Answer:
The solubilities in water of the three molecules from most to least soluble is in the following order: phosphate > deoxyribose > guanine.
Explanation:
The phosphate group is the most water-soluble due to it being very much negatively charged .
The deoxyribose which has several hydroxyl groups, is the next most water-soluble molecule.
The guanine molecule is hydrophobic, therefore, it is the least soluble in water.
A DNA molecule is composed of the three molecules: deoxyribose sugar, a phosphate group and a nitrogenous base which could either be a purine or a pyrimidine.
The three dimensional structure of DNA is such that the the phosphate groups and deodyribose sugars form the backbone of the structure on the outside of the DNA double helix where they are exposed to the aqueous environment of the nucleus. On the other hand, the hydrophobic nitrogeneous bases are located in the interior of the double helix where they are excluded from excludedthe aqueous environment of the nuclues. This structural arrangement is in accordance with the solubility of the molecules where the water-soluble phosphates and sugars are exposed to water while the water-insoluble bases are away from water.

What happens when a continental plate and a oceanic plate converge and why? Choose one.
(no links please)
a. The continental plate goes under the oceanic plate (subducts) because the continental plate is
thinner than the oceanic plate.
b. The continental plate subducts under the oceanic plate because the continental plate is thinner
than the oceanic plate.
c. The oceanic plate subducts under the continental plate because the oceanic plate is lighter than the continental plate.
d. None of these
e. The oceanic plate subducts under the continental plate because though the oceanic plate is
thinner than the continental plate, it is more dense.
pleaseee helpppp

Answers
Answer: i think it's e
Explanation: When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser.

how do autotrophs breakdown energy that it created through photosynthesis
Answers
Answer:
Some types of bacteria are autotrophs. Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar.

Which of the following types of power does not use a turbine to generate
electricity?
O A. Wind
B. Nuclear
C. Coal
O D. Solar
Answers
D. Solar
Explanation:
Solar converts sunlight directly into electricity without the need of a turbine
Solar does not use a turbine to generate electricity. Therefore, option (D) is correct.
What is Solar power?
Solar power is a renewable and sustainable energy source that generates electricity by harnessing the energy from the sun. It is a clean energy alternative to fossil fuels, as it does not produce harmful emissions or pollutants that contribute to climate change.
Solar power systems use photovoltaic (PV) cells, which convert sunlight into direct current (DC) electricity. An inverter then converts the DC electricity into alternating current (AC) electricity that can be used in homes and businesses.
Solar power is becoming more affordable and accessible, and many governments around the world offer incentives to encourage the installation of solar panels. The growth of solar power has the potential to reduce greenhouse gas emissions, create jobs, and provide energy access to remote communities.

Answers
Answer:
A
Explanation:
the process involves replication of cell's chromosomes, segregation of the copied DNA and splitting of parent cell's cytoplasm
In order for genetic material to be passed to cells during cell division, DNA replication should take place, as in Option A, and the passing of genetic contents varies between mitosis and meiosis.
What is the significance of DNA replication in cells?DNA replication is the process by which the genetic contents of a cell, the DNA, are copied which is a crucial process that occurs in all living organisms and is necessary for the maintenance of their genetic information and the transmission of this information to the next generation, it is essential for cell division and growth, as well as for the repair of damaged DNA and plays a central role in animals and plants, as new life can form and cell division takes place due to this process.
