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.

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...............

can somebody help me make a claim , evidence and reasoning on “Do you think school days should be made longer?

i need it now please help me

Answers

Answer:

i don't think so school days must be shorter and practical session must be longer theory is boring

Answer:

I think school days should not be made longer as this would impact the students mental health. Students attend school for approximately 7 hours a day in which they learn new content, this time being increased would cause stress and burden on students as classes would be longer and time spent at home would be less. Students need enough time to rest and relax their minds, as well as, spend time with their families. If extending school hours, students will have less time for self-care and family time which can lead to depression and loneliness. However, there are benefits of extending school hours such as more time to finish homework. But, a student's health must come first. In conclusions, school days should not be made longer.

Consciousness can best be described as __(blank)__.
a) Internal chemical systems that are regulated by a circadian rhythm
b) an ability to sleep and have lucid dreams
c) a lack of awareness of things going on inside or outside of yourself
d) an awareness of things going on inside or outside of yourself

Answers

d) cause consciousness is when you’re awake and aware

Consciousness can best be described as an awareness of things going on inside or outside of yourself, hence option D is correct.

How consciousness is regulated?

Wakefulness/arousal and awareness are frequently used as the two components that make up consciousness.

It appears that proper arousal levels and subsequently wakefulness, which is required for consciousness, depend on well-synchronized phases of awake and sleep.

Circadian rhythms are changes in the body, brain, and behavior that occur on a 24-hour cycle. Most living things, including animals, plants, and bacteria, are impacted by these natural processes, which predominantly react to light and darkness.

Therefore, the 24-hour cycle of normal physical, emotional, and behavioral changes that the body experiences.

when placed in a glucose solution, yeast cells will produce bubbles. which process are the yeast cells carrying out? A. chemosynthesis B. respiration C. photosynthesis D. transpiration​

Answers

Answer:

B. respiration

Explanation:

There's a Quizlet called "Biology 1st 9 weeks review" (it's created by Rodgerst4) that helped me!

The bubbles produced when yeast cells are placed in a glucose solution is because the yeast cells are carrying out respiration. The correction option would be B.

Yeast cells are able to carry out a type of respiration known as anaerobic respiration when placed in a suitable substrate medium like glucose. During this process energy in the form of ATP is generated in the absence of oxygen for the metabolism of the yeast cells. The equation of the reaction is as follows:

[tex]C_6H_1_2O_6 --->2 C_2H_5OH + 2 CO_2[/tex]

Thus, the carbon dioxide gas is released as bubbles in the solution as a result of respiration.

Koalas evolved after trout.

Explanation:

A cladogram is the diagrammatical representation of the relationship between the organisms. From the cladogram, it can be said that Koalas evolved after trout. Thus, option D is correct.

What is a cladogram?

A cladogram is used to show the relation between the different species through branching. It tells about the sequence in which the characteristics were derived.

From the cladogram, it can be seen that trouts developed the jaws, and amoeba are unicellular organisms. However, Trouts and Koalas do not share the same class but Koalas evolved after trout in the geological timeline of evolution.

Therefore, the Koalas evolved after trout.

She buys 5 ferns of the same species, which are all approximately the same age and height. She places one in white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.

The answer is D

Explanation:

In an experiment, the INDEPENDENT VARIABLE is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.

In this case, Suzie Q wants to know the effect of different colors of light on the growth of plants. She conducts this experiment using different colors of light namely: white light, green light, blue light, red light etc. This shows that the variable being changed/manipulated is the different colors of light.
