What do cells in the spongy mesophyll layer have that makes gas exchange easier?
Answer:
The spongy mesophyll cells are adapted for gas exchange. They are loosely-packed with large intercellular air spaces where gases can readily diffuse. They have fewer chloroplasts than palisade cells, so carry out less photosynthesis . When the plant is photosynthesising during the day, these features allow carbon dioxide to diffuse into the spongy mesophyll cells, and oxygen to diffuse out of them.

1. What is the gradual change in populations over time?
2. What is the idea that species originate in small gradual steps over time?
1. Gradualism
2. evolution
Answer:1.Gradualism is an evolutionary model that refers to the tiny variations in an organism or in society that happen over time to make a better fit for animals and humans in their environment. These variations allow them to survive and thrive, resulting in a slow and consistent process of change in the whole population.
2.Phyletic gradualism is a model of evolution which theorizes that most speciation is slow, uniform and gradual. When evolution occurs in this mode, it is usually by the steady transformation of a whole species into a new one (through a process called anagenesis).
Explanation:
In some plants, phloem cells are connected end-to-end by sieve plates, creating a direct connection between the cytoplasm of phloem cells. What is one possible benefit of having phloem cells connected in this manner?
Answer:
Explanation:
This is because the sieve plate interconnected like that help in exchange of substances or transport of substances between element cell and it act as a barrier to prevent the sap from been loss when phloem is damaged or cut. The sieve plates form the sieve tube which is the conducting element of the phloem. It is formed from series of elongated cells that are interconnected by perforations in their walls.

The organization of similar organisms into groups helps scientists understand how living things are related. It
also allows scientists to communicate about all forms of life. Scientists organize the living world using a process
called taxonomy, which is the science of classifying organisms based on shared structures, functions, and
relationships to other organisms. Scientists use a branching system of classification, and over the years, due to
new discoveries, the branching system has changed and grown.
Recently, scientists broadened the branching system of classification. Currently, the broadest group is the

which of these fronts is most likely to produce a thunderstorm?
whoever to answer first gets a brainliest!!
Answer:
Cold front
Explanation:
Glycolysis, or the breakdown of glucose, is a process used by almost all organisms as a way to release energy stored within glucose molecules. This energy can then be stored in cells as ATP, which powers cell processes when needed. What does this show, in terms of the evolutionary history of cells using glycolysis?
Answer:
It was one of the earliest metabolic pathways.
Explanation:
The evolutionary history of cells using glycolysis shows that It was one of the earliest metabolic pathways which is used by nearly all of the organisms on earth for the production of energy for the survival, growth and development. The first organisms used this pathway for the generation of energy and with the passage of time, new pathways are also formed as the organism evolved so we can conclude that glycolysis is the first pathway used by the earliest organisms.
Some desert plants respond to darkness by opening their flowers at night to lure in pollinators. In
this situation, a plant's response system is working in conjunction with the —
immune system.
vascular system.
reproductive system.
root system.
Answer:
B
Explanation:
In this situation, a plant's response system is working in conjunction with the vascular system. Therefore, option B is correct.
What is a vascular system?The complex network of conducting tissues known as the plant vascular system connects all organs and carries water, nutrients, organic compounds, and different signaling molecules throughout the body of the plant. The primary transport systems of plants, xylem and phloem, make up vascular tissue. They often coexist in vascular bundles that cross the roots, stems, and leaves of all plant organs. Water and dissolved ions are moved upward through the plant through the xylem, starting at the roots.
Clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms are examples of vascular plants (flowering plants). The group is known by its scientific names, Tracheophyta, and Tracheobionta.

2. In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Which cellular organelle was most likely on the filter paper, and what process was it performing?
Answer:
Mitochondria; cellular respiration.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Thus, the cellular organelle which was most likely on the filter paper is mitochondria and the process it was performing is called cellular respiration.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP).
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
