On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. 2. The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. A bacteriophage, or bacteria virus, injects its DNA into the bacteria. ... The DNA is then replicated when the bacteria undergo cell division. 3. A lysogenic virus can remain inactive for a period of time. In lysogenic infection, viral DNA gets integrated with the host cell's DNA, where it is copied along with the host cell's DNA when the host cell replicates. ... It then removes itself from the host cell's DNA and enters the lytic cycle. The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse). 4. So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms. brainliest?
Explanation:
The four levels of protein structure are primary, secondary, tertiary, and quaternary structure. Review the levels of protein structure by clicking the image below.
Drag each label into the appropriate bin depending on whether it applies to primary, secondary, tertiary, or quaternary structure.
Proteins are composed of a sequence of amino acids linearly arranged. To accomplish their functions thet must adopt different structures. Primary structure: Amino acid sequence. Secondary structure: Alpha helix. Beta pleated sheet. Results from hydrogen bonding between the backbone constitutents of the polypeptide. Tertiary structure: Results from interaction between side chains (R groups) of amino acids. The overall shape of the polypeptide. Quaternary structure: The aggregation of multiple polypeptide subunits.
What is the protein structure?Proteins are molecules composed of several amino acids.
Amino acids are monomers composed of
a central carbon, a hydrogen atom, a carboxyl group (COOH), an amine group (NH₂), and an R group.
The R group is what differentiates one amino acid from another one.
Several amino acids linearly arranged and connected by peptidic bonds compose the polypeptide.
The peptidic bond is the union of two amino acids by their carboxyl and amine groups.
The R group of each amino acid stabilizes the molecule through their interactions.
The amount of amino acids that compose the polypeptide and their order in the chain determines the primary structure of the protein. The primary structure of the proteins determines the tertiary one.
Protein functions also depend on the amino acid sequences. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.
The primary structure is basically, the sequence of amino acids in the chain. It refers to the amino acid arrangement.
The secondary structure is achieved through hydrogen bonds (between -CO- and -NH- groups), when the polypeptidic chain folds and different regions of the molecule get in touch. The molecule can adopt conformations like the alpha-helix and beta-sheet.
The three-dimensional structure involves a higher folding degree, in a tridimensional space. This level makes the protein even more stable in the environment and capable of accomplishing its functions.
The quaternary structure can be seen when proteins are composed of more than one subunit. The way in which these subunits arrange is the fourth structure.
The hydrophilic R-groups stay permanently in the molecule interior, avoiding interaction with water.

Explanation:
You have a stock solution of ampicillin which has a concentration of 150 mg/mL and you would like to make 250 mL of LB-Amp media with a final concentration of 15 micrograms/mL ampicillin. What volume of the stock solution do you need to add? Show all of your work:
To determine the volume of stock solution needed, divide the number of moles of glucose by the molarity of the stock solution 37 g.
100 mL, or 0.1 L, of the stock solution is all that is required. Use the dilution equation M1V1 = M2V2, where M is the solution's concentration in mol/L, V is the volume in litres, and 1 and 2 are the concentrated and diluted conditions, respectively. The following equation uses the millilitre as the base unit of volume (v) to generate a percent v/v solution: mL of solute/100 mL of solution equals % v/v. An illustration is X% = 5.0 mL HCl/100 mL of solution. X/100 = 5.0/100. 100X = 500. X = 5.0%% v/v. Exchanges, news websites, and third-party websites with stock market data are all options.

Where is DNA found in the strawberry plant? (Hint, as this is a EUKARYOTIC PLANT, so there are a total of THREE organelles that contain this nucleic acid).
Answer:
Nucleus
Explanation:
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.
In a eukaryotic plant such as a strawberry, DNA can be found in three organelles: the nucleus, mitochondria, and chloroplasts.
Eukaryotes are organisms that have cells with a nucleus and other membrane-bound organelles. These cells are more complex than the cells of prokaryotes, which do not have a nucleus or membrane-bound organelles. Eukaryotes include organisms such as animals, plants, fungi, and protists. The presence of a nucleus allows for the separation of genetic material from the rest of the cell, which enables greater control over gene expression and regulation.
Additionally, the various organelles within eukaryotic cells provide for more specialized functions, such as energy production, protein synthesis, and waste disposal. Eukaryotes also have a cytoskeleton, which helps maintain cell shape and enables movement. The evolution of eukaryotic cells is believed to have arisen through a process called endosymbiosis, in which prokaryotic cells engulfed other cells that eventually became organelles.

n this project, you will analyze claims about the causes of inherited genetic variation. You will then make your own claim based on prior knowledge. Next, you will defend your claim by conducting research to gather information that supports it. Finally, you will present your claim and defense in a typewritten paper.
Answer:
See below
Explanation:
There are several reasons that genetic variation occurs. Some of them are as follows: mutation, random fertilization, recombination event during meiosis etc. The way in which this variation in genetics is distributed is in a continuous way. In case of the human species, it is reported that 85% of all variation is within a certain population, while the remaining 15% of genetic variation is between populations.
Answer:
The two major causes of the inherited genetic variation are 1-mutations during DNA replication and 2-crossing over during meiosis
Explanation:
The mutations are changes in the genetic information that may be inherited when they occur in germline cells (i.e. sperms and ova). Mutations include single nucleotide polymorphisms (SNPs), insertions and deletions (collectively named indels), and major chromosome arrangements such as, for example, aneuploidy, centric fusion, duplications, etc. On the other hand, the crossing over or recombination is the exchange of genetic material between non-sister chromatids of homologous chromosomes during Prophase I of Meiosis. Recombination is a phenomenon that generates new genetic combinations in the gametes and thus increase genetic diversity. Both germline mutations and crossing over events increase genetic variation in the offspring of the next generation, thereby these phenomena represent sources of inherited variation.

Steps of Double Fertilization.
It was discovered by S.G. Nawaschin (1897) Lilium are Fertillaria sps.1. Germination of pollen on stigma :
(i) By absorbing secretion of stigma pollen swells up and outer layer exine ruptures whereas inner lintine comes out in the form of pollen tube.
(ii) Branched polen tube is formed in amentiferae group.
(iii) In families malvaceae, cucurbitaceae, etc. polysiphonous condition (many pollen tubes from a single pollen) is found.
2. Path taken up by pollen tube :
(i) Pollen tube pierces through stigmatic papilla into the tissue of style.
(ii) Filiform apparatus of synergids secrete some chemotropically active substances, which promotes porogamy.
(iii) Obturator (special structure) act as a bridge for growth of pollen tube.
(iv) Cations are naturally occurring chemotropic agents in the pistil.
3. Entry of pollen tube into embryo sac :
(i) It enters into the ovule by either of the two methods; porogamy, chalazogamy or mesogamy.
(ii) Irrespective of the mode of entry of pollen tube into the ovule, the pollen tube always enters into embryo sac at micropylar end (Porogany).
(iii) If enters through chalaza (base) it is termed chalazogany.
(iv) If pierces through integuments, it is called mesogamy.
(v) Tip of pollen tube penetrates embryo sac and reaches egg apparatus.
4. Syngamy (Generative fertilization)
(i) Pollen tube burst as tube nucleus disorganises.
(ii) One of male gametes fuses with egg cell or oosphere.
(iii) Deploid oospore or zygote is formed.
5. Triple fusion (Vegetative fertilization) :
The other gamete fuses with secondary nucleus forming triploid primary endosperm (PEN) which later give rise to endosperm.
Answer:
Double fertilization is a process unique to flowering plants (angiosperms) in which two sperm cells fertilize two different structures within the female reproductive system. The steps of double fertilization are:
Pollination: transfer of pollen grains from the male to the female flowerGermination: the pollen grain forms a pollen tube and grows down the style towards the ovuleSyngamy: the first sperm cell fuses with the egg cell to form a diploid zygote (2n)Endosperm formation: the second sperm cell fuses with two polar nuclei to form a triploid cell (3n) which undergoes cell division to form the endospermEmbryo formation: the zygote undergoes several rounds of cell division and differentiation to form the embryoDouble fertilization leads to the formation of both the embryo and endosperm within the ovule, which ultimately results in the development of a seed.
