How many molecules of water are created when making a lipid?

Answers

Answer:

Three molecules

Explanation:

Since fats consist of three fatty acids and a glycerol, they are also called triacyclglycerols or triglycerides. Triacyclglycerols: Triacylglycerol is formed by the joining of three fatty acids to a glycerol backbone in a dehydration reaction. Three molecules of water are released in the process.

the nucleus

Explanation:

Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus.

Sunlight!

Explanation:

Place the following events in
the cell cycle in the proper
order:
a. Anaphase
b. Cytokinesis
C. G2
d. Telophase
e. G1
f. Prophase
8. S
h. Metaphase

Answers

Easy: G1 stage, G2 stage, S phase, prophase, metaphase, anaphase, telophase and lastly cytokinesis

The cell cycle in the correct order is G1, S, G2, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.

What is the cell cycle?

Prophase, metaphase, anaphase, and telophase are the four phases that a cell goes through. To form chromosomes, chromatin condenses (sister chromatids joined at the centromere).

In prophase, the chromosomes get shorter and thicker, in the center of the cell, during the metaphase, the chromosomes align. Chromatids separate during the anaphase process and travel to the opposing poles.

Telophase: Two nuclei are produced when nuclear envelopes have reformed around each chromosomal group.

Therefore, the cell spends the majority of its time in interphase, which is also when it grows, duplicates its chromosomes, and gets ready to divide.

when you move your hand up and down while holding on a jump rope, you make a wave. What is the medium

Answers

Answer:

The medium of the wave is the Rope.

Explanation:

This is because it is transverse wave and transverse wave need a medium to transfer energy and this is because in transverse wave,particles of the medium move in a direction that is perpendicular to the direction of the transverse wave. From the question, when you move you hand up and down, you make a wave and the direction of the wave is also up and down which is perpendicular to the direction of the wave.

Compare the reactants and products in the chemical equations below. Which statement best describes the relation between matter and energy?

Answers

Answer and Explanation:

Chemical reactions are very complex processes which include the collision of molecules. During the chemical reactions, bonds between the breakdown of the atom and transformed in new ways. The chemical compounds that react together during the chemical reactions are called reactants, shown on the left side of the equation. They are broken down during the reaction and used as the reaction progresses. The chemical compounds that are formed from the rearrangement and breakdown of the reactants are called products. The products are shown on the right side of the chemical equation. As compare to the reactants, the products are more stable molecules. For example, in the reaction between H2SO4 and Zn, these two chemicals are the reactants, while ZnSO4 and H2 are the chemical reaction products.

                                                Zn + H2SO4       ZnSO4 + H2

                                                 (Reactants)            (Products)

The matter is a material that everything is made of matter. A property that matter has is known as energy. The same quantity of matter can have a diverse quantity of energy. Both energy and matter are identical. For example, if we add some energy into an ice cube, it will turn into liquid. After that, if we add more energy, liquid will turns into steam.

Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twins, has just learned that they (the couple) are both heterozygous for both of these traits. As the couple's genetic counselor, the couple asks you what is the probability of having both of the twins be albino and have sickle-cell anemia.

Answers

Answer:

81/256

Explanation:

By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.  

Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.

The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis

Answers

Answer:

The color of light determines how effective chlorophyll pigment will be at absorbing light.

Explanation:

Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.

Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.

Which element has the least neutrons in the nucleus?
Aluminum
Nitrogen
Helium
Fluorine

Answers

Answer:heh

Explanation:

Aluminium , mass no = no of proton + neutron = 27

atomic no = no of proton = 13

no of neutron = 27 - 13 = 14

Nitrogen  , mass no = no of proton + neutron = 14

atomic no = no of proton = 7

no of neutron = 14 - 7 = 7

Helium   , mass no = no of proton + neutron = 4

atomic no = no of proton = 2

no of neutron = 4 - 2= 2

fluorine    , mass no = no of proton + neutron = 19

atomic no = no of proton = 9

no of neutron = 19-9 = 10

You plan to clone a guide RNA sequence into the pML104 plasmid because you want to engineer the construct in bacteria and later express it in yeast. Unfortunately, your lab does not have any available pML104. Your friend in the lab next door lets you borrow a related plasmid pML107, and you quickly start your experiment. Will it work? Briefly explain.

Answers

Answer:

Yes, the experiment will work.

Explanation:

The reason behind this is that plasmids are well known to be DNA vector carriers. These plasmids have the ability to bring about changes in DNA fragments into various microorganisms and reveal them. The two plasmids compose of the same genomic marker such as the antibiotic resistance gene found in URA3. However, plasmids are most commonly found in bacteria, but also in eukaryotic cells. Oftentimes, the gene composition in the plasmids enhances the bacteria with a vantage edge such as antibiotic resistance.

Hence, it is obvious that in both, the molecular regulation in terms of expression of genes is alike in properties. Similarly, the numbers of copies and molecular weight are also the same.

We can thereby conclude that, provided that there is a proper restriction site, another host that is up to standard for plasmid can be replaced for each other.
