Which organ system gives instructions to the muscular system and the circulatory system during exercise?
Answers
Answer:
Nervous system
Explanation:
The nervous system can be divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The autonomic nervous system is a part of the PNS which is concerned with the control of involuntary physiologic processes. During the exercise, the sympathetic nerves of the autonomic nervous system are in charge of preparing the body for physical activity by increasing the respiration rate, heart rate and blood pressure. The sympathetic nerves can also increase energy for the muscles by reducing insulin release and increasing blood glucose.

When a person undergoes gastric bypass surgery, can their hunger, appetite, and
satiety cues change?
Answers
Answer:
Yes
Explanation:
Yes, after an individual undergoes gastric bypass surgery many different metabolic hormones become affected by the surgery. Such hormones include Gherlin, Leptin, Gastrin, and Insulin, all of which can affect the individual's hunger, appetite, and satiety cues. This is mainly because the surgery greatly shrinks the amount of food that an individual can eat at any given time. Since it basically shrinks the stomach by creating a small pouch where food enters and goes straight into the intestinal track it gives the individual the feeling of being full with much less food.

12. Where is the rate of primary production the lowest?
a. upwelling along coasts
b. in the middle of the current gyres
c. along the Equator
d. around Antarctica in the summer
e. coasts
Answers
Answer:
Option B, in the middle of the current gyres
Explanation:
The zones of upwelling have high productivity as they have adequate climate and weather condition along with availability of nutrients. The same is applicable for Equator and coastal regions. The productivity of Antarctica is low but not less than that of current gyres as in the middle of the current gyres there are high current streams that reduces the biological productivity.
Hence, option B is correct

What is cell theory ?According to the cell theory,
Cells make up every living thing. They can be either unicellular or multicellular in nature.The simplest form of life is the cell.Existing cells give rise to new ones. They are not the result of spontaneous generation.Eukaryotes are thought to have developed from prokaryotes approximately 2.7 billion years ago. The main difference between these two types of creatures is that eukaryotic cells have a membrane-bound nucleus, whereas prokaryotic cells have not.
Therefore, option (C) is correct because prokaryotes are the simplest cellular organism while eukaryotes are complex multicellular.

fungi

Answer:
Fungi
Explanation:
Fungi (such as mushrooms) are eukaryotic and multicellular. They are decomposers, which means they feed on dead and decaying organisms. If the question was only asking for one that feeds on dead and decaying organisms, the answer could also be bacteria, for they are also decomposers, but bacteria are prokaryotes and unicellular.
In pea plants, flower color and the length of the flowers pollen grains are genetically determined.
a. True
b. False
Answers
The expression of flower color -qualitative character- and the length of the pollen grains -quantitative continuous character- is controlled by genes. Option A) TRUE.
How are characters expressed?Characters might be either qualitative or quantitative, discrete or continuous. In any case, genes are the units that control the expression of these characters.
A gene might be diallelic or multiallelic, and a character might be coded either by a single gene or by multiple genes.
The expression of the individual's phenotype varies according to the interaction between the involved genes and the inheritance pattern.
So characters are genetically determined. However, we need to consider that phenotype is also influenced by the environment.
Individuals are exposed to different environmental pressures that might lead them to express a different phenotype.
The phenotype depends on the interaction between the genotype and the environment. The environment, for instance, has a significant influence on the expression of quantitative characters like the length of the pollen grain.
In the exposed example,
flower color is a qualitative characterthe length of the flowers pollen grains is a quantitative continuous character
Both of them are coded by genotypes. This is, their expression depends on the involved genes. However, in the case of lengths, the environment also plays a significant role in its expression.
Option A is correct. The statement is TRUE.

Why are cetacean are smarter than primates?
Answers
Answer:
well no duh we humans we smart and we invented half the stuff in the world
Explanation:
Answer:
Evolution and different environments.
Explanation:
Primates are intelligent in their own ways, such as motor control, the use of hands and feet simultaneously, control of both hands for different things at the same time.
Dolphins for example, however, they lack the limbs that primates do, so they don't need motor control as much as primates. They evolved to be very social animals, and that allows them to excel in groups while maintaining a pattern seeking brain much like primates, without the motor control capabilities.
