What is the ecosystem?

An ecosystem is a set formed by the interactions between biotic components, such as living organisms: plants, animals and microbes, and abiotic components, chemical and physical elements, such as air, water, soil and minerals.

Broad categories of terrestrial ecosystems are called biomes. In ecosystems, matter and energy are conserved.

Can someone describe these:
Menstrual Phase
Follicular Phase
and Luteal phase

Thanks!!!

Answers

Answer:

(menstrual phase) this is the phase where the unfertilized ovum and endometrium that was formed in readiness for implantation slough off or come out due to a sudden drop in progesterone levels

(follicular phase) this is where the graafian follicle in the ovary develops. from primary follicles due to secretion of follicle stimulating hormone by the pituitary gland and matures there after due LH hormone which will also stimulate the ovary to release the ovum

(luteal phase)this is the phase after the ovum has been released where the remains of the ruptured graafian follicle undergo reorganization to form a corpus luteum/yellow body which now produces progesterone which causes thickening of endometrium in readiness for implantation

hope this helps

Answer:

The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. 2) The follicular phase is a phase of the estrous cycle during which follicles in the ovary nature from primary to a fully mature grafian follicle.It ends with ovulation.3) The luteal phase begins during the second half of a menstrual cycle normally lasting around 12 14 days after the ovulation and it is responsible for producing progesterone.

Suppose you take glycine tRNA and modify it so that the glycine is changed to valine. You then find that the amino acid sequence in the generated proteins does not show the expected change. This result would suggest that the protein synthesis machinery recognizes the _______ and is _______ with what was actually found by researchers.

Answers

Answer:

Suppose you take glycine tRNA and modify it so that the glycine is changed to valine. You then find that the amino acid sequence in the generated proteins does not show the expected change. This result would suggest that the protein synthesis machinery recognizes the tRNA anticodon and is congruent with what was actually found by researchers.

Explanation:

A group of researchers led by Seymour Benzer demonstrated that the anticodon of the charged tRNA was recognized by the protein synthesis machinery, when they changed the amino acid sequence. This example shows the exact result as found by the researchers.

Answers

Answer:

The goal of disinfection of public water supplies is the elimination of the pathogens that are responsible for waterborne diseases. The transmission of diseases such as typhoid and paratyphoid fevers, cholera, salmonellosis, and shigellosis can be controlled with treatments that substantially reduce the total number of viable microorganisms in the water.

While the concentration of organisms in drinking water after effective disinfection may be exceedingly small, sterilization (i.e., killing all the microbes present) is not attempted. Sterilization is not only impractical, it cannot be maintained in the distribution system. Assessment of the reduction in microbes that is sufficient to protect against the transmission of pathogens in water is discussed below.

Chlorination is the most widely used method for disinfecting water supplies in the United States. The near universal adoption of this method can be attributed to its convenience and to its highly satisfactory performance as a disinfectant, which has been established by decades of use. It has been so successful that freedom from epidemics of waterborne diseases is now virtually taken for granted. As stated in Drinking Water and Health (National Academy of Sciences, 1977), "chlorination is the standard of disinfection against which others are compared."

However, the discovery that chlorination can result in the formation of trihalomethanes (THM's) and other halogenated hydrocarbons has prompted the reexamination of available disinfection methodology to determine alternative agents or procedures (Morris, 1975).

The method of choice for disinfecting water for human consumption depends on a variety of factors (Symons et al., 1977). These include:

its efficacy against waterborne pathogens (bacteria, viruses, protozoa, and helminths);

the accuracy with which the process can be monitored and controlled;

its ability to produce a residual that provides an added measure of protection against possible posttreatment contamination resulting from faults in the distribution system;

the aesthetic quality of the treated water; and

the availability of the technology for the adoption of the method on the scale that is required for public water supplies.

Economic factors will also play a part in the final decision; however, this study is confined to a discussion of the five factors listed above as they apply to various disinfectants.

The propensity of various disinfection methods to produce by-products having effects on health (other than those relating to the control of infectious diseases) and the possibility of eliminating or avoiding these undesirable by-products are also important factors to be weighed when making the final decisions about overall suitability of methods to disinfect drinking water. The subcommittee has not attempted to deal with these problems since the chemistry of disinfectants in water and the toxicology of expected by-products have been studied by other subcommittees of the Safe Drinking Water Committee, whose reports appear in Chapter III of this volume (Chemistry) and Chapter IV (Toxicity) of Drinking Water and Health, Vol. 3.

Organization of the Study

The general considerations noted in the immediately following material should be borne in mind when considering each method of disinfection. Available information on the obvious major candidates for drinking water disinfection—chlorine, ozone, chlorine dioxide, iodine, and bromine—is then evaluated for each method individually in the following sections. Other less obvious possibilities are also examined to see if they have been overlooked unjustly in previous studies or if it might be profitable to conduct further experimentation on them. Disinfection by chloramines is dealt with in parallel with that effected by chlorine because of the close relationship the former has to chlorine disinfection under conditions that might normally be encountered in drinking water treatment.

Proteins in the cell membrane have many functions. Which type of protein would be used for cell recognition and as a receptor? A. Pore proteins B. Endoplasmic proteins C. Glycoproteins D. Integral proteins

Answers

Answer:

C. glycoproteins

Explanation:

Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.

A garden has a length of 1.5 x102 m and a width of 0.5 x 102 m. what is the area of the garden?

Answers

Answer:

7.5 × 10^3 m^2

Explanation:

The garden described in this question takes the shape of a rectangle, which has a length of 1.5 x102 m and width/breadth of 0.5 x 102 m.

To calculate the area, we use the formula for calculating the area of a rectangle, which is;

Area = length (L) × width (w)

Area = 1.5 x102 m × 0.5 x 102 m

Area = 150 × 50

Area = 7500

This, the area of the garden is 7500m^2 or 7.5 × 10^3 m^2

A mutation in human ATPase 6, which corresponds to E. coli subunit a, from leucine to arginine at position 156 may allow the movement of protons across the membrane, but not the rotation of the ring of c subunits. How might this possible mechanism affect the function of ATP synthase

Answers

Answer:

H+ protons will not be delivered from the cytoplasm towards the extracellular side of the cell membrane

Explanation:

ATP synthases are enzymes that catalyze the hydrolysis of phosphate bonds in the adenosine triphosphate (ATP) or the formation of ATP from adenosine diphosphate (ADP) and phosphate. The hydrolysis of ATP produces the rotation of a ring composed of six or more structurally different ATPase C subunits. The rotation of this ring enables the delivery of H+ protons towards the extracellular membrane surface and this gradient is used to generate energy by producing ATP. In consequence, when the ATPase ring can not move, H+ will accumulate in the cytoplasm, the proton gradient through the membrane will not occur, and ATP will not be produced.

Explanation:

What process is similar in function to genetic engineering but different in the mechanism it uses? A. Replication in a bioreactor B. Cellular Respiration C. Breeding for specific traits D. Genetic Calculus

Answers

Option C. Breeding for specific traits is a similar process in function to genetic engineering but different in the mechanism it uses.

Genetic engineering refers to the process of using recombinant DNA methodologies to alter the genome of a particular organism and thus obtain the desired characteristics/traits in organisms derived from them.

An example of genetic engineering is the use of recombinant DNA methodologies to develop Escherichia coli strains that generate human insulin.

Moreover, selective breeding refers to the process aimed at developing organisms with desirable characteristics by choosing parents with these traits in order to cross them and produce offspring with these phenotypic traits.

For example, wheat plants with better yields can be obtained by crossing between wheat varieties that exhibit desired phenotypic traits.

In conclusion, Option C. Breeding for specific traits has a similar objective that genetic engineering but the mechanism to reach this objective is different.
