6. What is the name of the mutation in which a base is added to the
genetic sequence?
shift
Answer: frameshift mutation
Explanation: A frameshift mutation is a particular type of mutation that involves either insertion or deletion of extra bases of DNA. Now, what's important here is the number three. The number of bases that are either added or subtracted can't be divisible by three.

multicellular life appeared about 1 billion years ago name the eon that corresponds to this
Answer:
The Proterozoic Eon
Explanation:
The eons are the longest periods of geologic time. The Proterozoic eon is the geological eon from the appearance of oxygen in the atmosphere until the emergence of complex life forms (e.g., marine invertebrates). The Proterozoic eon started about 2.5 billion years ago and ended 541 million years ago. This eon can be divided into three geologic eras: Paleoproterozoic (2,500 to 1,600 million years), Mesoproterozoic (1,600 to 1,000 million years) and Neoproterozoic (1,000 million to 541 million years).

Explanation:
why the concentration of nitrate ion in the soil had decreased after the farmer grew maize plants in the field?
Answer:
because the maize plant will take in the nitrate and use it to make proteins for growth.
The concentration of nitrate ion (nitrogen) in the soil decreases after the farmer plants maize plants in the field because the maize plants have taken up these ions.
Does maize require nitrogen?To develop and produce, maize plants need a lot of nitrogen. 160 kg/ha of nitrogen are removed on average by maize crops.
What purpose does nitrogen serve in maize?Due to its function in photosynthesis and other biological activities like mineral and water absorption, vacuole storage, and xylem movement, nitrogen is a crucial nutrient for maize and a major regulator of grain output.
What type of fertilizer is ideal for maize?The growth, yield, and quality of maize crops are most strongly influenced by nitrogen.
Fertilizer with nitrogen is necessary for healthy leaf growth.
What happens if the leaves of maize are small?Less photosynthesis, which is necessary to store starch in grains, occurs as a result of smaller leaves.

Need help I will give you 20 points plsss
Answer:
III3 will be "pp" lower case p
II2 will be Pp
Explanation:
As we know the trait is caused by dominant alleles. III3 is not affected so she will have two recessice alleles so 2 lower case p.
III2 is affected so the person will have one dominant allele P and one recessive. The dominant is from the father and the recessive is from the mother.
Hope that helps
Answer:
1. pp 2. Pp
Explanation:
1. Since it says the genetic disorder is caused by a dominant allele, that means that the ones affected (colored in) would have one "P" allele. Those not affected (not colored in) would display the genotype "pp." That would mean that generation III-3's genotype would be "pp."
2. The genotype of III-2 is "Pp." The dad was not affected (meaning he has 2 recessive alleles, pp) and the mom was affected (meaning she has at least 1 dominant allele, p; her genotype would either be PP or Pp). Because of this, III-2 would have to get one allele from the dad and one allele from the mom, therefore... their genotype would be: Pp.

9. If your goal is to produce white butterflies, is it faster to wait for natural
selection to take place or to use artificial selection? Why?
Answer:
Artifical selection would be much quicker because you can breed specific butterflies to get your desired result. Natural selection may produce undesirable results, this is because you cannot choose which butterflies to breed. So you may end up with other coloured butterflies instead.
How do mammals compare with birds and reptiles in terms of temperature regulation and structure of the heart?
Answer:
the biggest difference is that mammals are endothermic and internally regulate their body temperature, but reptiles are ectothermic because they rely on the environment to do it for them.
Explanation:
Ectothermic: An ectothermic animal, also commonly known as a "cold-blooded" animal, is one who cannot regulate its own body temperature, so its body temperature fluctuates according to its surroundings. The term ectotherm comes from the Greek ektos, meaning outside, and thermos, which means heat
Endothermic: An endothermic process is any process with an increase in the enthalpy H of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
Exothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. Endothermic reactions takes in energy and the temperature of the surroundings decreases.

Answer:
fats and oils.
Explanation:
You may wonder how the heck a large animal like a cow gets any energy from grass. The answer lies in these microbes. As they digest the cellulose by way of fermentation, their metabolic pathways produce chemicals called volatile fatty acids (VFAs) or fat sources (oilseeds, animal, and vegetable oils).

Don't copy from the internet, If you do, Summarize it into an answer no longer than 2-3 sentences and make it your own words
BIG BRAIN ANSWER:
Before Darwin, a naturalist named Jean-Babtiste Lamarck believed that the environment altered the shape of individuals and that these acquired changes were then inherited. Meanwhile, Charles Darwin was a naturalist on a ship called the HMS Beagle, and he discovered that the beak shape varies among finch species in the Galapagos Islands. He found that the beak of an ancestral species of finch had somehow been transported to these islands, and adapted over time to acquire different food sources that were available, causing variation, and that nature just selected for the most suitable beak shape and against less useful ones.
