Which of these animals is considered a model for punctuated equilibrium?

Answers

Answer 1
Answer:

Ammonites

Ammonites are squid like creatures that are named after theEgyptian god, Ammon. This extinct creature is an example of the punctuatedequilibrium. Ammonites are the ancestors of the cephalopods. These creaturesalso came from the bactries. In the punctuated equilibrium, the ammonites haveshown that they were able to evolve thru cladogenesis.

Photosynthetic algae create sugars that will eventually be broken down during which process? A. glycolysis, during respiration B. the Calvin cycle, during photosynthesis C. electron transport chain, during respiration D. the Krebs cycle, during photosynthesis

Answers

The correct answer is:

glycolysis, during respiration

Photosynthetic algae create sugars that eventually be broken down during : A. Glycolysis, during respiration

During this process, Algae produced 2 ATP and 2 NADH, which is used in forming energy.

Explanation:

The cleavage down of sugars is called glycolysis. The prefix glyco- means sugar, and the suffix -lysis means breaking down. It's part of a three-step method in respiration, the other two is The Krebs Cycle and Electron Transport Phosphorylation. In the manner of glycolysis, 2 ATP and 2 NADH are designed. Glycolysis is the metabolic pathway that transforms glucose C₆H₁₂O₆, into pyruvate, CH₃COCOO− + H⁺. The free energy released in this manner is used to form the high-energy molecules ATP and NADH.

Which process enables the use of resources repeatedly​

Answers

Answer:

Reversible process

Explanation:

Reversible process is the process in which the reactants and the products both are used. They both are produced also. We can consume either the product or the reactant. So, if we need a resource to be produced repeatedly, we should put it in a reversible process.

The Siberian Husky is a medium dog, weighing between 16-27kg (35-60lbs). These dogs have strong pectoral and leg muscles, allowing them to move through dense snow. If they had heavier muscles, they would sink deeper into the snow and move slower. Yet, if they had lighter muscles, they would not be strong enough to pull sleds and equipment. This is an example of which type of natural selection? A)Directional selection



B)Stabilizing selection



C)Disruptive selection

Answers

The answer is B. Stabilizing selection. Stabilizing selection is a type of natural selection. Stabilizing selection is the opposite of disruptive selection where extreme values of a trait are favored over intermediate values. 

. Which of the following could be true of two different species that have a competitive relationship in the same ecosystem? a.) One species preys on the other.
b.) The relationship is mutually beneficial.
c.) They share the same niche.
d.) One species benefits, while the other is neither helped nor harmed.

Answers

Answer:

C (they share the same niche)

Explanation:

Competition is a relationship between organisms resulting in a contest when both are trying to use the same resources related to their growth, reproduction and survivability. It is as a result of limited resources. Competition occurs in virtually all ecosystems in nature. This relationship develops when more than one organism in an environment has the same need for resources (niche) as another, to survive.

Each organism has a specific place in the ecosystem called NICHE. A species' niche is basically its ecological role or the function to which it is especially suited, which is defined by the set of conditions, resources and interactions it needs or can use.

The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources) or to put it in another way, two species in an ecosystem are bound to compete when they share the same niche (need for resources).

How does the greenhouse effect work?

Answers

Gases in the atmosphere such as carbon dioxide do what the roof of a green house does. During the day the sunshines through the atmosphere. Earths surface warms up in the sunlight. At night, Earths surface cools, releasing the heat back into the air.

 
The greenhouse effect is when radiation from a planet's atmosphere warms the planet's surface to a temperature higher than what it would be without its atmosphere. If a planet's atmosphere has radiatively active gases the atmosphere will radiate energy everywhere
