Which of the following is not one of the four major groups of biomolecules found in living organisms? O carbohydrates O lipids O Phosphoric Acid O proteins
Answer:
Phosphoric Acid is not one of the major 4.
Explanation:
Phosphoric acid is not one of the four major groups of biomolecules found in living organisms. Thus, the correct option for this question is C.
What are Biomolecules?Biomolecules may be defined as those organic molecules which are significantly required in order for the survival of living organisms. This is because these molecules play essential functions like cell division, gradual development, morphogenesis, etc.
The four groups of biomolecules which are found in living organisms are Carbohydrates, lipids, proteins, and nucleic acids. Among which carbohydrates are energy-deriving biomolecules, proteins govern the structural and functional properties of the living cell.
Nucleic acids are responsible for the representation of genetic material and lipids are known for energy storage due to their large simple structure.
Therefore, phosphoric acid is not one of the four major groups of biomolecules found in living organisms. Thus, the correct option for this question is C.

How is the atomic mass of an atom calculated?
Answer:
Protons + Neutrons = Atomic Mass
Explanation:
Each Proton and Neutron weigh one (amu) adding all the protons and neutrons together gives you the atomic mass. (Electrons count as the .0 and don't play much part. Just round to the nearest number.)

When a cell does not contain a nucleus, where is the DNA?
Answer:
The cytoplasm
Explanation:
Prokaryotic cells do not have nucleui so their DNA floats around in the cytoplasm.
Answer:
The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. Many prokaryotes also carry small, circular DNA molecules called plasmids, which are distinct from the chromosomal DNA and can provide genetic advantages in specific environments.
Explanation:
Suppose a bacterial infection kills off most of the prey at point B on the graph. How would this affect the predator and prey growth curves on this computer model at point C? At point D?
If an infection kills most of the prey at a point ( B ) before the predators can get to the preys at point ( c ). The number of predators between points B and C will reduce due to the unavailability of prey to feed on.
Therefore at points C and D the amount of available predator will decrease while the number of available prey will gradually increase because of the scarcity of predators which would have negatively contributed to their growth just like the bacterial infection.
Hence we can conclude that The predator growth curve at point C and D will be ; Negative ( decreases ) while The prey growth curve at point C and D will be ; Positive ( Increases ).

^^ which of the following would have the highest species richness?
The correct answer as to which has the highest species richness would be an ecosystem with 30 species with varying numbers of each population.
The species richness of an ecosystem literally refers to the number of unique species in that ecosystem irrespective of the population size of each of the species. For example, an ecosystem with 20 species each with a population size of 50 is richer in species than an ecosystem with 10 species each with a population size of 200. This is why the species richness of an ecosystem is one of the attributes used in measuring the diversity of that ecosystem.
Hence, an ecosystem with 30 species is richer than those with 25, 15, and 5 irrespective of the population size of each species.

why don’t the two girls look the same using those word choices ?
Answer:
The process of meiosis involves cell division in which results in 4 daughter cells. Each cell has half the number of chromosomes of the parent cell. Genes are what determine what each cell obtains. A unit of genes is transferred from a parent to offspring. In some cases they are spreaded equally among the eggs therefore creating identical twins. While in other cases they are not distributed in variation, creating fraternal twins.
The two girls in the images do not look identical due to there being two separate eggs that were fertilized by the sperm. Independent assortment causes genes to separate from each other when reproductive cells develop. Variation defines the difference between the DNA in two individuals. Crossing over happens when the exchange of genes between homologous chromosomes results in parental mixture to the offspring. When this occurs, the genes are uniquely developed between the two eggs.
As you can see, the methodology for the making of two non-identical twins posses a series of steps. A variation of features is created due to genes determined by independent assortment. Meiosis is what divides the cells into daughter cells for fertilization by the sperm. All of which was talked about holds a great purpose in the process.

Please answer my question.
*Silly, Incomplete and/or Spam answers will be reported!*
Answer:
A
Explanation:
Vegetative reproduction is a type of asexual reproduction that results in new plant ... Plants have evolved different reproductive strategies for the continuation of their species. ... The flower is the reproductive organ of plants classified as angiosperms. External plant structures such as leaves, stems, roots, flowers, fruits, and seeds are known as plant organs. Vegetative parts include roots, stems, shoot buds, and leaves; they are not directly involved in sexual reproduction. So yes, flowers can be characterized as part of vegetative in means of reproduction of flowers
