Answer: Single-celled organisms increase atmospheric methane concentrations. Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve.
2. Which forms of life were dominant in the Mesozoic era?
Answer: Reptiles
3. How did the success of photosynthetic bacteria change Earth’s atmosphere?
Answer: increased oxygen concentration
4. How did reduced methane concentrations in the atmosphere affect Earth?
Answer: Earth cooled.
5. Which characteristic defines the Paleozoic era?
Answer: Animals with shells and hard parts were dominant for the first time.
You're welcome.
Answer:
Earth cooled.
Explanation:
The reduced methane concentrations in the atmosphere affect Earth :
Particles of gas and dust released into the atmosphere during a volcanic eruption affect the climate. Most of the particles emitted by the volcano cool the planet by blocking incoming solar radiation. The cooling effect can last from months to years, depending on the nature of the eruption.Therefore, the Earth is cooled.

Which of the following correctly describes one way that cellular respiration contributes to the carbon cycle?
Choose 1 answer:
Choose 1 answer:
(Choice A)
A
Cellular respiration breaks down carbon-based molecules and releases oxygen into the atmosphere.
(Choice B)
B
Cellular respiration takes carbon dioxide from the atmosphere and uses it to make carbon-based molecules that are stored as biomass.
(Choice C)
C
Cellular respiration helps move carbon from the bodies of living organisms into the atmosphere.
Answer:
Choice A
Explanation:
Recall that trees release oxygen as a byproduct of photosynthesis. And you need oxygen to breathe. Do you know why? So your cells can perform cellular respiration and make ATP.
Cellular respiration contributes to the carbon cycle as cellular respiration helps move carbon from the bodies of living organisms into the atmosphere.
How does cellular respiration contribute to the carbon cycle?
During cellular respiration, organic molecules are broken down using oxygen molecule and carbon dioxide is released into environment.
This carbon dioxide is used by plants during photosynthesis and they synthesize organic matter.
This is how respiration contributes to carbon cycle.

What’s the term to describe a mutant viral protein without a genetic code that can cause disease?
Answer:
'Prion' is a term first used to describe the mysterious infectious agent responsible for several neurodegenerative diseases found in mammals, including Creutzfeldt-Jakob disease (CJD) in humans.
Explanation:
The term to describe a mutant viral protein without a genetic code that can cause disease is a "prion." Prions are abnormal forms of proteins that can induce misfolding of normal proteins, so option a is correct option.
The misfolded prion protein can convert normal proteins of the same type into the abnormal misfolded form of protein, leading to a chain reaction and accumulation of misfolded proteins. This can cause damage to brain tissue and result in the characteristic symptoms associated with prion diseases, which include changes in behavior, neurological dysfunction, and ultimately, severe neurological degeneration. so option a is correct option.

Coronary heart disease is the main cause of death in our country. The following factors can increase the risk of an individual contracting this disease:
-smoking
-unbalanced diet
-unhealthy lifestyle
Explain how these factors can contribute to coronary heart disease.
Smoking :-
The coronary arteries inside us are responsible for supplying our heart muscles with O₂ rich blood. When people smoke, plaque builds up in the arteries & the O₂ rich blood will not get supplied to the hear muscles causing atherosclerosis / coronary heart disease.
Unbalanced Diet :-
Eating an unhealthy diet which is high in cholesterol & fats also causes atherosclerosis (coronary heart disease). Too much salt in the diet can also raise blood pressure which is another factor responsible for this disease.
Unhealthy Lifestyle :-
Unhealthy lifestyles like not exercising at all & being obese lead to atherosclerosis (coronary heart disease).

Which of the following will impact a populations equilibrium ?
. Random Mating
. No mutations
. Small population
. No Migration
Answer:
". Small population"
Explanation:
The conditions to maintain the (Hardy-Weinberg) equilibrium are no mutation, no gene flow, a large population size, random mating, and no natural selection. This can be disrupted by changes from any of its five main factors. No migration, no mutations, and random mating are all a part of this equilibrium, so the answer will be a small population.

What effect does viscosity have on blood flow?
A.) Low blood viscosity leads to slower blood flow.
B.) High blood viscosity leads to slower blood flow.
C.) Low blood viscosity increases resistance and leads to fast blood flow.
D.) High blood viscosity decreases resistance and leads to fast blood flow.
Answer:
B
Explanation:
High blood viscosity leads to slower blood flow. Therefore, option B is correct.
What is viscosity?Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction between different layers of fluid as they move relative to one another. In general, fluids with high viscosity flow more slowly than fluids with low viscosity.
Viscosity can affect blood flow by altering the resistance to blood flow in blood vessels. Blood viscosity is influenced by the thickness and stickiness of blood, which is determined by the concentration of various proteins and cells in the blood.
When blood viscosity is high, the blood is thicker and flows more slowly, which can increase the resistance to blood flow in blood vessels. Therefore, option B is correct.

Which cellular component is considered an organelle?
Answer:
Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles. Ribosomes are not enclosed within a membrane but are still commonly referred to as organelles in eukaryotic cells. Membrane-bound organelles. Membrane-bound organelles are cellular structures that are bound by biological membrane. Examples of membrane-bound organelles are nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes and vacuoles.
Have a great day friend! :D
Answer:
Organelles play an important role in a variety of cell processes. The nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles are all organelles found in animal cells. Although ribosomes are not surrounded by a membrane, they are nonetheless referred to as organelles in eukaryotic cells.
Explanation:
ORGANELLESAn organelle is a specialized subunit of a cell that has a defined role in cell biology. The name organelle stems from the idea that these structures are sections of cells, similar to how organs are parts of the body, therefore the diminutive suffix -elle. Organelles are either independent lipid bilayer-enclosed functional units (also known as membrane-bound organelles) or spatially distinct functional units without a lipid bilayer surrounding them (non-membrane bound organelles). Although most organelles are functional units within cells, some functional units that extend outside of cells, such as cilia, the flagellum and archaellum, and the trichocyst, are often referred to as organelles.Learn more about Organelles here
