A macaw is a type of parrot with colorful feathers that flies about in the upper canopy of trees in tropical rainforests. Macaws have a diet which includes
fruits, leaves, nuts, and seeds of plants. Which of the following describes a biotic factor of the macaw's habitat that provides a survival advantage for
these birds?
o
The colorful feathers are lost and regrow each year
0
Some rainforest predators are able to climb trees
o
Trees provide shelter and a macaw
Answer:
Trees provide shelter
Explanation:
Firstly, a biotic factor refers to the living component of an ecosystem including the plants, animals and microbial species of one another. According to this question, a macaw is a type of parrot with colorful feathers that flies about in the upper canopy of trees in tropical rainforests. Macaws have a diet which includes fruits, leaves, nuts, and seeds of plants.
In order to ascertain that this birds species are in survival advantage, trees, which is one of the biotic factors found in the tropical rainforest, provide shelter for these birds.
Describe an example of the scientific method. Include any limitations this method has.
The enzyme could become spatially distorted, thus reducing the ability of the active site to catalyze the reaction. Tight enzyme-substrate binding will reduce the forward rate constant for the reaction. Tight binding of the enzyme to its substrate will pull the substrate out of solution, thus decreasing the driving force for the forward reaction. Tight binding of the enzyme to its substrate will result in the enzyme-transition state complex being higher in energy than with weaker binding. All of the above.
Answer:
All of the above.
Explanation:
All the given options are the potential disadvantage of an enzyme that have a very high affinity for its substrate.
The enzyme can be distorted spatially and thus reduces the ability to catalyze the reaction of the active site.
The tight binding of an enzyme to a substrate results in enzyme transition state complex which is higher in energy.
The tight binding also pulls the substrate out of the solution and decreases a driving force in the forward reaction.
Which of the following is not associated with the parasympathetic division of the autonomic nervous system (ANS)?
a. resting.
b. energy conservation.
c. emergency action.
d. digesting.
Answer:
a
Explanation:
The autonomic nervous system (ANS) is involved in breathing and heartbeat. Emergency action is not associated with the parasympathetic division of ANS. Thus, option c is correct.
What is ANS?ANS is abbreviated for the autonomic nervous system and is a sub-division of the peripheral nervous system. It includes actions that do not require consciousness and can regulate involuntary actions.
The ANS is sub-divided into sympathetic and parasympathetic nervous systems. The latter division is involved with resting, energy conservation, and digestion. It regulates the various body functions.
Parasympathetic nervous systems regulate the breathing rate, digestion, heartbeat, and blood flow, as they all are involuntary physiologic processes. They even show acute stress response but not emergency actions.
Therefore, option c. the emergency responses are not associated with parasympathetic nervous systems.

Some blackcaps that migrate to the United Kingdom have become distinguishable by certain physical and behavioral traits from blackcaps that migrate to Spain. What best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter?
Answer:
Increases.
Explanation:
There is a good effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter because there is more food available for the blackcap bird which automatically increase the population of the bird. Food is the main factor that contributes in the increase or decrease population of blackcap in the United Kingdom and prevent the removal of this bird in that environment.

Which kind of rock is most likely to contain a trilobite fossil?
1) sedimentary
2) igneous
3) metamorphic
4) plutonic
Explain how it formed. Thank you.
Answer:
1) sedimentary
Explanation:
Sedimentary rocks are formed by the accumulation and subsequent compression of sediments (i.e., minerals and once-living organisms known as fossils) on the Earth's surface. Almost all fossils are found within sedimentary rocks. Some examples of sedimentary rock that contain fossils include limestone, mudstone and shale. Rock layers are known as strata. The oldest layers containing the once-living organisms (which were fossilized as they formed) are found at the bottom, while the youngest layers are found at the top.

In the human body, is every organ a part of only one organ system? Or are some organs a part of two or more organ systems?
Answer:
I feel like in most cases, every organ in the organ system has only one specific function. But some organs may be a part of one or more organ systems. For example, the liver is a part of the digestive system but also plays an important role in the excretion system.

Heterogéneas.
Explanation:
Se denomina "heterogénea" a toda aquella cosa que, por sus características particulares, no puede ser asimilada a otras sino que posee una individualidad particular que impide dicha asimilación. Así, por ejemplo, una piedra y una canica son heterogéneas entre sí, en tanto no poseen las mismas características y por lo tanto son claramente diferenciables.

The enzyme choline acetyltransferase catalyzes the reaction between acetyl-CoA and choline resulting in the formation of the neurotransmitter acetylcholine. This enzyme is produced within the cell body of neurons, but the synthesis of acetylcholine occurs within the axon terminals. What best describes the axonal transport mechanism associated with this process?
Answer: Anterograde direction.
Explanation:
Choline acetyltransferase is an enzyme made in the body of a neuron and that needs to be transferred to the axon terminal to perform its function. Its function is to bind acetyl-CoA to choline to form the neurotransmitter acetylcholine.
The movement toward the cell body is called retrograde transport and the movement toward the synapse is called anterograde transport. So, since it is produced in the body of the cell and it has to go to the axon terminals, the choline acetyltransferase is transported in the anterograde direction.
This type of transport is responsible for the movement of organelles such as mitochondria, lipids, synaptic vesicles, proteins from a neuron cell body through the cytoplasm of its axon called the axoplasm. Because axons can sometimes be meters long, neurons cannot rely on diffusion to carry products to the end of their axons. Dynein is a motor protein involved in this retrograde axonal transport. Its light chains bind cargo, and its globular head regions bind the microtubule, "moving forward" along it.
What are the scientists doing incorrectly? What could they do to make their work in the lab safer? Why is it important to follow these procedures? Part A
Answer:
Part A
The scientists threw away their instructions. They should have kept their instructions to properly and safely follow all procedures. Following instructions also ensures useful experimental results.
Part B
The scientist is not wearing safety goggles. He should wear goggles during activities that can harm his eyes. Working safely to avoid injury is every scientist’s job.
Part C
The lab area is messy and needs better organization. The scientist should carefully store the test tubes that aren’t being used. A clean work area helps scientists work safely and efficiently to avoid costly accidents.
Part D
The scientist is disposing of dangerous materials incorrectly. He should have followed disposal instructions as described in the lab procedure. Improper disposal can pollute the environment, harm fragile wildlife, and damage facilities. Scientists must be environmentally responsible.
Part E
The scientist didn’t clean up after an accident. He should have disposed of the glass immediately after it broke rather than waiting. Accidents create hazards for scientists and those around them.
Part F
Scientists should not eat or drink in a lab area. They could swallow something harmful or foul. Snacks and meals should be eaten during designated breaks and never near the lab area.
