What must be true about the number of chromosomes in each sex cell (when compared to the number of chromosomes in body cells
Answer:
The number of chromosomes in sex cell must be haploid (1n) as compared to body cell which is diploid(2n).
Explanation:
Body cells are diploid while the sex cells are haploid. We can say that sex cells contain half number of chromosomes as compared to body cells.
The number of chromosomes in each s-ex cell is half the number chromosomes in body cells.
Chromosomes:Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23. Of the 23 pairs, 22 are known as autosomes. The 23rd pair is made up of the s-ex- chromosomes, called the ‘X’ and ‘Y’ chromosome. These 46 chromosomes carry the g-enetic information that’s passed from parent to child through heredity.

why is this technique Punnett squares used to calculate the probability of genotypes and phenotypes of one child. In other words, why is it inappropriate to say "Two out of four of their children will have brown hair?
I don’t understand this help meeee
Answer:
A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes. A Punnett square can be used to determine a missing genotype based on the other genotypes involved in a cross. It is inappropriate to say "Two out of four of their children will have brown hair because the genes could are not always going to give you what you think you are going to get. Using punnett squares just predicts the outcome, but doesn't necessarily know 100%

Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practical to perform a Punnett square analysis on all possible combinations of all members of a population to predict what the population might look like in the future.
a. True
b. False
Answer:
True
Explanation:
There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing random distribution of the two traits. This random distribution cannot be captured through punnet square.
The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.
Compare Suspect 1 (S1) and Suspect 2 (S2) to the DNA evidence sample (E). Based upon the DNA fingerprints, which suspect was likely at the crime scene and why
Hello. Your question is incomplete and more information would be needed so that it could be answered accurately. However, I will try to help you in the best possible way.
As we know, fingerprints are formed by a unique pattern of lines that are not repeated between individuals. Thus, in order to discover who is a criminal, through the analysis of fingerprints, it is important to identify the pattern of lines left at the scene of the crime and analyze it with the pattern of lines in the suspect's fingerprint.
In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and returns to the liver. In the liver, lactate is converted back into glucose by gluconeogenesis. For each given enzyme, identify whether it is involved in the glycolysis pathyway, gluconeogenesis pathway, both pathways, or neither pathway.

2. b. gluconeogenesis
3. d. neither
4. b. gluconeogenesis
5. a. glycolysis
6. c. both
7. a. glycolysis
8. d. neither
Explanation:
Gluconeogenesis is the formation or synthesis of glucose while glycolysis is the conversion of glucose into pyruvate. Gluconeogenesis requires an enzyme for a non-reversal reaction which is not required in glycolysis.
Glyceraldehyde 3-phosphate dehydrogenase is an enzyme present in glycolysis that converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. It is a reversible reaction, this enzyme also present during gluconeogenesis converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate.
Glucose 6-phosphate to glucose during gluconeogenesis by glucose-6-phosphatase. Alcohol dehydrogenase is used for the conversion of ethanol into acetaldehyde and neither present in glyconeogenesis nor glycolysis. Oxaloacetate converts to phosphoenol pyruvate during gluconeogenesis by Phosphoenol pyruvate carboxykinase.
Fructose 6-phosphate changes into fructose 1,6-bisphosphate by Phosphofructokinase-1 during glycolysis.
Phosphoglycerate mutase is present in both pathways during glycolysis and during gluconeogenesis. This enzyme converts 3-phosphoglycerate to 2-phosphoglycerate and also converts 2-phosphoglycerate to 3-phosphoglycerate in glycolysis and gluconeogenesis respectively.
Hexokinase converts glucose to glucose 6-phosphate during glycolysis. However, Pyruvate dehydrogenase neither present in glycolysis nor gluconeogenesis.
Monosaccharides are the monomer of which organic
compound?
Monosaccharides are the monomer of organic compounds called polysaccharides (carbohydrate).
WHAT ARE MONOSACCHARIDES:
Monosaccharides are simple compounds that contain one unit of sugar (saccharide). They are monomeric units of larger organic compounds called POLYSACCHARIDES, which are complex carbohydrates. Monosaccharides cannot be further broken down as they are the simplest form of carbohydrate molecules. Examples of monosaccharides, also called simple sugars are glucose, fructose, galactose etc. and they are monomers of polysaccharide molecules like starch, cellulose etc.Hence, monosaccharides are the monomer of organic compounds called polysaccharides (carbohydrate).

What three parts make up the modern cell theory
The environmental factors that are important depend on the habitat true or false
Answer:
True
Explanation:
Answer:
true
Explanation:
The statement "carrying capacity can vary depending on environmental conditions" is true. Carry capacity is defined as the maximum population size of a species that an environment can sustain indefinitely. It is also defined as the environment's maximal load of a species. Factors that impact on the carrying capacity of a species are the availability of food and water, raw materials to build shelter, the environment's ability to process waste products, as well as the species' ability to reproduce.

A student prepares a cell homogenate from spinach leaves. She performs a cell fractionation experiment to determine the shortest amount time of centrifugation at 2000xg that will yield the highest percentage of chloroplasts in the pellet fraction. She splits the spinach homogenate into 5 equal parts and centrifuges the parts at 2000xg for 0, 5, 10, 15 or 20 min. She then determines the proportion of chloroplasts in the supernatant and pellet fractions. The controlled variable(s) in the student's experiment is/are:_____.
a. proportion of chloroplasts in each fraction.
b. use of same plant homogenate throughout.
c. time of centrifugation in minutes.
d. g-force of centrifugation.
Answer:
b. use of same plant homogenate throughout.
Explanation:
In an experiment, the controlled variable, also called the CONSTANT is the variable that is kept the same throughout the course of the experiment in order not to influence the result or outcome of the experiment.
In this question, a student performs a cell fractionation experiment to determine the shortest amount time of centrifugation (manipulated variable) at 2000xg that will yield the highest percentage of chloroplasts (responding variable) in the pellet fraction. In this experiment, the variable being controlled is same spinach plant homogenate used throughout.
1. What effect does air pressure have on wind movement?
2. What happens to the density of air as it is heated?
3. It’s a hot, sunny morning in a coastal town in South Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer:
1. The lower the air pressure the faster the wind the higher the air pressure the slower the winds
2. When the heat of the air increases the density of the air decreases.
3. The air above the ocean will, therefore, be warmer and of low pressure than that over land which will be cooler and of relatively higher pressure. Winds will, therefore, blow seawards because winds blow from high to low-pressure systems.

However, tissue culture is derived from already differentiated cells. These cells are already determined and can only produce cell type of that plant from which they were derived.
Gene therapy is a method of using genetic material to treat or prevent certain diseases. A common method researchers have found to accomplish this is with vectors. Vectors are essentially vehicles designed to deliver therapeutic genetic material, such as functional genes, directly to cells. A vector-valued function, also called a vector function, is a mathematical function of one or more variables whose extent is a multidimensional vector or a set of infinite-dimensional vectors.
