Starch is a polysaccharide used as a component of cell walls in plants.
True
False
Answer:
false
Explanation:
is type of carbohydrates
False. Starch is a polysaccharide used as an energy storage molecule in plants, but it is not a component of cell walls.
What are structural component of cell wall?Cell walls are structural components found in the outermost layers of cells in plants, fungi, and some bacteria. They provide support and protection for the cell, and are composed of a variety of different biomolecules, including cellulose, pectin, and lignin.
Starch, on the other hand, is a complex carbohydrate that is synthesized and stored in the cells of plants, particularly in the seeds, roots, and tubers. It is made up of long chains of glucose molecules and is used by plants as an energy source, particularly during times when the plant does not have access to light for photosynthesis. Starch is not a component of cell walls.

Farmer toon soon wanted to start breeding his plants so that they are resistant to disease while producing more fruit per plant.Which plants should the farmers cross to get the desired (wanted) combination of traits
Answer:
cultivated plant variety with its wild type variety.
Explanation:
The farmer cross the cultivated plant variety to its wild type which has the characteristics of resistance against diseases. Due to crossing, the offspring produce having resistance against that disease as well as producing high yield. This type of crossing is known as artificial selection in which humans cross two organisms to get the desired characteristics in their offspring so to get a plant with resistance against disease we cross cultivated plant variety to its wild type.
write a short story on the journey of a sperm cell seeking to enter in a egg cell to share life together as a zygote and beyond
(See the attached picture)
Direction: Write a short story on the journey of a sperm cell seeking to enter in a egg cell to share life together as a zygote and beyond.
Answer:The goal of the sperms’ journey to the egg is to fertilize it. To do so, the sperm cell must pass through a long and challenging path. This is one of the reasons why the total number of motile sperm cells is very important, and a key parameter for a man’s potential to reach pregnancy with his partner.
The sperms’ journey to the egg begins with millions of sperm cells that are released into the female reproductive tract during intercourse. The sperm cells gain their full ability to swim when they are ejaculated into the reproductive tract.
Upon ejaculation, the sperm cells are enclosed in a fluid called seminal plasma or semen, which is a mix of fluids from the testes, seminal vesicles, prostate, and the bulbourethral glands. The fluid contains elements which protect the sperm cells during their journey towards the egg. The semen thickens and helps the sperm cells stay inside the woman – as close as possible to the cervix, which is the “gate” to the egg.
Liquid extends from the cervix, allowing the sperm cells from the semen to swim into the cervix. Only the strongest sperm cells will make it this far. Once through the cervix, the sperm cells swim across the uterus and into the fallopian tubes.
I hope it helps!!The sperm cell fertilizes the egg and forms a zygote, which is further divided into multiple cells and becomes a child. The division is the process of mitosis that takes place from the zygote to the child's development.
How is the zygote formed and developed?The sperm and the ovum are produced by the process of meiosis from the male and female, respectively, and when both fertilize, the zygote is formed. The fertilized zygote is a single cell, but later that cell is further divided mitotically and forms a morula, then a blastula, and then the gastrula.
The cells of the gastrula undergo cell differentiation, different organs are developed, and the baby is finally formed. The child then continues to grow in size, and different organs grow and form the mature organ system. After a certain age, the reproductive organs start to mature and are capable of forming the gametes.
Hence, all of these events occurred from the zygote to the child's maturity.

Write mechanism of absorption
Answer: The mechanism for absorption is that a photon transfers all its energy to an electron in the absorbing material. The photon is "lost" from the light beam as it is absorbed in a single event. The electron is excited by the gain in energy to a higher energy state in the electron configuration around the atom. (hope it helps)

Explain how different types of cells help organisms live and grow?
Different types of cells have different jobs that are necessary to keep organisms alive.
Different types of cells are only found in specific types of organisms.
Cells are necessary in order for all organisms to grow big and hunt for their food source.
Cells provide support for all organisms to be able to move.
Answer:
Different types of cells have different jobs that are necessary to keep organisms alive. And cells also give the living animal more support. They also hold the genetic information of that organism in their nucules. This is with most cells but bacteria cells do not contain nucules.

Answer:

- DNA 5' UTR: ATTTTAGCC
- RNA 3' UTR: UAAAAAUAAAAU
Explanation:
Transcription is the process in which a DNA sequence (e.g., a gene) is used as template (transcribed) in order to synthesize an RNA molecule, usually a messenger RNA molecule, which is then used as template to produce a polypeptide sequence (protein) in the ribosomes. In RNA, Thymine (T) bases are always replaced by Uracil (U) bases. An mRNA strand is formed in the 5′ to 3′ direction. Each triplet of nucleotides is referred to as a codon and the resulting mRNA strand is translated starting from codon AUG (Methionine), while there are three different stop codons or 'or termination codons' in the genetic code that terminate translation: UAG, UAA, and UGA.
i need help with this question
Mr. and Mrs. Green have a daughter, Georgia, who was born at Riverside Community Hospital. Mr. and Mrs. Blue have a daughter, Belle, who was born on the same date at the same hospital. Mrs. Green, having recently seen Belle, is convinced that Belle and Georgia had been assigned to the wrong parents at the hospital. Mrs. Green thinks that Belle is her biological daughter. ABO blood analysis was performed on all individuals involved:Mr. Green: Type AMrs. Green: Type A Georgia: Type AMr. Blue: Type ABMrs. Blue: Type ABelle: Type O
Is Mrs. Green correct? Is Belle her biological daughter? Explain.
Answer:
Yes, Mrs Green is correct that Belle is her biological daughter
Explanation:
According to this question, Mr. and Mrs. Green is said to have a daughter, Georgia while Mr. and Mrs. Blue is said to have a daughter, Belle. Both daughters were born the same day. Hence, a controversy occured as Mrs. Green thinks that Belle is her biological daughter.
Based on the blood analysis, the following were obtained:
Mr. Green: Type A
Mrs. Green: Type A
Georgia: Type A
Mr. Blue: Type AB
Mrs. Blue: Type A
Belle: Type O
The genotype of the following blood types is as follows:
Type A - iAiA or iAi
Type B - iBiB or iBi
Type O - ii
Type AB - iAiB
From the analysis of blood types of Mr and Mrs Green, which are both type A, they can possibly produce a child with type A.
However, from the analysis of Mr. and Mrs. Blue, it is impossible to have a child with blood type O. However it is possible for Mr and Mrs. Green if they are both heterozygous (iAi × iAi). The punnet square is attached. Hence, Mrs Green is correct about her claim since Mr. and Mrs. Blue cannot have a child with blood type A.
