Besides the HCT, what other component of blood could be measured to give a better understanding of oxygen-carrying capacity? Exp
tresset_1 [31]

Answer:

The haemoglobin levels or counts can be used.

Explanation:

The oxygen carrying pigment of the blood is the heamoglobin (Hb).it is a protein molecule with for heam groups,Each of the latter can bind with  4 molecules of oxygen in a cooperate bonding.The more oxygen molecules binding by Hb,the more oxygen is carry in RBC.

Therefore if the number of Hb counts is reduced in an individual the volume of oxygen in the RBC of the subject should  reduced,Therefore, this should be a good indicator of the lower oxygen capacity of the blood of the individual.

Basically in a physiological female the Hb count/100ml of blood is 12-16g/ml,like wise 13-18g/100mI in a physiological  man.

Therefore fluctuations in the levels of these values below the set points  is an indicator of distortion in the oxygen carrying capacity of the blood.

The  amount of the blood in volume that contains RBC is called Hematocrit. Therefore for accuracy the HCT together with the Hb counts are good indicators of oxygen capacity of the blood.

How wpukd you know if two chromosomes were homologous
nadya68 [22]
Homologues are chromosome pairs of the same length, centromere position, and staining pattern with genes for the same characteristics at corresponding locations. One homologous chromosome is inherited from the organism's mother, the other from the organism's father during sexual reproduction. The crossing over, or synapse, occurs during meiosis, which is the process of gamete formation.

Which end of actin filaments within sarcomeres is associated with (attached to) Z discs?a) The plus end for all actin filamentsb
aliina [53]

Answer:

The plus end for all actin filaments.(Ans. A)

Explanation:

All three types of muscles (cardiac, smooth, and skeletal) utilize actin filaments to generate force which leads to cell contraction. Actin filaments is organized into sarcomeres which function as the fundamental unit of contraction.

Sarcomeres are approx 2.4 micro meter in length, and they are bounded at both end with the help of Z-disks. Plus end of the Z-disks are oriented with actin filaments and their minus ends to the direction of center of the sarcomeres. Z-disk consist an actin capping protein, which is known as cap-Z. Cap-Z helps to bind plus end of the actin filaments.
