The hominid that used skins and mats woven from leaves to collect fruit, berries, and seeds is the homo habilis. The homo habilis is a species of the tribe Hominini and one of the earliest members of the genus Homo. Homo habilis are also known as the "handy man" or "able man".
Answer:
c. Less oxygen consumption per second
Explanation:
- The sarcomere is a functional unit of muscle tissue. During repeated muscle contractions, the oxygen delivery to the muscle is reduced.
- As noted in the question, the rate and load of muscle contractions are the same under both conditions but the differences in the number of contractions in the second day experiment only increase.
- So as the number of contractions increases, more time is required to work. But continuous work can lead to a shortage of oxygen. Therefore, due to low availability, less oxygen per second is consumed. Lactic acid production by anaerobic respiration through muscle tissue causes muscle fatigue.
- Considering other dubious options, there is no increase in load and there is not much power generation. At the same time, ATP consumption increases due to continuous contraction, so the cellular ATP / ADP ratio is generally reduced.
- Since the calcium release by the sarcomere is reduced during continuous muscle contraction and the contraction rate does not change, the cross-bridge cycling speed is not affected.
Lipids are are inorganic compound that are poorly soluble in water, that consists of fat and oil. All lipids contain carbon, hydrogen, and oxygen. Some of them also contain nitrogen and phosphorus. The four main classes of lipids are fats, waxes, sterols, and phospholipids. The two parts make up lipids are glycerol and fatty acid.
The home land of homospecies is Africa, the continent. The first homospecies are believed to have been found in Ethiopia. Hope i helped.Have a nice day
I found the whole exercise with the options for it. Here are the options:
"A. mobility and protection of the DNA molecule during mitosis.
B. prevention of ligase enzyme action during replication.
C. Both answers regarding DNA mobility, protection and regulation in mitosis and transcription are correct.
D. regulation and protection of the DNA during transcription.
E. ensuring that sister chromatids will be attached prior to replication."
Correct answer: C.
Both A. and D. are correct reasons for what is the value in packaging DNA in tighter forms of chromatin. By having a more compact DNA it is easier to move it and protect each bit of it as it is being processed during mitosis, going from one side to the other, separating sister chromatids, etc. Also, by compacting and releasing DNA it is easier to regulate and protect DNA as it is being expressed - the parts that are being transcripted are not packed while those that are not being transcripted are packed.
