Answer:

1. 39 J; 2. 3.9 % usable; 3. 96.1 % unusable

Step-by-step explanation:

1. Available energy

Energy consumed              = 1000 J

Less waste         = - 177 J

Less respiration = <u>-784 J </u>

Total energy lost                = <u>-961 J </u>

Available energy                =   39 J

2. Percent of total energy usable

The chipmunk could use only 39 J of the original 1000 J.

% of energy usable = 39 J/1000 J × 100 % = 3.9 %

3. Percent of energy unusable

The chipmunk lost 961 J of the original 1000 J.

% of energy unusable = 961 J/1000 J × 100 % = 96.1 %

Humans and apes have five fingers they can use to grasp objects. Do you think these are analogous or homologous structures
Ann [662]
Human and apes have 5 fingers that are used for grasping objects, so they have the same function, but they also have a common ancestor and are closely related, that means that this is an example of homologous structures. In evolutionary biology, the term homologous structures means that there are organs and skeletal elements of animals and organisms, that by virtue of their similarity, suggest their connection to a common ancestor.

"if left untreated, hypertension can lead to ____."
katrin2010 [14]

If left untreated, the probable lead for hypertension to an individual is kidney failure. It is because the blood pressure is associated with the kidneys because the nephrons of the kidneys are being supplied with the blood vessels dense network and also because of the blood that flows through it, when there is a presence of hypertension and left untreated, it could cause the kidney to weaken or harden—causing kidney failure.

DHEA is a hormone involved in muscle growth, bone density, and the functioning of the cardiovascular system. DHEA production inc
sertanlavr [38]

Answer:

5%

Explanation:

The adrenal cortex in both males and females produce a small amount of weak androgens. One of the major weak androgen secreted by adrenal cortex is dehydroepiandrosterone (DHEA).

Levels of dehydroepiandrosterone secretion exhibit changes with age. The dehydroepiandrosterone secretion increases till the age of 20-24 years and falls off with increasing age after the age of 30 years in both males and females. The DHEA production at the age of 80 years is about 5% of its secretion at the age of 30 years.

Would a muscle cell be able to produce a functional contraction if it lacked t-tubules?
hjlf

The answer would be no. T-Tubules or Transverse tubules are additions of the sarcolemma that infiltrate into the center of cardiac and skeletal muscle cells. There would be no functional contraction since it would not be capable to communicate or interconnect with the other cells.
