The correct answer is option B) negative.

The temperature in the body is controlled by the negative feedback. In the negative feedback regulation, the increase in a factor send the signals to reduce the effect. in the temperature regulation, the increase in the temperature causes the hypothalamus to release the signals, which lead to the decrease in the temperature.

What might happen if the rabbit population shrank due to disease
bonufazy [111]

Answer:

The survival of many carnivore species, including the Iberian lynx and fox, is contingent on them getting their key prey: the rabbit (Oryctolagus cuniculus). But a Spanish-Argentinean team of researchers has investigated how the collapse of the rabbit population in the late 1980s, triggered by viral haemorrhagic disease (VHD), has adversely impacted the lives of certain carnivores in Doñana National Park, a national park and wildlife refuge in south-western Spain. The findings, published in the journal Basic and Applied Ecology, indicate that the population decline for the most part has affected the lynx; this medium-sized wildcat cannot hunt other prey.

Not one of the ways that bacteria have adapted to become resistant to antimicrobial agents.
Dominik [7]

Answer:

Explanation:

An antimicrobial agent is a natural or synthetic chemical that kills or inhibits the growth of microorganisms. Bacteria have a mechanism of transferring genomic material called <em>horizontal gene transfer</em><em>, the movement of genes between cells that are not direct descendants of one another</em>. Horizontal gene transfer allows cells to quickly acquire new characteristics and drives metabolic diversity. <u>One of the characteristics usually acquired is the resistance to antibiotics</u>.

Three mechanisms of genetic exchange are known in prokaryotes:

(1) transformation, in which free DNA released from one cell is taken up by another; (2) transduction, in which DNA transfer is mediated by a virus; and (3) conjugation, in which DNA transfer requires cell-to-cell contact and a conjugative plasmid in the donor cell.

Examples of genes transferred by transducing bacteriophages include multiple antibiotic resistance genes among strains of <em>Salmonella enterica </em>serovar <em>Typhimurium</em>, Shiga-like toxin genes in <em>Escherichia coli</em>, virulence factors in <em>Vibrio cholerae</em>, and genes encoding photosynthetic proteins in cyanobacteria.

Conjugative plasmids use a mechanism to transfer copies of themselves and the genes they encode, such as those for antibiotic resistance, to new host cells.

In a good experimental design, the part of the experiment that is intentionally changed is the
Vika [28.1K]

Constants never change.

Controls typically don't change or they are done by standard means

(like in an experiment where you water plants with sodas, the plant you use water with is the control)

Dependent variables are the outcome of the experiment. This is the result of changing something.

Independent variables are what you are testing. A independent variable is something that is  intentionally altered.

easy way to remember it is that dependent variables depend on what other variables are. so you cant change a dependent variable, but you can change the other variables.

_______________ is an interdisciplinary field of study concerned with the genetic bases of individual differences in behavior an
saul85 [17]

Answer:

Behavioral Genetics

Explanation:

The subject of Behavioral Genetics is usually defined as the study of genetic and environmental effects that occurs in the behaviors. This is important because by studying these effects of genetic influences, a large number of information can be obtained regarding how the environment controls the behavioral influence. This subject is commonly known as the Psycho-genetics. In simple words, this studies the interaction between the environment and the heredity, thereby affecting the behavior.
