Answer:
What happens is the dehydration phenomenon.
Explanation:
The phenomenon of dehydration occurs because when you are at sea for many days, you breathe the salty mist that occurs on the surface of the sea (which is even greater at night), this mist is high in solutes and salts that is why that when inhaled, the body will seek to increase blood volume to lower the plasma concentrations of these solutes in the blood.
Also, during breathing, a lot of water is lost and other physiological processes are why we need a daily consumption of water.
In the case of this situation where the person is abandoned, water consumption is low.
The consequences of dehydration are serious, since there is hypotension, decreased blood volume, hypovolemic shock, loss of consciousness and even possible death.

Tomas had low levels of calcium in his body. Vitamin D is essential in maintaining a calcium balance. He started taking vitamin D supplements. Because Tomas took high doses of vitamin D, the calcium levels in his body increased. Which endocrine glands will help maintain homeostasis by regulating the increased calcium levels?
Answer:
calcitonin
Explanation:
Calcitonin is a hormone which helps in lowering the high blood calcium levels. It is secreted by thyroid glands. Parathyroid glands are responsible for increasing calcium level in the blood while calcitonin hormone work against parathyroid glands and helps in lowering calcium level. Calcitonin hormone inhibit the activity of osteoclasts which are responsible for releasing of calcium from bones into the blood.

Fats and steroids are both hydrophilic lipids, but fats help with metabolism while steroids provide insulation. Fats and steroids are both hydrophobic lipids, but fats serve as energy while steroids serve as hormones. Steroids contain a four-carbon ring while fats consist of glycerol and fatty acids, but both are proteins. Steroids help with transport while fats store energy, but both are proteins.
Answer:
Fats and steroids are similar because fats & steroids are both lipids & are both hydrophobic. They are different because fats store energy for molecules & steroids function as a messenger around the cell membrane.

Organisms exhibit different types of adaptations as a means of survival. What type of adaptations do the caterpillar and the plant show in this interaction?
Answer:
The type of adaptations exhibited by both organisms depends the effects each exhibited on the other.
When natural selection acts on the variation passed from generations to generations in a population,the organism involved are best fitted to survive in their habitats.The Ability of species of organisms to be best fitted against the selective pressure,so that it is naturally selected in the population is called adaptation.It is one of the driving force of evolution.
in this scenario the caterpillar,is camouflage by its green color,which blend with that of the leaves.And therefore ensure the escape from the predators e,g birds,spiders,reptiles This is an example of structural adaptation.Since it is the structural characteristics of the caterpillar that adapted it to its environment.
Likewise in the case of the plants,despite harbouring the caterpillar it ensures it does not destroy it physiological make up,by releasing chemical substances to keep away the organisms.This is called physiological adaptation,because certain biochemical substances are diffused by the plants in response to the caterpillar (stimulus), to keep off the organisms away,to ensure the survival of the leaves.Since physiology is the study of function of an organisms,changes in biochemical and cellular reactions must be responsible for the biochemical substances produced.

Which of the following actions involves voluntary muscle movement? A.movement of food through the digestive tract B.movement of blood through the blood vessels C.beating of the heart D.making of faces
Answer:
D. Making of faces
Explanation:
Voluntary muscle movement is where us humans can choose to move and control how our muscles move.
The first three answer choices are involuntary, since the body does that itself without us controlling it.
However, making faces is voluntary and we choose to do that.
Making of faces is the action that involves voluntary muscle movement. Therefore, the correct option is D.
What is voluntary muscle movement?Voluntary muscle movement refers to the controlled, conscious contraction and relaxation of muscles that result in specific movements or actions.
This type of movement is initiated and directed by the conscious decision-making processes of the brain, and requires the activation of nerve cells that stimulate the muscles to contract.
Examples of voluntary muscle movements include movements such as walking, running, jumping, lifting objects, playing sports, making different type of faces and performing other types of physical activities. Therefore, the correct option is D.

In this assignment, you will conduct research to construct an explanation of how macromolecules are used in the body. You will then revise your explanation based on new information from additional research.
Answer:
Macro-molecules are used in the body after the conversion of micro-molecules.
Explanation:
Macro-molecules such as protein, carbohydrates and fats etc are bigger in size which can not be absorbed by the cell of the body so these Macro-molecules first broken down into micro-molecules such as amino acids, glucose and fatty acids etc. Protein is converted into amino acids, carbohydrates is converted into glucose and fats is converted into fatty acids by the action of different enzymes. These micro-molecules are used by the cell in order to generate energy.
Answer:
Macromolecules are important for the body and therefore, are used frequently. For example, “macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions.” There are four major types of macromolecules, those of which are as follows; proteins, carbohydrates, nucleic acids, and lipids. All of these play these important roles in the life of a cell. Macromolecules such as protein, carbohydrates and fats are bigger in size which can not be absorbed by the cell or the body, so these macromolecules are first broken down into micro-molecules, such as amino acids, glucose and fatty acids, etc. Protein is converted into amino acids, carbohydrates are converted into glucose, and fats are converted into fatty acids by the action of different enzymes. Proteins use amino acids which provide cell structure, send chemical signals, and speed up chemical reactions. Nucleic acids use nucleotides that store and pass on genetic information. Carbohydrates use monosaccharides (aka simple sugars) to provide cells with quick, short-term energy and a source of dietary fiber. Lipids use fatty acids and glycerol to provide cells with long-term energy, and they make up biological membranes. That is how macromolecules are used in the body.

Do you know the Transcription factor name for lapF and naphthalene dioxygenase?
Answer:
The LapF gene encodes one of the largest proteins from Pseudomonas putida, it is required for the bacterial colonization on the solid surfaces; while naphthalene dioxygenase is an enzyme required for the process of aerobic degradation of naphthalene.
Explanation:
LapF is a gene of Pseudomonas putida that is critical during the process of plant root colonization. Mutations in this gene have shown to reduce the ability to colonize plant tissues. On the other hand, the naphthalene dioxygenase gene is also encoded by the genome of Pseudomonas strains. The naphthalene dioxygenase protein catalyzes the hydroxylation of different substrates, however, this enzyme is widely known for acting during the degradation of naphthalene, an organic chemical compound that is toxic in humans.

Compare and contrast the reproductive cycles of a flowering plant and a human. Include two similarities and two differences in your answer.
Answer:
Similarities: 1) They both reproduce sexually by fertilization 2) They both have male and female reproductive parts
Differences: 1) Plants can either be monosexual or bisexual while humans are always bisexual
2) Plants employ double-fertilization while humans don't
Explanation:
All organisms including plants and humans have to reproduce in order to produce young generations. However, there are similarities and differences between the reproductive cycles of these organisms. According to the question, we'll be comparing and contrasting reproduction in flowering plants and humans.
SIMILARITIES:
Both flowering plants and humans have sexual means of reproducing, which involves fusion of male and female gametes to produce a ZYGOTE, a process called FERTILIZATION.
Also, the opposite gametes that fuses during fertilization are produced by distinct male and female parts on both flowering plants and humans. For example, the anther produces the pollen containing the male gametes, while the ovary produces the egg cells in flowering plants. The testes and ovary produce the sperm and eggs in humans.
DIFFERENCES:
Flowering plants can either be monosexual i.e. bear both male and female reproductive structures on same plant or bisexual i.e bear the different reproductive structures on different plants. Humans are always bisexual i.e. they bear different reproductive structures depending on the sexuality.
A phenomenon unique to flowering plants called Double Fertilization occurs. This is a process whereby a triploid endosperm is formed from the fusion of two haploid nuclei with a sperm cell. This process only occurs in flowering plants and is absent in human reproductive cycle.

What is it called when plants lose water through their leaves?
A. Transpiration
B. Percolation
C. Precipitation
D. Condensation
Answer:
A. Transpiration
Explanation:
Transpiration occurs through the stomata of the leaves.
Hope it helps.
Transpiration is the term used when plants lose water through their leaves. transpiration is an important process for plants and for the Earth's water cycle, helping to regulate water balance, transport nutrients, and regulate temperature. Hence option A is correct.
What is transpiration?Transpiration is the process by which plants lose water from their leaves through tiny pores called stomata. Stomata are located on the underside of the leaves, and they allow water vapor to escape from the plant into the surrounding atmosphere. Transpiration is a vital process for plants as it helps to regulate their internal water balance and temperature.
During transpiration, water is drawn up from the soil through the plant's roots and into the leaves. Water is then released through the stomata as water vapor, which evaporates into the air. This process is driven by the plant's need to transport nutrients and minerals from the soil up to the leaves, and to regulate its internal temperature.
Transpiration also plays an important role in the global water cycle, as it contributes to the amount of water vapor in the atmosphere. This water vapor can then condense to form clouds, which can lead to precipitation in the form of rain or snow.
Hence option A is correct.

A person in a dark room looking through a window can clearly see a person outside in the day light . But a person outside cannot see the person inside
Explanation:
The explanation for this is that the space outside is illuminated with light from the sun. The person inside has either a lesser or no illumination at all. The dark inside room appears dark, and darkens the surface of the window facing inside, making it act like the silvered surface of a mirror. When the outside observer looks at the window, the window acts as a mirror, reflecting the light from the sun onto the eyes of the outside observer. For the inside observer, some of the illumination from outside finds its way inside, since the outside window surface is well lit, carrying with it the sensation of vision onto the eyes of the inside observer.

how are the respiratory and circulatory systems connected
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
The respiratory and circulatory systems bring oxygen and nutrients to the cells. The respiratory and circulatory systems work together to maintain homeostasis. The respiratory system moves gases into and out of the blood. The lungs contain the bronchi, bronchioles, and alveoli.
The circulatory and respiratory systems work together to maintain homeostasis.
