Describe the function of Chloropasts

One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, spec

Arte-miy333 [17]

Answer and Explanation:

<em>Biodiversity </em>composes of different species living in a certain restricted area. It is the variability of living beings in a natural environment, involving all the species on the planet and their genetic material. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species form.

Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.

Biodiversity, in equilibrium with abiotic factors, provides ecosystem services, which are important for the maintenance of all forms of life, including human beings.

<em>Ecosystem services</em>

When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:

Provision or supply:

These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.

Regulation:

Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.

Cultural:

Refers to not the material benefits. Ecosystems provide a recreational place or area to spend time and learn. They provide a spiritual/religious space, are a source of inspiration. Ecosystems are cultural patrimony and the source of scientific knowledge.

Why does organic plant remains best describes coal?

xz_007 [3.2K]

Coals are the most abundant organic-rich sedimentary rock. They consist of undecayed organic matter that either accumulated in place or was transported from elsewhere to the depositional site. The most important organic component in coal is humus. Is correct

Kruka [31]

Answer: Yes, the samples of R and X of α-actinin-3 (ACTN3) R577X polymorphism provided evidence that the two options are not equally likely Conduct the test using a test for a proportion, using where represents the proportion of the population classified R.

Explanation: On one hand, from the reports of the following researcher; (North et al., 1999), (Gomez-Gallego et al., 2009; Yang et al., 2003), (Vincent et al., 2007) and (Kikuchi et al., 2014) supported that α-actinin-3 (ACTN3) R577X polymorphism is associated with muscle fibre type for power, elite performance, important for anchoring actin and plays a regulatory role in coordinating muscle fibre contractions.

On the other hand, researchers such as Erskine et al. (2014), on 51 untrained healthy Caucasian males, Delmonico et al. (2007) studied an association between the ACTN3 genotype and training responses in a large Caucasian population of 157 relatively healthy sedentary Caucasian men and women, Gentil et al. (2011) detailed the outcomes of 141 young men, Pereira et al. (2013) reported the influence of ACTN3 polymorphisms and ACE I/D alone and in combination with muscle strength, power, and functional phenotype in older Caucasian women following 12 weeks of high-speed power training and Lima et al. (2011), conducted a study of 246 women (age 66.7 ± 5.5 years) agreed that in healthy relatively young sedentary Caucasians that both the ACE I/D and ACTN3 R577X polymorphisms (alone or in combination) were found to be associated in the baseline muscle strength, muscle strength resistance training, thickness of muscles and athletic status.

However, the X allele, which is associated with the absence of ACTN3 protein, is suggested to impair the performance of high force/speedy muscle contractions. Using (Gentil et al., 2011) as the control experiment, the sample of 141 men performed two resistance training sessions per week for 11 weeks. The Participants were tested for 1-repetition maximum (1RM) bench press, knee extensors peak torque and knee extensors muscle thickness at baseline and after the training period. Consequently, genotype distribution was 34.4% for RR, 47% for RX, and 18.6% for the XX genotype. Drawing an inference from the to the results, the R577X polymorphism at ACTN3 was not associated with baseline muscle strength or the muscle strength response to resistance training. However, only carriers of the R allele showed increases in muscle thickness in response to training.

Exceptions: (Clerkson et al, 2005) posited that women with RR genotype had a greater increase in muscle power than the men while in Delmonico et al (2007) disputed that claim by saying that women with XX genotype have greater relative responses than men.
