Answer:
The correct answer is option A. Seabirds: mutualism
Jellyfish: predation
Copepods: parasitism
Explanation:
In this given example sunfish have three different relationships with all three organisms that are related to it tat are seabird, jellyfish, and copepods.
With seabirds, sunfish shows mutualism as they both get benefitted from their relationship in which seabirds feed on copepods and sunfish get rid of their parasite.
With jellyfish, sunfish feed on the jellyfish mainly which suggests that they are predator and jellyfish are prey and their relationship is of predation.
With copepods, copepods bury their heads on the soft tissue of the sunfish so they are parasite on the sunfish that is example of the parasitism
Answer:
A. Seabirds: mutualism

Which best explains how to oxygen Atoms,
each with six valence electrons can bond with each other?
Answers
Explanation:
Two oxygen atoms bonds with each other via covalent bonding.
In the formation of covalent bonds, two atoms with little to no electronegativity difference combines by sharing of the valence electrons. This why homonuclear molecules can be formed.
Two atoms of the same kind having zero electronegativity difference forms this covalent bonds. There is equal sharing of electron pair between the atoms and there is no electrostatic charge on the molecule.For the oxygen atom with 6 valence electrons;
two electrons are shared by each atoms to make a complete octet and a stable molecule.

Photosynthesis is carried out by plants, alga, and blue green bacteria. It takes the energy from the sun and puts it into the bonds of sugar molecules. Photosynthesis only stores energy in food (glucose), we use respiration to get the energy out of food.
Respiration: Process that takes energy from sugar molecules and places it in molecules of ATP
Aerobic Respiration requires oxygen, and yeilds more ATP for a molecule of sugar than anaerobic (no oxygen) respiration.
Photosynthesis and Aeorbic Respiration are opposite reactions. They are also important in cycling oxygen, carbon, hydrogem and water through the environment.

What would be the main problem with reproduction if meiosis did not take place to form sex cells?
Answers
Answer:
Fertilization would result in a zygote with twice as many chromosomes as the parents.
Explanation:
Meiosis creates four haploid cells from a diploid parent cell. These haploid cells are the sex cells - sperm cells and egg cells.
Since these cells are haploid (containing 23 chromosomes, half the amount of chromosomes as the parent diploid cells), when they fuse during fertilization, they form a diploid zygote containing 46 chromosomes.
Answer:
B) Fertilization would result in a zygote with half as many chromosomes as the parents.

Fungi have cell walls characteristic which fungi share with plants but not animals, hence option C is correct.
What are the characteristics of fungi?When compared to animals, fungi need prepared organic substances for energy because they are heterotrophic organisms without chloroplasts.
Fungi are eukaryotic organisms, just like plants, and have nuclei in each of their cells. Like plants, fungi lack a cell wall and vacuoles, however, they do have a material called chitin in their cell walls that plants do not. In numerous important respects, fungi are also similar to animals.
Eukaryotic, non-vascular, immobile, heterotrophic creatures are fungi. They could be filamentous or unicellular and spread spores to reproduce. The phenomena of generational alternation are seen in fungi.
Therefore, in comparison to plants, fungi have vacuoles and a cell wall.

Answer:
Family members have a similar genetic make-up that may make them predisposed to cancer.
Explanation:
Variation in certain genes can increase the risk of developing certain cancers. This is why certain cancers run in families. There are lots of examples where the risk factor is small, but in some cases, the risk factor is very large.
For example, mutations in BRCA1 are very highly linked to the risk of breast cancer. As a result, many women with mutations in this gene opt to get a mastectomy to reduce their chances of developing breast cancer.
what is the difference in potential between two charges called
Answers
Answer:
volt
Explanation:
The potential difference is expressed in volt (V). The potential difference between two points is said to be 1 volt if the work is done in moving 1-coulomb charge from one point to other is 1 joule. 1 volt= 1 joule/ 1 coulomb Unit for measuring the potential difference is volt and instrument used for measuring potential difference is a voltmeter.
Answer:
Its potential is taken as zero potential. Thus the positively charged conductor has more positive potential than the earth. A negatively charged conductor has negative potential less than that of the earth. The electric potential difference between two points in an electric circuit is the work done in moving a unit positive charge from one point to the other.
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.
Answers
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.

Brings into question this conclusion
Neutral observation
Answers
Answer:
See explanation
Explanation:
I will try to explain each point mentioned to the best of my ability.
The dissolution of calcium chloride in water is endothermic hence more solute dissolves as the temperature increases. When the solution cools, the solubility of the solid also decreases with decreasing temperature hence the solid reappears.
When soda is heated, carbon dioxide gas is evolved thereby decreasing the amount of dissolved carbon dioxide.
Let me state that increase in volume of solvent increases the amount of solute that can dissolve in it. This is why 250ml volume of solvent can dissolve more solute than 100ml of solvent.
Also, temperature is an important factor when discussing the solubility of a solute. This is why the temperature at which a certain value of solubility is quoted must be indicated. For solids, solubility increases with increase in temperature.
Lastly, the solubility of sodium chloride is independent of temperature. This is clearly seen by plotting a solubility curve.
