Predict the movement of water in the picture
Answer:
The water will move out of the cell
Explanation:
This is due to osmosis. We can infer that there is some solute outside that is making the water outside into 75%. As from rules of osmosis, higher concentrations of water will move to lower concentrations of water. So, since the cell has a higher water percentage, water will move from the cell to the outside environment to maintain homeostasis.

Scientists have observed that in the Antarctic ecosystem Adélie and Chinstrap penguin populations have decreased in the past 40 years by about half. However, Gentoo penguin populations have remained steady and are possibly increasing. Increasing ocean temperatures in the Antarctic is resulting in less sea ice and less krill because krill depend on sea ice.
Which statement, if true, BEST explains why Gentoo penguins have a survival advantage in the changing Antarctic environment?
A.
Adult Gentoo penguins average about 0.5 kilograms more in weight than adult Adélie and Chinstrap penguins.
B.
Leopard seals prey heavily upon juvenile penguins.
C.
Gentoo penguins eat more types of prey than either Adélie or Chinstrap penguins.
D.
Penguins spend a large amount of their energy on keeping warm during harsh winters with very low temperatures.
Answer:
C.
Gentoo penguins eat more types of prey than either Adélie or Chinstrap penguins.

In terms of atomic structure, how are the elements of a periodic table group related?
If you take a look at the s-, p-, and d-block elements part of the periodic table, you'll see that they are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. And because of this, elements in the same group often display similar properties and reactivity.

Assume all of the presynaptic synapses identified produce epsps. If two of these synapses fired simultaneously, which synaptic combination brings the initial segment closest to threshold based on spatial summation? click on the appropriate synapses.
Based on spatial summation, the synapses closest to each other will brings the initial segment closest to threshold.
What are Excitatory Post-Synaptic Potentials, EPSPs?Excitatory Post-Synaptic Potentials, EPSP, are postsynaptic potential changes that are induced by neurotransmitters which depolarizes the cell, and hence increases the likelihood of initiating a postsynaptic action potential.
Based on spatial arrangement, the summation of two simultaneously fired synapses that is greater than or close to threshold potential will produce an action potential.
Therefore, the synapses closest to each other will brings the initial segment closest to threshold.

How do species change over time to adjust to varying conditions?
if we have red veins and red blood how do we have blue veins in our bodies FIRST ONE TO ANSWER AND EXPLAIN GETS BRAINILEST PLEASE HELP
Answer:
The colors we see are the result of which wavelengths of light are reflected back to our eyes. Veins appear blue because blue light is reflected back to our eyes.
Blue light does not penetrate human tissue as deeply as red light does. As a result, veins that are close to the surface of the skin will be more likely to reflect blue light back to the eye.”
In short, our veins appear blue because of a trick that light plays on our eyes and how the light interacts with our body and skin. All color works this way as light is a combination of all colors and when it reflects off of certain materials, it absorbs some colors and bounces back others to our eyes.

Explain why most humans require a supply of glucose.
Answer:
Nerve cells and chemical messengers there need it to help them process information so basically without it your brain wouldn't be able to work well
Explanation:
Most humans require a supply of glucose because Nerve cells and chemical messengers they need it to help them process information. Without it, your brain wouldn't be able to work well.
Why do we need glucose everyday?
Glucose provides energy for physiological processes such as respiration, heart rhythm and the regulation of body temperature.
Why is glucose required in the cell?
Glucose provides quick energy for cells. Fat has more energy than glucose, but it requires some chemical conversions before we can get it into the process of cellular respiration, so it takes longer to use.

What type of fuel does each energy system produce?.
Answer:
carbon?
Explanation:
Energy systems produce ATP, during every process cellular respiration is the major process of the system.
How ATP as fuel produce by each energy system?During cellular respiration, all the metabolic intermediates finally produce ATP, and in glycolysis, the Kreb cycle produces reducing products which finally oxidize in the electron transport chain.
The electron transport chain produces fuel as ATP, it is an enzymatic chain reaction that produces an electromotive force that is responsible for the production of ATP.
ATP is a major fuel for every cellular process which acts as an energy form that is extracted from metabolic intermediates.
Therefore ATP is a major fuel produced by the system.

Water has several properties that make it unique amongst compounds and make it possible for all forms of known life to function. The graph provided depicts what happens to the density of water as the temperature gets colder. According to the graph, what happens to the water’s density as it freezes and why? (SC.912. L.18.12)
When the temperature of the water finally goes below 4°C, the density of water decreases and as a result ice does not sink. The surface water freezes at 0°C while the lower part remains at 4°C
When the temperature of the water finally goes below 4°C, the density of water increases and as a result, ice doesn’t sink. The surface water freezes at 0°C and the water below freezes as well, allowing life to exist below frozen lakes
Water continues to get denser as the temperature get colder
The properties of cohesion and adhesion are directly responsible for water expansion at 4°C allowing aquatic life to survive under frozen lakes
Water’s density increases as it freezes or at lower temperature which is a unique property of water that enables aquatic animals to survive.
How cold water has more density?Cool water has more density because cooling a substance leads to molecules to slow down and get closer to one another, occupying a smaller volume that results in an increase in density while on the other hand, the warm water is less denser and will float on room-temperature water.
So we can conclude that cold water is more dense and will sink in room-temperature water.

The sum of the genetic traits in this population is called its V gene pooly. COMPLETE In guinea pigs, fur length is controlled by one gene. The Fallele generates long fur and the f allele generates short fur. Because only one F copy is needed to show the trait, if a guinea pig has the FF or Ff allele combination, they will have long fur. If they have the ff allele combination, they will have short fur. There is a total of 7 8 alleles in this population, There are 5 Falleles in the population. There are 3 ✓ falleles in the population. Look at the data for a guinea pig population to answer the following questions. COMPLETE Guinea pig 1: Long fur (FF) Guinea pig 2: Short fur (ff) If having long fur helps a guinea pig survive, what would you expect to see change in the population as it evolves? Guinea pig 3: Long fur (FF) DONE Cuinas nin 1. Innn fuar (Cf)
If having long fur helps a guinea pig survive, then it is expected to see the F allele is more common in the population as it evolves.
What is natural selection?Natural selection can be defined as the process of differential survival and reproduction of the fittest organisms.
The fittest organisms are life forms that have allele combinations favoring their survival and reproduction.
In this case, the F allele is an adaptive allele associated with higher fitness in the population.
