The first earthling to orbit our planet was just two years old. Her name was Laika, and she was picked up in the streets of Mosc

ow in 1957, just a few days before the launch of Sputnik 2. Laika was a terrier mutt, and her flight aboard Sputnik 2 paved the way for space exploration during a time when scientists weren’t sure if spaceflight was safe for living organisms. Since then, humans have orbited Earth and even walked on the moon. Currently NASA is planning a mission to send astronauts to a nearby asteroid, and commercial companies are planning civilian missions to the moon. Unmanned space probes have traveled past Neptune and Pluto to the outer edge of our solar system and entered interstellar space.
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?

i think since we have gone as far as our solar system boundaries the next big thing to achieve is to actually travel to another solar system, the challenge that would face anyone trying to reach another solar system is the distance, the distance is too long to cut with a speed slower than the speed of light in fact even the speed of light is not convenient for someone to travel and reach the other side before he dies and nothing can reach or exceed the speed of light because then they would lose their mass to energy, two proposed technologies to get past that is hibernation which is keeping the body alive in a sleeping state using a break through technology the other would be using a wormhole but we don't know of any in the moment

Biomolecules may be defined as the organic molecules that are present in the living organism. Four important biomolecules are proteins, carbohydrates, fats and nucleic acids.

The biomolecules are known as macromolecules because they are made of large units of molecule. The mRNA that translates to form a enzymes is macromolecule because RNA is made of large units of nucleotides. Lipid that found in cell membrane are macromolecules because they are made of more than 1000 atoms. Protein that are involved in DNA replication are macromolecules as they have large units of amino acids.

Korvikt [17]

Answer:

Null hypothesis: the behavior of mosquito larvae doesn't change in the presence/absence of predators added to the tanks in Treatments 2 and 3.

Explanation:

In statistics, the null hypothesis states that there are no differences between the two variables tested in the experiment, while the alternative hypothesis uses the experimental data in order to reject the null hypothesis. In this case, the alternative hypothesis will use the data from treatments 2 and 3 to confirm that predators can modify the behavior of mosquito larvae.

How does carbon dioxide travel in blood via dissolved form
alexandr1967 [171]

Answer:

carbon dioxide is more soluble in water than oxygen and hence is mostly transported in the dissolved form in our blood.

Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.

The majority of carbon dioxide is transported as part of the bicarbonate system.

Goodluck
