Rovers that move too slowly.
The Impediments that a rover would face while exploring and collecting samples on Mars are :
Mechanical failure Collision Reduction/breaking down of mobility Slow movement of RoverRovers are exploration devices that are used to collect samples/information about a terrain ( mostly in space like Mars ) and some of the samples they collect include : dust, sand and rocks.
Some of the technological impediments face by space rovers includes: mechanical failure ( the failure of rover to work efficiently due to wear and tear or other mechanical factors. )
The Rovers can collide with each other or even human due to force of gravity. the degradation of mobility is another physical impediments while the slow movement of the Rover in Mars due to gravitational forces is considered a physical impediment.
Hence we can conclude that some of the physical and technological impediments faced by Rover are : Mechanical failure, Collision, Reduction/breaking down of mobility ,Slow movement of Rover

PLEASE HELP ASAP!! How neurotransmitters carry nerve impulses across the synaptic cleft
Answers
Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron
Another way of thinking is
Neurons talk to each other across synapses. When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine)
Hope this helps =)
Explanation: Neurotransmitters like to travel across the synapse between the axon and the dendrite of the next neuron. They then attach to the membrane of the dendrite. This connection makes it possible for the nerve impulse to travel through the receiving neuron.

Carbonic anhydrase is an enzyme found in the cytoplasm of a cell. You genetically modified the gene which produces the mRNA for carbonic anhydrase to now include a signal sequence. What will happen when carbonic anhydrase initially binds to a ribosome
Answers
Answer:
Explanation:
Carbonic anhydrase modification is a promising strategy for improving the potency and stability of carbonic anhydrase, which is used to expedite CO2 uptake from flue gases. Carbonic anhydrase can be genetically engineered to increase CO2 conversion, absorption of CO2 from a gaseous state into bioactive compounds, and mineral synthesis.
When carbonic anhydrase attaches to a ribosome, the carbonic anhydrase will now be synthesized at first by the free ribosome, after which the ribosome will become a bound ribosome and the protein will be present in the rough Endoplasmic reticulum when the synthesis is complete.
In this case, when carbonic anhydrase initially binds to a ribosome - Carbonic anhydrase initially will be synthesized by free ribosomes, but then these ribosomes then will become bound ribosomes and the protein will be in the rough ER when synthesis is complete
Carbonic anhydrase is an enzyme that helps the rapid conversion to carbonic acids from carbon dioxide and water with protons and bicarbonate ions.
Classified as a metalloenzymeThe modification in the carbonic anhydrase enhances the potency and stability of the enzyme.It can be modified to increase CO2 conversion, absorption of CO2 from a gaseous state into bioactive compounds, and mineral synthesis.Thus, In the case of carbonic anhydrase bound to a ribosome, at first, the carbonic anhydrase will be synthesized by the free ribosome and later the ribosome will become a bound ribosome and the protein will be present in the rough Endoplasmic reticulum once the synthesis process completes.

5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained
Answers
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.

3. Explain how you would tell if one growing season was more favorable for growth than others.
4. How can you determine the past arrangement of leaves on a bare twig?
Answers
Answer:
A herbaceous dicot has vascular bundles arranged in a ring around the pit, we're at a herbaceous monocot has vascular bundles scattered throughout the stem. Or herbaceous dicot has vascular cambium between xylem and phloem, whereas a herbaceous monocot usually lacks vascular cambium.
Monocot stems have scattered vascular bundles. Dicot stems have their vascular bundles in a ring arrangement. Monocot stems have most of their vascular bundles near the outside edge of the stem. Dicot roots have their xylem in the center of the root and phloem outside the xylem.
The arrangement of xylem and phloem is different in dicots than it is in monocots. The xylem is all located in the middle of the dicot root, and bundles of phloem are arranged around it, separated from it by vascular cambium. Monocots do not have vascular cambium.

Manatees and seals both share some phenotypic similarities that are adaptations to an aquatic environment. However, seals evolved from a bearlike carnivore and manatees evolved from a hoofed mammal. This example shows that __________.
a. evolution is not always unidirectional.
b. evolution can occur rapidly for one species while the other species stays relatively unchanged.
c. similarity is a good predictor of how long it has been since two species shared a common ancestor.
d. evolution is not always divergent.
Answers
They are about as different as a leopard and a cow.
Meaning both are mammals of roughly similar size, and sharing a vaguely similar habitat. That’s the end of similarities.
Seals are carnivorous and manatees are plant eaters, and taxonomically they are in different orders. Seals spend much of the time on land, while manatees are completely aquatic. Seals have thick layer of fat and are adapted to Arctic water, while manatees, despite their roly-poly appearance, have almost no fat and do not handle cold water well at all. Here is the closest a manatee ever gets to an iceberg.

An enlarged right ventricle both increases oxygen intake and the risk of pulmonary hypertension. How can natural selection
result in an adaption that produces both positive and negative effects?
A) The positive effects appear after reproductive age in certain environments.
B) The positive effects outweigh the negative effects in certain environments.
C) The negative effects appear later in life in certain environments.
D) The negative effects appear before reproductive age in certain environments.
Answers
Answer: B
Explanation: I took the quiz on my own and got a 100%
The positive effects outweigh the negative effects in certain environments. Therefore, option (B) is correct.
What is natural selection?In certain environments, an enlarged right ventricle can be advantageous for increasing oxygen intake, such as at high altitudes where there is less oxygen in the air. However, in the same environment or in other environments, an enlarged right ventricle can increase the risk of pulmonary hypertension, which can lead to heart failure.
Natural selection can result in an adaptation that produces both positive and negative effects if the positive effects outweigh the negative effects in certain environments. This can result in the adaptation being favored by natural selection and becoming more common in the population. Over time, this can lead to the adaptation becoming a fixed trait in the population.

A difference between a Class I and a Class II tRNA synthetase is (select all that apply):
a. the Class I synthetase reaction requires a transesterification reaction not necessary in the Class II reaction.
b. the Class I synthetase uses the 2' OH of the 3' end of the tRNA as a nucleophile and the Class II uses the 3' OH.
c. the Class I synthetase requires ATP as a cofactor and the Class II does not.
d. the Class II synthetases are typically monomeric, whereas the Class I enzymes frequently function as multimeric protein complexes.
Answers
Answer:
Option b is the correct answer.
Explanation:
The 2' OH of each 3' end of the tRNA is used as a nucleophile by Class I synthetase, whereas the 3' OH is used by Class II.
The Class I aminoacyl-tRNA synthetase attaches amino acids to the 2'-OH group of the tRNA's 3'-end ribose residue, whilst the Class II synthetase attaches amino acids only to the 3'-OH group of the tRNA's 3'-end ribose residue. Both Class I and Class II enzymes conduct the transesterification process and the need of ATP.
What we have is option d is incorrect because, Class I enzyme is typically monomeric, while the Class II enzyme is dimeric or multimeric in nature.
