Help!!
Explanation:
ATP stands for Adenosine Triphosphate. It is the compound by which energy is stored and transferred in a cell.
It is made up of a nitrogenous base, the sugar and three phosphate groups.
The compound is produce as a product of photosynthesis and use to store energy.Energy is produced from this compound in the following steps,
a cell in need of energy spends the ATP currencyfrom the three phosphorous groups attached to the tail, one is split of.ATP then becomes ADP, Adenosine Di- phosphateit is the energy holding the phosphate group that is released and is used by the body.What organisms feed on dissolved organic matter?

Decomposers, which include bacteria, fungi, and other microorganisms, are the other major group in the food web. They feed on the remains of all aquatic organisms and in so doing break down or decay organic matter, returning it to an inorganic state.
[50 points... Will give brainliest] Explain how natural selection is impacted by genetic differences, variation, and survival.
Answer:
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

An Olympic sprinter has just broken the world record for the 100-meter dash. Which process will her body likely use to recover from her “oxygen debt”?
Answer:
Anaerobic respiration
Explanation:
In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.
The process through which the Olympic sprinter's body will likely use to recover from her “oxygen debt” is: an anaerobic respiration.
Anaerobic respiration can be defined as a chemical and biological process that involves the use of electron acceptor rather than oxygen to make energy (adenosine triphosphate) from carbohydrates (sugars).
Hence, an anaerobic respiration can take place or occur in the absence of oxygen.
On a related note, an anaerobic respiration is used to regain lost energy through the actions of electron acceptor when oxygen is lacking in the body.
In conclusion, the Olympic sprinter's body will likely use anaerobic respiration to recover from her “oxygen debt.”

Which animals should not be vaccinated?
Answer:
Every dog and cat should be appropriately immunised, and each individual animal should be vaccinated as frequently as considered necessary by their veterinarian to provide protection. The vaccination protocol to be followed and the vaccines to be used should be determined within a veterinarian–client–patient relationship. The decision should be determined by factors such as the individual animal’s health status, the animal’s age and likely effects of maternally derived antibodies (MDA), the particular disease and environmental risks to the animal, and the duration of immunity (DOI) of available vaccines.

Slowing signals between neurons is a function of __________. A. excitatory receptors B. excitatory neurotransmitters C. inhibitory receptors D. inhibitory neurotransmitters
Answer:
D
inhibitory neurotransmitters
Explanation:
Slowing signals between neurons is a function of inhibitory neurotransmitters. Neurotransmitters are the chemical messengers. Thus, the correct option is D.
What are inhibitory transmitters?Neurotransmitters are the chemical messengers in the body. These are released by the axon terminals of neuron and transmit the nerve impulse (message) to the neighboring cell (a muscle cell or a nerve cell).
There are primarily two types of neurotransmitters in the body, which are:
1. Excitatory neurotransmitter and 2. Inhibitory neurotransmitter
Inhibitory neurotransmitter have inhibitory effect on the neuron, they reduce the chances that a neuron will fire an action potential. They are responsible for slowing signals between neurons. Example: GABA (gamma amino butyric acid) is a common inhibitory neurotransmitter.
Therefore, the correct option is D.

A man who has cystic fibrosis married a healthy women. They produce 2 children who both have cystic fiber. What are the genotypes of the man and women? (use symbols to represent the alleles and which parent is which)
Answer:
The correct answer would be -
Father - both alleles are recessive for the gene - cc
Mother - carrier with the heterozygous condition - Cc
Explanation:
Cystic fibrosis is a recessive genetic disease that means it exhibits only if both copies of the gene mutated, If there is only one copy of the gene is mutated the person will be healthy however, he or she will be a carrier of the mutated gene.
Given: Father has cystic fibrosis which means he has two copies of the mutated gene - cc (c - recessive)
Female - she is healthy now there is two conditions possible
1. if the mother is healthy - CC (normal allele)
C C
c Cc Cc
c Cc Cc
All offspring are in the heterozygous condition that means they are healthy carriers which is not given in the question so women must be a carrier
2. Carrier mother - Cc
C c
c Cc cc
c Cc cc
Here 50% chances of having children with CF so it is possible as two offsprings have CF according to question
Thus, Father - both alleles are recessive for the gene - cc
Mother - carrier with the heterozygous condition - Cc

Jacob a 40 year old man who is 6 foot tall and weighs 225 pounds has been diagnosed with atherosclerosis. What healthcare plan would you design for this patient? prescribe a medication to reduce bad cholesterol and no other changes need to be made. patient is just slightly overweight and she is worrying to much about his health, therefore no change. patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds prescribe a medication that lowers blood pressure and no other changes need to be made.
Answer:
The patient should make lifestyle changes to healthier foods and start an exercise plan to reduce his weight by 30 pounds.
Explanation:
We know that the patient weighs 225 pounds, and his height is 6 feet. With this information, we can determine his Body Mass Index (BMI) using the formula:
BMI= weight/(height)²
BMI= 225/(6)²
BMI= 30.5
Once that we calculated his BMI, we compare the result with the reference chart, here we can see that for his height. he is obese. This coincides with the fact that he has been diagnosed with atherosclerosis. His body has been placing the extra fat in the arteries.
The best plan for Jabob would be to make a lifestyle change to healthier foods and an exercise plan that helps him to lose weight so that his BMI would be approximately 25 and his weight of 195 pounds. Also, this plan will reduce cholesterol levels.

Choose the term that best matches the description given. Treatments that destroy or decrease the growth of a microbe infection in a patient ______ a. Disinfects b. Antiseptics c. Sterilization d. Antimicrobials e. Quarantine
Answer: The correct option is D (Antimicrobials).
Explanation:
Antimicrobial treatment is defined as therapies that are given to patients to either inhibit or kill the growth of microorganisms IN their body cells. The antimicrobial treatment can be grouped into two based on their mechanism of action. These includes:
--> Microbiocidal therapy: This type of treatment when given, kills the microorganisms in the cells of the patient.
--> Microbiostatic therapy: This type of treatment aims at inhibiting the growth of microorganisms when administered to a patient.
The antimicrobial drugs achieve their role usually through their different modes of action which includes:
--> cell wall inhibition
--> inhibition of cell membrane function
--> protein and nucleic acid synthesis inhibition.
Disinfects, antiseptic and sterilisation are all different ways of eliminating microorganisms but not used as invitro (within) treatment for patients. Therefore the term that best matches the description given is antimicrobials.
