Cell division is the division of cells through a series of events. It results in reproduction, growth and repair. Nutrition is not a result of cell division.
What is a cell cycle?Cell cycle is a series of event where a cell grow, differentiate, accumulate nutrients, duplicates its genome and divide to form daughter cells.
Cell cycle has two phases in which one is interphase in which the cell grow and accumulate nutrition, along with this cell duplicates its genome. Second phase is M-phase in which cell division takes place.
Cell division helps cell in reproduction, growth and repair.
Thus, the correct option is b, as nutrition as it is not a result of cell division.

Write a paragraph explaining the steps involved in a muscle contraction starting from the brain sending a signal to the muscle and ending with the muscle contraction.
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.

Clematis C. Delphinium D. Ranunculus
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.
Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.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***

A scientist is studying three different plant species that appear to be closely related. All three are found in a wide variety of environments and are very similar in appearance. Which of the following would provide the best evidence regarding the evolutionary relationship of these three species?
Comparing the different climates in which the species can be found
Comparing the genomes of each species to see which are most similar
Determining whether the plants are capable of both sexual and asexual reproduction
Determining which types of animals eat each species
Determining the genomes of each species to see which is similar will provide the best evidence regarding the evolutionary relationship of these species. So the correct option is B.
What are evolutionary relationships?The relationships of different species with each other based on their history of evolution are called evolutionary relationships.
The study of the relationships between organisms by categorizing them into various kinds of groups is called systematics.
All the species of organisms, from bacteria to mammals have evolved from some kind of ancestral species by the process of evolution.
Determination of these evolutionary relationships is the key to understanding the process of evolution. Evolutionary relationships are determined by using evolutionary trees which are diagrammatic representations of ancestral species and their descendants.
The study of genomics to identify the similarity between organisms is yet another useful tool to determine the relationship between them.
Therefore the correct option is B.

Which description explains why there are two high and two low tides in a day? (4 points)
Earth moves closer to the sun and moon twice a day.
Earth revolves around the tidal bulges created by gravitational forces.
Earth rotates in and out of a tidal bulge twice a day.
The moon's gravity increases over the oceans and decreases over the land.
Answer:
Earth rotates in and out of a tidal bulge twice a day.
Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.
The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

Which molecule regulates how the organism looks and acts?
Answer:
In a cell, proteins can act as enzymes, structural features, pigments, and a host of other functions, including regulating the expression of other genes. This expression of genes leads to how an organism looks – its phenotype.
Explanation:
Gene regulation creates different types of proteins which make the structure of cell and organism looks, so the gene is responsible for looks and acts.
What is gene regulation?Gene regulation is a critical component of proper development. During development, genes are switched on and off in diverse patterns to make a brain cell appear and perform differently from a liver cell or a muscle cell, for example.
Gene control also enables cells to respond swiftly to environmental changes. Genetic differences can result from gene variants (also known as mutations) or through a natural process.
Genetic information is reorganized when a cell prepares to divide (known as genetic recombination). Different features in an organism can be introduced via genetic differences that modify gene activity or protein function.
Therefore gene is responsible for how an organism looks and act, it creates different proteins to make a cell.

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.
What is quadratic equation?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.
