Answer:
44
Explanation:
A somatic cell is diploid - it has 46 chromosomes. Half of these are from the mother, so there are 23 maternal chromosomes
A sex cell (gamete) is haploid - it has 23 chromosomes. There are (usually) two sex chromosomes in a diploid genome, either XX or XY, so there is one 1 in a haploid cell, giving a total of 22 autosomes
Barr bodies are inactive X chromosomes in a female somatic cell. This occurs to control dosage compensation (otherwise all the genes on the X in females would be expressed twice as much as they are in males). In a healthy female, there is normally one Barr body
A person with Kleinfelter's syndrome has two X chromosomes and one Y (XXY). They are biologically male, but have two X chromosomes. Therefore, one of these becomes a Barr body, as in females.
23 + 22 - 1 = 44
Answer:
1. When the number of calories a person consumes is equal to the number of calories he or she burns in a day, that person's body is in Energy Balance.
2. Someone who is in Positive Energy Balance eats more calories in a day than he or she bums.
3. Negative Energy Balance occurs when the number of calories a person bums in a day is greater than the amount he or she consumes.
4. Weight management involves applying strategies that allow someone to keep his or her body weight within a healthy.
5. The Basal metabolic rate is the amount of energy uses in order to perform its basic physiological functions.
6. The Thermic effect of food refers to the number of calories burned in order to digest absorb, metabolze, and store food.
7. The Lean body mass refers to his or her total body - fat mass.
Explanation:
This group of statements are related to body weight, the balance between the energy we consume through food and all the energy we burn through excercise and different activities, such as only mantaining our body temperature and normal processes.
Answer:
Macula densa cells, lower and renin.
Explanation:
Macula densa cells in the kidney detect lowers blood pressure which causes renin to be released from the juxtaglomerular cells which is an enzyme. The arterial cells observe the drop in blood pressure, and the decrease in Na concentration is transfer to them by the macula densa cells. The juxtaglomerular cells then release an enzyme called renin. Renin converts angiotensinogen which is a peptide, or amino acid derivative into angiotensin-1.
