Which of the following would eat a hamburger with lettuce on it?
A) carnivore
B) detritivore
C) herbivore
D) omnivore
An Omnivore would eat a hamburger (animal) with lettce (plant) on it. Therefore option (D) is correct.
What do you mean by Omnivore ?
An animal classified as an omnivore consumes both vegetation and other animals. Some omnivores, such as carnivores that consume herbivores and other omnivores, will hunt and consume their meal. Some individuals are scavengers and will consume dead things. Many people eat eggs that belong to other species.
Not all types of plants are consumed by omnivores. Omnivores, unlike herbivores, are unable to digest some components of grains or other non-fruit-producing plants. However, they are able to eat fruits and vegetables. In this simulation, some of the insect omnivores are pollinators, which are crucial to the life cycle of several plant species.
Therefore, omnivore is the correct option (D) among other options.

g Knowing if a bacterium is Gram-positive or Gram-negative is important in medicine because it tells us what type of antibiotic will be used (e.g., penicillin for Gram-positive bacteria and mycins, like streptomycin, for Gram-negative bacteria). Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a True b False
Answer:
This is true.
Explanation:
Knowing whether a bacteria is gram positive or negative will help to narrow down the types of pathogen it could be and will determine which antibiotics will be effective against it.
Knowing whether a bacteria is gram positive or gram negative will help to understand the kind of infection it may cause and thus help in determining the kind of antibiotic it needs.
What are gram-positive and gram-negative bacteria?The bacteria that have a thick layer of peptidoglycan but no outer lipid membrane are called Gram-positive bacteria. The bacteria that have a thin layer of peptidoglycan and an outer lipid membrane are called gram-negative bacteria.
Gram-positive bacteria do not have an outer lipid membrane and hence they retain the crystal violet in the thick peptidoglycan during gram staining and it is fixed by iodine.
The outer lipid membrane that is possessed by the Gram-negative bacteria does not allow them to retain the crystal violet and hence only the counterstain safranin is visible in the gram staining method.
The technique of Gram staining was developed by the bacteriologist Hans Christian Gram in 1884. While this method cannot tell the specific strain of a bacteria, it can be used as a quick and easy way for narrowing down the basic criteria of distinguishing the bacteria among the two main groups.
Therefore, knowing whether a bacteria is gram positive or gram negative will help to understand the kind of infection it may cause and thus help in determining the kind of antibiotic it needs.

Is a pig crossed with a chimp possible, I just read an article about this and the person who had the idea was someone with the last name MCkarther PH.D. it made the news.
Answer:
The cross between two different species is called hybridization. The truth is that, for hybridization to occur, the species in question must have a certain kinship with each other, that is, they must belong to the same family of animals. An example is the cross between tigers and lions, pigs and wild boars, donkeys and donkeys, etc. Now, if there is no such familiarity between species, the truth is that hybridization will not be possible, which is the case of pigs and chimpanzees with each other.
All the following stages must occur for a woman to get pregnant. However, after which stage can a woman be described as pregnant?
Answer: The legislation repeatedly refers to that point as "20 weeks after fertilization." Medically, however, a pregnancy is generally "dated" from "gestation," defined as the time of the woman's last menstrual period, because that is a date most women can pinpoint.

example of
Energy ?
1.)Potential
2.)Kinetic
Answer: A roller coaster at the top of a hill JUST BEFORE it goes over the edge is an example of potential energy.
Explanation:
An energy that is acquired by an object due to its motion is called kinetic energy.
An energy that is acquired by an object due to its position is called potential energy.
For example, when a roller coaster at the top of a hill JUST BEFORE it goes over the edge has only potential energy because it is not in motion.
The energy present in the roller coaster is due to its position that is being at the top of a hill.
Thus, we can conclude that a roller coaster at the top of a hill JUST BEFORE it goes over the edge is an example of potential energy.
What happens during meiosis II?
O A. A total of four daughter cells form.
B. DNA double to produce sister chromatids.
C. Tetrads form at the center of a cell.
D. Two diploid cells are produced.
During meiosis II, the process of cell division that follows meiosis I, a total of four daughter cells form that are haploid in form and present in option A as the daughter cells are called as gametes here.
What is meiosis?Meiosis is a type of cell division that results in the production of haploid cells from a diploid cell, and during meiosis, two rounds of cell division occur, referred to as meiosis I and meiosis II, and in meiosis I, the homologous chromosomes pair up and exchange genetic material in a process called crossing over. In meiosis II, each haploid daughter cell produced in meiosis I divides again, and the sister chromatids, which are identical copies of the same chromosome, separate from each other.
Hence, during meiosis II, the process of cell division that follows meiosis I, a total of four daughter cells form that are haploid in form and present in option A.

how is sound recorded
Answer:
Sound is made up of waves in the form of vibrations in the air. Or you can use the signal to record the sound on magnetic tape. This works by a similar process of moving a magnet, but that magnet causes a magnetic tape to gain magnetization in patterns that represent the sound.
In a digital recording system, sound is stored and manipulated as a stream of discrete numbers, each number representing the air pressure at a particular time. The numbers are generated by a microphone connected to a circuit called an ANALOG TO DIGITAL CONVERTER, or ADC.

Explanation:
Answer:
sound is made up of waves in the form of vibrations in the air, and can be detected by the human ear. Using magnets analoque technology takes sound waves and turns them into electrical pulses. When a metal conductor is moved inside the magnetic field an electric current is produced in that wire.
