What two scientific theories support the Big Bang?
Answer:
Two major scientific discoveries provide strong support for the Big Bang theory: • Hubble's discovery in the 1920s of a relationship between a galaxy's distance from Earth and its speed; and • the discovery in the 1960s of cosmic microwave background radiation.
Explanation:
hope this helps :)
Two major scientific discoveries provide strong support for the Big Bang theory:
• Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed
• the discovery in the 1960s of cosmic microwave background radiation.
1. Hubble’s discoveryin 1924 astronomer Edwin Hubble used a technique pioneered by Henrietta Leavitt to measure distances to remote objects in the sky.Hubble used spectroscopic red-shift data to measure the speeds these objects were travelling then graphed their distance from Earth against their speed.He discovered that the speed at which astronomical objects move apart is proportional to their distance from each other2. discovery in the 1960s of cosmic microwave background radiationOn May 20, 1964, American radio astronomers Robert Wilson and Arno Penzias discovered the cosmic microwave background radiation (CMB)It states that the ancient light that began saturating the universe 380,000 years after its creation.It also supports the big bang theoryThus, Two major scientific discoveries provide strong support for the Big Bang theory:
• Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed
• the discovery in the 1960s of cosmic microwave background radiation.

These ecological levels of organization are ranked in ascending order as follows: D. individual → population→ community→ ecosystem.
What is an ecosystem?An ecosystem can be defined as a biological community that is typically made up of living organisms (biotic factors) such as individuals and the physical environment (abiotic factors) in which they interact.
Basically, the individual organisms in an ecosystem forms a population and this also gives rise to a community. This ultimately implies that, the ecological levels of organization are ranked in ascending order as follows:

How are land breezes and sea breezes different?
Answer:
Land breezes come from land while sea breezes come from the ocean or other large bodies of water. The key difference is due to the property of water to retain heat and warm up longer as compared to land. Land breezes are also known as off-shore winds while sea breezes are also called on-shore winds.
Explanation:
Land breeze blows during the night from land to sea and the land becomes cooler faster than the sea. The air above the sea becomes less dense (i.e. warmer) and rises. The cooler air from the land moves in to take its place. Sea breeze: Sea breeze blows during the day and the land heats up faster than the sea.
Explain how bacteria are both helpful and harmful to our bodies.
Requirements: A paragraph with enough details.
Prize: 10 Points and Brainliest for best (& original) answer!
Sample Response:
Bacteria are helpful because they produce oxygen, which our bodies need to breathe, and they help us to digest the food we eat. Bacteria are also helpful because they are used in medicine to help us overcome disease. Bacteria are harmful because they can cause tooth decay and illnesses that can be either common or quite serious.
This is a sample response, so it's 100% correct. Peace!
Hello! Here is your answer: Bacteria can be good, because they help produce oxygen, decompose waste, and help in medicine. They also help us digest food and live. Some other bacteria are harmful, because they can cause harmful diseases.

Hypoxic environments have very little oxygen in them. In the most extreme cases,
they may have no oxygen at all. What process must cells in these environments use to
get the energy needed for life processes out of the food molecules they take in?
A photosynthesis C. anaerobic respiration
B. aerobic respiration D. Osmosis
Answer:
The process cells must use in hypoxic environments to obtain energy from the food molecules they take in is anaerobic respiration (option C).
Explanation:
Anaerobic respiration is the process of energy production that cells carry out in the absence of oxygen. This type of reaction requires an electron acceptor other than oxygen.
Some microorganisms, such as bacteria, can carry out their metabolism in environments with little or no oxygen. In these organisms, the energy-producing pathways are anaerobic respiration and fermentation reactions.
The other options are not correct because:
A. Photosynthesis: occurs in plants, and is based on the conversion of solar energy into chemical energy.
B. Aerobic respiration: requires the presence of oxygen, the final electron acceptor of the electron transport chain.
D. Osmosis: is a transmembrane transport mechanism.

Which type of dating uses radioactive isotopes to give us the age of a
fossil?
Answer:
Radiometric dating
Explanation:
Answer:
radiometric dating
Explanation:
Some minerals in rocks and organic matter (e.g., wood, bones, and shells) can contain radioactive isotopes. The abundances of parent and daughter isotopes in a sample can be measured and used to determine their age. This method is known as radiometric dating.

Explanation:
Why do you think the strand of DNA
coming in from the left side of the screen
is becoming two thinner strands?
Answer:
they might be spliting(reproduction) to make offspring
Explanation:
DNA replication
What does it mean when DNA splits?
Two strands of DNA come together to form a twisted, ladder-like structure. Hydrogen bonds between the bases of each strand create the double-stranded structure. The cell must split the two strands to allow the replication machinery to access each strand and copy it.
What causes the DNA to split apart during replication?
In order to unwind DNA, these interactions between base pairs must be broken. This is performed by an enzyme known as DNA helicase. DNA helicase disrupts the hydrogen bonding between base pairs to separate the strands into a Y shape known as the replication fork.
