________ can harvest the energy they need through photosynthesis or other processes. Group of answer choices Plants Oligotrophs Autotrophs Cells Heterotrophs
Answers
Autotrophs have the ability to harvest the amount of energy they need through photosynthesis or other processes.
What is photosynthesis?Photosynthesis refers to a biological and chemical process through which autotrophs (green plants) transform light energy (sunlight) into chemical energy.
In Science, the chemical reaction or equation for photosynthesis is given by:
\(Carbon \;dioxide + water + light energy \rightarrow sugar + oxygen\)
In conclusion, autotrophs have the ability to harvest the amount of energy they need through photosynthesis or other processes.

Which sectioning technique would cut the wrist cleanly away from the shoulder at the elbow?
Answers
Which relays instructions from the CNS to muscles more quickly, the somatic nervous system or the ANS? The somatic motor system relays instructions to muscles more quickly because it involves only one motor neuron, whereas the ANS uses a two-neuron chain. Moreover, axons of somatic motor neurons are typically heavily myelinated, whereas preganglionic autonomic axons are lightly myelinated and postganglionic axons are nonmyelinated.
Answers
The somatic motor system relays instructions to muscles more quickly because it involves only one motor neuron, whereas the ANS uses a two-neuron chain. Moreover, axons of somatic motor neurons are typically heavily myelinated, whereas preganglionic autonomic axons are lightly myelinated and postganglionic axons are non myelinated.
The lateral component of the somatic motor system controls the premotor interneurons and motoneurons of the distal muscles. This component consists of two pathways—the lateral corticospinal and the rubrospinal pathways. In humans, the lateral corticospinal pathway subserves the control of the independent movements of the extremities. It controls the motoneurons via direct projections as well as indirectly via strong projections to the laterally located premotor interneurons.
The motoneurons innervating the muscles of the distal limbs receive the strongest direct projections from the motor cortex. This descending system enables humans to make most refined and extremely complex movements, such as independent finger movements and speech, the most complicated motor performance. In most mammals, both the lateral corticospinal and the rubrospinal pathways are important, but in humans the rubrospinal pathway seems to be irrelevant. The somatic motor system relays instructions to muscles more quickly because it involves only one motor neuron, whereas the ANS uses a two-neuron chain. Moreover, axons of somatic motor neurons are typically heavily myelinated, whereas preganglionic autonomic axons are lightly myelinated and postganglionic axons are non myelinated.

Claim:
Answers
Amphibians are cold-blooded animals that are born in water and breathe through gills as larvae, but then develop lungs and live on land as adults. They also have smooth, moist skin and lay their eggs in water.
Reptiles, on the other hand, are also cold-blooded, but they are born on land and breathe through lungs throughout their lives. They have scaly skin and lay their eggs on land.
Alligators belong to the class Reptilia, along with other animals such as turtles, snakes, and lizards. Therefore, the chart that lists the alligator as an amphibian is incorrect and needs to be revised to reflect the correct classification of the animal as a reptile.
How is carbon

environment?
Answers
Answer:
Carbon dioxide from the air is used to produce food for plant growth. Carbon moves from plants to animals when animals eat the plants. Also, Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere.
The burning of fossil fuels also releases carbon dioxide into the atmosphere.

How does the water vascular system allow an echinoderm to move along the ocean floor?
Answers
Answer: Sample Response: Water gets into the water vascular system through an opening in the echinoderm's body. When the animal contracts its muscles, the water is forced through the system and into the tube feet. The tube feet act as suction cups, gripping the surface below. When the echinoderm retracts its muscles, the tube feet retract and let go of the surface. This series of contractions and retractions allows the animal to move along the ocean floor.

Suppose the 3' splice site is mutated from AGG to ACG. Predict the consequence of this mutation. Choose one: A. Splicing would occur as normal because this splice site is less important than the 5' splice site. B. Splicing would occur as normal but there would be a point mutation in the mRNA and final protein sequences. C. Splicing would not begin if the 3' splice site is altered. D. Splicing would begin but not be properly completed if the 3' splice site is altered.
Answers
Solution :
The correct order of the RNA splicing is :
1. The BBP and the U2AF is to bind the A in branch point site in the intron, but the U1snRNP binds the 5' splice site.
2. U2snRNP helps to bind the branch point site while U4/U6 and the U5snRNP binds the 5' slice site.
3. 5' end of intron binds branch point adenine and forms a lariat.
4. Conserved adenine in branch point site attacks 5' splice site thus cutting the RNA at 5' splice site.
5. Lariat is released and then degraded.
6. The 3' end of first exon interacts with 3' splice site and forms a new bond in the sugar phosphate backbone.
When the 3' splice is altered, then the splicing begins but are not properly completed due to the altered activity of the full introns that will be present in mRNA.

which is more resistance? fungi endosporesstaphylococccus bacteriatuberle bacilli
Answers
From all the options given, the one that has the greatest resistance are endospores. Endospores have several outer coats that protect them from dessication, temperature changes, and even from UV radiation. Endospores are the response to environmental hostility, therefore when a bacteria senses abiotic adversity it starts to deploy the mechanisms to create an endospore, which is the resistant form of the microbe. Fungi, and the other bacterias mentioned are capable of developing spores, but these organisms themselves are more vulnerable than a endospore.

The state of a medium helps determine the speed of sound passing through medium
Answers
True. The speed at which sound travels through a medium is determined by the properties of that medium.
What do you mean by sound?
Sound is a type of energy made by vibrations that travel through the air or another medium, like water. It is sensed by our ears and interpreted by our brains. Sound is made up of waves that have different frequencies, which determine the pitch and loudness of a sound.
Factors such as temperature, pressure, composition, and density can all affect the speed of sound in the medium. For example, sound travels faster through warmer air than through colder air, and faster through denser materials than through less dense materials.
Hence, the statement is True.

In the graph above, which letter represents the activation energy (EA) of a reaction without an enzyme and why?
ANSWER: CORRECT (SELECTED)
X; the activation energy (EA) is greater in an uncatalyzed reaction
EXPLANATION:
The X label on the graph represents a larger EA "hump" (as compared to Y). The increased steepness of this hump is due to the lack of an enzyme, making this an uncatalyzed reaction.
Answers
The activation energy of the reaction without an enzyme is represented as X.
What is activation energy of a reaction?Activation energy of a reaction is the minimum energy that reactant molecules must possess in order to effectively collide to form products,
The activation energy of a reaction depends on the bond energies of the reactants.
Given an energy profile diagram, the activation energy is represented as EA.
In the diagram, the activation of the reaction without an enzyme is X because it the activation energy of an uncatalyzed reaction is greater than the activation energy of a catalyzed reaction.
In conclusion, activation energy is greater for an uncatalyzed reaction.

Answer:
The correct answer is D.
Vascular tissue, chloroplast, cuticle, flowers, seeds.
Vascular tissue and chloroplasts are the most primitive characteristics in the table, and so should be at the top of the cladogram.
