Answers

Answer:

The process by which green plants and some other organisms in the presence of sunlight to synthesize nutrients from carbon dioxide and water is called photosynthesis.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.

Answer:

[tex]\huge\mathfrak\pink{ur}\huge\fbox\green{answer}[/tex]

The hydrogen bond is one of the strongest intermolecular attractions,

A single hydrogen atom can participate in two hydrogen bonds, rather than one. This type of bonding is called "bifurcated" (split in two or "two-forked"). It can exist, for instance, in complex natural or synthetic organic molecules

Answer:

We usually get some questions about how many hydrogen bonds these compounds can create, we use it to differentiate between the boiling point of each one of them so it would be great if you could help me.

So what I know that H2O has 4 hydrogen bonds those are 2 from hydrogen atoms and 2 from other molecules that has 2 hydrogen atoms connected to the 2 lone pair of electron that the oxygen has.

In HF, It has 2 hydrogen bonds. The same explanation implies here. In NH3, 2 hydrogen bonds because N doesn't have the required amount of lone pairs to make more hydrogen bonds.

Answer:

C ) A sperm cell

Explanation:

These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes of the parent cell – they are haploid. Meiosis produces our sex cells

Using calculations of the numbers of chromosomes in the egg and the sperm, calculate the number of chromosomes that will be present in the mule formed by their fusion

Answers

Answer: extra currents in the ground will disrupt power grid operations and  high-frequency radio waves used for radio communications will be blocked

Explanation:

In the case of a severe geomagnetic storm, extra currents on the ground will disrupt power grid operations and signals from radio navigation systems will be disrupted and be inaccurate.

A geomagnetic storm is caused by a CME (coronal mass ejection) from the sun that smacks against the earth's magnetic field and causes issues such as

Power grid failuresRadio signal disruptionsDamage to critical electronics

Etc.

Extra currents in the ground caused by the geomagnetic storm will disrupt power grid operations. We can also expect a disruption of all radio signals and communications due to changes in the ionosphere during the storm.

Satellites in the Earth's orbit would likely sustain critical damage and may be rendered inoperable, however, since satellites do not use technology to stay in orbit (this is done by the earth's own gravity) they will not fall to the surface, which is why this option is wrong. The final option is also wrong because high-frequency radio waves used for radio communications will be disrupted and unreliable but not blocked.

That is why In the case of a severe geomagnetic storm, power grid operations and signals from radio navigation systems will be disrupted and be inaccurate.

Explanation:

Answer:

For the complete encyclopedic entry with media resources, visit: http://www.nationalgeographic.org/encyclopedia/weathering/

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.

For example, certain kinds of air pollution increase the rate of weathering. Burning coal, natural gas, and petroleum releases chemicals such as nitrogen oxide and sulfur dioxide into the atmosphere. When these chemicals combine with sunlight and moisture, they change into acids. They then fall back to Earth as acid rain.

Lloyd’s lab partner is looking down into a test tube while he heats the contents by using a flame. Which action should Lloyd recommend to his partner if heating must continue?
Wear safety goggles while looking into the opening of the test tube.
Cover the opening of the test tube so that no materials can boil out of it.
Move the test tube so that the opening is pointing away from all students.
Put the test tube in a hot water bath so that no water can enter its opening.

Answers

The correct action that Lloyd should recommend to his partner who was looking down into the test tube if heating must continue would be to move the test tube so that the opening is pointing away from all students.

Wearing safety goggles (and looking directly down at the test tube) might not be enough to protect Lloyd's partner nor other students in case the content of the test tube splashes out.Covering the test tube might hinder any generated gas as a result of heating from escaping safely into the air and this might cause an explosion.Putting the test tube in a hot water bath so that water can enter its opening will definitely affect the reaction and prevent them from getting accurate results/observations.

Hence, the most correct action would be for Lloyd's partner to move the test tube so that the opening is pointing away from all students.

What is her balance now, that she owes her mom? excerpt from Of Plymouth Plantation by William BradfordAn Understanding with the Indians (1621)All this while the Indians came skulking about them, and would sometimes show themselves aloof off, but when any approached near them, they would run away. And once they stole away their tools where they had been at work and were gone to dinner. But about the 16th of March, a certain Indian came boldly amongst them and spoke to them in broken English, which they could well understand but marveled at it. At length they understood by discourse with him, that he was not of these parts, but belonged to the eastern parts where some English ships came to fish, with whom he was acquainted and could name sundry of them by their names, amongst whom he had got his language. He became profitable to them in acquainting them with many things concerning the state of the country in the east parts where he lived, which was afterwards profitable unto them; as also of the people here, of their names, number and strength, of their situation and distance from this place, and who was chief amongst them. His name was Samoset. He told them also of another Indian whose name was Squanto, a native of this place, who had been in England and could speak better English than himself.Being after some time of entertainment and gifts dismissed, a while after he came again, and five more with him, and they brought again all the tools that were stolen away before, and made way for the coming of their great Sachem, called Massasoit. Who, about four or five days after, came with the chief of his friends and other attendance, with the aforesaid Squanto. With whom, after friendly entertainment and some gifts given him, they made a peace with him (which hath now continued this 24 years) in these terms:That neither he nor any of his should injure or do hurt to any of their people.That if any of his did hurt to any of theirs, he should send the offender, that they might punish him.That if anything were taken away from any of theirs, he should cause it to be restored; and they should do the like to his.If any did unjustly war against him, they would aid him; if any did war against them, he should aid them.He should send to his neighbors confederates to certify them of this, that they might not wrong them, but might be likewise comprised in the conditions of peace.That when their men came to them, they should leave their bows and arrows behind them. After these things he returned to his place called Sowams, some 40 miles from this place, but Squanto continued with them and was their interpreter and was a special instrument sent of God for their good beyond their expectation. He directed them how to set their corn, where to take fish, and to procure other commodities, and was also their pilot to bring them to unknown places for their profit, and never left them till he died. He was a native of this place, and scarce any left alive besides himself. He was carried away with divers others by one Hunt, a master of a ship, who thought to sell them for slaves in Spain; but he got away for England and was entertained by a merchant in London, and employed to Newfoundland and other parts, and lastly brought hither into these parts by one Mr. Dermer, a gentleman employed by Sir Ferdinando Gorges and others for discovery and other designs in these parts.Readers can infer that Samosets visit to the community improves the relationship between the colony members and the Native Americans.Which detail from the passage best supports this inference? 1. He was a native of this place, and scarce any left alive besides himself.2. After these things he returned to his place called Sowams, some 40 miles from this place, but Squanto continued with them and was their interpreter3.
