How does the experiment relate to what you've learned about submersible technology suck as submarines and ROV's?
Answer:
A submersible technology designed to operate the submarines underwater.
Explanation:
We have learned about submersible technology suck as submarines and ROV's is that pumping system is used to remove water from the submarines and ROV's in order to make it lighter. A submersible is designed to push water to the surface. When a pressure switch is turned on, the impeller started to spin drawing water into the pump. The water is then pushed through the pump and brought it to the surface. Due to removal of water, the submarines and ROV's become lighter and they will come to the surface of water.

ILL GIVE BRAINLIST PLS HELP
Answer:
1.In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
2.Survival of the fittest is a simple way of describing how evolution (the process by which gradual genetic change occurs over time to a group of living things) works. It describes the mechanism of natural selection by explaining how the best-adapted individuals are better suited to their environment.

After you eat lunch, nerve cells in your stomach respond to the distension (the stimulus) resulting from the food. This is best described as a mechanism between:
Answer:
stimulus, control center
Explanation:
The control center is the main nervous system of the brain that is used to carry out different sensory, the motor and integration of data.
The stimulus control is the behavioral control that is described as the situations where behavior is triggered by the presence or the absence of any stimulus. Stimulus is the functional reaction in a tissue or any organ.
In the context, the nerve cells in the stomach responds to the stimulus that results from the foods after eating food is a mechanism between the stimulus and the control center.
In a population of wild bees, a mutation resulted in slightly larger wingspan in some of the bees. This larger wingspan made the bees more efficient in their flights to flowers to collect nectar. Thus, these bees became more successful. This trait was passed on to offspring, and eventually the larger wingspan variety of bee replaced their smaller-winged relatives completely. It could be said that ____ favored the bee with the larger wingspan, and so the ____ evolved
Answer:
The correct answer is - natural selection, population.
Explanation:
In this case, the wild bees population experienced a mutation which helps in become more eeficient to fight for nector. This bees population is more sucessful to other that didnt recieved mutation and this mutation as it is adavtageous.
Natural selection always favored beneficial traits for the organisms to eveolved in generation therefore, these population is more succesful and replaced the short winged bees.
Which type of protein would more likely be able to function as a channel through the plasma membrane
Answer:
Aquaporins
Explanation:
Aquaporins are the channel proteins that is present in the membrane of the cell which allow water to cross the membrane very quickly. This aquaporins play an important roles in plant cells, red blood cells, and certain parts of the kidney where this protein minimize the amount of water lost as urine. Without this protein, the diffusion of water across the cell membrane is not possible very quickly.

Identify and describe how bacteria, hormones, and nerves influence the health and activities of the GI tract
Answer:
The GI health is supported by a varied and rich population of bacteria. The GI processes are controlled by the coordinated efforts of the hormonal system and the neurological system. Digestion and absorption together break up diets into bodily nutrients. A healthy GI system requires a balanced diet, sufficient relaxation, and frequent physical activity, to perform best.
Explanation:
Bacteria along the GI tract have a wide range of possible health benefits, including the production of vitamins, ion absorption (Ca, Mg, and Fe), pathogens protection, histologic development, improved immune systems, and fermentation of "no-digestible food" Bacteria have a number of potential functions.
During the digestion and absorption process hormones control the different digestive enzymes, which are secreted in the stomach and bowel. In reaction to the consumption of food, for example, the hormone gastrin induces stomach acid output. The somatostatin hormone prevents stomach acid secretion.

Identify the following by typing (a) for mitosis or (b) for meiosis on the line before the statements: _____ produces 4 unique gametes _____ begins with a somatic cell _____ produces only 2 identical cells _____ has only one nuclear division _____ happens in the testes and ovaries _____ daughter cells are haploid _____ has two nuclear divisions _____ daughter cells are diploid
Answer:
b - produces 4 unique gametes
a - begins with a somatic cell
a - produces only 2 identical cells
a - has only one nuclear division
b - happens in the testes and ovaries
b - daughter cells are haploid
b - has two nuclear divisions
a - daughter cells are diploid
Explanation:
Mitosis is a kind of cell division that involves the formation of two daughter cells, which are genetically identical and have the same number of chromosomes as their parent cell (diploid). Mitosis occurs in body or somatic cells for repair and multiplication. Mitosis involves only one nuclear division.
Meiosis, on the contrary, involves formation of four daughter cells that are genetically different from the parent cell and have a reduced chromosomal number (by half). Meiosis occurs in reproductive cells like tested or ovaries. Meiosis occurs in two nuclear divisions.

Write a supported hypothesis of how the body would react if the peripheral nervous system was shut down while the central nervous system continues to function.
Explanation:
The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:
They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.
Pesticides are: Group of answer choices Always highly toxic to humans All of the listed answers All synthetic chemicals Always the best weapon against insect pests None of the listed answers
Answer:
Always highly toxic to humans.
Always the best weapon against insect pests
Explanation:
Pesticides are always highly toxic to humans as well as all synthetic chemicals are always the best weapon against insect pests because the chemicals used in these pesticides affect the body structure as well as other mechanism of survival for the insects or pests. The ingredients present in pesticides are highly toxic to humans which leads to the death of human while on the other hand, it is the best weapon used by humans against pest.

Why do you think scientists track the genes of other organisms such as rats or mice in the database? Do you think rat genes are important to human gene research?
Scientists study and track other animals' genes in an effort to understand how non-human creatures' genes work and operate. They do this to understand genetic risk factors in illnesses in the human population. This comes primarily from research on the genes of mice because mice are incredibly genetically close to humans --- there are literally thousands of genes in mice and rats that are phenomenally similar to humans. Manipulating their genes is extremely simple, such as adding or deleting genes to better understand their bodily functions --- also known as genetic engineering. The majority of mice and rats used in genetic research and medical studies are inbred and genetically similar, which makes the medical trial outcomes more consistent. This helps us find an understanding in whatever it is that we're trying to find.
Scientists track the genes of other organisms like rats and mice in databases because these organisms share evolutionary similarities with humans, allowing researchers to study biological processes, diseases, and potential treatments that can apply to humans.
Rat genes are important to human gene research due to their similarities and potential for modeling human diseases and drug responses.
Scientists track the genes of various organisms, including rats and mice, in databases because these organisms serve as valuable model systems for studying biological processes, genetics, diseases, and potential treatments that are relevant to humans. Despite the differences in size and appearance, many biological functions and genetic pathways are conserved across species due to evolutionary relationships.
Rats and mice share a significant portion of their genes with humans and have similar anatomical and physiological characteristics. This similarity allows researchers to study fundamental biological mechanisms and disease processes in these animals and extrapolate the findings to humans. By tracking the genes of these organisms in databases, scientists can access a wealth of information about their genetic makeup, which aids in designing experiments and conducting comparative studies.
Rat genes, in particular, are important to human gene research because rats have a similar genomic organization and share many orthologous genes with humans. Rats are used extensively in medical and scientific research as model organisms to study human diseases such as cancer, cardiovascular disorders, diabetes, neurological conditions, and more. Their genetic and physiological similarities enable researchers to mimic disease processes and test potential therapeutic interventions in rats before moving to human clinical trials.
In summary, tracking the genes of organisms like rats and mice in databases is essential for advancing our understanding of genetics, diseases, and treatments that apply to humans. Rat genes are valuable in human gene research due to their evolutionary relationship with humans and their potential for modeling human diseases and drug responses, ultimately contributing to the development of medical treatments and therapies.

In interstitial growth of cartilage ______. Multiple choice question. only new cells are produced only new matrix is produced news cells and new matrix are produced
Answer:
The correct answer is ''news cells and new matrix are produced''
Explanation:
Interstitial growth consists of the production of new layers of cartilage in the inner layer of the perichondrium. This process occurs because chondrocytes meet in the form of small groups, called isogens or cell nests, they are capable of dividing and the cartilaginous matrix is distensible. Daughter cells initially occupy the same gap but as they secrete new intercellular matrix they separate. These daughter cells can divide again, forming so-called isogenic groups, which are frequently found in growing cartilage.
