Answer:

The cytoplasm probably.

Explanation:

If there was cell membrane as an option, I would probably select cell membrane as the answer instead. The cell wall is fully permeable hence does not play a role in maintaining cell homeostasis, but rather plays a role in structural integrity of a plant cell. The mitochondria provides energy for cellular processes, not so much of maintaining cell homeostasis. The cytoplasm maintains a constant environment for cellular processes to take place hence would be the best answer out of all the three.

if the ratio of the ages of kisii and esinam is 3:5 and that of Esinam and Larry is 3:5 and the sum of the ages of all three is

larisa [96]

Answer:

The age difference between the oldest and the youngest is 48.

Explanation:

Given the following data;

The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.

The ratio of the ages of Esinam (E) and Larry (L) is 3:5.

The sum of the ages of all three is 147.

Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);

LCM of 3,5 = 15.

Hence, the ratio of the three ages is now;

K:E:L = 9:15:25

Let their ages be denoted by x;

$K:E:L = 9x:15x:25x$

The sum of all three ages is;

9x + 15x + 25x = 147

49x = 147

x = 147/49

x = 3.

To find the age difference between the oldest and the youngest;

The oldest is Esinam = 25x

The youngest is Kisii = 9x

Therefore, 25x - 9x = 16x

Substituting the value of x, we have;

x = 3; 16x = 16(3) = 48.

The age difference between the oldest and the youngest is 48.

Which part of the nervouds system consists of the brain and spinal cord:

Damm [24]

Answer:

c. CNS

Explanation:

The Central Nervous System (CNS) is responsible for receiving and transmitting information throughout the body. We can define it with the command center that coordinates the activities of the body. It consists of the brain and spinal cord, which are protected by the skull and spine respectively.

Both structures are reinforced by three connective blades, called meninges. They are: dura mater, arachnoid and pia mater. Between the last two there is a fluid that is responsible for the nutrition of the CNS and the minimization of possible trauma caused by mechanical shocks.

Which ligaments prevents the tibia from sliding forward in the knee joint?

Vladimir79 [104]

Answer: Anterior cruciate ligament

Explanation:The anterior cruciate ligament (ACL) connects the front of the tibia to the back of the femur. It keeps the tibia from sliding forward and limits its rotation. The posterior cruciate ligament (PCL) keeps the tibia from sliding backward. The patella ligament helps secure the patella over the front of the knee joint.
