Answer:
Bacteria
Explanation:
Hence, abiotic elements determine how organisms survive in an ecosystem. The main difference between biotic and abiotic is that biotic refers to all living things of an ecosystem while abiotic refers to all the non-living, physical and chemical things of an ecosystem.
Sunlight, rocks, and soil are all non-living.
The only biotic component mentioned is bacteria. Living things or their impacts are referred to as biotic factors. Single-celled creatures known as bacteria can live alone or in colonies.
They may be found almost anywhere, including the soil and the human body. All three kingdoms of life, Archaea, Bacteria, and Eukarya, contain bacteria that can reproduce. The terms "soil," "sunlight," and "rocks" all refer to abiotic elements, or nonliving parts of the environment.
Minerals, organic substances, gases, liquids, and living things all make up soil. Photosynthesis and other biological activities require sunlight, a type of energy that the sun radiates. Rocks are unbreakable, inorganic objects made of minerals.

There are more than 300,000 species of plants that have been identified thus far in the world today; many new species are being discovered each year. In addition to providing most of the oxygen for land animals, plants do many other things for us. you will research the Internet and use reliable and credible scientific websites to investigate a specific plant species and choose a way (other than providing oxygen) that plants are useful to humans. [NOTE: Hot topic plants like Marijuana and Opium are off limits and cannot be discussed.]
Writing a full paragraph (a 150-words minimum) for your initial blog post discussing a specific species of plant and the benefit you chose. Be sure to describe what type of plant it is. Where is it found? How does it impact humans or other species? What role does it play in the ecosystem, etc.?
Answer and Explanation:
We can mention the advantages of the plants of the Fabaceae family, also known as legumes, such as beans, soybeans, peanuts and peas. First, we must mention how these plants have high nutritional values providing high levels of iron and nitrogen that are essential elements for human health. However, a benefit that these planats produce and that is important on a worldwide scale is the fixation of nitrogen in the soil. All living beings need nitrogen in their bodies, since nitrogen is a primary element in the composition of nucleic acids and proteins. Animals are able to ingest nitrogen from the vegetable diet, but vegetables cannot absorb nitrogen from the atmosphere or nitrogen from the soil, because they are not in molecular forms that plants can absorb. To reverse this, farmers put chemical fertilizers on the plantations, but these fertilizers pollute the environment intensely. It is in this scenario that the plants of the Fabaceae family are important. This is because these plants are able to associate with bacteria that can capture atmospheric nitrogen and place it in the soil, in the molecular form that all plants can absorb. This allows plants to have the necessary nutrients for their growth, reduces environmental pollution, decreases spending on agricultural production, promotes correct levels of nitrogen for human consumption and allows agricultural products to be healthier.
Assume that you discover a new human gene that you believe is located on the Y chromosome although not in the region (pseudoautosomal) of the Y that is homologous with part of the X chromosome. How would you map this gene with respect to the other genes on the Y chromosome
Answer:
by performing a bioinformatic analysis in order to discover Y chromosome-linked mutations associated with defective phenotypes. In this case, it is expected to discover two or more loss of function mutations located in the coding region of the target gene on the Y chromosome in different males, and then associate such mutations with altered phenotypes caused by the inactivation (loss of function) of this gene
Explanation:
The genes located on the Y chromosome exhibit a uniparental mode of inheritance (i.e., these genes are only transmitted from father to their sons). This situation makes difficult to map the target gene since recombination does not occur for genes that are only located on the Y chromosome, hampering the development of a linkage map containing this gene. In this case, it is possible to directly associate genetic mutations located at the same genomic region (locus) on the Y chromosome with a particular altered phenotype in males carrying these mutations, which can be in principle associated with the inactivation of the target gene (loss of function mutations) in these individuals.

Explain how prokaryotes (note that this is for prokaryotes and NOT eukaryotes) control gene expression.
Answer:
By Controlling transcription
Explanation:
Prokaryotic cells regulate their gene expression by controlling the amount of transcription. This is the only way of regulating the gene expression.
Unlike the prokaryotic cell, in eukaryotic cell, different compartments were formed for carrying out different cellular processes. Later on, transcription and translation were physically separated and were carried out in two different cellular compartments
what would never be part of an mRNA strand?
Answer:
Uracil
Explanation:
Thymine would never be part of an mRNA strand.thus, option A is correct.
What is mRNA?Messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).
It was also known that there are only four nucleotides in mRNA: adenine (A), uracil (U), guanine (G), and cytosine (C). Same three nucleotide base is also present in the DNA except thymine. Thymine is replaced with uracil in case of RNA. thus option A is correct.

Which of the following are functions of the reproductive organs in animals?
I. Produce sperm
II. Support the body
III. Protect the internal organs
IV. Make the eggs
I and II
II and IV
I and IV
II and III
Answer:
c
Explanation:
I and IV are the functions of the reproductive organs in animals.
What are Reproductive organs?
The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.
The fertilized egg is then transferred to your uterus, where the lining has expanded due to the regular hormones produced during your menstrual cycle (also called your reproductive cycle).
The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur. The female reproductive system also creates sex hormones that keep your menstrual cycle regular.
Therefore, I and IV are the functions of the reproductive organs in animals.

Scientists believe Polar Bears have evolved from a group of Brown Bears that became an isolated population during a time when the Earth's climate began cooling down.What are some adaptations that make Polar Bears different from Brown Bears and what do you think caused the adaptations to occur?
Answer:
One adaptation is white fur. There was probably one white cub born to a brown bear mother, and the fur helped camouflage it for safety and later, hunting. This bear would have been more successful in hunting in the arctic, so it was more likely to reproduce and pass on the white fur genes. A second adaptation is the long claws of brown bears that are used for digging through vegetation would have shortened to be safer on ice. Polar bear paws also have little sticky bumps on their paws for gripping ice.
A third adaptation is that polar bears don't hibernate in winter. In winter, there is a lot more food available to them, so they need to stay awake. A fourth adaptation is their hair is also now water repellent, because most of their food comes from the sea. A fifth adaptation is in their digestive system. Polar bears don’t digest carbohydrates as well as brown bears, because their diet has much more fat than anything else. Polar bears hunt seals and can convert the blubber into fat for their bodies to live off of when food is scarce.
