What are two genotypes that could produce a dominant phenotype?
Answer:
A homo-zygous dominant genotype and a heterozygous genotype
Explanation:
A homo-zygous dominant genotype refers to a genotype that contains two copies of the dominant gene variant, i.e., two dominant alleles at its locus, thereby individuals carrying this genotype will show a dominant phenotype. Moreover, a heterozygous genotype is a genotype that contains both dominant and recessive alleles at its locus. In a heterozygous genotype, the dominant allele is always expressed and masks the recessive allele, thereby showing a dominant phenotype.

___ of the greenhouse effect is a bad thing. Since there are more and more greenhouse gases in the atmosphere more ___ is trapped which make the earth ___. This is called ___
Answer:
1. Increase/occurrence
2. Heat
3. Warm
4. Global warming
Explanation:
Greenhouse effect is the process whereby heat is trapped by certain gases in the atmosphere called GREENHOUSE GASES e.g. carbon dioxide (CO2). Greenhouse gases have the ability to trap heat, hence, their increase in the atmosphere becomes a major concern as it starts becoming a bad occurrence.
An increase in the greenhouse gases in the atmosphere means more heat will be trapped, thereby, inducing the Earth to become WARM. This process where the Earth's temperature rises as a result of greenhouse effect is called GLOBAL WARMING.
Which structure helps fish remove oxygen from the surrounding water?
Answer:
Gills
Explanation:
In order to remove oxygen from the water, they rely on special organs called "gills." Gills are feathery organs full of blood vessels. A fish breathes by taking water into its mouth and forcing it out through the gill passages.

Look at Scenario A below and select the correct Punnett Square that corresponds with the scenario. For all questions, the trait being studied is seed color - red seeds (R, dominant) and pink seeds (r, recessive). Scenario A: Parent 1: heterozygous Parent 2: pink
Answer: A
Explanation:
Heterozygous means it has both a recessive and a dominate allele so in this case it’d be shown as Rr. For a parent to appear pink, the genotype must be rr (because r is recessive and won’t show up in the parent if there’s a dominant allele to over lower it). The only option that shows an Rr and rr pairing is option A

How does seed formation take place in plant? explain.
Answer:
Seeds are the result of plant reproduction. ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.
Explanation:
Please place the following (Protein Synthesis) steps in the right order:
Protein Synthesis Steps:
mRNA carries the newly copied code out of the nucleus and to the ribosome.
The proteins get to work!
RNA nucleotides pair up with their corresponding DNA bases, copying the code.
tRNA brings the appropriate amino acids to the ribosome depending on the code.
A series of amino acids make up the newly formed proteins.
DNA unzips exposing nitrogen bases.

Explanation:
Predation- Predator hunting prey Ex: lions hunting gazelle
Parasitic- One organism benefits while the other is harmed Ex: Lice eating Hair
Competition- Organisms fighting over reasources Ex: Hippos fighting for space
Symbiosis- Two unalike organisms form a bond where they both benefit Ex: Birds eating ticks off buffalo.
Mutualism- Two organisms benefit from each other Ex: whale shark getting cleaned by remora fish which get a meal.

Which of the following correctly describes the structure of tRNA?
A. 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Disulfide bonds
B. 3 base codon one the bottom, Amino acid attachment site on top, phosphate groups on the left and right sides
C.3 base codon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
D. 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
Answer:
the answer is D 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
Explanation:
idfk know man, but thats the answer!
The option that correctly describes the tRNA's structure is D. 3 base anticodon one the bottom, Amino acid attachment site on top, held together by Hydrogen bonds
tRNA stands for transfer ribonucleic acid. It interacts with the mRNA and aminoacids being a key element in protein synthesis.
The tRNA structure is:
Three base anticodon, one on the tRNA's bottom. They are three nucleotides that interact with a complementary mRNA codon. An amino acid attachment site on top where the specific amino acid for the anticodon attaches, later on, in the ribosome, together with the codon in the mRNA it adds the amino acid to the forming protein.Hydrogen bonds between tARN bases. These bonds give the tRNA its characteristic shape.In conclusion, the tRNA structure is anticodons, an amino acid attachment site on top, and hydrogen bonds between the bases.

PLEASE I NEED HELP ASAP!! WILL GIVE BRAINLIEST AND 100 POINTS!!! When you cross two heterozygous organisms, what is the probability that the offspring will show the dominant phenotype? (HINT: You may want to draw a Punnett Square on a separate piece of paper to help.)
A. 100
B. 75
C. 50
D. 25
E. 0
Answer
75% chance
Explanation:
The dominant and recessive are the terms used to explain the phenotypic traits and genetic makeup of an organism. The cross between a heterozygous species will result in a 75% chance of the species expressing a dominant phenotype.
The correct answer is:
Option B. 75%
The heterozygous condition refers to the one dominant and one recessive allele, whereas purebred is the condition in which both alleles are either recessive or dominant.
The dominant alleles are always expressed in purebred and heterozygous conditions.
The recessive alleles are expressed in purebred conditions only.
In the given attachment, consider the cross between round shaped-seeds in heterozygous conditions.
Thus, the chance of progeny will have round-shaped seeds is 75%.

Explanation:
If 30% of a DNA sample is composed of thymine nucleotides, what percentage of the DNA sample would be composed of cytosine nucleotides?
Answer:
20%
Explanation:
Pairing do occur between a purine and a pyrimidine base or a pyrimidine and a purine base where Adenine pairs with Thymine and Guanine pairs with Cytosine.
DNA(deoxyribonucliec acid) sample is usually compose of 100% nucleotide base,
Since 30% of the sample section is compose of thymine then Adenine the base pair will also be 30% this is because adenine will always pair with thymine and each will occur in equal quantity. Together, adenine and thymine compose 60% of the segment.
While the remaining 40% of the section is composed of guanine and cytosine pairs and since the two bases will be equal in quantity, 20% of the DNA section will be cytosine nucleotide.
