Answer:
C. CH4 + 202 – CO2 + 2H20
Explanation:
CH4+O2-CO2+H20
The above equation represents combustion of methane to produce carbon-dioxide and water.
One carbon atom is present on the reactant side as well as on the product side. Four hydrogen atoms are present on the reactant side and two hydrogen atoms on product side. In order to balance this equation, we would multiply water molecule by two. Now there are four atoms of oxygen in the product side but only two on reactant side, so we will multiply oxygen molecule by two on the reactant side. Now the equation is balanced.
The balanced chemical equation is:
CH4+202-CO2+2H2O
This equation obeys the law of conservation of mass as the mass of the reactants is same as that of the products.
Answer:
C. CH4 + 202 – CO2 + 2H20

which muscle group relates best with the term midline?
The oblique is the muscle group that best relates with the term midline.
The anterolateral abdominal wall contains a muscle group in which there are flat muscles whose fibers originate in the posterolateral part, pass forward and become an aponeurosis towards the midline:
The external oblique muscle is the thickest and most superficial of the three muscles on the lateral wall of the abdomen.It follows an inferomedial direction and the muscle-tendon limit descends in such a way that, towards the midline and also below the height of the anterior superior iliac spine, it is completely transformed into an aponeurosis.The aponeurosis of the external oblique joins that of the internal oblique and passes in front of the rectus abdominis; its fibers intersect in the midline with those on the opposite side and contribute to the linea alba.
Therefore, we can conclude that the oblique is the muscle group that best relates with the term midline.

Which of the following would contain the largest concentration of digestive enzymes?
cell membrane
ribosome
chloroplast
lysosome
The LYSOSOME contains the largest concentration of digestive enzymes. This organelle has an internal acidic pH required for these enzymes to carry out their functions.
The lysosome is a eukaryotic membrane-bound organelle that contains different types of hydrolytic enzymes to degrade cellular components.
This organelle (lysosome) is part of the endomembrane system, which also includes the endoplasmic reticulum, Golgi apparatus, transport vesicles and nuclear envelope.
The main functions of the lysosomal enzymes include degradation and recycling of cellular byproducts, and metabolic roles.

Do rose plants grow faster in higher temperatures.
Answer: What roses are the best flowers is a non-scientific question.
Explanation: What flower is better is determined by personal opinion. I might think the red roses are prettier and you might think the white ones are. Where all the other questions can be tested all equally and it is not an opinion.
Answer:
why are roses the best flowers
What is the difference between El Nino and La Nina in science terms of climate?
Answer:
El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of it. El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
Hope this helps
Answer:
Well, El Niño(warmer environment) impacts weather systems around the world, while La Nina(cold environment) tends to have global climate affects opposite to El Nino.
In eukaryotes, gene expression is regulated mostly by _____.
Answer:
Gene expression in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription.
Explanation:
In eukaryotes, gene expression is regulated mostly by transcription factors.
What are transcription factors?Transcription factors are proteins that bind to DNA in the promoter region of a gene, and they play a critical role in controlling when and to what extent a gene is expressed.
They can either activate or repress gene expression by promoting or inhibiting the recruitment of RNA polymerase. Transcription factors are themselves regulated by a variety of signals, including hormones, growth factors, and other external cues, as well as by feedback loops and other regulatory mechanisms within the cell.
Ultimately, this complex interplay of factors allows eukaryotic cells to precisely control which genes are expressed, when they are expressed, and to what degree, enabling them to respond to changing internal and external environments.

In living organisms the cell
cycle is closely regulated.
What do you think will
happen if cell division is not
controlled?
Answer:
Explanation:
Disruption of normal regulation of the cell cycle can lead to diseases such as cancer. When the cell cycle proceeds without control, cells can divide without order and accumulate genetic errors that can lead to a cancerous tumor
The cell life cycle is controlled meaning that:
The reproduction of the cell is controlled.
The cell has a "programated death" meaning that at some point, all normal cells die.
If there is a problem with these (uncontrolled reproduction or cells that just not die) a tumor will appear.
Where the tumor is just a mass of these cells that reproduce uncontrolled and that don't die naturally.
So the thing that happens if cell division is not controlled, is that a tumor will appear.

Explain how the method of nutrition used by wild pine differs from the method of nutrition used by other organisms (animals)
Answer:
Most plants are auto trophic able to use sunlight as their primary source of energy,in a process called photosynthesis.This process enables them to turn carbon dioxide from the air into food,The carbon and oxygen which they need in order to build up their bodies ultimately comes from this carbon dioxide.
All animals are heterotrophs, which means that they cannot make their own food as plants do. Rather, animals must obtain the energy, carbon, hydrogen, oxygen, nitrogen, and minerals they need by consuming other living things. Animals are also animate, which means that they are capable of movement.
