Which bases are found in a strand of dna? thymiwhich bases are found in a strand of dna?

Biology
2 answers:
NISA [10]3 years ago
8 0

Answer:

The correct answer will be adenine, guanine, cytosine and thymine.

Explanation:

Strand of DNA is made up of nucleotide monomers. Each nucleotide is made up of a 5C sugar (deoxyribose), a phosphate group and four nitrogenous bases (adenine, guanine, cytosine and thymine).

Sugar and phosphate form the backbone of the DNA molecule while nitrogenous bases are attached perpendicular to the backbone bonded to a complementary base on another strand by a hydrogen bond.

Thus, adenine, guanine, cytosine and thymine is the correct answer.

A swimmer sprints a short distance for a competition. The swimmer is not able to take in enough oxygen to make the ATP needed fo
Reptile [31]

When the swimmer is unable to take in enough oxygen for the sprint, the ATP (Adenosine triphosphate) will be compromised. In such conditions, the body will use anaerobic respiration to produce the ATP. Anaerobic respiration takes place in the absence of oxygen. It used the electron acceptors in place of the oxygen in the respiratory cycle. The amount of the ATP produced is, however, less in anaerobic respiration.

Hence, the answer is 'Option C - Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen'.

A bacterial sample has a cell density of 1.85 x106 CFU/mL. What plate dilution should yield a countable plate? Which two dilutio
insens350 [35]

Answer:

Explanation:

Bacterial count in stock- 1.85x10^6 cfu/ml

Dilution methods

Take 100 uL or (0.1ml) from stock and add to 900ul (0.9ml) saline and mixed it- this makes 10^1dilution.

Now take 100ul from 10^1 dilution and add to next 900ul saline this is 10^2 dilution, similarly do upto 10^5 dilution.

Then take 100ul from 10^ 4 and 10^5 dilution seperately and plate on LB agar plate seperetely and count the colonies.

Cfu/ml formula= (No.of colonies x dilution factor)/0.1 ml

So suppose, 18 colonies formed on 10^4 dilution then total no. Of cells in stock will be 18x10^4/ 0.1= 18x10^5 cfu/ml.

If we dilute 10^4 or 10^5 that's leads to colony count of 18-19 colonies on 10^4 dilution while 2 colonies should come on plate of 10^5 dilution.

Natural selection involves energetic trade-offs between ________. Group of answer choices high survival rates of offspring and t
koban [17]

Answer:

The correct answer is ''high survival rates of offspring and the cost of parental care''

Explanation:

Natural selection is the differential reproduction of some genetic variants with respect to others. Natural selection favors individuals who maximize their total reproductive success throughout life, that is, it favors certain phenotypes or variants are associated with greater offspring and / or greater survival, that also means that selection will favor those who stop spending on a particular breed at the right time to invest in another, that is, the amount of energy invested in each of them. This same natural selection also favors those genes that make it effective when the body that carries them is in development to extract all possible parental investment from their parents.
