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.

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 are Meristem cells?Meristem cells are totipotent meaning they can differentiate to any type of plant cells. Therefore they can produce a variety of plant type depending on epigenetic. 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.

List 3 ways that microwaves are beneficial to society
African elephants once existed in large populations across the African continent. Elephants use their tusks to dig for water and food. Humans hunt and kill elephants for their tusks. Habitat loss and fragmentation have also reduced the total number of elephants and the size of elephant herds. Scientists estimate that the number of African elephants has decreased from several million to several hundred thousand. Population sizes range from over 100,000 individuals in Botswana to approximately 100 individuals in northern Cameroon. Scientists have also found that the frequency of elephants that never develop tusks is increasing.
Select all the statements that describe probable effects of poaching and habitat fragmentation on clephant evolution
a. The elephant population in Botswana will experience high levels of genetic drift.
b. The poaching of elephants for their tusks is leading to the evolution of tuskless elephants.
c. Having tusks does not provide a selective advantage to African elephants.
d. Habitat fragmentation leads to decreases in population size and increases in genetic drift.
e. The elephant population in Cameroon will experience high levels of genetic drift.
Answer:
Option D
Explanation:
In habitat fragmentation, a large ecosystem or habitat of any species is converted into small ecosystems in such a way that each small ecosystem remains isolated from each other. Being isolated , random genetic drift comes in picture and reduces the gene flow with in the isolated habitats.
Hence, option D is correct
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.

Explanation:
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.

d. neither
Answer:
The correct answer is -
1. c. both
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.

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.

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.
