Mount Everest is the world's highest mountain. It is 29,028 feet (9km) above sea level. It is located in the Himalayas between Nepal and China. But now that we have sonar, we know about Mauna Kea. Mauna Kea is on Hawaii Island. It is 13,448 feet (4km) above sea level. From its base on the ocean floor, it is 33,796 feet (10km)! Should we still consider Mount Everest to be the highest mountain? Why or why not?

Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

When an offspring receives one green allele (G) and one red allele (R), the result id a green leaf with red veins
Answers
Answer:
GR
Explanation:
the genotypes of the parents are homozygous dominant GG and RR so when they fertilise they give all GR offsprings
The genotype of the plant is GR. This is because the offspring received green allele (G) as well as red allele (R), and both results showed up as the plant is green with red veins.
When something gives up alleles to its offspring, the parents originally have alleles like Aa and Bb. When offspring is created, you can use the Punnett square to guess which alleles will be passed on. In the plant’s case, G and R were passed on.

What type of response occurs when you watch someone eating a lemon and your face puckers?
external response
sour response
internal response
lemon response
Answers
Answer:
The type of response that occurs when you watch someone eating a lemon and your face puckers is an external response. An external response is a physical reaction that is visible to others and occurs in response to a stimulus, in this case, the sight of someone eating a lemon. It is also sometimes called a behavioral response.
An internal response, on the other hand, is a response that occurs inside the body and is not visible to others. For example, when you eat a lemon, you may experience an internal response such as an increased production of saliva in your mouth or a sour taste in your mouth.
A sour response is a type of internal response that refers specifically to the taste of something that is sour, such as a lemon.
A lemon response is not a commonly used term in psychology or physiology. It could refer to any type of response that is related to lemons, such as the external response of puckering your face or the internal response of experiencing a sour taste.

However, it's important to note that storm names are not necessarily assigned in order and can sometimes be skipped or reused in future years.
Answer:
Satellites, Radars, Storm Spotters
Explanation:
Satellites: Satellites take pictures of Earth at regular intervals from space, telling us where clouds are located. Meteorologists watch these pictures over time to watch for rapidly growing clouds, a clue to a possible thunderstorm. Satellites also can tell us the temperature of the cloudsRadars: Radars send out electromagnetic waves that can be reflected back by precipitation or other objects in the air. Radars can measure the intensity, size, shape, and movement of rain, hail, or debris in a storm. Radars can also show the wind speed and direction near and inside the storm, which can indicate rotation or shear.Storm spotters: Storm spotters are trained volunteers who observe and report severe weather conditions from the ground. Storm spotters can provide valuable information about the location, structure, and behavior of a storm that may not be visible on radar or satellite. Storm spotters can also confirm if a tornado is on the ground or if there is any damageMeteorologists use these tools and techniques to distinguish one storm from another based on their location, size, shape, intensity, movement, and features. They can also compare different sources of information to verify or correct their analysis of a storm.

Answer: Encourage students to set up a germination experiment by placing the seeds in different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to pot the same seed in more than one pot.
Explanation:
This option provides a clear and practical approach to the seed germination investigation. By setting up different conditions for the seeds, such as light vs. dark or wet vs. dry, the students can observe and compare how these conditions affect the germination process. Additionally, potting the same seed in multiple pots allows for a controlled comparison within the experiment.
By manipulating these variables, the students can gather valuable data and observations regarding the influence of light and moisture on seed germination. This approach promotes a hands-on and investigative learning experience, encouraging students to actively engage with the scientific process while documenting the changes that occur over time, such as the emergence of roots and shoots.
