The lymphatic capillaries reabsorb as much as 20% of the fluid lost by the blood capillaries. TRUE or FALSE
Answers
The lymphatic capillaries absorbs excess of tissue fluid which is formed by oozing out of fluids from blood capillaries. About 10% of the fluid lost is reabsorbed. So the statement is false.
Lymphatic capillaries are a part of lymphatic system. When blood flows though small blood capillaries, plasma is leaked out into the surrounding tissues and becomes the part of tissue fluid. This tissue fluid helps in exchange of oxygen and nutrients to the cell and waste and carbon dioxide from the cells.
When there is an increase in osmotic pressure of tissue fluid, it is reabsorbed by lymphatic capillaries and is returned to the blood stream. Unlike blood capillaries, lymphatic capillaries allows transport only in one direction, to the vessels. This carries the fluid back to the blood stream. This transport is facilitated by the contraction of muscles. So as there is no pumping or an external force acting on this flow, it is slow.
About 10% of the fluid is reabsorbed by the lymphatic capillaries.

The statements that is not true about stage 3 of the birthing process is that there C. Intense contractions occur.
What is the birthing process?It involves four stages of labor: the cervix shrinking and opening during the first stage, the baby's descent and birth during the second, the placenta being delivered during the third, and the mother and child recovering during the fourth stage, known as the postpartum.
let's quickly review the three stages of labor. True labor contractions begin the first stage, which concludes when the cervix is fully effaced and dilated. The baby is born at the conclusion of the second stage, which is the pushing period. The placenta is delivered to complete the third stage.
Therefore, option C is correct.

When the concentration of water is the same on both sides of a membrane there is no net movement. This is shown on a graph where the trendline crosses the x-axis. What is this point called?
Answers
Answer
The point where the concentration on both sides of a membrane is equal to each other is called the Isotonic Point.
Explanation:
The result is that osmosis cannot or stops to occur. For net water movement to occur, the solution on one side of the membrane needs to have a higher concentration than the other.
isotonicity can also occur between two membranes when due to the process of Osmosis, the concentration on both sides of of the membrane have equalised.
Cheers!
The point where the concentration of water molecules is the same on both sides of a membrane and therefore there is no net movement is called ISOTONIC POINT.
An isotonic solution is a solution where solute concentration across a semipermeable membrane is the same, thereby there is no net flow of water (H2O) molecules. In consequence, if a cell is placed in an isotonic solution, the cell's volume will remain stable (i.e., the cell is in Osmotic Equilibrium).A hypertonic solution is a solution where there is a greater concentration of solute molecules outside the cell than inside the cell. If a cell is placed in a hypertonic solution, H2O molecules will out the cell and therefore this cell will shrink. A hypotonic solution is a solution where there is a lower concentration of solute molecules outside the cell than inside the cell. If a cell is placed in a hypotonic solution, H2O molecules will enter the cell, and therefore this cell will swell.In conclusion, the point where the concentration of H2O molecules is the same on both sides of a biological membrane is called the ISOTONIC POINT.

Answers
In the chart, a dihybrid cross between pea plants is shown. The genotypes of the parents in the given cross are supposed to be RRYY and rryy. Thus, the correct option for this question is C.
What is a Dihybrid cross?A dihybrid cross may be defined as a type of cross that occurs between two individuals with two observed traits that are controlled by two distinct genes. In this mating experiment, two organisms are identically hybrid for two traits.
According to the context of this question, the genotypes of parents are RRYY and rryy. This cross produces all offspring with the genotype RrYy. The F1 generation is further selfed in order to produce the organisms in the phenotypic 9:3:3:1 ratio. In this, 9 are round yellow, 3 are round green, 3 are wrinkled yellow, and 1 is wrinkled green.
Therefore, the genotypes of the parents in the given cross are supposed to be RRYY and rryy. Thus, the correct option for this question is C.

In his trips to the Galapagos Islands, Charles Darwin observed that 4 of the 13 species of the islands' finches have beaks adapted to eating specific foods. Which of the following best explains how these adaptations came to be?
A.) The finches were different species but resemble each other because of how they evolved in a similar environment.
B.) The finches descended from a common ancestor but evolved differently in response to their environment.
C.) The finches descended from the same ancestor but evolved along their own lines in isolation from each other.
D.) The finches descended from similar ancestors and have evolved adaptations in response to each other's influences.
Answers
B is the best response to this query. Despite sharing a similar progenitor, the finches have developed in distinct ways depending on their environments.
This is a result of the Galapagos Islands' isolation from the rest of the world and the generations-long isolation of the island's resident finches. Since they can adapt to their surroundings in different ways and have diverse beak shapes and sizes to eat on various sorts of food, finches have been able to evolve independently.
This phenomenon, known as adaptive radiation, explains why the Galapagos finches have developed distinctive beaks tailored for consuming particular foods.

What is the genotype?We know that the genotype has to do with the sum total of the genes that the organism has received from its parents. Now we know that there are some genes that could be expressed in more than a single format. Thus, we have a pair of genes that have been linked to a single trait. These pair of genes that have been linked a single trait is called an allele. The allele is important when we are considering the phenotype or the expressed traits of the organisms.

record the growth of the organisms over another ten-week period, this time in
water that averaged 25°C
Answers
After recording the growth of the organisms over another ten-week period, this time in water that averaged 25°C the temperature of the medium causes the growth graph to fluctuate up and down.
The line climbs upward due to the existence of the optimal temperature for the growth of that organism, which grows best in the temperature range of 15°C to 25°C.
The graph swings downward because the water temperature is unsuitable for the growth of that organism, which grows best in the temperature range of 5°C to 15°C.
We can infer that the growth rate changes owing to water temperature as the organism grows best in the 25°C to 35°C temperature range and the graph swings downward because the water temperature is not conducive to its growth.
