3. Which process is most directly involved in the
production of egg cells by a female frog?

Answer:

A chain of reactions is initiated upon soil flooding leading to reduced (low) soil redox potential (Eh, mV) conditions. These reactions include physical, chemical and biological processes that have significant implications for wetland plants.

Explanation:

Bacterial cells are very small - about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). ... One reason why bacterial cells are so small is that they need a large surface area to cell volume to take in nutrients.

Answer:

the nitrogen cycle, the water cycle, and the carbon cycle

Explanation:

The water, carbon, and nitrogen cycles move nutrients through the different parts of an ecosystem. Water moves through organisms and the environment in different phases. Carbon moves through an ecosystem in carbon dioxide, minerals, and organic compounds. Nitrogen moves through an ecosystem in nitrogen gas, ammonium, nitrates, and organic compounds.

The biogeochemical cycle is a pathway that circulates the chemicals through the abiotic and the biotic factor. The nitrogen, water, and carbon cycle through various regions of an ecosystem.

The biogeochemical cycle is the movement of the chemicals and compounds of carbon, nitrogen, and water in the biosphere (biotic) and the atmosphere, lithosphere, and hydrosphere (abiotic) spheres of the earth.

These cycles move the nutrient through different spheres in the form of inorganic and organic compounds. It is an essential part of the ecosystem as they regulate the flow of the natural elements.

Therefore, option 1. nitrogen cycle, option 2. water cycle, and option 3. carbon cycle move through various parts of an ecosystem.

Answer:

Condensation

Explanation:

Condensation is the phase change from gas to liquid. For example, water vapor condenses when you are taking a shower because wet spots show up on a mirror after taking a shower.

Answer:

Condensation

Explanation:

Sublimation is when a solid turns into a gas. Condensation is when water in the air collects to form droplets that gather on a surface/object. Vaporization is when a liquid forms into a gas. Transpiration is a thing in plants where water transfers throughout the plant.

Explanation: Abiotic factors for fish is water, temperature, amount of dissolved oxygen in water, etc. Penetration of sunlight is also important in fresh water habitat. Biotic factors are predators, disease causing organisms, organisms available as food, population density of competitors, etc.

Answer:

1. Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

2. Summary: Changes in the size and form of the beak have enabled different species to utilize different food resources such as insects, seeds, nectar from cactus flowers as well as blood from iguanas, all driven by Darwinian selection

3.  Medium ground finches with larger beaks could take advantage of alternate food

4. three species of Darwin's tree finches have been known to inhabit Floreana  but no birds singing that song on Floreana have been heard in many years.

Explanation:

the northern hemisphere is the opposite from the southern hemisphere

Since northern and southern hemisphere are in opposite directions therefore, option (A) is correct.

The axis of rotation of the Earth is inclined with regard to the plane in which it orbits the sun. This is the root reason of the changing of the seasons. When the axis of the earth is aligned with the sun, summer arrives in that hemisphere of the planet. Expect winter to arrive when the axis of the earth is tilted away from the sun.

Different places of Earth receive the Sun's most direct rays throughout the year. When the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, the Northern Hemisphere experiences winter.

Answer:

recombinant DNA

Explanation:

In molecular biology, recombinant DNA molecules are genetic sequences formed by combining DNA material from different sources (i.e., organisms, populations, species, etc). Proteins produced from DNA recombinant molecules are known as recombinant proteins. Molecular cloning is the most widely used technique in molecular biology in order to produce recombinant DNA molecules. In this technique, a cloning vector such as, for example, a plasmid of a bacterium, is used to insert a foreign DNA fragment into another cell which is then expressed in the host cell.

The test that will be most useful to determine the identity of the single-celled organism is to "determine if it has a nucleus".

DIFFERENCE BETWEEN A PROTIST AND MONERAN:

A protist is a member of the kingdom protista characterized by it's single cells and eukaryotic nature.

On the other hand, a MONERAN is a member of the kingdom MONERA and characterized by it's unicellular and prokaryotic nature.

The major difference between Monera and protista is their prokaryotic and eukaryotic cells respectively. Prokaryotic cells do not have a membrane bound nucleus while an eukaryotic cell does.

Since the major difference between Monerans and protists is their possession of a membrane bound nucleus, the identity of the single-celled organism is to "determine if it has a nucleus".

Answer:

Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.

Explanation:

DNA

They can look at the DNA it's the most common one.

There are 4 pieces of evolution and they are

Fossils , Geography , Embryos / DNA , Anatomy

Fossils: Physical remains of species , Determine age, location,  environment

Deeper layers = older

Geography: Proves species share common  ancestors, depending on where

they live

DNA: BEST evidence because it’s the  MOST ACCURATE

Similarities in the early stages of  development

Similarities in DNA

More similarities = closely related

More differences = not related

Anatomy: Compare body parts of different  species to see how they evolved

3 different structures:

Homologous (same structure,  different function)

Analogous (similar structure,  different organisms)

Vestigial (body parts that no  longer serve a purpose)

All of that are in evolution
