Which of the following is true about how science is used to solve a problem?
It is affected by social concerns.
It is unaffected by political concerns.
It is not influenced by economic conditions.
It is not determined by external local factors.
Answer:
It is affected by social concerns.
Explanation:
Scientific thinking is useful for everyone in everyday life, not only for scientists, so it is important to know social concerns in order to solve various problems of society in general.
the inheritance of genetic traits from parents to children follows predictable rules. Knowing that each parent contributes genes equal to each child what determines an inherited trait such as eye color
The correct answer is...
The interaction between dominant and recessive genes.
1. Which biotic factors do you see in the photo?
2. Which abiotic factors can you detect in this photo?
3. In what ways does one biotic factor interact with the abiotic factors?
4. Pick one biotic factor and change it dramatically somehow. How will this change affect the aquarium?
5. Pick one abiotic factor and change it dramatically somehow. How will this change affect the aquarium?
Answer:
1. Biotic components of the ecosystem refer to all the living organisms present in the ecosystem. So, fishes and plants would be the biotic components.
2. Abiotic components of the ecosystem refer to the physical or non-living component of the ecosystem. Thus, water and rocks would form the abiotic component of the given ecosystem.
3. The biotic and abiotic components are linked through energy flow and biogeochemical cycles. For example, fishes get oxygen from water and excrete their waste product in the water. Similarly, plants also get carbon dioxide and water for photosynthesis from the abiotic component.
4. Change in the biotic component would disturb the whole ecosystem. For example, if plants are reduced or removed from the ecosystem, enough amount of food and oxygen would not be produced. Similarly, if the number of fishes is increased to a large number, then it might be difficult for the ecosystem to sustain for a long time.
5. The abiotic component is also essential for the ecosystem. Any change in the abiotic component can produce severe effects on the ecosystem. For example, if water is removed or highly polluted then the living organisms would not be able to survive in the ecosystem.

Explanation:
Genetically-different __________ are the kind of cells made from meiosis.
parents
splices
gametes
Gametes are the genetically different kind of cells which are produced as a result of meiosis. Meiosis is a reductional division in which the chromosomes are reduced to half. Genetic variation in the gametes is due to crossing over between two non-sister chromatids of a homologous chromosomes during meiosis.

If water vapor continues to increase in our atmosphere, what changes would you expect in fresh water lakes?
A: lake temperatures will decrease, but dissolved oxygen in water will increase.
B: lake temps will decrease along with dissolved oxygen.
C: lake temps will increase, but dissolved oxygen will decrease.
D: lake temps will increase along with dissolved oxygen.
Answer: Option (C)
Explanation:
Temperature and dissolved oxygen is inversely proportional to each other i.e if temperature is high then dissolved oxygen will be low and if temperature is low then dissolved oxygen will be high.
Thus, we can conclude that when the water vapor content increases in the atmosphere, the lake temperature eventually will rise whereas the dissolved oxygen will get subsequently reduced.
Hence the correct option is (C)
All animals share the following characteristic: a. being a consumer c. not having cell nuclei b. having cell walls d. budding
okay consider a cross of beetles with exoskeleton allies B and b and leg size alleles N and n. the male parent is heterozygous in both traits. the females parent is homozygous recessive in both traits
Answer
This cross will generate puppies with the genotypes of 25% BbNN, 25% Bbnn, 25% bbNn and 25% bbnn.
Explanation:
In this case the parent beetle has genotype BbNn and the mother beetle is bbnn. To solve this intersection, we have to remember Mendel's law of independent segregation and perform the traits intersections separately and multiply the percentages later.
1 - Characteristic of the exoskeleton: Bb x bb that gives us 50% Bb, 50% bb.
2 - Leg feature: Nn vs nn which gives us 50% Nn and 50% nn as well.
Finally, that means the cross of beetles have a chance to origin puppies with (0,5 * 0,5) in each different trait, resulting in the genotypes of 25% BbNN, 25% Bbnn, 25% bbNn and 25% bbnn

Jupiter, Saturn, Uranus, and Neptune are a known as ________. a. terrestrial planets c. dwarfs b. ringed giants d. gas giants Please select the best answer from the choices provided A B C D
Answer : Option D gas giants
Explanation :
A gas giant is a plant that is large in size and is mainly made up of hydrogen and helium and hence, the name.They are also known as failed stars as their composition is the same as that of stars.They have a very small rocky core.Jupiter, Saturn, Uranus and Neptune are the four gas giants that are present in our solar system as they have the characteristics described above.How can transposable elements promote functional genetic diversity in a population?
The answer is a transposable element may cause genetic diversity by any of the above methods. A rapid way for natural evolution to alter a protein-coding gene so it encodes a protein with a different structure and function. The results often duplicate transposition of the same genetic material.

Which of the following is most likely to happen if a cell is not able to divide?
The cell will create two identical daughter cells.
The cell will absorb oxygen during photosynthesis.
The cell will not be replaced when it is damaged.
The cell will not release carbon dioxide during respiration.
The most likely to happen if a cell is not able to divide is The cell will not be replaced when it is damaged.
Why is it important for the daughter cells to divide a second time in meiosis?Because meiosis makes cells that are fated to become gamete this decrease in chromosome number is required without it, the association of 2 gametes during fertilization.
Thus, option "C" is correct, is most likely to a cell is not able to divide.

A student
conducted an experiment that used two rose plants to determine if a liquid formula for fertilizer was better than a dry formula. He tested each fertilizer on a single plant for one , and he concluded that the liquid formula was better. When he described his conclusion to his , she told him he needed to conduct additional trials. The most likely asked for additional trials because
Answer:
A scientific experiment is designed in a way that it includes all the variables to be tested as well as the control group.
In the given question, the student performed the experiment to test if liquid fertilizer is better than dry fertilizer or not?
So, to test this student performed the experiment on a small sample size that is only one plant and lacked a control group which could act as a reference to the experiment. Therefore the additional trial should include a large sample size to remove the error and the control group which provide data to compare.
In double stranded DNA, 13% of the strand is found to be adenine. How much would you expect thymine to be present?
13%
74%
26%
37%
The amount of thymine in double stranded DNA would be equal to that of adenine, which is 13%, according to Chargaff's rules.
Explanation:In double stranded DNA, if 13% of the bases are adenine (A), then we can expect the same percentage, 13%, to be thymine (T) according to Chargaff's rules. This is because adenine always pairs with thymine, forming hydrogen bonds. Hence, the amount of adenine equals the amount of thymine in a DNA molecule. Consequently, the percentage of thymine present would also be 13%, making option A the correct answer.

a. Cells spontaneously arise from carbon and nutrients carried in the bloodstream.
b. The cell is the basic unit of structure and organization in organisms.
c. All cells come from pre-existing cells.
d. All organisms are composed of one or more cells.
Answer:
a. Cells spontaneously arise from carbon and nutrients carried in the bloodstream is not the part of the cell theory.
Explanation:
Cell theory is a biological hypothesis that states that all beings are made up of cells, that cells are the basic structural/organizational unit of all organisms, and that all cells originate from pre-existing cells. It was first proposed in the mid-nineteenth century.
