Tom and Jerry start at the same location. Tom is travelling due east at a velocity of 5 m/hr. Jerry is travelling due northwest

at a velocity of 6 m/hr. After 1 hour, how fast is the distance between them changing

Answer:

The distance between them is changing at the speed of 10.16 m/hr

Explanation:

Consider the sketch attached below.

The question is simply asking to calculate the resultant of the two velocities.

To get the angle between them, we simply use the coordinates of the two vectors to determine the angle between them.  

90 + 45 = 135°

from the cosine rule we have

c^{2} = a^{2} + b^{2} - 2abcosθ

c^{2} = 6^{2} +5^{2} - 2 ×6×5×cos 135

c^{2} = 103.426

c = \sqrt{103.426}

c = 10.17 m/hr

Production of excessive amounts of acetyl coa molecules leads to the synthesis of ____.
Evgesh-ka [11]
Fatty acids

fatty acid synthesis is the formation of fatty acid from acetyl coa and NADPH with help of the enzyme known as fatty acid synthases. This reaction occurs inside the cytoplasm of the cell. The fatty acids that were formed were derived from carbohydrates via glycolytic pathway. This pathway can also give glycerol which is different form fatty acids

An ecosystem is a self supporting system in which there is a flow of materials and energy.

<h3>What is an ecosystem?</h3>

An ecosystem is a self supporting system in which there is a flow of materials and energy.

Let us now see the role of each organism in the small ecosystem.

  • flower - producer
  • butterfly - primary consumer
  • bird - secondary consumer
  • earthworm - decomposer

Drag the pink labels onto the pink targets to identify the two main phases of the cell cycle. Then drag the blue labels onto the
zavuch27 [327]

Answer:

There is no diagram provided so I will just explain the mitotic cell cycle.

Here’s a quick basic arrangement in chronological order interphase, mitosis, and finally cytokinesis.

So first you start with interphase which consist of three phases G1 phase, S phase, G2 phase. Cellular growth occurs in G1 phase of interphase this is followed by S phase which is simply when DNA replication occurs. Final this is followed by G2 phase or further growth in preparation for mitosis and/or meiosis.  

I am only going to explain mitosis but just so I don’t confuse you meiosis can also follow interphase. So mitosis consist of four phases. Prophase, metaphase, anaphase, and telophase.

Prophase: in this phase the nuclear membrane would dissipate and the chromosomes would condense.

Metaphase: then in metaphase the chromosomes would align in the center of the cell and spindle fibers or microtubules would began growth from the centrioles.  

Anaphase: by the start of this phase spindle fibers would have attached themselves to the chromosomes kinetochores. In this phase the chromatids would separate and that’s really it as you can tell this is the shortest phase in mitosis.

Telophase: finally the chromosomes would be brought to the polar opposite ends of the cell and the nuclear membrane would reform. Also the chromosomes condensed chromosomes would unravel eventually they would be invisible.

Finally the cell would enter cytokinesis were it would split at the cleavage furrow which would have started in anaphase of telophase, all a cleavage furrow is, is microfilaments “pinching the cell” which is just them pulling on either side of the center of the cell.

A scientist separates a population of lizards into two groups. what would most likely increase the rate of speciation in this po
eimsori [14]
<span>If the population is separated long enough, this means that random sampling in mating and reproduction, that occurred in the initial population has been restricted</span><span>. The two population will, therefore, adapt to their local environments and become reproductively isolated with time. After long periods of time, the two lizards population will have different alleles and will not be able to mate and produce viable offsprings hence will have speciated.</span>
