Which of the following is the best statement comparing the water of today with the water
that was here 100 million years ago? (1 point)
A) Water enters and leaves Earth duing evaporation and precipitation cycles.

B) The water present on Earth today is made of the same atoms but the molecules
have been recycled through biologic activity.

C)The atoms that made the water then were destroyed when they were used; the
atoms that make up water now were made more recently.

D)The molecules of water then are the same molecules that exist today.

Answers

Answer 1

Answer:

A. Water enters and leaves Earth during evaporation and precipitation cycles.

Explanation:

Answer 2

Answer:

B

Explanation:

C is wrong because, atoms cannot be destroyed or made according to the law of conservation of mass. D is wrong because water goes through many processes, like A states, but both are wrong because B is the most correct.

where do photosynthetic organisms get the energy needed to make sugars during the light-independent/dark reactions?

Answers

Answer:

They use the glucose they have stored from previous photosynthesis reactions.

Explanation:

The dark reaction takes place external to the thylakoids. The energy from ATP and NADPH is used in this process to fix carbon dioxide (CO2).

What is light-independent/dark reactions?

Carbon fixation, reduction, and regeneration are the three stages that make up the Calvin cycle, which is another term for the dark reactions that take place during photosynthesis.

The stroma of the chloroplast is the location where the light-independent process, also known as dark reactions or the Calvin-Benson cycle, is carried out. Carbon-based molecules are formed through a chain of chemical events that begin with carbon dioxide. The production of ATP and NADPH during the light-dependent process supplies these processes with the energy they need to proceed.

Elastic


Movement

Answers

Answer:

elastic

Explanation:

The kinetic energy of a body can be decreased in two cases: When it is stored in the form of potential, for example: elastic or gravitational energy. Or when there are dissipative forces capable of transforming it into other forms of energy, as does the friction force. Which transforms kinetic energy into thermal energy.

You are attempting to carry out a transposon mutagenesis experiment using the pRL27 system. The Donor strain you use was giving to you by a lab mate who has been culturing it continuously for several months. When you set up your control plates, you find that the Donor strain grows poorly on Luria DAP Agar. Your transformation efficiency is very poor for this attempt at mutageneis. What likely happened to the Donor strain

Answers

The most likely happened to the donor strain is that the transposon is active in the donor resulting in the gradual accumulation of mutations. The accumulation of mutations is promoted by the insertion of the transposon.

A donor strain is a bacterial strain that contains a mobilizable fragment of DNA called plasmid.

These strains (donor strains) exploit the transference properties of a conjugative plasmid to modify a particular recipient strain.

Transposons, also known as jumping genes, are mobile genetic elements that alter the genome of an organism by jumping and thus inserting them into genetic sequences (i.e., into protein-coding sequences).

In this case, the presence of a transposon in the donor strain affected the expression of many genes required for the donor strain in order to grow into Luria DAP Agar.

Cetaceans (whales, dolphins, and porpoises) are all Mammals. Whales usually are larger and slower in the water. Porpoises normally do not have a pronounced beak as a dolphin would. Dolphins have a curved dorsal fin. Dolphins and Porpoises are extremely intelligent. They are warm-blooded. All dolphins are whales, but not all whales are dolphins. Different animals live in different areas. Killer whales are adapted to colder areas, and they stay in the colder water. Bottlenose dolphins are best suited for warmer areas such as the Atlantic Ocean, so they will have less body fat or flubber because they live in a warmer climate. The Killer Whale will need more body fat because of the colder temperatures. They have smooth bodies to help them swim. They have tiny hairs, but as they age, the hair disappears. They can stay underwater longer based on their breathing and extract oxygen from water; they make super high pitch noises that Bounce off objects in the water Back towards the Dolphins to help determine the location; this is called Echolocation.

Explanation:

Before, the deer mice were easy prey for predators since their color stood out and the predators could find them. Therefore, the change of color allowed them to hide better from predators. You may be tempted to answer a, but if you read carefully it says "The change of color camouflaged them, which helped them HUNT better." Clearly A is wrong since deer mice don't really hunt.
