Explanation:
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
Cohesin protein. Select all that apply. Select all that apply. It comprises filaments in mitotic and meiotic spindles. It prevents sister chromatid separation until anaphase of mitosis or anaphase II or meiosis. It is required for the segregation of chromosomes during anaphase of mitosis or meiosis. It is important for maintaining homologous chromosome pairing and plays a role in recombination. It holds sister chromatids together after chromosome replication.
Answer:
It prevents sister chromatid separation until anaphase of mitosis or anaphase II of meiosisIt is important for maintaining homologous chromosome pairing and plays a role in recombination.It holds sister chromatids together after chromosome replication.Explanation:
Cohesin proteins are many protein subunits united and forming a complex that plays an important role in mitosis and meiosis. These complexes have many functions and are involved in DNI repairing or genetic expression, among others. But one of the most known functions is the one of keeping sister chromatids together during cellular division.
This function can be accomplished since the S phase of cellular division when chromosomes are replicated. The two new copies must stay together during the G2 phase and the cohesin proteins are the ones in charge of doing so until it is needed. During the G2 phase of mitosis, sister chromatids are held together until they reach the Anaphase, during which other enzymes are activated to break the bonds and separate the chromatids. During the G2 phase of meiosis, sister chromatids and homologous chromosomes are held together by the cohesin proteins. Homologous chromosomes must be together until crossing over is completed, and cohesin proteins play an important role in making in possible. After the firsts stages of meiosis, sister Chromatids get completely separated in Anaphase II. During this phase it occurs the same as in mitosis, bonds break and chromatids get separated and go forward each cellular pole.Statements that are correct as regards Cohesin protein are,:
It prevents sister chromatid separation until anaphase of mitosis or anaphase II of meiosis
It is important for maintaining homologous chromosome pairing and plays a role in recombination.
It holds sister chromatids together after chromosome replication.
Cohesin can be regarded as a protein complex which brings about mediation of sister chromatid cohesion as well as as homologous recombination, and DNA looping. It usually holds sister chromatids together when chromosome replication has been done.Therefore, Cohesin is essential in maintaining homologous chromosome pairing.

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.

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.

Cytokinesis is the process of division of cytoplasm. The correct answer is cytokinesis.
The primary method of reproduction for unicellular organisms, cytokinesis also occurs during the growth and repair of tissues in higher plants and animals, as well as during the development of the embryo. Whether in mitosis or meiosis, it typically happens after nuclear doubling. Prokaryotes primarily reproduce by binary fission, in which the mother cell grows until it physically splits into two identical daughter cells through a process called cytokinesis.
Actin and myosin, the proteins involved in muscle contraction and other types of cell movement, form a ring around the cell to constrict it, causing cytokinesis to occur in animal cells. The formation of a new cell wall, known as the cell plate, between the two daughter cells divides the cytoplasm in plant cells. Following the division of the daughter cells, cellulose synthesis starts, and the cell plate develops into the primary cell wall.
Therefore, in any cell the cytoplasm, divides by cytokinesis. The correct answer is option c i.e. cytokinesis.

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.

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.

Temperature in degrees Fahrenheit can be converted to Celsius by first subtracting 32, then dividing by 1.8. What is the Celsius temperature outside on a warm day 100.
What is temperature?
Temperature is a unit used to describe hotness or coldness. It can be stated in terms of any number of arbitrary scales and shows the direction in which heat energy will naturally flow, i.e., from a hotter body to a colder body (one at a lower temperature).
Temperature is not the same as the energy of a thermodynamic system; for instance, an iceberg has a significantly larger total heat energy than a match, despite the fact that a match is burning at a much higher temperature.
As opposed to extensive characteristics, like mass or volume, temperature is referred to as an intense property—one that is independent of the quantity of matter being considered—along with pressure, density, and other comparable properties.
Therefore, Temperature in degrees Fahrenheit can be converted to Celsius by first subtracting 32, then dividing by 1.8. What is the Celsius temperature outside on a warm day 100.
