Your best friend is concerned about a mole on her arm. Knowing that you are taking a biology class she comes to you and asks for your opinion. You take a sample of her mole and view it under a microscope. While counting a selection of 300 cells, you notice that 87 cells are actively undergoing mitosis. Should your friend be concerned?
Answer:
She should consult a dermatologist immediately.
Explanation:
When doing preemptive diagnosis of a mole, one should compute the Mitotic Rate (MR) - and the MR reported in the question is way above the highest category "greater than 4 per square millimeter" (to compare. there's around 2000 cells per sqmm of skin, so we're at over 500 per square millimeter).
Using the letter "T" and "t" with Tall height being dominant over short height. A heterozygous man for height marries a heterozygous woman for height. What is the correct F1 phenotypes for this cross?
75% would be tall, 25% would be short
genotypes: TT,Tt,tt

El gen I determina el tipo de sangre de una persona. Es un gen dialelico que muestra alelo dominante I y recesivo I. En personas de tipo A, los alelos son IA dominante, i recesivo.En personas de tipo B, los alelos son IB dominante, i recesivoIA e IB son codomiantes entre si, lo que signofica que hay un tercer fenotypo IAIB, expresando ambos tipos de sangre juntos.

Ecological succession usually includes changes in all of the following EXCEPT-
A. The number of different kinds of plants
B. The number of plants of any one species
C. The overall size of the dominant plants
D. The rate at which species produce offspring
Answer: its d i just took the test
Explanation:
Ecological succession usually includes change EXCEPT for the option" A" which is the number of different kinds of plants.
What is Ecological succession?Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.
Thus, according to ecological succession, the number of different kinds of plants.

dose DNA have cells
i need to know for a assingment
Answer and Explanation:
Cells are made of DNA (Deoxyribonucleic Acid).
They provide the genetic instructions for making and forming a cell.
The DNA is found inside the nucleus of the cell.
Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome
DNA do NOT have cells, but cells DO have DNA.

Carrying amino acids to the transcription site.
Moving mRNA strands into and out of the nucleus.
Splitting the DNA double strand into two single strands.
Forming an RNA strand using a DNA strand as a template.
Answer:
brown
Explanation:
have you pooped today?
The option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.
What is RNA polymerase?RNA polymerase may be defined as a multi-unit enzyme that synthesizes RNA molecules from a template of DNA through a process called transcription. This enzyme is responsible for copying a DNA sequence into an RNA sequence, during the process of transcription.
RNA polymerase binds to DNA, separates the strands, then uses one of the strands as a template from which to assemble nucleotides into a complementary RNA strand.
It uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.
Therefore, the option which describes the function of RNA polymerase is that it forms an RNA strand using a DNA strand as a template. Thus, the correct option for this question is D.

Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants
Answer:
Resistance plants increase in number whereas non-resistant plants decreases.
Explanation:
The environment of rain forest is suitable for the fungal growth because of the presence of humidity in the environment and we know that fungi needs moist places for its growth. These fungus attached on the leaves and takes nutrients from that plant that leads to the stunted growth and many cases death of the plant occurs. Some plants have no effect of this fungus due to the presence of resistance in them so if the fungus spreads in the whole forest so the plants which are prone to these fungal infections eliminated from that environment and resistant plants are increase in number.
Answer:
Part B
Many rain forest plants are prone to developing fungal infections on their leaves. Fungi can grow rapidly in moist environments, and a serious infection can kill plants. One rain forest plant species has a genetic variation that affects its leaf structure. The traits and the descriptions of the plant’s leaves are listed in the chart.
