Which statement is supported by the cell theory?
All animal cells are the same size.
All plant cells are the same shape.
Similar organisms all have the same number of cells.
Cells are the primary unit of structure in living organisms.
Cells are the primary unit of structure in living organisms.
=============================================================
Explanation:
According to cell theory, cells are the building blocks of any living organism. This pertains to unicellular organisms (aka creatures that are one cell only) or multicellular organisms. This is why choice D is the answer.
Choice A is false because animal cells range in size. The largest animal cell is the ostrich egg that is about 5.1 inches across. In contrast, a neuron in the human body is about 100 microns across.
Choice B is false because plant cells have different shapes depending on the role they play in the plant itself.
Choice C is false. The number of cells varies even within the same species of a plant or animal. This is because the number is randomly determined and changes all the time. Old cells die and new ones are created constantly.
What are some ways in which materials affect how light is transmitted
Answer:
Materials can be classified according to the amount and type of light they transmit. Transparent (trans-PAIR-uhnt) materials allow most of the light that strikes them to pass through. It is possible to see objects through a transparent material. Air, water, and clear glass are trans- parent.

In the spring, Florida plants respond to ________.
A. increased daylight hours and temperature
B. decreased daylight hours and temperature
C. increased daylight hours and decreased temperatures
D. decreased daylight hours and increased temperatures
Answer: Its A
Explanation: You're welcome
Increased daylight hours and temperature. Therefore, option (A) is correct.
Florida flora respond to spring lighting and temperature. Photosynthesis requires sunlight, which increases as days lengthen. Plants develop and metabolically activate due to prolonged sunshine exposure.
Additionally, spring temperatures boost plant growth. Enzymes, nutrient absorption, and cellular mechanisms increase photosynthesis and plant growth at warmer temperatures.
Florida plants start growing when daylight and temperature increase. It grows new roots, leaves, buds, and flowers. These reactions increase energy capture, nutrient absorption, and reproduction, maximising plant output and adding to Florida's ecosystems' vitality and diversity. Therefore, option (A) is correct.

Explanation:
Create two Punnett squares for a fictional trait, “Star-bellied.” “S” represents a dominant star-bellied gene, and “s” represents the recessive trait. For the first Punnett square, the mother and father both have star bellies and the recessive gene; what is the chance their child will have a star-belly? For the second square, the mother has a star-belly and the recessive gene, and the father does not have a star-belly; what is the chance their child will have a star-belly?
The Punnett squares provide information about the genotype and phenotype of individuals produced by the crosses. Cross 1) 3/4 = 75%. Cross 2) 2/4 = 50%.
What is a punnett square?The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.
Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.
Available data:
S represents a dominant star-bellied genes represents the recessive trait.We will assume this is a diallelic gene expressing complete dominance, this is, the dominant allele S completely hides the expression of the recessive allele s.
1st cross: mother and father both have star bellies and the recessive gene
Parentals) Ss x Ss
Gametes) S s S s
Punnett square) S s
S SS Ss
s Ss ss
F1)
Genotype
1/4 = 25% of the progeny is expected to be h0m0zyg0us dominant SS
2/4 = 50% of the progeny is expected to be heter0zyg0us Ss
1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive ss
Phenotype
3/4 =75% of the progeny is expected to have star bellies
1/4 = 25% of the progeny is expected not to have star bellies
The chance their child will have a star-belly is 3/4 or 75%.

Why do you think we thought no life could survive in the deep ocean?
Answer:
The intense pressures in the deep ocean make it an extremely difficult environment to explore
Explanation:
Most of the deep ocean is cold, usually lower than the temperature in your refrigerator. Deep-sea animals don't mind the cold at all, and many can only survive and grow in the cold. Food is scarce in much of the deep sea, in part because photosynthesis only takes place at the ocean's surface where there's sunlight.

In humans, free earlobes (F) is a dominant trait to attached earlobes (f) . If parents with the genotypes FF have a child, what is the probability that the child will have earlobes different from its parents?
Answer:
0%
Explanation:
Mother: FF
Father: FF
From the Punnet Square, we can conclude that the only possible genotype from these parents is FF --> free earlobes.
This means that there is a 0% chance of having a child with attached earlobes.

why do ice cores taken from polar regions contain much older information about earth's climate than ice cores taken from mountaintops
Answer:
Ice cores provide a unique contribution to our view of past climate because the bubbles within the ice capture the gas concentration of our well-mixed atmosphere while the ice itself records other properties. Basically, the lack of melt from polar regions don’t corrupt the record of trapped gases or blur the record of other impurities.

What type of plate boundary caused the feature shown in the photo ?
Answer:
Convergent boundary.
Explanation:
A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.

Which of the following agricultural practices decreases biodiversity?
A.Tiling soil
B.Monoculture
C.Synthetic fertilizers
D.Flood irrigation
Monoculture is an agricultural practice that often decreases biodiversity. Therefore, option (B) is correct.
What is monoculture?Monoculture is the practice of planting only one type of crop on a large scale, which can lead to a reduction in the diversity of plant and animal species in the area. When a single crop is planted over a large area, it can disrupt the natural ecological balance of the region, leading to a decline in the number and variety of species that can survive in the area.
In contrast, tiling soil, synthetic fertilizers, and flood irrigation do not necessarily decrease biodiversity on their own. However, the use of these practices may have negative impacts on the environment, such as soil degradation and contamination of water resources, which can indirectly affect biodiversity.
