Sheila weighs 60 kg and is riding a bike. Her momentum on the bike is 340 kg • m/s. The bike hits a rock, which stops it completely and throws Sheila forward onto the pavement. If there is no net force on the system, what is Sheila’s velocity immediately after she is thrown from the bike?
Answer:
5.7 m/s
Explanation:
The computation of Sheila 's velocity right after she gets thrown out of the bike is shown below:
1) The Physical principle: conservation of momentum.
If there is no net external force operating on a system, so the system's total momentum is conserved
The momentum, p, is a vector magnitude that is determined as the product of the mass by the velocity:
P = mv.
2) Taking into account therefore that there is no net force on the device, Sheila and the momentum of the bike are the identical pre and post collision.
Based on this, the calculation is as follows
Momentum before the collision:
\(P_1 = (mass\ of\ Sheila + mass\ of\ the\ bike) \times velocity\)
\(P_1 = (60kg + m) \times v_1\)
= 340 kg m/s
Now Momentum after the collision:
\(P_2 = mass\ of\ sheila \times velocity\ of\ Sheila + mass\ of\ the\ bike \times velocity\ of\ the\ bike\)
\(P_2 = 60kg \times v_2 + m \times 0 = 60kg \times v_2\)
\(P_1 = P_2\)
\(= (60kg + m) \times v_1\)
\(= 60kg \times v_2\)
\(= 340 kg .\ m/s\)
\(= 60kg \times v_2\)
\(v_2 = \frac{340\ kg .\ m/s }{60\ kg}\)
= 5.7 m/s
The velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.
The given parameters;
mass of Sheila, m = 60 kgmomentum of Sheila, P = 340 kg.m/sThe velocity of Sheila immediately after she is thrown from the bike is calculated as follows;
P = mv
where;
v is the velocity Sheila
\(v = \frac{P}{m} \\\\v = \frac{340}{60} \\\\v = 5.67 \ m/s\)
Thus, the velocity of Sheila immediately after she is thrown from the bike is 5.67 m/s.

what structure in the membrane causes plasma membranes to resist freezing?
The structure in the membrane that causes plasma membranes to resist freezing is the presence of phospholipids with unsaturated fatty acid tails.
Unsaturated fatty acids contain double bonds between carbon atoms, which introduce kinks in the fatty acid tails.
These kinks prevent the fatty acid chains from packing tightly together, increasing the fluidity of the membrane.
As a result, the membrane remains flexible even at lower temperatures, reducing the likelihood of freezing. In contrast, membranes with saturated fatty acid tails lack these kinks and tend to be more rigid, making them more susceptible to freezing at lower temperatures.

Imagine a population evolving by genetic drift in which the frequency of allele k is 0. 2. What is the probability that at some point in the future allele k will drift to a frequency of 1?.
It is important to note that genetic drift is a random process, so it is not possible to accurately predict when or if allele k will reach a frequency of 1 in the future.
Genetic drift refers to the random fluctuations in the frequency of genetic variants or alleles within a population over time. It is one of the mechanisms of evolution and can have significant effects on the genetic composition of a population, particularly in small or isolated populations.
Key points about genetic drift include:
Random Nature: Genetic drift is driven by chance events rather than natural selection. It occurs when the frequency of alleles changes due to random sampling during reproduction. This random sampling can lead to the loss or fixation of alleles in a population.
More Pronounced in Small Populations: Genetic drift is more pronounced in small populations because chance events can have a greater impact on allele frequencies. In larger populations, the effects of genetic drift are typically less significant.
Founder Effect: The founder effect is a type of genetic drift that occurs when a small group of individuals establishes a new population in a different geographic area or becomes isolated from the larger population. The resulting population is likely to have reduced genetic diversity compared to the original population.
In a population evolving by genetic drift, the probability of an allele reaching a frequency of 1 depends on the population size and the initial frequency of the allele.
However, it is important to note that genetic drift is a random process, so it is not possible to accurately predict when or if allele k will reach a frequency of 1 in the future.

Visual accommodation contracts which extraocular eye muscle in the right eye? (do not use spaces
The extraocular eye muscle responsible for visual accommodation in the right eye is the ciliary muscle.
Visual accommodation is the process by which the eye adjusts its focus to see objects at different distances clearly. It involves the changing shape of the lens to bend light rays and focus them onto the retina. The primary muscle responsible for visual accommodation is the ciliary muscle. The ciliary muscle is located within the eye, specifically in the ciliary body, which is a ring-shaped structure behind the iris. When the ciliary muscle contracts, it causes the lens to become thicker and more curved, allowing it to focus on nearby objects. This process is known as accommodation. Conversely, when the ciliary muscle relaxes, the lens becomes thinner and less curved, enabling clear vision for objects in the distance. In the right eye, the ciliary muscle contracts or relaxes to adjust the lens for near or far vision, respectively, facilitating visual accommodation.

for each of the following organisms, describe how digested food reaches their body cells: a hibiscus plant, a paramesium, a coral polyp, an earthworm, a mosquito a human
Answer:
Hibiscus plant: transported by the phloem
Paramecium: simple diffusion from the food vacuole into the cytoplasm
Coral polyp: diffusion from the gut to the body cells
Earthworm: transport through the blood
Mosquito: transport through the blood
Humans: transport through the blood
Explanation:
Digestion involves both mechanical and chemical processes to break up
food into smaller or simpler constituent parts that can be absorbed by the body.
Digestion is divided into external digestion and internal digestion.
External digestion involves digestion of food outside the body using digestion enzymes and then absorption into the body by diffusion.
Internal digestion is when food is ingested into the body, broken down by Digestive enzymes and juices and then absorbed into the body cells.
A hibiscus plant stores it's food as starch. When the stored food is needed, it hydrolyses starch into molecules small enough to pass through the cell membrane. The hydrolysed food molecules are then transported by the phloem to cells that need them for energy production.
A paramecium is a protist which feeds by endocytosis, i.e. sorrounding and digesting food in its food vacuole. The digested food diffuses through the cell
cytoplasm and mitochondria oxidise it to produce ATP.
A coral polyp is a marine invertebrate belonging to the phylum Cnidaria.
Cnidarians have a simple sac-like gut, with only one opening and one unspecialised gut chamber.
They do not have a circulatory system to deliver nutrients to the cells, instead digested food diffuses from the gut to the body cells.
An earthworm is an annelid and carries out internal digestion. Food taken in from the mouth is digested and absorbed by the intestines into the blood. The blood then carries the absorbed food to the earthworm’s body cells.
Mosquitoes both male and female feed on sap and nectar, aphid honeydew, and plant juices, but in many species the mouthparts of the females are adapted for feeding on the blood of other organisms.
Food taken in by the mosquito is digested in the mid-gut by digestive enzymes. The blood absorbs digested food from the mid- gut and carries it to its body cells.
In Humans, digested food molecules are absorbed in the small intestine into our bloodstream. The blood then carried digested food molecules around the body to the cells where they are needed.

Mitosis and meiosis are two similar biological processes with important differences. They both start with a diploid cell, but end up with very different products. What is the final product for each process?
Answer:
The final products of mitosis and meiosis are different. Mitosis results in the production of two identical diploid daughter cells, each containing the same number of chromosomes as the parent cell. In contrast, meiosis produces four genetically diverse haploid daughter cells, each containing half the number of chromosomes as the parent cell. The purpose of mitosis is to ensure the growth, development, and repair of tissues in multicellular organisms, while meiosis is necessary for sexual reproduction, which involves the fusion of two haploid gametes (sperm and egg) to form a diploid zygote.
Explanation:
Mitosis is the process by which a cell divides and creates two identical daughter cells. It's like when you cut a piece of cake in half and each piece is the same size and has the same kind of cake. In mitosis, the parent cell starts with two sets of chromosomes (one set from each parent) and ends up with two daughter cells, each with the same two sets of chromosomes.
Meiosis is also a process of cell division, but it creates four different daughter cells, each with only one set of chromosomes (instead of the two sets found in most cells). This is like if you have a basket with pairs of socks, and you randomly take one sock from each pair and put it into four different baskets. Each basket has a different assortment of socks, and none of them have the exact same pairs as the original basket. In meiosis, the parent cell starts with two sets of chromosomes and ends up with four daughter cells, each with one set of chromosomes. This is important for sexual reproduction, because each parent contributes one set of chromosomes to their offspring, creating unique combinations of genetic information.

what is observation learning psychology
Answer:
Observational learning, also known as social learning or modeling, is a type of learning that occurs through observing and imitating the behavior of others. In psychology, observational learning is considered a form of social learning theory, which emphasizes the importance of the environment and social interactions in shaping behavior.
Observational learning can occur through direct observation of a model or through indirect observation, such as watching a video or reading about a behavior. The behavior that is observed and learned may be a new behavior, a modification of an existing behavior, or a reinforcement of an already learned behavior.
According to observational learning theory, there are four key elements that are necessary for observational learning to occur: attention, retention, motor reproduction, and reinforcement. Attention refers to the learner's ability to focus on the model's behavior, while retention involves the learner's ability to remember the behavior. Motor reproduction refers to the learner's ability to physically replicate the behavior, and reinforcement refers to the consequences of the behavior, which can either encourage or discourage future repetition of the behavior.
Observational learning has been shown to be a powerful tool for behavior modification and can be used in a variety of settings, such as in schools, workplaces, and therapy. It can also be used to explain how individuals acquire certain behaviors, such as aggression or altruism, and how cultural norms and values are transmitted from one generation to another.

The data show the age and location of rocks on the sea floor.
Distance from mid ocean ridge, 10 kilometers, age, 300,000 years. Distance, 25 kilometers, age, 1 million. Distance, 40 kilometers, age 1 million 625,000 years.
Describe the relationship between the age of the rocks and their distance from the mid-ocean ridge.
Determine whether the rate of plate movement is a slow or fast process.
Based on the given data, there is a clear relationship between the age of the rocks and their distance from the mid-ocean ridge.
What is the relationship between the age of rocks and their distance and is the rate of movement slow or fast?The rocks closer to the mid-ocean ridge are younger than the rocks farther away from it. Specifically, the rocks that are 10 kilometers from the ridge are 300,000 years old, while the rocks that are 25 kilometers away are 1 million years old, and the rocks that are 40 kilometers away are 1,625,000 years old.
This pattern of younger rocks closer to the mid-ocean ridge and older rocks farther away is consistent with the theory of plate tectonics.
The rate of plate movement can be estimated by dividing the distance between two points on the sea floor by the difference in their ages. Based on the given data, the rate of plate movement between the 10-kilometer and 25-kilometer marks is (25 km - 10 km) / (1 million years - 300,000 years) = 15 km / 700,000 years ≈ 0.021 km/year. Similarly, the rate of plate movement between the 25-kilometer and 40-kilometer marks is (40 km - 25 km) / (1,625,000 years - 1 million years) = 15 km / 625,000 years ≈ 0.024 km/year.
