Explanation:
Bob has brown hair and Sally has blonde hair. If brown hair is dominant and blonde hair is recessive, is it possible for Bob and Sally to have a blonde-haired child? Use the GENOTYPE of each parent to EXPLAIN your answer.
Answer:
Yes, it is possible.
Explanation:
Bob could either be h.o.m.ozygous (BB) for brown hair or h.e.terozygous (Bb) for brown hair. If Bob is h.e.t.erozygous for brown hair, this means he has a blonde hair allele. For a child to be blonde, the child needs one blonde allele from each parent and this is possible if Bob has a blonde hair allele. However, it is not possible if Bob is h.o.m.ozygous for brown hair.
In the image, there is a punnet square showing the possible genotypes of the children if Bob is h.e.t.erozygous for brown hair.
Examine the flow chart above depicting the job of a gene known as p53. It plays an important role during the G2 checkpoint of cell cycle regulation. In 4-6 sentences, explain why p53 is often called "The Guardian of the Genome". Is p53 an oncogene (a gene that stimulates the growth of cancer cells) or a tumor suppressor gene (a gene that turns off the growth of cancer cells)? Explain your reasoning.
The p53 protein is known as the guardian of the genome because this protein prevents errors during DNA replication. It is a tumor suppressor gene.
Tumor suppressor genesTumor suppressor genes are genes that play fundamental cellular roles and prevent cell uncontrolled growth.
A tumor suppressor gene can repair errors that occurred during DNA replication, slow down the cycle of cell division, trigger programmed cell death, etc.
The p53 acts to control cell division and cell death, thereby avoiding the emergence of cancer cells.

What is Transpiration ???!
[tex]\huge \bf༆ Answer ༄[/tex]
Transpiration is the the phenomenon which generally occurs in plant, In which the plant looses water in the form of water vapour through stomata.
Two main functions of transpiration ~
It causes transpirational pull that helps in transportation of water from roots to upper portions of the plantIt helps to release excess waterPlant absorb a large quantity of water from the soil by roots . this water reaches to different part of the plant by ascent of sap . the total quantity of water absorbed by plant is more than their requirement. only a fraction of this water from a vapour throw the aerial parts like (stem , leaves , buds , and , flower) of plant which constitute about 95% of total absorbed water . this process is called transpiration .
Transpiration is vital process.This process mainly occur by stomata.Water evaporates in the form of vapour from aerial parts of plant.The loss of water per unit area is more It is regulated processTypes of Transpiration -:
1 Stomatal Transpiration ;
it take place through stomata present on leaves it is also called foliar Transpiration. it constitutes about 80-95% at total Transpiration.2 Cuticular Transpiration;
it take place by cuticle present on the epidermis of plant it is constituted about 5-10% of total transpiration it rate is high in tropical climate and low desert climate.3 Lenticular Transpiration
it take place through lenticles found in Woody stem and in some fruits it constitute 0.1-1% only of total transpiration.the process of food molecules reacting with oxygen is known as what process

1. Which is a source of genetic variation?
a. Mutations
b. artificial selection
C. exponential growth
d. genetic bottlenecking
Answer:
Mutation is a source of genetic variation
Answer:
Mutations
Explanation:
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.

how how does absorption of materials play a role in diffusion
The combined processes of absorption and diffusion are very necessary in the process of digestion.
The combined processes of absorption and diffusion are very necessary in the process of digestion especially in the intestines. The process by which nutrients enter the blood from the intestines is diffusion.
Diffusion occurs when the nutrients must have been absorbed into the blood from the intestines.

Question:
How to know that something is made up of a cell
Answer:
Cells are made up of a nucleus, and a cytoplasm, enclosed by a thin wall called a membrane, which separates it from its surroundings. Plant cells have a nucleus, cytoplasm, and a cell membrane too. The main difference between a plant and an animal cell is that plant cells have a vacuole, chloroplast, and a cell wall.
