O meristem tissue; gamete formation
O vascular tissue, production of sugar
O ground tissue, transportation of materials
dermal tissue, protection against damage
According to the given information, this tissue is ground tissue, transportation of materials
What tissue is found in the stem?The stem is composed of three tissue systems that include the epidermis, vascular, and ground tissues, all of which are made from simple cell types.
The xylem and phloem carry water and nutrients up and down the length of the stem and are arranged in distinct strands called vascular bundles.
Thus, option C ground tissue, transportation of materials is correct.

Create your own Python file in a code editor of choice and begin writing functions as defined below. Your function names, inputs, and outputs should be exactly as described. Please make sure you follow the coding guidelines from the main rubric! def dna_count(dna): This function takes in a string representing a DNA sequence and returns a list or tuple of four integers representing the number of times each nucleotide A, C, G, or T occur in the DNA string, in that order.
Answer:
In python:
def dna_count(dna):
A = dna.count('A'); C = dna.count('C')
G = dna.count('G'); T = dna.count('T')
dna_countlist = []
dna_countlist.append(A) dna_countlist.append(C)
dna_countlist.append(G) dna_countlist.append(T)
return dna_countlist
dna = input("DNA: ")
print(dna_count(dna))
Explanation:
This defines the function
def dna_count(dna):
This counts the occurrence of A and C
A = dna.count('A'); C = dna.count('C')
This counts the occurrence of G and T
G = dna.count('G'); T = dna.count('T')
This creates an empty list
dna_countlist = []
This appends the occurrence of A and C to the empty list
dna_countlist.append(A) dna_countlist.append(C)
This appends the occurrence of G and T to the list
dna_countlist.append(G) dna_countlist.append(T)
This returns the list
return dna_countlist
The main begins here
This prompts the user for the DNA string
dna = input("DNA: ")
This calls the dna_count function and also prints the returned list
print(dna_count(dna))

7. Compare the results of cell division in unicellular and multicellular organisms.
The results of cell division in unicellular and multicellular organisms in unicellular organisms such as bacteria, mitosis has a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.
What is difference between unicellular and multicellular organisms?The main difference between the unicellular reproduce organisms in other hand multicellular-repairs dead or damaged cells. They both help develop and grow in the multicellular this organism has been made up of 2 or more cell they can be made up to trillion if cells, it is much more complex than the unicellular. They reproduce asexually and the cells cannot live outside the organism, they perform specialized functions an example the nerves.
Cell division in unicellular organisms is important for reproduction. Unicellular cell division used for single-celled organism. Cell division in unicellular organisms is used for the reproduction of an organism.
The importance of cell division in multicellular organisms is the development and replacement of damaged and dead cells. Cell division is important for tissue growth and cell maintenance.
Therefore, The results of cell division in unicellular and multicellular organisms in unicellular organisms such as bacteria, mitosis has a type of asexual reproduction, making identical copies of a single cell.

b. Nutrients that leave the small intestine via blood are delivered first to the liver.
c. Lymph empties into the blood just before the blood reaches the heart.
d. Lymph is formed from fluid that Is forced out of capillaries by blood pressure.
Answer: b. Nutrients that leave the small intestine via blood are delivered first to the liver.
Explanation:
Lymph is a clear fluid that leeks out from the interstitial spaces of the cells and this comprises of electrolytes, blood proteins, and antibodies. It is pushed towards the heart from the lymphatic vessels. The nutrients from the small intestine are drained into the bloodstream and they are circulated to all parts of the body and not directly destined towards the liver.

Petrus brings his 87-year old grandmother to the emergency department where you work. His grandmother has a fever, is dehydrated and confused, and complains of pain when urinating. Petrus reports that she has not been eating or drinking, but she has no signs or symptoms of gastrointestinal distress. You request blood samples and also a urine sample. You decide to keep Petrus' grandmother in the hospital so that she can be given intravenous fluids. You also want to wait for the lab test results before you decide whether she required additional treatment or if she can return home.
1. When Petrus' grandmother's test results are sent to you, you discover that while her blood work is normal, her urine has Gram-negative bacilli in it. Based on this, you know that the cells are:______.
a) stained blue and are cylindrical in shape.
b) stained purple and are cylindrical in shape.
c) stained pink and are spherical in shape.
d) stained pink and are cylindrical in shape.
e) stained green and are oval in shape.
2. Petrus asks you what the Gram-negative result means and you explain that the bacteria causing his grandmother's UTI:____.
a) have a thin cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
c) have no cell wall but they have a thick outer membrane which makes the cells less sensitive to the antibiotic penicillin.
d) have a thin cell wall and an inner cell membrane which makes the cells less sensitive to penicillin.
e) have no cell wall which makes the cells more sensitive to the antibiotic penicillin.
Answer:
d) stained pink and are cylindrical in shape.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
Explanation:
Gram-negative bacteria are bacteria that do not retain the crystal violet stain. So they stain in pink and they have an outer cell membrane unlike gram positive bacteria.

What will occur if a species is divided into two groups and allowed to reproduce in different environments for many generations?
1. divergence, potentially giving rise to two different species
2. random mutations, all of which will decrease fitness
3. divergence, but these will never be two different species
4. natural selection, keeping both groups genetically static
If a species is divided into two groups and allowed to reproduce in different environments for many generations, it will produce divergence, potentially giving rise to two different species (Option 1).
What is divergence?Divergence refers to the emergence of genetic variation in a population, which occurs when individuals are separated.
Divergence may lead to speciation and the emergence of new species when variations are important enough to produce reproductive isolation.
Divergence and speciation due to geographical barriers are common evolutionary processes.

Answer: If a species is split into two groups and allowed to breed in extraordinary environments for many generations, it will produce divergence, doubtlessly giving upward push to two specific species (option 1).
Explanation: What is divergence?
Divergence refers back to the emergence of a genetic version in a populace, which takes place when individuals are separated.
Divergence might also lead to speciation and the emergence of recent species whilst variations are important enough to provide reproductive isolation.
