Answer:
I think that limestone is older
Explanation:
Evaluate the examples and select those that do not show artificial selection.
A. White rabbits have a low survival rate in nature, because it is easy for predators to spot them.
B. Penguins with higher body fat tend to survive nesting in the Antarctic winter, while leaner penguins often die.
C. A gene for disease resistance in fir trees is transferred to pine trees using modern DNA technology, allowing farmers to maximize pine tree growth.
D. Because big game hunters sought elephants for ivory, often poaching those with the biggest tusks, more African elephants today naturally lack tusks compared to the elephant populations 100 years ago.
E. In subsaharan Africa, genetically modified grass varieties that carry genes for disease and drought resistance are now available to farmers, providing more sustainable food sources for their livestock.

Answer:
Grabbing a handful of mixed candy out of a bowl.
Explanation:
For all other options you are choosing specific items... such as a book from the library, or choosing items written on your grocery list, or choosing what to pack for lunch. Bycatch in fishing refers to catching extra fish, other than what you are selecting for. By grabbing a handful of mixed candy from a bowl you are not selecting for a specific 'fish'.

If an animal has 21 chromosomes before replication, how many do they have after?
Answer:
Animals usually have 22 pairs of homolog chromosomes (autosomes) and as sex chromosomes 2 x chromosomes (in female), or 1 x and 1 y chromosome (in males), thus in total 46 chromosomes per body cell (see human karyogram; 2n = 46) and 92 chromatids per cell after replication.

Each fragment generated during the cycle sequence reaction is labeled with:
A. All four colors of fluorescent dye throughout the length of the fragment
B. All four colors of fluorescent dyes at one end of the fragment
C. One color of fluorescent dye at one end of the fragment
D. One color of fluorescent dye throughout the length of the fragment
Answer:
C
Explanation:
In cycle sequencing technique, four distinctive fluorescently named dideoxyNTPs are utilized ( ddATP, ddGTP, ddCTP and ddTTP) notwithstanding ordinary dNTPs. each ddNTP marked with an alternate fluorescent color. Toward the finish of the experiment, the outcome yields various pieces of variable lengths each resulting in a solitary terminal fluorescent ddNTP towards the end.

A woman and her baby are on a TV talk show to determine whether or not a particular man is the father of the child. Mom is blood type O and the baby is blood type B. The potential dad is blood type A. Is it true or false that he is the father?
Answer:
No that is not the father
Explanation:
The fathers blood would have to be type B. Type A is dominate to O and co-dominate to B so you get AB blood, type B blood is dominate to O blood. So if the mom has to be OO to show O blood and the father has to be AA blood because he isn't AB or AO, which could make the baby AO or OO blood. Since none of this is true the "TRUE" father would have to have AB, BB, or Bo blood.
In people-eaters, purple is dominant to white. A true-breeding white mutant is mated with a different true-breeding white mutant. All of the F1 are purple. When the purple F1 offspring mate with each other, their offspring occur in the ratio of 9 purple : 7 white. Which phenomenon explains the purple F1 offspring
Answer:
The correct answer is - Complementation.
Explanation:
In this pattern of inheritance, there are two same type mutants that are crossed that are true-breeding white with another true-breeding white mutant. Let these mutants are CCpp and the other be ccPP.
All the f1 offspring produced are found to be purple in color as offspring will be CcPp. The products of both gene C and P required for the purple pigment to be expressed these genes complement each other and the absence of any of gene results in lack of the dominant phenotype.
9. Which nucleus has role in conjugation in Paramecium
a) Mega nucleus
b) Micronucleus
c) Macronucleus
d) Cellular nucleus
( b ) Micronucleus has role in conjugation in paramecium.
The organism's germ line genetic material is kept in the micronucleus. It is in charge of the genetic rearrangement that takes place during conjugation and generates the macronucleus (cross-fertilization). Thus option B is correct.
What Micronucleus role in conjugation in Paramecium?The pairing and subsequent fusion of two paramecia is a process known as conjugation. It is known as a cytoplasmic bridge where they converge. After meiosis, the diploid micronucleus divides into four new micronuclei. The micronuclei of the cell, all except one, break down.
This method doesn't include meiosis or nuclear fusion. It manifests in a single person in the manner described below: Macronucleus deteriorates and vanishes. Eight nuclei are produced after the two micronuclei divide twice through mitosis.
Therefore, Micronucleus has a role in conjugation in Paramecium.

Given the following sequence of DNA, write the correct sequence of complementary DNA bases.
TACCGATAA
Given the following sequence of DNA, write the correct sequence of complementary mRNA.
ACCGTACTG
Given the following sequence of DNA write the correct sequence of amino acids.
ATAGGCGTA
Answer:
1. ATGGCTATT
2. UGGCAUGAC
3. mRNA: UAU-CCG-CAU, amino acids: tyrosine(tyr)-proline(pro)-histidine(his)
Explanation:
For DNA, the complementary bases are T=A and C=G. This means every time you see one of these letters, the corresponding letter goes with it. For mRNA, the bases are T=A, A=U, C=G. It is the same except now, there should be no "T" in the mRNA sequence. With amino acids, you would first code for the mRNA sequence, every three letters being the amino acid sequence. To find the amino acid, you would look at a codon chart unless your teacher wants you to memorize them. The first three letters of the amino acid are the abbreviation.

d) During Transcription, a nucleotide has been deleted. Explain the effect this will have
on DNA as well as what happens in each step along the way to a protein.
Answer:
this mutation may change the open reading frame of the resulting RNA sequence and its final product, which is a protein in the case that this gene is used to synthesize a messenger RNA (mRNA) sequence
Explanation:
During the transcription, a region of DNA named 'gene' is used as template to produce an RNA molecule, typically a primary transcript of mRNA (pre-mRNA). Subsequently, this pre-mRNA suffers a process named RNA processing in order to generate a mature mRNA which is finally used to create a protein by a process called translation. If a deletion occurs during transcription, it may change the open reading frame (ORF) of the resulting mRNA when the mutation occurs in an exon of the protein-coding gene (i.e., occurs a frameshift mutation), while this deletion may not have any effect if it is localized within the introns which are removed during RNA processing. A frameshift mutation will change the amino acids that are added to the nascent polypeptide chain during translation.

Explanation:
1. The materials are physically combined because all of the materials including the sand, salt, and iron fillings are their own substances and they maintain their original form. This is a mixture and they aren't chemically combined.
2. To separate each of the materials physical means would be used because since they're their own individual substances and have kept their original form they're mixed and not chemically combined.
3. The iron and oxygen atoms in rust are chemically combined because they are no longer individual substances and haven't kept their original form, so therefore they're a chemical combination.
