The rocket will then be at least 19.5 m above the ground for the interval 0.75≤t≤3.25  

0.75≤t≤3.25

The time interval for which the rocket is more than 3200 km above the ground level is 61.25 seconds.

To solve this problem, we need to find the time interval for which the rocket's distance above the ground level is greater than 3200 km.

We can start by setting the equation for the rocket's distance above the ground level equal to 3200:

We can then solve this equation for t using the quadratic formula

[tex]480t - 16t^2 = 3200\\t = (-480 +/- sqrt(480^2 - 4*(-16)*3200)) / (-32)\\This simplifies to:\\t = (-480 +/- sqrt(480^2 + 256000)) /\\ (-32)t = (-480 +/- sqrt(2304000)) /\\ (-32)t = (-480 +/- 1500) / (-32)t = (-1980) /\\(-32)t = 61.25t = -24.25\pi[/tex]

Since the time interval we are looking for is positive, we can ignore the negative solution. The time interval for which the rocket is more than 3200 km above the ground level is therefore 61.25 seconds.

Answer:

A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles.Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. The neuromuscular junction is the name of the place where the motor neuron reaches a muscle cell. Skeletal muscle tissue is composed of cells called muscle fibers. When the nervous system signal reaches the neuromuscular junction a chemical message is released by the motor neuron. The chemical message, a neurotransmitter called acetylcholine, binds to receptors on the outside of the muscle fiber. That starts a chemical reaction within the muscle.Acetylcholine Is Released and Binds to Receptors on the Muscle Membrane.

A multistep molecular process within the muscle fiber begins when acetylcholine binds to receptors on the muscle fiber membrane. The proteins inside muscle fibers are organized into long chains that can interact with each other, reorganizing to shorten and relax. When acetylcholine reaches receptors on the membranes of muscle fibers, membrane channels open and the process that contracts a relaxed muscle fibers begins:

Open channels allow an influx of sodium ions into the cytoplasm of the muscle fiber.

The sodium influx also sends a message within the muscle fiber to trigger the release of stored calcium ions.

The calcium ions diffuse into the muscle fiber.

The relationship between the chains of proteins within the muscle cells changes, leading to the contraction.

2. Four reasons why knowing the entry requirement is important include;

a. It helps the students chose the right courses in high school.

b. It provides a standard for the universities to evaluate students objectively.

c. It ensures the admittance of students to courses suited for their capabilities and strengths.

d. It prepares students for the tasking academic environment by ensuring that they have a background knowledge of their chosen course.

Explanation:

Before students can be granted admission into schools chosen by them, they must meet certain standards to be deemed qualified by the admitting institution. Knowing these standards on time gives the students a sense of purpose and helps them to develop skills and abilities that make them qualified for admission into these schools.

It also helps the university choose the right students for different courses. Studying ahead to have the required certificates for admission helps the student gain background knowledge of their future course.

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

Explanation:

ΔG°' for Citrate is +6.64 kJmol-1

ΔG°' for Isocitrate is -267 kJmol-1

ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant

ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

Answer: They are called Moraines

Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.

Glaciers constantly move on land and they do this under their own weight.

As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.

The resulting hill formed as a result of this soil movement is called a Moraine.

A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.

Answer:

1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:

-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.

-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.

-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.  

-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.

2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.  

Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail  

This is us, we have thumbs, and vertebrates.

3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera

Question:

Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.

Dichotomous Key of Ranunculaceae

#1.

a. Fruit is a group of alkenes.............................. go to step 2

b. Fruit is a group of follicles..............................go to step 4

#2.

a. Petals are not present.....................................go to step 3

b. Petals are present............................................Ranunculus

#3.

a. The flower has 4 sepals.................................. Clematis

b. The flower has 5 sepals................................... Anemone

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium

The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus

Answer:

The species belongs to Delphinium genera.

Explanation:

A dichotomous key is relatively simple to interpret. All you need to do is to:

- carefully observe your organism,

- know some technical terms or have a biological dictionary, and

- follow the descriptions.

The dichotomous key is going to lead you to the answer.

In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.

So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.

#1.

a. Fruit is a group of alkenes.............................. go to step 2.

b. Fruit is a group of follicles..............................go to step 4.

We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium  

We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***
