Answer:
The plant would not be able to grow to normal height.
Explanation:
If a plant does not develop a root cap, the plant does not allow the root to grow downwards.
Hope this helps :)
If a plant is unable to produce root caps, the plant will be unable to absorb water from the soil; this is the final option, as root caps are a specialized protective layer at the tip of plant roots that help protect the plants.
What is the significance of the root cap in the plants?The root cap contains cells that are capable of secreting slime, which helps the root to move easily through the soil, helps to maintain the proper orientation of the root tip so it can efficiently absorb water and nutrients from the soil, and acts as a barrier that protects the delicate root tip cells as the root grows through the soil.
Hence, if a plant is unable to produce root caps, the plant will be unable to absorb water from the soil; this is the final option, as root caps are a specialized protective layer at the tip of plant roots that help protect the plants.

Answer:
Simple dominance is when the dominant gene in a heterozygous organism expresses the dominant phenotype. Incomplete dominance is when a heterozygous organism exhibits a blending of both genes, recessive and dominant. Red and white flowers will "blend" and make pink flowers.
Incomplete dominance, only one allele in the genotype is seen in the phenotype. In simple dominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
Down syndrome in humans is due to ________ of the 21 st chromosome.
Answer:
Down syndrome in humans is due to ADDITIONAL, PARTIAL OR FULL COPY of the 21 st chromosome.
Explanation:
Down syndrome is a genetic disorder in which an individual has a total of 47 chromosomes instead of 46 that is, 23 pairs of chromosomes which is found in normal individuals. This occurs as a result of the presence of additional, partial or full copy of chromosome 21. There are generic variations that occurs in chromosome 21 leading to down syndrome, these include:
-->Trisomy 21 : the individual has three copies of chromosome 21 instead of two copies due to abnormal cell division that occurred during development of sperm or egg.
--> Mosaic Down syndrome: the individual has some cells with an extra copy of chromosome 21 and it's caused by abnormal cell division after fertilization.
--> Translocation down syndrome: This type of down syndrome occurs when chromosome 21 gets attached to another chromosome which occurs during or after conception.
Generally the symptoms due to the presence of this extra genetic material includes:
--> short heights
--> poor muscle development
--> short neck
--> short fingers with small hands and feet
--> increased risk to development of dementia
--> greater tendency to develop obesity

Two students compare and contrast the composition of a plant and animals cells. Several observations are made during the investigation. Which observation is incorrect?
Plant and animal cell contain cell membranes.
Plant cell are contained within cell walls, while animal cells are not.
Plant and animal cells contain a nucleus.
Plant cell do not have cytoplasm.
Answer:
I believe the correct answer would be D- Plant cell do not have cytoplasm
Explanation:
Plant and animal cells both have a cytoplasm so D is the incorrect statement.
Two students compare and contrast the composition of a plant and animals cells. Plant cell do not have cytoplasm this observation is incorrect. Therefore, option D is correct.
What is cytoplasm ?The liquid present inside a cell but not in the nucleus of the cell. In a cell, the cytoplasm is where the majority of chemical processes occur.
The gel-like substance that fills a cell is called cytoplasm. It serves as a catalyst for chemical reactions. It offers a foundation for other organelles to function within the cell. A cell's cytoplasm is where all the processes for cell division, growth, and replication take place.
Rudolf von Kölliker coined the phrase in 1863, first using it as a synonym for protoplasm, but over time it has come to refer to the cell's interior and extracellular organelles.
The first phase of cellular respiration, known as glycolysis, as well as mitosis and meiosis are just a few of the numerous cellular processes that take place in the cytoplasm.
Thus, option D is correct.

An acid-fast staining method was performed on a bacterial smear using the dyes carbol fuchsin and methylene blue. The resulting stained slide contained only cells that appeared blue when visualized using a microscope. Which of the following could explain why only blue cells were present?
a. No acid-fast bacteria are present on the slide
b. Methylene blue was not used
c. Carbolfuchsin was not used
d. Acid-alcohol was not used
Answer: Only blue cells where present because No acid-fast bacteria are present on the slide. The correct option is A.
Explanation:
Acid fast staining method also called Ziehl-Neelsen (Zn) technique is used in the laboratory to stain samples suspected to contain Mycobacterium species. The Mycobacterium species which includes the M. tuberculosis, M. ulcerans, and M. leprae, do not stain well by the Gram technique, which is a common routine stain in the laboratory. This is because of waxy coating on its cell surface primarily due to the presence of mycolic acid.
The acid fast stain consists of:
--> A primary dye which is the carbol
fuchsin
--> A decolorizer which is the acid alcohol
--> A counter stain which is the methylene blue.
In it mechanism of action on the bacterial smear, when the primary dye is applied,the whole cell will appear red. But after decolorizing with acid alcohol, only acid fast bacteria will retain the red colour of carbol
fuchsin while the red dye from the background cells are removed. Then the counterstain (methylene blue) is applied which is picked up by non-acid-fast bacteria making the cells appear blue under the microscope.
Therefore when the bacteria smear is viewed under the microscope and only blue cells are seen, it means No acid-fast bacteria are present on the slide.

In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms.
a. True
b. False
Answer:
Explanation:
True.
In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms is a true statement.
What are Bacterial communities?Bacterial communities differ in their species makeup, the niches they occupy, and the effects they have on various ecosystems.
Communities defy a single, fundamental definition due to their complexity. Instead, they offer fascinating illustrations of dynamic processes that vary with ecological size. In the beginning of microbiology, there were difficulties in describing and classifying communities.
Robert Koch revolutionized the study of microbiology in the late 1800s by inventing his techniques for proving the link between an infection and an organism (Koch, 1876). Koch's hypotheses continue to be the "gold standard" for linking germs to illness or any other interesting event.

Two pea plants heterozygous for the characters of pod color and pod shape are crossed. Assume that G allele stands for green pod color, g allele−for yellow pod color, I allele−for inflated pod shape, and i allele−for constricted pod shape. Complete the Punnett square for this cross.
Answer:
Please find the punnet square in the attachment section
Explanation:
This question involves two different genes; one coding for pod color and the other for pod shape. The allele for green pod color (G) is dominant over the allele for yellow pod color (g) while the allele for inflated pod shape (I) is dominant over the allele for constricted pod shape (i).
According to this question, two pea plants heterozygous for both of the characters or traits are crossed i.e. GgIi × GgIi. Each heterozygous parent will produce the following possible gametes:
GgIi - GI, Gi, gI and gi.
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
- Green, inflated pods (G_I_) = 9
- Green, constricted pods (G_ii) = 3
- Yellow, inflated pods (ggI_) = 3
- Yellow, constricted pods (ggii) = 1
