commensalism:only one specie benefits why the other is neither helped not harmed. eg is the remora fish are very bony and have a dorsal fin that acts like a suction cup the remora fish gets a meal while the host gets nothing. selfish, sure but neither gets hurt

parasitism:one organism(the parasite)gains while the other(the host) suffers the deer thick is a parasite it attaches to a warm-blooded animal and feed on its blood. the thick benefits from the animal blood and unfortunately, the animal suffers from the loss of blood and nutrients and may get sick

Explanation:

A 78‐year‐old woman presents to clinic with her two daughters, who are concerned about her continued ability to live independently. She has thus far been highly self‐reliant and is opposed to the idea of leaving of her home of 30 years. The clinician performs a complete history and physical exam (including mental status and memory testing) as well as orders laboratory tests before providing the patient and her family the finding that she has age‐appropriate changes that do not reflect any particular disease process. Which of the following findings is most consistent with the normal aging process and does not impair the ability to live alone?
a) Decreased level of thyroid hormone
b) Mild cognitive impairment
c) Decreased adipose‐to‐muscle ratio
d) Age‐related cognitive decline
e) Persistent urinary incontinence

Answers

Answer:

d) Age‐related cognitive decline  

Explanation:

Age‐related cognitive decline is a natural condition associated with several symptoms including mild memory loss, mild forgetfulness, difficulty to remember names, etc. These symptoms are irregular but generally do not affect normal functions. Mild cognitive impairment is a condition related to memory loss that can lead to severe cases of Alzheimer's disease. Decreased level of thyroid hormone is a mild condition that can be diagnosed and properly treated, which is not related to aging. Persistent urinary incontinence is a mild disease that affects normal life but can also be easily diagnosed and treated. Finally, aging is associated with an increased adipose‐to‐muscle ratio (instead of a decreased rate).

Make a recommendation letter to Mayor or your Brgy. Chairman about the dangers brought by drug abuse in the community. Sight possible evidences of drug abuse like the presence of "hamog boys", "rugby boys", etc.​

Answers

Dear mayor.

I write this letter as a way to ask for measures for an evil that is plaguing our youth, drug abuse.

This abuse of drugs has been gradually increasing in our community and in other regions that are impacted by an insufficient economy and a flawed educational system, which has meant that young people find support only in the world of drugs.

The problem is that these substances are highly addictive, reaching the point where young people are unable to continue their lives, as they can only maintain their addiction. This opens the way for criminal and dangerous activities to be initiated, causing young people to lose their entire lives.

Therefore, I humbly ask that public policies be created to save our young people from this situation, in addition to regulatory policies for the use and sale of drugs. I believe that you will agree with the importance and urgency of this matter.

Thank you for your time.

Graciously.

M. Linn.

The recommendation letter will be written to show the disadvantages of drug abuse.

Dear Mayor,

I'm writing this letter to inform you about the dangers of drug abuse and its effect on society.

Drug abuse is the use of harmful drugs that has a negative effect on one's health. Drug abuse brings about bad behaviors and can initiate dangerous and criminal activities.

Also, it has a harmful effect on society. Therefore, it's vital for the government to address issues regarding drug abuse. An awareness program can be put in place to educate young ones about the dangers of drug abuse.

Yours sincerely,

John.

If talking regarding race, testicular cancer is more common in white men than in black men.

Some forms of recurring testicular cancer have a cure rate of more than 95%.

A

B
repetition
С
motivation
D
range of motion

Answers

Answer: the answer is D

The whole range of motion that a joint is capable of making, often its flexion and extension range. For instance, an injury may prevent a knee from fully extending 10 degrees. Thus, option D is correct.

What is the importance of range of motion in sports?

A component of sports science called range of motion (ROM) helps determine how far a certain joint can move.

Joint flexibility, as determined by the range of motion (ROM) of the specific structure, is crucial for both injury prevention and monitoring recovery after an injury.

Your body needs both range of motion and flexibility to function properly. Your body's joints are supported by bones, ligaments, muscles, and tendons, which allow each one to move within a certain range.

Therefore, range of motion s the best method to use when improving skills such as shooting a free throw, jumping rope, or serving a volleyball.

Use a punnett square to determine the possible genotypes of The offspring of a BB x bb cross
A genotypes
B phenotypes
C percent chance for each
Whoever answers will Mark brainlessness

Answers

Answer:

Answer in explanation

Explanation:

Since both parents only carry 1 type of allele ( dominant or recessive ), the offspring would have to be heterozygous according to the punnett square.

a) there is only 1 possible genotype : Bb there is a 100% chance for this

Because the dominant allele, in this case B, always shows in the phenotype, the phenotypic ratio would be 1:0. The recessive allele, b, only shows up if both parents pass along a recessive allele.

b) The offspring has a 100% chance of exhibiting trait B
