent cell is one that can generate all extraembryonic tissues, as well as all body tissues and the germline.
The term "totipotent" refers to a cell that has the ability to split and produce all differentiated body cells, both embryonic and extraembryonic.
Zygotes and spores are instances of totipotent cells in animals.
Thus, the correct option is B.
