Answer: stem cells
Explanation: They divide to give rise to one daughter cell that continues to be meristematic and another that differentiates. Meristems fall into three categories: apical, lateral, and intercalary. Apical meristems occur at the growing shoot and root tips
Answer:
Meristematic cells are similar to stem cells in animals.

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.
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.

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.

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.
A Flower is reproductive organ? Why?
Answer:
Since the flowers are the reproductive organs of the plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

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.

The french taxonomist who, in 1809, was the first scientist to suggest that organisms that use one part of their body repeatedly would increase their ability was Jean Lamarck
Organisms will not pass acquired physical traits to the next generation.
In his theory, Lamarck proposed how species adapted to the changed environment by passing down acquired physical traits to the next generation. But, after Charles Darwin published his theory of evolution, Lamarck's theory was rejected. Now, it is known that acquired physical traits could not be inherited and epigenetics is a good proof for that.

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

Gametes) S s S s
Punnett square) S s
S SS Ss

Suggest 2 types of learned behaviors and two innate behaviors that you have observed in animals (cats, dogs, whales, humans)
A persistent change in behavior that develops through experience is called Learned behavior. They can be developed by trial and error methods.
What do you mean by Behaviors?Behaviors may be defined as the observable response of organisms to external or internal stimuli.
The two examples of learned behaviors include operant learning (rat pressing lever experiment) and classical conditioning (Food and bell experiment).
The two examples of innate behaviors include feeding their young ones by humans, and fighting against male stickleback fish.

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.

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.
