A population of salamanders lives near a stream. A severe drought dries up the flow of the stream. What is this effect on the salamander population called? Group of answer choices: emigration limiting factor immigration biotic factor
Answer:
limiting factor
Explanation:
In an ecosystem, certain factors hinder the growth or abundance of the population of organisms. These factors are called LIMITING FACTORS. Limiting factors, which can be biotic, food, drought, predation, disease etc, are factors that inhibits a population of organism from becoming enlarged. There are two types of limiting factors viz: density dependent (depends on size) and density independent (not dependent on size).
This is the case of a drought that dries up the stream that inhabits a population of salamanders. The drought causes the unavailability of water, which will ultimately have an effect on the growth of the salamander population. Hence, the DROUGHT is considered a LIMITING FACTOR.

Not one of the ways that bacteria have adapted to become resistant to antimicrobial agents.
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 horizontal gene transfer, the movement of genes between cells that are not direct descendants of one another. Horizontal gene transfer allows cells to quickly acquire new characteristics and drives metabolic diversity. One of the characteristics usually acquired is the resistance to antibiotics.
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 Salmonella enterica serovar Typhimurium, Shiga-like toxin genes in Escherichia coli, virulence factors in Vibrio cholerae, 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 an experiment, the thing you compare your experimental results to is called the
the thing you compare your experimental results to is called the control group.
What do you mean by control group?Control group is the standard to which comparisons are made in an experiment. Many experiments are designed to include a control group and one or more experimental groups.
Moreover, some experiments use multiple control groups to gather more information and improve the accuracy of results. For example, many medical studies include positive, negative and placebo.
The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group.

Molecule that contains the information for the growth and functioning of the cell
Answer:
Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature. These cells cooperate with other specialized cells and become the building blocks of large multicellular organisms, such as humans and other animals. Although cells are much larger than atoms, they are still very small. The smallest known cells are a group of tiny bacteria called mycoplasmas; some of these single-celled organisms are spheres as small as 0.2 μm in diameter (1μm = about 0.000039 inch), with a total mass of 10−14 gram—equal to that of 8,000,000,000 hydrogen atoms. Cells of humans typically have a mass 400,000 times larger than the mass of a single mycoplasma bacterium, but even human cells are only about 20 μm across. It would require a sheet of about 10,000 human cells to cover the head of a pin, and each human organism is composed of more than 30,000,000,000,000 cells.

The phase sequential mask is certified for use up to_____feet.
Answer:
The correct answer is "40,000".
Explanation:
According to the Federal Aviation Administration, the phase sequential mask is certified for use up to 40,000 feet, because above this level the pressure will not allow the lungs to take enough oxygen. A specialized system such as pressure demand is necessary in order to fly to higher altitudes. These systems provide oxygen under positive pressure conditions.
Which of the following E. coli proteins is responsible for advancement of the mRNA during translation?A. EF-G
B. IF2
C. IF1
D. EF-Tu
E. None of these.
Answer:
The correct answer is option A. "EF-G"
Explanation:
As its name implies, the elongation factor (EF-G) of E. coli is one vital protein that participates during the elongation phase of translocation. EF-G catalyzes the GTP-dependent ribosomal translocation step, which allows the ribosome to change from its pre-translocational to the post-translocational state, moving the process from the P to the E site of the ribosome.
How are tigers and goldfish share the same phylum?

See the answer below
Explanation:
Tigers and goldsih share the same phyllum because they both posses the basic characteristics of animals in the phyllum chordata. These characteristics include;
Possession of notochord. The notochord is a rod-like structure that serves supportive functions and develops into the vertebral column in some group of chaordates.Posession of post-anail tails which is an extension of the posterior end of the of the body.Possession of dorsal, hollow nerve chord which eventually forms the brain and the central nervous system.Possession of pharyngeal gill-slits, an opening that develops into gill arches in golfishes and jaws in tigers.A blow to the head may cause diabetes insipidus by ______. A blow to the head may cause diabetes insipidus by ______. triggering the hypersecretion of hypothalamic-inhibiting hormones triggering the hyposecretion of hypothalamic-inhibiting hormones interfering with the normal transmission of nerve impulses to the posterior pituitary interfering with the normal transmission of nerve impulses from the posterior pituitary
Answer: interfering with the normal transmission of nerve impulses to the posterior pituitary
Explanation: A blow to the head may cause diabetes insipidus by interfering with the normal transmission of nerve impulses to the posterior pituitary. Interfering with the normal transmission of ADH (antidiuretic hormone) to the posterior pituitary is done via the axons of the hypothalamic neurons. The disease is a rare one, characterized by the excretion of large amounts of severely diluted urine which cannot be reduced when fluid intake is reduced. It is generally related to a tumor or an insult to the pituitary gland, where the hormonal signals it gives to the kidneys break down, and the kidneys do not conserve water, but express the water as urine.
Explain why ecological succession occurs.
Ecological succession occurs due to the changes in physical environment and population of species. In an ecosystem, a species requires a particular set of environmental conditions under which they grow and reproduce.
Ecological succession occurs due to the changes in physical environment and population of species. In an ecosystem, a species requires a particular set of environmental conditions under which they grow and reproduce.
What is an Ecological succession?Ecological succession is the process by which plant communities develop over a period of time on the land where there was no vegetation.
The succession begins with a pioneer species such as lichens, some fungi species. Species such as lichen begins to secrete acids that begin to break the barren land into small particles.
The small particles mix with lichen remains and starts soil formation.
Thus, Ecological succession occurs due to the changes in physical environment and population of species.

Which of the following processes do not take place in the mitochondria? a) citric acid cycle b) conversion of pyruvate to activated acetyl groups c) oxidation of fatty acids to acetyl CoA d) glycogen breakdown
Answer:
D
Explanation:
The breaking down of glycogen-glycogenolysis takes place in the cytosol of cells of the liver and muscles.it is the compensatory process for providing glucose depleted cells with extra glucose. It is the opposite of Glucogengenesis the formation of glycogen in cells.
it involves the activities of enzymes glycogen phosphorylase which catalysis the removal of alpha1-4glycosidic bonds from the glycogen molecules.Thus freeing the glucose molecules from the glycogen while retaining the 1-6 glycosidic bonds.
Its stimulation is by epinephrine hormone.while the hormones glucagon from the pancreas control its release into the blood stream,Thus the low levels of glucose in the blood stream caused glucagon to initiate the breakdown of glycogen in the liver and muscles down to glucose.As the level of this rise in the blood stream Insulin stimulates the entry of the glucose into the cells reducing the levels of blood glucose,inhibiting glucagon levels ,and therefore stopping Glycogenolysis.
