Answer:
The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.
Explanation:
Potassium thiosulfate (K2S2O3) is used to remove any excess chlorine from fibers and fabrics that have been bleached with that gas. The reaction is K2S2O3 + 4Cl2+ 5H2O→2KHSO4 + 8HCl a. What mass of HCl will be produced at the same time that 45.0 g of KHSO4 is produced? (5 pst) b. What mass of Cl2 is consumed along with 2.20 x 1024 molecules of H2O? (5 pts)
Answer:
The correct answer is a) 48.16 grams of HCl will be produced, b) mass of chlorine consumed is 206 grams.
Explanation:
a) The reaction given is:
K₂S₂O₃ + 4Cl₂ + 5H₂O ⇒ 2KHSO₄ + 8HCl
Based on the given information, the mass of KHSO4 is 45 grams. The moles of KHSO4 can be determined by using the formula,
Moles = given mass/Molar mass
= 45/136.16
= 0.33 Moles of KHSO₄
From the reaction it can be seen that when 2 moles of KHSO₄ is produced, 8 moles of HCl is also produced. Therefore,
2 moles of KHSO₄ = 8 moles of HCl
So, moles of HCl will be,
Moles of HCl = 8 × 0.33/2
= 1.321 moles
Now the mass of HCl is,
Mass of HCl = Moles of HCl × Molar mass of HCl
= 1.321 × 36.46
= 48.16 grams of HCl
b) It is known that 1 mole is equal to 6.023 × 10²³ molecules
In the given case, the molecules of water is given, that is, 2.20 * 10²⁴ molecules. Now let us consider that the moles of water is x.
x mole of water = 2.20 × 10²⁴ /6.022 × 10²³
= 3.653 mole of H2O
From the reaction given, it can be seen that when 5 moles of water are consumed, 4 moles of chlorine are consumed.
5 moles of water = 4 moles of chlorine
3.653 moles H₂O = x moles of Cl₂
Moles of Cl₂ = 4 × 3.653 /5
= 2.906 moles Cl₂
Now the mass of Cl₂ determined as,
Mass of Cl₂ = moles of Cl₂ × Molar mass of Cl₂
= 2.906 × 70.9
= 206 grams

Which two structures are first to combine in translation?
1 and 4
3 and 4
1 and 2
2 and 3
The first two structures that combine during the process of translation are 1 and 4.
What is translation?The translation is a biological process during which the genetic codes in transcribed DNA, in the form of messenger RNA, are translated to their respective amino acids and joined together by peptide bonds to form proteins.
The steps involved in the translation process are:
mRNA binds to the small subunit of the ribosometRNA carrying methionine binds to the start codon on the mRNALarge ribosome subunit binds to complete the translation complex.In the image, mRNA is designated as 4 while tRNA is designated by 2. 1 is the ribosome while 3 is the synthesized protein.
Thus, the first two structure that binds is mRNA and tRNA. That will be 1 and 4.

Scientists describe the processes of photosynthesis and cellular respiration as "being interrelated". What is this statement most likely referring to?
A. The reactants of both processes are the same.
B. The products of both processes are the same.
C. The products of each process are the reactants to the other.
D. The processes occur at the same time.
Answer:
C. The products of each process are the reactants to the other.
The statement that photosynthesis and cellular respiration are interrelated means that the products of each process are the reactants to the other.
PHOTOSYNTHESIS:
Photosynthesis is the process whereby green plants obtain their food using energy from sunlight. Photosynthetic process combines carbon dioxide (CO2) and water (H2O) to form glucose and oxygen gas.CELLULAR RESPIRATION:
Cellular respiration is the process whereby living organisms obtain energy (ATP) by breaking down food molecules in their cells. Cellular respiration uses oxygen to breakdown glucose, thereby, forming carbon dioxide and water. Therefore, the statement that photosynthesis and cellular respiration are interrelated means that the products of each process are the reactants to the other.Learn more at: https://brainly.com/question/13721588?referrer=searchResults
How does decreasing the temperature when food is refrigerated slow decomposition and bacterial growth
Answer:
Low temperatures slow down chemical reactions, the action of enzymes, and delay or inhibit the growth and activity of microorganisms. The lower the temperature, the slower the chemical reactions, enzymatic action and bacterial growth will be.
Explanation:
Refrigeration consists of keeping the products at low temperatures, but above their freezing temperature. Refrigeration prevents the growth of microorganisms that can withstand temperatures above 45º C and many that can survive temperatures ranging from 15 to 45º C. If we lower the storage temperature of perishable foods, we will be able to significantly reduce the speed of reproduction of the vast majority of microorganisms, which cause decomposition and generate possible diseases in consumers. Refrigeration decelerates the metabolism of organic matter until it stops almost completely when we reach -18 ° C (international conservation standard for most frozen products), in addition to achieving partial or total inhibition of altering processes in food, such as certain enzymatic reactions or the metabolic degradation of proteins, thus delaying the decomposition of these.
according to newtons first law of motion a mass in motion remains in motion unless acted upon by some force true or false
According to Newton's first law of motion, the answer would be true.
The Newton's first law of motion states that a body will either continue to rest or in motion unless an external force acts on it.
For a body in rest, an external force would be needed to get it movingFor a moving body, an external force would be needed to increase or decrease its velocity or bring it to a rest.The body represents a mass. Hence, that a mass in motion would remains in motion unless acted upon by some force represents a version of Newton's first law of motion.

3. Where are the reproductive parts of an angiosperm located?
Answer:
The reproductive parts of an angiosperm are located in the flowers. A flower of an angiosperm usually consists of four whorls namely calyx, corolla, androecium and gynoecium.
Explanation:
Stamen includes anther (where pollen grains are produced) and filament, while carpel includes stigma, style, and ovary (where eggs are produced).
One line with red flowers and the other line with violet flowers. You carry out a monohybrid cross and find that all of the F1 offspring have violet flowers, while 97 of 400 F2 offspring have red flowers.
Explain the inheritance of flower colour in this plant species.
Answer:
See the answer below
Explanation:
The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.
Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r. The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:
RR x rr
F1 Rr Rr Rr Rr
phenotype ratio = all violet flower color
Rr x Rr
F2 RR Rr Rr rr
phenotype ratio = 3/4 violet flower color and 1/4 red flower color
97 red flower offspring out of 400 is approximately 1/4.
Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.
