Answers
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.

When a hawk eats a mouse and then uses the energy from the mouse to fly,
the hawk's body converts to what
Answers
Answer:
It would be Chemical to mechanical
Explanation:
Because food is a chemical source and the hawk flying is a mechanical source.
When a hawk eats a mouse and then uses the energy from the mouse to fly in this case chemical energy is converted to mechanical energy.
What is food chain?Food chain is the sequence of flow of energy in which all the levels get proper food supply and it is the food web which starts from producer and ending at top such as predator species, decomposer and detritivores.
In food chain plants play the role of producers as they are autotrophs and they prepare their own food in the presence of sunlight and all other organisms depend upon plant for food so they are known as producers in the food chain.
The main role of food chain is to understand the importance of each organisms and how they are depend on each other as well as to understand the role of food chain in maintaining ecological balance.
Therefore, When a hawk eats a mouse and then uses the energy from the mouse to fly in this case chemical energy is converted to mechanical energy.

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
Answers
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.

Trace the path of nitrogen from atmospheric N2 into glutamate. Name the enzymes, substrates, products, and coenzymes.
Answers
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]

Suppose a study is being conducted to understand the potential heritability of artistic ability. Specifically, the study wants to recruit pairs of monozygotic and dizygotic twins raised in the same or in different environments. For each scenario, what is the theoretical genetic variance and environmental variance?
1. Monozygotic in the same environment
2. Monozygotic in a different environment
3. Dizygotic in the same environment
4. Dizygotic in a different environment
Answer Bank
0% genetic variance, 100% environmental variance
0% genetic variance, 0% environmental variance
50% genetic variance, 100% environmental variance
50% genetic variance, 0% environmental variance
Using the data collected from the study, what equation could be used to estimate the degree of phenotypic variability of artistic ability that is due to genetic factors?
H² = 2(rmz-rpz), where H² is broad-sense heritability
h2 VA/VP, where h’ is narrow-sense heritability
h2 = 2b, where ha is narrow-sense heritability
Vp = VA + VD + V1 + VE + VGE, where Vp is phenotypic variance
Answers
Answer:
Explanation:
Monozygotic in the same environment
Genetic Variance will be zero and the environmental variance will be zero this is because a monozygotic twin shares the same gene 100% and because they stay in the same environment they are equally exposed to the same thing this makes environmental variance Zero.
Monozygotic in a different environment
Monozygotic in different environment will have an environmental variance 100% this is because they are expose to different environment leading to variation in what they know and 0% genetic variance
Dizygotic in the same environment
They have 0% environmental variation and 50% genetic variation this is because they are fraternal twins and not 100% genetically only 50% of their traits are identical
Dizygotic in a different environment
They will have 100% environmental variance because they are raised in different envrionment leading to variation in idea and what they know and 50% genetic variance because Dizygotic twin are not genetically identical.
The formula to calculate phenotypic variance due to genetic variation is
Hb2 = 2(rmz - rdz) this is in accordance to falconer's formula for twin heritability and its estimatebroad sense heritage.
Where hb2 is broad sense heritability
Genetic and environmental variance determine the phenotypic variability among individuals. 1) b / 2) a / 3) d / 4) c. The equation h² = VA/VP could be used to estimate the degree of phenotypic variability due to genetic factors.
------------------------
1. Monozygotic in the same environment ⇒ 0% genetic variance, 0% environmental variance
Monozygotic twins have no genotypic variation, they share the genotypic charge, meaning there is no difference between them.
Since they grow in the exact same environment, they are exposed to the same factors and, hence, they express no difference.
2. Monozygotic in a different environment ⇒ 0% genetic variance, 100% environmental variance
Monozygotic twins have no genotypic variation, they share the genotypic charge, meaning there is no difference between them.
However, since they were exposed to different environmental factors, they express differences that are due to external elements or conditions.
3. Dizygotic in the same environment ⇒ 50% genetic variance, 0% environmental variance
Part of the genetic charge might be different because they developed from different eggs. They are not identical twins, so they express genotypic variation.
Environmental factors do not play a significant role because twins were equally exposed to the same conditions, so there is no varying environmental influence.
4. Dizygotic in a different environment ⇒ 50% genetic variance, 100% environmental variance
Part of the genetic charge might be different because they developed from different eggs. They are not identical twins, so they express genotypic variation.
Besides, as twins grew in different environments, which means they also express phenotypic differences that are due to external elements or conditions.
Heritability in the narrow sense -h²- refers to the proportion of the phenotypic variability that is influenced by genetic factors.
Heritability in the narrow sense is the measure of the genetic component to which additive genetic variance contributes.
The heritability might be used to determine how the population will respond to the selection done.
The equation that could be used to estimate the degree of phenotypic variability of artistic ability that is due to genetic factors is
h² = VA/VP ⇒ where h’ is narrow-sense heritability

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
Answers
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.

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
Answers
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
