Answer:
An allele is a variant form of a gene.
The phenotype of the individual will always indicate with certainty the alleles of the individual
Explanation:
An allele is the alternate form of a gene example is allele A, allele a
While writing the genotype of an individual the allele is always seen, it usually written in pairs example is AA , Aa, aa, SS
The phenotype of an individual will reveal the allele such person have example is an individual with the sickle cell having allele s through the appearance of such individual one could know if such person posses the allele.
What kinds of characters can you use to create a data matrix for estimating phylogenetic trees?
a. any heritable trait.
b. any morphological trait.
c. any molecular trait.
d. any measurable trait.
Answer: The correct option is A
any heritable trait
Explanation:
This is because phylogenetic tree is a diagram that show or indicate the evolutionary relationships between several organisms from a descent or that have common anscetors which is based on the differences or similarities of there phenotypic traits or physically expressed inheritable traits.

Answer:
the nucleus
Explanation:
Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus.
True or False: Chromosomes can be seen with the naked eye.
the answer is false Because it is so thin, DNA cannot be seen by the naked eye unless its strands are released from the nuclei of the cells and allowed to clump together.
How might a sudden cold front limit population growth of newborn offspring?"" HELP PLEASE
Answer:
The correct answer is - they may not be able to survive at such a temperature.
Explanation:
A Cold front is a weather change when a cooler air mass moves into warmer air that leads to a sudden drop in temperature following by the cyclone, heavy rainfall and hail.
These sudden changes and heavy rain with storms and cyclones can limit the population growth of newborn offspring as they may not able to survive in such a sudden temperature drop.
Please read the following scenario to answer the following question. While working with cultured mouse cells, a researcher unknowingly treated the cells with a mutagen that causes the deletion or insertion of individual nucleotides in DNA. Subsequently, the researcher isolated and cultured a single cell from this group and noticed that the progeny of this cell were not producing a certain protein, and that this affected their survival. The mutation would be most harmful to the cells if it resulted in ________
Answer:
deletion or insertion of nucleotide from or in any coding sequence of the DNA
Explanation:
The mutation would be most harmful to the cells if it resulted in the deletion or insertion of nucleotide from or in any coding sequence of the DNA.
Deletion or insertion of a nucleotide from/into the coding sequence of DNA results in a frameshift mutation away from the original protein. Deletion/insertion of a nucleotide from/to the coding sequence of a DNA can cause a totally different protein to be synthesized from such DNA or, worse still, results in a nonfunctional protein. Both results could be grossly harmful to the cells.

The final paragraph of the CNN report said that "several eye specialists" had pointed out that the study should have accounted for heredity. Myopia is passed down from parents to children. Myopic parents are more likely to have myopic children, and may also be more likely to leave lights on habitually (since the parents have poor vision). In what way does the knowledge of this possible genetic link affect how we interpret the data from the study? Explain.
Answer:
Myopia is a phenotype that results from interactions between genetic factors and the environment
Explanation:
A quantitative trait is a polygenic trait that depends on the cumulative effects of many genes and the environment. Some examples of quantitative traits include weight and height. Myopia is a quantitative trait whose phenotype depends on the combined action of different genes and the environment. It has been shown that genetics plays a central role in this trait (myopia), it is for that reason that myopic parents are more likely to have myopic children. However, there also are environmental factors (e.g., diet) which increase the risk to suffer myopia.
Transcribe the following DNA strand. Then translate the tRNA strand you wrote.
Answer:
Transcription into mRNA strand will produce: ACU CAG CUG ACC GAC UGG CAU CUG
Translation into amino acid sequence will yield: Threonine- Glutamine- Leucine- Threonine- Aspartic acid- Tryptophan- Histidine- Leucine
Explanation:
- Transcription is the process by which DNA template is used to synthesize a mRNA molecule in the nucleus (eukaryotes). The transcription, which is carried out by an enzyme called RNA polymerase, follows the complementary base pairing rule i.e. A-T, G-C. Note that Uracil replaces Thymine in the RNA molecule.
Based on this question in which a DNA strand was given as follows: TGA GTC GAC TGG CTG ACC GTA GAC
The mRNA strand that will result from transcribing this DNA will be: ACU CAG CUG ACC GAC UGG CAU CUG
- Translation is the process by which mRNA strand is used to synthesize amino acid sequence (protein) in the ribosomes. In the mRNA sequence, nucleotides are read in a group of three called CODONS. Each codon specifies an amino acid. Based on the mRNA sequence as follows: ACU CAG CUG ACC GAC UGG CAU CUG, the amino acid sequence that will result after using the genetic code will be: Threonine (Thr)- Glutamine (Gln)- Leucine (Leu)- Threonine (Thr)- Aspartic acid (Asp)- Tryptophan (Try)- Histidine (His)- Leucine (Leu).

the cell cycle in the proper
order:
a. Anaphase
b. Cytokinesis
C. G2
d. Telophase
e. G1
f. Prophase
8. S
h. Metaphase
The cell cycle in the correct order is G1, S, G2, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.
What is the cell cycle?Prophase, metaphase, anaphase, and telophase are the four phases that a cell goes through. To form chromosomes, chromatin condenses (sister chromatids joined at the centromere).
In prophase, the chromosomes get shorter and thicker, in the center of the cell, during the metaphase, the chromosomes align. Chromatids separate during the anaphase process and travel to the opposing poles.
Telophase: Two nuclei are produced when nuclear envelopes have reformed around each chromosomal group.
Therefore, the cell spends the majority of its time in interphase, which is also when it grows, duplicates its chromosomes, and gets ready to divide.

when you move your hand up and down while holding on a jump rope, you make a wave. What is the medium
Answer:
The medium of the wave is the Rope.
Explanation:
This is because it is transverse wave and transverse wave need a medium to transfer energy and this is because in transverse wave,particles of the medium move in a direction that is perpendicular to the direction of the transverse wave. From the question, when you move you hand up and down, you make a wave and the direction of the wave is also up and down which is perpendicular to the direction of the wave.
What do we still need to know in order to determine why the two rock formations have such similar minerals?
Answer and Explanation:
Rock is defined as the collection of one or more minerals. Granite, sedimentary rock, igneous rock, metamorphic rock and limestone are the types of rock. Granite is the most common type of rock. Granite is made up of four minerals such as hornblende, feldspar, quartz and mica. Granite breaks down to form sedimentary rocks. Igneous rock begins as magma. The lava and magma harden to form igneous rock. Metamorphic rocks are made from pressure. Rocks are made of one or more minerals, which are cooled and melted together, cemented together, or heated and squeezed together. The mineral occurs naturally and is made of crystals. The earth’s crust is made of rocks. Most rocks are covered by soil. Soil contains the small pieces of rocks. The two rocks have similar composition but different texture. Rocks are formed in different ways. The rocks can be changed from one form to another.

A. Paper reduction
B. Slash and burn
C. Recycling
D. Reforestation
Answer:
D. Reforestation
Explanation:
Reforestation is a natural or intentional way of restoring existing forests and woodlands by restocking it after they have been depleted through deforestation. Forest industry makes use of forest product for production this includes log, paper and pulp production. Ability to restock after felling of this tree for product making helps continuation.
Reforestation helps to rectify the effects of deforestation and this helps to improve our health in turn by absorbing pollution and dust from the air.

a. Genotype YyRr, if Y and R are on different chromosomes
b. Genotype YyRr, if dominant Y and R are on the same chromosome, no crossing over
c. Genotype YyRr, if dominant Y and recessive r are on the same chromosome, no crossing over
d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over
Answer:
The correct answer would be -
1- YR, Yr, yR and yr.
2. Yr, yR
3. YR, yr
4. YR, Yr, yR & yr
Explanation:
A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.
The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.
1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.
2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.
3). if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.
4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.

m. blood
n. esophagus
Answer:
Mouth -Esophagus-- Stomach -Duodenum -Jejunum -Brush border disaccharidases--Glucose transporters--Active transport--Blood-Glycolysis-Pyruvate--Citric acid cycle - Carbon dioxide and water : )
Explanation:
The journey of a glucose molecule from the mouth and ultimately to the muscle cells for energy in the correct order is:
Mouth > Esophagus > Stomach > Duodenum > Jejunum > Brush Border Disaccharidases > Blood > Glucose Transporters > Glycolysis > Pyruvate > Citric Acid Cycle > CO2 and Water > Active Transport > Electron Transport System.
The drink rich with disaccharides starts its journey from the mouth cavity and moves through the esophagus to the stomach. The disaccharide digestion takes place when it reaches the jejunum through the duodenum of the small intestine by enzyme maltase that also presents in Brush Border Disaccharidases to glucose.
Glucose moves o blood and through a glucose transporter for cellular respiration that starts with glycolysis that converts glucose to pyruvate and enters in TCA cycle and releases CO2 and water as byproducts that ultimately moves to the ETS system to provide energy to the muscles.
Thus, the correct answer is - given above in the correct order.
