Place the rock layers in order from oldest to youngest in the blanks below. Type the letters as they
are shown.
Answer:
C
Explanation:
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.

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.

a) to compare the food chains of each ecosystem
b) to convince the reader to protect the environment
c) to explain what keystone species are important in each ecosystem
Answer: to explain what keystone species are important in each ecosystem
Explanation:
The overall theme of the article is to explain what keystone species are important in each ecosystem.
Keystone species is referred to as an organism that defines the ecosystem as a whole. They help define the habitat's biodiversity.
It should be noted that despite the fact that every living organisms depends on each other, some species are more vital than others and when they're removed, there will be a drastic change in the habitat.

State one way by which Carbon Dioxide increases in the atmosphere
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
Answer:
pollution is the way by which carbon dioxide increases

If photosynthesizing green algae are provided with CO2 containing heavy oxygen (18O), later analysis will show that all of the following molecules produced by the algae contain 18O except If photosynthesizing green algae are provided with CO2 containing heavy oxygen (18O), later analysis will show that all of the following molecules produced by the algae contain 18O except ribulose bisphosphate (RuBP). O2. 3-phosphoglycerate. glucose. glyceraldehyde 3-phosphate (G3P).
Answer:
Option B, O2
Explanation:
It is because the oxygen released during the process of photosynthesis comes from the water absorbed by the roots and not by the CO2containing heavy oxygen (18O). In fact oxygen from CO2 containing heavy oxygen (18O) is used in making sugar which is then stored for energy.
Hence, option B is correct

Which process of genetic recombination involves genes from both parents?
crossing over
independent assortment
fertilization
tetrad formation
Answer:fertilization
Explanation:
The process of genetic recombination which involves genes from both parents is crossing over. This process occurs during prophase I of meiosis, when homologous chromosomes pair up and exchange genetic material.
Explain the process?A portion of each parent's chromosome is swapped during this process, resulting in two new chromosomal combinations that are distinct from those of either parent. Genetic variety among the progeny is produced as a result of this process, which is advantageous for evolution.
The process of crossing over is random, therefore it is unpredictable which chromosomal segments will be exchanged. This is crucial for fostering genetic diversity because it allows for a wider variety of genetic combinations to be produced when genetic material is exchanged.
As portions of each chromosome will be exchanged during crossing over, this procedure also aids in ensuring that the offspring obtain a combination of genetic material from both parents.

Write the CODON that corresponds with each amino acid. There may be more than one. The full names are written, but the codon chart only shows the first three letters. proline ______________________ glycine ______________________ valine ______________________ phenylalanine ______________________ histidine ______________________ arginine _________________
Answer:
In protein synthesis, different mRNA codons produce different amino acids by the translation process with the help of ribosomes and tRNA. These mRNA sequences are read in sets of three which are termed as triplet codons. Specific amino acids are produced by different codons, however, more than one codons code for one amino acid. The given amino acids correspond with the following codons:
Proline: it corresponds with four codons

Answer:
Explanation:
Dr Mrs Brown has now antigen on her red blood cells because Blood type Of are often refer to null because it has neither antigen A or B. Therefore it is null.
But blood type Of normally have both A and B antibodies in the blood cells.
What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
