After the 2004 tsunami disaster in Asia, there were reports that trained elephants had moved away

from the coastline before the tsunami struck. Scientists wondered if elephants had sensed the oncoming wave and the earthquake that created it. Elephant trunks have two kinds of nerve endings that are sensitive to pressure differences, but little is known about nerve ending distribution in the elephant's skin or feet. An elephant has recently died at a nearby zoo and scientists have decided

to dissect one of its feet to search for any special nerve endings. Results show a high density of pressure-sensitive nerve endings in the front of the foot and along the edges, which supports the

idea that elephants are sensing seismic signals produced by such disasters as earthquakes.


1. Independent variable

2. Dependent variable

4. Constant

5.controls

6.hypothesis

7. Sample size

8. Presence of repeated measures

Answers

Answer 1

Answer:

In the given dissection for the finding of the idea that elephant can sense the seismic signals generated by natural disasters are as follows:

Independent variable: it is the variable which influences the dependent variable or the dependent variable depends on. Here the area of the feet that is chosen to be dissected is the independent variable.

Dependent variable: It is the variable that is manipulated or influenced by the independent variable, in this dissection the sensitive to the pressure, nerve ending in the selected area of the feet.

Constants: It is a variable that remains constant or fixed in the complete experiment. The number of the selection area is constant hat is in one foot here.

Controls: There is no such control present in this experiment However, the density of pressure-sensitive nerve endings can be considered as control.

Hypothesis: the pressure-sensitive ending is significantly enriched in the feet of the elephant.

Sample size: subject in this study is only one elephant and one foot so the sample size is 1.

Presence of repeated measures: Repeated measures are not performed during this study is only one experiment of dissection is performed on a single subject.

How Clark Developed Seizures
The following list is not in the correct order. The first three events are numbered correctly. Drag and drop the
remaining events in the order that led to Clark's seizures.


picture above for the order.

Answers

Answer:

4. Low blood sodium concentration

5. Net movement of free water into the matrix

6. Increased matrix pressure

7. Abnormal neuron firing rate

8. Seizures

Explanation:

Seizures are defined as the common complication of drug intoxication.

As per the clinical observations for Clark , normal blood and matrix sodium concentration lose sodium ions due to diarrhea. As given too much water causes sodium levels to decrease. Due to lower sodium concentration, the free water move into the matrix and increased matrix pressure. This pressure causes the abnormal neuron firing rate to increase which causes seizures.

Hence, the correct order is:

4. Low blood sodium concentration

5. Net movement of free water into the matrix

6. Increased matrix pressure

7. Abnormal neuron firing rate

8. Seizures

Which of the following is true regarding enzymes?
A one enzyme can work with any substrate
B they can be used extracellularly
C they are made of only protein
D they are used entirely in the reaction

Answers

Answer:

C .they are made of only protein

Enzymes can be used extracellularly. Therefore option B is correct.

Enzymes are biological catalysts that facilitate chemical reactions in living organisms.

While enzymes are highly specific in their action, option A is incorrect because each enzyme typically works with a specific substrate or group of related substrates.

Option C is also incorrect because enzymes can be composed of both protein and non-protein components, such as cofactors or coenzymes.

Finally, option D is incorrect because enzymes are not used up entirely in the reaction but rather can be reused multiple times, making them efficient catalysts.

Therefore option B they can be used extracellularly is correct.

Which of the following is NOT true about matter in the biosphere?
a) Matter is transferred in one direction through the biosphere. b) Biogeochemical cycles transform and reuse molecules. c) The total amount of matter decreases over time. d) Human activity does not affect the movement of matter

Answers

Answer:

c) The total amount of matter decreases over time.

Explanation:

The statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

The biosphere refers to the total of all ecosystems of the Earth.

The biosphere can be defined as a closed system in terms of matter because matter does not enter or exit.

In the biosphere, the total amount of matter remains constant over time, whereas the total amount of energy decreases over time.

This energy is lost in the form of heat when it spreads from the Earth's surface and outward into space.

In conclusion, the statement 'the total amount of matter decreases over time' is NOT true about the matter in the biosphere (Option c).

Explanation:

Veteran trees are home to a variety of invertebrate species because a woodland's diversity is essential (insects, spiders, millipedes, centipedes, etc.), Thus, option B is correct.

What is the rise in biodiversity in woodland ecosystem?

In addition to lichens and fungi. Mature forests also favor bats among other species. Biodiversity in the woodland is a result of structural diversity.

Stability increases with biodiversity in ecosystems, species, and people. For instance, species with numerous populations that are adapted to a wide range of conditions and high genetic diversity are more likely to be able to withstand disturbances, disease, and climate change.

Generally speaking, expanding the variety of habitats or vegetation structures present at a site can be done to increase biodiversity.

Which function allows animals to find mates?
movement

Answers

Answer: MOVEMENT

Explanation:  

Movement

Movement can be described as the change in the place of an object or animals, without the ability to move there is not a possibility of life on earth. Movement is essential for many animals that help them to find food, shelter, and mate for the reproduction and produce offspring by mating.

The function that allows animals to find mates is movement, which is present in the first option as movement is a unique characteristic that is only present in animals but not in plants.

What is the significance of the movement?

In the animal kingdom, movement is required to find a mate, as the animal must move from one location to another to find a suitable mate, while it is absent in plants. Plants do not move, but pollinators assist in this process, whereas animals use movement to find food by walking on their legs or flying, and they also use movement to find mating partners.

Hence, the function that allows animals to find mates is movement, which is present in the first option as movement is a unique characteristic that is only present in animals but not in plants.
