We use heat and additional bacteria to make a cheesefrom yoghurt.
Do you think the heat can kill the bacteria ?
If you say Yes why we need to use bacteria?
If you say No why not the bacteria can kill us when we feed it?
bacteria are rapidly killed at temperatures above 149°F (65°C). we need to use bacteria because We could not survive without all the bacteria living on and inside us. They act as part of our immune systems, digest foods such as dairy that we cannot break down ourselves and provide us with nutrients and minerals that we need to survive.

Trace the path of nitrogen from atmospheric N2 into glutamate. Name the enzymes, substrates, products, and coenzymes.
Answer:
The path of the atmospheric nitrogen to the glutamate involves three broad steps where it is fixed to ammonia which is incorporated into glutamine and then finally forms glutamate by catalyzation reaction. These three reactions are given below with products formed, reactants, and enzymes involved:
1. Atmospheric nitrogen is the reactant that is reduced to ammonia (product) in this reaction. This reaction is catalyzed by the nitrogenase complex present in bacteria present in legumes:
N2 + 10H+ + 8e- + 16ATP → 2NH4+ + 16ADP + 16Pi + H2.
2. Ammonia (reactant) is incorporated into glutamine (product) in this second reaction which involves glutamine synthetase as catalyst: Glutamate + NH4+ + ATP → glutamine + ADP + Pi + H+.
3. Finally glutamine (final product) is formed by the glutamine (substrate) catalyzed by the glutamate synthase
α-Ketoglutarate + glutamine + NADPH + H+ → 2 glutamate + NADP+.
Solution :
Firstly the nitrogen molecule, [tex]$N_2 $[/tex] is reduced to to [tex]$NH_3$[/tex] (ammonia) in the reaction that is catalyzed by nitrogenase complex. It is present in the certain prokaryotes, which includes some of the live symbiotically with the legumes
[tex]$N_2 + 10H^ + + 8e^- + 14 \ ATP \rightarrow 2NH_4^+ + 16ADP + 16Pi + H_2$[/tex]
The ammonia is then incorporated into the glutamine in reaction that is catalyzed by the glutamine synthetase:
[tex]$\text{glutamate} + NH_4^+ + ATP \rightarrow \text{ glutamine} \ + ADP + Pi + H^+$[/tex]
And finally the glutamate synthase that catalyzes the formation of the glutamate from the glutamine :
α-Ketoglutarate + glutamine + NADPH + [tex]$H^+ \rightarrow 2 \ glutamate + NADP^+ $[/tex]
Also there is an alternative minor route for the formation of glutamate from ammonia that involves reaction catalyzed bu the glutamate dehydrogenase :
[tex]$\alpha - \text{Ketoglutarate} + NH_4^+ + NADPH \rightarrow \text{ glutamate} \ NADP^+ + H_2O $[/tex]

Which of the following is a result of the exchange of homologous chromosome parts during the process of meiosis?
a offspring with unique combinations of traits
b decreased gamete number
c random mutations
d decreased number of alleles on each chromosome
Answer:
a offspring with unique combinations of traits
Explanation:
This question is describing a process called CROSSING OVER, which is unique to meiosis. Crossing-over is a process whereby non-sister chromatids of a homologous chromosome exchanges a segment or portion of their chromosome. This process of crossing over occurs in the PROPHASE I stage of meiosis.
The result of crossing-over, if it occurs, is to promote genetic diversity among the species of an organism. This is because the exchange of chromosome segments produces an offspring with a unique combinations of traits. Alleles of a gene are recombined in such a way that a unique combination is produced via the process.

Answer:
As soon as the concentration passed 39, the plants died. Adding to that, I have also found out that the lower the concentration of the sugar, the more the average height becomes.
Explanation:
Plant growth and development are tightly controlled in response to environmental conditions that influence the availability of photosynthetic carbon in the form of sucrose. Trehalose-6-phosphate (T6P), the precursor of trehalas in the biosynthetic pathway, is an important signalling metabolite that is involved in the regulation of plant growth and development in response to carbon availability. In addition to the plant’s own pathway for trehalas synthesis, formation of T6P or trehalas by pathogens can result in the reprogramming of plant metabolism and development. Developmental processes that are regulated by T6P range from embryo development to leaf senescence. Some of these processes are regulated in interaction with phytohormones, such as auxin. A key interacting factor of T6P signalling in response to the environment is the protein kinase sucrose non-fermenting related kinase-1 (SnRK1), whose catalytic activity is inhibited by T6P. SnRK1 is most likely involved in the adjustment of metabolism and growth in response to starvation. The transcription factor bZIP11 has recently been identified as a new player in the T6P/SnRK1 regulatory pathway. By inhibiting SnRK1, T6P promotes biosynthetic reactions. This regulation has important consequences for crop production, for example, in the developing wheat grain and during the growth of potato tubers.

The law of_____
is the law describing how factors
for the same trait go to different gametes.
The answers or on the photo
Answer:
The correct answer is - segregation.
Explanation:
The law of segregation states that out of two factors or alleles of a gene located in an organism, only one allele or factor is distributed to each sperm cell or egg cell (gamete) randomly, So, the segregation of the alleles are random and only one allele is distributed to each gamete according to this law.
The law of segregation helps in making a different combination of alleles in a particular species or population and leads to variation in genetics. It makes sure that traits distribute to each generation randomly.

What charges are needed in the objects in order for attraction to occur?
A) A positive charge
B) A negative charge
C) A positive charge and uncharged
D) A negative charge and uncharged
Answer:
The balloon would likely become charged and its charge would exert a strange influence upon other objects in its vicinity. If some small bits of paper were placed upon a table and the balloon were brought near and held above the paper bits, then the presence of the charged balloon might create a sufficient attraction for the paper bits to raise them off the table. This influence - known as an electric force - occurs even when the charged balloon is held some distance away from the paper bits. The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects.
Explanation:
Answer:
I think it’s C because positive charge and uncharge can attract each other
It can’t be D because none of the photos have a negative charge
Approximately how many total ATP equivalents are generated by the complete oxidation of one molecule of acetyl CoA via the citric acid cycle?a) 1.5b) 2.5
c) 10
d) 30
Answer:
C. 10 ATP molecules
Explanation:
In the citric acid cycle is a series of eight reactions steps in which a two-carbon molecule, acetyl-CoA, enters the cycle through citrate and two atoms of carbon are removed as two molecules of carbon dioxide.
The energy generated by the complete oxidation of one molecule of acetyl CoA via the citric acid cycle is conserved in the production of three NADH molecules, one FADH₂ and one ATP molecule. Each NADH molecule transfers two electrons to oxygen in the electron transport chain, forming 2.5 ATP molecules each in the process. Similarly, an FADH2 molecules transfers two electrons to oxygen in the electron transport chain yielding 1.5 ATP molecules.
Total ATP molecules produced:
3 NADH + 1 FADH2 + 1 ATP = (2.5 × 3) + (1.5 × 1) + 1 ATP = 10 ATP molecules
Therefore, 10 ATP molecules are generated by the complete oxidation of one molecule of acetyl CoA via the citric acid cycle.
