Identify the natural processes that occur on the earth's surface to make and destroy rocks.
Answers
Answer:
You learned about the three rock types: igneous, sedimentary, and metamorphic. You also learned that all of these rocks can change. In fact, any rock can change to become any other type of rock. These changes usually happen very slowly. Some changes happen below Earth’s surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form, and how they change.
The figure below shows how the three main rock types are related to each other (Figure below). The arrows within the circle show how one type of rock may change to rock of another type. These are the processes that change one rock type to another rock type.

Answers
Answer:
2:2
Explanation:
so we have the father as Bb and the mom as AB, by using a Punnett square we get so we have AB, Ab, BB, Bb types
we have 2 ut of 4 chances of getting A AND 2 OF GETTING B, so ratio is 2:2

although farmers once used only organic fertilizers to replenish nutrients in the soils, some have been replaced with synthetic fertilizers. Although synthetic fertilizers keep nutrient levels high and increase crop yields, they can have an effect on the environment. Which of the following would most likely lead to a ban of synthetic fertilizers?
A. Synthetic fertilizers help prevent the spread of diseases.
B. Synthetic fertilizers are less expensive than organic fertilizers.
C. Synthetic fertilizers increase the potential for environmental pollution.
D. Synthetic fertilizers provide nutrients, like nitrogen that can disrupt nutrient cycling.
Answers
Answer: C. Synthetic fertilizers increase the potential for environmental pollution.
Explanation:
A fertilizer is a material which when applied to soil ,supply one or more plant nutrients essential to the growth of plants.
Fertilizers could be organic ( obtained from nature ) or could be synthetic ( made artificially in labs).
Though synthetic fertilizers such as urea keep nutrient levels high and increase crop yields but they also kill beneficial microorganisms in the soil that convert dead human and plant remains into nutrient-rich organic matter. The non biodegardable synthetic fertilizers seep into groundwater and increase its toxicity, causing water pollution.
Synthetic fertilizers damage the natural makeup of the soil. Plants that grow in soils which use synthetic fertilizers are deficient in iron, zinc, carotene, vitamin C, copper and protein.

Answer:
meiosis
Explanation:
meiosis is used to produce gametes for sexual reproduction
Answer:
Meiosis, and female and male
Explanation:
Sexual reproduction is a reproduction that requires a male and a female of the same species to contribute genetic material. Special cells called gametes are produced through meiosis, which halves the number of chromosomes in each resulting cell. These cells are called haploid gametes.

Why are some pathogenic bacteria able to make toxins?
Answers
The relationship between a host and a pathogen is dynamic, since each modifies the activities and functions of the other. The outcome of such a relationship depends on the virulence of the pathogen and the relative degree of resistance or susceptibility of the host, due mainly to the effectiveness of the host defense mechanisms. Staphylococcus aureus, arguably the most prevalent pathogen of humans, may cause up to one third of all bacterial diseases ranging from boils and pimples to food poisoning, to septicemia and toxic shock. Electron micrograph from Visuals Unlimited, with permission.
The Underlying Mechanisms of Bacterial Pathogenicity
Two broad qualities of pathogenic bacteria underlie the means by which they cause disease:
1. Invasiveness is the ability to invade tissues. It encompasses mechanisms for colonization (adherence and initial multiplication), production of extracellular substances which facilitate invasion (invasins) and ability to bypass or overcome host defense mechanisms.
2. Toxigenesis is the ability to produce toxins. Bacteria may produce two types of toxins called exotoxins and endotoxins. Exotoxins are released from bacterial cells and may act at tissue sites removed from the site of bacterial growth. Endotoxins are cell-associated substance. (In a classic sense, the term endotoxin refers to the lipopolysaccharide component of the outer membrane of Gram-negative bacteria). However, endotoxins may be released from growing bacterial cells and cells that are lysed as a result of effective host defense (e.g. lysozyme) or the activities of certain antibiotics (e.g. penicillins and cephalosporins). Hence, bacterial toxins, both soluble and cell-associated, may be transported by blood and lymph and cause cytotoxic effects at tissue sites remote from the original point of invasion or growth. Some bacterial toxins may also act at the site of colonization and play a role in invasion. Acid-fast stain of Mycobacterium tuberculosis, the agent of tuberculosis (TB). The bacteria are the small pink-staining rods. More than one-third of the world population is infected. The organism has caused more human deaths than any other bacterium in the history of mankind. Although its ability to produce disease is multifactorial, it is not completely understood. American Society of Microbiology, with permission.
