The immune system and the nervous system maintain extensive communication, including 'hardwiring' of sympathetic and parasympathetic nerves to lymphoid organs. Neurotransmitters such as acetylcholine, norepinephrine, vasoactive intestinal peptide, substance P and histamine modulate immune activity.

Answer:

The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.

Explanation:

Factors that affect evolution.

As per the question the evolution is a gradual process that includes the changes in the body of the organisms thereby making them more stronger and dynamic than others. The 4 features that affect evolution are mutations, natural selection, genetic drift, and gene flow.

The answer is thus are a major factor that leads to evolution in specie.

Answer:

DNA

Explanation:

Bacterial Transformation was discovered as a natural phenomenon 1928 by Griffith et al. Later in 1944 scientists actually identified the transforming principle as DNA. It is a process of horizontal gene transfer in bacteria. It involves transfer of DNA fragment to a live bacteria through intact cell boundary.

Answer:

DNA

Explanation:

transfer of DNA fragment to a live bacteria through intact cell boundary.

Answer:

Explanation:

The cell is the most basic unit of life. Similar cells together form tissues. Similar tissues together form organs. Organs work together in organ systems. Organ systems form complex organisms. Because living things are diverse, taxonomy was created to group organisms into categories and to understand their evolutionary relationships.

Answer:The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

Explanation:Cells are divided into several compartments, each with a characteristic structure, biochemical composition, and function.

These compartments are called organelles. They are delimited by membranes composed of phospholipid bilayers and a number of proteins specialized for each type of organelle.

All eukaryotic cells have a nucleus surrounded by a nuclear envelope, and a plasma membrane that borders the whole cell.

Most eukaryotic cells also have endoplasmic reticulum, a Golgi apparatus, lysosomes, mitochondria, and peroxisomes.

Answer:

It must have a closed switch.

Explanation:

The current cannot flow through the full circuit if the switch is open, therfore the light won't switch on. However, if the switch is closed, the current can run through the circuit and the light bulb will switch on.

Answer:

D giardiasis is the correct answer :)

An example of a communicable disease is giardiasis, which is in option D. Giardiasis is an example of a communicable disease. It is caused by a microscopic parasite called Giardia lamblia.

This disease affects the digestive system, causing symptoms such as diarrhea, abdominal cramps, bloating, and nausea. It is typically transmitted through the ingestion of contaminated food or water that has been contaminated with the parasite. Chronic respiratory disease includes conditions such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis, which are usually caused by long-term exposure to irritants or genetics and are not directly communicable.

Answer:

The major difference between Gram-positive and Gram-negative peptidoglycan involves the thickness of the layers surrounding the plasma membrane. Whereas Gram-negative peptidoglycan is only a few nanometers thick, representing one to a few layers, Gram-positive peptidoglycan is 30–100 nm thick and contains many layers.

An arrangement of all the chromosomes of a diploid cell is called a kayrotype

An arrangement of all the chromosomes of a diploid cell is called a karyotype is the overall look of all the chromosomes in a species or an individual organism's cells.

A karyotype is a eukaryotic cell's nucleus' number and arrangement of chromosomes. The phrase is also used to refer to a species or an individual organism's entire set of chromosomes.

Each diploid cell in humans contains 46 chromosomes. There are 22 pairs of autosomal, or non-sex, chromosomes and two chromosomes that determine sex among them. A diploid cell has 2n total chromosomes, which is twice as many as a haploid cell's total chromosomes (n).

Therefore, a karyotype is the overall look of all the chromosomes in a species or an individual organism's cells, primarily their sizes, numbers, and shapes.

Answer:

(b) a distant luminous object travels rapidly towards an observer.

Explanation:

Blueshift is observed when a distant luminous object travels rapidly towards an observer. The correct option is B.

The displacement of an approaching celestial body's spectrum toward shorter wavelengths is known as blueshift.

When an object moves away from us, the light it emits is known as redshift; when an object moves towards us, the light it emits is known as blueshift.

The blue and red shift of stars cannot be seen with the bare eye. There are several reasons for this.

First, even for an object moving at thousands of kilometers per hour, the effect is minor, with only a slight change in hue.

Red light, with both the longest wavelength, is at one end of the spectrum.

The shortest wavelength is blue or violet light. White light is a blend of all the colors in the color spectrum. It has every color of the rainbow.

Thus, the correct option is B.

Answer:

your answer is B. Habitat Loss

Explanation:

What is the #1 cause for the loss of biodiversity?

Habitat destruction

Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.

Habitat loss and overexploitation, driven by our rapid population growth and unsustainable consumption patterns, are the primary causes of biodiversity loss which is now happening up to ten thousand times faster than for millions of years before.
