What need to be changed is ; The use of selectively/semi-permeable membrane
To selectively allow the passage ( diffusion ) of a certain type of solute through a membrane in a solution, we should make use of a selectively permeable membrane which allows only the passage of a certain type of solute contained in the solution ( like the green solutes ).
The use of permeable membrane in a solution is to selectively allow flow of solutes or solvent from a region of lower concentration to a region of higher concentration.
Hence we can conclude that what needs to be change is The use of selectively/semi-permeable membrane will allow only the green solutes to diffuse across.

Which of the following is a source of energy made from plant and animal remains?
Answers
In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.
These are sometimes known instead as mineral fuels.
The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.
A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.

Which of the following is not one of Mendel's Laws?
a) Law of Conservation of Mass
b) Law of Segregation
c) Law of Dominance
d) Law of Independent Assortment
Answers
Answer:
A
Explanation:
Law of conservation of mass was discovered by Lavoisier
Law of Conservation of Mass is not one of Mendel's Laws. Therefore, the correct option is A.
What are Mendel's Laws?Gregor Mendel's research with pea plants in the 19th century led him to reveal three fundamental laws of inheritance, known as Mendel's laws. There are three laws:
1. Law of Segregation: Each individual has two alleles for each trait, and this law indicates that these alleles separate (separate) during the development of gametes, or reproductive cells. This indicates that only one allele per trait is present in each gamete.
2. According to the law of independent assortment, the inheritance of one trait is independent of the inheritance of another. In other words, the segregation of alleles for one trait is independent of the segregation of alleles for the other trait.
3. The law of dominance states that when two different alleles are present in an individual, the dominant allele will dominate the recessive allele in terms of expression. Only when both alleles are recessive will the recessive allele be expressed.
Therefore, the correct option is A.

Also describe how fungi are helpful and harmful to humans and other organisms. ( put this in a paragraph also please)
Answers
Answer:
Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.

functional group of Acetaldehyde
Answers
Answer:
―CHO
Explanation:
Organic compounds are compounds that contain carbon-hydrogen bonding in their structural formula, hence, virtually all organic compounds are referred to as HYDROCARBONS. Organic compounds consists of a wide variety of groups, which are individually identified by their FUNCTIONAL GROUP.
The functional group of an organic compound is responsible for its chemical behavior irrespective of other atoms in its structure. According to this question, ALDEHYDE GROUP is an organic compound also called ALKANAL. It has the functional group as follows:
R - C - H - O
Where R is a side chain
- The second member of the aldehyde group is called ACETALDEHYDE with the chemical formula; CH3CHO. Since it is a member of the aldehyde group, its functional group is -CHO.

How are traits inherited by offsring?
Answers
a trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. If a gene pair contains a dominant allele, then the offspring will show this dominant trait.
step by step:
Answer:
Traits are passed to offspring by the offspring parents.
Explanation:
the genes that control a trait come in pairs, one from each parent. If a gene pair contains a dominant allele (a variation of genes that will produce phenotype,) than the offspring gains that trait from the dominant parent.

Answers
Answer:
camptosaurus
Explanation:
I think it's correct
The Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.
What is Evolution?Evolution may be characterized as the complete methodology of gradual change that takes place over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
Coelophysis lived during the late Triassic period some 216.5 to 203.6 million years ago. Researchers believe that this small theropod lived on river floodplains where it walked alongside crocodilian-like Camptosaurus. They were small theropod dinosaurs that lived in what is now North America and Southern Africa during the late Triassic.
Therefore, the Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.
