Select the correct answer from each drop-down menu. Bile juices help in the breakdown of fats. An injury to the may cause a decrease in the production of bile juices. This decrease in bile juices may lead to decreased production of .
Answer:
Decreased production of energy.
Explanation:
Decrease in bile juices may lead to decreased production of energy from eating of food having fats because our body has no ability to absorb fat-soluble vitamins and fatty acids. Bile juices is responsible for the absorption of fat-soluble vitamins and fatty acids which is then transported to the cell for producing energy that is required by our body for different processes. Fats have more energy than carbohydrates and protein so if there is no bile juices are present so it break down does not occurs.

VNTRs are highly conserved in human populations. d. PCR amplification generates large numbers of linear DNA fragments. e. RNA molecules can be used as hybridization probes in Southern blot analysis. Separate your answer(s) with a comma, and enter only the letter(s) of your choice(s
Answer:
b. Antibodies are used for Northern blot analysis.
c. VNTRs are highly conserved in human populations.
Explanation:
The northern blot technique is used in molecular biology laboratories for detecting specific RNA molecules in a sample of RNA derived from a particular cell/tissue. Antibodies can be detected by the enzyme-linked immunosorbent assay (ELISA). In ELISA, antigens are used to detect specific antibodies: the addition of the antigen produces a positive reaction i.e., formation of the antigen-antibody binding complex. Subsequently, a second antibody with a particular marker is added to bind with the complex, thereby producing a change in the color and thus evidencing the presence of the target antibody in the sample. On the other hand, the variable number of tandem repeats (VNTR) are short sequences (around 20 to 100 bp) whose number of repetitions varies at specific loci in the genome of many organisms, including humans. Since VNTR sequences exhibit variation in length between individuals of the same species/population, they are widely used as molecular markers to identify individuals, QTL (quantitative trait loci) mapping, establish phylogenetic relationships among individuals/cultivars/lines, etc.

What tool do meteorologists Use to analyze particle movement within storms?
Describe the impact of human activities on natural resources;
consider energy, mineral, forest, marine, over population and over fishing.
Answer:
As the human population has grown, the need for more land has caused an increase in the cutting down of forest lands for habitation and farming. The result has been an increase in soil erosion, an increase in species extinction from habitat loss, and a reduction of oxygen supplied by the trees, as well as lower amounts of carbon dioxide being removed from the atmosphere. Industrial and personal use of fossil fuels has dramatically increased the amount of air pollution in the atmosphere while systematically using up the supply of the non-renewable resources such as coal, oil and natural gas

Answer:
Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.
Explanation:
Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

What is a cell?
The smallest unit of life is a cell. There are biomolecules in it. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.
Prokaryotic cells are the most basic types of cells; they are only seen in unicellular organisms, do not engage in cell division, and lack real cell organelles and a nucleus, instead having DNA coiling up in the cytoplasm.
Eukaryotic cells are higher cells that contain cell organelles and have the capacity to carry out a variety of intricate tasks required by big organisms.
Thus, Cell signaling is a method of communication between or within cells, and a change in a cell's activity is conveyed as a signal that may set off a chain of events so that the body can respond appropriately.

Which do solar flares and coronal mass ejections have in common? Select the two correct responses.
A. They appear as dark spots on the sun's surface.
B. They tend to occur during minimum points in the solar cycle.
C. They are caused by the sun's changing magnetic field.
D. They are explosive events that can affect Earth.
C. They are caused by the sun's changing magnetic field.
D. They are explosive events that can affect Earth.
Explanation:
I'm sorry if it is wrong but I am almost 100% that it is correct!
Have a good one!
The solar flares and coronal mass ejections are caused by the sun's changing magnetic field. Also they are explosive events that can affect Earth. The correct options are C and D.
What is solar flare?A solar flare is a massive explosion on the Sun caused by the sudden release of energy stored in 'twisted' magnetic fields.
However, not all solar flares are safe. While the Earth's magnetic field protects us from solar radiation, the sheer electromagnetic power of a flare disrupts power grids, internet connections, and other communication devices.
Ejections occur at varying rates depending on the phase of the solar cycle, ranging from about 0.2 per day near the solar minimum to 3.5 per day near the solar maximum.
Coronal Mass Ejections are large plasma and magnetic field expulsions from the Sun's corona.
The sun's changing magnetic field causes solar flares and coronal mass ejections. They are also explosive events that can have an impact on Earth.
Thus, the correct options are C and D as per the given scenario.
