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.

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%)

B. its ability to accept and release high-energy electrons and a hydrogen ion

Explanation:

Answer: The probability of an event is a number describing the chance that the event will happen. An event that is certain to happen has a probability of 1. An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.

The number Which describes how likely it is that an event will occur is the probability of the event.

The number describing a chance that an event will occur is called probability. It can be expressed in the form of numbers, from 0 and 1, or also by percentage from 0% to 100%. Higher probability of an event means that there are greater chances that event will occur.

Probability is branch of mathematics which is also applied in other fields such as, science, finance, statistics, gambling, computer science, machine learning, artificial intelligence and game theory.

Representation of probability in its formal terms, is called as probability theory. The probability theory is mostly used in risk assessment and modelling that is, it is used by insurance companies and markets.

Therefore, chances of number of event occur is called probability.

I think it is maintaining water balance since transpiration in plants is basically when the plants roots absorb water and then release the water in the form of vapour (Don't know much about plants but I think maintaining water balance is most probably the answer)

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.

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.

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. A dependent variable is missing in her experiment.

Therefore, the correct option is option C.

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.

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).

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).

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.

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.
