Demography is the statistical study of human populations. Demography examines the size, structure, and movements of populations over space and time. It uses methods from history, economics, anthropology, sociology, and other fields.
A scientist performs a series of mutation screens to look for mutations that reduce ATP production. One of the mutants, compared to a wild-type cell, has reduced levels of ATP and NADH and increased levels of FAD and pyruvate. Which hypothesis best fits these observations?
The hypothesis that best fits the observation that one of the mutants has reduced levels of ATP and NADH and increased levels of FAD and pyruvate is that the mutation is disrupting the citric acid cycle (Option 3).
What is the citric acid cycle?The citric acid cycle, also known as the Krebs cycle, is the second step of cellular respiration which is required to generate ATP through the oxidation of pyruvate.
The reduced form of Nicotinamide adenine dinucleotide (NADH) produced during the citric acid cycle is then used in oxidative phosphorylation (the third step of cellular respiration) in order to generate more ATP.
Therefore, with this data, we can see that the citric acid cycle generates the reduced form of Nicotinamide adenine dinucleotide (NADH) and thus increases the production of ATP, thereby a mutation in an enzyme that works in this pathway may also hamper the proportion of ATP.
Complete question:

active transport moves mineral ions into root hair cells through cell membrane proteins. Explain how protein molecules move ions across a membrane during this process. (3marks)
Explanation:
Small and nonpolar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.
Nonpolar and small polar molecules can pass through the cell membrane, so they diffuse across it in response to concentration gradients.
Which of the following is NOT part of the non-specific immune response?
A. Inflammation
B. Phagocytosis
C. Antibodies
D. Interferons
D. Interferons are not a part of the non-specific immune response.
What is the function of interferons?Interferons were first described as an antiviral thing that interferes with viral replication in mammalian cells (10). they're secreted from inflamed cells and spark off an innate immune reaction that promotes now not best cytokine production but additionally herbal killer mobile features and antigen presentation.
Interferons (IFNs) — the body's first line of antiviral defense — are cytokines that are secreted by host cells in reaction to virus infection. by using inducing the expression of hundreds of IFN-inspired genes, numerous of that have antiviral capabilities, IFNs block virus replication at many ranges.
Interferons are a circle of relatives of clearly-happening proteins which are made and secreted with the aid of cells of the immune gadget (an example, white blood cells, natural killer cells, fibroblasts, and epithelial cells).

Which statement correctly describes mitotic cell division?
Answer:
Explanation:
“Although part of your question is missing, you might be referring to this full question:
Which of the following correctly describes how mitosis and meiosis are similar?
A. Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis.
B. Crossing over occurs between homologous chromatids during both mitosis and meiosis.
C. Both mitosis and meiosis produce diploid daughter cells.
D. Both mitosis and meiosis produce genetically identical daughter cells.”
The statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”.
Mitosis and Meiosis both are classified under cell division that tends to take place in humans and certain other animals. Both Mitosis and Meiosis have both differences and similarities in the way they result in new cells with varying goals and slightly different outcomes. Some of the similarities between meiosis and mitosis are:
During both mitosis and meiosis, cells must duplicate their DNA and pull them apart into 2 sets and further place the sets on each end of itself and then divide down the middle part
Both meiosis and mitosis results in fresh new cells depending on the genes of their parent cells
Thus, we can conclude that the statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”. Hence, option A is the correct answer.

the three steps that are required for dna replication are
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
The three steps that are required for DNA replication are initiation, elongation and termination.
What is DNA replication ?The process in which DNA of a cell under go duplication to produce two copies during S-phase of cell cycle called as DNA replication.
It involves 3 steps such as initiation step where the origin of replication of DNA molecule undergo unwinding into two DNA strands.
An incomplete unzipping by forming replication fork is created is catalyzed by the helicase enzyme.
Secondly in elongation step the DNA polymerase enzymes make the complementary sequence against each parent template strand.
It is an unidirectional, one strand which is synthesized in a continuous manner called leading strand, the strand which is synthesized in a discontinuous manner called lagging strand with Okazaki fragments.
Termination occurs in the last step, when the parent molecule has been completely replicated.

how do you propagate trees
Answer:
The simplest method of propagating a tree vegetatively is rooting or taking cuttings. A cutting (usually a piece of stem of the parent plant) is cut off and stuck into soil.
Remove any flowers or fruit on the cutting. Trim the stem to just below where the bottom most leaf meets the stem. On each of the leaves on the stem, cut off half of the leaf. Put the end to be rooted.
True or False: Microbiomes are found only within the body of a host, which may be animal, plant, fungal, or even protist.

Habitat fragmentation
Answer:
Increased pollution is your answer!
Explanation:
Increased pollution is your answer because:
1. ⇒ Burning of mostly anything creats, and all the materials in the forest are one of those materials that will create smoke. And smoke is made out of carbon dioxide, and other poisonous gases that are very bad for our atmosphere.
2. ⇒ The damage from the fire will also cause a lot of damage to the trees and plants. That is very bad because trees are very important for our environment, in their leaves, they have a chemical called chlorophyll, this chlorophyll absorbs sunlight and turns it into oxygen. Not only sunlight is needed, there is also, water, nutrients needed.
