Answer:
After a few decades, there will be only small fishes, as directional selection will be acting in this population.
Explanation:
Directional selection increases in the proportion of individuals with an extreme phenotypic trait. Individuals expressing the other phenotypic extreme might be receiving different pressures that drive them to decrease their fitness. These pressures, in general, might be related to food access, niches availability, reproduction, predation, among others.
In this example, there are two extreme phenotypic traits, large and small fishes. Large fishes are being predated by fishermen, who prefer large individuals rather than small ones. Large fishes fitness start to decline, as they are being hunted. Only small fishes get to survive, they get to reproduce and hence, to have better fitness. Natural selection is acting on the size of these animals, favoring the small-sized ones. Over a few decades, the directional selection will increase the proportion of small fishes.
There are certain types of fish in the lake that the fishermen can catch using the nets. As they don't like the small ones which get out of the holes of the net.
As after a few decades there will be only small fish remaining As the directional selection will be acting on the population. Directional selection is when individuals with traits and one side there are better chances of survival.Learn more about the certain type of fish in a lake.

What organelle(s) gives plant cells their shape?
O A chloroplasts
O Blarge central water vacual
O C cell wall
O D both B and C contribute to the plant cells shape.
Answer:
A. Chloroplasts
Explanation:
Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.
Hope this helped. Have a Great Day!!!
Answer:
options 1 chloroplasts is the correct answer
will mark correct answer as brainliest!
plant cell
label the boxes with words from the word bank
Answer:
Explanation:
cell wall – provides rigid structure and protection; made of cellulose (dark green)
cell membrane – surrounds the internal cell parts; controls passage of materials in and out of the cell cytoplasm – everything inside of the cell membrane except for the nucleus (light green)
nucleus – control center of the cell; contains DNA (light pink)
nucleolus – composed of protein and RNA; involved in ribosome production (dark pink)
cytoskeleton – provides strength and shape to the cell; network of protein fibers (orange)
endoplasmic reticulum (ER) – passageways that transport proteins within the cell (purple) mitochondria – produces energy (rust or red)
chloroplast – uses the energy of sunlight to produce glucose during photosynthesis (medium green) vacuole – vesicle that provides storage of water and other materials; full vacuoles provide support (blue) lysosome – vesicle that contains substances that break down materials (navy)
Golgi body – packages and transports proteins from the ER to other parts of the cell (gold)
ribosomes (the dots) – where proteins are made in the cell

The structures responsible for completing the breakdown of carbohydrates into usable energy for the cell are the
A. Nuclei
B. Mitochondria
C. Ribosomes
D.chloroplasts
Answer:
The correct option is;
B. Mitochondria
Explanation:
The mitochondria are the organelle of the cell bund to the membrane that are referred to as the cell powerhouse they function in the same manner as the digestive system, such that they take in raw nutrients which are broken down to produce energy containing molecules which makes up the majority of the chemical energy required for the various biochemical reactions of the cell in a way such that the energy they produce are stored in adenosine triphosphate (ATP) molecules.
Answer:
B. Mitochondria
Explanation:
The mitochondria are cellular organelles found in eukaryotic cells. They are structures involved in cellular respiration, which is the process whereby energy in form of ATP is synthesized for use by the cell.
Cellular respiration in eukaryotes occurs in stages including glycolysis, kreb's cycle and oxidative phosphorylation. All these processes combine to breakdown carbohydrates (glucose) into usable energy for the cell. The structures responsible for this process is MITOCHONDRIA.

Certain cells, such as those along the digestive tract, need to absorb a lot of materials. What unique features do you notice about the shape of these cells? How might this improve their ability to absorb materials?
Cells are the functional and structural units of life. The cells make up the tissues, organs, and organ systems. The cells based on the shapes and properties differ in their functions.
In the given image, the special features of the cells of the digestive tract are microvilli.
Villi are the finger-like projections present on the intestinal wall. These will function in increasing the surface area to enhance the digestion process.
On the surface of the villi, numerous micro-hair-like projections are presently known as microvilli. The microvilli are the help in increasing the surface area of the villi.
These finger-like projections create a wave or brushing-like movement for the increased absorption and surface area.
Therefore, the given image is of microvilli that helps in increasing the surface area.

phenotype and genotype of this punnet square?
Answer:
Phenotype: whatever the capital P is
PP and Pp
Explanation:
So the genotype is PP 1/2 Pp 1/2
and so in your question it should have whatever the "PP" and "Pp" stand for in your question would be it. So lets say red flower = PP and Yellow flower = Pp so it would be Red Flower 1/2 and Yellow Flower 1/2

theory?
A) Plants and animals are made up of structural
units known as cells.
B) Mitochondria and chloroplasts contain genetic

C) All cells arise from preexisting cells.
D) The cell is the basic functional unit of all living
things.
The statement describes an exception to the cell theory - B) Mitochondria and chloroplasts contain genetic material and can replicate.
The cell theory is the theory that is given by German researchers Theodor Schwann, Matthias Schleiden, and Rudolph Virchow. This theory states three major principles:
All living organisms are composed of one or more cells.The cell is the basic unit of structure and organization in organisms.Cells arise from pre-existing cells which means cells divide and pass on hereditary informationenergy flows within cells.Thus, the statement describes an exception to the cell theory - B) Mitochondria and chloroplasts contain genetic material and can replicate.

What do cells need to complete aerobic cellular respiration
Answer:
Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
Explanation:
Cells require Oxygen and glucose to complete aerobic cellular respiration
During Aerobic Cellular respiration, glucose and water reacts with each other to release energy in the form of ATP that is used/stored up in the cells of the organisms. below is the cellular respiration reaction
cellular respiration :
[tex]C_{6} H_{12} O_{6} + 6O_{2} ---->6CO_{2} (gas) + 6H_{2} O + energy[/tex]
Hence we can conclude that Cells need Oxygen and glucose to complete aerobic cellular respiration
