The stroma is the Group of answer choices space between the inner and outer membranes of a chloroplast. watery fluid enclosed by the inner membrane of a mitochondrion. thick fluid enclosed by the inner chloroplast membrane. space between the inner and outer membranes of a mitochondrion.
Answer: The correct option to the question is (thick fluid enclosed by the inner chloroplast membrane).
Explanation:
Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle. In electron micrographs, thylakoid membranes look like stacks of coins, although the compartments they form are connected like a maze of chambers. The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the STROMA
The STROMA is made up of thick colourless fluid which surrounds the thylakoid and is enclosed within the inner chloroplast membrane. The stroma is essential for photosynthesis because:
--> it contains the enzymes necessary for carbon fixation,
--> it also manages the chloroplast response to cellular stresses and signaling between various organelles.
--> It plays an important role in both the light-dependent and light-independent reactions of photosynthesis.

Once a standard curve has been prepared by plotting numbers of bacteria (CFU/mL) versus absorbance for one species of bacteria, this curve can be used for estimating bacterial numbers by measuring absorbance for any species of bacteria.
a. True
b. False
Answer:
b. False
Explanation:
The biomechanism of bacterial growth may be examined, by graphing cell growth (also known as absorbance) vs incubation time of the bacteria. A standard growth curve is the result of this process. The amount of turbidity in the broth culture is proportional to the number of microorganisms present.
A standard curve produced for a particular species can't be utilized to predict the number of bacterial counts for a different species due to the listed factors.
The rate of bacterial cell reproduction varies from a particular species to another.Varying species have different absorbance thresholds.When species become challenging to classify, what is the most accurate technology for their identification?

Answer:
u should have to short the question bcz its confusing....
Explanation:
Some mutations, or changes in the sequence of DNA, do not have any effect on the characteristics of the organism. Why is this?
The protein built from this mutated sequence is deactivated by the cell.
The cell recognizes mutations and ignores them when expressing the gene.
The mutated sequence still codes for the same amino acid.
The immune system repairs the mutated sequence during development.
Answer:
The mutated sequence still codes for the same amino acid.
Explanation:
Mutations that have no effect on an organism's characteristics have mutated sequences that still code for the same amino acid.
Because it codes for the same amino acid that it was intended to, the proteins made from it will remain the same.
This means that there will be no effect or change on the organism's characteristics, because the protein will be the exact same.
So, the correct answer is that The mutated sequence still codes for the same amino acid.
Answer:
The mutated sequence still codes for the same amino acid.
Explanation:
This type of mutation is called a silent mutation. Despite a nucleotide in the codon being changed, the original codon and the mutated codon still code for the same amino acid. This results in no observable effect on the characteristics of the organism.

In legumes, Rhizobium bacteria are more commonly observed in the roots. The Rhizobium provided usable nitrogen while the plant in return provides shelter and food to the bacteria. What is the type of relationship between these both?Single choice.
(1 Point)
(a) Symbiotic, as both benefit each other for food.
(b) Competition, as both compete for atmospheric nitrogen.
(c) Parasitic, as Rhizobium consumes food prepared by plants.
(d) Saprophytic, as Rhizobium decomposes the roots of the plant and feed on them.
Answer:
(a) Symbiotic, as both benefit each other for food
Explanation:
Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism.
Mutualism is a symbiotic relationship in which both species benefit. An example of mutualism involves goby fish and shrimp. The nearly blind shrimp and the fish spend most of their time together. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone. From their relationship, the shrimp gets a warning of approaching danger. The fish gets a safe retreat and a place to lay its eggs.
Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. One species typically uses the other for a purpose other than food. For example, mites attach themselves to larger flying insects to get a “free ride.” Hermit crabs use the shells of dead snails for homes.
Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed. Many species of animals are parasites, at least during some stage of their life. Most species are also hosts to one or more parasites.
So. we can easily say that the relationship between them is symbiotic.

Nitrogen is an essential nutrient for plant growth. But farmers who cultivate pulse crops like Green gram, Bengal gram, Black gram etc., do not apply Nitrogenous Fertilizers during cultivation. Why?
Answer:
Nitrogen is so vital because it is a major component of chlorophyll.Nitrogen is the fuel that makes plants go. It's used to synthesize amino acids, proteins, chlorophyll, nucleic acids, and enzymes. Plants need more nitrogen than any other element.Farmers who cultivate pulse crops like green gram, Bengal gram, black gram, etc. do not apply nitrogenous fertilizers during cultivation because these crops have "rhizobium bacteria".
These plants are leguminous plants and they have symbiotic relationship with Rhizobium bacteria. This bacteria converts atmosphere nitrogen in a form that the plant can use, in return the plant provide them shelter and food. That's why they don't need extra nitrogen from fertilizers.
(a) Describe why DNA replication is said to be a semiconservative process. Explain how random mutations such as those in pathogens with a mutator phenotype may arise in the DNA of an organism.
Answer:
DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the original parental helical strands.
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. ... Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation.
Btw :
stay safe! :3
(a) In order to understand why the replication of DNA is said to be semi conservative, there is a need to understand what really goes on during replication.
During replication, the two strands of the DNA first become separated.Each strand then makes a complementary copy of itself.The original double strand does not reform, instead, the old strands each forms a double strand by coupling with their newly synthesized complimentary strands.The fact that the 2 double strands DNA that forms at the end of the replication process each consist of one old and one newly synthesized strand is why replication is said to be semi conservative. The old strands remain conserved but are now separated into new double strands.
(b) Random mutations such as those in pathogens with a mutator phenotype may arise in the DNA of an organism due to a host of factors:
mistakes during replicationmutation due to external factors such as chemicals, UV radiation, etc.When this happens, the DNA sequence is altered and this alteration creates one or more phenotypic effects.

When determining CFU/mL, plates with more than 300 colonies should be eliminated from analysis, being designated: Group of answer choices TNTC TSA TVAC TFTC
Answer:
TNTC
Explanation:
The correct option would be TNTC.
TNTC simply means Too Numerous To Count. The term is usually reserved for bacterial culture plates with high bacterial loads, usually in the excess of 300 colonies. It is as opposed to TFTC (Too Few To Count) which is the term used when the colony count on a bacterial culture plate is less than 30.
When a bacterial culture plate is too numerous to count, it can either be eliminated from data analysis or the sample diluted to lower the bacterial load.

In a particular population, the allele frequency of the ABO blood type alleles are as follows: IA is 20%, IB is 30% and i is 50%. If mating is random and the population is in Hardy-Weinberg equilibrium, what percentage of the population will have type O blood type
Answer:
The genotypic frequency F(ii) = 0.25 = 25%
Explanation:
Due to technical problems, you will find the complete explanation in the attached files
In the blood type cases involving the ABO group, the type of inheritance here is the co-dominance type of inheritance
The percentage of the population with type O blood will be 25%
Type A (IA) is dominant to type O (i) and at the same time type B (IB) is also dominant to type O (i).Using the equation - p² + 2pq + q² + 2pr + r² + 2qr = 1Where p² indicates the genotypic frequency with type A (AA) blood and q² indicates genotypic frequency of BB and r² indicates the genotypic frequency of OO.Since we are finding the percentage with type O blood (r²) where r (allelic frequency of type O) is 0.5 (50%)
r² = 0.5² = 0.25 = 25%.
