A secure food supply depends on all of the following EXCEPT?Choose one answer.
a. maintaing healthy soil and water
b. increased use of fertilizer
c. safe distribution of food
d. biodiversity

Answers

Let's  look at the options


a. maintaining healthy soil and water

This seems like an obvious option, since healthy soil is necessary to produce food. If a soil is not healthy, it will not have enough nutrients to produce plants. 
b.   increased use of fertilizer

Actually, the use of fertilizer is not necessary, as healthy soil will be enough to produce food. And increasing the use of fertilizer is even more not good, because it can be unhealthy and it can lead to the soil being infertile.

c. safe distribution of food

This is also very important. Imagine if you can produce healthy food, but you cannot deliver it safely to people and the food gets infected with bacteria on the way - then the whole effort is in vain!
d. biodiversity


This is actually very important, because if you have only one species, if this species is hit by a plague, you could loose all your crop! So you need to  keep a variety of crops

Answer: Line A is the enzyme, and Line B is the no enzyme

Explanation:

The reaction rate of a chemical reaction is greatly impacted by the presence of an enzyme. Enzymes are biological catalysts that speed up the chemical reaction by lowering the activation energy required for the reaction to occur. Without an enzyme, the reaction rate may be slow or even non-existent, whereas with an enzyme, the reaction rate can be significantly increased.

In order to compare the reaction rate with and without an enzyme, a graph can be plotted with time on the x-axis and the amount of product formed on the y-axis. The reaction without the enzyme would have a slower rate of product formation and would result in a lower slope on the graph. On the other hand, the reaction with the enzyme would have a sharper rate of product formation and would result in a steeper slope on the graph.

It is important to note that the reaction rate with an enzyme can only be increased up to a certain point, as the enzyme can become saturated with substrate molecules. At this point, the reaction rate will plateau and adding more substrate will not increase the rate of product formation.

Understanding the role of enzymes in chemical reactions is crucial in fields such as biochemistry and pharmacology, as many drugs and therapies work by targeting specific enzymes in the body. By manipulating the activity of enzymes, scientists can alter the rates of chemical reactions and ultimately impact physiological processes.

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. Think about the gametes this parent plant will produce. List the alleles in each gamete.

Answers

During gametes production, alleles randomly separate producing different combinations in daughter cells. The gametes in this example are YS, Ys, yS, ys.

How are gametes formed?

Gametes are formed during meiosis. Meiosis is a cell division process that produces gametes from germ cells. Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).

According to the segregation principle, alleles separate independently during gametes formation.

In anaphase I, homologous chromosomes separate, and each of them migrate to the opposite poles of the cell carrying one of the alleles. This random event leads to different chromosomal combinations in the daughter cells.

Now, let us analyze the problem,

Plant ⇒ heter0zyg0us for both seed shape and seed color ⇒ SsYy

  • S is the dominant allele and codes for spherical shape
  • s is teh recessive allele and codes for dented shape
  • Y is the dominant allele and codes for yellow
  • y is the recessive allele and codes for green

Gametes) YS, Ys, yS, ys.

So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.

Why has groundwater use increased?a.the total amount of freshwater has decreased
b.more of the available freshwater is stored in glaciers and icecaps
c.governments have banned the use of freshwater in rivers and springs
d.the demand for freshwater has increased due to population growth

Answers

Groundwater use has increased because D. the demand for freshwater has increased due to population growth. Obviously, the more people there are, the more water is going to be used, because all people in the world need water in order to survive. So they need to find ways to obtain more water, which is where groundwater comes into play.
