This question must be considered carefully as in many cases we see arrows pointing from prey to predator, that is to say, who is eaten to actually eats it, this reflects how the energy flow among organisms, from producers to consumers and finally to decomposers. So taking this into consideration we can say that the correct answer is energy flow.

sand tiger shark embryos eat each other in the womb. dna testing recently revealed that the mystery of this baby shark cannibalism is due to embryos from different father competing to be born. if there are two embryos with the same father, they will eat all the other so they can both live, strengthen their bloodline. which of the following is the most likely outcome of this process over time?
Answers
In the womb, shark embryos devour one another, with the largest eating all but one of its siblings.
Is it true that sharks consume one another during pregnancy?Intrauterine cannibalism, or consuming the other fertilized or unfertilized eggs in the womb, is a habit of several species. Sand tiger sharks are the best-known utero cannibals. Despite having two uteri and laying several eggs, sand tiger sharks only have two pups per litter, one from each uterus.
Why do sand sharks devour their unborn siblings?According to a recent scientific study, sand tiger shark embryos attempt to eat their litter mates while still in the womb in order to become the embryo that will eventually give birth.

What is substitution in a mutation?Substitution is a type of mutation that involves the replacement of one nucleotide base in DNA with another.
It can be further categorized into three types: silent, missense, and nonsense. In a silent substitution, the change in the DNA base does not result in a change in the amino acid sequence of the protein that is being produced, because the genetic code is degenerate.

Answers
Answer:
a. Naked dna
f. nucleosome
e. solenoid
g. loop domain
d. chromatid
c. chromosomes
b. metaphase
Explanation:
The naked DNA consists of the DNA molecule not associated with proteins.
A nucleosome is an octamer of histone proteins (i.e., dimers of H2A, H2B, H3, H4) associated with DNA.
A solenoid is a chromatin fiber consisting of 30 nanometers (nm), it represents the secondary structure of the chromatin.
The chromatin fibers are organized into loops (300 nm) that represent the tertiary structure of the chromatin. These loops enable to package chromosome segments consisting of about 100 kilobases (kb).
The sister chromatids are two identical DNA-based structures that remain joined together by the centromere to form a single chromosome (700 nm).

Humans are susceptible to a wide range of diseases brought on by germs. Humans frequently contract bacterial illnesses such tetanus, TB, pneumonia, typhoid, and others.
Thus, Pathogenic bacteria are those that infect people and cause various diseases. The body's defense system's ability to produce innate immunity allows us to support the growth of numerous microorganisms.
Disease-causing bacteria can enter body fluids and tissues by outpacing the body's own defense mechanisms. Bacteria can either directly harm cells, release toxins, influence how cells function, or trigger an immunological reaction that harms the cells.
Diseases brought on by bacteria are called bacterial diseases. The human body contains a variety of microbes. Many of these are referred to be "good bacteria" because they don't lead to any diseases.

Different kinds of substances have different properties. Compare and contrast the electrical properties of salts, metals, and acids.
Answers
Salts, metals, and acids are three different types of substances exhibiting unique electrical properties.
Thus, salts are ionic compounds and exhibit electrical properties as they have both positively charged ions and negatively charged ions. They can dissociate in solution into their constituent ions to conduct electricity, but they can not conduct electricity in the solid state.
Like salts, metals also conduct electricity due to their free-moving electrons. They have high electrical conductivity and are used in electrical wiring and other applications. Acids release hydrogen ions when dissolved in water which allows them to conduct electricity because the hydrogen ions move freely and carry an electrical charge when acids are dissolved in water, thereby, exhibiting electrical properties.

(answer). an old growth forest with trees that are over 1,500 years old
Explanation:
these are the correct answers for the (Genetic Variation and Evolution Quick Check) 2022
The scenario that will decrease the genetic variation of a population is a population of birds suddenly decreasing their frequency of procreation.
What do you mean by Genetic variation?Genetic variations may be defined as the presence of differences in sequences of genes between individual organisms of a species.
Mutations always lead to an increase in the genetic diversity among individuals. While decreasing the rate of crossbreading may decline the rate of genetic diversity.
Therefore, the scenario that will decrease the genetic variation of a population is a population of birds suddenly decreasing their frequency of gender reproduction. So, the correct option is B.
