Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experamint did he perform to test this idea
Answer: He performed dihybrid crosses
Explanation:
Dihybrid cross is simply refered to as a cross that is done for two genes that are different with regards to their traits. For example, if we cross two maize plants which have different shapes and color let's say that one is white and round while the other maize's colour is yellow and its shape is wrinkly.
Since Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another, the experiment performed will be dihybrid crosses.

Which of the following occurs in lactic acid fermentation?
a. Electrons pass through the electron transport chain.
b. Oxygen is consumed.
c. Lactic acid is converted into pyruvic acid.
d. NAD+ is regenerated for use in glycolysis.
Answer:
D
Explanation:
Thats all i know hope it helps
Lactic acid is created when pyruvate is reduced to make it, while NAD+ is created when NADH is oxidized. Reducing pyruvate to lactate requires a proton from NADH and electrons from the molecule. Thus, option D is correct.
What is the role of Lactic acid fermentation?Anaerobic respiration occurs when human muscle cells do not receive enough oxygen. So, the fermentation of lactic acid results in the production of energy molecules. The result of this process is lactic acid.
Oxidize electron transporters to allow for glycolysis re-use. Without the aid of oxygen, fermentation enables cells to generate chemical energy from the breakdown of sugar, such as glucose.
Therefore, in lactic acid fermentation, NAD+ is regenerated for use in glycolysis.

Does DNA in animals and plants use the same nitrogenous base pairs?
Answer: There are pretty obvious differences between plants and animals, but – at the chemical level – the cells of all plants and all animals contain DNA in the same shape – the famous “double helix” that looks like a twisted ladder. What’s more, all DNA molecules – in both plants and animals – are made from the same four chemical building blocks – called nucleotides.

why CO2 still being produced for a few minutes after death?
Explanation:
As best as anyone can gauge, cell metabolism likely continues for roughly four to 10 minutes after death, depending on the ambient temperature around the body.
During this time period, oxygenated blood, which normally exchanges carbon dioxide with oxygen, is not circulating. Thus, cell respiration—which uses oxygen to make cellular energy while creating carbon dioxide as a by-product—creates carbon dioxide that is not transported out of the cell. This lowers the pH of the cell, resulting in an acidic intracellular environment. This acidic environment causes intracellular membranes to rupture—including those around the cell's lysosome, which contains enzymes for digesting everything from proteins to fats and nucleic acids. Once the membranes have burst, these enzymes are released and begin to digest the cell from the inside out. This process is known as autolysis (or self-digestion).

B) It warms the clouds in the sky and causes precipitation.
C) It warms the water on the Earth's surface and causes it to evaporate.
D) It warms the water vapor in the clouds and turns it into water droplets.
Answer:
d
Explanation:
It warms the water vapor in the clouds and turns it into water droplets.
The process involved in the formation of rains is option B, it warms the clouds in the sky and causes precipitation.
What is water cycle ?Water cycle is a geological phenomenon through which the water content in the atmosphere and hydrosphere is balanced. The heat radiated from sun warm up the water bodies make the convection currents that evaporates water.
The water vapor rise to the atmosphere and maintain the air moisture. When this vapor cools down they condense and precipitates as rain, snow or sleek.
This process involves the transfer of heat energy and matter. Here, the matter is water itself with its three phases. Hence, option b describes the cause of rain.

Answer:not you cheating on the bsa but she doesn’t have a control group
Explanation:
A dependent variable is missing in her experiment. Therefore, the correct option is option C among all the given options.
What is experiment?The scientific method is a methodical approach to learning about the world around you, and the experiment is its cornerstone. Even while some experiments are conducted in labs, you may conduct an experiment anytime, anyplace.
You contrast an intervention design with only a control group in a controlled experiment. With the exception of the independent variable, these two groups should be identical. Christina wanted to know whether the eating behavior of goldfish is affected by music. She set up a fish tank. Every day, she played music for the fish an measured how much the fish ate.

In chickens, Black feathers (B) are dominant over white feathers (b). Complete the Punnett
Square for the following cross:
Mother: BB
Father: bb
What percentage of offspring will be Black?
What percentage of offspring will be White?
Answer:
(attached Punnett square below)
100% of the offspring will have black feathers
0% of the offspring will have white feathers
Explanation:
All the possible offspring have the genotype Bb, and since B (black) is dominant it will be the phenotype regardless of the presence of a b allele.
Therefore, all the offspring will be black (100%) and since none of the genotypes are bb there's no chance for white feathered chickens (0%)

Show are meiosis and mitosis different
Answer:
The purpose of mitosis is the creation of diploid somatic cells and the purpose of meiosis is the creation of haploid sex cells.
Explanation:
Mitosis takes place in somatic, or body cells, and meiosis takes place in gametes, or sex cells. The purpose of mitosis is growth and repair, while the purpose of meiosis is creating gametes with half the normal number of chromosomes and is for reproduction. Mitosis goes through Interphase, Prophase, Prometaphase, Metaphase, Anaphase, Telophase, and Cyokinesis once to produce two genetically identical diploid somatic daughter cells. Meiosis goes though that twice (Meiosis I and Meiosis II) to produce 4 genetically unique haploid gametes. It has stages (Prophase, Metaphase, Anaphase, and Telophase) such as Prophase I and Prophase II because meiosis occurs twice. Another difference is that mitosis happens throughout your life and meiosis occurs before females are born and throughout a males life.

how does nonradom matting affect the gene pool
Answer:
I think it's, the nonrandom mating is defined solely in terms of departures from HW proportions for neutral alleles, without reference to phenotypes. The impact is measured in terms of genetic parameters, such as genetic variance, expected gene flow, and Δ F, assuming the infinitesimal model and mass selection.
8. Which of these is the direct result of an error in the transcription of a DNA
nucleotide?
A. Amino acids do not bond to tRNA.
B. Transportation of mRNA does not occur.
C. The nuclear membrane is ruptured.
D. RNA sequence is incorrect.
CLEAR ALL
Answer:
D. RNA sequence is incorrect.
Explanation:
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
When a RNA sequence is incorrect, it leads to an error in the transcription of a DNA nucleotide.
This ultimately implies that, an error in the transcription of a DNA nucleotide is the direct result of an incorrect codon sequence (RNA nucleotides).
