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.
Scientists always prove or disprove their explanations by _____.
gathering evidence
using mathematical formulas
recording thoughts
doing laboratory experiments
Correct answer: A). Gathering evidence
The scientific explanation uses measurements and observations in order to explain something in the natural world. The Scientist uses the scientific method to collect evidence in the experiment that is related to the hypothesis.
They can gather the evidence by just observing the natural world and its phenomena or by performing an experiment in the laboratory or by running a model.
Hence, the correct answer would be option A.
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.

Explanation:
Genetics, botany, and zoology are all branches of biology, which is the correct answer to your question. Biology is the scientific study of life and living organisms, encompassing various specialized fields. For instance, genetics is concerned with how traits are inherited, botany focuses on the study of plants, and zoology is the branch that specializes in the study of animals. Other branches of science include fields such as physiology, the study of the functions of living organisms; geophysics, which explores the physical processes and properties of Earth; and agriculture, which involves the cultivation of plants and animals for food, fiber, biofuel, and other products beneficial to life.
Which best describes the vulva?
Answer:
The vulva refers to the female external genitalia.
It includes labia majora, labia minora, cli-toris, the opening of urethra, vagina, Mons pubis, and anus.
Cli-toris is located at the top of labia where internal labia meet.
The opening of the urethra is located just below the cli-toris through which a female excrete or pee.
Below the urethral opening, there present a vaginal opening. It provides the path for menstrual blood and babies to come out of the body.
Mons pubis helps in cushioning the pubic bone.
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.

) when cells are broken open, dna is released from cells into solution. name at least two other macromolecules that are also released from the cells, and the places they are found in the cells.
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.

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.

whats the relationship of the organelles of the endomembrane system
The organelles of the endomembrane system - the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles - interact and cooperate via direct contact or vesicle transfer. Their individual functions contribute to the overall function of the cell in terms of production, modification, transportation, and disposal of substances.
Explanation:The organelles of the endomembrane system are interconnected through direct contact or by the transfer of membrane segments as tiny vesicles. The endomembrane system consists of the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, and vacuoles.
The nuclear envelope is contiguous with the endoplasmic reticulum, which manufactures lipids and proteins. These products are then sent to the Golgi apparatus in vesicles, which modifies them for their specific functions and addresses them for transport to their proper locations. Lysosomes contain enzymes that break down waste materials and cellular debris, while vacuoles are storage organelles that can hold a variety of substances.
