Unpasteurized milk or milk products can result in food-borne illnesses.

What are foodborne illnesses?

Foods can be contaminated by a wide range of disease-causing microbes, leading to a wide range of foodborne diseases, commonly known as foodborne sickness or food poisoning.

Over 250 foodborne illnesses have been uncovered by researchers. Numerous bacteria, viruses, and parasites are to blame for the majority of them, which are infections. Foodborne illnesses can also be brought on by toxins and chemicals contaminating foods.

Foodborne illnesses frequently cause nausea, vomiting, stomach cramps, and diarrhea. The symptoms of many foodborne infections, however, may vary. Sometimes, foodborne infections can have severe symptoms, and some of them can even be fatal. A foodborne disease may affect anybody, but certain people are more susceptible to getting one.

The majority of people who contract a foodborne disease recover on their own, but those who experience severe symptoms should visit a doctor.

Therefore, unpasteurized milk or milk products can result in food-borne illnesses.

Gel electrophoresis is used for the separation of genetic material present in the cell such as DNA, RNA and even proteins. Thus, the correct option is A.

What is Gel electrophoresis?

Gel electrophoresis is a technique which is used to separate the genetic material such as DNA fragments, RNA and proteins on the basis of their size and charge. Gel Electrophoresis involves running an electric current through a gel containing the molecules of interest in it.

The principle of Gel electrophoresis is that the DNA or protein sample to be separated is loaded on to a porous gel placed in an ionic buffer. On the application of electric charge, each of the molecules having different size and charge will move through the gel at different speeds and therefore separates out.

Therefore, the correct option is A.

If a mutation occurs such that splicing does not remove one of the introns in a gene, what effect will this have on the protein encoded by that gene

Answers

Translation will continue, but it is likely that a nonfunctional or aberrant protein will be made as a result of this effect.

Mutation is described as the alteration in the genetic sequence caused by varying effects. Diseases and exposure to dangerous materials or elements (like x-rays) can cause mutation.

However, when alteration in a genetic sequence is effected such that the splicing that occurs prior to mRNA translation, does not remove a segment of a DNA or RNA molecule (which does not code for protein), and this will disrupt the gene sequence. Although, translation will continue, but the protein synthesised will be a nonfunctional or abnormal one.

Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles. Ribosomes are not enclosed within a membrane but are still commonly referred to as organelles in eukaryotic cells. Membrane-bound organelles. Membrane-bound organelles are cellular structures that are bound by biological membrane. Examples of membrane-bound organelles are nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes and vacuoles.

Have a great day friend! :D

Answer:

Organelles play an important role in a variety of cell processes. The nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles are all organelles found in animal cells. Although ribosomes are not surrounded by a membrane, they are nonetheless referred to as organelles in eukaryotic cells.

Explanation:

ORGANELLESAn organelle is a specialized subunit of a cell that has a defined role in cell biology. The name organelle stems from the idea that these structures are sections of cells, similar to how organs are parts of the body, therefore the diminutive suffix -elle. Organelles are either independent lipid bilayer-enclosed functional units (also known as membrane-bound organelles) or spatially distinct functional units without a lipid bilayer surrounding them (non-membrane bound organelles). Although most organelles are functional units within cells, some functional units that extend outside of cells, such as cilia, the flagellum and archaellum, and the trichocyst, are often referred to as organelles.

describe the features of the endocrine system for control in the example given.

- endocrine gland
-negative feedback mechanism
-produce hormone -> travel via blood-> target specific cells organs

Please expand these bullet points

Answers

Answer:

The endocrine system is a major system in the body composed of glands that secrete hormones, which are substances produced by the body to stimulate an organ or group of cells. The endocrine system controls essential bodily functions, which include movement, sexual development, sensory perception, and even growth.

Explanation:

Hormones are chemicals that are produced by the glands in the endocrine system and coordinate distinct bodily functions by carrying important messages throughout the body. They send signals to receiver cells in organs, muscles, and tissues.

Role of Hormones

Hormones have very essential roles in the body, as they regulate metabolism, growth, and sex development. For example, testosterone and estrogen are sex hormones that are released in the body to initiate sex development during puberty. The rate at which these hormones are produced and released must also be highly controlled for optimal development and growth. Hormones also control levels of hunger or exhaustion. Overall, they are very important in telling the body what to do and how to do it.

Function of Hormones

As previously mentioned, hormones serve several important functions throughout the body. They are responsible for the function of organs, in addition to controlling how the body stores and uses energy. Hormones only target specific organs or cells: for example, thyroid-stimulating hormones are released by the pituitary gland, and only target the thyroid gland. Some hormones can affect several kinds of tissues at once; for instance, the thyroid hormone, produced by the thyroid gland, can affect several bodily functions, such as heart rate and metabolism.

3. Oxygen increase weathering leads to formation of soil.

Factors made the land a place where the first land plants could thrive are abundant sunlight for photosynthesis  and new, nutrient-rich soil made of cyanobacteria as well as deteriorating of rock.

Cyanobacteria were the first photosynthesizing organisms that lived on Earth 3 billion years ago. Cyanobacteria live anywhere on the earth where light and moisture is available i.e. in the open oceans, lakes and streams, in soils, hot and cold deserts, hot springs and salty water.

Increased levels of oxygen in the atmosphere due to photosynthesis caused rates of weathering to increase which help in the formation of soil. Oxygen directly take part in the chemical weathering of rocks through the process of oxidation. In this process, oxygen reacts with a substance present in the rock and forms oxides which will result in weathering.

Answers

Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These  characteristics are passed on to their offspring.

According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.

Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.
