Answer:
The complementary DNA strand, according to the nucleotide sequence of the other strand is 3' - A C A T C G A C G C G C A - 5'
Explanation:
Each strand of DNA is made up of specific sequences of the four nucleotides present in this molecule, adenine, thymine, cytosine and guanine.
In double-stranded DNA, one strand complements the other —according to the complementarity of nitrogenous bases— where a purine, adenine and guanine, are joined with a pyrimidine, thymine and cytosine, respectively:
Adenine is complemented with Thymine. Guanine is complemented with Cytosine.According to this, the complementarity of the strands is:
5' - T G T A G C T G C G C G T - 3'
3' - A C A T C G A C G C G C A - 5'
The DNA strands remain linked by hydrogen bonds between their nitrogenous bases, until such time as they must be separated for transcription.

Answer:
Mitochondria:An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. Also known as the 'powerhouse of the cell.'
Cell wall:A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Nucleus:The positively charged central core of an atom, consisting of protons and neutrons and containing nearly all of the cell's mass.
Golgi bodies:The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.
ER (Endoplasmic Reticulum):A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell. Proteins and other molecules move through the endoplasmic reticulum. The outer surface of the endoplasmic reticulum can be smooth or rough.
Cell Membrane:The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Ribosomes:A sphere-shaped structure within the cytoplasm of a cell that is composed of RNA and protein and is the site of protein synthesis. Ribosomes are free in the cytoplasm and often attached to the membrane of the endoplasmic reticulum. Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains.
Cytoplasm:The cytoplasm provides a medium for the organelles to remain suspended. The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells. Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.

What is the elephant getting when the bond is broken in sucrose?
Answer:
Energy
Explanation:
The elephant is getting energy when the bond is broken into sucrose because as sucrose is broken down, it is hydrolized by enzymes sucrase which break the glycosidic bond and convert it to glucose and fructose in the upper gastrointestinal tracts. Glucose and fructose are then absorbed into the blood stream which glucose serve as energy source or stored as glycogen in the gastrointestinal tracts.

Explanation:
what physiological (body) factors might cause one to get more squeezes, in other words, to have
Fatigue? (Hint: consider how the reactants of aerobic respiration get to your musde cells)
Answer: Heart strength and healthy circulatory system
Explanation:
Fatigue is considered to be the state in which a person cannot maintain the level of performance or training expected. Muscles are able to obtain energy by aerobic or anaerobic respiration and both use carbohydrates or sugars, but only aerobics needs oxygen. To perform physical activity, the heart pumps more oxygen to the muscles that are performing the exercise. When the muscles work harder, the body consumes more oxygen and produces more carbon dioxide. So, aerobic respiration is a type of metabolism in which the organism uses energy from organic molecules, especially as glucose, where the carbon is oxidized by the oxygen. 36 molecules of ATP per glucose are produced during aerobic respiration.
During an effort, the energy produced by aerobic breathing is not enough and muscles need to produce a complementary energy through anaerobic respiration which provides less energy than aerobic respiration. This type of cellular respiration produces waste products that the cells must eliminate, for example lactic acid, which remains in the muscles producing pain after exercise. Only 2 molecules of ATP are produced for each glucose during anaerobic respiration.
Therefore, the heart strength is important because that organ is responsible for carrying oxygen to the muscles, which is needed to perform cellular respiration and get more energy to perform the exercise. And there must be also a healthy circulatory system that delivers that oxygen to every part of the body.

Review why carbon can form a variety of organic compounds in a variety of shapes.
Answer:
Carbon atoms readily bond with each other and can form long chains, branched molecules, and rings—an enormous variety of carbon backbones for organic molecules.
Explanation:
Carbon atoms easily connect with one another, allowing for the formation of lengthy chains, branching molecules, and rings—a vast array of carbon backbones for organic molecules.
What is carbon?Carbon is defined as the elements are distinguished by their capacity to form firmly bound chains that are sealed off by hydrogen atoms.
Carbon is also defined as an atomic number 6 chemical element with the symbol C.
Carbon is nonmetallic and tetravalent, with each atom releasing four electrons to form covalent chemical connections.
Carbon has the capacity to quickly form bonds with other atoms, which allows for greater flexibility in the shape and function of biomolecules such as DNA and RNA, which are required for the defining traits of life growth and replication.
An organic molecule is defined as a complex molecule composed mostly of carbon atoms that are bound with other elements and/or other carbon atoms.
Carbohydrate, lipids, nucleic acid and protein are some of the example of organic molecules.
Thus, carbon atoms easily connect with one another, allowing for the formation of lengthy chains, branching molecules, and rings—a vast array of carbon backbones for organic molecules.

Which of the following processes must occur for a forest ecosystem to recover after a wildlife? a)development b) evolution c)succession d) mutualism
Answer:
c) succession
Explanation:
Succession, in Ecology, refers to the series of changes that occurs to the structure of a biological community. Succession is of two types namely: primary and secondary succession. Primary succession is the colonization of an area for the first time by organisms called PIONEER SPECIES.
Secondary succession involves the recolonization of an area that has already been affected by environmental disturbances like hurricane, earthquake, wildfire etc. The already present SOIL makes it possible for certain organisms to colonize the affected area.
Therefore, succession (specifically secondary succession) is what must occur for a forest ecosystem to recover after a wildlife.
As lactose approaches the active site of lactase, as shown in the image, which of the following occurs first?
The lactose molecule is broken into glucose and galactose.
Lactase shifts to its lowest free energy level to allow lactose to enter the active site.
Lactose creates a microenvironment as it approaches lactase to promote binding.
Temporary bonding occurs between the active site and the substrate, causing a conformational change.
Answer:
There is no image attachment, however, this question can be answered based on general understanding of enzymes. The answer is:
Temporary bonding occurs between the active site and the substrate, causing a conformational change.
Explanation:
Enzymes are proteinous molecules that acts as catalyst in biochemical reactions by speeding up the rate of reactions. According to this question, lactase is an enzyme that acts on lactose sugar and breaks it down into its monomeric unit (glucose and galactose).
All enzymes possess an active site, with which they bind to their substrate. In this question, the lactose (substrate) approaches the active site of lactase (enzyme), what occurs first is that a temporary bonding occurs between the active site and the substrate, causing a conformational change in the shape of the enzyme.

Most fields that are irrigated year after year will eventually build up salt in the soil as water regularly evaporates and leaves some salt behind. One way farmers minimize this salt build up is to flood their fields every few years before planting. This flood water leaches out the salt in the soil. What advantages and disadvantages do you see in this approach?
Answer:
An advantage is that the salt will be washed out and a disadvantage is that it still leaves some salt behind
Explanation:
Irrigation is an agriculture practice which includes watering the cropland, this practice is advantageous as it washes the salt out of the soil however, some amount of salt still remains which affect the concentration of salts in soil.
What is irrigation?
Irrigation is the agricultural process which includes applying the controlled amounts of water to the land to assist the production of crops, as well as to grow the landscape plants and lawns in the agriculture lands. It may be known as watering in lawns. Agriculture which does not need irrigation but relies only up on the direct rainfall is referred to as rain-fed agriculture.
An advantage of the approach used in this case is that the salt will be washed out of the soil and a disadvantage of this approach is that it still leaves some salt behind in the soil which decreases the diffusion of water through roots due to increase in concentration of soil.

2. When diffusion has reached equilibrium, we say that
the net movement of the molecules is zero. Does this
mean these molecules below would stop moving?
Answer:
See Below.
Explanation:
The key word here is net. The net movement has reached zero when a system is in equilibrium but there are still motion's going back and forth due to statistics and just random brownian motion.
Think of it this way, if there are 100 people walking forwards in a crowd but 2 are moving against the crowd, the net movement is still forwards because the bulk of people are going in that direction. However, there are still 2 people moving against.
Same here, if we are talking about a diffusion, let's say in the case of osmosis, if most of the solute is moving across a membrane then we'd say its net direction is that way but that doesn't mean that there aren't processes happening in the other direction. Water molecules in osmosis mostly diffuse, chemically speaking (because you can say this biologically in a different way), from the probability of water molecules colliding with each other and passing the membrane so even if there is a net movement in a certain way their random motion can make them go to the other side just as well. If the fact that motion stops at equilibrium were the case a lot of systems, both chemical and biological, would not exist as we know it.
Think net = bulk NOT total or entire.
When the net movement is Zero at equilibrium ; An insignificant number of molecules are still moving below
When diffusion reaches equilibrium most of the molecules moving from the areas of higher concentration to areas of lower concentration will stop moving, but a negligible number of molecules will continue to move due to random Brownian motion.
When we say the net movement of molecules at equilibrium is zero it is because majority of the molecules have stopped moving and not all the molecules therefore there will be an insignificant movements of molecules still occuring.
Hence we can conclude that When the net movement is Zero at equilibrium ; An insignificant number of molecules are still moving below
