Answer:
Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular, A always pairs with T, and C always pairs with G. Then, during DNA replication, the two strands in the double helix separate.
Explanation:
The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.

A) The new root growth is a result of meiosis
B) the new plant formed from as reproduction
D) The new plant is genetically identical to the original plant.
The new plant grows vegetatively from the cutting and will look exactly like the original plant.
Vegetative propagationCutting is a form of vegetative propagation attribute of some organisms.
Cutting a tissue off a plant and the tissue developing its own root to become a new plant happens by mitosis.
Mitotic division of the cut tissues leads to the formation of roots and the eventual growth to a new plant.
Mitotic growth means that the new plant will be genetically and physically identical to the parent plant, provided they grow under the same conditions.

Which equation shows how matter is transformed and conserved in photosynthesis? In other words, which is the balanced chemical equation for
photosynthesis?
O 602 + 6H2O + Sunlight → CH208 + 6CO2
O 6CO2 + 6H2O + Sunlight → CH,20g + 602
O CH120o + 6CO2 → 602 + 6H20 + Sunlight
son
CH,208 + 602 → 6CO2 + 6H2O + ATP
Answers
Answer:
B
Explanation:
The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2
the answer is not exact, but it is the closest to the actual equation
The equation shows how matter is transformed and conserved in photosynthesis is O 6CO2 + 6H2O + Sunlight → CH,20g + 602. Thus, option B is correct.
What is photosynthesis?Photosynthesis can be described as a process which plants use to produce their own food. In this process, carbon dioxide and water get converted into sugar (glucose) and oxygen. Light energy from the sun is needed for this reaction to occur. The excess oxygen produced by this process is released into the atmosphere. The sugar made is used as fuel by the plant.
Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules. Cellular respiration can occur in the presence of oxygen (aerobic) and this combines glucose molecule to form carbon dioxide (CO2) and water (H2O) and release energy for use.
The equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy (ATP). The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2.
Thus, option B is the correct option.

If you found a white sheep and wanted to determine its genotype, with what kind of animal would you cross it
Answers
The ideal would be to cross this sheep with several black sheep and observe the color of each offspring.
We can arrive at this answer because:
When crossing white sheep with black sheep it is possible to observe the genotypes of the offspring to determine the genotype of the white sheep.This will be even more efficient if we know the genotype of the black sheep.In this case, if the crossing of the white sheep with the black sheep generates an offspring with all individuals with black fur, we can determine that the white sheep has the h0m0zygous recessive genotype.If the offspring is composed entirely of individuals with white fur, we can state that the white sheep has the dominant h0m0zygous genotype.If the offspring have most of their members with white fur and a small amount with black fur, it means that the white sheep has a heterozygous genotype.In this case, the observation of the offspring's fur is essential to determine the genotype of the white sheep.

There are 100 ants in an ant farm that is 10 inches by 5 inches. What is the population 1 density? (Show your work)
Answers
The population density would be 2 ants/square inch
Population density is defined as the population size of a species of organism per unit area of the habitat occupied.
In this case, the population size of ants in the ant farm is 100 while the dimension of the ant farm is 10 inches by 5 inches.
Area of the ant farm = Length x breadth
= 10 x 5
= 50 square inch
Population density of ant = population size/area
= 100/50
= 2 ants/square inch

The gonads and adrenal glands typically generate the natural steroid hormones from cholesterol. Lipids are the hormones in these forms. Thus, option A is correct.
What is the role of lipid in the body?Lipids serve as the body's energy reserve, control hormones, carry nerve signals, protect key organs, and transport nutrients that are fat-soluble.
Food fat gives texture and flavor, has a high caloric density as an energy source, and helps people feel full.
The body naturally creates hormone-like chemicals, but steroids are synthetic copies of such substances.
They go by the name corticosteroids and are distinct from the anabolic steroids used by athletes and bodybuilders.
