O mushrooms, puffballs, rusts
O morels, mushrooms, chytrids
O chytrids, truffles, puffballs
Truffles, morels, yeast are classified as sac fungi. So, the correct option is (A).
What is Sac fungi?Ascomycota also known as sac fungi, belong to a group of fungi (Kingdom Fungi) characterized by a saccular structure, the ascus, which contains four to eight ascospores in the sexual stage.
These are divided into subgroups based on whether the asci are produced singly or in one of several types of fruiting structures, or ascocarps, and on the method of discharge of the ascospores.
Many ascomycetes are plant pathogens, while some are animal pathogens, where some are edible mushrooms, and many live on dead organic matter. The largest and most commonly known ascomycetes include morels and truffles.
Thus, truffles, morels, yeast are classified as sac fungi. So, the correct option is (A).

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.

Explain why if you lightly place a paper clip in water it floats, but if you
disturb the water it sinks.
The paper clip, which has a far higher density than the water, can float because of the strong surface tension.
What is the surface tension of liquid?Because water is polar, its molecules are attracted to one another. Water “sticks” together due to the hydrogen ends, which are positive compared to the oxygen ends, which are negative.
Because of this, there is surface tension, and breaking these intermolecular interactions requires a certain amount of energy.
Whether an object will float or sink in another substance depends on its density. If an object's density is lower than the liquid it is placed in, it will float. If an object is heavier than the liquid it is immersed in, it will sink.
Therefore, if you lightly place a paper clip in water it floats, but if you
disturb the water, it sinks.

Clean air is of concern to most Americans. The Environmental Protection Agency (EPA) has set forth guidelines for business, industry, and private citizens to follow to help improve air quality. All but one is a guideline of the EPA to improve air quality. That is
Answer: The question is incomplete and the options are not given, the options was found on another websites , here are the options
A. check and replace air filters regularly
B. reduce, reuse, and recycle whenever possible.
C. fix leaking faucets and minimize outdoor water use.
D. reduce the amount of particulate matter by limiting burning.
The correct option is C.
fix leaking faucets and minimize outdoor water use.
Explanation:
Fix leaking faucets and minimize outdoor water use is a guideline for the environmental protection agency because fixing faucet will allow the device to deliver water to a plumbing system. If the faucets is leaking it will lead to water wastage and pollutants having entry through the water system, when it is fixed it will minimize the outdoor water use.
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.

survive and 25 adults die. Six females join the
herd. Three males and 11 females leave the herd.
Has the herd reached its carrying capacity for this
ecosystem? How do you know?
a. The herd has reached its carrying capacity
because the growth rate is negative.
b. The herd has reached its carrying
capacity because the growth rate
is positive.
c. The herd has not reached its carrying capacity
because the growth rate is negative.
d. The herd has not reached its carrying
capacity because the growth rate
is positive.
Answer:
C. The herd has reached its carrying capacity because the growth rate is negative.
Explanation:
The herd has not reached its carrying capacity because the growth rate is negative. Hence option c is correct.
What is ecosystem?Ecosystem is defined as a location where a bubble of life is created by the interaction of plants, animals, and other species with the weather, topography, and other factors. In ecosystems, biotic and abiotic factors or nonliving components coexist. Human welfare and survival depend on healthy terrestrial ecosystems because they give us access to critical goods and advantages.
Clumps can disperse in a region when there is an unequal distribution of resources like food, water, moisture, temperature, or other materials. the three benefits that one organism might get by coexisting in a population with clumped dispersal. There is more access to food resources, less movement required for individuals to find mates, and improved predator protection for organisms.
Thus, the herd has not reached its carrying capacity because the growth rate is negative. Hence option c is correct.

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.
