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.

dividing by 1.8. What is the Celsius temperature outside on a warm day (88°F)?
100
Explanation:
because of the temperature
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.

What is some strengths as a math learner
A medicine to remove the redness in eyes was tested in a group of 100 students. Each student took either the medicine or a placebo in both eyes. The participants were given some free time after receiving their drops. The researcher did not keep track of what they did in that free time. It turns out that many of the people receiving the medicine spent their time outside and many of the people receiving the placebo spent their time inside. The results may now be biased because the variable location (inside vs. outside) is now a/an ____ variable.
Answer:
Independent variable
Explanation:
In a scientific experiment, an independent variable is that variable which the experimenter changes or manipulates in order to effect an outcome. Only one independent variable should be tested at a time in a good experiment, all other variables should be kept constant. The initial independent variable in this experiment is TYPE OF SUBSTANCE put in the students' eyes.
However, according to the question, the researcher did not keep track of what they did in that free time. Hence, many of the people receiving the medicine spent their time outside and many of the people receiving the placebo spent their time inside. The location of every student should be a CONSTANT VARIABLE i.e. same for all students but now it has become an INDEPENDENT VARIABLE because it has been changed.

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.

In this activity, you will research the genetic diversity in two fish variants. The Mexican tetra (Astyanax mexicanus) has two notable variations: the surface variety and the blind cave fish variety. In this activity, you’ll use credible websites to find the following information about these two fish:
What type of habitat does each fish live in?
How do their physical characteristics differ?
How are they similar?
Can the two types mate with each other?
Why are their characteristics advantageous to their environments?
When you’ve found the information, answer the following questions.
Part A :
What are the similarities and differences between the two fish varieties?
Part B:
Do you think these fish are an example of natural selection among two populations of the same species? Explain your answer.
Part C:
Explain how the characteristics of the two types of fish relate to the genetic diversity of the species.
Answer:
Part A-One of the variations have eyes as well as some pigmentation on them. They live near the surface of the water. The other variation does not have eyes and are often albinos. I found that these fish live in deep, dark caves.
Part B-Yes. I think that these fish are an example of natural selection. The blind fish live in caves and eyes take up energy that could be used somewhere else in the fish. So, they developed into fish with no eyes, allowing them to function more efficiently.
Part C- As a species, they have genetic diversity because the two populations have separate genes. The two fish types developed different traits because of their separate habitats.

:D
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.

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.

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.

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.
