Compare the nervous system of the shrimp to that of a vertebrate.

Answers

Answer: The majority of animals on our planet, about 95 percent, do not possess a true backbone and are called invertebrates. It's common knowledge that vertebrates like humans have a complex nervous system that reacts to stimuli, but much less is known about invertebrates like shrimp and insects. While it's somewhat different from that of vertebrates, shrimp do have a central nervous system comprised of four main parts.

Explanation:

The nervous system is a highly specialized organ found in vertebrates.

The nervous system

The nervous system is a complicated system in the body of a vertebrate that is made up of the peripheral nervous system, which includes cranial nerves, spinal nerves, involuntary nerves, etc., and the central nervous system, which includes the brain and spinal cord.Neurons in the nervous system primarily relay signals to the various bodily parts.Somatic and visceral components are part of the peripheral nervous system.The two halves of the vertebrate nervous system are the grey matter and the white matter.The central nervous system and the peripheral nervous system make up the nervous system.The spinal cord and the brain, which regulate all bodily functions, make up the central nervous system.The cranial and spinal nerves, on the other hand, are part of the peripheral nervous system, which links the central nervous system to the rest of the body.Nerves carry electrical impulses from the skin and other sensory organs to the brain, which interprets the stimuli and delivers a reaction to the muscles and glands of the body.

How is the process of photosynthesis essential to sustaining life on Earth?​

Answers

Answer:

Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.

... The importance of photosynthesis in our life is the oxygen it produces.

Answer:

without the process of photosynthesis, plant would not be able to provide glucose (the food they consume) and in turn, they would die. Plants also produce )2 as a byproduct of photosynthesis which humans depend on so they we breathe.

Outline THREE adaptations of terrestrial plants for their survival in their habitat.

Answers

Answer:

Stomata for gas exchange, water resistant waxy cuticles on leaves and specialized cells for support.

Explanation:

Plants have undergone several modifications for life on land. These include the development of several mechanisms:

a waxy, thick water-repellent cuticle- the thick cuticle provides a barrier to water loss from plant tissues in the leaf. stomata- these moderate the evaporation of water, an important commodity to land dwelling terrestrial organisms. They also regulate gas change cells to provide strength and rigidity- plant cells are specialized cells that contain lignin and cellulose, these are rigid provide good support against gravitational forces, Without them the stem would break and the cells would readily lose water

Answers

Answer:

D. improve fertility

Explanation:

A garden supply company has an advertisement selling beneficial bacteria. They claim that the bacteria will help gardeners grow better gardens because of better soil.

This claim is simply based on the premise or fact that some bacterias can improve fertility of the soil.

Some species of bacterias are living microorganisms that are capable of decomposing organic matter into nitrogen, carbon and other nutrients, which are then released into the soil in a plant available form when in excess and this cycle continues with reproduction of new bacterias.

Some examples of these bacterias are Klebsiella, Anabaenopsis, Beijerinckia, Azotobacter, Clostridium, Anabaena, Nostoc, Bacillus etc.

Considering the connections between Yellowstone’s wolves, aspen and willow trees, and elk; which one is the keystone species.

Answers

Answer:

The keystone species is the wolf.

Explanation:

Every species of organism is important to the ecosystem, so if just one species gets extinct for whatever reason there will be consequences for the other species. How big the consequences will be, depends on the species and on how big of an effect it has on the ecosystem. Some species have relatively small importance, while some have huge importance, and the ones that have huge importance are called keystone species.

The keystone species have such big importance to an ecosystem that with their presence everything is under control, but if they go extinct then the ecosystem suffers badly and changes dramatically. In this case, a keystone species is the wolf. The wolves control the elk population, which in turn means that there is no shortage of food for the elk and they don't damage the young trees. By not damaging the young trees, they grow, so there is a much larger area covered by forest. More forest means less erosion, the water of the streams is better controlled, and there is less meandering. If the wolves are out of the picture, as they were for some time, the picture is totally opposite.

Two students are given cubic boxes, measuring 10 cm on a side. Robert puts a single glass marble with a
diameter of 10 cm in the box. Susan puts 1,000 1-cm glass marbles in her box.

1. Whose box has more empty space? Explain.

Answers

Answer:

Both boxes have the same amount of empty space

Explanation:

Given

Cube Box

[tex]Length = 10cm[/tex]

Robert:

1 glass marble

[tex]Diameter = 10cm[/tex]

Susan:

1000 glass marble

[tex]Diameter = 1cm[/tex]

Required

Whose box has more empty space?

First, we need to calculate the volume of the cubic box.

[tex]Volume = Length^3[/tex]

Substitute 10cm for Length

[tex]Volume = 10^3[/tex]

[tex]Volume = 1000cm^3[/tex]

Next, calculate the volume of Robert's glass

Volume is calculated as:

[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere

Where

r = radius

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]Diameter = 10cm[/tex] --- Given

Substitute 10 for diameter

[tex]r = \frac{1}{2} * 10cm[/tex]

[tex]r = 5cm[/tex]

So:

[tex]Volume = \frac{4}{3}\pi r^3[/tex]

[tex]Volume = \frac{4}{3} * \frac{22}{7} * 5^3[/tex]

[tex]Volume = \frac{4}{3} * \frac{22}{7} * 125[/tex]

[tex]Volume = 523.8cm^3[/tex]

Next, we determine the volume of Susan's 1000 glasses

Volume is calculated as:

[tex]Volume = \frac{4}{3}\pi r^3[/tex] ---- Volume of a sphere

Where

r = radius

[tex]r = \frac{1}{2} * Diameter[/tex]

[tex]Diameter = 1cm[/tex] --- Given

Substitute 1cm for diameter

[tex]r = \frac{1}{2} * 1cm[/tex]

[tex]r = 0.5cm[/tex]

Substitute 0.5cm for radius in [tex]Volume = \frac{4}{3}\pi r^3[/tex]

[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.5^3[/tex]

[tex]Volume = \frac{4}{3} * \frac{22}{7} * 0.125[/tex]

[tex]Volume = 0.5238[/tex]

But there are 1000 glasses.

So, the volume of 1000 glasses is:

[tex]Volume = 0.5238 * 1000[/tex]

[tex]Volume = 523.8cm^3[/tex]

--------------------------------------------------------------------------------------------------------------

For Robert:

[tex]Volume = 523.8cm^3[/tex]

For Susan:

[tex]Volume = 523.8cm^3[/tex]

Since, they have the same volume.

Both boxes have the same amount of empty space

From the dimensions of glass marble for robert and susan, we can say that; none of the given boxes have more empty space.

We are told that the cubic boxes have a measure of 10 cm for its' sides.

Formula for volume of a cube is;

V = lwh

where;

l is length

w is width

h is height

Thus; V = 10 × 10 × 10

V = 1000 cm³

For Robert;

We are told that he puts a glass marble with a diameter of 10 cm in the box. The glass is usually spherical in shape and the volume of a sphere is;

V = ⁴/₃πr³

Thus;

V_rob = ⁴/₃π × (10/2)³

V_rob = 523.6 cm³

Volume left for rob = 1000 - 523.6

Volume of empty space left for rob = 476.4 cm³

For Susan;

V = ⁴/₃πr³

Thus;

V_sus = ⁴/₃π × (1/2)³ × 1000

V_sus = 523.6 cm³

Volume left for susan = 1000 - 523.6

Volume of empty space left for susan = 476.4 cm³

find the kinetic energy of a ball of mass 200 grams moving at a speed of 20m/s​

Answers

We have a mass of 200g (0.2kg) moving at 20m/s

Kinetic Energy KE = ½ mv^2 where m is mass and v is velocity

Actually, v is a vector quantity, so KE = ½ mv•v

The dot product of 2 vectors a and b is abCosθ where θ is the angle between the vectors.

Obviously v•v = v^2 Cos0 = v^2

In this case, we have KE = ½ (0.2)(20^2) = 40kg-m^2/s^2 = 40J

So we have kinetic energy in the amount of 40 Joules.

Answer is 40J...............
