How does digitizing images make it easy to transmit images?

Answers

Answer:

Digitizing means converting something into digital form.

Digitizing image means converting any image into digital format and the image will be organized into bits or pixel. The bits or numbers are then processed by a computer and output is generated as visible-light image,

There are several advantages of digitizing images and one cam easily tansmit images:

A digitizing image is saved in pixel or square, when computer processes teh pixel or square it gives the image. More number of pixel means better quality of image.The digitized image can be easily send or share in compressed form which takes less space in computer and without affecting quality.Digitized images helps to easily transmit real image without any blur effect.

Hence, digitizing image is common now a days to transmit images of better quality in easy way.

B. The chlorophyll in the leaves break down, revealing yellow and red pigments that had been masked by the green pigments.
C. Xylem and phloem fill with ions and organic substances that prevent freezing.
D. Meristems form thick scales to protect next year's buds from cold winter temperatures,

Answers

Answer: Option A, C and D.

Explanation:

Cold temperature affects plants that cannot adapt to it and can eventually lead to their deaths.

If the temperature, and therefore the metabolism, remain low for an extended period, plant quality will suffer, and death may occur. A period of cold weather may also alter plant growth, as when certain vegetables “bolt,” or produce seed stalks, in response to several days at low temperatures

But maple plants in temperate region has develop some characteristics or adaptions that help its survive cold temperatures. Maple plants can tolerate frost and light freezes for short duration because they are cool plants and development characteristics to do so.

Auxins in them stimulate one final spurt before winter. Their xylems and phloems are filled with ions that prevent freezing.

They have a thick meristems which form thick scales to protect next year's buds from cold winter temperatures,

This was simulation. What are some variables that this peppered moths simulation does not address?

Answers

Answer:

The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.

You are evaluating the effect of different types of fertilizers on plant growth. You plant 12 tomato plants and divide them into three groups, where each group contains four plants. To the first group, you do not add fertilizer and the plants are watered with plain water. The second and third groups are watered with two different brands of fertilizer. After three weeks, you measure the growth of each plant in centimeters and calculate the average growth for each type of fertilizer. Identify the independent variable, dependent variable, control group, and experimental group from this experiment?

Answers

Answer:

Control group - the plant group which has not received the fertilizers treatment.

Experimental group- the groups treated with different varieties of fertilizers.

Independent variable- amount of water and fertilizers

Dependent variable- growth of plants

Explanation:

A scientific experiment is performed in a way that the experimental samples are classified into the control and experimental groups. Also, the experiment involves various variables to be studied which can be classified as an independent variable and dependent variable.

In the given question, the experimental samples are:

1. Control group- The samples which are not provided with the variable being studied like the experiment is performed to test the effect of fertilizers and "the plant group which has not received the fertilizers treatment" can be considered the control group.

2. Experimental group- the samples in which the variable to be studied are provided with that is "the groups treated with different varieties of fertilizers."

In the given question, the variables are:

1. Independent variable- the variable which can be changed or modified or can change on their own like "amount of water and fertilizers" in the experiment.

2. Dependent variable- the variable which is being tested, can be measured and is dependent on an independent variable like the " growth of plants" in the experiment.

Monotremes, marsupials, and placentals are the three animals that could match this phylogenetic tree.

Explanation:

Monotremes, marsupials, and placentals belong from a common ancestor. Those organisms which have one common ancestor are also called monophyletic. These animals have some changes which occurs with the passage of time but most of characters are similar to each other. In placentals animals placenta is present while in Monotremes and marsupials this placenta is absent.

A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.

What do you mean by Hardy-Weinberg equilibrium?

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.
