Question 65
It is believed that the ingestion of one virus CFU can cause infection in humans.
a. True b. False
The statement "It is believed that the ingestion of one virus CFU can cause infection in humans" is generally true.
CFU stands for "colony-forming unit," which is a measure of the number of viable microorganisms present in a sample. In the case of viruses, a single virus particle can potentially infect a host cell and cause an infection. However, the infectious dose (i.e. the number of virus particles needed to cause infection) can vary depending on the specific virus and the individual's immune system
Counting with colony-forming units requires culturing the microbes and counts only viable cells, in contrast with microscopic examination which counts all cells, living or dead. The visual appearance of a colony in a cell culture requires significant growth, and when counting colonies, it is uncertain if the colony arose from one cell or a group of cells. Expressing results as colony-forming units reflects this uncertainty.

Using the illustration above, why are the chromosomes in two of the sex cells different from the chromosomes in the parent cell?
A
the chromosomes from another parent cell were introduced
B
crossing over occurred in the chromosome
C
an insertion mutation occurred during replication
D
some of the genes were damaged during replication
Answer: A the chromosomes from another parent cell were introduced
Explanation: A child is created when the male sex cell joins the female cell. If the male and female sex cells had the standard number of chromosomes, as is found in body cells then the zygote (baby) would have double that number of chromosomes. The number of chromosomes would keep doubling every generation. To avoid this doubling the parent's body cells split by miosis which halves the number of chromosomes and so when the sex cells join the total number of chromosomes is the same as that found in the parent's body cells.

Answer:
Left; Right
Explanation:
Brain-intact people are more likely to have increased activity in the Left hemisphere when identifying the small letters (A) and increased activity in the Right when identifying the overall pattern (X).
The left hemisphere controls the right part of the body and the right hemisphere controls the left part of the body. The left hemisphere performs functions such as language and logical analysis in which identification of small letters is included.

Can someone reword this for me? It's for my biology project and I don't think it's good.
I used a plastic Betta Fish Bowl and succulent plants to make this terrarium. For the bottom base, I used gravel. I added one inch of gravel on the bottom and two inches of potting soil on top. Next, I added moss on top of the potting soil. I then dug a small hole and planted all three plants. Next, I added half a cup of water to the plants and covered them with saran wrap.
Photosynthesis begins with light reactions. These reactions occur when chlorophyll, a pigment in the chloroplast's thylakoid membrane, absorbs energy from the sun. During the light-dependent stage "light" processes, chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these then leave the chlorophyll and pass through a series of molecules, producing NADPH, an enzyme, and high-energy ATP molecules.
Carbon dioxide from the light reactions is combined with ATP and NADPH from the dark reactions to produce glucose in the dark reactions. This reaction occurs in the chloroplast's stroma. The dark reaction takes place outside the thylakoids. ATP and NADPH provide the energy needed to repair carbon dioxide (CO2). Sugar molecules and other organic chemicals required for cell function and metabolism, as a result, are produced.
Photosynthesis is affected by temperature, light intensity, carbon dioxide levels, water, oxygen, and chlorophyll. The rate of photosynthesis increases with temperature. When the temperature reaches a certain level (usually 35 C), the speed slows down. However, the rate of photosynthesis increases as the intensity of the light increases.
This terrarium was created using a plastic Betta Fish Bowl and succulent plants. I used gravel for the bottom base. On the bottom, I put one inch of gravel and two inches of potting soil. Then, on top of the potting soil, I sprinkled moss. After that, I dug a tiny hole in which I put all three plants. After that, I gave the plants half a cup of water and wrapped them in saran wrap.
Light reactions are the starting point for photosynthesis. When chlorophyll, a pigment in the chloroplast's thylakoid membrane, receives energy from the sun, several events occur. During the "light" processes of the light-dependent stage, chlorophyll absorbs light energy, which excites some electrons in pigment molecules to higher energy levels; these electrons then leave the chlorophyll and pass through a series of molecules, producing NADPH, an enzyme, and high-energy ATP molecules.
In the dark processes, carbon dioxide from the light reactions is mixed with ATP and NADPH from the dark reactions to make glucose. This process takes place in the stroma of the chloroplast. Outside of the thylakoids, the dark reaction occurs. The energy required to fix carbon dioxide is provided by ATP and NADPH (CO2). As a result, sugar molecules and other organic compounds necessary for cell activity and metabolism are created.
Temperature, light intensity, carbon dioxide levels, water, oxygen, and chlorophyll all impact photosynthesis. With increasing temperature, the rate of photosynthesis rises. The pace slows down when the temperature reaches a specified threshold (typically 35 C). However, as the intensity of the light increases, so does the rate of photosynthesis.

identify the type of growth response that each plant demonstrates
Plant growth responses can be categorized into two types: tropisms and nastic movements.
Tropisms are directional growth responses of plants towards or away from a stimulus. On the other hand, nastic movements are non-directional growth responses, which occur independently of the direction of the stimulus.
For instance, plants show positive phototropism, a type of tropism in which they grow towards light. This is due to the presence of auxin, a hormone that causes the plant cells to elongate, making the stem bend towards the light. Similarly, plants show negative gravitropism, in which they grow away from gravity, allowing them to grow upwards.
Another type of growth response is thigmotropism, which is the directional growth of a plant in response to touch or contact. For instance, some plants curl their tendrils around objects to climb or support themselves, such as peas, grapevines, and ivy.
Plants also exhibit nastic movements such as nyctinasty, a rhythmic movement that occurs in response to light and darkness. Some plants such as the sensitive plant close their leaves when touched, which is known as thigmonasty.
In conclusion, the growth responses of plants are diverse and varied. These responses enable plants to adapt and respond to their environment, allowing them to survive and thrive.

which cells carry antigen-specific receptors and are stimulated when antigens bind to those receptors?
The surface immunoglobulin that serves as the B cell antigen receptor (BCR) has two functions in B cell activation. First, like the antigen receptor on T cells, it transmits signals directly into the cell when it binds to the antigen receptor. antigen.
B cells have B cell receptors (BCRs) on their surface, which they use to bind to a specific protein. Once B cells bind to this protein, called an antigen, they release antibodies that attach to the antigen and prevent it from harming the body. The antigen receptor on most T cells, the α:β T-cell receptor, is composed of two protein chains, the α T-cell receptor and the β T-cell receptor, and resembles in many respects a single immunoglobulin Fab fragment. T cell receptors are always membrane bound. The membrane-bound immunoglobulin on the surface of B cells serves as the cell's receptor for the antigen and is known as the B cell receptor (BCR). Terminally differentiated B cells, plasma cells, secrete immunoglobulin with the same antigen specificity as antibody.

What is carrier proteins ?In contrast to channel proteins, another type of membrane transport protein, which is less selective in transporting molecules, a carrier protein is a type of protein that moves a particular substance through intracellular compartments, into the extracellular fluid, or across cells.It is similar to an enzyme-substrate reaction in how a carrier protein moves a solute molecule across the lipid bilayer, and in many respects, carriers work like enzymes. However, unlike regular enzyme-substrate reactions, the carrier protein does not covalently modify the transported solute before delivering it to the other side of the membrane.There are one or more distinct binding sites for a solute in each type of carrier protein. By undergoing reversible conformational changes that alternately expose the solute-binding site on each side of the membrane, it moves the solute across the lipid bilayer.To learn more about carrier proteins refer :

a. What strategies are used by each technology to sequence millions of different molecules at the same time?
b. Explain why fluorescent chain terminator nucleotides are used in Illumina, but not in PacBio.
c. Which technology does not use fluorescent nucleotides? How are different nucleotides distinguished from one another?
High-throughput sequencing technologies are a set of methods that enable the rapid sequencing of large amounts of DNA. These technologies include Illumina, PacBio, and Oxford Nanopore. Each technology uses a different strategy to sequence millions of different molecules at the same time.
Illumina uses bridge amplification to create clusters of identical DNA molecules, which are then sequenced by synthesis using fluorescent chain terminator nucleotides.
PacBio uses single-molecule real-time (SMRT) sequencing, in which a single DNA molecule is sequenced in real-time as it is synthesized by a DNA polymerase.
Oxford Nanopore uses nanopore sequencing, in which a single DNA molecule is passed through a nanopore and the electrical current changes as different nucleotides pass through the pore.
Fluorescent chain terminator nucleotides are used in Illumina because they allow for the detection of each nucleotide as it is incorporated into the growing DNA strand. This is not necessary in PacBio, as the DNA polymerase used in SMRT sequencing is modified to include a fluorescent molecule that allows for the detection of each nucleotide as it is incorporated.
Oxford Nanopore does not use fluorescent nucleotides. Instead, different nucleotides are distinguished from one another based on the changes in electrical current as they pass through the nanopore. Each nucleotide has a unique electrical signature, which allows for their identification.
