1. Science is the greatest collective endeavor. It contributes to ensuring a longer and healthier life, monitors our health, provides medicine to cure our diseases, alleviates aches and pains, helps us to provide water for our basic needs – including our food, provides energy and makes life more fun, including sports, music, entertainment and the latest communication technology. Last but not least, it nourishes our spirit.

 

2. Science generates solutions for everyday life and helps us to answer the great mysteries of the universe. In other words, science is one of the most important channels of knowledge. It has a specific role, as well as a variety of functions for the benefit of our society: creating new knowledge, improving education, and increasing the quality of our lives.

3. Science must respond to societal needs and global challenges. Public understanding and engagement with science, and citizen participation including through the popularization of science are essential to equip citizens to make informed personal and professional choices. Governments need to make decisions based on quality scientific information on issues such as health and agriculture, and parliaments need to legislate on societal issues which necessitate the latest scientific knowledge. National governments need to understand the science behind major global challenges such as climate change, ocean health, biodiversity loss and freshwater security.

4. To face sustainable development challenges, governments and citizens alike must understand the language of science and must become scientifically literate. On the other hand, scientists must understand the problems policy-makers face and endeavor to make the results of their research relevant and comprehensible to society.

5. Challenges today cut across the traditional boundaries of disciplines and stretch across the lifecycle of innovation -- from research to knowledge development and its application. Science, technology and innovation must drive our pursuit of more equitable and sustainable development.

Vegetative propagation

Cutting is a form of vegetative propagation attribute of some organisms.

Cutting a tissue off a plant and the tissue developing its own root to become a new plant happens by mitosis.

Mitotic division of the cut tissues leads to the formation of roots and the eventual growth to a new plant.

Mitotic growth means that the new plant will be genetically and physically identical to the parent plant, provided they grow under the same conditions.

A. geosphere
B. mountains
C. coastlines
D. dunes
E. elevation

Answers

Answer:

B,C and D

Explanation:

These are landforms because if you were to travel to the location they were seen on the map they are visible

however Elevation is not a visible mass ( it is a characteristic of a location ) and geosphere is a general term to describe the sections of the earth and atmosphere

Hope this helps!

The three examples of landforms among the options provided are mountains, coastlines, and dunes.

What are landforms?

Landforms are natural features on the surface of the earth, such as mountains, valleys, plains, and coastlines, that have been shaped by various geological processes over time.

Mountains are large natural elevations of the earth's surface, while coastlines are the landforms where the land meets the sea, often characterized by cliffs, beaches, and bays. Dunes are hills of sand that form in deserts or near beaches due to the movement of wind.

The geosphere refers to the solid, rocky part of the earth's surface, which includes the lithosphere (outermost layer of the earth's crust) and the underlying mantle, and is not considered a landform. Elevation is a term that refers to the height of a landform relative to sea level, rather than being a landform itself.

what are some drawbacks to using mice in genetic studies?

Answers

Answer:

One drawback to using transgenic, knock-in, and knock-out mice to study human diseases is that many disorders occur late in life, and when genes are altered to model such diseases, the mutations can profoundly affect development and cause early death.

hope this helps

Explanation:

Genetically altered mice have served to recapitulate human diseases, including cancer, glaucoma, heart disease, and diabetes. However, despite their genetic similarity to humans, mouse models are criticized for their failure to accurately mimic human disease phenotypes.

Why it's bad to use mice as an experiment:

The use of mice as model organisms to study human biology is predicated on the genetic and physiological similarities between the species. Mice are less reliable as models of human disease, however, because the networks linking genes to disease are likely to differ between the two species.

The published data for the map distance between the gene and the centromere is 26 map units. You just calculated the map distance as 17 map units. What is the best explanation for this disparity

Answers

Linkage maps and physical maps are NOT the same. A linkage map measures the number of recombination events in a given chromosome fragment.

A linkage map is based on the frequency of recombination events between genes or molecular markers.

This frequency indicates the number of events in which a single chromosomal fragment recombines between two or more genes or molecular markers during meiosis.

Conversely, a physical DNA map indicates the physical locations of genes (molecular markers) and nucleotide (DNA) sequences of interest, which is useful to identify genes by positional cloning.

Which is the better soil amendment: compost, vermiculite, and manure? Why?

Answers

Answer:

All of them are great, but compost and manure are probably best because they still have protiens and energy stored in them.

Have an awesome day friend! :D

Explanation:

Compost: (permeability, water retention, nutrients) Well-rotted compost is one of the best soil amendments you can add to your garden, and it’s impossible to use too much! Compost is highly fertile and lightens heavy soils while providing structure to loose soils. It also possesses the amazing ability to help soil retain much needed water while improving drainage – making compost great for both clay and sandy soils. Compost lasts about six months but has a long-term impact on soil microbes and overall fertility. Continue to add compost, and watch your soil get better and better.

Greensand: (provides permeability, nutrients) This powdered rock material provides slow release nutrients, such as potassium and other trace minerals. It also helps loosen compacted soil.

Sand soil amendment

Sand soil amendment.

Gypsum: (permeability for saline soils) While powdered gypsum is considered an amendment for clay soil, it’s actually more important for saline soils where it loosens the clay by reacting chemically with the salts.

Leaf Mold: (water retention, texture, nutrients) Made from shredded, composted leaves, leaf mold holds moisture, loosens soil, provides organic matter, and breaks down slowly to improve overall soil texture. Leaf mold also encourages beneficial microbes that help transfer nutrients to plant roots.

Manures: (texture, nutrients) Composted manures are affordable, readily available soil amendments. Like other forms of compost, manure provides the right balance of drainage and water retention. Manures are high in nitrogen and other nutrients, so they’re particularly useful as slow release fertilizers. Manures can add salt to the soil, so they may not be suitable if your soil is already saline. Use only well rotted manure to prevent burning due to high nitrogen content.

Causal attribution theories generally try to explain how we:

1) are influenced by others

2) predict how others will behave based on their attitudes

3) change our attitudes toward other people

4) determine the causes of others' behavior

5) relate to and interact with other people

Answers

Causal attribution theories generally try to explain how we determine the causes of the others' behavior based on personal or situational attributions.

This theory was developed by Horald Kelly in 1967, and explains how people attribute the behavior of others according to dispositional (internal) and situational (external) factors.

Dispositional factors are those based on internal characteristics, such as effort and skill. Situational factors, on the other hand, are environmental and external to the individual, such as luck and task difficulty.

Therefore, according to theory we are more likely to attribute the cause of the behavior of others to factors that most coincide with the action.
