How many major categories are fossils grouped into?
Answer:
Fossils are remnants or impressions of ancient organisms that are naturally preserved in stone. While there are hundreds of fossil types, they are often grouped into two major categories: Body fossils, which are the preserved remains of plants and animals; and Trace fossils, which are records of an animal’s behavior, such as footprints.
Explain tectonic movement, how it happens, and what it does over time
Tectonic shift is the movement of the plates that make up Earth's crust. ... As Earth's mantle heated and cooled over many millennia, the outer crust broke up and commenced the plate motion that continues today. The huge continent eventually broke apart, creating new and ever-changing land masses and oceans.
Decide if the following statements best describe map-based genome sequencing, best describe whole-genome shotgun sequencing, or apply equally to both sequencing methods.
a. starts with libraries of large, overlapping DNA fragments
b. starts cloning and sequencing of short, random DNA fragments
c. uses genetic recombination data to help arrange sequences correctly
d. requires sequences to be annotated after contig assembly
e. requires chromosome fragments to overlap for contig assembly
f. requires subcloning of large fragments into smaller clones for sequencing
g. is a better approach for repetitive sequences
1. Map-based genome sequencing
2. Whole-genome shotgun sequencing
3. Both sequencing methods
Answer:
1. Map-based genome sequencing: a; c; f; g
2. Whole-genome shotgun sequencing: b
3. Both sequencing methods: d; e
Explanation:
Map-based genome sequencing is a method that makes use of a reference genome sequence in order to determine the relative position of the DNA fragments before they are sequenced. This method is useful to determine the position of repetitive DNA fragments (for example, duplicated genes, repetitive non-coding regions, etc.) and Transposable Elements. Therefore, map-based genome sequencing is a suitable approach for large genomes (which are usually composed of repetitive sequences). On the other hand, in whole-genome shotgun sequencing, DNA sequences are obtained before the correct order of these DNA fragments is known. In this method, the genome is fragmented randomly into small DNA sequences (between 100 and 1000 base pairs), which are subsequently sequenced through the chain-termination sequencing approach (i.e., Sanger sequencing) and finally ordered by using bioinformatic tools that assemble overlapping reads.
12. Individuals with Type O blood are able to produce both Anti-A and Anti-B antibodies, while individuals with Type AB blood produce neither of these antibodies. Explain why this is the case. How does this relate to the idea that people with Type AB blood are often referred to as universal recipients for transfusions
Answer: Blood group O individuals are able to produce Anti- A and Anti- B and are often referred to as UNIVERSAL DONORS, while blood group AB individuals produces none and are often referred to as UNIVERSAL RECIPIENTS
Explanation:
Two antigens, type A and type B, occur on the surfaces of the red blood cells in a large proportion of human beings. These antigens are referred to as agglutinogens because they often cause blood cell agglutination during blood transfusion. Because of the way these antigens are inherited, people may have neither of them on their cells , they may have one or they may have both simultaneously.
When type A antigen and type B antigen is not present in an individuals reb blood cell as seen in blood group O, antibodies known as Anti-A and Anti- B develops in the plasma. This is because small amounts of type A and type B antigens enter the body through food, bacteria and other ways and they initiate the development of anti A and Anti- B antibodies in their plasma.
Furthermore, individuals with blood type AB has antigen A and B on their red blood cells and therefore do not develop antibodies A and B in their plasma. This makes them universal recipient as their blood do not discriminate any ABO blood group during blood transfusion.
A few years ago, the labels from one class section's experimental treatments plants fell off in the greenhouse and got swept away! One group was the only group in the section to test the effects of indole acetic acid (IAA) on bean plants. The IAA group applied lanolin paste to one side of their bean stems. What should they look for in order to identify their experimental plants from other groups
Answer:
The group needs to find signs of apical dominance, growth in response to light, vascular tissue differentiation, formation of lateral and adventitious roots, etc.
Explanation:
Lanolin is a solvent used to study physiological processes in plants by diluting hormone growth regulators (in this case, indole acetic acid). Indole acetic acid (IAA) is the most important auxin hormone in plants. Auxins are essential plant hormones synthesized in expanding shoot tips that move down the stem to the roots. These hormones coordinate cell division, elongation and identity during plant body development. IAA hormone is well known to regulate different plant developmental processes including, among others, apical dominance (where the central stem grows more strongly than other lateral stems), tissue differentiation, stem elongation, phototropism (growth in response to light) and gravitropism (response to gravity). For instance, under the application of IAA, it is expected that bean stems grow to imitate the response to light (phototropism) by bending away from the side where lanolin was applied.
What evidence do fossils provide for how life has changed throughout Earth's history?

if your answer is right you l get brainly
Answer:
Lupus refers to autoimmune disease in which the immune system of the body attacks its normal and healthy tissue instead of virus and bacteria. Symptoms of this disease include inflammation, swelling, and damage to the joints, skin, kidneys, heart, and lungs etc. The main cause of this disease is the environment that triggers Lupus. Chemotherapy and medications such as Nonsteroidal anti-inflammatory drugs and Antimalarial drugs etc are used for its treatment. Due to the disease's complex nature, it is often called "the of 1000 faces". In the united states there are about 16000 new cases of lupus every year. There are different kinds of lupus. This article will focus mainly on systemic lupus erythematosus (SLE), but other types include discoid, drug-induced, and neonatal lupus. Currently there is no cure for lupus, but the symptoms can be managed with care. The treatment aims to manage and prevent flare ups. The exact treatment will depend on how lupus affects the individual. Without treatment, flares can occur that may have life-threatening consequences.

What is glucagon's major role in the body?
Answer:prevent blood glucose levels dropping
Explanation:Glucagon's role in the body is to prevent blood glucose levels dropping too low. To do this, it acts on the liver in several ways: It stimulates the conversion of stored glycogen (stored in the liver) to glucose, which can be released into the bloodstream. This process is called glycogenolysis.
Definition: This is an organism's response to a stimulus developed by being taught or watching another organism. Example: how to open a soda when you're thirsty

Which type of organism is it?
A. logistical
B. an r-strategist
C. a K-strategist
D. density dependent
THE ANSWER IS....
Answer:
B. an r-strategist
Explanation:
R-strategist (also known as r-selected species) refers to species whose population growth is based on the maximum reproductive capacity of the individuals under optimum environmental conditions (i.e., the biotic potential). These species are well known to produce numerous offspring and they show exponential population growth. The most common features of the R-selected species are 1-high reproductive rate, 2-rapid development, 3-early reproductive age, 4-small size, 5-short life spans, 6-poor competitive ability, and 7-high mortality. Some examples of r-selected species include rabbits, mice, marine invertebrates (e.g. jellyfish), weeds, bacteria, etc.
Answer:
Thanks so much for giving the answer!
It is r-stragery though.
k-stratergy produce fewer offspring slowly- such as an elephant.
r-strategey produce offsping rapidly- such as a (nasty) fly.
