Prompt Option 1: Choose an organism. Using at least 5 sentences, describe why your specific organism could have siblings that share the same parents, but might have different traits. Why might they be different? Give specific examples of traits that might be different.
Answers
The domestic dog, Canis lupus familiaris, is an example of an organism that might have siblings with dissimilar features.
What is the organism?Dogs are a very diverse species, with a wide range of physical and behavioral characteristics. Because they have the same parents, siblings have genetic makeup that is similar, but different gene combinations can result in significant variances in characteristics like coat color, size, and temperament.
The puppies' coats might be any color between black, white, and gray if one parent has a white coat and the other has a black coat, for example. Additionally, environmental factors and genetic abnormalities might cause attribute discrepancies between siblings.

Answer:
One possible organism that I can choose is a dog. A dog is an animal that belongs to the kingdom Animalia, the phylum Chordata, and the class Mammalia.
A dog could have siblings that share the same parents, but might have different traits because of genetic variation.
Genetic variation is the difference in DNA sequences among individuals of the same species
It can result from mutations, recombination, or random assortment of chromosomes during meiosis
Some examples of traits that might be different among dog siblings are coat color, eye color, size, shape, and temperament
These traits are influenced by both genes and environment

Which statement describes what might happen to a large rock in a windy desert?
It doesn’t change because there is no water to wear it down.
It doesn’t change because it’s always hot.
It is reduced and shaped by sand in the wind that wears it down.
It grows larger as sand gets caught in its crevices.

Which sentence supports the fact that we always see the same side of the Moon?
The Moon takes about four weeks to rotate once on its axis and about the same time to orbit the Earth. The gravitational effect of Earth has slowed the rotational period of the Moon to match its orbit. Since the rotational period is exactly the same as the orbital period, the same portion of the Moon always faces Earth. As the Moon orbits Earth, the lit side that we see changes in size. These changes are called the lunar phases.

Where do wild hamsters like to sleep?
A. on the mountain peaks
B. out in the open
C. in the underground borrow
D.inside caves
Answers
Answer: Wild hamsters like to sleep in underground burrows.
Explanation:
Wild hamsters are found throughout Europe and Asia. The wild hamsters are nocturnal and have bad eyesight.
They navigate through their sense of smell and touch, also with their whiskers.
Wild hamsters like to live in warm and dry areas such as deserts.
They would like to sleep in underground burrows which are series of tunnels to live and to breed. Living underground makes the wild hamsters cool in hot climates.
Hence, Wild Hamsters like to sleep in underground burrows.
Because transfer need a lot of space and in the wild hamster are good diggers and construct deep dark underground burrows

Large crystalsCoarse textureEvidence of slow coolingWhat are igneous rocks?
Igneous rocks are one of the three main types of rocks, along with sedimentary and metamorphic rocks. They form from the solidification and cooling of magma or lava, which are molten materials that originate from deep within the Earth's mantle or from volcanic eruptions. As the magma or lava cools and solidifies, minerals crystallize and grow to form the various types of igneous rocks.
Igneous rocks can be classified into two main categories: intrusive and extrusive. Intrusive igneous rocks form below the Earth's surface when magma cools and solidifies slowly. These rocks have large crystals and a coarse-grained texture, as the slow cooling allows ample time for mineral crystals to grow. Examples of intrusive igneous rocks include granite, diorite, and gabbro.
Extrusive igneous rocks, on the other hand, form on or above the Earth's surface when lava cools and solidifies quickly. These rocks have small or no crystals and a fine-grained texture, as the rapid cooling prevents mineral crystals from growing. Examples of extrusive igneous rocks include basalt, andesite, and rhyolite.
Igneous rocks can also be further classified based on their mineral composition, texture, and other characteristics.

Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.

D.
mineral integration
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.

vacation.
They will select different types of seeds, such as beans, peas, or sunflower seeds.
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 pots.
They should observe and document the changes that occur over time, including the
emergence of roots and shoots.

The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.
