After a month of heavy rain, a formerly clear pond on a golf course is covered with slimy green algae. What do you think happened?

Answers

Pond water most definitely gets cloudy after a good rain, most of this cloudy water caused by dust, pollen, dirt, debris, and other materials getting washed into the pond and as this material floats and circulates in the pond it gives a cloudy look to the pond, and typically it is just a matter of a day or so for the pond water to be filtered clear again. After your pond water has filtered clean, it is a good time to clean your pond filter too, as all those materials need now to be removed from your pond filtration system.

However, sometimes pond green water conditions can occur. The green water condition in the pond occurs because of the sudden introduction of nitrate and nutrient rich water into your pond; the nutrient levels spike, the planktonic algae in your pond has a sudden huge food (nutrient) supply available, so it can now reproduce like mad increasing in numbers exponentially and wah-lah! You’ve got green water, and green water is simply that….large numbers of floating planktonic algae that now are so densely populated that their green coloration from chlorophyll makes your water appear green.

Provide an example of how your body could maintain homeostasis in response to detecting that the body temperature was falling below 98.5 degrees.


Answers

Answer:

Our body produces heat energy.

Explanation:

When our body temperature decreases than normal range, our body produces heat to maintain internal heat in the normal range. Our internal body temperature is regulated by hypothalamus which is a part of our brain. The hypothalamus regulate the temperature and take actions to maintain it in the normal range of temperature which is about 37°C. If our body temperature is too low, the hypothalamus order to the body to generates heat energy and maintains heat in the normal range. The sweat glands remain inactive in order to prevent heat losses.

if there is 8 g of a substance before a physical change, how much will there be afferwards

Answers

Answer:

The correct answer is 8 g.

Explanation:

During a physical change, the identity of the substance does not change, because no chemical reaction occurs. So, after the change, the amount of substance is still the same. Examples of physical changes are changes in the state of matter (solid-liquid-gas). If 8 grams of ice (water in the solid-state) are melted, after the melting process we will have 8 grams of water in the liquid-state, but still 8 grams of water.

Which statement best explains how respiration and photosynthesis are related to one another?

C. Photosynthesis gives off carbon dioxide that is required for respiration
D. Respiration gives off carbon dioxide that is required for photosynthesis

Answers

Answer: D

Explanation:

photosynthesis - takes in water, energy from the sun, and carbon dioxide and releases oxygen and glucose (sugar)

Archaebacteria and eubacteria are classified into different kingdoms, but at one time they were both classified in the Kingdom Monera. Which statement best describes why the classification of these organisms was changed?

A. The kingdom became too large and had to be made into two smaller kingdoms.
B. New biochemical data showed different evolutionary relationships within the kingdom
C. The archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.
D. Chromosomal analyses indicated a new genetic combination had arisen within a certain organisms in the kingdom.

Answers

Answer:

I think the option C is correct

The statement best describes the classification of these organisms was changed is the archeabacteria and eubacteria habitats were too different to be classified in the same kingdom.

What are the characteristics of Archaebacteria?

Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.

Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences.

The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.

During translation, tRNA adds the correct amino acid to the growing protein, following the mRNA codon sequence. Tryptophan, Lysine, Leucine, Tyrosine.

What is translation?

Translation is the stage in protein synthesis that follows transcription, and occurs in the cytoplasm.

When mRNA leaves the nucleus and moves to the cytoplasm, it meets a free ribosome that is the primary structure for protein synthesis. Ribosomes are composed of two subunits of rRNA associated with different tRNA that carries amino acids.

The ribosome reads mRNA in the 5' to 3' direction, and, according to the codons that are being readen in mRNA, tRNA transfers the correct amino acids to build the polypeptide chain.

Let us remember that the codon is the sequence of three nucleotides present in mRNA. The molecule carriesa a start codon and stop codons.

Each tRNA has two important sites. One of them is the antidocon that couples with the codon of the mRNA molecule. The other site couples with the coded amino acid.

The protein is synthesized from the amino terminus to the carboxy terminus.

In the example,

DNA              mRNA             tRNA             Amino Acid

ACC               UGG                ACC             Tryptophan

TTC                AAG                UUC             Lysine

GAT               CUA                 GAU             Leucine

ATA                UAU                AUA              Tyrosine

In a eukaryotic cell, which of the following processes directly involves DNA?

Answers

The provided question lacks the options, however, the options associated with the question is as follows;

A. translation

B. cellular respiration

C. active transport of ions

D. replication of chromosomes

Answer:

The correct answer is - D. replication of chromosomes.

Explanation:

During every cell division, either meiosis or mitotic the chromosomal DNA present in the nucleus is needed to be duplicated and the process that involves the duplication of this chromosomal DNA is known as replication of chromosome which takes place during the interphase of the cell division.

All other processes mentioned in the options are not involved or directly not involved in the processes. Translation involves the mRNA in the cytoplasm to produce amino acids with the help of ribosomes. Cellular respiration involves mitochondria and does not require DNA in the process.

At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.
