Complete question:
A researcher had 15 pure-bred wild mice which were brown and all were females. They were all mated with a male called Bob. All the offspring were brown. These were then crossed among themselves with the following results: 293 brown and 115 white.
(i). Determine the color of Bob.
(ii). Determine which color is dominant.
(iii). Work out the ratio of brown to white in the ‘grandchildren.’
(iv). If the researcher crosses two of the white 'grandchildren', determine the color of their offspring.
Use the Punnett square to work out your answers
Answer:
(i). Determine the color of Bob. BOB IS WHITE
(ii). Determine which color is dominant. BROWN IS DOMINANT
(iii). Work out the ratio of brown to white in the ‘grandchildren.’
PHENOTYPIC RATIO BROWN TO WHITE 3:1
(iv). If the researcher crosses two of the white 'grandchildren', determine the color of their offspring. THE WHOLE PROGENY WILL BE WHITE

plz help!!A biologist claims that during lake succession, fish such as trout are slowly replaced by fish such as bluegills. How must these fish be different for this claim to be TRUE?
A. Bluegills must be larger than trout.
B. Bluegills must require less oxygen than trout.
C. Bluegills must require less nitrogen than trout.
D. Bluegills must have a greater population size.
Answer:
D. Bluegills must have a greater population size.
Explanation:
Hope this helps!
Trout fish are slowly replaced by Bluegills fish because Bluegills must have a greater population size.
What is Lake Succession?
Lake succession is a term used to describe the process of continuous aging in a lake in terms of its physical and biological properties.
As the population size of Trout fish is lesser, and the process of succession happens, it is replaced by the species that have greater population size.
Therefore, Trout fish are slowly replaced by Bluegills fish because Bluegills must have a greater population size.

How is traffic compared to size?
Answer:
A traffic counter is a device, often electronic in nature, used to count, classify, and/or measure the speed of vehicular traffic passing along a given roadway. These devices generally use some sort of transmitted energy such as radar waves or infrared beams to detect vehicles passing over the roadway.

2. What is the purpose of translation? Where does it happen in the cell?
Answer:
The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.

1. True
b. False
Leopards and lancelets have no common ancestor.
1. True
b. False
The taxon that shares the most recent common ancestor with frogs is the bass.
1. True
b. False
In this tree, frogs are the sister taxon of turtles and leopards.
1. True
b. False
Turtles and leopards all have four limbs and an amnion.
1. True
b. False
The common ancestor of lamprey and lancelets have a vertebral column.
1. True
b. False
Answer:
Explanation:
1) False.
This is because bass is a fish, turtle is an amphibian and leopard is a mammal. But bass possess some characteristics traits related to turtle as compared to a mammal(leopaard)
2) False
This is because their ancestor is a Chordate , therefore they have a coin ancestor.
3) True
The taxa of turtles( amphibians) share a more common ancestor with frogs compared to bass because both are amphibians.
4) False
This is because the bass is a fish that possess some characteristics traits related to an amphibian (turtle) as compared to a mammal(leopard).
5) True
They all have the fore limb and hind limb.
6 True.
how does an organism use the information in dna
Explanation:
DNA's instructions are used to make proteins in a two step process.
1st- Enzynes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid (mRNA).
2nd- Information contained in the mRNA molecule is translated into amino acids, which are the building blocks of proteins.
The RNA copy goes through a protein “factory” called a (n)
What is it called?
Answer:
transcript
Explanation:
The RNA copy goes through a protein “factory” which is called Ribosomes.
What is the process of copying RNA into protein?The Central Dogma of Molecular Biology states that DNA makes RNA and makes proteins (Figure 1). The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.
What does transfer RNA deliver to the protein factory?A workhorse in the factory
Among RNA's most important roles is the transcription and delivery of genetic instructions from the nucleus to the cytoplasm where proteins are made.
What is called the protein factory?What looks like a jumble of rubber bands and twisty ties is the ribosome, the cellular protein factory. The ribosome is made up of proteins and strands of RNA, a chemical relative of DNA. It has two interlocked parts that behave as a single molecular machine to assemble all of the cell's protein molecules.

In your own words, explain what happens in the process of Transcription versus what happens in Translation. What is the end result?
Answer:
Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.

Organ systems work together to meet the needs of the human body. How is the skeletal system related to the nervous system?
Answer:
The Skeleton forms a framework for the body and the joints of the bones hold the muscles together.Hence the muscles can move when there's an impulse from the brain (through nervous system.)
