hydrogen gas + oxygen gas =
water. what is the product of the reaction
Answer:
Water
Explanation:
In chemical reactions, the atoms in the reactants are rearranged to form the products.
Reactants vs. Products
The reactants in a chemical reaction are the substances that you began with. The products are the result of the reaction.
For example, in the question, you are given hydrogen and oxygen. Then, through a chemical reaction, water is created. The reactants (hydrogen and oxygen) are the compounds that are changing to create the product (water).
Finding the Products
The order that a chemical reaction is written is important. Unlike equations in math, you cannot arbitrarily change the left and right. The left side of a reaction will always contain the reactants, while the right side has the products. Since water is on the right, water is the product.
State two contributions each, for any five areas of agriculture in agricultural development.
Answer:
As the non-agricultural sectors develop, their dependence on agriculture for other contributions like that of capital, labour, raw material etc., is reduced. However, dependence of the non-agricultural sectors on agriculture for provision of wage goods will be as strong as ever unless, of course, new scientific innovations also result in the production of perfect synthetic substitutes for food grains.

Which set of membrane proteins in the figure depicts an interaction between two separate cells?.
Some integral proteins serve as cell recognition or surface identity proteins, which mark a cell’s identity so that it can be recognized by other cells. Some integral proteins act as enzymes, or in cell adhesion, between neighboring cells.
Integral proteins are a set of membrane proteins that depict an interaction between two separate cells and the lipid bilayer forms the basis of the cell membrane, but it is peppered throughout with various proteins. Two different types of proteins that are commonly associated with the cell membrane are the integral protein and peripheral protein.
As its name suggests, an integral protein is a protein that is embedded in the membrane. Many different types of integral proteins exist, each with different functions. For example, an integral protein that extends an opening through the membrane for ions to enter or exit the cell is known as a channel protein.
Peripheral proteins are typically found on the inner or outer surface of the lipid bilayer but can also be attached to the internal or external surface of an integral protein.

Geologists have special tools to help them learn more about how energy is carried in the lithosphere. If a geologist observed that the speed of seismic waves in an area was increasing, what might he infer? a Tectonic plates in the lithosphere have moved. b There is water underground in the area. c The lithosphere is mainly made up of solid rock. d The temperature of the inner core has cooled somewhat.
Answer:
The answer is option A "Tectonic plates in the lithosphere have moved."
Explanation:
Despite the fact that the innovation doesn't exist to go into the entirety of Earth's layers, researchers can even now become familiar with an incredible arrangement about Earth's structure through seismic waves.
Seismic waves are vibrations in the earth that send energy and happen during seismic movement, for example, quakes, volcanic emissions, and even man-made blasts. There are two sorts of seismic waves, essential waves and optional waves. Essential waves, otherwise called P waves or weight waves, are longitudinal pressure waves like the movement of a smooth . Auxiliary waves, or S waves, are more slow than P waves. The movement of auxiliary waves is opposite to the heading of the wave travel, like the movement of energetically shaking a rope

There are two types of data:
1) Qualitative data
2) Quantitative data
These are further classified into four types of data: nominal, discrete, ordinal, continuous.
Quantitative data type tries to quantify things and does by considering numerical values that make it countable in nature. It includes statistical data analysis. These type of data are also known as "Numerical data". It answers the questions like, "how much", "how many", "how often".
Quantitative data can be used for statistical manipulation. These data can be represented on wide variety of graphs and charts such as bar graphs, pie charts, line graphs, histograms, etc.
They can be further divided into two parts: discrete and continuous.

mutants of arabidopsis with alterations in seed lipid fatty acid composition theoretical and applied genetics
The discussion of mutants of arabidopsis with alterations in seed lipid fatty acid composition theoretical and applied genetics is written in below paragraph-
By analyzing the fatty acid composition of samples of seed from 3,000 mutagenized lines, a rich variety of mutant Arabidopsis with different seed lipid compositions was discovered. Defects in the elongation of 18-1 to 20-1, desaturation of 18-1 to 18-2, and desaturation of 18-2 to 18-3 were caused by a series of mutations that were found. The wild type showed partial dominance over the mutant allele in each of these instances. These findings, in addition to findings from other studies, indicate a significant role for gene dosage in influencing the fatty acid content of seed lipids. A mutation that increased the accumulation of 183 was also discovered.
A broad variety of mutant Arabidopsis with various seed lipid compositions was found by examining the fatty acid composition of seed samples from 3,000 mutagenized lines. A number of mutations were discovered that were responsible for defects in the desaturation of 18-1 to 18-2, 18-1 to 18-2, and 18-2 to 18-3. In each of these cases, the mutant allele was somewhat dominant over the natural type. These results, together with those from previous studies, point to a significant role for gene dosage in affecting the fatty acid composition of seed lipids. Additionally, a mutation that increased the accumulation of 183 was found.

How do positive and negative feedback loops differ?
a Positive feedback loops increase the amount of positively charged ions, while negative feedback loops increase the amount of negatively charged ions.
b There is no difference; they both have similar functions.
c Positive feedback loops are good for the cells, while negative feedback loops are harmful to cells.
d Positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal.
Answer:
Positive and negative feedback differs in that positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal (option d).
Explanation:
Feedback is a process that, applied to biological systems, allows for the changes needed to maintain homeostasis.
Negative feedback loop occurs when a stimulus is presented, producing a change in the body, so the response is to stop the change that is occurring. It is the most frequent type of feedback and has the greatest impact on homeostasis. An example of negative feedback is a decrease in body temperature through sweating. Positive feedback loop occurs when the stimulus produces a change and promotes a response that reinforces that change. The classic example of positive feedback is the secretion of oxytocin, promoted by uterine contractions, whose effect is to increase those contractions, allowing labor.In summary, positive feedback loop acts by increasing an action or signal in the body, while the negative feedback loop reduces or stops the action or signal that occurs.
Answer:
D is correct
Positive feedback loops increase the initial signal, while negative feedback loops decrease the original signal.
