Answer:

16) 6 electrons

17) 6 protons

18) 6 neutrons

19) 4 electrons

20) 6

Explanation:

There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.

Dweck uses the word predictability to describe the way our beliefs about ability dictate what goals we set for ourselves, what we think we can learn, and ultimately what we do learn.

Relation between predictability and mindset:

The sentence "Dweck uses the word predictability to describe the way our beliefs about ability dictate what goals we set for ourselves, what we think we can learn, and ultimately what we do learn" means that our belief system is responsible for our predictability, which influences the goals we set for ourselves, our knowledge, and what we learn in the end.

What is meant by mindset?

An individual's mindset is a significant predictor of their future success. The belief that our intelligence and abilities may grow and evolve over time and through the application of effort distinguishes a growth mindset from a fixed mindset. A fixed mindset is one in which a person believes that their abilities and talents are set in stone, and no amount of effort or learning can improve them.

Answer:

Answer is below.

Explanation:

Photosynthesis is a process that involves three main actors (or ingredients); sunlight, water, carbon dioxide.

Statistics has it that there was no sunlight all through the day.

- Let's check then if there was availability of water and the gas carbon dioxide.

There was rainfall all day

- This means that some photosynthetic activity would take place.

What about the gas that plants breathe in?

- There is always substantial amount of CO₂ in the atmosphere.

A SECOND WAY TO LOOK AT IT IS:

by checking the two stages of photosynthesis.

- In the first stage, sunlight is the main actor. Sunlight is trapped and stored as energy in the chloroplasts of green plants.

- In the second stage, CO₂ is the main actor. With CO₂, the chemical compound - from the first stage - ATP is used to produce sugar and organic compounds which are the food of/for green plants.

Answer:

\(Q = 5,46,000\) joules

Explanation:

As we know

\(Q = mc \Delta T\\\)

Q is the Heat Energy

M is the mass of the substance releasing /absorbing heat

C is the specific heat capacity \(= 4200\)  Joules per kilogram per degree

\(\Delta T\) is the change in temperature

Substituting the given values, we get

\(Q = 13 * 4200 * (35-25)\\\)

\(Q = 5,46,000\) joules

Two species are not likely to live together in the habitat for a prolonged period of time if they have the same manner of using resources, this is because of interspecific competition.

Any resources in a habitat are limited hence if species share common limited resources in a habitat they have to compete with others, this will be negative for both species at last only one species can survive in that habitat another one will go extinct. If two species need to occupy a habitat by sharing common resources they have to undergo resource partitioning. In this method, two species will form small microhabitats to share limited resources without competition. Microhabitats of one species will not be inhabited by other species. Resource partitioning can also be done by having different feeding times.

Answer: A natural disruption occurs when ice blocks a lake during the winter, resulting in a decreased food source for fish.

Explanation:

Events or processes known as "natural disturbances" take place in the natural world without human interference and have a big influence on ecosystems. In this instance, the lake's capacity to support fish is constrained by the creation of ice throughout the winter. As a barrier, the ice keeps sunlight from penetrating the water and reduces photosynthesis, and this in turn has an impact on the development of algae and other main producers. As a result, the lake's food chain is thrown off, which has an effect on the number of fish and their capacity to locate enough food.

DNA is important in identifying genetic relationships within a group, but it alone is not sufficient to determine complex social constructs like race, whiteness, or property; the inclusion of social, cultural, and historical factors is crucial in understanding these concepts.

Biological anthropologists and genome scientists should consider the relationship between Europeans and Indigenous people in their research to provide a more comprehensive understanding of human genetic diversity and population history.

DNA analysis can provide valuable insights into genetic relationships within a group, such as determining genetic ancestry or identifying related individuals. However, race, whiteness, and property are social constructs that go beyond genetic factors and are shaped by historical, cultural, and socioeconomic factors. These concepts are complex and cannot be solely explained by genetic data. Therefore, it is important for researchers, including biological anthropologists and genome scientists, to recognize the limitations of genetic data and consider the broader social context when studying race, whiteness, and property.

In the context of researching Europeans and Indigenous people, it is crucial for researchers to acknowledge and incorporate the historical and ongoing relationships between these groups. This includes understanding colonization, displacement, and the impact of power dynamics on genetic diversity and health outcomes.
