Which of the following are the alleles for a heterozygous pea plant?
A. Gg- Green color
B. GG- Green color
C. gg- yellow color
Heterozygous means the individual has one copy of the recessive gene and one for the dominant gene. That means the genotype will contain one capital letter and one lowercase letter. In this case, which is complete dominance the dominant gene will manifest in the heterozygous form.
The correct answer is A. Gg-Green color
How can traits affect fitness and how
can natural selection change the
presence of certain alleles over time?
Answer: Natural selection allows the survival of organisms with beneficial traits.
Explanation:
Natural selection can be defined as the differential survival and reproduction of the members of the population that have beneficial phenotypic traits to survive in unfavorable environment. These organisms reproduce and pass on their traits to the next generation such species does not extinct in future.
The natural selection allows evolution of species with the adaptation of new traits so as to allow the survival of the organism.
Which scientific discipline is correctly matched to a contribution to society?
The options are;
A) biology; theory of relativity
B) geology; theory of continental drift
C) ecology; discovering new elements
D) astronomy; developing quantum mechanics
Answer:
B) geology; theory of continental drift
Explanation:
Looking at the options;
-theory of relativity is a topic in physics originated by Einstein. Thus, it is matched to physics and not biology.
- theory of continental drifts are related to plate tectonics where it explains how continents shift position on Earth's surface. This is a branch of Geography and is thus correctly matched.
- discovering new elements is a topic under chemistry and not ecology. Thus, this is not matched correctly.
-developing quantum mechanics is a topic in physics that deals with the relationship between energy and matterwith respect to atomic and subatomic scale. Thus, it is not well matched.
Therefore correct answer is option B
3. On a particular planet, it takes 850 J for a 50 kg remote probe to launch
itself up 2 m. What is the gravitational field strength on the planet?
Answer:
the gravitational field strength is 8.5 N/kg .
Explanation:
PE = mgh
where,
PE is Potential Energy
m is the mass
g (a) is the acceleration
h is the height
Substitute the value we get
→ 850 = 50×a × 2
→ 850 = 100×a
→ a = 850/100
→ a = 8.5m/s²
Acceleration is 8.5m/s².
Now, Calculating the Gravitational Field Strength
doing a aslam answers 70 questions and gets 34 correct answers Imran answers 85 questions and gets 61 correct answers give their scores in percentages and find out who is better at quizzes
Answer:
See the answer below
Explanation:
Aslam answered 34 correctly out of 70;
Percentage score = 34/70 x 100%
= 48.57%
Imran answered 61 correctly out of 85;
Percentage score = 61/85 x 100%
= 71.76%
The percentage score of Imran is 71.76 while that of Aslam is 48.57, hence, Imran is better than Aslam when it comes to quizzes.
The sensor or detector tells the integrating center what needs to be done
True
False
Answer:
True
Explanation:
It is true because a sensor or detector is an organ that detects external stimuli from the environment or changes in both internal and external environment, it then send the information to the integrating center.
The integrating center receive stimulus or information from sensor and activate responses to the stimulus.

What is the purpose of having leak and gated channels for the neuron?
Answer:
Explanation:
The purpose of having leak and gated channels for the neuron is that the leak channels will allow the movement of sodium and potassium across the cell membrane downward from high concentration gradient to low concentration gradient. With the leakage of ions across the cell membrane, there is maintainence of a stable resting potential of cells.
S. cerevisiae occurs in nature on ripe fruit. S. epidermidis naturally occurs on human skin. How do experimental results relate to the natural environment of each microbe?
Answer:
S. cerevisiae needs natural environment present on ripe fruit while S. epidermidis needs natural environment present on human skin.
Explanation:
S. cerevisiae occurs in nature on ripe fruit because the environment is suitable for them that provides food in the form of sugar while S. epidermidis naturally occurs on human skin because it needs wet and humid environment which is available on human body such as armpits. Due to the presence of suitable environmental condition, both S. cerevisiae and S. epidermidis are present on fruits and human skin respectively.
What differences can you see when you compare the nucleus of a dividing cell with that of a non-dividing cell?
Answer:
Explanation:
The difference you can see when you comparethe nucleus of a dividing cell with that of a nondividing cell is that chromosomeswill be seen in the nucleus of the dividing cell because they are visible when acell is dividing apposed to non-dividing cells.
What is the relationship between light intensity and gas production?
Answer:
As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.
___ is the process of producing cellular energy in the presence of oxygen.

Are fibrous proteins heavier than globular proteins in terms of molecular weight? Why?
Answer:
Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.
Please answer this is super easy 6th grade science! Thanks!
Answer:
The answer should be A. lithosphere.
Explanation:
Firstly, let's look at the options:
C. and D, both parts of the Earth at the core, have almost nothing to do with the Earth's crust or tectonic plates except maybe having a passive effect on them.
B. mantle is where the lava that moves the tectonic plates circulates due to convection, which is the reason they move at all. But, it is not where the tectonic plates themselves are.
Therefore, finally, we have A as the answer.
(As a sidenote, the "lithosphere" means the Earth's crust.)

If the frequency of the disorder in the population is 0.0070, what is the percentage of heterozygous carriers
Answer:
15.322 %
Explanation:
Supposing that this is a recessive disorder and the population is in Hardy-Weinberg equilibrium:
p² + 2pq + q² = 1, where
1- the genotypic frequency of the homo-zygous dominant allele is p²,
2- the genotypic frequency homo-zygous recessive allele is q², and
3- the genotypic frequency heterozygous allele is 2pq
Therefore:
q² = 0.007 >> q = √ 0.007 = 0,0836
p = 1 - q = 1 - 0,0836 = 0.9164
2pq = 2 x 0.9164 x 0,0836 = 0.15322 (or 15.322 %)

55) Cells require which of the following to form cilia or flagella?
A) centrosomes
B) ribosomes
C) actin
D) A and B only
E) A, B, and C
Answer: D) A and B only
Explanation:
Centrosomes and Ribosomes are both present in the animal cell with both of them having different roles. Centrosomes have roles in cell divisions as they maintain chromosome number during the process and Ribosomes are in charge of the synthetization of proteins.
These two share a role together which is that they are both needed by the cell in order to form either cilia or flagella.
A man has hemophilia, but his parents do not. Using H for normal and h for hemophilia, give the genotype of his father, mother, and himself in that order.
Answer: refer to the attached image for the genotypes.
Explanation:
Hemophilia is a blood clotting condition in an X-linked recessive pattern that is inherited from parents by offspring. In order to be expressed in a female, the mutation must have both X chromosomes. In males, only the one X chromosome that he has to transmit needs to be present.

structural adaptations of phloem
Answer:
strong
Explanation:
Answer:
The cells that make up the phloem are adapted to their function. Each sieve tube has a perforated end so its cytoplasm connects one cell to the next Companion cells. transport of substances in the phloem requires energy. One or more companion cells attached to each sieve tube provide this energy.
