How does the central vacuole of a plant cell allow the plant to stand up right wilt?
Answer: Large centrally located vacuole is the characteristic feature of a plant cell. It is a single membrane bound sac like structure that provide structural support to the cell. It also controls turgor pressure. It stores water inside that keeps the plant to stand still. When the plant is fully hydrated, the central vacuole is filled with water and the membrane of the vacuole pushes against the cell wall. this increases the turgor pressure inside the plant cell and the plant cell stands stiff in an upright position.

As DNA is replicated, which DNA base pair will bond to cytosine?
adenine
thymine
cytosine
guanine
Answer:
The correct answer would be guanine.
It can be explained with the help of base-pair complementary rule which states that adenine will always base-pair with thymine and guanine will always base-pair with cytosine.
Adenine bonds with thymine through two hydrogen bonds and guanine bonds with cytosine through three hydrogen bonds.
As DNA is replicated, the DNA base pair that will bond to cytosine is Guanine. More information about DNA replication is found below.
What is DNA replication?DNA replication is the process whereby DNA molecule is duplicated to form two identical copies.
DNA is made up of monomers called nucleotides. The four nucleotides are as follows:
AdenineGuanineCytosineThymineIn the DNA molecule, the following bonding of nucleotides applies:

Visual field changes: The nurse should inquire about or observe any peripheral vision loss, shadow-like curtain, or veil covering part of the visual field.
Blurred or distorted vision: The nurse should ask the client about any changes in vision clarity or distortion of straight lines or objects.
Reduced central vision: The nurse should assess for a sudden or gradual decrease in central vision acuity.
Pain or discomfort: The nurse should inquire about any eye pain, discomfort, or pressure, which may occur with retinal detachment, especially if associated with other visual symptoms.
Complete question:- The nurse is assessing a client with retinal detachment. The nurse should assess the client for which of the following signs and symptoms indicative of retinal detachment?

You are interested in purchasing a home. you can afford $1200 a month as a mortgage payment. how much can you pay for a home assuming a 30 year (360 months) loan at 4.25% interest? (please reference the loan information in the "task 2 data" cells as the arguments for your function.)
To determine how much you can afford for a home with a monthly mortgage payment of $1200, a 30-year loan, and 4.25% interest, you rearrange the mortgage payment formula to solve for the loan amount. After substituting the known values into the formula, we find that you can afford a home priced up to approximately $236,319.
Explanation:To calculate how much money you can pay for a home, you should use the mortgage payment formula, which is M = P [r (1 + r) ^n] / [(1 + r) ^n – 1]. In this case, M is your monthly mortgage payment, P is the loan amount, r is your monthly interest rate (yearly interest divided by 100 and then divided by 12), and n is your number of payments (years of loan times 12).
In your situation, M = $1200, r = 4.25% / 100 / 12 = 0.00354 approximately, and n = 30 * 12 = 360. We can rearrange the formula to solve for P: P = M [(1 + r) ^n – 1] / [r (1 + r) ^n], substitute the values into the formula, and get P = $236,319 approximately.

The gap between two communicating neurons is termed:
The gap between two communicating neurons is termed as the synaptic cleft. This gap acts as the communication link where the transmission of information occurs from one neuron to another
Explanation:The gap between two communicating neurons is termed as the synaptic cleft. In neuroscience, a neuron is a specialized type of cell which plays a vital role in the function of the nervous system to transmit information to different parts of the body. The synaptic cleft, also known as synaptic gap, acts as the communication link where the transmission of information occurs from one neuron to another using chemical messengers called neurotransmitters. It is by this process that signals from the brain are sent to different parts of our body, allowing us to respond to stimuli.

A researcher recorded eight different species of bumble bees in the grasslands of Arkansas. Each species is present in large numbers. Which reason most likely explains the diversity of bumble bees in the grasslands ?
The diversity of bumble bees in the grasslands of Arkansas is likely explained by the presence of different floral resources, suitable nesting sites, and the absence of major limiting factors.
Explanation:The diversity of bumble bees in the grasslands of Arkansas is likely explained by several factors. One possible reason is the presence of different floral resources in the grasslands. Bumble bees rely on flowers for food, and different species of bumble bees may have different preferences for specific types of flowers. The presence of a variety of floral resources can attract and support a diverse community of bumble bees.
Another factor that may contribute to the diversity of bumble bees in the grasslands is the presence of suitable nesting sites. Bumble bees require suitable locations to build their nests and raise their young. The grasslands may provide a range of nesting opportunities, such as underground burrows or abandoned rodent nests, which can support multiple species of bumble bees.
Lastly, the absence of major factors limiting bumble bee populations, such as pesticide use or habitat destruction, may also contribute to the high diversity of bumble bees in the grasslands. When bumble bees are not threatened by these negative influences, they have the opportunity to establish and maintain diverse populations.

Which muscle is not part of the rotator cuff?
The deltoid muscle, among others like the rhomboids and latissimus dorsi, are not part of the rotator cuff. The rotator cuff consists of the tendons of four specific muscles: the deep subscapularis, supraspinatus, infraspinatus, and teres minor.
Explanation:The rotator cuff is an important component of the shoulder joint formed by tendons of four muscles, specifically the deep subscapularis, supraspinatus, infraspinatus, and teres minor. These muscles arise from the scapula and attach to the humerus, providing essential structural support and allowing a range of movements. However, the deltoid muscle, which originates on the scapula, is not a part of the rotator cuff though it plays a significant role in the motion of the shoulder, facilitating actions such as flexing, medial rotation, extension, and lateral rotation of the arm.
Other muscles that are not part of the rotator cuff, but vital to the movement of the upper limb, include the rhomboids, trapezius, latissimus dorsi, brachioradialis, extensor carpi radialis, and extensor digitorum amongst others. While these muscles contribute to the flexibility and strength of the upper limb, they do not form the rotator cuff.

Write an analogy to explain why cell size is limited
Final answer:
Cell size is limited because as a cell grows, its surface area to volume ratio becomes less favorable for efficient diffusion of nutrients and waste, similar to transportation issues in an overly large city. Cells remain small or adapt by becoming flat to maintain efficient diffusion and cellular function.
Explanation:
An analogy that explains why cell size is limited can be thought of in terms of a city. If the city (cell) is too large, transportation (diffusion of nutrients and waste) becomes inefficient, and the central areas (the center of the cell) may not receive the necessary resources or be able to dispose of waste effectively. This inefficiency of resource travel limits the size of the city, just as it restricts the growth of a cell.
The limitations of cell size are primarily due to the surface area to volume ratio, which determines how effectively substances can enter and leave a cell. As a cell grows, its volume increases faster than its surface area, making it challenging to transport substances across the cell membrane efficiently. Therefore, cells have adapted to remain small or flat to maintain a sufficient surface area to volume ratio, allowing for efficient diffusion and cellular function.
Overall, to function optimally, cells must maintain a size that supports quick and effective diffusion of nutrients and waste. This is why most organisms, even very large ones, are made up of tiny cells instead of smaller ones.
