How do ecologists describe populations? (4 things)
Answer:
The description about population according ecologists is as follows:
Explanation:
Thre are various ecological aspects studied by the ecologist in the ecosystem and one of them is Population ecology. According the ecolgists all member or total individuals of a particular species present in an ecological community is Population.
There are different asppects of the population ecology that helps in the understanding the population such as size of population, growth of population nter and intra- intractions of population. All these aspects are part of population ecology studied by the ecologists.
Staph infections caused by the bacterium staphylococcus aureus are increasing in frequency and are more difficult to treat with antibiotics many staph infections are now caused by mrsa and methicllian resistant strain of s aureus. What explains the more widespread phenomenon of mrsa prevalence in staph infections
Answer:
This question lacks options, options are: A) Vaccines for MRSA have become not effective because of changes to human immune systems. B) The presence of antibiotics induced the bacterial genomes to mutate and develop resistance to the drug. C) Decreased hospital sanitation practices to save money have resulted in increased presence of resistant staph infections. D) Selective pressures by excessive antibiotic use have increased the frequency of resistant strains of S. aureus over the last few decades.The correct answer is D.
Explanation:
The susceptibility of the various germs has varied greatly in recent years. Strains that had been consistently susceptible to all antimicrobial agents for decades have now developed resistance to these classic therapies, they have the ability to rapidly develop resistance to the newer antimicrobials. Methicillin Resistant Staphylococci (MRSA) is a clear example of this situation. The mechanism that confers resistance to methicillin is complex, since the bacterium has generated a genetic variation, which is encoded in the mecA gene, by which it modifies the structure of its penicillin-binding or binding protein (PBP2a), This prevents methicillin from adhering to the place where it is going to exert the action of blocking the transpeptidase enzyme (whose function in the bacterial life cycle is to synthesize the bacterial wall).Resistance to methicillin in strains of S. aureus is a growing problem worldwide, and staphylococcus gold is an agent that spreads easily and the behavior of the process is aggressive, with which this agent not only carries resistance to methicillin , but rather all ß-lactam antibiotics, including cephalosporins and carbapenem.
Answer:
D. Selective pressures by excessive antibiotic use have increased the frequency of resistant strains of S. aureus over the last few decades

A mutation that could be inherited by offspring would result from-?
Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.
Explanation:
A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.
What is mutation?Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.
As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.
Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.
Thus, the correct option is D.

What is the formula for speed of a wave?
Answer:
Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known
Explanation:

D.
Chromosomes are arranged in 20 distinct pairs in the human body.
Please select the best answer from the choices provided
A
B
C
D
Answer:
B. Chromosomes are threadlike structures that carry genetic information
Explanation:
Normally developed humans carry about 46 chromosomes in each cell, so A is false.
The numver of chromosomes is equal from the mother and the father, so C is false.
Chromosomes are arranged in 23 distinct pairs, so D is false.
The statement that best describes chromosomes is: Chromosomes are the threadlike structures that carry the genetic information.
What is a chromosome?It is a structure that is present in both prokaryotes and eukaryotes and is composed of nucleic acid (DNA) and proteins. It is responsible for genetic information.
Facts about chromosomes:Humans have 46 chromosomes in all somatic cells, and the reproductive cells except in the sperm and ova, which are haploid with 23 chromosomes only. Humans receive one set of 23 chromosomes from their mother and the other set from their father.Chromosomes are arranged in 23 distinct pairs in the human body.Hence, option b) is the correct option.

What are the two main principles of Mendelian genetics?
Answer:
The key principles of Mendelian inheritance are summed up by Mendel's three laws: the Law of Independent Assortment, Law of Dominance, and Law of Segregation
Explanation:
__________
Answer:
Mendel's observations from these experiments can be summarized in two principles: According to the principle of segregation, for any particular trait, the pair of alleles of each parent separate and only one allele passes from each parent on to an offspring. Which allele in a parent's pair of alleles is inherited is a matter of chance.

Which level of organization is represented by the skeleton of the snake?
А.organ
B.organism
C.tissue system
D.organ system
Tissue system, enables the snake to move forward by pushing against the ground while bending and curling its body. Thus, option C is correct.
What level of organization are present in snake?The body of a snake is long and slender, and it is separated into four quadrants. Head, esophagus, heart, and trachea make up the first quadrant's major structures.
The second quadrant contains the liver, stomach, and anterior, vascularized region of the lung(s).
A snake has a basic skeleton because it has no arms or legs. Hundreds of ribs extend from the base of the tail to the end of the long, flexible spine that connects the head to the backbone.
This enables the snake to move forward by pushing against the ground while bending and curling its body.
Therefore, tissue system level of organization is represented by the skeleton of the snake.
