Which of the following would likely move through the phospholipids of the
cell membrane most easily? *
CO2
Glucose
K+
Starch
Answer:
CO2
Explanation:
Oxygen and CO2 can move through the cell membrane through simple diffusion because they are small molecules.
It's possible that CO2 travels through the lipid bilayer far more quickly than any other molecule. Therefore, option (A) is correct.
What is the structure of cell membrane ?According to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane.
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
Therefore, small and simple molecules like water, H2O , CO2 can pass through the cell membrane easily as it is partially permeable.

Speciation, which leads to diversity among species through natural
selection, occurs when
Once similar species are no longer able to mate and produce fertile
offspring
Organisms develop characteristics that mimic traits of a completely
different species.
Species experience change within their lineage and develop new
characteristics.
Species interact with other species in an ecosystem and develop
similar traits to each other.
Answer:
Natural selection and speciation: 'Ecological speciation'. ... Natural selection is generally recognized as a central mechanism of evolutionary change within species. Thus, natural selection plays a major role in generating the array of phenotypic and genetic diversity observed in nature.

What is crossing over?When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up.
The same genes may be present on the two chromosomes in different versions. The genetic material in the germ line can switch places, a process is known as crossing over.
Pairs of chromosomes from each parent align to allow similar DNA sequences from the paired chromosomes to cross over one another during the development of egg and sperm cells, commonly known as meiosis.
Therefore, the percentage that will be speckled is 20%.

Describe THREE examples of the effect of altitude on animals.(life science)
Altitude is an elevation from the sea level. It plays an important role in animals as it affects the respiratory rate, pressure on the cells, and homeostasis.
What is the respiratory rate?Respiratory rate is the breathing that involves the inhalation and exhalation of gases through the respiratory system. The breathing rate is reduced due to decreases in oxygen transport at a higher altitude which causes fatigue.
At higher altitudes, the pressure is more and in turn, affects the cells as the body also maintains an osmotic pressure to balance the fluid and internal organs. As the altitude increases the temperature drops which affects the homeostasis of the body resulting in more use of energy to keep warm.
Therefore, altitude affects respiration, cell pressure, and homeostasis.

4. What are sensory organs and what type of stimuli do these receptors respond to?
5. What is an explanation of how the information from stimuli is communicated to the brain?
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
Hello, 3Coli Here!
Here are your answers:
1. What is a stimulus?
Stimulus is a natural body reaction caused by changes in the environment around or inside the organism. This is a response from the brain.
2. Why does the body respond to stimuli?
The body responds to stimuli, because it needs to protect itself.
3. What are some different types of stimuli?
The two main types of stimuli are external stimuli and internal stimuli. External stimuli are reactions triggered by changes that occur outside of the body, while internal stimuli are reactions triggered by changes inside of the body.
4. What are sensory organs and what type of stimuli do these receptors respond to?
The most commonly used sensory organs include Eyes, Ears, Tongue, Nose, and Skin. Eyes respond to light and motion, because they are used to see. Ears respond to sound, because they hear. The tongue is used to taste, so it senses flavors. The nose is used to smell, so it responds to scents. Finally, the skin is used to feel, so it responds to whatever it feels.
5. What is an explanation of how the information from stimuli is communicated to the brain?
Neuron receptors convert internal and external environments into electrical signals, and then is sent to the brain through nerves.
6. What is a description of the two things that can happen when the brain processes the information from stimuli?
After the brain receives the signal, it will provide a response. One type of response is that the body will physically react to the change. The second type of response is to avoid the change.
