An elephant lumbers across African grassland as
dust rises up from each of her steps. She finds a
giant tree and works to pierce its thick bark with
her tusks. She is prying and poking to get at
the water the tree often stores inside. This is no
ordinary tree but a baobab, a tree that looms large
in size and importance for both the animals and
people of Africa The baobab’s astonishing appearance alone proves
it is special. It can grow up to 60 feet high and
30 feet wide, soaring above most other life in the
dry savannah. The baobab has a wide barrel-like
trunk topped with shorter, twisted branches. It
only grows leaves for two short periods, giving the
branches the appearance of gnarled roots for most
of the year. In fact, some African legends say that
a god, angry at the baobab, decided to uproot and
replant it upside down. This remarkable tree survives dry conditions and
is found in many regions of Africa. Its roots spread
out up to a hundred feet away to gather needed
water. The adaptable sponge-like bark contracts in
dry months and expands in wet ones. Baobab trees
serve as a source of water, food, and a safe home
for a variety of animals. In particular, the whitebacked vulture, with a wingspan of about seven
feet, nests high in the baobab’s branches. The great
bird only nests once a year, laying just one egg. The
tall, strong baobab provides the ideal site for several
months of safety for the mother and baby vulture. For centuries, the baobab has also been
essential to the people in various parts of Africa,
many of whom call it the “Tree of Life.” The
baobab’s immense trunk is hollow, creating a
large circular chamber at the center. Baobab
chambers have been used as shelters, prisons,
and animal stables. The tree’s spinach-like
leaves can be eaten, and people use them for
both food and medicine. The fruit provides
a citrus-like refreshment. People strip off the
fibrous bark to make rope, cloth, roofing, and
paper. Unlike most other trees, the baobab can
endure this practice, regenerating its bark and
continuing to grow. Perhaps this is one reason baobabs have such
incredible longevity. Some have even been
known to live for over 2,000 years! These
amazing survivors continue to provide valuable
resources across 32 countries in Africa.
What idea(s) from the passage do the
elephant’s actions in paragraph 1 help
support? Check all that apply.
a-The baobab absorbs water.
b-The baobab provides a safe place to stay.
c- The baobab gives life to animals.
d- The baobab trunk is used for shelter.
e-The baobab lives for thousands of years.
Answer:

Describe the group of frogs in the image.
the frogs are all about the same size, varying in color and pattern.
The frogs are approximately the same size, but they exhibit a range of colors and patterns.
What is genetic variation?The size of the frogs being similar and varying in color and pattern may be due to genetic variation within the population. This means that the frogs have different genetic traits that determine their color and pattern, but they still share the same general body size due to the genetic makeup of the population.
It's also possible that environmental factors, such as diet or temperature, could play a role in color and pattern variation, but not necessarily in size variation. Additionally, if the frogs are from the same species, their overall body size would be expected to be relatively similar due to shared genetic traits that determine their basic body structure.

Propose an explanation for the wide diversity of minerals. Consider factors such as the elements that make up minerals and the Earth processes that form minerals.
Answer:
See
Explanation:
Minerals form in all geologic environments and thus under a wide range of chemical and physical conditions, such as varying temperature and pressure. The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which new minerals form at the expense of earlier ones owing to the effects of changing—usually increasing—temperature or pressure or both on some existing rock type, and (4) hydrothermal, in which minerals are chemically precipitated from hot solutions within Earth. The first three processes generally lead to varieties of rocks in which different mineral grains are closely intergrown in an interlocking fabric. Hydrothermal solutions, and even solutions at very low temperatures (e.g., groundwater), tend to follow fracture zones in rocks that may provide open spaces for the chemical precipitation of minerals from solution. It is from such open spaces, partially filled by minerals deposited from solutions, that most of the spectacular mineral specimens have been collected. If a mineral that is in the process of growth (as a result of precipitation) is allowed to develop in a free space, it will generally exhibit a well-developed crystal form, which adds to a specimen’s aesthetic beauty. Similarly, geodes, which are rounded, hollow, or partially hollow bodies commonly found in limestones, may contain well-formed crystals lining the central cavity. Geodes form as a result of mineral deposition from solutions such as groundwater.

Answer:
1. Antonie van Leeuwenhoek made the first microscope and used it to look at bacteria and study bacteria, and Robert Hooke studied cells and saw cavities in the cells that looked like small boxes - he discovered plant cells! he recognized cells as the basic unit of life, a basis for Cell Theory.
2. cell theory is: every living organism is made of one or more cells, cells are the smallest units of life ( that have the properties of a living thing), All cells come from other cells - all living things come from other living things. This relates to every living thing because all living things come under cell theory - like all living things are made of cells
3. prokaryotes, like bacteria, doesn't have a nucleus covered in a membrane. a eukaryotic cell, like an animal cell, has a membrane covered nucleus. just like the nucleus, in eukaryotes the organelles are not membrane bound. in prokaryotes, the organelles are membrane bound. In prokaryotes the DNA form is circular, while the DNA form in eukaryotes is linear. there are more, but i couldn't list them.
4. Example for prokaryote: the famous (or infamous) E. Coli bacterium. example for eukaryote: Humans!
5. Single-celled organisms (unicellular organisms) have all the functions necessary for their survival in the single cell. Multicellular organisms (many celled organisms), however, need many cells to survive and carry out all the functions necessary for their survival and do the different tasks each cell is supposed to do.

ASAP! When writing a research paper, look for credible sources. Science doesn’t show bias, but humans do. Avoid sites and articles that provide facts without citing proper scientific evidence. You must be able to identify reliable sites so that the data in your research paper is credible.
Use sources that end in .gov. These government sites are reliable sources. You can also use sites ending in .edu. They’re generally trustworthy, but sometimes students, not scientists, write content for .edu websites. Always identify the source’s author before proceeding. Some .org and .com sites are credible, but it’s important to verify their authenticity. When reviewing a source, ask these questions:
Who authored the document?
Is the author a genetics expert?
What is the document’s purpose?
Does the document state facts that scientists can prove with evidence?
Does the document include opinions?
How old is the document?
Do other credible sources support the document’s statements?
Search for credible websites and note the information they contain. Write down two sources that you’ll use for your research paper, and cite them using Modern Language Association (MLA) citation methods.

How can we predict the ways organisms will interact with each other in different ecosystems?
We can predict the ways organisms will interact with each other in different ecosystems by studying their ecological niches, including their roles, habitats, and relationships with other species.
What is ecosystem?Predicting the ways organisms will interact with each other in different ecosystems can be a complex task that requires a deep understanding of the ecology of the species involved. Scientists use various tools and techniques to make predictions about these interactions, including field observations, experiments, and mathematical models.
One approach is to analyze the functional traits of species, such as their feeding habits, mobility, and physiology, to infer how they will interact with each other and with their environment. Another approach is to use food web analysis, which maps out the complex network of interactions among species in an ecosystem. This can help identify key species that play critical roles in the ecosystem and understand how the removal or addition of a species may affect the overall ecosystem.
Computer simulations and modeling can also be used to predict the outcomes of different interactions and scenarios in ecosystems. However, because ecosystems are complex and dynamic, predictions are not always accurate and require ongoing monitoring and reassessment.

Answer:
Loggerhead Sea Turtle (Caretta)
Explanation:
The Loggerhead Sea Turtle is a sea turtle that lives across the Indian, Atlantic, and Pacific Oceans. They are also located in the Black sea and the Mediterranean Sea and most of the nesting beaches of these turtles occur across the western rims of the Indian and Atlantic Oceans. It was listed as a federally threatened species in 1978 owing to the destruction of its beach nesting habitat, harassment while nesting, overharvesting of its eggs, and bycatch death via commercial fishing gear. More than half the world's 7.5 billion people live within 150 miles of the coast, putting tremendous pressure on all different types of sea turtles trying to find space to live and reproduce. There are between 40,000 - 50,000 Loggerhead Sea Turtles left in the wild, but there are ways we can help this endangered species thrive again. We can reduce marine debris that may entangle or accidentally be eaten by the sea turtles, participate in clean-ups, and reduce plastic to keep our oceans and beaches clean. We can also use reusable items and stop releasing balloons, they might end up in the ocean and the turtles might accidentally eat or swallow them. You can even attend sea turtle watches that know how to safely observe nesting sea turtles. All in all, the Loggerhead Sea Turtle is a magnificent creature and we should do whatever we can to stop it from going extinct.
