Answer:
The Montreal Protocol, finalized in 1987, is a global agreement to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS).True or false? Genes that are very far apart from one another on the same chromosome may be indistinguishable from genes on separate chromosomes in genetic linkage studies.
O True
O False
This is true that Genes that are very far apart from one another on the same chromosome may be indistinguishable from genes on separate chromosomes in genetic linkage studies.
The probability of two genes inheriting together increased depending on how close they were to one another on a chromosome. On the other hand, genes on the same chromosome that were more apart from one another were more likely to be split apart during recombination.
Every time a pair of genes on a chromosome that far apart crosses over, an equal number of parental and recombinant chromosomes are created.
Linkage is the propensity for genes on the same chromosome to pass down their mutations together.
Unlinked genes refer to genes that are spread across various non-homologous chromosomes.
Linked genes are genes that are found on the same chromosome.
The tendency to display full linkage indicates that genes near to one another are highly related.
Different chromosomes' genes frequently have insufficient linkage.

After watching the CrashCourse video on Taxonomy: Life's Filing System, write a summary of three things you
learned about taxonomy from the video. Zooalogy
Watching CrashCourse video, I learned the 3 basic elements of taxonomy, which are the three domains are Archea (formed by prokaryotic beings, such as archaea), Bacteria (formed by prokaryotic beings, such as bacteria and cyanobacteria) and Eukarya (formed by eukaryotic beings).
What is the concept of taxonomy?Taxonomy is the branch of biology responsible for identifying and classifying all animals and plants that inhabit the Earth, based on the different characteristics they share with each other.
What is taxonomy and examples?Taxonomy is the area of Biology that classifies, organizes and describes living beings. It is like a library that organizes each group into its categories, in an order that facilitates understanding and searching for features.
With this information, we can conclude that Taxonomy is a method used in biology to name, identify and classify living beings.

what is the source of mold on bread
Answer:
Well, mold develops and grows eventually forming a colony due to spores landing on the bread and multiplying, hence growing the mold.
Where does mold on bread come from?
On bread, molds (many colonies of various sorts) develop from microscopic fungi that float in the atmosphere.
The fungus that causes mold develops as extremely little filaments called hyphae, which enable the fungus to float and be transported by the air. The hyphae spread by forming an apparent, hairy network when they land on bread or other organic materials. The color of the spores that develop on the end of the hyphae determines the color of the mold network .There are molds that grow as single-cell spores as opposed to mold that grows as multicellular hyphae with a spore at the end. They are known as yeast.

Which parts of a plant are responsible for reproduction? Describe the role that each of them will play.
Describe what occurs during the process of seed development.
Based on your knowledge of flowers, why do you think most flowers are bright in color?
The parts of a plant that are responsible for reproduction are the flowers, they are present only in the most evolved group of plants called angiosperms. Flowers can be hermaphroditic or monoecious when they have both female (carpels) and male (stamens) structures.
Describe what happens during the seed development process.Germination is a succession of stages that resume the development of the embryo and the beginning of the formation of a new seedling. We can summarize germination as the process of transforming the seed into a new plant. The seed consists of the embryo, endosperm and integument.
Based on your knowledge of flowers, why do you think most flowers are brightly colored?Are mainly related to pollination by animals. This is due to the fact that the flower acts as a form of attraction for pollinators, therefore, mechanisms are needed to guarantee the visitation of these animals.
With this information, we can conclude that flowers inherit their appearance through genes. Pigments are born in these plants, producing a range of colors across the spectrum. The same chemical, carotenoid, that produces the pigment in tomatoes and carrots also produces the yellow, red, orange colors in certain flowers.

The truck carrying heavy loads have more tyre.Give reason.
Answer:
the load carrying heavy vehicles have large number of wheels so that the pressure on the road is reduced due to larger contact area.
Also, using large number of wheels ensures that the force due to the load is shared among the tyres and no single tyre is under stress.

The Eocene occurred during the Terciaty period. To determine the era the Eocene period belongs to, a scientist should study information related to the Cenozoic era. Option B).
What is the Cenozoic?The Cenozoic is an era that covers the period from 65 million years ago to the present.
Significant events during the period,
During this era, there is a decrease in temperature (which until that moment was significantly higher than the current temperatures) and begins an aridity process.Since most cretaceous plant species got extinct, there is significant radiation of angiosperm and their consequent domain on the ground.
Following this diversification, different insects evolve following the different types of plants. Coevolution and pollination acquire protagonism.
During this period, mammals radiated too, originating in the current region of China.
Occurs the evolutive radiation of teleosts and birds.
The Cenozoic era includes the tertiary and quaternary periods.

Temperature affects photosynthesis in water
weed. She has been given the equation:
light energy
glucose + oxygen
Carbon

What should she investigate?
She should investigate how temperature affects the rate of oxygen production.
PhotosynthesisDuring photosynthesis, green plants make use of inorganic products in the form of water and carbon dioxide to synthesize carbohydrates. The reaction only happens in the presence of solar radiation and oxygen is evolved as a by-product.
The process involves a series of chemical reactions. However, the summary of the whole reactions is represented by the following equation:
carbon dioxide + water ----> glucose + oxygen
Thus, if Emily is to find out how temperature affects photosynthesis. She will need to use a plant as a case study. One factor that can easily be used to measure the rate of photosynthesis is oxygen production by plants.
In other words, Emily will have to set up an experiment where a plant species will be subjected to the same environmental conditions, except temperature. Then, a suitable method will be used to measure the amount of oxygen produced. Any difference in the volume of oxygen produced can then be attributed to the effects of temperature.
