Why is it important for farmers to add nitrogen to their field of crops?
O Plants use nitrogen to make nucleic acids which provide energy.
O Plants use nitrogen to make carbohydrates which provide energy.
o Plants use nitrogen to make proteins which help them grow strong and healthy.
Plants use nitrogen to make lipids which help them grow strong and healthy.
Answer:
itrogen is one of the key nutrients that plants need to grow, and it is naturally available in limited quantities. Therefore, the addition of nitrogen fertilizer is an important component of achieving high agricultural yields.

What is the role of energy in living organisms? Is ti a mor or less important role than other characteristics of life?
Answer:
A huge number of chemical reactions take place continuously in a living cell. The whole of all chemical processes, that is, the total turnover of matter and energy is called metabolism.
Explanation:
All organisms need the energy to grow, reproduce, and respond to their surroundings. All these processes are achieved through metabolism that allows the energy available to them.

Which event in meiosis increases genetic variation within a population?
A. DNA condenses to form chromosomes.
B. Segments of chromosomes cross over.
C. Chromosomes duplicate themselves.
D. Chromosomes form pairs.
Answer:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occur during prophase 1
what are the steps in the digestion of protein
Explanation:
Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.

Answer:
the amount of carbon in the cycle can increase or decrease based on the number of factories present.
Explanation:
In the carbon cycle, carbon is exchange along many different forms on earth. Carbon is the main component of biological compounds, and it is released from organisms when they die or when fossil fuels are burned, hence, the diagram demonstrates this.

Answer:
rRNA - Ribosomal RNA, a molecular component of a ribosome, the cell's essential protein factory. Strictly speaking, ribosomal RNA (rRNA) does not make proteins. It makes polypeptides (assemblies of amino acids) that go to make up proteins
tRNA - Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.
Explanation:
Which depressive disorder features symptoms that are milder but longer lasting than the symptoms of the other depressive disorders?
Double depression
Major depressive disorder, single episode
Major depressive disorder, recurrent
Persistent depressive disorder
Answer:
Dysthymic disorder
Explanation:
The symptoms of dysthymia are similar to those of major depression but are less severe. However, in the case of dysthymia, symptoms last longer. A person has to have this milder depression for more than two years to be diagnosed with dysthymia.

Explanation:
Carnations with red, smooth petals are crossed with carnations with white, rough petals. In the F1, all the petals are pink and smooth. The F1 intercross yields the following F2:3/16 red, smooth6/16 pink, smooth3/16 white, smooth2/16 pink, rough
1/16 red, rough1/16 white, rougha) What are the parental genotypes?b) What are the F2 genotypes and phenotypes?c) What conclusions can be made about the allelic and gene interactions for both the petal color and texture alleles?
Answer:
a) What are the parental genotypes? RRSS and rrss
b) What are the F2 genotypes and phenotypes?
F2) 3/16 RRSS + RRSs (red, smooth)
6/16 RrSS + RrSs (pink, smooth)
3/16 rrSS + rrSs (white, smooth)
2/16 Rrss (pink, rough)
1/16 RRss (red, rough)
1/16 rrss (white, rough)
c) What conclusions can be made about the allelic and gene interactions for both the petal color and texture alleles? For petal color, it occurs incomplete dominance, being R the dominant allele for red and r the recessive allele for white, together expressing pink in heterozygosis. For texture, it occurs complete dominance of the allele codifying for smooth, S, over the allele codifying for rough, s.

A Logging removes trees from a hill, leaving a barren landscape.
Classification:
Explanation:
Answer:
Sediment pollution
Explanation:
There is no more vegetation on the hill to prevent sediment from being carried away
Logging removes trees from a hill, leaving a barren landscape is sediment pollution.
Pollution refers to any contamination of the natural environment with unwanted material or energy which renders the environment unfit for life. There are many kinds of pollution that affect various spheres of the environment such as land, air water etc.
When trees are logged from a hill in such a manner that the landscape is left barren, sediments can now easily be washed away by runoff into surrounding water bodies or other areas. This is an example of sediment pollution.

Which of the following correctly summarizes the development of the fetus during the second trimester?
Body functions, reflex development, and skin details
Cell division and tissue specialization
Gastrulation, neurulation, and rhythmic breathing
Specialization, function, and growth
Answer:
Body functions, reflex development, and skin details
Explanation:
The second trimester marks the period between the thirteenth to the twenty-sixth week. During this period of fetal development, the fetus begins reflex development such as sucking and swallowing. He is also now able to respond to stimuli.
Body functions are also developing at this stage. The baby can now kick, turn, and move his body. The brains are developing, the hairs and fingernails are also beginning to develop.
Skin details are also developed at this stage. For example, the vernix caseosa is produced to protect the skin of the fetus.

dy÷dx=(x-1)(x+3) at x=2
Answer:
[tex]\dfrac{dy}{dx}=\dfrac{4}{25}[/tex]
Explanation:
The given expression is :
[tex]y=\dfrac{(x-1)}{(x+3)}[/tex]
We need to find dy/dx at x = 2
[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(\dfrac{x-1}{x+3})\\\\=\dfrac{(x+3)\dfrac{d}{dx}(x-1)-(x-1)\dfrac{d}{dx}(x+3)}{(x+3)^2}\\\\=\dfrac{x+3-(x-1)}{(x+3)^2}\\\\=\dfrac{x+3-x+1}{(x+3)^2}\\\\\dfrac{dy}{dx}=\dfrac{4}{(x+3)^2}[/tex]
Put x = 2 in above expression
[tex]\dfrac{dy}{dx}|x=2=\dfrac{4}{(2+3)^2}\\\\=\dfrac{4}{25}[/tex]
Hence, the value at dy/dx is [tex]\dfrac{4}{25}[/tex]

Why the ureolytic bacteria produce CaCO3?
Answer:
Ureolytic bacteria hydrolyze urea to generate ATP by the efflux of ammonium ions through ATP-synthase, producing carbonate. In the presence of calcium ions in excess, calcium carbonate will precipitate.

OC) It resists temperature changes.
OD) it is cohesive.
O El It can be found as a solid. liquid. or gas.
Answer:
It is denser when frozen than when liquid.
