1. Summarize the six ways the loss of Arctic ice is affecting everyone.
six ways are temperature,coastal communities,food,shipping,wildlife,permafrost
Answer:
Explanation:
Artic Ice are melting due to change in the climatic system as a result of global warming. The active increase in human activity resulting in global warming will continually perpetuate the decrease in artic Ice.
Artic heat help to balance temperature or heat on the earth surface by reflecting heat back into the environment. When the artic Ice is reduced, the amount of heat reflected is also reduces.
Coastal community - a continuous rise in ocean level can lead to flooding which will affect the coastal community surrounding the ocean. An the ocean has been incredible gradually over the pass decades.
Food - Reduction in the artic Ice car Lea to increase heat affect crop growth through damage by heat stresses leading to an increase price rate of food.
Meltng of Ice increase the shipping routes causing more harm through ship wrek.
Melting of Ice can leave to loss of animals that depends on it for survival.
Permafrost occurs when the ground is permanently block or frozen leading to accumulation of methane gases that causes global warming.

Predict which one of the following organisms will have the highest percentage of unsaturated fatty acid chains in their membranes: Group of answer choices thermophilic bacteria desert iguana humans antarctic fish
Answer:
Humans
Explanation:
Humans are bigger than most beings and some people are extremely obese.
The organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.
Unsaturated fatty acid chains have one or more double bonds, while saturated fatty acid chains do not contain any double bonds.When the temperature decreases, the composition of the phospholipids bilayer membrane becomes more unsaturated to be able to maintain different properties such as homeoviscosity.In consequence, membrane lipids exhibit the highest percentage of unsaturated fatty acid chains during cold acclimation.In conclusion, the organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.

The diffusion spot diameter with one crystal at 15 min ( mm) is 59 . The rate of diffusion with one crystal So how would I convert this 59 to ( mm/h)?
Answer:
This is straight forward.If there are 60 minutes in one hour, then to convert minutes to hours as requested, simply divide the number of minutes given by 60.Thus if you divided the 59 by 60 it gives you what?round the answer to whole number.
When there is a moment of any solute present in the solution from high concentration to low concentration area is called diffusion.
It will take 0.25 hours to diffuse one crystal.
This can be calculated by:
Given,
Time for one crystal diffusion = 15 minDiameter for one crystal diffusion = 59 mmIn 1 hour there are 60 minutes.
60 minutes = 1 hour.

O A. Paleozoic and Precambrian
O B. Mesozoic and Paleozoic
OC. Mesozoic and Cenozoic
O D. Cenozoic and Paleozoic
B. Mesozoic and Paleozoic eras ended with mass extinctions.
What is Mass extinctions?Mass extinctions are periods in Earth's history when a significant proportion of the planet's biodiversity is wiped out in a relatively short period of time.
These events have occurred several times throughout Earth's history, and they are typically associated with major geological and environmental changes.
The Mesozoic era, which lasted from about 252 to 66 million years ago, ended with the Cretaceous-Paleogene extinction event. This event was likely caused by the impact of a large asteroid or comet, which triggered a range of environmental changes, including wildfires, acid rain, and a nuclear winter-like effect.
The event is most famous for wiping out the dinosaurs, but it also resulted in the extinction of many other species, both on land and in the oceans.
The Mesozoic era ended with the Cretaceous-Paleogene extinction event, which wiped out the dinosaurs and many other species.
The Paleozoic era ended with the Permian-Triassic extinction event, which was the largest mass extinction in Earth's history, and resulted in the loss of approximately 96% of all marine species and 70% of land species.

Answer:
Gathering evidence.
Explanation:
Scientific evidence refers to the information obtained by research or observation.t This is the root of the scientific method because it's how an investigator evaluates different ideas, theories, or hypotheses. The mechanism of science involves explaining the phenomena we see in the world that match the data one has collected for the purpose. If one's theory doesn't match the evidence, then it needs to be revised. Therefore collecting evidence is a significant part of scientific investigation.
both ethanol and glycine are small molecules of approximately equal molecular weight. However, ethanol is much more membrane permeable than glycine. What accounts for the large difference in membrane permeability between ethanol and glycine
Answer:
Ethanol is a non polar molecule.Therefore it passes through the cells membrane easily by diffusion like other non polar like CO2 and water.However, glycine is an amino acid ( the simplest amino acid) a charged molecule /polar molecule/.it can not therefore pass through the bilayer by simple diffusion because of the phospholipid bi-layers. Therefore special transport proteins are needed for its passage across the cell membrane.
Example-GLYT 1 and 2 are the carrier proteins specific for glycine transport across the membrane.

geologist is studying a plate boundary indicated by the
arrow
Fill in the blank to complete the statement about the
plate boundary
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.

A receptor is a structure that detects stimuli. The stigma (eyespot) of Euglenoids detects ____, assisting with phototaxis. A. light intensity and direction B. vibrations C. chemicals D. sound frequency and direction E. temperature change
Answer:
The correct answer is option A, that is, light intensity and direction.
Explanation:
A photoreceptive organelle witnessed in the motile or flagellated cells of unicellular photosynthetic species like euglenoids and green algae is known as the stigma or the eyespot apparatus. It permits the cells of the organism to detect the intensity and direction of the light and react towards it.
This assists the organisms to either swim away from the light known as negative phototaxis, or to swim towards it known as positive phototaxis. The eyespots are the basic and the most typical eyes witnessed in nature. The eyespots comprise bright areas or orange and red granules of pigment and photoreceptors.

Assume that plant weight is determined by a pair of alleles at each of two independently assorting loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 4 g to weight and that each allele represented by a lowercase letter contributes 1 g to weight. If a plant with genotype AA BB is crossed with a plant with genotype aa bb, what weights are expected in the F_a progeny?
A. 1 g
B. 4 g
C. 8 g
D. 10 g
Answer: choice D. 10g
Explanation:
The cross is AABB x aabb so the F1 progeny would have AaBb genotype.
The question states that dominant alleles(uppercase letters) contribute 4g and recessive ones contribute 1g to the weight of the plant.
