And three animals that could match this phylogenetic tree.
Answer:
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.

Which of the following occur in a maple tree growing in a temperate climate in response to increasing cold weather? Choose three correct
answers.
A. Auxin production stimulate one final growth spurt before winter arrives,
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,
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,

How can you decrease the effort force needed to push a weight to the top of the ramp? A) cover the surface with carpet B) increase the length of the ramp C) increase the height of the ramp D) decrease the length of the ramp
Answer:
B) increase the length of the ramp
Explanation:
Less force is needed to move the object over a longer distance.
Answer:
You can decrease the effort force needed to push a weight up the ramp if you increase the length of the ramp. You could also decrease the height of the ramp.Lengthen the ramp, decrease the mass of the object, use a machine can you decrease the effort force needed to push a weight
Explanation:
A ramp is an example of an inclined plane. Think back to the example of the ramp and the moving truck. The ramp reduced the amount of force needed to lift the box by moving it over a greater distance. The longer an inclined plane, the less force is required to move an object upward.

How does digitizing images make it easy to transmit images?
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.

Which of these is true of fetal development by the end of the third trimester?
A. The placenta is absorbed by the uterus.
B. The fetus can survive outside the uterus.
c. All development is complete.
D. All growth is complete.
Answer:
B. The fetus can survive outside the uterus.
Explanation:
The third trimester starts in the wekk 28 (month 7 ) of fetal development and lasts until the birth pf baby, that is around week 40 (month 9) of pregnancy.
There are several changes occur in the thrid trimester of the fetal development such as hearing and visual has developed and the internal organs including the heart, lungs, intestines and stomach has developed enough.
So, at the end of fetal development of the third trimester as all the body organs have grown and developed, a fetus can survive outside the uterus.
The correct option is B.
Answer:
Option B
Explanation:
During the third trimester, the fetus continues to grow in weight and size however the body systems finish maturing. In fact, both mother’s body and the fetus continue to grow and change. Lungs, brain and kidneys keep maturing. Fetus position itself head-down and is 6 to 9 pounds in weight. Skull bones are soft but fetus become able to suck its thumb and cry. By 38 to 40 weeks, the lungs have matured fully . The end of third trimester marks the period when the fetus is ready for delivery. Hence option B is the correct answer

the answer is A.Explanation:
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?
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.

Answer:
c
a

Explanation:
Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.
In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.
What is soil erosion?The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.
Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.
Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.
In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
