Answer:
Two processes convert ADP into ATP: 1) substrate-level phosphorylation; and 2) chemiosmosis. Substrate-level phosphorylation occurs in the cytoplasm when an enzyme attaches a third phosphate to the ADP (both ADP and the phosphates are the substrates on which the enzyme acts).

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).

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.

The factor in the Southwestern desert ecosystem that is abiotic is precipitation.
What are abiotic factors?Abiotic factors are the non-living components of an ecosystem influencing the living organisms' distribution in an area. Precipitation is an abiotic factor that provides water for plants and animals to survive and is a very important part of the ecosystem.
In the Southwestern desert ecosystem, the low precipitation levels resulted in an arid environment which results in the presence of a unique array of plant and animal species that have adapted to survive in these conditions.
Temperature is also another important abiotic factor in the Southwestern desert ecosystem. The high temperatures during the day and low temperature at night influence the behavior and survival of the animals and plants that live in this environment. Wind patterns, soil type, sunlight, etc. are other abiotic factors.
Therefore, the factor in the Southwestern desert ecosystem that is abiotic is precipitation.

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.

A short story of how water cycle works
Answer:
A summary of the water cycle
The heat of the sun provides energy to make the water cycle work. The sun evaporates water from the oceans into water vapor. This invisible vapor rises into the atmosphere, where the air is colder. Water drops form in clouds, which then fall to Earth as precipitation (rain and snow).
Explanation:
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.

A herd of zebras has 9 males and 62 females.
During a one-year period, 22 foals that are born
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.

How does heat transfer between the atmosphere and the ocean affect regional climate?
Explanation:
Both the ocean and the atmosphere transport roughly equal amounts of heat from Earth's equatorial regions - which are intensely heated by the Sun - toward the icy poles, which receive relatively little solar radiation.
The ocean and atmosphere are constantly in a process of energy exchange (heat transfer) as the ocean bodies serves as heat trap which absorbs the larger portion of the Sun's radiation, which is distributed to surrounding areas as sunlight subsides, with the ocean water also losing moisture due to evaporation.
Areas very close to the ocean, topical regions experience the highest level of evaporation and they inturn experience the highest amount of Rainfall. Hence, dictating the regional climate of the tropics.
Ocean currents also play a major role in ensuring distribution of heat, precipitation and warmth between the equatorial and tropical regions, Hence, patching a sort of balance in regional distribution of heat and Rainfall.

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.
