Answer:
To find the number of electrons an atom has, start by looking up the element you're working with on the periodic table and locating its atomic number, which will be in the upper left-hand corner of the square. Then, identify the charge of the ion, which will be written as a superscript to the right of the element.

The rate at which a parent atom creates daughter atoms is always
1.unstable and changing
2.constant and unique
3.unstable and rare
4.never found in nature
Answer:
2. Constant and unique
Explanation:
The rate at which a parent atom creates daughter atoms is always constant and unique. The process of cell division is a unique occurrence that happens with eukaryotic cells. These parent atoms go through the different phases at a constant phase, but when interruptions in the divisions happen, mutations and abnormality in the cell will take place.
the difference between mixture and compounds is that mixtures change their properties and have to go through a chemical change this is not true of compound

H = brown hair
h = red hair
Mother: Hh (heterozygous It’s given)
Father: hh (homozygous, given)
What is homogeneous and heterogeneous?Homozygous means alike allele whereas heterozygous means unalike or distinct from one another.
So, in the punnet square below, it is shown that there is a 50/50 chance for the offspring to have red hair.
Ratio is 1:1.
But there is also another probability for the offspring to be like their mother, have the dominant gene of black hair overruling the recessive gene of red hair.

Space travel has come a long way since Laika, but there are still many celestial bodies waiting to be explored. What do you think will be the biggest space mission of the twenty-first century? What challenges do you anticipate that the humans or space probes will experience on this journey? What specific accommodations or technological advancements will be needed to make the mission successful?
Answer:
NASA's Artemis program has a goal of landing humans on the moon in 2025 to begin building a base camp. This long-term human presence on the lunar surface will help NASA prepare for human space exploration missions of greater distance and duration, including an eventual crewed flight to Mars. Space can help us prepare the feutre Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets. That has led to the development of various technologies that feed back into the economy and improve our lives on Earth. Without space programs, we wouldn't have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras.
Explanation:
There hope it helps Also you could've done a little bit of resheerch skimmed a cupple sights to get an idea on what to wright about then go from there its just an idea thoe
We have learned more about gravity, the magnetosphere, the atmosphere, fluid dynamics, and the geological evolution of other planets, for instance, through studying the solar system. This sparked the creation of numerous technologies that benefit the economy and enhance life on Earth.
What specific accommodations, technological space travel?In 2025, astronauts will be sent to the moon as part of NASA's Artemis mission to begin creating a base camp. This prolonged human presence on the moon's surface will help NASA get ready for longer-duration human space flight missions, such a possible crewed trip to Mars.
Additionally, you could have done some research by scanning a few websites to get an idea of what to write about before moving on from there.
Therefore, We wouldn't have GPS, precise weather forecasting, solar cells, or ultraviolet filters in eyeglasses and cameras without space missions. We can prepare the feutre by using space. We can use space travel to support or refute scientific hypotheses that were formed on Earth.

Answer
C02 is produced in the body.
Explanation:
Every tissue in the body utilize oxygen for its metabolic activities and excrete carbondioxide.Every tissue is supplied by blood. Blood transports oxygen from heart to the tissues used for metabolic activity.Tissue produces carbondioxide as a result of metabolism.Blood transports back carbondioxide from tissues to lungs to expel it out from the body. Inside the lungs, CO2 from blood vessels diffuse into lung tissue (simple diffusion) and then lungs exhale it. That'why there is additional percentage of carbondioxide in the exhaled air.
