Answer: B :fossile fuel or narual gas
Includes fossil fuels and coal is best to complete the chart.
What is Renewable sources?Renewable energy comes from natural sources that replace themselves more quickly than they are used up. Examples of such sources that are continuously replenished are the sun and the wind. There are many different types of renewable energy available to us.
On the other hand, non-renewable fossil fuels like coal, oil, and gas require hundreds of millions of years to create. When fossil fuels are used to create energy, they emit dangerous greenhouse gases like carbon dioxide.
More emissions are produced by burning fossil fuels than by producing electricity from renewable sources. The key to solving the climate catastrophe is switching from fossil fuels, which now produce the majority of emissions, to renewable energy.
Therefore, Includes fossil fuels and coal is best to complete the chart.

A typical bag of fertilizer contains high levels of nitrogen, phosphorus, and potassium but trace amounts of magnesium and calcium. Which of the following best matches the fertilizer component with the molecule in which it will be incorporated by organisms in the area?
Answer:
This question is incomplete as it lacks options. The options are:
A) Nitrogen will be incorporated into nucleic acids.
B) Phosphorus will be incorporated into amino acids.
C) Potassium will be incorporated into lipids.
D) Magnesium will be incorporated into carbohydrates.
The answer is A. Nitrogen will be incorporated into nucleic acids.
Explanation:
Fertilizers serve as external source of nutrients as they contain certain elements necessary for the build up of biomolecules in living organisms. According to this question, the bag of fertilizer contains the following elemental components: nitrogen, phosphorus, potassium, magnesium and calcium.
These elemental components of the fertilizer will be incorporated by organisms and used to build biomolecules in their systems. The four biomolecules are carbohydrate, proteins, lipids and nucleic acid. NUCLEIC ACID is a complex biomolecule made up of simpler NUCLEOTIDE subunits. Each nucleotide is made up of a pentose sugar, phosphate group and NITROGENOUS BASE.
NITROGENOUS BASE is a base which principally contains NITROGEN in the core of its structure. Hence, nitrogen element is a vital component necessary for the formation of nucleic acids. Therefore, Nitrogen component of the fertilizer will be incorporated into nucleic acids of organisms in the area.
A) Nitrogen will be incorporated into nucleic acids is the correct option.
Nitrogen in the fertilizer will be incorporated into nucleic acids because nitrogen is the component of nucleic acid. Without nitrogen, nucleic acid will not be formed.
Nucleic acids include ribonucleic acid and deoxyribonucleic acid. Nitrogen is the main component of all biochemical compounds such as carbon, hydrogen, and oxygen, proteins and nucleic acids etc so we can conclude that nitrogen will be incorporated into nucleic acids.

Diffusion is movement of a molecule from an area of higher concentration to an area of lower concentration. True or false
Answer:
THIS IS TRUE
Explanation:
It is the area of higher concertation to an area lower concertation
True: Diffusion involves the movement of a molecule from an area of higher concentration to an area of lower concentration.
Diffusion can be defined as the movement of gas molecules from an area (region) of higher concentration to an area (region) of lower concentration, until an equilibrium is attained (reached) within the system.
This ultimately implies that, gas molecules generally move from higher concentration areas to lower concentration areas during diffusion.
In conclusion, diffusion makes it possible for gas molecules to move from an area (region) of higher concentration to an area (region) of lower concentration.

In Activity A, you explored photosynthesis in a pond. The dissolved oxygen in a pond is
produced by pond plants and algae (small, plant-like organisms) in a process called
photosynthesis.
What is the source of energy that is present during the time that photosynthesis takes
place?
Answer:
Photons
Explanation:
Photons are the only source of energy for photosynthesis. Photons are absorbed by chlorophyll molecules within Photosystems I and II (and antennae complexes), generating higher-energy ‘excited’ states of the photosystems which can carry out energetically costly chemical reactions.
Answer:
i am thinking the sun is the answer because the sun is usually the main source of energy that is included in photosynthesis

All organisms have adaptations for their environment. Identify two adaptations that could be useful for organisms that live in a desert biome but not in a tundra biome. Explain your reasoning.
Answer:
1) The ability to burrow under sand to protect themselves from heat
2) Adaptations to conserve water
Explanation:
Many animals have adapted to dessert biomes by burrowing under the sand to protect themselves from the heat. This ability would be useless in a tundra biome because it is very cold. To maintain homeostasis animals in the tundra biome often have thicker fur to keep themselves warm.
Another adaptation in the dessert biome is to conserve water. Plants and animals such as camels have structures to help them conserve water. For example a cactus stores the water from rain in its stem and a camel is able to save water in their hump. There are very little plants in the tundra biome, but this adaptation would be unnecessary for them.

Identify the substances that can readily pass through the inner mitochondrial membrane.
A. H2O.B. Small proteins.C. CO2.D. H+.E. O2.F. Pyruvate.
Answer:
A,C E
Explanation:
The inner membrane of the mitochondria separate the matrix of the mitochondria from the cytosol(inner membrane space.). It is invaginated folded inwards to form the critae. This is an adaptive feature to increase the surface area for biochemical reaction in the mitochondria.
The invagination gives two compartments the inner mitochondria also creates the outer intermembrane space and the inner matrix
These are the substances that can pass freely the inner membrane of the mitochondria.Pyruvate and H+ can not pass through.Specifically,it is not preamble to H+ because, hydrogen ions are needed to generate the electrochemical gradients needed for the chemical energy for phosphorylation of ADP by P to form ATPs by the enzyme ATPase synthase.If the inner membrane is permeable to H+ the electochemical gradient will not be produced, and therefore ATPs productions stops.
O2 needs to pass through the inner membrane because it it the final electron acceptor. Therefore if not allowed to pass through oxidative phosphorylation and ETC will nor occur.
CO2 must pass through because its accumulation will increase the acidity of the inner mitochondria

A researcher interested in predicting patterns of helping behavior using the concept of inclusive fitness would want to know ________. a. how strongly helping behavior in biological parents correlates with helping behavior in their offspring b. the similarity between adopted siblings on measures of helping behavior c. monozygotic (MZ) and dizygotic (DZ) correlations for helping behavior d. how much genetic material you share with someone you might hel
Answer:
d. how much genetic material you share with someone you might help
Explanation:
In family groups or populations there are certain behaviors that might have possitive effects on other individual´s fitness. These behavior are known as prosocial.
Prosocial behavior requires cooperation among individuals that are helping each other. Although sometimes this might implicate a sacrifice of the one that provides the help, in a long-term period the whole group will be beneficiated.
Altruist actions occur when one of the organisms help another one.
To explain these behaviors, Hamilton proposed an explanation for altruism as "inclusive fitness" (1964). According to this, an organism might help another one if this helps beneficiate its genes, that are shared with the organisms that receive help. The concept of inclusive fitness links the evolution of altruism with blood relationship. This means that helping relatives increases the reproductive success of the helping individual, as its genes are represented in the beneficiated relatives. Altruist acts occur to favor close relatives.
The inclusive fitness concept points to the strategy of an organism to ensure the maintenance of its genetic material in the population for a long period of time, even if it requires some kind of harm for itself or is in its detriment.
In organisms that reproduce sexually, in general, help is directed to the progeny, although it is not always like this.

As water moves from the roots up through the stem of a plant, adhesion is a property of water that enables this to happen. Which
characteristic of water causes adhesion?
Hydrogen bonds
Ability to change state
Solvent capabilities
O Cohesion.
Answer:Water molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. Cohesion helps plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. This transport occurs even in large trees and against gravity. Transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.
