Lana was walking down the sidewalk looking at her phone and didn't notice the curb ahead. As she tripped her ankle turned inward (inversion). She heard a pop and had pain on the lateral side (outside) of her ankle and foot. Lana went to urgent care and was diagnosed with a 2nd degree lateral ankle sprain and fracture of her fibula (lateral bone in the lower leg). List all the types of tissues that have been affected by this injury. Which will likely heal slower, ligament or bone?
Answer:
ligament bcos ligament heal before bone
A ligament tear is an injury caused by an extreme motion, like a forceful twisting of a joint. A tear usually causes immediate pain and perhaps even a "pop" sound at the site of injury when it occurs. Depending on the severity of the injury, the affected site may become unstable.
What is Ligament?Ligaments are elastic bands of tissue that connect bones to each other and provide stability and strength to the joint. The four main ligaments in the knee connect the femur (thighbone) to the tibia (shin bone) and include the following: Anterior cruciate ligament (ACL).

Which statement about enzymes is true?
An enzyme functions to increase the activation energy in a reacton.
Enzymes are proteins that function as catalysts in nonliving things.
Each enzyme can catalyze many different biochemical reactions.
Enzymes and substrates fit together like a lock and key.
Answer:
Enzymes and substrates fit together like a lock and key since, in one enzymatic reaction, only the correct substrate (i.e., the key) binds to its corresponding enzyme (i.e. the lock).
Explanation:
An enzyme (or catalyst) is one protein that has catalytic functions, being therefore capable of accelerating chemical reactions. The enzymes are known to control the rate of these chemical reactions (i.e., catalysis) without suffering alterations during these processes. Thus, the enzymes are proteins that catalyze chemical reactions that are not favored under normal conditions. Moreover, one enzyme may catalyze more than one chemical transformation, as well as the same reaction may be catalyzed by two or more enzymes.

A channel protein specific for calcium ions was found to have a pore lined with six glutamate residues that participate in coordinating the calcium ion. What would happen to the selectivity of the pore if the Glu residues were mutated to Asp residues
Answer:
If the mutation takes place, then the shorter side chains of asp compare to Glu will affect the permeability of the transport protein to calcium ions. Specifically, the mutation will increase the sizes of the pore,which in turn decreases the selectivity for calcium ion. Hence this affect excitability of the cell.

O C. Urethra
D. B cell
Answer:
Lymphocyte is a B cell ans - option DExamination of a sandstone outcrop reveals an abundance of feldspar and quartz grains. Could this weathered material have come from a nearby basaltic lava flow or a granite outcrop up the road?
The weathered material of a sandstone outcrop revealing an abundance of feldspar and quartz grains would have come from a granite outcrop up the road rather than a nearby basaltic lava flow.
Feldspar is a common mineral found in granite, whereas it is less abundant or absent in basaltic lava flows. Granite is composed primarily of feldspar along with quartz and other minerals. So, the presence of an abundance of feldspar grains suggests a connection to granite rather than basalt.
Quartz is present in both granite and basalt, but it is more commonly associated with granite. Quartz is one of the major constituents of granite, whereas it is generally less abundant in basaltic lava flows. Therefore, the presence of quartz grains does not necessarily differentiate between the two sources but aligns more with the possibility of granite as the origin.

This boundary is between the African Plate and the
Plate
Answer:
Its Eurasian
Explanation:
This boundary is between the African Plate and the Eurasian Plate.
This boundary is known as a convergent plate boundary. Convergent plate boundaries occur when two tectonic plates move toward each other.
In the case of the African Plate and the Eurasian Plate, they are colliding, and one plate is being forced beneath the other in a process called subduction.
As the plates converge, the intense pressure and friction cause seismic activity, leading to earthquakes and volcanic eruptions in the region.
These collisions also result in the formation of mountain ranges, such as the Himalayas, as the crust is pushed upward and folded.
Studying this convergent plate boundary is essential for understanding the geological processes shaping our planet's surface and the associated hazards like earthquakes and volcanoes.

In perspective, with Earth being 4,500,000,000 years old and humans being around 1,400,000 years; how long out of a 24 day time period have we as humans been here.
Answer:
Day time period have we as humans been here: 26 seconds
Explanation:
4,500,000,000 years = 1 day
1,400,000 years = X
X = 0.0003111
1 day = 86,400 seconds
0.0003111 = X
X = 26 seconds
In term of the Earth in 24-hour clock, Homo sapiens appeared on our planet only in the last 26 seconds, it means that in geologic time, humans have existed for only a brief time period and thereby it is a relatively new species.

Explain the plasma membrane in easy way.
Answer:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.[

It has been stated that the rainforests owe their existence at least in part to bats.
Is this a valid statement and why or why not? Defend your answer.
Answer: Valid Statement ✓
Explanation:
Bats have been known to contribute to the growth and restoration of Tropical Rainforests in 2 main ways. Seed Dispersal and Pollination.
Seed Dispersal.
Fruit Bats in the Tropical Rainforest are responsible for a lot of seed dispersal. Feeding at night to avoid predators, they eat fruits from various trees and then defecate these seeds after digestion. Fruit Bats like most other bats are very strong fliers and so cover a whole lot of distance at night meaning that they give the seeds a very wide coverage. Indeed it has been shown that because they defecate the seeds, the seed already has fertilizer to get nutrients from as it grows thereby increasing it's growth rate.
There are also trees and plants that have evolved to grow spiky or sticky fruit that attach themselves to the Bats which then deposit them elsewhere as they fly.
Pollination.
Fruit Bats have specialized long tongues to sip nectar from flowers. When they do this they pollinate the flowers. It has even been shown that some plants evolved to have brighter colours so as to attract these bats to enable pollination to happen. Indeed research shows that more than 125 genera of tropical plants rely on bats for pollination.
Bats plays an essential role in the existence of rainforests, they help to replenish and expand the area of rainforests.
The importance of bats:Bats plays an essential function in the existence of rainforests. Along with the birds they assist in some of the major activities like replenishing the devastated region and expanding the region of rainforests. It is known that the majority of the tropical plants are dependent upon the methods of seed dispersal for expansion of rainforests.
Apart from this, restoration of rainforests is also dependent upon the fruit-consuming animals like bats. Bats helps to disperse the shrub species to the gradually regenerating barren landscapes or grasslands or rainforests, which got devastated. It has been found that about 90 percent of the pollination and dispersal of seeds in rainforests is done with the help of species like bats.
The bats can assist in regenerating the deforested areas in short span of time in comparison to any modern strategies. Therefore, bats helps in afforestation of rainforests. Due to their aerial nature, they possesses the tendency to cover wide region and plays significant role in dispersal and pollination.
Thus, bats are essential for the existence of rainforests.

(e) Predict the effect of the removal of the final electron acceptor on the rate of carbon fixation by the chloroplast. Justify your prediction
Answer:
The ATPs produced during Chemeiosmosis, in the chloroplast is needed during Calvin cycle to fix carbon for production of CHO, protein and fats during conversion of 3C-glyceride phosphate(GP) to 2C- triose phosphate.(TP) .
The ATPs is needed for this reduction to take place in the presence of NADPH(which is oxdized to NADP).
Therefore, if the final electron acceptor is removed, there will be no electron transport chains which generated the PMF, for pumping H+ across into the thylakoid membrane of the chloroplast, to generate the electrochemical gradients, needed for the energy for ATPase synthase enzymes,to synthesize ATPs production.
Therefore, the removal of the electron acceptor (oxygen) leads to stoppage of electron transport chain, and hence loss of ATP s, and therefore, no Carbon fixation as CHO, or protein, or fats.
Explanation:
