according to theory, the fossils found in the lower layer of rocks are _____ than those found at a higher layer
younger
tougher
older
same age
According to theory, the fossils found in the lower layer of rocks are older than those found at a higher layer. Hence, option C is correct.
What are fossils?Any surviving remains, impression, or evidence of a once-living thing from a previous geological epoch is referred to as a fossil. The majority of fossils are created when a living thing (such as an animal or plant) dies and is swiftly buried by sediment (such as mud, sand, or volcanic ash).
Shells, bones, animal or microbe imprints in stone, exoskeletons, items preserved in amber, petrified wood, coal, hair, oil, and DNA traces are a few examples of fossils.
As fossils get older, they get buried more down in the soil, older fossils are found in the lower layer, while younger fossils are found in the upper layer. Therefore, option C is correct.

what is somatic cell ?Somatic cells are involve in the growth and development of an organism required for repair and regeneration
Somatic cells participate in mitosis and contain the same set of chromosomes, these cells have a diploid set of chromosomes as compared to gametes produced by meiosis and have a haploid set of chromosomes
Somatic cells undergo mutation frequently as compared to germ cells, used for cloning by which an identical clone of an individual is produced
Somatic cell nuclear transfer is one such process where the nucleus of a somatic cell is transferred to an ovum cell. Somatic cells are used to conserve genetic information of animals.

D.
Chromosomes are arranged in 20 distinct pairs in the human body.
Please select the best answer from the choices provided
A
B
C
D
Answer:
B. Chromosomes are threadlike structures that carry genetic information
Explanation:
Normally developed humans carry about 46 chromosomes in each cell, so A is false.
The numver of chromosomes is equal from the mother and the father, so C is false.
Chromosomes are arranged in 23 distinct pairs, so D is false.
The statement that best describes chromosomes is: Chromosomes are the threadlike structures that carry the genetic information.
What is a chromosome?It is a structure that is present in both prokaryotes and eukaryotes and is composed of nucleic acid (DNA) and proteins. It is responsible for genetic information.
Facts about chromosomes:Humans have 46 chromosomes in all somatic cells, and the reproductive cells except in the sperm and ova, which are haploid with 23 chromosomes only.

Lactose intolerance means that you cannot break down the sugar lactose. It is caused by DNA mutations that lead to a nonfunctional lactase enzyme. Does this disorder affect your ability to digest other sugars beside lactase?
Answer:
No
Explanation:
Lactose intolerance only affects your ability to break down lactose.
Other sugars like saccharose or maltose are hydrolised by their own specific enzymes saccharase for saccharose and maltase for maltase. Therefore, the ability to digest other sugars beside lactase won't be affected in lactose intolerance.

Multicellular organisms use mitosis for growth, development, and
A . apoptosis
B . repair
C . reproduction
D . interphase
Multicellular organisms use mitosis for growth, development, and repair and they also play the role of decomposers. Thus, option B is correct.
What is the key role of decomposers in the nitrogen cycle?Decomposer serve a key role in the nitrogen cycle primarily because they break down plant and animals waste and release nitrogen into the atmosphere.
These processes has been based on the single principle: the difference in density between the components of the mixture. They are often used together to separate heterogeneous mixtures of two types as liquid + solid and immiscible liquids. In this case we have what mixture is the sediments of stones and the water that through the sieve will separate one from the other.
Mining has a large impact on the environment because minerals are contained within the Earth. The long term effects of mining include acid drainage, erosion and dust emissions.
Therefore, Multicellular organisms use mitosis for growth, development, and repair and they also play the role of decomposers. Thus, option B is correct.

Staph infections caused by the bacterium staphylococcus aureus are increasing in frequency and are more difficult to treat with antibiotics many staph infections are now caused by mrsa and methicllian resistant strain of s aureus. What explains the more widespread phenomenon of mrsa prevalence in staph infections
Answer:
This question lacks options, options are: A) Vaccines for MRSA have become not effective because of changes to human immune systems. B) The presence of antibiotics induced the bacterial genomes to mutate and develop resistance to the drug. C) Decreased hospital sanitation practices to save money have resulted in increased presence of resistant staph infections. D) Selective pressures by excessive antibiotic use have increased the frequency of resistant strains of S. aureus over the last few decades.The correct answer is D.
Explanation:
The susceptibility of the various germs has varied greatly in recent years. Strains that had been consistently susceptible to all antimicrobial agents for decades have now developed resistance to these classic therapies, they have the ability to rapidly develop resistance to the newer antimicrobials. Methicillin Resistant Staphylococci (MRSA) is a clear example of this situation. The mechanism that confers resistance to methicillin is complex, since the bacterium has generated a genetic variation, which is encoded in the mecA gene, by which it modifies the structure of its penicillin-binding or binding protein (PBP2a), This prevents methicillin from adhering to the place where it is going to exert the action of blocking the transpeptidase enzyme (whose function in the bacterial life cycle is to synthesize the bacterial wall).Resistance to methicillin in strains of S. aureus is a growing problem worldwide, and staphylococcus gold is an agent that spreads easily and the behavior of the process is aggressive, with which this agent not only carries resistance to methicillin , but rather all ß-lactam antibiotics, including cephalosporins and carbapenem.
Answer:
D. Selective pressures by excessive antibiotic use have increased the frequency of resistant strains of S. aureus over the last few decades
