Mr. A.H., age 44, had a generalized tonic-clonic seizure unexpectedly at work_ He had no history of seizures, trauma, infection,

NemiM [27]

Answer:

a tumor is a growth of abnormal cells in the brain tissue, in this case they are malignant cancer cells since their growth is very fast, some are primary that start directly in the brain and other metastatic that start in another part of the body, in the case of Mister AH always had primary symptoms.

Tumors in the brain can show various symptoms. These are some of the most common:

Headaches, usually in the morning

Nausea and vomiting

Changes in the ability to speak, hear or see

Balance or walking problems

Problems with thinking or memory

Weakness or longing to sleep

Changes in mood or behavior

Seizures

tumors can destroy brain cells which can cause inflammation and damage to parts of the body depending on where in the brain this is exerted, this also aggravates the symptoms.

Radiation therapy used to treat brain cancers increases the risk of brain tumors up to 20 to 30 years later.

In this case, he was causing this same reaction to Mr. AH, which may also have another type of tumor such as

Meningiomas and schwanomas are two other types of brain tumor. These tumors:

They occur in most cases between the ages of 40 and 70.

They are not usually cancerous, but they can still cause serious complications and death due to their size or location. Some are cancerous and aggressive.

Differentiate between proximate and causations of a behavior

postnew [5]

Answer:

The ultimate level of causation refers to the behavior’s evolutionary significance; how the behavior enhances reproductive fitness. The proximate cause refers to the immediate cause of a behavior, whether that be hormonal, neurological, cognitive, interpersonal, or cultural. For example, the proximate cause of humans eating more cookies, cake, and ice cream involves the psychological tendency to desire and enjoy foods with high sugar and fat content. The ultimate cause involves the high caloric content of both sweet and high fat foods, which promotes physical survival in resource-scarce environments.

7. Wha

jasenka [17]

Answer:

The correct answers are :

a) syndrome Could be autosomal recessive or dominant

b) If it is autosomal recessive - no ,

and if it is autosomal dominant - yes, (II-4) - Aa

c) probability of the another child :

Autosomal recessive: Aa x aa 50%

Autosomal dominant: aa x Aa 50%

Explanation:

a) Marfan syndrome could be inherited by the autosomal recessive or dominant pattern on the basis of following characters according the pedigree gives:

- transmitted by anyone regardless of sex male or female

- characters should not skip generations

- A cross between affected person and an normal person should produce approximately half of the affected offspring.

b) Assuming that autosomal dominant than there is two possibilities :

1) in case of I 2 genotype is heterozygous which means it is Aa which will produce Aa Aa aa and aa with crossing with aa as per pedigree however it is incorrect according the offspring given in II.

2) If I 2 is AA- then offspring will be Aa, Aa, Aa and Aa. which is correct according the pedigree.

thus, the answer is - Aa

c) the punnet square as per question is :

II2 - Aa × II1 - aa

A a

a Aa aa

similar with autosomal recessive

thus, the correct answer is 2 out of 4 that is 50%
