Answer:
Global warming is the change in the climate of the earth causing it to heat up whereas the greenhouse effect is a naturally occurring phenomena, constantly occurring due to the atmosphere and sunlight.
Widow's peak is a dominant trait (W). Tongue-rolling is a dominant trait (T). Two people who are heterozygous for both traits (widow's peak, tong-roller) get married and have children. Complete the Punnett square to show the parents the probabilities for each child, then answer the question that follows.
What is the probability that the parents will have a child without a widow's peak and unable to roll his tongue?
Group of answer choices
3/16
9/16
0/16
1/16
Answer:
The correct answers are -
A. 1) WWTt 2) WWTt 3)WwTt 4)wwTT
B. 1/16
Explanation:
We know that each gene have minimum two alleles or forms of the gene one is dominant and the other is recessive. So, it is given that W is dominant trait that represents widow's peak so the recessive allele would be w, similarly for the tongue-rolling trait dominant is T n recessive would be t.
So the dihybrid cross of heterozygous parents for both is shown in the punnet square given which lack few possibilities that can easily be carried out by the gametes mention there that are
1. WWTt by WT and Wt gamets
2. WWTt by WT and Wt
3)WwTt by Wt and wT
4)wwTT by wT and wT
And the possibility of a child without a widow's peak and unable to roll his tongue would be possible only if the alleles are recessive for the both trait which is one out of 16 in punnet square thus the possibility would be - 1/16

Most species of E. Coli are harmless or even helpful forms of bacteria that are found in the human intestine. E. Coli can aid humans in digestion and provide protection from other invading bacteria, but if the bacteria move to the human excretory system, they can replace other naturally occurring bacteria (Lactobaccilli). This can lead to bladder and kidney infections. Researchers found that by replenishing the excretory system with the naturally occurring bacteria, the infection caused by E. Coli is cured. Based on the research, what inference can researchers claim about the effect of bacteria?
Answer:
The inference is that bacteria can be pathogenic or characteristic of the commensal microbiota of different organs.
Explanation:
The human coexists with commensal micro-flora or commensal biota that are in balance and protect it from other pathogenic microorganisms, that is why we constantly live with a group of bacteria that do not generate pathological conditions in our body and even promote the stimulation of the immune response. .
When this balance is broken, pathogenic or opportunistic microorganisms invade, this is how they proliferate and generate infectious diseases that threaten the balance or state of human health.

60 POINTS!! PLEASE HELP!!When the level of blood testosterone has increased past its set point, a negative feedback signal will be sent to the hypothalamus.
Based on the diagram, what will be the result of this signal?
A) The hypothalamus will stop production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will increase and testosterone levels will decrease.
B)The hypothalamus will stop production of gonadotropin-releasing hormone. As a result, follicle-stimulating hormone will no longer be produced and testosterone levels will start to decrease.
C)The hypothalamus will stimulate production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will increase and testosterone levels will increase.
D)The hypothalamus will stimulate production of gonadotropin-releasing hormone. As a result, the production of follicle-stimulating hormone will be inhibited and testosterone levels will decrease.

A cell moves particles from a region of lesser concentration to a region of greater concentration by Facilitated Diffusion.
Facilitated Diffusion in the cell body is the passive movement of particles across a plasma membrane from a region of higher concentration to a region of lower concentration

HELP!! Which of the following is NOT true of protein structure?
A: Proteins' secondary structure is dictated by peptide bonds.
B: Proteins' tertiary structure is dictated by R group bonds.
C: Proteins have quaternary structure when they are arranged together.
The statement that is not true related to the protein structure is option b. Proteins' tertiary structure is dictated by R group bonds.
What is protein structure?It is classified as the three dimensional shape of the protein.
In the tertiary structure it does contain the single polypeptide chain that we called as the backbone or there more than one protein secondary structures
Also, it should not be dictated by R group bonds.
Therefore, we can conclude that the option b is correct.

Describe an example of fermentation that occurs in beneficial bacterial cells within animals and explain why it is important.
Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce. Fermentation helps break down nutrients in food, making them easier to digest than their unfermented counterparts. For example, lactose — the natural sugar in milk — is broken down during fermentation into simpler sugars — glucose and galactose ( 20 ).
Microbial fermentation takes place within the gastrointestinal tract of the majority of the animals by the bacterial cells, this helps in the process of digestion and in the synthesis of certain essential components like vitamins.
• The enzymatic decomposition and the usage of food components, mainly carbohydrates by the help of microbes like bacteria anaerobically is termed microbial fermentation.
• Within the gastrointestinal tract of the majority of animals, the process of fermentation takes place, however, the intensity of fermentation depends on the quantity of bacterial cells present, which is usually greatest in the intestine.
• The process of fermentation within the intestine by bacteria primarily helps in the process of metabolism and digestion of carbohydrates that does not get digested in the small intestine like residual starch and cellulose.
• Apart from this, microbial fermentation also helps in the production of vitamin K and some B vitamins.
Thus, microbial fermentation within the intestine of the majority of the animals performs essential functions like digestion and production of vitamins.

Answer:
If both are (PP and ww) and one is dominant the other is recessive then it is 100% purple.
IF both are heterozygous (pw) then it is 75% purple and 25% white
