(T/F) Most cells reach a certain size, stop growing, and then divide.
Answer:
True
Explanation:
Most of the cells in the body of an organism reach a certain size, stop growing after a certain size, and then undergo division. Cells maintain the cell number in body through continuous division. Thus, the given statement is true.
What are Cells?Cells are the basic unit of life. Cells are the building blocks of living organisms. The human body is composed of cells. These cells provide the structure for the body, take in nutrients from food, convert the nutrients into usable form of energy, and carry out specialized functions such as digestion, respiration, excretion, and circulation, etc.
Specialized cells in the body of an organism have a certain size and shape and these undergo growth and division. Cells undergo cell cycle which consists of different phases such as interphase and M-phase where the cell grows in size and shape and divides to form more cells and thus maintain their number.

An animal cell lacking oligosaccharides on the external surface of its plasma membrane would likely be impaired in which function ?
Answer:
This question lacks options, the options are:
A) transporting ions against an electrochemical gradient
B) cell-cell recognition
C) maintaining fluidity of the phospholipid bilayer
D) attaching to the cytoskeleton
E) establishing the diffusion barrier to charged molecules
The answer is B
Explanation:
Generally, oligosaccharides are short chains of polysaccharides/carbohydrates. They make up the structure of membranes including the plasma membrane. Oligosaccharides attached to the protein content of the cell membrane to form a substance called GLYCOPROTEIN. The attached oligosaccharides functions in the ability for a cell to recognize another cell.
According to this question, if an animal whose cell is lacking oligosaccharides on the external surface of its plasma membrane, the most likely impairment would be that of CELL-CELL recognition.
Oligosaccharides are a type of carbohydrates that contain the combination of a few monosaccharides. The are also found as part of the components of the membrane.
If an animal cell lacks this type of carbohydrates (oligosaccharides), the function impaired would be the cell-cell communication function.
Oligosaccharides performs various functions as part of the component of the plasma membrane. It functions in cell to cell recognition and binding and communication. They usually contain 3-10 sugar units (monosaccharides).Learn more: https://brainly.com/question/22301340

According to the author, what is the main reason for the decrease in trillium in the forest? What evidence does she give to support her claim?
Answer:
The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium. The author cites a research study performed by scientists as evidence to support her claim. In this study, researchers planted two fields, each containing garlic mustard and trillium. One was left open to deer, and the other was fenced off. Scientists kept track of the fields for several years. They found that trillium was able to regain much of its original space in the protected field. In the unprotected field, there was still more garlic mustard because the deer ate the trillium. The author also states that similar research studies have been conducted in many forests across the United States, and they all reveal similar results.

Explanation:
The urinary system, sometimes referred to as the renal system, manages fluid and electrolyte balance as well as filters and eliminates waste items from the body.
How does the urinary system work?You must be reduced in size to pass through the filtration membrane and into the renal system on your voyage via the urinary system. The subclavian vein will be used as the injection site, and you must first pass through the heart to reach the arterial circulation. You have at least two minutes to unwind as you move through the systemic circulation before you arrive at the renal artery, which supplies the kidney.
Through the artery wall, you can make out the towering, brownish-red kidney. Once within, the kidney's blood arteries get progressively smaller until you reach the afferent arteriole, which feeds into the glomerulus, the filtering organ. Once inside the filter, you position yourself such that you are facing a pore directly. You are quickly carried across the filtration membrane and into the Bowman's capsule region of the nephron. You lower the specimen cup as you proceed to collect your first test sample of filtrate.
You examine the reading from the sample and discover that, with one exception, its chemical makeup is very identical to that of blood. Practically no blood cells exist. You can wait to take your next sample until you get to the Henle loop, or the "hairpin" in correct language. You observe the tubule cells as you proceed along your path because they have numerous thick fingerlike projections that protrude into the tubule lumen from their surface.
This portion of the tubule is relatively small, therefore these microvilli improve the absorptive surface area. You gather your second sample while in the "hairpin". The readout confirms that the filtrate's content is significantly lower and that few nutrients, including glucose and amino acids, are present.
Here, metabolic wastes are substantially more concentrated, and the area is yellow, which denotes the presence of the urochrome pigment. You know you have arrived in the distal convoluted tubule and are seeing the process of secretion when you gradually work your way up from the 'hairpin' and enter into an area where big molecules are being transported into the filtrate.
As you proceed, you notice that the streams are now more agitated and the water level has plummeted. You recall the function of the hormone ADH and assume that the body must have secreted it to save water. You make a sharp right and then plunge straight down into a tube that is being filled with fluid and other tubes. You become aware that you are moving towards the minor calyx in the collecting duct.
You move very calmly into a tube on the other coast after entering a much calmer area. You become aware that you are experiencing a rhythmic downward squeeze as soon as you enter this tube, indicating that you are in the ureter. You know you have arrived to the urinary bladder when you suddenly drop and splash into a sizable sea of urine. As you can see, there is a lot of fluid as the ceiling gets closer to you and the walls start to pull. Suddenly, you are propelled out of the body and into your host's urethra to leave the body.
Therefore, the urinary system, sometimes referred to as the renal system, manages fluid and electrolyte balance as well as filters and eliminates waste items from the body.
