What is mid-ocean ridges?

The central parts of the oceans have mid-ocean ridges. The mid-ocean ridges are volcanic underwater mountain ranges.

There is constant propelling of magma, and as the magma cools off quickly it creates new crust.

This results in the mid-ocean ridges gaining heights of up to 1.5 km above the surrounding area.

Draw the structures of deoxyribose, guanine, and phosphate and rate their relative solubilities in water (most soluble to least soluble). How are these solubilities consistent with the three-dimensional structure of double-stranded DNA?

Answers

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.

Natural selection will only lead to evolution if it allows for an organism to ________.
a. possess advantageous traits.
b. compete for resources.
c. produce offspring.
d. all of the above.

Answers

Answer:

b

Explanation:

Natural selection will  only lead to evolution if it allows for an organism to process traits, compete for resources and produce offspring. The correct option is d.

What is natural selection?

Natural selection is indeed an evolutionary mechanism. Lifeforms which are better adapted to their surroundings are much more likely to flourish and pass on the genetic traits that helped them thrive. Species change and diverge as a result of this process.

Natural selection, Darwin proposed, is a framework for evolution in which genetic variants that help support life, reproduce and survive as well as become more prevalent in a population over time.

Natural selection will occur if three conditions are met, according to Darwin's theory. These conditions, which are outlined as,

Represent a struggle for survival.Exhibit variation.Undergo inheritance.

These are the conditions that are said to be both necessary and sufficient for natural selection.

Natural selection will only result in evolution if an organism is able to process traits, compete for resources, and produce offspring.

Thus, the correct option is d.

calculate the kinetic energy of a dodgeball that has a mass of 2 kg and velocity of 4 m/s after being thrown

Answers

Answer:

Kinetic energy of dodgeball = 16 kg-m/s

Explanation:

Given:

Mass of dodgeball = 2 kg

Velocity of dodgeball = 4 m/s

Find:

Kinetic energy of dodgeball

Computation:

Kinetic energy = (1/2)(m)(v²)

Kinetic energy of dodgeball = (1/2)(Mass of dodgeball)(Velocity of dodgeball²)

Kinetic energy of dodgeball = (1/2)(2)(4²)

Kinetic energy of dodgeball = (1/2)(2)(16)

Kinetic energy of dodgeball = (32/2)

Kinetic energy of dodgeball = 16 kg-m/s

Plants and seaweed provide most of the oxygen

Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.

What are seaweeds?

Some seaweeds are microscopic, such as the phytoplankton that live suspended in the water column and provide the base for most marine food chains. Some are enormous, like the giant kelp that grow in abundant “forests” and tower like underwater redwoods from their roots at the bottom of the sea.

Most are medium-sized, come in colors of red, green, brown, and black, and randomly wash up on beaches and shorelines just about everywhere.

The vernacular “seaweed” is a bona-fide misnomer, because a weed is a plant that spreads so profusely it can harm the habitat where it takes hold.

Therefore, Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.

Answers

Answer:

Certain plants contain compounds similar to ecdysone which serve as a defense against insects. False

Juvenile hormone levels are high in insect larvae, but must decrease in order for metamorphosis to occur. True.

Chemicals similar to ecdysone and juvenile hormone are widely used commercially to control insect pests. True

Explanation:

The plants produce toxic chemicals such as terpenoids, alkaloids, anthocyanins, phenols, and quinones as a defense against insects. Juvenile hormone levels are high in insect larvae but its concentration decrease when the insect transform into adult stage and in order to  occur metamorphosis. Ecdysone and juvenile hormone are widely used as insecticide because it prevents the insects to transform from larva to adult so if they can't mature they can't harm the plants or other things of our environment.

What is the main result of glycolysis?

Glycolysis, the initial step in cellular respiration involves the breakdown of glucose. One of the key outcomes of glycolysis is the splitting of a glucose molecule into two molecules of glyceraldehyde-3-phosphate (G3P).

This process occurs in the cytoplasm and does not require oxygen. Glycolysis serves as the primary source of energy production in anaerobic conditions and plays a crucial role in both aerobic and anaerobic cellular respiration.
