2)The two things that make archaebacteria difficult to study are that archaebacteria lived only in these extreme environments and that we don't know how to feed them for studying them
3) Protista is the most heterogeneous kingdom in terms of morphology
4) The difference between kingdom and domain is that the kingdom is one of the five major groups of living organisms while the domain is one of the three taxonomic categories of living organisms above the kingdom level.

Calcium-41 has a half-life of 80,000 years. At the end of 240,000 years,
how much Calcium-41 would remain in a sample initially containing 60
micrograms? *
A 7.5 micrograms
B 60 micrograms
C 15 micrograms
D 30 micrograms

Answers

If the half-life is 80,000 years, then 240,000 years would be equivalent to three half-lives. In other words, the initial amount of the radioactive calcium-41 would have been reduced in half three times over. Mathematically, this can expressed as

calcium-41 remaining = initial mass of calcium-41 × (0.5)³.

Since we are given the initial mass of calcium-41, the amount of calcium-41 remaining after 240,000 years would be:

60 μg × (0.5)³ = 7.5 μg, or 7.5 micrograms.

7.5 is the answer I think hope this helps

To make ethanol for use in _______, yeast is provided with sugars that have come from crops such as maize.

Answers

Answer: To make ethanol for use in BIOETHANOL( a biofuel), yeast is provided with sugars that have come from crops such as maize.

Explanation:

Ethanol Fermentation is defined as the process whereby sugar( fructose, sucrose or glucose) are broken down by the action of microorganism such as yeast to give of ethanol(alcohol) and carbondioxide as by products.

In the use of ethanol as a biofuel, there are different sources where sugar products can be gotten from, but the main sources of sugar required to produce ethanol come from energy crops. These crops are grown specifically for energy use and include corn, maize and wheat crops.

BIOETHANOL is a renewable source of fuel that can be produced through the yeast fermentation of sugar gotten from crops such as maize. Although ethanol can be used in wine and beer production, sugar sources are usually gotten from grape fruits and barley.

Which type of mutation often has the least effect on organisms' traits (and may have no effect at all)? Nondisjunction Substitution Insertion Deletion

Answers

Answer:

The correct answer is - substitution.

Explanation:

Substitution mutations are the point mutations that are the mutations that least likely affect the trait of an organism or have no effect at all. Substitution mutations take place when there is only one nucleotide base is substituted by another nucleotide base in the  DNA or RNA of an organism's genome.

In this case, there is no effect found on the protein formed by these DNA sequences. These substitution mutations generally found in somatic cells and have little to no effect at all.

If you assume that the high projection is correct, what is one way the larger
human population can ensure it has enough food?

Answers

Planting fruit and vegetables

The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops. Therefore, the correct option is option B.

What is population?

The term "population" is frequently used to describe the total number of people living in a particular location. To estimate the number of the residents within a certain territory, governments conduct censuses. The phrase has particular use in the domains of ecology and genetics and is also used to refer to plants, animals, and microbes.

An region with a sexual populace is one in which interbreeding between any two individuals therein is both conceivable and more likely than cross-breeding between individuals from other places. The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops.

Therefore, the correct option is option B.
