Which eras ended with a mass extinction?
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.

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.

Suppose Stephen breeds snakes and wants to optimize production of offspring with both black bodies and brown eyes, which are coded for by two genes with the recessive alleles b and e, respectively. In snakes, B codes for brown bodies and E codes for red eyes. Stephen crosses two heterozygotes that produce 544 offspring. How many of these 544 offspring are predicted to have both black bodies and brown eyes?
Answer:
34
Explanation:
B codes for brown bodies.
E codes of red eyes.
b and e together code for black bodies and brown eyes.
Heterozygous brown body snake would have the genotype Bb.
Heterozygous red eyes would have the genotype Ee.
Individuals that are heteozygous for both trait would have the genotype BbEe.
Crossing two heterozygous individuals:
BbEe x BbEe
Progeny:
9 BBEE
3 B_ee
3 bbE_
1 bbee
Recall that black bodies and brown eyes requires be, hence the ratio of the progeny with black bodies and brown eyes is 1/16.
If the total number of offspring produced is 544, the number predicted to have black bodes and brown eyes would be:
1/16 x 544 = 34
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.
Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation allow for the change of gene pools over time
OPTIONS:
A) biogeographic isolation affects the random changes that take place within gene pools
B) biogeographic isolation affects the changes in gene pools that result from which organisms are breeding
C) biogeographic isolation determines who will win competition for mates
D) biogeographic isolation determines the time that populations will breed
Answer:
A) biogeographic isolation affects the random changes that take place within gene pools
Explanation:
Organisms can become splitted and isolated from each other by biogeographical factors, thereby preventing the isolated population of species from interbreeding with each other. When this occurs, the isolated population, over time, evolve separately and later become distinct from each other leading to a change in the original gene pool.
Biogeographical factors uch as habitat isolation can cause a change in the original gene of a species population which have now become isolated geographically, and thus, evolve separately.
Which is a factor that determines whether a molecule can cross a cell membrane?
Answer:
if a molecule is too large it cannot pass. also it depends on the concentration of a specific substance inside the cell. similarly, if a molecule is polar it cannot penetrate the phospholipid bilayer.
there are proteins that work as channels and pumps that allow these molecules to pass
Explanation:
The polarity of the molecule determines whether a molecule can cross a cell membrane. The correct option is D.
What is polarity?The asymmetric establishment of several cellular components, such as the plasma membrane, cytoskeleton, or organelles, is alluded to as cell polarity.
The polarity of the molecule determines whether a molecule can cross a cell membrane as the cell membrane is composed of phospholipids which are polar in nature.

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.
Name the mandibular motion resulting from the following combinations of muscle contractions: ________
a) B Masseter, B Temporalis, B Medial Pterygoid
b) L Lateral Pterygoid, R Masseter
c) B Lateral Pterygoid, B Medial Pterygoid
d) B Lateral Pterygoid, B Digastric
Answer:
c) B Lateral Pterygoid, B Medial Pterygoid
Mandibular motion is by combinations of B Lateral Pterygoid, and B Medial Pterygoid contraction which controls the mandible's closure, hence option c is correct.
What are muscle contractions?There are several of these, including the masseter and temporalis muscles, which control the mandible's closure; the medial pterygoid muscle, which controls the mandible's closure and lateral movements.
The lateral pterygoid muscle, controls the mandible's opening, deviation to either side, and anterior movement.
The lateral pterygoid muscles on the side that is contralateral to the excursion are contracted to move the jaw to one side (laterotrusion), with the help of the posterior temporalis muscle on the same side (ipsilateral).
Therefore the combination of B Lateral Pterygoid, and B Medial Pterygoid creates mandibular motion, hence option c is correct.

Answer:
OA
Explanation:
Chemical energy refers to the energy that is released with reactions involving chemicals. Cellular respiration takes glucose(a five carbon sugar) and breaks it down using glycolysis, then makes ATP(adenisine-triphosphate)(an essential chemical to the energy of life) using the krebs cycle and the electron transport train. This is all to get a surplus ATP, which is a useable CHEMICAL ENERGY source. This energy can be diverted to any system in the body, including the muscular system. Then, the muscles are used MECHANICALLY(look at the types of muscle levers in anatomy) to acheive work, thanks to the CHEMICAL ENERGY produced in cellular respiration. Thus, the answer in OA.

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.
so for AaBb we would have 4+1+4+1=10g.

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.

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.

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.
