Relate cell size to cell functions, and explain why cell size is limited.
Answer:
Cells are small to have a larger surface area to volume ratio
Explanation:
Since there is always things moving across the phospholipid bilayer of the cell, there needs to be a large surface area compared to volume. A good analogy that I use is elephants ears. They are huge but super thin to keep a large surface area to volume ratio. This lets heat diffuse from the elephant. Its the same thing with cell, maximizing the efficiency of the phospholipid bilayer.

What are Pea plants?Pea plants are either tall or short, which is an easy trait to observe, with that being said pea plants grow quickly, so he could complete many experiments in a short period of time.One of the reasons why Gregor Mendel chose to study pea plants is because they reproduce sexually.
In Gregor Mendel's work on pea plants, he discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Parental genes are randomly separated to the reproductive cells so that s-ex cells contain only one gene of the pair.
Therefore, To study genetics, Mendel chose to work with pea plants because they have easily identifiable traits.

Please i need help fast! What societal, ecological, or technical constraints should resource managers consider before proposing solutions?
Answer:
Explanation:When the cumulative impact of humans was small, the environmental implications of ... Ecological constraints add one more set of considerations to the list. ... difficulty of finding short-term solutions that do not aggravate long-term problems. ... Rates of extraction of renewable resources should not exceed regeneration rates.
Answer and Explanation:
Social constraints refer to the social traits and behaviours that affect the project's sustainability within a public. Social constraints include informal norms comprising cultural preference or formal practices, for example, government rules, that a resource manager should consider before proposing a solution. Technical constraints are fixed technical design decisions that might not be altered. Most frequently, technical constraints are brought by the stakeholders at the onset of the plan. There are technical constraints that a resource manager should consider before proposing a solution such as programming language required for numerous reasons, platforms supported or operating system and frame work. Businesses are the most affected by ecological constraints. Ecological constraints such as social expectations and requirements, competitors' act, legal requirements, modification in business, and modification in technology that a resource manager should consider before proposing a solution. Ecological constraints are essential to the business that should be plan ahead.
Your friend Suzanne says that the Ancient Romans must have sent letters only when they were in love or wanted to wish their friends a happy birthday because that's what her family does. How would you describe Suzanne's behavior? Egotistic ethnocentric ethno-oriented scientifically tested
Answer:
ethnocentric
Explanation:
Based on this scenario, I would describe Suzanne's behavior as being ethnocentric. This is simply due to the fact that she is applying her own cultural customs to that of Ancient Romans which she has never met or dealt with their customs. She is simply using her own experiences from her culture and what she knows to explain other culture's behaviors, which is exactly what an ethnocentric person tends to do.

New York City was the first major city in the world to offer online water tracking, as part of the city’s shift to the equivalent of a smart grid for water.
Utility officials have traditionally read water meters manually, sometimes as infrequently as four times per year. Of course, sending out meter readers is expensive and inefficient. It also means water bills may be based on estimates and subject to human error.

A permeable. B. semi-permeable
C. impenetrable
Answer:
B, semi-permeable
Explanation:
Answer:
Semi-Permeable
Explanation:
This is due to the reason that cell membranes require water and other nutrients to enter the cell and waste to exit the cell in order for it to function properly. If the cell membrane were permeable, anything would be able to enter including harmful microbes. If the cell membrane were impenetrable, the cell would die as it would not be able to receive the nutrients and materials needs.

Answer:
Germ
Explanation:

The types of cells which are found n the reproductive organs of humans are known as germ cells.
Which types of cell divisions are performed by germ cells?The types of cell divisions that are performed by germ cells are known as meiosis and mitosis. Meiosis is a type of cell division through which produces four haploid daughter cells that are not identical to their parents.
Germ cells are responsible for the production of gametes. This involves the differentiation of germ cells in order to produce male and female gametes. These cells are sometimes known as immortal because they are thought be assemble a linkage between generations.
Somatic cells are those cells that are responsible for the building blocks of the entire body. These somatic cells are only divided by mitosis.
Therefore, germ cells are the types of cells that are found in the reproductive organs.
