Answer:
The total amount of energy transferred during photosynthesis for this ecosystem equals 260,000 kcal/m2/yr.
Explanation:
To answer this question, we need to know that
gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesisnet primary productivity (NPP) = difference between GPP and respiration rateSo, to calculate GPP we need to sum NPP to Respiration rate. This if,
NPP = 165,000 kcal/m2/yr
R = 95,000 kcal/m2/yr
NPP = GPP – Respiration
Then,
GPP = NPP + R
GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr
GPP = 260,000 kcal/m2/yr

Answer:
plant cell can make its own glucose; an animal cell cannot
Explanation:
Chloroplasts are found in plant cells, but not in animal cells. The purpose of the chloroplast is to make glucose that feed the cell's machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating glucose.

B.
Chromosomes are threadlike structures that carry genetic information.
C.
Humans receive the majority of their chromosomes from their mother.
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. Humans receive one set of 23 chromosomes from their mother and the other set from their father.Chromosomes are arranged in 23 distinct pairs in the human body.Hence, option b) is the correct option.

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

The opossum, which is native to North America, and the kangaroo, which is native to Australia, are marsupials.
The fact that both these mammals incubate their immature offspring in a pouch provides evidence that they -
O are descended from a common ancestor
O belong to the same species
O must range great distances to eat
have very similar skeletal structures
Answer:
Belong to the same species
Explanation:
Marsupials carry their young in "pouches", and are therefore related to other marsupials, like the kangaroo, opossum, wombats, and koala to name a few.
The opossum is a native of North America as the kangaroo is a native to Australia and both of them are mammals thus boh belong to the same specie. Thus option B is correct.
What are mammals?A mammal is an animal that is warm-blooded and has hair, vertebrates, and backbone. These creatures share human relations and produce milk for their young ones. The kangaroo is like an opossum that is marsupials carry their young in "pouches".

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.

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.

A mutation that could be inherited by offspring would result from-?
Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.
Explanation:
A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.
What is mutation?Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.
As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.
Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.
Thus, the correct option is D.
