Complete the following statements to accurately describe examples of organisms affecting the Earth’s atmosphere, and subsequent

effects on other living organisms.
Starting around 2.7 billion years ago, photosynthesis by cyanobacteria, and later plants, pumped( Carbon dioxide, methane, O2) into the atmosphere. This caused the decline of anaerobic bacteria and allowed the rise and diversification of animals as seen in the (Cambrian, Carboniferous, Cretaceous) event around 500 million years ago.

Early vascular plants ( Captured, Released ) CO2 starting before the (Cambrian, Carboniferous, Cretaceous ) period that began around 350 million years ago, leading to lower temperatures and allowing the seed plants to outcompete seedless plants.

Modern human activity has raised (carbon dioxide, methane, oxygen) levels in the atmosphere to over(20%, 40%, 200ppm, 400ppm)., leading to higher temperatures, and contributing to extinctions of other specie

How do cricket communicate temperature and reactions and body parts allow them to do this?
aleksley [76]

Answer:

as temperature rises, mussles in a crickets body contract more, causing it to chirp more often

Explanation:Crickets, like all living things, have many chemical reactions going on inside their bodies, such as reactions that allow muscles to contract to produce chirping. Crickets, like all insects, are cold-blooded and take on the temperature of their surroundings. This affects how quickly these chemical muscle reactions can occur. Specifically, a formula called the Arrhenius equation describes the activation, or threshold, energy required to make these reactions occur. As the temperature rises, it becomes easier to reach a certain activation energy, thereby allowing chemical reactions, such as the ones that allow a cricket to chirp, to occur more rapidly.

Drag labels to the appropriate locations in this diagram.
Vinil7 [7]

Answer:

c = Enzymatic activity

e = Attachment to ECM and cytoskeleton

f = Signal reception and relay

g = Transport

h = Intercellular junctions

i = Cell-cell recognition

a = Phospholipid bilayer

b = Fibers of extracellular matrix (ECM)

d = Microfilaments of cytoskeletons

Explanation:

c) Enzymatic activity is an indication of the amount of active enzymes present to increase a reaction rate

e) Attachment to ECM and cytoskeleton is enabled by integrins that take signals from the ECM and control signaling pathways of the cell

f) Signal reception and relay is the transduction of signal

g) Transport is the movement of matter in and out of the cell through the cell membrane

h) Intercellular junctions are the contact regions between adjacent cells and plasma membrane

i) Cell-cell recognition is power of the cell to decipher the different neighboring cells in the cell's environment

a) Phospholipid bilayer consists of a hydrophobic interior and a hydrophilic exterior

b) Fibers of extracellular matrix (ECM) are ECM associated the cell

d) Microfilaments of cytoskeletons consist of actin and aid in cellular movement.

Mutation is an important mechanism for evolutionary change. Which type of mutations contribute to evolution?
Aneli [31]
<span>Both somatic and germinal mutations are contributors of evolution. Somatic mutations occur within tissues of individuals that give the said individual differing traits and characteristics. Germinal mutations occur in reproductive cells that can be passed on to offspring, altering their traits and characteristics.</span>

melomori [17]

The movement into or out of a population is  known as migration.

<h3>What is migration?</h3>

Often, individuals in a population have new individuals that join the population or leave the population. In fact some species have seasons of the year in which they move from one location to another.

The movement into or out of a population as described above is otherwise known as migration.
