Answer: b. photosynthesis.
Explanation:
Photosynthesis is a chemical reaction that occurs in the cells of the plant leaves. The process requires carbon dioxide from the atmosphere and water as reactants. These reactants get converted into carbohydrates (glucose) and oxygen as byproducts in the presence of sunlight. For the first time on earth the oxygen was produced by the photosynthesizing cyanobacteria. As these organisms used to fix carbon dioxide in water.
Therefore, oxygen was introduced into the atmosphere as a byproduct by the process of photosynthesis.
Blocking would be best used 'by blocking on chicken type'. This means conducting separate trials for different types of chickens while testing the chicken feed because the type of chicken was determined to impact egg production.
In a scientific experiment where the aim is to conclude whether a certain chicken feed leads to higher egg production, blocking would be used to control the variables that might affect the result of the experiment. According to the information given, chicken's water intake is said to have negligible influence on egg production, however, the type of chicken does impact the production quantities.
Therefore, the ideal way to apply blocking to the experiment would be by differentiating the groups of chickens based on their type; this method is referred to as blocking on chicken type. The implication of this is, testing different chicken feeds on different types of chickens separately to ensure the accuracy of the experiment results by eliminating confounding factors.

What’s the mRNA sequence?
What will be the amino acid sequence?
Will there likely be effects?
What kind of mutation is this?
mRNA Sequence: AUGUGGAACCGUGACU
Amino Acid Sequence: Methionine-Tryptophan-Asparagine-Arginine-Cysteine.
Likely Effects: Minimal impact, as the mutation is a silent mutation, not changing the amino acid.
Mutation Type: Point Mutation.
To find the mRNA sequence, we need to perform transcription, where DNA is used as a template to synthesize complementary mRNA. In this case, we have a substitution mutation in the DNA sequence, so the mRNA sequence will also be affected.
Original DNA Sequence: T A C A C C T T G G C G A C G A C T
Mutated DNA Sequence #5: T A C A C C T T G G G A C G A C T
The mRNA sequence is formed by replacing T with U (uracil) in the DNA sequence:
Original mRNA Sequence: A U G U G G A A C C G C U G C U G A
Now, let's determine the amino acid sequence using the mRNA sequence. Amino acids are coded by codons (three-letter sequences). Here's the mRNA sequence grouped into codons:
AUG UGG AAC CGC UGC UGA
The codons code for specific amino acids:
AUG: Methionine (start codon)
UGG: Tryptophan
AAC: Asparagine
CGC: Arginine
UGC: Cysteine
UGA: Stop codon
So, the amino acid sequence is Methionine-Tryptophan-Asparagine-Arginine-Cysteine.
As for potential effects, the mutation seems to result in a single amino acid change (from glycine to asparagine). Whether this has significant effects on the protein's function depends on its role. If the protein is critical for an essential function, even a single amino acid change can have noticeable effects. However, if it's a less crucial protein or a non-coding region, the impact may be minimal.
This mutation is a point mutation, specifically a missense mutation, where one nucleotide is substituted with another, leading to an amino acid change in the resulting protein.

Explanation:
The Earth layer composed of liquid iron and nickel is the Outer Core. This is the third layer from the surface and its fluid motion creates Earth's magnetic field.
The layer of the Earth which is primarily composed of liquid iron and nickel is the Outer Core. The Earth can be divided into four main layers: the crust, the mantle, the outer core, and the inner core. The Outer Core, which is the third layer of the Earth if you start from the surface, is a sea of mostly molten iron and nickel. This liquid layer is about 2200 kilometers (1367 miles) thick and creates the Earth's magnetic field due to the movement within it.

Answer:
An increase in the number of invasive species leads to a decrease in the diversity index. This species can alter the food web within an ecosystem by eliminating the local food sources leaving no food for the faunas. If plant diversity declines, the habitat would definitely lose its balance. The ecosystem would lose its balance. Plants are considered producers and are always the beginning of the food chain. Without plants, animals that consume plants will definitely decline it number; thus, also the consumers on top of the chain.
Explanation:
Joe is at a higher altitude than if he was at the beach.
The air Joe is breathing is less dense than the air at sea level.
The air pressure is higher where Joe is than where Dave is.
If Joe keeps going up, air pressure will continue to decrease.
The air Joe is breathing is denser than the air Dave is breathing.
Answer:
Joe is at a higher altitude than if he was at the beach.
The air Joe is breathing is less dense than the air at sea level.
If Joe keeps going up, air pressure will continue to decrease.
Explanation:
Joe stands at the top of a hill on a trail above the ocean which represents a higher altitude when compared to the beach level.
At higher altitudes the air is usually less dense.
As altitude increases the air pressure decreases.
