i) Predict which of the liquids would cause the largest decrease in mass of a potato stick
PLS HELP ME I’ll GIVE YOU 15 POINTS OR BRAINIEST
Answers
Answer:
1.0 mole per dm3 sodium chloride solution
Explanation:
The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established.
Hence, the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.

Answers
Answer:
Meiosis I
Explanation:
The separation of homologues occurs during meiosis I. The Option A.
When does the separation of homologues occur during cell division?During meiosis I, the process of cell division specifically designed for the formation of gametes, the separation of homologous chromosomes occurs. Meiosis I consists of several phases including prophase I, metaphase I, anaphase I, and telophase I.
In prophase I, homologous chromosomes pair up and exchange genetic material through a process called crossing over. During metaphase I, the pairs of homologous chromosomes align at the center of the cell. Then, in anaphase I, the homologous chromosomes separate and move toward opposite poles of the cell.

Answer: Disruptive selection
Explanation:
Hoped my answer was right and it helped you!!! Best of luck :D
also heres this
Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.
Stabilizing selection (not to be confused with negative or purifying selection) is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value. ... This means that most common phenotype in the population is selected for and continues to dominate in future generations.
directional selection: a mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. disruptive selection: (or diversifying selection) a mode of natural selection in which extreme values for a trait are favored over intermediate values.

Answer:
Cell - the basic unit of life for all organisms
Tissue - a group of cells that are similar in structure and function
Organ - a group of tissues that work together to perform specific activities for an organism
Organ system - a group of organs that work together to perform specific activities for an organism
Organism - a living thing that carries out the processes of life
Explanation:
You haven't provided the list of levels of an organism's organization. This is the list:
CellTissueOrganOrgan systemOrganismThe cell is the smallest, basic unit of life of all organisms.
A large number of cells that are close to each other and work together make up a tissue (e.g. blood, muscles, nervous tissue). These cells don't have to be identical. For example, blood is a tissue that consists of a variety of cells. Every type of these cells has its own unique function.
Multiple types of tissue that work together and have a specific role make up an organ (e.g. liver, heart, lungs).
Organ systems are groups of organs that work together to perform a certain function in an organism's body (e.g. respiratory system, cardiovascular system, nervous system).
An organism is made up of multiple organ systems. It can be defined as a living thing that carries out processes of life.

b. most similar to the frog the skin cell came from
c. different from both frogs that the cells came from
d. identical to both frogs that the cells came from
Answers
Answer: most similar to the frog the skin cell came from
Explanation:
I just took the test
The tadpole produced by the cloning process will be genetically most similar to the frog the skin cell came from. Thus, the correct option for this question is B.
What is the Cloning process?The cloning process may be defined as a type of technique that scientists significantly use to construct exact genetic copies of living things. This process is used to create an exact genetic replica of another cell, tissue, or organism.
The copied material, which has the same genetic makeup as the original, is referred to as a clone. The skin cell of the frog is divided through the process of mitosis which produces cells that are genetically identical to the parental cell.
The process of meiosis is carried out by gamete cells or germ cells which produce daughter cells that are not genetically identical to the parental cell.
Therefore, the tadpole produced by the cloning process will be genetically most similar to the frog the skin cell came from. Thus, the correct option for this question is B.

lack of vegetables in diet
Answers
Answer:
Without veggies, you're more prone to digestive disorders such as constipation, hemorrhoids, and diverticulosis. Owy! Vegetables contain cellulose, which increases stool weight, eases passage, and reduces transit time.
Vegetables are edible part of the plant. It is largely consumed by different animals. These are highly rich portions of plants with starch. The difference between the fruit and vegetable is that fruit is ovary portion and other edible parts of plant are categorized as vegetables(roots, edible photosynthetic parts).
_____________________________________[tex]\huge\textbf{Nutrients}[/tex]Eating vegetables provides many health benefits to our body. It reduces the chances of chronic diseases. Chronic diseases are those disesases which are long lasting such as cancer, heart diseases, diabetes etc.
No Fats and Cholestrol The vegetables do not have animal fat and cholestrol which makes them great for consumption who have heart diseases or which are recommended to have low fats diet by the doctor. Cholestrol adds into the lump of LDL(low density lipoproteins) inside the blood vessels which cause the blockade of the vessel causing heart diseases. Vitamins Since the plants absorb nutrients and ions from the soil so they are really rich in Vitamins. Vitamin A, C and K are common in plants.Rich in Potassium and Magnesium They have potassium, magnesium, folic acid in large quantity and Dietary fibers. _____________________________________[tex]\huge\textbf{Benefits}[/tex]Potassium maintain blood pressure.The Vegetable Sources of potassium include sweet potatoes, white potatoes, white beans, tomato, beet greens, soybeans, lima beans, spinach, lentils, and kidney beans.
Dietary fiber helps reduce blood cholesterol levels and may lower risk of heart disease. Fiber is important for proper bowel function. It helps reduce constipation and diverticulosis. Fiber-containing foods such as vegetables help provide a feeling of fullness with fewer calories. Folate (folic acid) helps the body form red blood cells. In Pregnant women, this reduces the risk of neural tube defects, spina bifida, and anencephaly during fetal development. Vitamin A keeps eyes and skin healthy and helps to protect against infections. Vitamin C helps heal cuts and wounds and keeps teeth and gums healthy. Vitamin C aids in iron absorption._____________________________________[tex]\Large\textbf{Diseases caused by Desiciency of Vegetables}[/tex]
The deficiencies caused by the lack of vegetable in diet are listed as below,
Cardiovascular Diseases There is high risk of CVDs as patient would use Animal fats which are rich in cholestrolDigestive Problems The vegetables have dietary fibers thus help in Digestion, If there is no vegetables in the diet then person would suffer from constipation or irregular bowelCancer Evidence suggests that including fruits and vegetables in the diet reduces the risk of cancer. Berries contain anthocyanin, which has demonstrated an inhibitory effect in colon cancer.Vision Green leafy vegetables containing carotenoids, increase the eye’s visual performance Depression Numerous studies have found links between the consumption of fruit and vegetables and depression.Metabolic Disorder Metabolic syndrome is characterized by impaired blood glucose, elevated blood pressure, dyslipidemia, and abdominal obesity. A diet rich in fruits and vegetables is associated with a reduced risk of diabetes mellitus, hyperlipidemia, and hypertension.Scurvy It is caused by the deficiency of Vitamin C.Nyctalopia It is also known as Night Blindness, It is caused by the deficiency of Vitamin A.Haemophilia Caused by the deficiency of Vitamin K._____________________________________Best Regards,'Borz'please help , i’ll give brianliest
