grade 5 science MYA answers 1-10 =
Mr. Powell is demonstrating the water cycle. He shapes mountains out of clay on one end of a glass aquarium to represent land. He then pours some water into the aquarium and places a glass lid on it. Next, he turns on a lamp above the aquarium and, finally, he places a container filled with ice on the glass lid. In this model, which choice correctly identifies evidence of condensation?
a - water droplets falling on the clay
b - less water in the bottom of the aquarium
c - water running from the clay into the water
d - water forming on the lid under the container
PLEASE HELP!!!!!! this is due in 5 mins and this is my only question left o_o
Answer: d - water forming on the lid under the container
Explanation:
Condensation is the process that describes the change of state of water from gas to liquid. It happens in the water cycle when water vapor gets to the atmosphere and due to the lower temperatures turns into liquid water that then forms clouds.
In the demonstration, the container is meant to be the clouds so when water forms under the container, that is condensation happening because the water vapor has not turned back to liquid after leaving the aquarium water as water vapor.

The innate (non-specific immunity) immune system Select one:
A. is based on phagocytes and antimicrobials contained therein
B. kills bacteria according to the same principle as immunoglobulins
C. requires recognition of a surface epitope by immunoglobulins
D. None
Answer: A. is based on phagocytes and antimicrobials contained therein
Explanation:
The innate immune system a person has is the one that they were born with to help them counter all foreign organisms as it views them as threats to the immune system.
It is based on phagocytes as well as natural antimicrobials that will immediately go into action once foreign organisms are detected in the body to eliminate any threats these organisms might pose.

(WILL GIVE BRAINLIEST ONLY IF CORRECT!!) How is the dispersive model different from the semiconservative model of DNA replication?
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.
Answer:
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
Explanation: it helps to remember that dispersive means to disperse your DNA molecules! And semi conservative means you keep one of your old strands! Hope this helps!
Answer:
option 1 is correct
Explanation:
in dispersive, each strand of DNA has alternating fragments of old and new DNA while in the semiconservative each new double helix consists of one old and one new strand.

Explanation:
Look at the following diagram of the carbon cycle.An image of carbon cycle is shown. The sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. An arrow is shown from the sun towards the left tree marked A. The sun is marked B. There is an arrow from the air above the clouds, marked C, towards the left tree. An arrow from a location close to the ground marked D points towards Dead Organisms, which is a label under the animal. An arrow marked E points from the right tree straight up to the clouds. An arrow marked F points from the animal straight up to the clouds. An arrow marked G points from the factory towards the air above the clouds, C. There is an arrow pointing from the air to the lake labeled Carbonates in Water, an arrow pointing down from dead organisms to Fossils and Fossil Fuels, and an arrow from Fossils to the factory.Which of the following facts is best represented by the arrow pointing from G to C? The chemical energy present in fossil fuels is used to create new forms of energy used for photosynthesis. Energy is conserved because the chemical energy present in fossil fuels is used up completely during burning. The mechanical energy produced on burning fossil fuels is transformed into chemical energy stored in carbon dioxide. Energy is conserved because the mechanical energy produced on burning fossil fuels is less than the chemical energy formed.

When reading “This tree starts with our ancient ancestors and leads to many species of hominids that are now extinct, with humans at the tip of the only surviving branch,” what did that make you think about humans? Do you think this indicates that humans are the pinnacle of evolution? Are they? Explain.
Answer:
Yes, humans are the pinnacle of evolution.
Explanation:
Adaptability to the change environment by the human is the only reason for the survival of human beings as compared to other hominids. The human survival also occurs due to evolution that changes the physical structure of humans and they are able to survive in that environment condition in which no other hominids survives so we can say that humans are the pinnacle of evolution.

Answer:
Nondisjunction (during meiosis in gametogenesis)
Explanation:
This is meiosis because we can see germ cells present, and the chromosome number is halved (typically) by the end of the process. This is nondisjunction because the sister chromatids/chromosomes are failing to separate properly during cytokinesis, causing improper amount of chromosomes in the germ cells. So on the left you have nondisjunction during meiosis II, because you have two cells with the proper amount of chromosomes after the first division. And on the right you have nondisjunction during meiosis I, because you have one cell with no chromosomes after the first division. The steps are as follows: 1 - Meiosis, 2 - Meiosis II, 3 - Fertilization, and 4 - Zygote (creation of).
Which is larger, 40 centimeters or 670 millimeters?
Answer:
670 Millimeters
Explanation:
1 Millimeter = 0.1 Centimeter
670 millimetres is equal to 67 cm which is greater than 40 cm. So 670 mm is greater than 40 cm.
What is a millimetre?It is a unit of measurement for length/distance. It is a very small unit of measurement. It is a visible unit of measurement, unlike a micrometre which is smaller than a millimetre but measures things that are not visible to the unaided eye.
It is a part of the metric system commonly used in Science, Technology Engineering and Mathematics (STEM). A millimetre is measured as one-thousandth of a metre.
The word metre is derived from a Greek word which means measure. The metric system that is used internationally for the measurement of various quantities is based on decimals.
Like a millimetre is one-thousandth of a metre, a micrometre is one-millionth of a metre. A centimetre is one-hundredth of a meter and a quantity smaller than a micrometre called a nanometer is one-billionth of a meter.
Therefore, 670 mm is 67 cm which is greater than 40 cm.

In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true-breeding. If plants with blue flowers are crossed to red-flowered plants, all F1 plants have yellow flowers. When these produced an F2 generation, the following ratio was observed: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve. Determine the F1 results of a cross between true-breeding red and true-breeding mauve flowered plants.
Answer:
F1) 100% bbRr, red flowered plants.
Explanation:
Available data:
flowers may be yellow, blue, red, or mauvecolors may be true-breedingthe cross of blue-flowered plants with red-flowered plants, produce plants that have yellow flowersF2 generation: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve.Knowing that the phenotypic ratio is 9:3:3:1, we can assume that there are two genes involved in the flower color expression. We can name these genes B and R with a dominant and a recessive allele each (B, b and R, r respectively).
According to the first cross, we might establish the following genotypes:
1st Cross: blue-flowered plant x red-flowered plant
Parentals) BBrr x bbRR
Gametes) Br, Br, Br, Br bR, bR, bR, bR
F1) 100% BbRr, yellow plants
Parentals) BbRr x BbRr
Gametes) BR, Br, bR, br
BR, Br, bR, br
Punnett square) BR Br bR br
BR BBRR BBRr BbRR BbRr
Br BBRr BBrr BbRr Bbrr
bR BbRR BbRr bbRR bbRr
br BbRr Bbrr bbRr bbrr
F2) 9/16 yellow ---> 1/16 BBRR + 2/16 BBRr + 4/16 BbRr + 2/16 BbRR
3/16 blue ------> 1/16 BBrr + 2/16 Bbrr
3/16 red---------> 1/16 bbRR + 2/16 bbRr
1/16 mauve ----> 1/16 bbrr
So,
Yellow-flowered plants: BBRR, BBRr, BbRR, BbRrRed-flowered plants: bbRR, bbRrBlue-flowered plants: BBrr, BbrrMauve-flowered plants: bbrrAccording to these genotypes, the second cross would be like following,
2nd Cross: true-breeding red-flowered plants with true-breeding mauve flowered plants.
Parentals) bbRR x bbrr
Phenotype) Red Mauve
Gametes) bR, bR, bR, bR br, br, br, br
Punnett square) bR bR bR bR
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
br bbRr bbRr bbRr bbRr
F1) 100% bbRr, red flowered plants.
