An ecologist hypothesizes that predation by a particular owl species is the major factor controlling the population of a particular rabbit species. The first step in testing this hypothesis would be to determine

Answers

Answer 1

Answer:

The correct answer is - whether owl eats the rabbits.

Explanation:

A hypothesis is a proposed answer for an unexplained event that doesn't fit into the current acknowledged logical hypothesis. The essential thought of a hypothesis is that there is no pre-decided result.

The Hypothesis can be proved or disproved by scientific research that has various steps but initiailly testing the hypothesis is essential:

- Making assumptions.

- Stating the research and null hypotheses

- Selecting the sampling pattern and specifying the test statistic.

- calculating the test statistic.

-Making a decision and interpreting the results.

Thus, the first step after forming a hypothesis is to check or test the hypothesis which is null hypothesis -whether owl eats the rabbits.

A storm brings two formerly separated populations of beetles together. They look very similar. Under the biological species concept, which of the following would show that the two populations are different species?
A. One population breeds in spring, the other in fall.
B. Males of the two populations have different flight patterns in courtship.
C. When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch.
D. All of the above is correct.
E. None of the above is correct.

Answers

Answer:

The correct option is D: All of the above is correct.

Explanation:

The biological species concept says that species are population groups that, in a real or potential way, can reproduce among each other and that are reproductively isolated from other groups.

Individuals belonging to a species cannot mate with members of other species, and if they do there is not any reproductive success.    

The mechanisms of reproductive isolation might be divided in prezygotic and postzygotic.

Prezygotic or Premating mechanisms:

Ecological or due to habitat isolationSeasonal or temporal. This is the case described in option A "One population breeds in spring, the other in fall". These species are reproductively isolated because they differ in their breeding season.Sexual or ethological. This is the case described in option B "Males of the two populations have different flight patterns in courtship". Males belonging to each species behave differently during courtship. MechanicalGametes incompatibility

Zygotic or Postmating Mechanisms:

Hybrid inviability. This is the case described in option C which states that "When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch". Eggs fail to hatch because the zygote is inviable. Hybrid sterilityHybrid decreased fertility

How do you think pollination takes place in flowering plants?

Answers

Answer:

My answer is down below.

Explanation:

Pollination occurs when the transfer of pollen grains from the anthers to the stigma of a flower of the same species take place. After reaching the stigma of the flower of the same kind of plant, the pollen grains absorb moisture from the stigma surface and begins to grow a tube. This tube is called the pollen tube.

Explanation:

insects typically pollinate flowers as they move from plant to plant searching for food. when an instects lands on a flower to feed, pollen grains sticks to its body. As the instects moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs.

All living things are made up of one or more cells, which is one of the three principles of the cell theory. The fundamental unit of structure and organization in organisms is the cell.

While doing studies on tissues in the late 1830s, zoologist Theodor Schwann and botanist Matthias Schleiden proposed the united cell theory.

The unified cell theory states that each living thing is composed of one or even more cells, every cell is the basis of life, and new cells can be created from existing cells.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.

Answer:

Many individuals consider that Archaeopteryx would have been the first bird, however, many paleontologists are against it. The findings of many fossils of Archaeopteryx have revealed that though the creature exhibited wings, the majority of its characteristics were of reptile, like the existence of full teeth set. Apart from this, the wings formation of the creature demonstrated that it was not completely capable of flying.  

No matter what, the presence of wings makes them closely associated with the modern time birds. Thus, it can be concluded that Archaeopteryx could be considered as an intermediate between the reptiles and the birds and is a precursor to the modern-day birds' evolution.

The graphic shows the citric acid cycle. A diagram of the citric acid cycle is shown. Acetyl C o A enters the citric acid cycle and combines with a 4-carbon compound to form citric acid. During the citric acid cycle, what happens to acetyl-CoA? It enters the citric acid cycle and gains carbon dioxide to form citric acid, and gains more carbon dioxide through redox reactions to form a 4-carbon molecule. It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule. It enters glycolysis and associates with a 5-carbon molecule through redox reactions, forming another acetyl-CoA molecule. It enters the citric acid cycle and associates with a 4-carbon molecule, forming a 5-carbon compound, and then through oxidation reactions regenerates the 4-carbon molecule.

Answers

Answer:

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

Explanation:

Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)

In the citric acid cycle, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).

--------------------

The resumed steps of the Citric acid cycle are as follows,

1) Acetyl CoA joins an oxaloacetate molecule, which is a 4C molecule. They release the CoA group and form a 6C molecule called Citrate.

                      Acetil CoA + Oxalacetato → Citrato + CoA group

2) Citrate turns into an isomere Isocitrate

3) Isocitrate oxidates and release 1 CO₂ molecule, producing an α- ketoglutarate molecule -this is a 5C molecule-. Meanwhile, NAD+ reduces to NADH.

                    Isocitrate + NAD+ → α-cetoglutarate + CO₂ + NADH

4) α-ketoglutarate oxidates and release 1 CO₂ molecule, producing a 4C molecule, which joins a Coenzyme A producing Succinyl-CoA. Meanwhile,  NAD+ reduces to NADH.

          α-cetoglutarate + NAD+ → 4C molecule + CO₂ + NADH

          4C molecule + Coenzyme A → Succinil-CoA

5) CoA from Succinyl-CoA is substituted with a phosphate group, which then forms ATP. The final product is Succinate and ATP

       Succinyl-CoA + Phosphate group + ADP → Succinate + ATP + CoA

6) Succinate oxidizes and forms Fumarate, a 4C molecule. FAD+ forms FAH₂

                     Succinate + FAD+ → Fumarate + FADH₂

7) A water molecule and Fumarate produce Malate, which is another 4C molecule

                                Fumarate + H₂O → Malate

8) Finally, malate oxidizes and oxalacetate regenerates -the initial 4C compound-. NAD+ reduces to NADH.

                     Malato + NAD+ → Oxalacetate + NADH

So, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).
