Which of the following illustrates the principle of induction in invertebrates?

A. In an embryo, the presence of a notochord beneath the ectoderm results in the formation of a neural tube.
B. A neuron synapses with another neuron via a neurotransmitter.
C. Eye muscles constrict in response to light.
D. Secretion of TSH stimulates the secretion of thyroxine.
E. The maternal parent induces spontaneous expression of recessive genes.

Answers

Answer 1

Answer:

A

Explanation:

A

How does the ectoderm that will make up the future eye know to develop into an eye? The cells are "told" to develop into an eye because the nearby retina releases chemical signals that direct the development of the cells. This process is called induction. Choice A depicts a similar situation. The notocord releases chemical signals that tell the overlying ectoderm that it is time for it to become the neural tube. None of the other choices depict the process of induction.

Adjustment, accommodations, modifications, and revision are all synonyms for which word?

Answers

Answer:

Change.

Explanation:

All of the words we see here are another word for change, as they all have to do with something being changed.

Here's the words in a sentence:

Original wording: "Yes, I would like you to make a change in your schedule for us please."

Now let's implement the other words into this sentence, and see if they still mean the same thing.

"Yes, I would like you to make an adjustment in your schedule for us please."

"Yes, I would like you to make some accommodations in your schedule for us please."

"Yes, I would like you to make a few modifications in your schedule for us please."

"Yes, I would like you to make a revision in your schedule for us please."

With all of these sentences, we get the same meaning, since they are synonyms,

Why are streak plates used the test minerals?

A. They show you the silicon content of the minerals
B. They show you the colors of the impurities in the mineral
C. They show you the true color of the minerals

Answers

Answer: c

Explanation: correct answer

Streak plates are used to test minerals because they show you the color of the mineral in powdered form. So, the correct option is C.

What are Streak plates?

Small pieces of unglazed glass or porcelain are known as streak plates, and they are used in mineralogy to assess the streak color of a mineral. They are usually a few inches in length and about an inch in width.

The streak of a mineral is its color after it has been ground into a fine powder and rubbed across a streak plate. Because some minerals have recognizable colors that differ from their actual color, it can be helpful to identify them.For example, hematite is a dark brown mineral with bright red streaks. You can differentiate hematite from other dark brown minerals by looking at the color of the streaks.

Therefore, the correct option is C.

Answers

Answer:

C. glucose, energy

Explanation:

Glucose is ‘raw material’ in cellular respiration. It passes through the glycolysis cycle, in the cytoplasm of the cell. This occurs in virtually all cells. In eukaryotic cells, with mitochondria, the product of glycolysis (usually pyruvate) is channeled to the organelle and pass through the Citric acid /Krebs cycle that produces even more ATPs than glycolysis.

Explanation.
Where the white lines intersect in the middle are surrounded by more white on all sides than any other point along the white line segments. Your retinal ganglion cells notice that there is more white around where they meet because they are organized to increase contrast with lateral inhibition. Better contrast makes it easier on our eyes to see the edge of something. Your retinal ganglion cells don’t respond as much at the intersections because there is more lateral inhibition for more white spots nearby, compared to the lines which are surrounded with black.

Simpler explanation:
White lines cross across a black background. Where the lines cross, there is a higher contrast. Your retinal ganglion cells notice that there is more white around where they meet, making them not respond as much at the intersections. There is more lateral inhibition, where neurons response to stimulus is restrained by the activity of nearby excited neurons, for more white spots nearby.

An individual invested $5,000 into two accounts. They placed part of it into an account that earned 4.5% and the rest in an account that earned 6%. The total annual income generated from this investment in simple interest was $270. How much was invested in each account?

Answers

Based on the total annual income from simple interest, $2000 was invested in Account 1 while $3000 was invested in Account 2.

What is simple interest?

Simple interest the amount of interest charged on a sum at a given rate and for a given period of time.

Simple interest = Principal × rate × time

In simple interest, the principal amount is always the same.

Given that the principal is $5000

This amount was invested into two account at the following rates:

Account 1 at 4.5% interest rate

Account 2 at 6% interest rate

Total income from simple interest = $250

Let amount invested in Account 1 be y; amount invested in Account 2 will be 5000 - y

Interest on Account 1 = y × 4.5% × 1 = 0.045y

Interest on Account 2 = (5000 - y) × 6% × 1 = 300 - 0

06y

0.045 y - 0.06y + 300 = 270

-0.015 y = -30

y = 2000

5000 - y = 3000

Therefore, $2000 was invested in Account 1 while $3000 was invested in Account 2.
