Which of the following contains thousands of nuclei in a single "supercell?"
a.Plasmodial slime mold
b."The plasmodial slime mold Physarum polycephalum (featured in the end-of-chapter
Answer:
The correct answer is option a. "Plasmodial slime mold".
Explanation:
Plasmodial slime molds, are comprised of a single "supercell" with thousands or millions of nuclei within it. These organisms are formed by the fusion of multiple flagellated cells. The formation of these single celled organisms depend on the presence of enough food source. Typically, plasmodial slime molds have a diameter of 3 to 4 centimeters, but they can growth up to 30 centimeters.

PLS HELP!!! What best describes the relationship between
P. caudatum and P. aurelia in Graph B?
Predation
Mutualism
Interspecific competition
Intraspecific competition
Answer:
Interspecific competition
Explanation:
Interspecific competition occurs when two different species occupy the same environment as they coexist and depend on the same limited resources for survival. As a result of these limited resources, there's competition between the different species with each species having their different levels of fitness. Their level of fitness determines how well they will complete with other species. This will also determine if they will go extinct or thrive in such environment where there's interspecific competition.
The graph given shows the growth of the relative population size of two different species grown together.
It shows that P. aurelia, with time, outcompetes P. coudatum.
This graph clearly suggest that interspecific competition has occurred. Both species are competing for the same limited resources.
P. aurelia has a greater fitness which enables it to outcompete the other species sharing the same environment with it.
Interspecific competition beats describes the relationship between the two species in graph B.

what effect does insulin have on the body
Answer:
Insulin is a hormone made by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).
Answer:
The liver converts any excess glucose in the body that reaches it after a meal to glycogen. This process is stimulated by the hormone insulin which is secreted by the pancreas. Thank you for the question

The Vmax of the isoform of glycogen phosphorylase expressed in muscles is significantly larger than the isoform of the enzyme expressed in the liver enzyme. Explain the functional significance of this observation.
Answer and Explanation: In enzyme kinetics, one constant describing enzyme activity is Maximal Velocity (Vmax). It indicates how fast an enzyme can catalyze the reaction. It is dependent on substrate concentration.
As the muscle is an organ which needs a great amount of energy, the enzyme glycogen phosphorilase is very active on the organ, compared to the liver, where glicose is stored. So, the Vmax of glycogen phosphorylase expressed in muscle is faster than when expressed in the liver, means the enzyme in muscle has a bigger concentration of substrate and therefore will reach Vmax faster, i.e. will be significantly larger.

What is an example of how organic molecules play a role in the structure and function of different cell types
Answer:
For example, the sugars can be linked to form polysaccharides such as starch and glycogen, the amino acids can be linked to form proteins, the nucleotides can be linked to form the DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) of chromosomes, and the fatty acids can be linked to form the lipids of all cell
Explanation:
Organic molecules play a significant role in the structure and function of different cell types. For example, nucleic acid looks after the construction of genetic material among living organisms.
What are organic molecules?Organic molecules may be defined as all sorts of those molecules that primarily consist of carbon and hydrogen. It also includes other elements like oxygen, nitrogen, phosphorus, etc. Organic molecules must possess carbon atoms covalently bonded to hydrogen atoms (C-H bonds).
Among organic molecules, carbohydrates are the energy-deriving components that all cells require in order to perform their own cellular and metabolic activity.
Proteins are required for the structural arrangement and specific function of each cell type. It also functions as a hormone or enzyme. Lipids also store the energy needed for the body.

Which statement describes prey? They provide energy for dead organisms. They are killed by predators for energy. They obtain energy from dead organisms. They obtain energy from predators.
Answer:
the answer is B
Explanation:
The statement that describes prey is they are killed by predators for energy. The correct option is b.
What are prey and predator?Predators are often carnivorous creatures that hunt smaller animals for food. Predators hunt, capture, and eat the animals that make up their prey. When there are more predators in a particular environment, there will be less prey overall.
Predators lose population when they move to new locations in search of food, which increases the population of prey in the area from which they migrated. In other words, a cycle of events starting with a decrease in prey and ending with an increase in prey results from an increase in predators.
Therefore, the correct option is b, They are killed by predators for energy regarding the statement that describes prey.

Which age structure diagram shows that the number of individuals decreases
steadily with age?
Slow Growth
Negative Growth
Stable Growth
Rapid Growth
Answer:
Slow Growth
Explanation:
The age structure diagram is a method of understanding the population. It is used by the demographers to estimate the growth, fall, or change in the population of an area. The data required is the distribution of the age and the sex of an area. When the diagram is constructed and made into a pyramidal shape, it represents that there is a rise in the population of the area. a stable population can be estimated by there is straight up and down. The rapid growth model represents a rapid decrease in the population with age. The slow growth model represents a steady decrease in the population with age
