Answer:
Producer
Explanation:
Chlorophast is something in a plant. Decomposers eat dead stuff and a protist is any eukaryoticorganism (that is, an organism whose cellscontains a cell nucleus) that is not an animal, plant, or fungus. So yeah. Producer. It's the only thing there that actually produces someting for its self.
The producer is the term for an organism that makes its own source of chemical energy. So the correct option is D.
What is a primary producer?
The primary producers or autotrophs are the organisms that capture their energy from sunlight or other chemical sources derived from nonliving or inorganic sources for their nutrition.
Commonly known autotrophs are Algae and higher plants. Some bacteria and protists are also important autotrophs living in running waters. The heterotrophs obtain energy and materials by consumption of living or dead organic matter.
All animals are heterotrophic organisms. Heterotrophs also include fungi, protists, and some bacteria that depend on dead organic matter for their nourishment. Usually, bacteria make the organic matter more nutrient-rich and also more accessible to other consumers.
These autotrophs and microbial heterotrophs work together to constitute the basic resources of energy that help in supporting higher trophic levels.
Therefore the correct option is D.

Explanation:
If variation in a species was only due to meiosis, how would that limit the evolution of that species?
But the ultimate source of NEW genes or forms of genes (alleles) is genetic mutation. Without mutation, you are bound to run out of various combinations of existing genes eventually, which puts that species in a bit of an evolutionary pickle. Continual genetic diversity (fed by mutations) is necessary for the survival of the species. Less genetic variation means fewer possible adaptations that could result in higher reproductive success, which means the species is more likely to be wiped out by disease or competition for resources or mates.

What would happen if a large organism was made of a single cell?
Answer:
All single-celled organisms contain everything they
need to survive within their one cell. These cells are able to get
energy from complex molecules, to move, and to sense their
environment. ENERGY, it'd need massive amounts of energy to survive.
Organisms made of one cell do not
grow as large as organisms made of many cells. But all living things
need to get energy. All living things also need to obtain materials to
build new structures inside cells or replace worn-out cell parts.
As a result, individual cells grow larger over time. It'd need lots of materials to keep growing.
Organisms respond to changes in the environment. Even microscopic
organisms respond to conditions such as light, temperature, and
touch. The ability to respond allows organisms to find food, avoid
being eaten, or perform other tasks necessary to survive.
For being so large and only a single celled it'd would probably only be found in a very safe environment.

As a way to reduce the number of cases pf malaria a human tropical disease a specific sequence is inserted into the reproductive cells of anopheles mosquitoes which process was most likely used to alter these mosquitoes
Answer: Mosquito transgenesis
Explanation:
The malaria is caused by the malarial parasite, which is transferred to the human or animal host by a mosquito bite named Anopheles. Mosquito transgenesis involves the genetic modification by introducing genes or novel elements inside the mosquito genome of the reproductive cells of the mosquito, which could prevent the replication of mosquito genome and production of progeny mosquitoes. As these mosquitoes can act as a vector for the transmission of malarial parasite, and can spread disease.

Are there any parts of the human body that get oxygen directly from the air and not from the blood? please help! My brain is not working right now
Answer:
Upper-layer skin cells, the cells in the front surface of the eyes
Explanation:
Here is what I found....hope this helps and i'm still trying to wake up XDD
Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen. As a result, the oxygen that is able to passively diffuse into the body directly from the air is not nearly enough to run the whole body. Fortunately, we have lungs that can actively pull in oxygen and transfer it to the blood, allowing the body to transport oxygen to the cells by using the blood like a fleet of delivery trucks. Most of our cells rely on the blood delivery service. However, the cells in the outer layers or our skin and eyes are in direct contact with the atmosphere and can efficiently get their oxygen right from the air.

A cell biologist analyzed four different cells that had varying numbers of each type of organelle.
Based on the numbers of the four types of organelles listed in the table, which cell should the cell biologist hypothesize is most likely to produce the highest number of proteins for export from the cell?
Cell 1
Cell 2
Cell 3
Cell 4
Answer:
A. Cell 1
Explanation:
The Golgi apparatus is located at the base of the cell and serves as a place where proteins are added to lipids, which are then transported to other parts of the cell. It also contains enzymes that break down proteins, carbohydrates and lipids. The Golgi apparatus can be found in most eukaryotic cells.
In the given data the Cell 1 will export the most protein.
How is the protein synthesized in cell ?
The membrane-bound organelle of eukaryotic cells (cells with clearly defined nuclei) known as the Golgi apparatus is made up of a series of flattened, stacked pouches known as cisternae. It is also known as the Golgi complex or the Golgi body. Proteins and lipids are transported, modified, and packaged into vesicles by the Golgi apparatus for delivery to specific locations. It is close to the cell nucleus and in the cytoplasm, next to the endoplasmic reticulum. Plant cells can have hundreds of Golgi apparatus, whereas many types of cells only have one or two.At some point during their maturation, secretory proteins and glycoproteins, cell membrane proteins, lysosomal proteins, and some glycolipids all pass through the Golgi apparatus. The Golgi is also where a lot of the material for the cell wall goes in plant cells.Between the "cis" and "trans" faces of the Golgi apparatus, there are three primary compartments that are structurally polarized. The enzymatic content of each segment of these faces differs significantly, as do their biochemical differences. Most of the time, the membranes on the cis face are thinner than the others.The Golgi apparatus typically consists of four to eight cisternae, though it may contain as many as sixty in some single-celled organisms. Matrix proteins hold the cisternae together, and cytoplasmic microtubules support the entire Golgi apparatus. Other organelles are not involved in the protein synthesis and packing except Golgi apparatus.
