Answers
Answer:
It provides nutrients and gases to cell.
Explanation:
Osmosis is very important for the survival of a cell because due to osmosis, nutrients, water and gases enters in the cell. Osmosis is a type of diffusion in which solutes enters inside the cell through a semi-permeable membrane. This semi-permeable membrane only allows micromolecules such as glucose while does not allow to enter macromolecules such as carbohydrates and proteins due to small size of the holes of semi-permeable membrane.
Osmosis is important to the survival of a cell because it's the primary means through which water is transported in and out of cells.
Osmosis refers to the net movement of solvent molecules from a side of a semi-permeable membrane to another side.
Osmosis is important in living organisms as it helps in influencing the distribution of nutrients. Also, osmosis is vital for the release of metabolic waste products.

Given figure represents ulna bone of forearm.
The ulna bone is one of the two long bones located in the forearm, the other being the radius bone. The ulna is situated on the medial side of the forearm and is slightly longer than the radius. The bone extends from the elbow joint to the wrist joint, where it articulates with the radius and several carpal bones to form the wrist joint.
The ulna bone is composed of several distinctive features, including:
1. Olecranon: The olecranon is a bony prominence located at the proximal end of the ulna bone that serves as the attachment site for several muscles in the arm.
Trochlear notch: The trochlear notch is a U-shaped depression on the distal end of the ulna bone that articulates with the trochlea of the humerus to form the elbow joint.
3. Styloid process: The styloid process is a bony projection located on the distal end of the ulna bone that serves as the attachment site for ligaments that connect the bone to the wrist joint.
4. Interosseous membrane: The interosseous membrane is a fibrous membrane that connects the ulna and radius bones and helps to transmit forces between the bones during movements of the forearm.
The ulna bone plays an important role in the stability and movement of the forearm and wrist joints, and it is essential for the performance of many everyday activities.

Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. Where in the branching tree would you most likely write "lives on land during all life stages"? Explain your answer.
Answers
"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."
SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.
Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

Heterozygous Alleles are said to be silent carriers of a trait. What does this mean?
If two heterozygous parents each pass on a recessive allele their offspring will show a recessive
phenotype
O A Heterozygous individual will always show the recessive trait
O They carry both homozygous dominant and homozygous recessive Alleles
The alleles will influence other genes.
Answers
Answer:
Heterozygous alleles are called silent carriers of a trait because they carry two different alleles for a particular gene, but only one allele is expressed in the phenotype, while the other remains "silent." The expressed allele is usually dominant, while the silent allele is usually recessive. This means that the individual carrying the heterozygous allele will not show the recessive trait, but they can still pass it on to their offspring.
If two heterozygous parents each pass on a recessive allele, their offspring has a 25% chance of inheriting two recessive alleles and showing a recessive phenotype. In this case, the heterozygous parents are carriers of the recessive trait, but do not show it in their phenotype.
Therefore, the correct answer is: If two heterozygous parents each pass on a recessive allele their offspring will show a recessive phenotype.

The metric system is a system of measurement that is utilized throughout the world. The fundamental units of the metric system are meter, gram, and liter. In this system, prefixes are used to represent measurements that are bigger or smaller than the fundamental units.
The prefix “kilo-,” for example, indicates a measurement that is a thousand times bigger than the fundamental unit. Lab Intro - The Metric System Exercise A - Measurement or Distance The metric system is used to measure length or distance.
The standard unit of length in the metric system is the meter, which is represented by the symbol “m.” The metric system is used to measure distances or lengths that vary from millimeters (mm) to kilometers (km).In order to determine measurements in the metric system, the fundamental units are combined with prefixes.
For example, one centimeter (cm) is equal to 1/100th of a meter, while one millimeter (mm) is equal to 1/1000th of a meter. One kilometer (km), on the other hand, is equal to a thousand meters (m).

92ml 3.0 fl oz what is the ratio
Answers
The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).
1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).
Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).
Now we can express the ratio between 92 mL and 88.72 mL:
92 mL : 88.72 mL
Simplifying the ratio by dividing both sides by the greatest common divisor, we get:
46 : 44
So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

Look at the incomplete equation below. What does Ek represent?
Answers
In the given equation, Ek represents the kinetic energy of an object.
Kinetic energy (Ek) is a form of energy associated with the motion of an object. It is dependent on both the mass (m) and the velocity (v) of the object.
The equation Ek = (1/2)m\(v^2\) represents the formula to calculate the kinetic energy of an object.
The symbol "Ek" is commonly used to represent kinetic energy in scientific calculations and equations. By plugging in the values of mass and velocity into the equation, one can calculate the amount of kinetic energy possessed by the object.
The kinetic energy of an object increases with both its mass and velocity. As the mass increases, the object has more particles in motion, contributing to higher kinetic energy.
Similarly, as the velocity increases, the speed at which the object moves also increases, resulting in greater kinetic energy.
Therefore, understanding and calculating kinetic energy is important in various scientific and engineering applications, such as studying the movement of objects, analyzing collisions, or designing efficient systems.

Why do teens tend to make riskier decisions than adults?
Answers
Brain Development: The brain undergoes extensive development and reorganization during adolescence, particularly in the prefrontal cortex, which is responsible for decision-making, impulse control, and weighing consequences. This region develops at a slower pace compared to the reward-seeking regions of the brain, such as the limbic system. As a result, teenagers may be more driven by immediate rewards and less inclined to consider long-term consequences.
Sensation Seeking: Adolescence is characterized by heightened sensation seeking and a desire for novel and exciting experiences. Teenagers often seek out new sensations and engage in risk-taking behaviors as a way to explore their own identity, gain independence, and test boundaries. The pursuit of thrills and excitement can overshadow the potential risks involved.
Social Influence: Peer influence plays a significant role during adolescence. Teenagers are highly attuned to social acceptance and approval, and they may engage in riskier behaviors to fit in, gain peer recognition, or conform to social norms within their peer group. The desire for social status and acceptance can override concerns about potential negative outcomes.
Incomplete Experience and Judgment: Compared to adults, teenagers have less life experience and exposure to various situations, making it more challenging for them to accurately assess risks and make informed decisions. They may lack the cognitive tools and judgment skills to fully evaluate the potential consequences of their actions.
Emotional Intensity: Adolescence is a time of heightened emotional intensity, with teenagers experiencing intense emotions and seeking ways to regulate them. Risk-taking behaviors can serve as a means to cope with or regulate these emotions, providing temporary excitement, distraction, or a sense of control

produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answers
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.
It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

Plants take up carbon dioxide (CO2) during photosynthesis and release it during respiration. According to the article, how might increasing global temperatures affect the amount of carbon dioxide plants release during respiration?
Answers
Additionally, higher temperatures can also have a negative impact on plant growth and development, which can further increase the amount of carbon dioxide released during respiration. For example, if plants are exposed to prolonged periods of high temperatures, they may become stressed and allocate more resources to respiration instead of growth, which can result in increased carbon dioxide emissions.
Overall, increasing global temperatures are likely to have complex and potentially negative impacts on plant growth, respiration, and carbon dioxide emissions.

The crossing of F1 components generated offspring for the F2 generation, three of which were yellow (VV, Vv and Vv) and one was green (vv).
According to the factors that determine the color of the generated individuals, it is possible to state that
a) The yellow color is dominant and the green color is recessive.
b) The yellow color is recessive and the green color is dominant.
c) The color of the factors is determined by heredity in one of the genes.
d) One color is expressed at the expense of the inactivity of the other.

Correct alternative: a) The yellow color is dominant and the green color is recessive.
As observed in his experiment, Mendel identified that two factors determine the color of peas: a dominant for the yellow color and a recessive that expressed the green.
The dominant gene is the one that determines a characteristic, even when in simple doses in the genotypes. The recessive gene is only expressed when in double dose, because in the presence of a dominant, it becomes inactive.
