Answer:
C
Explanation:
Semi means partly
permeable means allowing liquids or gases to pass through it
Semipermeable means allowing some, but not all, liquids or gases to pass through it.
Answer:
c) It is a barrier with tiny openings that let some, but not all, materials pass through.
Explanation:
The prefix "semi-" means "some; partially". "Permeable" means "allow to pass through". Using your knowledge of the purpose of the membrane and the meaning of the word "semi-permeable", you would use context to come to the conclusion that the correct answer is c) It is a barrier with tiny openings that let some, but not all, materials pass through.
Which of the following is a possible consequence of solid pollutants in a lake or river?
Build-up of garbage in freshwater
Quick drop in dissolved oxygen
Decrease in algae colonies
Sudden hypoxic waters
Answer:
B.) Quick drop in dissolved oxygen
Explanation:
High level of total suspended solids will increase water temperatures and decrease dissolved oxygen levels. This occurs because the pollutants absorb more heat from solar radiation than water molecules.

Here is an image of the mitochondria. Mitochondria numbers can differ between cell types based on the function of the cell. Which of these cells would contain the highest number of mitochondria? A) skin cell B) lung cell C) muscle cell D) red blood cell.
The cell organelle that produces most of the energy for cell functioning and growth is mitochondria. Mitochondria is a double membrane organelle that varies in number in cells.
The highest number of mitochondria is found in:
Option C) Muscle cells
The function of mitochondria can be explained as:
Muscle cells and tissues are bodily organizations that constantly and frequently move so to provide energy for the actions the muscle cells have the highest number of mitochondria.The skin and lungs cells vary in mitochondrial quantity and may contain hundreds or thousands. Some amount of cell requires more amount of energy as compared to others so the number of mitochondria in those cells will be more.The blood cell of mammals lack mitochondria in their structure.Therefore, muscle cells have the highest number of mitochondria.

11 Apply If you have a cold that causes congestion in your sinuses, how
might that affect your sense of smell? Support your claim with evidence.
Answer:
If there's a blockage of this channel, like when you have a stuffy nose due to the flu or a cold, odors can't get to the sensory cells the smells stimulate. This results in you losing a lot of your ability to taste the flavor of food. In this manner, your senses of taste and smell work closely together.
Answer:
It will affect your smell because you can have a lot of snot in your nose and your nose will be stopped up with all that stuff.

The last woman scientist discovered one gene that is unique in human, and she called it an Eureka moment. How many letters are different in that gene if you compare the chimp version with the human version
Only one letter is different between the human gene and the chimpanzee gene.
What is a gene?
A gene is a term to refer to the molecular unit of genetic inheritance that is composed of deoxyribonucleic acid, that is,
A sugar group. A phosphate group. A nitrogenous base. Guanine (G) Cytokine (C) Thymine (T) Adenine (A)
Man and chimpanzee share 99% of their genes. However, there are important genetic differences for us to be a different species from chimpanzees. Well, the change of a single nitrogenous base and differentiates the gene of a chimpanzee from the gene of a human.

The suncoast tree of northwest Africa is known for 2 traits that are said to show simple dominance. The 2 traits are height and bark color. In height, tall is dominant to short, and in bark color blue is dominant to purple. What would the genotypes be of a suncoast tree that is pure bred purple and tall and a suncoast tree that is heterozygous for both traits?
A. bbTT X BbTt
B. BBtt X BBTT
C. bbtt X bbtt
D. BbTt X BbTt
The genotypes would be bbTT X BbTt
Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.
Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)
The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTTThe genotype of a tree that is heterozygous for both trait would be BbTtThus, the cross would be bbTT x BbTtMore on genotypes can be found here: https://brainly.com/question/20730322?referrer=searchResults

Please explain the health principles that are practiced by Rastafarians in Trinidad and Tobago and how this information prepares you as a nurse to better serve this community.
Answer:
Rastas, as members of the movement are called, see their past, present, and future in a distinct way. Drawing from Old Testament stories, especially that of Exodus, they “overstand” (rather than understand) people of African descent in the Americas and around the world to be “exiles in Babylon.” They believe that they are being tested by Jah (God) through slavery and the existence of economic injustice and racial “downpression” (rather than oppression). Looking to the New Testament book of Revelation, Rastas await their deliverance from captivity and their return to Zion, the symbolic name for Africa drawn from the biblical tradition. Ethiopia, the site of a dynastic power, is the ultimate home of all Africans and the seat of Jah, and repatriation is one goal of the movement. Many (though not all) Rastas believe that the Ethiopian emperor, His Imperial Majesty Haile Selassie I, crowned in 1930, is the Second Coming of Christ who returned to redeem all Black people. The movement takes its name from the emperor’s precoronation name, Ras Tafari.

The air we breathe is mostly a mixture of oxygen and nitrogen. How do air molecules change when they reach altitudes above 100 km?
I need to make sure the answer I have is right.
As you increase in altitude, there are fewer air molecules. Due to the lower amounts of air molecules, the atmospheric pressure decreases causing the air to be harder to breath in.
You are maintaining a small population of fruit flies in the laboratory by transferring the flies to a new culture bottle after each generation. After several generations, you notice that the viability of the flies has decreased greatly. Recognizing that small population size is likely to be linked to decreased viability, the best way to reverse this trend is to cross your flies with flies from another lab.

How does your body respond to a decrease in blood glucose
Answer:
When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal.
Explanation:
hope this helps!
MERRY CHRISTMAS AND HAPPY NEW 2022 YEAR! GOD BLESS YOU!!!
Answer:
Glucose is a sugar that comes from the foods we eat, and it's also formed and stored inside the body. It's the main source of energy for the cells of our body, and is carried to each cell through the bloodstream. Our brains depend on glucose to function, even when we're sleeping.
The blood glucose level is the amount of glucose in the blood. When these levels (also called blood sugar levels) drop too low, it's called hypoglycemia (pronounced: high-poe-gly-SEE-me-uh). Very low blood sugar levels can cause serious symptoms that need to be treated right away.
Low Blood Sugar Levels in Diabetes
People with diabetes can have low blood sugar levels because of the medicines they have to take to manage their diabetes. They may need a hormone called insulin or diabetes pills (or both) to help their bodies use the sugar in their blood.
These medicines help take the sugar out of the blood and get it into the body's cells, which makes the blood sugar level go down. But sometimes it's a tricky balancing act and blood sugar levels can get too low.
People with diabetes need to keep their blood sugars from getting too high or too low. Keeping blood sugar levels in a healthy range means balancing when and what they eat, and when they exercise with when they take medicines.
