Arturo ran a 3,000-meter race. His running time from start to finish was 10 minutes. What was Arturo's average speed?
Answer:
300 meters/min
Explanation:
average speed = distance / time
(3000 m) / (10 min) = 300 meter per minute
if you need it in meters/sec then just multiply 10 by 60 first and then continue
(3000 m) / (600 sec) = 5 m/s

Why are planets round?
*
A.Gravity pulls mass in one direction
B.Gravity pushes mass out from the center
C.Gravity pulls mass into its core from all directions equally
D.Elliptical orbits smooth out planetary imperfections
Answer:
c
Explanation:
planets are round because of their gravitational field acts as though it pulls everything from the center of its body and pulls everything toward it
Which section of the article BEST explains why the development of CRISPR-Cas9 is significant for the scientific community?
Answer:
It allows the scientists to activate gene expression instead of cutting the DNA.
Explanation:
The development of CRISPR-Cas9 is significant for the scientific community because this development allows the scientists to activate gene expression instead of cutting the DNA. This technique allows the scientists and researchers to study the function of the gene. Before development, Cas9 enzymes produced by the CRISPR system binds to the DNA and cuts it by shutting the targeted gene off so this development of CRISPR-Cas9 enables the scientists to activate gene expression instead of cutting the DNA.
Why do scientists that work on producing biofuel from algae need to understand algal reproduction?
Answer:
Due to more production of biofuel.
Explanation:
Scientists that work on producing biofuel from algae need to understand algal reproduction because reproduction of algae is responsible for the higher productivity of biofuel. Algae produce by both sexually and asexually means from the fusion of male and female gametes and from only one parent. Algae needs carbondioxide gas and light for the growth and reproduction so if these factors are present in sufficient amount then the algae increases in growth and reproduce rapidly which leads to higher production of biofuel.
Fuels acquired from biomass is called biofuel. Biomass can be a plant, animal waste or algae. It is a reservoir of renewable energy and can be supplied readily.
Scientists operating on biofuel need to learn about algal reproduction as algae is the major source of biofuel production.The potency of biofuel depends on the generative cycle of the algae.Algae can propagate asexually by means of spores and vegetatively or through sexually by producing the gametes.If the determinants like carbon dioxide and sunlight required for reproduction are present in the right quantity then the algae will thrive and proliferate rapidly, thus increasing biofuel production.Therefore for increasing biofuel production, we need to know the reproductive methods of algae.

If you have a hamster with long fur, what possible genotypes could the hamster have?
Answer:
Ll, Ll, LL
Explanation:
So, there is one thing we must remember to answer this:
1# dominant genes(long fur) are expressed over reccesive genes(short fur)
Knownign that dominant is over reccesive, it is simple. If the genotype was Ll or lL then the dominant long fur would be expressed over reccesive short fur. Long fur - Ll, lL
Next, we know that LL will be long fur since its both long and long, and there is no possibility for short fur. Long fur - LL
Finally. we have ll, and since there isnt a dominant long fur, and only reccesvie short, then this cannot be long fur. Short fur. - ll
Where are spores produced in a fungus? Please give a explanation on the process of how these spores are produced and then sent out of the fungus for distrubution?

Answer: it's the second one
Explanation:
if there are lots of animals who eat grass then there will be very few producers (which are those plants + grass). Hope this helps!

Which conclusion is supported by the fact that the black-breed boar, with its quality meat, and the white-breed sow, with its quality fertility, are swine that are often matched for mating? Animals are often paired based on physical traits and personal compatibility. Strong reproductive capability is the most important trait in animal breeding. Selective breeding combines ideal traits of animals to replicate in offspring. Swine are the only agricultural animal species that are currently crossbred.
Answer:
Selective breeding combines ideal traits of animals to replicate in offspring
Explanation:
Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.
In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.
