Answer:

neutrophils are responsible for destroying or neutralizing pathogens

Some organisms have genes that improve their ability to survive and reproduce. If the gene also help their offspring survive and reproduce, then frequency in gene in population get increase.

A gene is the basic physical and functional unit of heredity. Genes are made up of DNA and each chromosome contains many genes.

Throughout the individual lives, their genomes interact with their environments to cause variations in traits which help an organism to adapt better to the environment. These changes which help the organism's survival are selected and passed on to next generation.  The genes help in increasing the fitness of the organism and thus the gene frequency changes.  . The frequency of these gene increases as they are selected favourably.

Explanation: Degrees Celsius to kelvins

Answer:

Celsius to Kelvin

The Celsius and Kelvin scales have the same size degree, but have different 'zero' or starting points. The freezing point for water is C and 273 in the Kelvin scale.

Answer: Because, if there was erosion, the earth could not get in touch with inner land, so erosion can happen on coastlines, rivers, canyons, or any thing that has a body of water.

The one difference between RFLP and PCR is that RFLP requires larger samples of DNA than PCR requires.

Restriction fragment length polymorphisms, or RFLPs, are differences among individuals in the lengths of DNA fragments cut by enzymes.

Polymerase chain reaction, or PCR is a technique in molecular biology for creating multiple copies of DNA from a sample.

Fever

Explanation:

Symptoms can last for seven days

Six hours to six days after infection, symptoms typically appear and continue for four to seven days. On the other hand, some people feel symptoms for a few weeks after infection, while others do not.

Infection with salmonella is typically brought on by ingesting raw or undercooked meat, poultry, eggs, or egg products, as well as by consuming unpasteurized milk.

The incubation period—also referred to as the latency period—can last anywhere from six hours to six days.

In addition to causing diarrhea, the acute inflammatory reaction can result in mucosal damage and ulceration. The germs have the potential to spread from the intestines and result in systemic illness.

Diarrhea, fever, and cramps are the most common symptoms of Salmonella infection.

Two control systems of the body

Endocrine and Nervous

Endocrine and nervous system similarities

-Work together to maintain homeostasis

-Release ligands (chemical messengers) that bind to cellular receptors on particular target cells

Endocrine and nervous system differences

Endocrine system: -Transmits hormones through blood

-Targets any cell in the body with the correct receptor

-Very widespread

-Exhibits longer reaction times and has longer-lasting effects

Endocrine System

-Composed of ducts and glands that synthesize and secrete hormones

-Hormones are released into the blood and transported throughout the body

Endocrine system regulation growth and development

-Changes measured from birth to puberty

-Hormones help regulate embryonic cell division and differentiation

-Hormones regulate metabolism

How does the endocrine system maintain homeostasis or blood composition and volume

-Hypothalamus

-Hormones regulate blood solute concentrations (ex glucose ions)

-Hormones regulate blood volume, cellular concentration, and platelet numbers

The endocrine system controlling digestive processes

-Trigger digestion when food is in the stomach

-Hormones influence secretory processes and movement of materials in the digestive tract

Endocrine System controlling Reproductive Activities

-Make sure sperm and egg make it to each other

-Hormones affect the development and function of the reproductive system and the expression of sexual behavior

Endocrine Glands

Contain epithelial tissue that makes and releases hormones within a connective tissue framework

Endocrine Organs

-Glands with solely endocrine functions

-Ex: Pituitary, pineal, thyroid, parathyroid, and adrenal

Endocrine Cells

-Found in clusters in organs with another function

-Examples in Hypothalamus, Thymus, Heart, Stomach, Liver, Pancreas, Small Intestine, Adipose Connective Tissue

-Pancreases is not an endocrine gland, but it does release hormones

Replicability is the repetition of the experiment by other researchers who get the same results as the original experiment. B) Other students repeat the same procedure on other potatoes.

Following the scientific method, an experiment needs to be replicable.

Replication refers to the need of repeating a research study, under different situations, different subjects, and with different researchers to determine the safety of the original findings and their possibility of generalizing them to other situations and participants.

Replicability is the possibility of carrying out the same experiment by other researchers. When repeating the experiment, results should be the same, or with a minimal variation. Results heterogeneity should be minimal.

Option B is correct. Have other students repeat the same procedure on other potatoes.

The exact same experiment will be repeated by different students -researchers- and their results should be the same as the ones of the first student -potatoes are 40% water-.

Answer:

1. Viruses are unable to respire

2. Viruses are unable to excrete

Explanation:

Both respiration and excretion are essential parts of the life processes of living organisms. Viruses, however, are unable to perform these processes and are therefore considered non-living.

A variation that results in increased fitness is more likely to be passed on  because the individual will reproduce. thus option B is correct.

Genetic diversity is endlessly possible as a result of sexual reproduction. In other words, sexual reproduction produces genetically distinct offspring. They are different from one another as well as from their parents.

Variation will be passed on through reproduction. reproduction results in genetic variation which increase the chance of survival of new organisms.
