Identify the tonicity of the solution surrounding the cell.
Answers
Answer:
Hypertonic
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

Infer how and why humans have changed species through breeding.
Answers
Answer:
Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve. All of our domesticated species, including crop plants, livestock, and pets, are the products of artificial selection for desirable traits, such as seeds and fruits that do not disperse readily, increased meat and milk production, and docile behavior.

Which of the following is NOT true of plants?
A
Plants help remove some toxins from the air.
B
Some plants pollinate with help from the wind.
С
Plants remove carbon dioxide and release oxygen into the air.
D
Plants remove oxygen and release carbon dioxide into the air.
Answers
Answer:
D
Explanation:
Answer:
D
Explanation:
Knowing what you know about photosynthesis, explain how the process may reduce
global warming (caused by too much carbon dioxide in the atmosphere).
Answers
Through the pores called stomata in their leaves, plants take in carbon dioxide from the atmosphere that they use for photosynthesis. ... But when carbon dioxide levels increase, plants' stomata shrink, releasing less water into the air and reducing the cooling effect.

which of the following is not true about an allele?
A. alleles are found at the same place on a chromosome
B. alleles have a dominant and recessive form
C. an allele is never independently assorted and passed down randomly
D. and allele is one of two or more forms of a gene
Answers
Answer:
C
Explanation:
I guess it's C but not conform
C. An allele is never independently assorted and passed down randomly.
What is an allele?Alleles are found at the same place on a chromosome, known as a locus. They can have a dominant and recessive form, meaning that one form of the allele may be expressed over the other in the phenotype of an organism. An allele is one of two or more forms of a gene, which are variations of a particular gene that can produce different traits in an organism.
However, alleles are not always passed down randomly. In meiosis, the process of cell division that produces gametes (sex cells), the alleles of a gene are independently assorted and passed down to the offspring. This means that each gamete receives one copy of each allele at random, which can result in a mix of alleles in the offspring. However, the exact combination of alleles that an offspring receives depends on the combination of alleles that its parents had, which can influence the probability of certain alleles being passed down.

The combination of absolute and relative dating allows scientists to determine the ages of rocks and fossils. Absolute dating provides evidence that helps us estimate the ages of Earth. How can scientists find the absolute age of igneous rocks?
Answers
Answer:
By radiometric dating
Explanation:
The relative age of a rock sample is determined by comparing a (or the fossils it contains) to other layers. Relative age of a rock sample can be determined by looking at the position of various rock layers.
Absolute age of a rock sample is the numerical. Absolute age can be determined by using radiometric dating.
According to Oxford dictionary, radiometric dating is "a method of dating geological specimens by determining the relative proportions of particular radioactive isotopes present in a sample."

Which of the following does not add CO2 to the atmosphere?
A. Cooking with gas B. Planting trees C. Burning wood D. Riding in a bus
Answers
Explanation:
carbon dioxide is added are the atmosphere naturally with organisms respire or decompose carbonate rocks are weathered,forests fires occur,and volcanoes eript.Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossils fuels and forests and the production of cement.
let me know if u got it right
From the options the action that does not add CO₂ to the atmosphere is : ( B ) Planting trees
When Trees are planted more oxygen is added to the atmosphere, during photosynthesis because plants releases Oxygen into the atmosphere during photosynthesis.
Cooking with gas releases CO₂ into the atmosphere while burning up the gas to generate heat. For a material to burn in nature it utilizes oxygen from the atmosphere while adding Carbon into the atmosphere.
Hence we can conclude that the action that will not add CO₂ into the atmosphere is Planting trees.

Identify: What are the reactants of aerobic cellular respiration? What are products?
Answers
Answer:
Aerobic breathing disrupts glucose and combines disintegrated products with oxygen that generates water and carbon dioxide. The carbon dioxide is a waste of aerobic breathing because there is no demand for cells.
Cellular respiration reactants:
Glucose and oxygen.
Cellular Respiratory Products:
CO2 and water (H2O); ATP & Heat
Anaerobic breathing: breathing occurring in the absence of oxygen that makes certain ATP still alive to cells.
Explanation:
Cellular Respiration is the mechanism that releases energy in the presence of oxygen by breaking down food molecules.
Cellular breathing = Aerobic breathing
In mitochondria, aerobic breathing takes place.
Some of the energy generated by food decomposition is stored as ATP and some as heat.
ATP is an energy storage molecule used by every cell as its source of energy.
