Answer:
The correct answer is -
4/4
100%
Explanation:
In this question, it is given that allele B (blue) is dominant over allele b (purple) and both Randal and cell have the same genotype of recessive alleles that is bb and bb.
The offspring of these two will be the same as the due to gametes Randall and cella produce are same which is b and b.
b b
b bb bb
b bb bb
here all four out of four have the same purple skin with 100% chances.

A student claims that the lac operon is an example of a mechanism that an organism uses to conserve energy. Evaluate the validity of the student's claim. The claim is invalid because the lac operon requires a bacterial cell to produce extra regulatory proteins and regulatory segments of DNA. The claim is valid because the lac operon allows a bacterial cell to shut down a metabolic pathway if it is not immediately needed. The claim is valid because the lac operon allows a bacterial cell to maintain constant levels of enzymes even when they are not immediately needed. The claim is invalid because the lac operon requires a bacterial cell to constantly produce the lac repressor protein even when lactose is not present.
Answer:
The claim is valid because the lac operon allows a bacterial cell to shut down a metabolic pathway if it is not immediately needed.
Explanation:
The lac operon is a cluster of genes which contain the same promoter sequence and are transcribed as a single messenger RNA (mRNA). This operon is inducible because the presence of lactose in the cell influences its transcription. Lactose can bind to the repressor of this operon, leading to a conformation change in the repressor, thereby preventing the repressor from binding to the operator and thus allowing transcription of the structural genes. After lactose addition, the β- galactosidase enzyme can break this carbohydrate into glucose and galactose, thereby there is no lactose able to bind with the repressor and therefore this operon shuts down. During transcription, the promoter of the lac operon binds both RNA polymerase and catabolite activator protein (CAP) and cyclic AMP (cAMP) complex.
A triangle has side lengths 9, 10, and 12. Is it acute, obtuse, or right? Explain.
A. Right; 92 + 102 = 181 and 122 = 144, so a? + b2 = c2.
O
B. Obtuse; 92 + 102 = 181 and 122 = 144, so a+ b2 < c.
C. Acute; 92 + 102 = 181 and 122 = 144, so a2 + b2 >c2.
I dont really understand what yours asking but that triangle is acute because its sides are less then 90 degrees. Does that help??

write downany two organisms which shows binary fission
Answer:
Amoeba and Paramecium
Answer:
Amoeba,
Euglena
Explanation:
In biology, binary fission is a type of asexual reproduction where a parent cell divides, resulting in two identical cells, each having the potential to grow to the size of the original cell. ... Binary fission is common among prokaryotes, e.g. archaea, eubacteria, cyanobacteria, and certain protozoans (e.g. amoeba)

Describe the role that the protein INSULIN plays in a red blood cell
Answer:
helps maintain blood sugar
:)
Explanation:
The beta cells of the pancreas produce a peptide hormone called insulin. It is an anabolic hormone that regulates the activity of proteins, fats and carbohydrates in the body.
In blood cells insulin helps to:
Keep blood glucose levels
The role can be explained as:
Insulin is the anabolic protein that helps in breaking down carbohydrates, fats and proteins consumed in food. They signal the muscle and liver cells to absorb the glucose molecules present in the blood.They help the cells and tissues to regulate the glucose uptake for energy and also to store the excess glucose as a glycogen molecule.When there is an increased glucose concentration in blood cells then insulin cues liver cells to convert it into glycogen for future use.In the case of insufficient blood glucose it alerts liver cells to split the glycogen molecule into glucose for furnishing power and to counteract out the equilibrium in the body.Therefore, insulin regulates blood glucose levels.

HELPPP!!!! Which element is also an air
pollutant?
A. copper
B. lead
C. silver
D. zinc
Answer:
lead
Explanation:
Lead element is also an air pollutant. Thus option B is correct.
What are the air pollutants?
Any physical, chemical, or biological changes in air due to contamination by incorporation of harmful gases, dust, and smoke causes air pollution.
The imbalance in the gaseous concentration in air lead to global warming.
There are two major types of air pollutants such as Primary and Secondary Pollutants,
Primary pollutants cause air pollution directly and secondary pollutants are generated by intermingling of primary pollutants.
Lead, Fly Ash, Metallic Oxides, Nanoparticles, Carbon monoxide (CO), Carbon dioxide (CO2), Chlorofluorocarbons (CFCs), Ozone (O3), Nitrogen oxide (NOx), Sulphur dioxide (SO2) are some examples of air pollutants.
A hazardous heavy metal called Lead can cause serious damage to different physiological system of the human body like nervous system damage, Digestive system, affect kidney.
It can also cause cumulative food poisoning. Hence, Lead was banned to add fuels. Thus option B is correct.

Evidence exists that during the millions of years in which the Grand Canyon formed, the canyon divided a single population of tufted-eared squirrels into two populations. One of these squirrel populations, the Kaibab squirrel, now lives in isolation from the other tufted-ear squirrels on the North Rim of the canyon. The other population, the Abert's squirrel lives on the South Rim. Some biologists think that the two populations of squirrels have evolved into two separate species. Other biologists think that the Kaibab squirrel is a subspecies of the Abert's squirrel.
Answer:
A few of the squirrels manage to cross the canyon and breed with the squirrels on the other side.
Explanation:
The formation of the canyon divide the population of the tufted ear squirrels into two different population or species of the squirrels. One is the Kaibab squirrel which lives in the north Rim of the canyon while the other is the Albert's squirrel that lived in the South Rim.
The Kaibab squirrel has a black belly, white tails and tufted ears while the features of the Albert's squirrel is that it has white belly, white tail and tufted ears.
Now the factors that could make the evolution or the formation of the squirrel population in two different species less likely is the few of the squirrels might have crossed the Grand Canyon and moved to the other part and breeded with the squirrels there. So both the species have somewhat similar features.

What ratio of plants in the offspring would you predict from a Yy x Yy cross?
Answer:
The correct answer is -
The genotype of offspring - 1:2:1 (YY:Yy:yy)
The phenotype of offspring - 3:1 (dominant trait: recessive trait)
Explanation:
In this question, it is stated that there is a cross between Yy and Yy. By the genotype of the parents, we can say that Y is dominant for a particular trait and y is recessive and the parents are in the heterozygous condition in this cross. The gametes these parents will produce are - Y and y and Y and y
then the cross of Yy and Yy would be -
Y y
Y YY Yy
y Yy yy
Offspring from this cross are YY, Yy, Yy, and yy which means the genotypic ratio is - 1:2:1 and the phenotypic ratio is - 3:1 as three out of four are dominant.

New alleles can arise in both asexual and sexual reproduction.
Which of the following statements is TRUE based on the disadvantages of sexual and asexual reproduction.
A- Gametogenesis is the only source of genetic variation for sexual reproduction
B- This answer choice is wrong
C- Mutations are the only source of genetic variation for asexual reproduction
D- Meiosis is the only source of genetic variation for sexual reproduction
Answer:
C - Mutations are the only source of genetic variation for asexual reproduction
Mutations are the only source of genetic variation for asexual reproduction.
What is mutation?
A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.
A mutation is never so advantageous in real life that it makes someone a superhero or does anything strange like give them wings. There are numerous explanations for why mutations typically don't have significant effects.
Therefore, Mutations are the only source of genetic variation for asexual reproduction.
