Answer:
Hello there!
Explanation:
Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.

Concrete has a density of 2.30 grams per centimeter cubed. What is the
mass of a concrete block in kilograms that is 1000.Ocm x 1000.Ocm x 15.0
cm? *
Answer:
Explanation:
density=2.30 g/cm^3
volume=1000.0 cm*1000.0 cm*15.0 cm=15000000
now we know that
d= m/v
therefore
m=d*v
m=2.30*15000000
m=34500000 g
now we have to convert grams into kg
1kg=1000 g
34500000 g=34500000/1000
34500000 g=34500 kg

What would happen to a phospholipid bilayer if the phosphates instantly lost their charge?
I
Answer:
The phosphate group is the negatively-charged and polar head present in the phospholipid bilayer.
The phosphate group is attracted to water in the intracellular fluid in the phospholipid bilayer and helps to maintain the fluidity of the bilayer. if phosphates instantly lost their charge then it will lose its attraction towards an intracellular fluid and phospholipid bilayer will lose its bilayer structure.

Based on this picture, how do you think a DNA molecule makes a copy of itself? (Hint: Look at the bottom two “rungs” of the ladder.)
The figure is not found here but DNA makes copies of itself by a semiconservative process. It is part of DNA replication.
What is DNA replication?DNA replication refers to the process by which a DNA molecule multiplies to produce two identical DNA molecules.
The DNA molecule is a double helix that may be considered a ladder, where pairs of nucleotides are the ladder's rungs.
DNA replication is semiconservative because the new DNA molecules have a new DNA strand and one original strand.

Why is biology so fun?
Answer:
Biology is a fascinating subject in and of itself. It has been my favorite subject to read about and study since I was an incredibly young child. Biology is unique in its complexity and the way living things interact with one another and with their environment. It is fascinating to consider that many of Earth's rocks and minerals came from living things. Chalk and limestone are the remains of small aquatic creatures, particularly shellfish, which died and fell to the seabed, where they were buried and compressed into rock. A limestone or chalk that has been subjected to elevated temperatures and pressures, for example, is metamorphosed into marble. The fact that flints started out as sponges is less well known. Mineralogy and geology on Earth would be quite different if there were no living things.

How does nondisjunction cause chromosome number disorders.
Answer:
Disorders of chromosome number include the duplication or loss of entire chromosomes, as well as changes in the number of complete sets of chromosomes. They are caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis.
Explanation:

Among the different forms of electromagnetic radiation emitted by the sun, which form is absorbed by plants for photosynthesis?.
Answer:
visible light is the em radiation absorbed by plants for the photosynthesis process.
The form of electromagnetic radiation that is absorbed by plants for photosynthesis is known as visible light. This is also known as photosynthetically active radiation (PAR).
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
Visible light lies in the visible spectrum of wavelength from 400 to 700 nm. This visible spectrum is a system where we study the properties of light. This spectrum defines the relationship between energy and wavelength.
Therefore, the visible light or visible spectrum is the form of electromagnetic radiation that is absorbed by plants for photosynthesis.

What is the environmental impact of allulose sugar?
Commercial allulose is most often derived from corn, long criticized as an industrial farmed monocrop that rapidly depletes both water supplies and soil health. Once the corn is grown and harvested, it gets fermented to pull out the fructose. From there, enzymes (often proprietarily created by various allulose manufacturers) are added to convert the fructose to allulose. Even if these manufactures are using solar power to offset carbon producing energy costs, and many are, with marketing surveys showing that 7 out of 10 people worldwide are looking to reduce their sugar intake, the fossil fuel energy required make the allulose to fill that need, is still likely to be significant. At this point in time, this eater is going to plan to reduce her sugar intake by just not having it. And when I do want something sweet, I’m going to stick to Maine maple syrup as my local sugar alternative.

Explanation:
Answer:
1.) Water; carbon dioxide
2.) Sugar; oxygen
3.) Pigment
4.) An electron
5.) ATP, NADPH, and oxygen
6.) NADP+
Explanation:
The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas. Molecules called pigments absorb energy from light. The main pigment in photosynthesis is called chlorophyll. Chlorophyll exists in several different forms in different organisms. Chlorophyll a is the main photosynthetic pigment found in land plants and algae. A photon of light energy travels until it reaches a molecule of chlorophyll. The photon causes an electron in the chlorophyll to become “excited.” The energy given to the electron allows it to break free from an atom of the chlorophyll molecule. Chlorophyll is therefore said to “donate” an electron. In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product.
