Diatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric.
What are Diatoms?Any member of the vast group of several genera of microalgae that can be found in the world's oceans, streams, and soils is referred to as a diatom.
Diatoms can photosynthesize, which allows them to change the dissolved carbon dioxide in the water into oxygen.
For higher-ranking organisms in the food chain, like invertebrates and tiny fish, they serve as a major source of food. In the energy and nutrition cycles of water resources, diatoms can also be vital players.
Diatoms can be divided into two shapes: pennate diatoms, which make up the majority, are broadly bilaterally symmetric, and central diatoms, which make up the minority.
Thus, these are the characteristics of diatoms.

5. What would be the effect if a gene has a mutation in the location of the stop codon? (4 points)
During translation protein synthesis won't stop when it should so amino acids will continue to be placed and the peptide will be bigger.
Answer:
In genetics, a point-nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a point-nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and usually nonfunctional protein product.

1. How did the colors of each type of prey affect its population size over time?
2. What color rabbit seemed to camouflage the best in this snow habitat and why? What
color rabbit seemed to camouflage the best in the summer habitat and why?
Answer:
The more an animals color matches their surroundings, the more likely it is for survival. White rabbits fur matches the snow, and brown rabbits fur blend with the dirt
Explanation:
The colors that stand escape the many would be red and blue and the one's camouflage is mostly brown, green, and yellow, swinging on its place and surroundings.
What is the Color rabbit?
The prey that is more delicate in color lasts extended. As the duration goes on, the white prey lasts extended than the blue colors as they blend into their surroundings sufficiently.
The green, red, and orange varied practically extinct over the 3 generations because they could be stained easier and could not blend into their surroundings.
The colors were very necessary for how it influenced the people because the more brilliant the color the more predators it's going to seduce and the colors such as green and brown are more camouflage.
The more an animal's color approximates its surroundings, the more possible it is to survive. White rabbit's fur approximates the snow and brown rabbits' fur in combination with the dirt.

What is the major difference during cytokinesis in eukaryotes with or without a cell wall?
Answer:
Cytokinesis in eukaryotic animal cells do not have a cell wall, it occurs through a strangulation process carried out from the plasma membrane, this process is called segmentation. Plant cells are characterized by cytokinesis based on septate, since the cell wall does not allow strangulation.
Explanation:
Cytokinesis means: cell division, it is a cellular process parallel to mitosis whose purpose is the division of the stem cell's cytoplasm between daughter cells. In animal cells, cytokinesis occurs by cleavage. At the end of anaphase and during telophase, the central part of the cell narrows, forming the segmentation groove, which deepens (strangulation). Plant cells, as they lack centrosomes, will form the achromatic spindle from two polar caps. In this case, cytokinesis does not occur by strangulation, but a cell wall is formed between the two daughter cells. This septum, called a fragmoplast, is formed from vesicles from the Golgi apparatus.
The major difference during cytokinesis in eukaryotes with or without a cell
wall is in the formation of cell plate in cells with cell wall while in animal
cells cytokinesis occurs through the formation of a cleavage furrow.
Cytokinesis is the process of cell division in which the cytoplasm divides
into two. Plants have cell walls while animals lack cell walls.
Animal and plant cells form cleavage furrow and cell plate respectively
which aids division into two equal parts.

how does a beneficial trait increases an organism's survival and potential reproductive success.
Answer:
This cumbersome trait significantly decreases the male's chances of survival. ... natural selection: that is, that organisms better adapted to their environment would benefit from ... the individual's reproductive success, even at the expense of their survival (Darwin 1871). ... A successful male can potentially sire many offspring.
Explanation:
The beneficial trait increase the survival and potential reproductive success of the organism as they help organism to thrive in their unfavorable changing environment.
Natural selectionThe natural selection can be defined as the differential survival and reproduction of those organisms which have beneficial traits over others.For example, the color change in chameleon helps them to remain undetected from predator population as well as from prey so it helps in increase in rate of survival of chameleon also helps them to reproduce and increase in number.Hence, beneficial traits increase the rate of survival and reproduction of organisms.

Hoped I helped you out please mark me brainliest!!!
With the creation of the microscope, humans were able to observe plant and animal cells, and as technology advanced, scientists were able to learn more about these various types of cells.
What is a microscope?A microscope is a device that can be used to examine small objects, including cells. The image of an object is magnified in the microscope by at least one lens.
In most cases, the light is focused on the sample by passing it through a condenser.
After passing through the sample, the light passes through the objective lens, which magnifies the image of the sample, and then to the oculars, where the enlarged image is viewed.
The discovery of the green fluorescent protein (GFP), the development of increasingly sophisticated microscopes, and the development of in vitro assays that faithfully reproduce cellular functions are just a few examples of technological advances that have fueled many areas of cell biology.
Thus, it can be concluded that the advancements in technology help scientists better understand process of cell division.

All energy comes from the sun. In 2-3 sentences, explain how it is transferred from one organism to another.
Answer:
When the sun rays come down into the atmosphere and the plants on the ground use photosynthesis to reproduce and eat. If an animal, for example, a bunny, eats grass the energy will be transferred to the bunny. If a fox eats the bunny, the energy transfers to the fox. the amount of energy will be reduced each time something is eaten because it keeps being consumed over and over.
