Animals need water for crucial cellular processes and to prevent drying out. They require food to generate energy, maintain stable internal environment or homeostasis, and keep up body functions. While certain animals store fat for energy during food scarcity, regular intake of food and water is vital for survival.
Explanation:Animals cannot last without food and water for long due to several biological reasons. Water is critical for cellular processes, and if an animal is exposed to air, their bodies tend to lose water and risk of drying out. Biological adaptations help animals retain water, but they cannot survive without replenishing lost water for long.
Moreover, animals need food to maintain homeostasis, the ability to maintain a stable internal environment amidst external changes. Food provides the energy required for various body functions, including maintaining body temperature. Therefore, without regular intake of food, animals cannot sustain energy, and their vital functions start to fail, leading to survival risk.
Certain animals need excess body fat for insulation and energy storage during scarce food availability. However, periodical replenishment, either by eating or fat storage used for energy, is critical for survival on land.

what is not a characteristic of life?
Answer:
Immortality is not a characteristic of life.
Explanation:
Firstly the characteristics of life is responsiveness to the environment, growth and change, reproduction, metabolism, maintain homeostasis, being made of cell, and passing trades on to offspring.
We know that life is limited so immortality or unlimited duration of existence is not a characteristic of life.
The normal, or ________, eye accommodates properly.
The normal, or typical, eye accommodates properly for close and distant vision.
Explanation:The normal, or typical, eye accommodates properly. For close vision, the eye is fully accommodated and has its greatest power, whereas for distant vision, it is totally relaxed and has its smallest power. An 8% ability to accommodate is considered normal but is typical for people who are about 40 years old. Younger people have greater accommodation ability, whereas older people gradually lose the ability to accommodate.

Estimate how much the brain would swell due to osmosis if the concentration of the cerebrospinal ±uid fell to 280mm. in other words, ³nd what the new volume
Estimating how much the brain would swell due to a drop in cerebrospinal fluid concentration to 280 mm involves understanding osmosis and brain-CSF osmotic balance, which is crucial for preventing conditions like hydrocephalus. The exact new volume would need medical evaluation.
Explanation:The question concerns the phenomenon of brain swelling due to osmosis caused by changes in the concentration of cerebrospinal fluid (CSF). When the concentration of CSF falls, such as to 280 mm, water can flow into the brain cells due to osmotic imbalances, potentially leading to a condition like hydrocephalus. However, estimating the exact new volume of the brain due to osmosis requires sophisticated medical instruments and knowledge of osmotic pressure in the brain's environment. Normally, the pressure in the CSF ranges from 5 to 12 mm Hg, and deviations from this range can affect the brain's volume and pressure dramatically.
For example, if the gauge pressure in the fluid surrounding the brain increases significantly, it can lead to an increase in the outward force on the skull, even causing the skull to grow abnormally large in infants with hydrocephalus. In adults, a reduction in the CSF concentration can cause severe headaches and damage due to the brain resting upon the skull.
The specific volume change due to a CSF concentration drop to 280 mm would vary based on individual circumstances and would require medical assessment to determine.

Protein, nucleic acid, carbohydrate and lipid that are released from the cell.
Protein and nucleic acid are the two macromolecules that are also released from the cells when the cell is broken up because these two macromolecules are present in the cell and performs different types of functions that helps the cell in growth and development.
There are two more macromolecules are present such as carbohydrates and lipids in the cell that are also very important for cell so we can conclude that when the cell is broken, protein, nucleic acid, carbohydrate and lipid are released from the cell.

What happens to any matter that is not used by consumers in a food chain
Answer:
Material not consumed by consumers in the food chain generates the debris chain.
Explanation:
Debris chain, where the basis is non-living organic matter not consumed by consumers, is due to the decomposition of vegetable and animal bodies and their droppings. This matter is processed by decomposing microorganisms (fungi and bacteria), which release it in the form of plant nutrients, or in the form of debris that will be consumed by detritivorous organisms, in turn consumed by carnivores.

Investigate what newborn babies, skunk cabbage, hibernating bears, and a banned diet drug called dnp all have in common with regards to cellular respiration.
Final answer:
Newborn babies, skunk cabbage, hibernating bears, and DNP all reveal unique interactions with cellular respiration, relating to temperature regulation or metabolic rate variance.
Explanation:
Newborn babies, skunk cabbage, hibernating bears, and a banned diet drug called DNP all showcase unique aspects of cellular respiration. Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
Bears during hibernation slow down their metabolism and lower both heart rate and body temperature, thereby conserving energy. Newborn babies, especially preterm ones, might experience a condition known as non-shivering thermogenesis where they produce heat through metabolic processes due to their inability to shiver efficiently. Skunk cabbage can generate heat to help spread its scent and melt surrounding snow, a process known as thermogenesis. Lastly, the drug DNP interferes with the proton gradient in mitochondria, leading to an increase in metabolic rate and production of heat, which is why it was used as a weight loss aid before being banned due to toxicity. All these examples reflect on the diverse roles and behaviors of organisms or substances related to cellular respiration.

An allele is one of the alternative forms of a gene that governs a trait. If a fern plant is heterozygous for a particular trait, how can the alleles that control that trait be described? A. one dominant, one recessive B. two dominant C. three recessive, one dominant D. two recessive
Answer:
The correct answer is A. one dominant, one recessive
Explanation:
A gene can have many alternative forms called alleles. These alleles can be present in homozygous condition or heterozygous condition. In homozygous condition chromosome contains two same forms of an allele of a gene. In heterozygous condition a chromosome contains two different forms of an allele of a gene.
These alleles can be dominant or recessive. A dominant allele can be expressed in both homozygous and heterozygous condition, but a recessive allele will only express in homozygous condition.
So If a fern plant is heterozygous for a particular trait then it contains one dominant and one recessive allele because in heterozygous condition two different forms of allele is present. Therefore the right answer is A.
