Two processes needed for survival of life on this planet are cellular respiration and photosynthesis. How are cellular respiration and photosynthesis mutually dependent ?
A. Photosynthesis releases energy and cellular respiration stores energy.
B. Photosynthesis releases carbon dioxide and cellular respiration releases oxygen.
C. Photosynthesis removes oxygen from the atmosphere and cellular respiration replaces it.
D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.
???
Photosynthesis and respiration depend on each other and complement themselves. Option D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.
Why are Photosynthesis and respiration complementary processes?Photosynthesis occurs in chloroplasts, while respiration occurs in mitochondria.The photosynthetic process needs solar radiation to produce organic compounds, while the respiration process needs the organic compounds to obtain chemical energy.Photosynthesis transforms CO₂ into organic compounds, while respiration transforms organic compounds into CO₂.In the process of photosynthesis, it occurs a release of oxygen, which is then used during the respiration process. Both processes produce energy, which will be used in other cellular reactions.Respiration´s final products are CO₂, ATP, and waterPhotosynthesis´s final products are carbohydrates and oxygen.
The correct option is D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.

Some. produces variable traits depending on environmental conditions
Answer:
Some genes produces variable traits depending on environmental conditions
Explanation:
The interaction between some genes and environments confers on individuals different degrees of susceptibility in the appearance of a certain characteristic or in the expression of some variable traits. The trait appears in individuals who have reached a certain threshold, thus the variability in phenotypic expression could be related to the greater or lesser number of predisposing genes in each individual. The differential expression of genes depending on the environment is called the reaction norm, and it refers to genes that can be expressed in a different way in different individuals, depending on the environment in which those individuals develop. The norm of reaction is the set of pathways that a genotype can follow, in all favorable and unfavorable environments, until giving rise to the various possible phenotypes.

Explanation:
Match each movement with the correct label.
flexion
extension
adduction
abduction
elevation
depression
medial rotation
lateral rotation
Answer:
flexion - depression
extension - elevation
adduction - medial rotation
abduction - lateral rotation
Explanation:
Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.
Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.
Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.
Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.
The image shows a portion of the fossil record that spans several million years. In the image, the numbers designate different rock layers, with the number 1 corresponding to the oldest rock layer.
What statement provides the best explanation for the change in the species between rock layer 1 and rock layer 2?
A. An abrupt change in the environment caused the original species to evolve into several new species.
B. The original species hybridized with a single new species, resulting in a variety of species.
C. Humans introduced several new species into the environment after the original species had died out.
D. The original species died out, and several new species evolved that were better suited to the environment.
Answer:
answer is B
Explanation:
The original species died out, and several new species evolved that have desirable traits to survive in the changing environment. Therefore, the correct statement is option D.
What is theory of evolution?There are changes in species among different rock layers when the fossils are studied. Fossils are the preserved remains of living organisms from the past, and they provide information regarding different types of organisms lived during that particular period of time.
Scientists have found different fossils in different layers representing different groups of organisms. Various factors are responsible for these changes, including environmental changes, competition, genetic drift, etc.
Theory of evolution states that species evolve from time to time through natural selection, where individuals with desirable traits have high chances to survive. Therefore, the original species in rock layer 1 did not survive in the changing environmental conditions, and they died. However, new species evolved that were better suited to the new environment and have high chances of survival due to natural selection and adaptation.
Therefore, original species died, and new species evolved that were better suited to the environment.

1. are marsupials discussed to prove against biogeography/ geographic distribution. SHOW YOUR EXPLANATION!!
Answer:Marsupial mammals on Australia likely evolved from a common ancestor. ... Because Australia was isolated by water for millions of years, these species were able to evolve without competition from (or exchange with) mammal species elsewhere in the world.
Explanation:
Answer:
Biogeography is the study of the geographical distributions of biological organisms. For scientists who study evolution, biogeography is often an important part of their analysis, because it provides compelling proof for their theory. This is because many geographical features, such as oceans, rivers, mountains and islands, provide barriers to species, allowing scientists to observe how they evolve separately from one another.

why is there is no point in adding more generations when an allele has become fixed
Answer:
Low genetic diversity, which is seen with allele fixation, is dangerous as it can lead to mass extinctions. If there is little genetic variability within a population and the genetically similar individuals all are susceptible to a certain pathogen, the population will likely cease to exist. This is why we see examples of populations with fixed alleles becoming threatened or endangered
Explanation:
basically, it will cause extinction

The thing that makes a wave a wave is that it___________from one place to another.
A. Transport energy
B. Transports the medium
C. Travels with a vacuum
D. Carries Solids
Answer:
A?
Explanation:
All waves carry energy from one location to another, but they do not move any physical objects. The energy is transferred from one particle to the next, which then oscillates as well. Thus, option A is correct.
What is the energy transport property of wave?The vibration of particles, which transfers energy in waves, causes the particles to travel perpendicular to the wave's horizontal movement. As the particles transition from rest to movement and back to rest, energy is changed between potential (stored) and kinetic (moving) energy.
However, waves do not move mass. By colliding with one another and exchanging energy, the particles “participate” in the wave. Because of this, energy can be transferred even when the particles' average positions remain unchanged.
Therefore, The thing that makes a wave is that it transport energy from one place to another.

Hope I helped and have a great day ∩^·ω·^∩ !
Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises.
What variable that influence the rate of cellular respiration?Since all living cells require both glucose and oxygen to operate properly, variations in the concentration of glucose have an effect on the rate of cellular respiration. If a cell's glucose level is low, it cannot produce energy in the form of ATP molecules.
High oxygen concentrations enable cells to perform aerobic respiration, which uses oxygen to build ATP and generates more ATP than anaerobic respiration, which occurs when oxygen is not present.
As a result, increased cellular respiration is often associated with warmer temperatures.
Therefore, Oxygen Concentration, Temperature, Glucose Availability
