7. Some plants make cones. Other plants make flowers. What is the purpose of flowers and cones?
A. They move water and food throughout the plant.
B. They hold the plant and soil so that it does not blow over in heavy winds.
C. They make seeds so that the plant can reproduce.
D. They take in water and nutrients from the soil.
Answers
Answer:
I believe the answer is C.
Explanation:
Coniferous plants (= cone bearing) carry seeds in their cones. This leads me to believe the answer is C because cones do not move water, nutrients, or hold soil.

When a filament of algae is illuminated with light that is passed through a prism, different segments of algae are exposed to different wavelengths of light. When aerobic bacteria are present, they congregate in highest concentrations in the areas illuminated by the red and blue light. These data suggest a relationship between which of the following variables?
a) Wavelength of light and rate of aerobic respiration
b) Wavelength of light and amt of heat released
c) Wavelength of light and the rate of photosynthesis
d) Carbon dioxide concentration and the rate of photosynthesis
Answers
Answer:
The correct answer is C) wavelength of light and rate of photosynthesis.
Explanation:
The given question is a famous experiment conducted by T W Engelmann which is called the action spectrum experiment. In this experiment when light passes through a prism it splits into its constituent colors splits into violet, indigo, blue, green, yellow, orange and red.
Aerobic bacteria require oxygen for their survival. The green algae produce oxygen during photosynthesis. Engelmann released aerobic bacteria to it. it is found that the bacteria accumulated at the blue and red light because photosynthesis and oxygen release were higher there. So, it establishes the relationship between the wavelength of light and photosynthesis.
Place the following events in the order they occur by listing their assigned letters in that order. A. Cas9 REC domains binds to the guideRNA B. Cas9 complex binds to dsDNA C. Cas9 complex scans dsDNA for PAM sequence D. Cas9 unwinds dsDNA E. The programmable part of the guideRNA binds to its complementary sequence F. Cas9 cuts both strands to generate a double strand break
Answers
Answer: a, b, d, c, e, f
Explanation: The steps of Cas9 DNA recognition and cleavage goes in the following order lettered A, B, D, C, E and F. Cas9 recognizes and binds the sgRNA after which it binds to the double stranded DNA. It then unwinds and scans the dsDNA for its protospacer adjacent motif sequence (PAM) and on recognition the sgRNA binds to its complementary sequence followed by cleavage of the DNA at two points. That is how the double stranded break is created.

Description: Cellular respiration is the process that allows your body to harvest a huge amount of energy from a single glucose. In fact, it's so efficient that you get 30 ATP for every 1 glucose molecule you eat. This exercise is going to break down exactly where each ATP comes from.
Instructions: For this presentation, your goal is to walk the audience through every step that is involved in generating an ATP, NADH or FADH2, include the names, structures and enzyme for each step. From there, look up the conversion rates from NADH and FADH2 to ATP and calculate exactly how 30 ATP are formed. Also include any step which uses an ATP (this will count against the total ATP formed).
What to submit: Please record yourself explaining the structures and enzymes as well as ATP calculation.
Description: For the video response portion of this assignment, your job will be to calculate the amount of ATP produced anaerobically using the logic of the person’s presentation you watched. Discuss whether or not you agree with this.

Extra-large breakers are crashing into the surf. How will this affect the undertow? Make a prediction
Answers
Answer:
This will make the undertow return to the sea with greater intensity and violence.
Explanation:
Undertow is the movement of the wave in contrast to the sea, that is, it is the movement of the waves on themselves, which makes the sea very agitated, especially when these waves return to the sea with a lot of violence and force. Although this violence and force can be caused by the wind, extra-large breakers can also cause this effect, because the impact of the waves on the breakers, pushes the waves into the sea with more force, making them more violent and intense.

Explanation:
You should be familiar with the drugstore antibiotic ointment Neosporin (Triple antibiotic ointment), which is often thought of as innocuous. Based on your knowledge of antibiotics from Chapter 12 describe the mode of actions of the three antibiotics found in Neosporin (neomycin, polymyxin, and bacitracin), research their side effects, and postulate on why these three antibiotics were chosen.
Answers
Answer: Antibiotics are chemicals which, in low concentrations, can selectively kill or inhibit the growth of most pathogenic bacteria and are not harmful to humans.
Explanation:
Neosporin is a type of antibiotics which is used for the treatment or prevention of mild superficial infections. It consists of three active component, hence the name Triple antibiotic ointment. These active components, their mode of action and side effects include:
--> NEOMYCIN : This is one of the active components of Neosporin which inhibits the protein synthesis of an invading pathogenic bacteria through irreversible binding to the 30 S ribosomal subunit of susceptible bacteria. Their MODE OF ACTION is bactericidal meaning that the effect it has on the protein synthesis inhibits it's growth leading to the death of the bacteria.
SIDE EFFECTS: it can cause irritation, burning, itching, rash redness when applied topically.
--> POLYMYXIN: This is one of the active components of neosporin which attacks the invading pathogenic gram negative bacteria. In its mode of action, is the ability to combine with and disorganise structures of the bacterial cell which are responsible for the maintenance of the osmotic equilibrium of the cell thereby exposing the underlying peptidoglycan layer to lysozyme.
SIDE EFFECTS: Burning, redness, or irritation of the skin may occur.
--> BACITRACIN: This is also one of the active components of Neosporin. In its mode of action, it inhibits bacterial cell wall synthesis. This is achieved by preventing the final dephosphorylation step in the phospholipid carrier cycle, which interferes with the mucopeptide transfer to the growing cell wall.
SIDE EFFECTS: it may cause rash, itching/swelling (especially of the face/tongue/throat).
These three active components of Neosporin are combined to broaden the antibacterial spectrum. This means that at least one of the active components will effectively kill an invading pathogenic bacteria through its unique mode of action.
Typically, acetylation of histone tails leads to ________. Typically, acetylation of histone tails leads to ________. relaxed packaging of the chromatin and increased transcription activation of topoisomerase removal of the protein components of the chromatin from the DNA tighter packaging of the chromatin and reduced transcription increased amounts of euchromatin relative to heterochromatin
Answers
Answer:
relaxed packaging of the chromatin and increased transcription.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.
Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
