Cyclins regulate the cell cycle by binding to cyclin dependent kinases, forming a protein complex.
Answer:
Fungi are eukaryotic organisms belonging to the kingdom fungi that are very widespread in most Earth habitats where they are primarily involved in recycling of nutrients and the decomposition of organic matter such that they aid in completing the food web and enabling the balanced ecosystem
In humans, fungi have the harmful effect of causing illnesses such as asthma, eye infections and are likely associated to alzheimer's disease as well as several other serious and some potentially lethal health conditions
However, fungi are known to aid humanity in such aspects including;
Natural pesticides
Agriculture
Food production
Medicine
Explanation:
Natural pesticides
Fungi which are pathogen of specific insect pest aid in the minimization of the harmful effect of pests on food crops such that microbial fungi pesticides can be sourced in the market
Agriculture
Fungi are necessary for the survival and growth of up to 80% of all grasses and trees
Food production
Fungi are well known for their role in bread, bear, and wine making and fungi are also used to ripen cheese
Medicine
Fungi are also used in the making of medicinal drugs such as penicillin G. Fungi and cyclosporine
A scientific theory can always be disproved if someone comes along with better evidence which shows another theory is true. However, most other theories are small improvements on existing ones. Evolution and natural selection (the theory that animals' populations change over time because their environment encourages specific different features for individuals that happen with mutation) was an improvement on the existing "theory" that animals were built to be fit for their environments. The earth rotating around the sun was a theory improving on the idea that the sun and the earth move around so that it looks like the sun moves around the earth. All of these happened because there was evidence, so while theories aren't always absolutely true, many modern theories are typically well-tested and if they aren't, they are usually refered to as hypotheses or models (although models can sometimes also be theories, like the Standard Model)
Answer:
NADPH is an activated carrier molecule that is used primarily by plants (NOT TRUE)
Explanation:
NADPH is indeed an electron carrier molecule that participates in various metabolic (anabolic) reactions carried out by plants, but it also participates actively in metabolic (anabolic) reactions carried out in animal tissues, this means that it is used by the cells of the human body as well.
A very important metabolic process in which the NADPH is produced is during the glucose 6-phosphate oxidation into phosphate pentoses through the pentose phosphate pathway. In this process NADP+ is the main electron acceptor, so when it is reduced it produces NADPH. <u>This NADPH is very important for the synthesis of fatty acids, cholesterol and various steroid hormones.</u>
Answer: Gametophytes
The female gametophyte is also commonly called the embryo sac or megagametophyte. The male gametophyte, also called the pollen grain or microgametophyte, develops within the anther and consists of two sperm cells encased within a vegetative cell
